‘Last secret’ of 1967 war: Israel’s doomsday plan for nuclear display
Newly released documents pertaining to the Six-Day War show Israel
planned to detonate a nuclear weapon atop a mountain in the Sinai
Peninsula, as a show of strength, had the Middle East country been on the
verge of losing the 1967 conflict

On the eve of the Arab-Israeli war, 50 years ago this week, Israeli officials
raced to assemble an atomic device and developed a plan to detonate it atop
a mountain in the Sinai Peninsula as a warning to Egyptian and other Arab
forces, according to interviews with a key organiser of the effort that were
published last Monday.

The secret contingency plan, called a “doomsday operation” by Itzhak
Yaakov, the retired brigadier general who described it in the interviews, would
have been invoked if Israel feared it was going to lose the 1967 conflict. The
demonstration blast, Israeli officials believed, would intimidate Egypt and
surrounding Arab states — Syria, Iraq and Jordan — into backing off.

Israel won the war so quickly that the atomic device was never moved to
Sinai. But Yaakov’s account, which sheds new light on a clash that shaped
the contours of the modern Middle East conflict, reveals Israel’s early
consideration of how it might use its nuclear arsenal to preserve itself.

“It’s the last secret of the 1967 war,” said Avner Cohen, a leading scholar of
Israel’s nuclear history who conducted the interviews. Yaakov, who oversaw
weapons development for the Israeli military, detailed the plan to Cohen in
1999 and 2000, years before he died in 2013 at 87.

“Look, it was so natural,” said Yaakov, according to a transcription of a taped
interview. “You’ve got an enemy, and he says he’s going to throw you to the
sea. You believe him.”

“How can you stop him?” he asked. “You scare him. If you’ve got something
you can scare him with, you scare him.”

Israel has never acknowledged the existence of its nuclear arsenal, in an
effort to preserve “nuclear ambiguity” and forestall periodic calls for a
nuclear-free Middle East. In 2001, Yaakov was arrested, aged 75, on charges
that he had imperiled the country’s security by talking about the nuclear
programme to an Israeli reporter, whose work was censored. At various
moments, US officials, including former president Jimmy Carter long after he
left office, have acknowledged the existence of the Israeli programme,
though they have never given details.

A spokesman for the Israeli embassy in Washington said the Israeli
government would not comment on Yaakov’s role.


If the Israeli leadership had detonated the atomic device, it would have been
the first nuclear explosion used for military purposes since the US attacks on
Hiroshima and Nagasaki 22 years earlier.

The plan had a precedent: the US considered the same thing during the
Manhattan Project, as the programme’s scientists hotly debated whether to
set off a blast near Japan in an effort to scare Emperor Hirohito into a quick
surrender. The military vetoed the idea, convinced that it would not be
enough to end the war.


According to Yaakov, the Israeli plan was code-named Shimshon, or Samson,
after the biblical hero of immense strength. Israel’s nuclear deterrence
strategy has long been called the “Samson option” because Samson brought
down the roof of a Philistine temple, killing his enemies and himself. Yaakov
said he feared that if Israel, as a last resort, went ahead with the
demonstration nuclear blast in Egyptian territory, it could have killed him and
his commando team.

Cohen, a professor at the Middlebury Institute of International Studies at
Monterey and the author of Israel and the Bomb and The Worst-Kept Secret,
described the idea behind the atomic demonstration as giving “the prime
minister an ultimate option if everything else failed”. Cohen, who was born in
Israel and educated in part in the US, has pushed the frontiers of public
discourse on a fiercely hidden subject: how Israel became an
unacknowledged nuclear power in the 1960s.

On Monday, the Nuclear Proliferation International History Project of the
Woodrow Wilson International Centre for Scholars in Washington — where
Cohen is a global fellow — released on a special website a series of
documents related to the atomic plan. The project maintains a digital archive
of his work known as the Avner Cohen Collection. (President Donald Trump’s
proposed budget calls for the elimination of all federal funding for the centre,
which Congress created as a living memorial to Wilson.)

It has long been known that Israel, fearful for its existence, rushed to
complete its first atomic device on the eve of the Arab-Israeli war. But the
planned demonstration remained secret in a country where it is taboo to
discuss even half-century-old nuclear plans, and where fears persist that Iran
will eventually obtain a nuclear weapon, despite its deal with world powers.

Itzhak Yaakov never fully recovered from his legal ordeal
Shimon Peres, the former Israeli president and prime minister who died last
year, hinted at the plan’s existence in his memoirs. He referred to an
unnamed proposal that “would have deterred the Arabs and prevented the
war”.

At the time of the 1967 war, the world’s main nuclear powers were observing
an accord known as the Partial Test Ban Treaty. To curb radiation hazards, it
prohibited all test detonations of nuclear arms except for those conducted
underground. That Israel considered an open explosion was a measure of its
desperation.

“The goal,” Yaakov says on the transcribed tape, “was to create a new
situation on the ground, a situation which would force the great powers to
intervene, or a situation which would force the Egyptians to stop and say,
‘Wait a minute, we didn’t prepare for that.’ The objective was to change the
picture.”

Cohen said he struck up a relationship with Yaakov after he published Israel
and the Bomb in 1998. He interviewed him for hours in the summer and
autumn of 1999 and in early 2000, always in Hebrew and mainly in midtown
Manhattan, where the former general lived.

Those interviews paint a picture of Israel’s recognition in the early 1960s that
it needed a crash programme to get the bomb. In 1963, Yaakov, a freshly
minted colonel with engineering degrees from the Massachusetts Institute of
Technology and from Technion, the Israel Institute of Technology, became
the senior liaison officer between the Israel Defence Forces and the country’s
civilian defence units, including the project to make an atomic bomb.

As Yaakov recounted the story, in May 1967, as tensions rose with Egypt over
its decision to close the Straits of Tiran between the Gulf of Aqaba and the
Red Sea, he was half a world away, visiting the Rand Corp, in California. He
was suddenly summoned back to Israel. With it clear that war was imminent,
Yaakov said, he initiated, drafted and promoted a plan aimed at detonating a
nuclear device in the sparsely populated Eastern Sinai Desert in a display of
force.

