The Pentagon plans to develop two "low-yield"
nuclear warheads to be launched from ballistic-missile submarines and
warships, to send a message to Moscow -- which the Trump administration
accuses of amassing a stockpile of tactical nuclear weapons.
"Expanding U.S. tailored response options will raise
the nuclear threshold and help ensure that potential adversaries
perceive no possible advantage in limited nuclear escalation, making
nuclear weapons employment less likely," the new review said.
The Pentagon says Russia’s buildup of similar "low-yield" nukes is the reason it must match the threat.
“The United States would only consider the use of
nuclear weapons in extreme circumstances,” said Deputy Defense Secretary
Patrick M. Shanahan. “Extreme circumstances could include significant
non-nuclear strategic attacks,” he added without offering specifics.
Russian and Chinese officials were briefed by State Department officials Friday morning about the nuclear posture review.
It's the first such review in seven years, but much has
changed since 2010, when the U.S. unilaterally reduced portions of its
nuclear arsenal.
“Over the past decade, while the United States led the
world in these reductions every one of our potential nuclear adversaries
has been pursuing the exact opposite strategy,” said Deputy Energy
Secretary Dan Brouillette. “These powers are increasing the numbers and
types of nuclear weapons in their arsenal.”
After Russia annexed Ukraine's Crimean Peninsula, it
deployed nuclear-capable intermediate range missiles to Kaliningrad, a
Russian enclave on the border with Poland, leaving NATO leaders feeling
helpless.
"Russia's nuclear saber-rattling is unjustified,
destabilizing and dangerous," said NATO Secretary General Jens
Stoltenberg in 2015. Any deployment of nuclear forces to Crimea would
“fundamentally change the balance of security in Europe,” he added.
Russia is bound by a decades-long arms treaty, known as
the INF, from deploying ground-launched intermediate-range missiles.
The Pentagon has accused Russia of violating the treaty, noting that
Russia is also developing nuclear depth charges, torpedoes and
anti-aircraft missiles among its 2,000 tactical nukes.
“Russia is also developing at least two new
intercontinental range systems, a hypersonic glide vehicle, and a new
intercontinental, nuclear-armed, nuclear-powered, undersea autonomous
torpedo,” according to the review.
The United States has possessed hundreds of tactical
“low-yield” nuclear warheads for decades, but they can only be delivered
from planes, including B61 gravity bombs, but are vulnerable because
the jets must fly over the target to use them making them susceptible to
anti-aircraft missiles and guns.
Currently, only the B-2 stealth bomber can penetrate sophisticated air defenses.
The Trump administration wants to build off the
previous administration’s concern that the nuclear force needs to be
modernized. It has mapped out plans for the U.S. to spend more than $1.2
trillion over the next 30 years.
In 1982, B-52 bombers were equipped with air-launched
cruise missiles, but those weapons are now “more than 25 years past its
design life,” according to the review. The newest B-52 is also more than
50 years old, one of the reasons the Pentagon wants a replacement
bomber as well replacement for the aging air-launched cruise missile.
The Air Force has 46 nuclear capable B-52H and 20 nuclear-capable B-2A stealth bombers
.
Its bomber fleet is not the only aging portion of America’s "nuclear triad."
The 400 Minuteman-III intercontinental ballistic
missiles (ICBMs) currently deployed across three Air Force bases in the
Midwest were first deployed in 1970 with a planned 10-year service
life. They are now expected to last until 2030.
The Navy has 14 Ohio-class ballistic missile submarines
capable of carrying 24 Trident D-5 intercontinental ballistic missiles,
but are roughly 30 years old.
The new posture review calls for each of these
submarines to carry a small number of “low-yield” nuclear warheads,
modified from more powerful ones currently inside the Trident missile.
The new missiles could be deployed in the next few years, officials say.
The Pentagon is worried Russia thinks it can use its smaller nukes against NATO in a limited war without a U.S. response.
“Effective U.S. deterrence of Russian nuclear attack …
now requires ensuring that the Russian leadership does not miscalculate
regarding the consequences of limited nuclear first use,” the review
states.
The last nuclear posture review came out just months
after President Obama set as a policy goal a world without nuclear
weapons in a 2009 speech in Prague.
“Nuclear weapons are the most dangerous legacies of the
Cold War," Obama said in the Czech Republic capital. "The U.S. will
take concrete steps ... [to] begin the work of reducing our arsenals and
stockpiles."
Obama got rid of nuclear-tipped, sea-launched cruise missiles in 2011.
The Pentagon now wants to bring some of those weapons back.
“Every U.S. administration over the past six decades
has called for a flexible and limited U.S. nuclear response options,”
said the review. “Potential adversaries do not stand still. On the
contrary, they seek to identify and exploit weaknesses in U.S.
capabilities and strategy.” The U.S. nuclear arsenal cannot remain
“fixed.”
Mattis spoke to reporters Friday morning, hours before the release of the Nuclear Posture Review.
"What we're trying to do is ensure that our diplomats
and our negotiators are in a position to be listened to when we say we
want to go forward on nonproliferation and arms control. At the same
time, you do so by having an effective, safe deterrent,” said Mattis.
While not mentioning cyberattack directly, the Pentagon
makes clear in this document that the U.S. reserves the right to use
nuclear weapons to respond to any attack on infrastructure or population
centers, even if that attack uses a conventional weapon.
It also addresses the nuclear threat from China, Iran and North Korea, in addition to Russia.
Any nuclear attack by Kim Jong Un would “result in the end of that regime,” the report says.
Greg Weaver, deputy director of strategic capabilities
on the Pentagon’s Joint Staff said “there’s evidence the Russians think
that their coercive nuclear use strategy has some prospect of success.
We want to make sure that we disabuse them of that idea.”
The two new “low-yield” nuclear weapons are designed to do just that, Weaver said.
A sea-launched nuclear cruise missile could be fired
from a warship or a submarine, but is still seven to 10 years from being
fielded, said Dr. Robert Soofer, deputy assistant secretary of defense
for nuclear policy, in a briefing with reporters ahead of the review’s
release.
If Russia returns to compliance with its arms control
obligation and reduces its tactical nukes, the U.S. “may reconsider the
pursuit” of the sea-launched cruise missile, according to the report.
The Pentagon is hoping history will repeat itself.
After the U.S. deployed intermediate-range missiles to Europe, the
Soviet Union signed the 1987 INF treaty with the United States.
President Reagan’s secretary of state, George P. Shultz, said if not for
the deployment of the American missiles, “there would be no incentive
for the Soviets to negotiate seriously for nuclear weapons
reductions.”
Asked how the Russians were likely to respond to the
Pentagon calling for “low-yield” nukes, Soofer replied, “I am sure they
won’t respond well.”
