Global
nuclear stockpiles, 1945–2002
The
five major nuclear powers currently have more than 20,000 nuclear warheads
in their arsenals, as shown in the table below. But this does not include
a number of intact Russian nuclear warheads of indeterminate status—possibly
as many as 10,000. Of the more than 30,000 intact warheads belonging
to the world’s eight nuclear weapon states, the vast majority (96 percent)
are in U.S. or Russian stockpiles. About 17,500 of these warheads are
considered operational. The rest are in reserve or retired and awaiting
dismantlement.
We estimate that since 1945, more than 128,000 nuclear warheads have
been built worldwide—all but 2 percent of them by the United States
(55 percent) and the Soviet Union or Russia (43 percent). Since the
Cold War ended, more and more warheads in U.S. and Russian stockpiles
are being moved from operational status into various reserve, inactive,
or contingency categories. The destruction of warheads is not required
under current arms control agreements. For example, the 2002 Moscow
Treaty (the Strategic Offensive Reductions Treaty) contains no verification
provisions and completely ignores non-operational and non-strategic
warheads. The result is that stockpiles are more opaque and more difficult
to describe with precision.
The United States has produced some 70,000 warheads since 1945,
of which, 60,000 have been dismantled (more than 12,000 of them since
1990). The U.S. arsenal contains approximately 10,600 intact warheads.
Of this number, nearly 8,000 are considered active or operational. In
addition, several hundred warheads await disassembly at the Pantex Plant
near Amarillo, Texas, including the W56 and W79 warheads, around 36
B53 bombs, and some excess non-strategic B61 bombs. These warheads should
have been dismantled by 2000, but for various reasons, the schedule
has been extended.
As detailed in the Bush administration’s Nuclear Posture Review (NPR),
the plan is to reduce the number of “operationally deployed strategic
warheads” to 1,700– 2,200 by the end of 2012. With the possible exception
of the Minuteman III W62, there will be no further dismantlement of
warheads beyond those specified in the 1994 NPR. The reduction of operationally
deployed warheads will be accomplished by transferring warheads from
active delivery vehicles to either a “responsive force” or to “inactive
reserve.” An example of inactive reserve warheads are those that do
not have limited life components, such as tritium. Any additional disassembly
before 2014, according to the Energy Department’s National Nuclear Security
Administration, would compete with planned refurbishments of the nine
warhead types in the enduring stockpile. If current plans are fulfilled,
by 2012 we estimate that the United States will have approximately 10,000
intact warheads—essentially the same number as today.
Russia has not released information about the size of its stockpile.
We estimate that since 1949 the Soviet Union/Russia has produced about
55,000 nuclear warheads, and that about 30,000 warheads existed in 1990–1991.
The U.S. Defense Department and CIA estimate that Russia dismantled
slightly more than 1,000 warheads per year during the 1990s, so that
its remaining stockpile of intact warheads may be around 18,600. Only
around 8,600 of these are thought to be operational. As many as 10,000
nuclear warheads are believed to be in non-operational status: in reserve
for possible redeployment or retired and awaiting dismantlement.
The Moscow Treaty limits Russia’s operationally deployed strategic warheads
to no more than 2,200 by 2012, but because of limited resources and
funding, it is unlikely that Russia will be able to sustain that many.
Russia had pressed for a limit of 1,500 warheads, and if significant
numbers of warheads are not refurbished and returned to operational
forces, the stockpile could shrink to as few as 1,000 strategic warheads
and no more than 1,000 tactical warheads over the next 10 years.
Britain is estimated to have produced approximately 1,200 warheads
since 1953. Its current stockpile is thought to consist of some 200
strategic and “sub-strategic” warheads on Vanguard-class nuclear-powered
ballistic missile submarines (SSBNs). The government declared in July
1998 that there would “be fewer than 200 operationally available warheads,”
of which 48 warheads would be on patrol at any given time on a single
SSBN. The British arsenal peaked in the 1970s at 350 warheads.
France maintains approximately 350 warheads, down from 540 in
1992. France has produced more than 1,260 nuclear warheads since 1964.
It has dismantled its land-based ballistic missiles and retired its
nuclear bombs for delivery by naval-strike aircraft. The M51 sea-launched
ballistic missile scheduled for deployment in 2010 was initially slated
to carry an entirely new warhead (the TNO, or tête nucléaire océanique),
but will instead be equipped with a more robust version of an existing
design (probably the TN-75).
China is estimated to have an arsenal of around 400 nuclear warheads,
down from 435 in 1993. China is thought to have produced some 600 nuclear
warheads since 1964, and U.S. intelligence and defense agencies predict
that over the next 15 years China may increase the number of warheads
on primarily U.S-targeted missiles from 20 to between 75–100.
India and Pakistan, the world’s two newest declared nuclear
powers, have fewer than 100 nuclear warheads between them, most of which
are not yet operationally deployed. We estimate that India has produced
enough fissile material for 45–95 nuclear warheads but may have assembled
only 30–35, and that Pakistan has produced fissile material sufficient
for 30–52 weapons and assembled 24–48 warheads. Both countries are thought
to be increasing their stockpiles.
Israel has neither confirmed nor denied possession of nuclear
weapons, although U.S. intelligence reports for many years have labeled
Israel a de facto nuclear power. Some unofficial reports estimate Israel’s
arsenal to have as many as 200 warheads, the first of which reportedly
was assembled in 1967.