The site chosen for the proposed explosion was a mountain top about 12
miles from an Egyptian military complex at Abu Ageila, a critical crossroads
where, on June 5, Ariel Sharon commanded Israeli troops in a battle against
the Egyptians. (Sharon later became prime minister, and died in 2014.)

The plan, if activated by order of the prime minister and military chief of staff,
was to send a small paratrooper force to divert the Egyptian army in the
desert area so that a team could lay preparations for the atomic blast. Two
large helicopters were to land, deliver the nuclear device, and then create a
command post in a mountain creek or canyon. If the order came to detonate,
the blinding flash and mushroom cloud would have been seen throughout
the Sinai and Negev deserts, and perhaps as far away as Cairo.

Yaakov described a helicopter reconnaissance flight he made with Israel
Dostrovsky, the first director general of the Israel Atomic Energy
Commission, the civilian arm of the bomb programme. The helicopter had to
turn back after the pilots learnt that Egyptian jets were taking off, perhaps to
intercept them. “We got very close,” Yaakov recalled. “We saw the mountain,
and we saw that there is a place to hide there, in some canyon.”

On the eve of the war, Yaakov said, he was filled with the same doubts that
had gnawed at the American scientists during the Manhattan Project. Would
the bomb explode? Would he survive the blast? He never got to find out.
Israel defeated three Arab armies, gained territory four times its original size
and became the region’s foremost military power using conventional arms.

Nonetheless, Yaakov continued to lobby for an atomic demonstration to
make clear the country’s new status as a nuclear power. But the idea went
nowhere. “I still think to this day that we should have done it,” he told Cohen.

During a visit to Israel, a year after telling his story to Cohen in New York,
where he had worked as a venture capitalist after having played a key role in
the founding of Israel’s technology industry, Yaakov was arrested on charges
of “high espionage” that carried a maximum penalty of life behind bars. The
exact charges were a mystery, and he was put on a secret trial.

“We see this as a very sad story of a person who dedicates his life to the
security of Israel and ends up caught in a huge story that gets blown out of
proportion and jeopardises his reputation, his career, his legacy, everything,”
Jack Chen, one of his lawyers, told The New York Times at the time.

It turned out that the charges centred on his conversations with an Israeli
reporter, whose account of the 1967 plan was censored by the military.
Yaakov was found guilty of handing over secret information without
authorisation, the lesser of the charges against him. He was given a two-year
suspended sentence.

The Israeli newspaper Haaretz, in its obituary of Yaakov, said he had never
fully recovered from his legal ordeal and, during his final days, bitterly
discussed its details with fellow retired officers.

Cohen said he and Yaakov continued to get together long after the interviews
and the secret trial — for instance, in a restaurant in Tel Aviv around 2009. He
said he had promised Yaakov he would find the right time and the right place
to make his story public. Now, he said, on the 50th anniversary of the war —
with Yaakov and so many other witnesses long dead — it seemed like the
right time.

Nuclear Notebook: Israeli nuclear weapons
By Hans M. Kristensen, Matt Korda | January 17, 2022

The Nuclear Notebook is researched and written by Hans M. Kristensen,
director of the Nuclear Information Project with the Federation of American
Scientists, and Matt Korda, a senior research associate with the project. The
Nuclear Notebook column has been published in the Bulletin of the Atomic
Scientists since 1987. This issue’s column examines Israel’s nuclear arsenal,
which we estimate includes a stockpile of roughly 90 warheads. Israel neither
officially confirms nor denies that it possesses nuclear weapons, and our
estimate is therefore largely based on calculations of Israel’s stockpile of
weapon-grade plutonium and its inventory of operational nuclear-capable
delivery systems.

Conducting research on Israeli nuclear weapons has historically been very
challenging, not least because Israel purposely does not acknowledge its
own possession of nuclear weapons. Moreover, Western governments
normally do not include Israel in their descriptions of nuclear-armed states.
Additionally, Israeli nuclear whistleblowers have faced significant penalties; in
1986, former nuclear technician Mordechai Vanunu was kidnapped by Israeli
intelligence services and spent 18 years in prison after giving a detailed
interview about Israel’s nuclear program to the Sunday Times (Myre 2004).
This chilling effect means that individuals with knowledge of Israel’s nuclear
program have been understandably reluctant to provide on-the-record
information, which dilutes the ability of open-source researchers to analyze
Israel’s nuclear forces. Thankfully, over the past two decades, historians like
Avner Cohen and William Burr have contributed invaluable research that has
made previously unknown nuances of Israel’s opaque nuclear policy available
to the public.1

Additionally, since 1997 a US law known as the Kyl-Bingaman Amendment
has prohibited US companies from publishing satellite imagery at a resolution
that is “no more detailed or precise than satellite imagery of Israel that is
available from commercial sources.” For decades, this has meant that the
majority of commercially available satellite imagery of Israel has been limited
to a resolution of approximately two meters, making it very difficult to analyze
in detail. However, in June 2020, the US Commercial Remote Sensing
Regulatory Affairs Office announced that it would now allow commercial
imagery providers to offer enhanced imagery of Israel at a resolution of 0.4
meters (National Oceanic and Atmospheric Administration 2020). The move
was made in order to bring American imagery providers in line with their
foreign counterparts, which had already been producing imagery at that level
for several years. As a result, we have incorporated higher-resolution imagery
into this article.

The history of Israel’s nuclear program

The Israeli nuclear weapons program dates back to the mid-1950s, when the
country’s first prime minister, David Ben Gurion, began to explore a nuclear
insurance plan in order to offset the combined conventional superiority of
Israel’s neighboring Arab states. As historian Avner Cohen writes, “Ben
Gurion’s determination to launch the nuclear project was the result of
strategic intuition and obsessive fears, not of a well-thought-out plan. He
believed Israel needed nuclear weapons as insurance if it could no longer
compete with the Arabs in an arms race and as a weapon of last resort in
case of an extreme military emergency” (Cohen 1998). Ben Gurion tapped
Shimon Peres––who would later become Israel’s prime minister––to lead
Israel’s nuclear program. Under Peres’ stewardship, Israel purchased a
substantial package, including a research reactor and plutonium separation
technology, from France in 1957, as well as 20 tons of heavy water from
Norway in 1959 (Cohen and Burr 2015). The ground for the Negev Nuclear
Research Center was broken near Dimona in early 1958.

Although the Negev center was always intended for the development of
nuclear weapons, the United States did not become aware of its true
purpose for another decade, even after US intelligence became aware of its
construction in 1958 (Cohen and Burr 2021). This was largely due to a highly
successful Israeli deception and disinformation campaign aimed at
convincing US inspectors that the complex was for civilian use. The
deception campaign included lying to US officials by first telling them that
the Negev center was the site of a textile factory. Next, they said that the
Negev center was instead a purely civilian research center that did not
contain the chemical reprocessing plant it would need to produce nuclear
weapons (Cohen and Burr 2015). Investigative journalist Seymour Hersh’s
book, The Samson Option, includes a short description of the Israeli
deception scheme:

“A false control room was constructed at Dimona, complete with false
control panels and computer-driven measuring devices that seemed to be
gauging the thermal output of a twenty-four-megawatt reactor (as Israel
claimed Dimona to be) in full operation. There were extensive practice
sessions in the fake control room, as Israeli technicians sought to avoid any
slips when the Americans arrived. The goal was to convince the inspectors
that no chemical reprocessing plant existed or was possible” (Hersh 1991).

production reactor at the Negev Nuclear Research Center near Dimona.

Several factors appear to have contributed to the United States’
susceptibility to the Israeli deception campaign. Given Israel’s strong
resistance to a formalized inspection protocol, the United States declined to
pressure Israel to commit to one, instead acquiescing to Israel’s preference
to consider the arrangement as “scientific visits” instead of “inspections.”

Additionally, declassified documents suggest that the United States was
unaware of the degree of Franco-Israeli cooperation, and particularly the
Negev center package’s inclusion of a large underground chemical
reprocessing plant for extracting weapons-grade plutonium. At the time,
American intelligence incorrectly believed that it would be able to detect this
critical facility’s construction through on-site visits; however, without an
agreed framework for comprehensive inspections, US visiting scientists were
ill-equipped to assess the complete scope of the construction efforts at
Negev. Additionally, as Avner Cohen suggests, the visiting scientists’ mission
“was not to challenge what they were told, but to verify it” (Cohen 1998,
107). As a result, they were unaware––and perhaps unwilling to consider the
possibility––that a six-story underground reprocessing facility was being
built right under their noses (Cohen and Burr 2021).

The construction of the chemical reprocessing plant was reportedly
completed in 1965, and Israel began plutonium production in 1966 (Cohen
and Burr 2020). It remains unclear exactly when Israel’s first operational
nuclear weapons were completed, although it is believed that Israel may have
assembled––or attempted to assemble––its first crude nuclear devices
during the May 1967 crisis immediately preceding the Six-Day War.

Nuclear ambiguity

Since the late 1960s, every Israeli government has practiced a policy of
nuclear ambiguity. “Amimut,” as it is known, deliberately obscures whether
Israel actually possesses nuclear weapons, and if so, how its arsenal is
operationalized. Since the mid-1960s, this policy has been publicly
expressed—and recently reaffirmed by former prime minister Benjamin
Netanyahu—as the phrase “We won’t be the first to introduce nuclear
weapons into the Middle East” (Netanyahu 2011).

The Israeli government’s interpretation of “introducing” nuclear weapons,
however, appears to have so many caveats that the statement itself is
rendered essentially meaningless. This is because Israeli policymakers have
previously suggested that “introducing” nuclear weapons would necessarily
require Israel to test, publicly declare, or actually use its nuclear capability.
Given that Israel has not officially done any of those things, the Israeli
government can declare that it has not “introduced” nuclear weapons into
the region, despite the high likelihood that in reality the country possesses a
sizable nuclear arsenal.

Israel’s policy of deliberate ambiguity was enshrined during the country’s
negotiations with the United States over the purchase of 50 F-4 Phantom
aircraft during the late 1960s. The United States’ and Israel’s competing
interpretations over the term “introduce” threatened to derail the arms sale
entirely. In a July 1969 memorandum addressed to President Nixon, Henry
Kissinger noted that “We and Israel differ on what ‘introducing’ nuclear
weapons means. Ambassador Rabin believes only testing and making public
the fact of possession constitute ‘introduction.’ We stated in the exchange of
letters confirming the Phantom sale that we consider ‘physical possession
and control of nuclear arms’ to constitute ‘introduction” (US State
Department 1969a).

During a meeting at the Pentagon in November 1968, Israel’s ambassador to
the United States, Yitzhak Rabin––who later succeeded Prime Minister Golda
Meir as Israeli prime minister––said that “he would not consider a weapon
that had not been tested to be a weapon.” Moreover, he said, “There must be
a public acknowledgement. The fact that you have got it must be known.”
Seeking clarity, US Assistant Secretary of Defense Paul Warnke asked: “Then
in your view, an unadvertised, untested nuclear device is not a nuclear
weapon?” Rabin responded: “Yes, that is correct.” So, Warnke continued, an
advertised but untested device or weapon would constitute introduction?
“Yes, that would be introduction,” Rabin confirmed (US Defense Department
1968, 2, 3, 4).

In a follow-up exchange in July 1969, the Nixon administration plainly
summarized its own understanding of the term “introduction:” “When Israel
says it will not introduce nuclear weapons it means it will not possess such
weapons.” The Nixon administration wanted Israel to accept the US
definition, but the Meir government didn’t take the bait and instead claimed:
“Introduction means the transformation from a non-nuclear weapon country
into a nuclear weapon country” (US State Department 1969a). In other
words, Israel construed its pledge not to be the first to introduce nuclear
weapons to mean that that introduction was not about physical possession
but about public acknowledgement of that possession.

Kissinger saw a way out of the disagreement: He informed President Nixon
that the Israelis had defined the word “introduction” by “relating it to the NPT
[Nuclear Non-Proliferation Treaty].” Kissinger’s argument was that the
“distinction between ‘nuclear-weapon’ and ‘non-nuclear-weapon’ states is
the one which the NPT uses in defining the respective obligations of the
signatories.” He argued that the NPT negotiations “implicitly left … it up to
the conscience of the governments involved” by being “deliberately vague on
what precise step would transform a state into a nuclear weapon state after
the January 1, 1967 cut-off date used in the treaty to define the nuclear
states” (White House 1969b, 1). Kissinger also argued that the NPT does not
define what it means to “manufacture” or “acquire” nuclear weapons and
concluded that the new Israeli formulation “should put us in a position for the
record of being able to say we assume we have Israel’s assurance that it will
remain a non-nuclear state as defined in the NPT” (White House 1969b, 1).

Kissinger’s circuitous interpretation provided the United States with a way
out of a diplomatic dilemma via a tacit understanding between Nixon and
Meir. That is, the United States would no longer pressure Israel to sign the
Nuclear Non-Proliferation Treaty as long as the Israelis kept their program
restrained and invisible—meaning that Israel would not test nuclear weapons
and would not acknowledge in public its possession of such weapons.

The goal of this interpretation, stated a July 1969 memo, was to break the
diplomatic deadlock while avoiding direct complicity in Israel’s nuclear
program, which would have contradicted the United States’ own non-
proliferation policies. Specifically, the memo noted that the United States
“cannot enforce a precise understanding” of what “introduction” means.
Instead, the policy should be to “mainly concern ourselves with building a
record that will permit us to defend taking our distance from a nuclear Israel
if ever Israel’s use of those weapons threatens to involve us in nuclear
confrontation” (White House 1969d). Despite this attempt to distance itself
from Israel’s nuclear program, the United States’ clear willingness to turn a
blind eye to Israeli proliferation is a double standard that has largely
undermined its own credibility when criticizing the nuclear pursuits of other
Middle Eastern countries.

After the end of the Cold War, Israel began to fear that the United States’
tacit support for Israel’s undeclared nuclear arsenal would soon fade, given
US engagement on a possible Middle East nuclear-weapon free zone. As a
result, Israel has reportedly requested that each American president since
Bill Clinton sign a letter indicating that any future US arms control efforts
would not affect Israel’s nuclear arsenal (Entous 2018a; Entous 2018b).

On a few rare occasions, some Israeli officials have made statements
implying that Israel already has nuclear weapons or could “introduce” them
very quickly if necessary. The first came in 1974, when then-President
Ephraim Katzir stated: “It has always been our intention to develop a nuclear
potential … We now have that potential” (Weissman and Krosney 1981, 105).
Long after his retirement, in a 1981 New York Times interview, former
defense minister Moshe Dayan also came close to violating the nuclear
ambiguity taboo when he declared for the record: “We don’t have any atomic
bomb now, but we have the capacity, we can do that in a short time.” He
reiterated the official policy mantra: “We are not going to be the first ones to
introduce nuclear weapons into the Middle East” (New York Times 1981). But
his acknowledgement that “we have the capacity” and would quickly
produce atomic bombs if Israel’s adversaries acquired nuclear weapons was
a hint that Israel had in fact produced all the necessary components to
assemble nuclear weapons in a very short time (New York Times 1981).

During a press conference in Washington with US President Bill Clinton and
Jordan’s President Hussein in 1994, Israeli Prime Minister Yitzhak Rabin
made a similar statement, saying “Israel is not a nuclear country in terms of
weapons” and has “committed to the United States for many years not to be
the first to introduce nuclear weapons in the context of the Arab-Israeli
conflict. But at the same time,” he added, “we cannot be blind to efforts that
are made in certain Muslim and Arab countries in this direction. Therefore, I
can sum up. We’ll keep our commitment not to be the first to introduce, but
we still look ahead to the dangers that others will do it. And we have to be
prepared for it” (Rabin 1994; emphasis added).

The ambiguity left by Israel’s refusal to confirm or deny the possession of
nuclear weapons prompted the BBC in 2003 to bluntly ask former Prime
Minister Shimon Peres: “The term nuclear ambiguity, in some ways it sounds
very grand, but isn’t it just a euphemism for deception?” Peres did not
answer the question but confirmed the need for deception: “If someone
wants to kill you and you use deception to save your life, it’s not immoral. If
we wouldn’t [sic] have enemies we wouldn’t need deceptions” (BBC 2003).

Three years later, in a December 2006 interview with German television,
then-prime minister Ehud Olmert appeared to compromise the deception
when he criticized Iran for aspiring “to have nuclear weapons, as America,
France, Israel, Russia” (Williams 2006). The statement, which he made in
English, attracted widespread attention because it was seen as an
inadvertent admission that Israel possesses nuclear weapons (Williams
2006). A spokesperson for Olmert later said he had been listing not nuclear
states but “responsible nations” (Friedman 2006).

Ambiguity is not just about refusing to confirm possession of nuclear
weapons but also about refusing to deny it. When asked during a 2011 CNN
interview if Israel does not have nuclear weapons, Netanyahu did not answer
directly but repeated the policy not to be the first to “introduce” nuclear
weapons into the Middle East. Undeterred, the journalist followed up: “But if
you take an assumption that other countries have them then that may mean
you have them?” Netanyahu didn’t dispute that but implied that the
difference is that Israel doesn’t threaten anyone with its arsenal: “Well, it may
mean that we don’t pose a threat to anyone. We don’t call for anyone’s
annihilation … We don’t threaten to obliterate countries with nuclear weapons
but we are threatened with all these threats” (Netanyahu 2011).

Three cases of near-introduction

There have been three distinct incidents during which Israel reportedly came
close to “introducing” nuclear weapons to the region, under its own narrow
definition. The first instance was during the Six-Day War in June 1967, when
according to primary sources and testimonies from former Israeli officials, a
small team of commandos was tasked with conducting Operation “Shimson”
(Samson)––a planned nuclear detonation for demonstrative purposes––in
order to change the Arab coalition’s military calculus. Given Israel’s eventual
military success in the war, this plan was never put into action (Cohen 2017).

The second instance reportedly came during the October 1973 Yom Kippur
War, when Israeli leaders feared that Syria was about to defeat the Israeli
army in the Golan Heights. The rumor first appeared in Time magazine in
1976, was greatly expanded upon in Seymour Hersh’s book The Samson
Option in 1991, and several unidentified former US officials allegedly stated in
2002 that Israel put nuclear forces on alert in 1973 (see e.g., Sale 2002).

However, an interview conducted by Avner Cohen with the late Arnan (Sini)
Azaryahu in January 2008 calls into question the validity of this rumor.
Azaryahu was senior aide and confidant to Yisrael Galili, a minister without
portfolio who was Golda Meir’s closest political ally and privy to some of
Israel’s most closely held nuclear secrets. In the early afternoon of the
second day of the war—October 7, 1973—the Israeli military appeared to be
losing the battle against Syrian forces in the Golan Heights. Azaryahu said
that the defense minister, Moshe Dayan, asked Meir to authorize initial
technical preparations for a “demonstration option”—that is, to ready nuclear
weapons for potential use. But Galili and Deputy Prime Minister Yigal Allon
argued against the idea, saying Israel would prevail using conventional
weapons. According to Azaryahu, Meir sided with her two senior ministers
and told Dayan to “forget it” (Cohen 2013). (For analysis of the Azaryahu
interview and its implications, see Cohen 2008.)

A study by the Strategic Studies division of the Center for Naval Analyses in
April 2013 appeared to confirm Meir’s rejection of Dayan’s “demonstration
option” and that Israel’s nuclear forces were not readied. The report states
that the authors “did exhaustively scrutinize” the document files of US
agencies and archives and interviewed a significant number of officials with
firsthand knowledge of the 1973 crisis. Still, it also notes that “(n)one of
these searches revealed any documentation of an Israeli alert or clear
manipulation of its forces,” and “none of our interviewees, save one, recalled
any Israeli nuclear alert or signaling effort” during the Yom Kippur War (Colby
et al. 2013, 31–32).

Even so, a single former official recalled seeing an “electronic or signals
intelligence report” at the time that “Israel had activated or increased the
readiness of its Jericho missile batteries.” That, together with the extreme
government secrecy that surrounds Israeli nuclear weapons in general, led
the authors of the Center for Naval Analyses study to conclude that “the
United States did observe some kind of Israeli nuclear weapons-related
activity in the very early days of the war, probably pertaining to Israel’s
Jericho ballistic missile force … .” (Colby et al. 2013, 34). The study’s overall
assessment was that “Israel appears to have taken preliminary precautionary
steps to protect or prepare its nuclear weapons and/or related forces” (Colby
et al. 2013, 2; emphasis added).

The conclusion that Israel did something with its nuclear forces in October
1973—although not necessarily place them on full operational alert or
prepare for a “demonstration option”—seems similar to the assertion made
by Peres in 1995. In an interview with the authors of We All Lost the Cold War,
Peres “categorically denied that Jericho missiles were made ready, much less
armed. At most, he insisted, there was an operational check. The cabinet
never approved any alert of Jericho missiles” (Lebow and Stein 1995, 463,
footnote 47).

Evidently, some uncertainty persists about the 1973 events. But then,
presumably as well as now, the Israeli warheads were not fully assembled or
deployed on delivery systems under normal circumstances but stored under
civilian control. And since no official confirmation was made back then either
via a test or an announcement, no formal “introduction” of nuclear weapons
occurred—at least in the opinion of Israeli officials.

The third potential instance of near-introduction came six years later, on
September 22, 1979, when a US surveillance satellite known as the Vela 6911
detected what appeared to be a double-flash from a nuclear test in the
southern parts of the Indian Ocean. (For background on the 1979 Vela
incident, see Richelson 2006; Cohen and Burr 2016.) Declassified US
intelligence documents indicate the prevailing US belief at the time that the
flash was the result of an Israeli nuclear test, possibly with South African
logistical support. A subsequent 1980 White House panel concluded that the
the Vela signal “was probably not from a nuclear event.” However, US
scientists and intelligence analysts, who believed that the panel’s
conclusions had been heavily biased in order to avoid a political
confrontation with Israel, widely rejected these conclusions, according to
newly declassified documents. Additionally, the documents appear to
suggest that Israeli sources leaked confirmations about the nuclear test to
US officials and journalists, but that these claims were either censored or not
taken seriously (Cohen and Burr 2016). If the Vela incident was indeed an
Israeli nuclear test, it is unclear whether it would constitute the “introduction”
of nuclear weapons under Israel’s narrow definition. That is, according to
Yitzhak Rabin at the time of the negotiations in the late 1960s, “There must
be a public acknowledgement. The fact that you have got it must be known”
(US Defense Department 1968). Successive Israeli governments have never
publicly acknowledged Israel’s involvement in the Vela incident.

Stockpile size and warhead composition

Absent official public information from the Israeli government or intelligence
communities of other countries, speculations abound about Israel’s nuclear
arsenal. Over the past several decades, news media reports, think tanks,
authors, and analysts have presented a wide range of possibilities for the size
of the Israeli nuclear stockpile, from 75 warheads to more than 400
warheads. Delivery vehicles for the warheads have been listed as aircraft,
ballistic missiles, artillery tactical or battlefield weapons such as artillery
shells and landmines, and more recently sea-launched cruise missiles.2 We
believe that many of these rumors are inaccurate and that the most credible
stockpile number is less than one hundred warheads, probably on the order
of 90 warheads for delivery by aircraft, land-based ballistic missiles, and
possibly sea-based cruise missiles (see Table 1).

Table 1: Israeli nuclear weapons, 2021
The design and sophistication level of Israel’s nuclear weapons is up for
considerable debate. Frank Barnaby, a nuclear physicist who worked at the
British Atomic Weapons Research Establishment, interviewed whistleblower
and former nuclear technician Mordechai Vanunu in 1986. Barnaby later said
that Vanunu’s description of “production at Dimona of lithium-deuteride in
the shape of hemispherical shells … raised the question of whether Israel had
boosted nuclear weapons in its arsenal” (Barnaby 2004, 4). Although he
didn’t think Vanunu had much knowledge about such weapons, Barnaby
concluded that “the information he gave suggested that Israel had more
advanced nuclear weapons than Nagasaki-type weapons” (Barnaby 2004,
4).

Barnaby did not mention thermonuclear weapons in his 2004 statement,
even though he concluded in his book The Invisible Bomb in 1989 that “Israel
may have about 35 thermonuclear weapons” (Barnaby 1989, 25). At the
time, the director of the CIA apparently did not agree but reportedly
indicated that Israel may be seeking to construct a thermonuclear weapon
(Cordesman 2005). Yet The Samson Option claims that US weapon
designers concluded from Vanunu’s information that “Israel was capable of
manufacturing one of the most sophisticated weapons in the nuclear arsenal
—a low-yield [two-stage] neutron bomb” (Hersh 1991, 199). The authors of
The Nuclear Express in 2009 echoed that claim, stating that the product of
Israel’s partnership with South Africa would be “a family of boosted
primaries, generic H-bombs, and a specific neutron bomb” (Reed and
Stillman 2009, 174).

On the other hand, an April 1987 report by the Institute for Defense Analyses
concluded––following a trip to Israel’s Soreq Nuclear Research Center––that
Israel lacked the computational sophistication to develop the “codes which
detail fission and fusion processes on a microscopic and macroscopic level,”
which would be necessary for the development of thermonuclear weapons
(Townsley and Robinson 1987).

If Israel was indeed behind the 1979 Vela incident, the country would have
conducted only one known atmospheric nuclear test; this could indicate that
Israel’s nuclear weapons designs are not particularly sophisticated. It took
other nuclear weapon states dozens of elaborate nuclear test explosion
experiments to develop sophisticated weapon designs. According to some
analysts, however, Israel had “unrestricted access to French nuclear test
explosion data” in the 1960s (Cohen 1998, 82–83), so much so that “the
French nuclear test in 1960 made two nuclear powers not one” (Weissman
and Krosney 1981, 114–117). Until France broke off deep nuclear
collaboration with Israel in 1967, France conducted 17 fission warhead tests
in Algeria, ranging from a few kilotons to approximately 120 kilotons of
explosive yield (CTBTO(n.d.); Nuclear Weapon Archive 2001). France did not
conduct its first two-stage thermonuclear test until August 1968.

In sum, it remains highly challenging to assess Israel’s design sophistication
for its nuclear weapons. It is hypothetically possible that Israel developed
two-stage thermonuclear weapons. Yet a more cautious analysis based upon
Israel’s plutonium production, testing history, design skills, force structure,
and employment strategy suggests that its arsenal probably consists of
single-stage, boosted fission warheads.

Most publicly available estimates of the number of Israeli warheads in its
stockpile appear to be derived from a rough calculation of the number of
warheads that could hypothetically be created from the amount of plutonium
Israel is believed to have produced in its nuclear reactor at Dimona. The
technical assessment that accompanied the 1986 Sunday Times article
about former nuclear technician Mordechai Vanunu’s disclosures, for
example, estimated that Israel had produced enough plutonium for 100 to
200 nuclear warheads (Sunday Times 1986a, 1986b, 1986c).3 In the public
debate, this quickly became Israel possessing 100 to 200 nuclear warheads,
the estimate that has been most commonly used ever since. Analysts are
uncertain about the operational history or efficiency of the Dimona reactor’s
operation over the years, but plutonium production is thought to have
continued after 1986. The International Panel on Fissile Materials estimates
that as of the beginning of 2020, Israel may have a stockpile of about 980 ±
130 kilograms of plutonium (International Panel on Fissile Materials 2021).
That amount could potentially be used to build anywhere between 170 and
278 nuclear weapons, assuming a second-generation, single-stage, fission-
implosion warhead design with a boosted pit containing 4 to 5 kilograms of
plutonium.4

Total plutonium production is a misleading indicator of the actual size of the
Israeli nuclear arsenal, however, because Israel—like other nuclear-armed
states—most likely would not have converted all of its plutonium into
warheads; a portion is likely stored as a strategic reserve. Additionally, the
total number of deliverable warheads would presumably be tied to Israel’s
limited number of aircraft and missiles that are equipped to deliver nuclear
weapons, as well as to the limited number of targets that Israel would seek to
strike in a conflict. As a result, estimates of the Israeli nuclear stockpile
numbering in the hundreds of warheads may be exaggerated.

US government assessments offer more conservative estimates of Israel’s
nuclear arsenal. A classified 1999 Defense Intelligence Agency report leaked
in 2004 described Israel’s nuclear arsenal as numbering between 60 and 80
warheads in 1999, with the potential to grow to between 65 and 85
warheads by 2020 (Defense Intelligence Agency 1999).5 In a similar vein, in
1998 a RAND Corporation study commissioned by the Pentagon concluded
that Israel had enough plutonium to build 70 nuclear weapons (Schmemann
1998).

During the two decades that have passed since the DIA report, Israel
presumably has continued the production of plutonium at Dimona for some
of that time. Given Israel’s presumed surplus of plutonium at this stage, the
Dimona reactor’s current primary role is likely producing tritium, in order to
replenish the material as it decays. The Dimona complex has probably also
continued producing nuclear warheads. Many of those warheads were
probably replacements for warheads produced earlier for existing delivery
systems, such as the Jericho II missiles and aircraft. Warheads for a rumored
Jericho III ballistic missile would probably replace existing Jericho II
warheads on a one-for-one basis. Warheads for the rumored submarine-
based cruise missile, if true, would be in addition to the existing arsenal but
probably only involve a relatively small number of warheads.

The reactor at Dimona is nearing the end of its useful design life, and the
condition of the aluminum reactor pressure vessel––which cannot be
replaced as part of a life-extension project––is believed to be deteriorating.
Nevertheless, Israeli officials have indicated that they intend to keep the
reactor operating until 2040 (Kelley and Dewey 2018). Satellite photos from
February 2021 indicate that Dimona is currently undergoing its largest
construction project in decades, with a large dig several stories deep located
near the reactor (Gambrell 2021). It is unclear whether this new construction
is related to Dimona’s life-extension campaign. Eventually, the Dimona
reactor will need to be replaced; however, Israel’s non-party status to the
Non-Proliferation Treaty means that it may face challenges purchasing a
replacement reactor from another country. This is because it would
theoretically be subject to strict export controls by the Nuclear Suppliers
Group (Kelley and Dewey 2018).

Nuclear-capable aircraft

Since the 1980s, the F-16 has been the backbone of the Israeli Air Force.
Over the years, Israel has purchased well over 200 F-16s of all types, as well
as specially configured F-16Is. Various versions of the F-16 serve nuclear
strike roles in the US Air Force and among NATO allies, and the F-16 is the
most likely candidate for air delivery of Israeli nuclear weapons at the present
time.

Since 1998, Israel has also used its 25 Boeing F-15E Strike Eagles for long-
range strike and air-superiority roles. The Israeli version, known as the F-15I
(or “Baz”), is characterized by greater takeoff weight—36,750 kilograms—
and range—4,450 kilometers—than other F-15 models. Its maximum speed
at high altitude is Mach 2.5. The plane has been further modified with
specialized radar that has terrain-mapping capability and other navigation
and guidance systems. In the US Air Force, the F-15E Strike Eagle has been
given a nuclear role. It is not known if the Israeli Air Force has added nuclear
capability to this highly versatile plane, but when Israel sent half a dozen F-
15Is from Tel Nof air base to the United Kingdom in September 2019, a US
official privately commented that Israel had sent its nuclear squadron
(Kristensen 2019).

Israel has recently purchased 50 F-35s from the United States, becoming
the first non-US country to operate the aircraft. The Israeli version of the
aircraft––which will include indigenously designed electronic warfare suites,
guided bombs, and air-to-air missiles––is known as the F-35I (named “Adir”
for “awesome” or “mighty”). As of September 2021, Israel has received 30 F-
35Is, operating them in three squadrons from Nevatim Air Base: the 140th
(“Golden Eagle”) squadron, the Israeli Air Force’s first squadron of F-35s; the
116th (“Lions of the South”) squadron; and the 117th (“First Jet”) squadron,
the latter of which is currently operating only as a training squadron. The
remaining 20 F-25s are scheduled to be delivered by 2024 (Gross 2021;
Pansky 2020). The F-35 squadrons are gradually replacing the aging F-16s;
the 117th squadron was deactivated in October 2020 in order to swap out its
F-16C/D aircraft with the requisite F-35 training systems (Gross 2020). The
US Air Force is upgrading its F-35As to carry nuclear bombs, and Israel’s
Channel 2 reported that an unnamed “senior level US official” refused to say
if Israel had requested such an upgrade for its F-35s (Channel 12 2014).

It is especially difficult to determine which Israeli wings and squadrons are
assigned nuclear missions and which bases support them. The nuclear
warheads themselves may be stored in underground facilities near one or
two bases. Israeli F-16 squadrons are based at Ramat David Air Base in
northern Israel; Tel Nof and Hatzor air bases in central Israel; and Hatzerim,
Ramon, and Ovda air bases in southern Israel. Of the many F-16 squadrons,
only a small fraction—perhaps one or two—would actually be nuclear-
certified with specially trained crews, unique procedures, and modified
aircraft. The F-15s are based at Tel Nof Air Base in central Israel, and
Hatzerim Air Base in the Negev desert. We cautiously suggest that Tel Nof
Air Base in central Israel and Hatzerim Air Base in the Negev desert might
have nuclear missions.

Land-based ballistic missiles

Israel’s nuclear missile program dates back to the early 1960s. In April 1963,
several months before the Dimona reactor began producing plutonium, Israel
signed an agreement with the French company Dassault to produce a short-
range surface-to-surface ballistic missile. The missile system became known
as the Jericho (or MD-620), and the program was completed around 1970
with 24 to 30 missiles.

Most sources assert that Jericho was a mobile missile, transported and fired
from a transportable erector launcher (CIA 1974). But there have
occasionally been references to possible silos for the weapon. A US State
Department study produced in support of National Security Study
Memorandum 40 in May 1969 concluded that Israel believed it needed a
nearly invulnerable nuclear force to deter a nuclear first strike from its
enemies, “i.e., having a second-strike capability.” The study stated: “Israel is
now building such a force—the hardened silos of the Jericho missiles” (US
State Department 1969d, 7; emphasis added). It is not clear that the claim of
“hardened silos” constituted the assessment of the US intelligence
community or whether it referred to early construction of what is now
thought to be mobile launcher bunkers at Sdot Micha, and only a few
subsequent sources—all non-governmental—have mentioned Israeli missile
silos.6 We have not found any public evidence of Jericho silos.

In collaboration with South Africa, in the late 1980s Israel developed the two-
stage, solid-fuel, medium-range Jericho II that––for the first time––put the
southern-most Soviet cities and the Black Sea Fleet within range. Jericho II, a
modified version of the Shavit space launch rocket, was first deployed in the
early-1990s, replacing the first Jericho. The Jericho was first flight-tested in
May 1987 to approximately 850 kilometers (527 miles). The trajectory went
far into the Mediterranean Sea. Another test in September 1989 reached
1,300 kilometers (806 miles). The US Air Force National Air Intelligence
Center in 1996 reported the Jericho II range as 1,500 kilometers (930 miles)
(NAIC 1996).

Given that approximately half of Iran (including Tehran) is beyond the range
of Jericho II medium range ballistic missile, Israel is currently upgrading its
arsenal with the newer and more capable three-stage Jericho III
intermediate-range ballistic missile. The Jericho III reportedly has a range
exceeding 4,000 kilometers, which would be able to target all of Iran,
Pakistan, and all of Russia west of the Urals—including, for the first time,
Moscow. Jericho III was first test-launched over the Mediterranean Sea in
January 2008 and reportedly became operational in 2011. Unidentified
defense sources told Jane’s Defence Weekly that Jericho III constitutes “a
dramatic leap in Israel’s missile capabilities” (Jane’s Defence Weekly 2008,
5), but many details and its current status are unknown. In July 2013, Israel
tested an “improved” version of the Jericho III missile––possibly designated
the Jericho IIIA––with a new motor that some sources believe may offer the
missile an intercontinental range exceeding 5,500 kilometers (Ben David
2013a; Ben David 2013b). It is unclear whether Israel is replacing its Jericho II
missiles with Jericho IIIs on a one-for-one basis, or if they are being deployed
concurrently, although the former is more likely. Upgrades of suspected
launcher bunkers at Sdot Micha began in 2014.

In recent years, Israel has conducted several test-launches of what it calls
“rocket propulsion systems.” These tests––which have been conducted in
May 2015, May 2017, December 2019, and January 2020––are typically not
accompanied by confirmation of an official test location (Agence France-
Presse 2015; Ministry of Defense 2017; Kubovich 2019; Ministry of Defense
2020). However, local news sources and video footage indicate that the test
site is likely to be Palmachim Air Base, Israel’s Jericho missile and Shavit
space launch vehicle test site located on the Mediterranean coast (Trevithick
2019). In April 2021, video footage captured a significant blast at Sdot Micha
Air Base, which external analysts have suggested was likely to be another
rocket engine test (Lewis 2021). Unlike the previous tests, however, the
Defense Ministry did not provide a statement confirming it as such. The flurry
of rocket propulsion test activity has stirred up speculation that Israel could
be developing a newer version of its Jericho missile, possibly known as
Jericho-IV.

How many Jericho missiles Israel has is another uncertainty. Estimates vary
from 25 to 100. Most sources estimate that Israel has 50 of these missiles
and place them at the Sdot Micha facility near the town of Zakharia in the
Judean Hills, approximately 27 kilometers east of Jerusalem. (There are
many alternative spellings and names for the base, including Zekharyeh,
Zekharaia, Sdot Micha, and Sdot HaElla.)

Commercial satellite images show what appear to be two clusters of what
might be caves or bunkers for mobile Jericho launchers at Sdot Micha. The
northern cluster includes 14 caves and the southern cluster has nine caves,
for a total of 23 caves. Newly available high-resolution imagery indicates that
each cave appears to have two entrances, which suggests that each cave
can hold up to two launchers. The satellite images show that caves’
refurbishment began in 2014 and appeared complete in 2020. The upgrade
also included upgrades to several tunnels to underground facilities. If all 23
caves are full, this would amount to 46 launchers. Each cluster also has what
appears to be a covered high-bay drive-through facility, potentially for
missile handling or warhead loading. A nearby complex with its own internal
perimeter has four tunnels to underground facilities that could potentially be
for warhead storage.

Sdot Micha Figure 3: The suspected Sdot Micha Jericho nuclear missile
base includes two dozen bunkers for mobile launchers. Satellite imagery ©
2022 Maxar Technologies (image date October 8, 2021).
For the Jericho missiles to have military value, they would need to be able to
disperse from their caves. The Sdot Micha base is relatively small at 16
square kilometers, and the suspected launcher caves are located along two
roads, each of which is only about one kilometer long. This layout would
provide protection against limited conventional attacks, but it would be
vulnerable to a nuclear surprise attack. In a hypothetical crisis where the
Israeli leadership decided to activate Israel’s nuclear capability, the launchers
presumably would leave Sdot Mischa and take up positions in remote launch
areas. A US State Department background paper from 1969 stated that there
was “evidence strongly indicating that several sites providing operational
launch capabilities are virtually complete” (US State Department 1969c, 4;
emphasis added).

Sea-based missiles and submarines

Israel currently operates three German-built Dolphin-class and two Dolphin
II-class diesel-electric submarines. The Dolphin II-class submarines are
functionally identical to the Dolphin-class submarines, but with the addition
of an Air Independent Propulsion system, which alleviates the need for the
submarine to raise a snorkel to the surface to supply air to the engines and
recharge the batteries (Sutton 2017). This reportedly allows the Dolphin II-
class submarines to remain underwater for at least 18 days at a time––more
than four times longer than the Dolphin-class submarines (Der Spiegel
2012). A sixth submarine––the final submarine in the fleet of Dolphin subs––
is currently being fitted out (Shoval 2019). In 2017, the Netanyahu
government signed a memorandum of understanding with Germany to
acquire three additional Dolphin II-class submarines to replace the three
older Dolphin submarines; however, the procurement deal has been delayed
due to an ongoing corruption scandal (Opall-Rome 2017). Although Israel’s
submarines are home-ported near Haifa on the Mediterranean coast, in
recent years they have occasionally sailed through the Suez Canal, as a likely
deterrence signal to Iran (Times of Israel 2020; Times of Israel 2021).

In addition to six standard 533 millimeter torpedo tubes, Israel’s submarines
are reportedly equipped with four additional specially-designed 650
millimeter tubes (Sutton 2017). Analysts speculate that the unusual diameter
of these tubes means that they could be used to carry a sea-launched
variant of the indigenously designed “Popeye Turbo” air-to-surface missile,7
although rumors about a range over 1,000 kilometers were probably
exaggerated. The German magazine Der Spiegel reported in 2012 that the
German government had known for decades that Israel planned to equip the
submarines with nuclear missiles. Former German officials said they always
assumed Israel would use the submarines for nuclear weapons, although the
officials appeared to repeat old rumors rather than provide new information.
The article quoted another unnamed ministry official with knowledge of the
matter: “From the beginning, the boats were primarily used for the purposes
of nuclear capability” (Der Spiegel 2012).

Frank Barnaby, who cross-examined Vanunu on behalf of the Sunday Times,
stated in 2004 that the estimate for Israel’s plutonium inventory—sufficient
for “some 150 nuclear weapons”—was based on Vanunu’s description of the
reprocessing plant at Dimona (Barnaby, 2004: 3–4).
The four to five kilograms of plutonium per warhead assumes high-quality
technical and engineering performance for production facilities and
personnel. Lower performance would need a greater amount of plutonium
per warhead and therefore reduce the total number of weapons that Israel
could potentially have produced.
The secret document was leaked and reproduced in Scarborough (2004:
194–223). It is important to caution that as a Defense Intelligence Agency
document, the report does not necessarily represent the coordinated
assessment of the US intelligence community as a whole, only the view of
one part of it. An excerpt from the Defense Intelligence Agency report is
available at Kristensen and Aftergood (2007).
For an example of sources claiming Jericho missiles are deployed in silos,
see Cordesman (2008). Cordesman references the Nuclear Threat Initiative
country profile on Israeli missiles as the source for the silo claim. The NTI has
since updated its page, which no longer mentions silos. See:
