The full text of the letter is below:
May 4, 2018
The Honorable Mitch McConnell
United States Senate
Washington, DC 20510
Dear Senator McConnell,
We ask you to reject the proposal in the 2018 Nuclear Posture Review for a new “lowyield” warhead for the Trident II D5 submarine-launched ballistic missile. This new weapon is unnecessary and would increase the risk of miscalculation and wider nuclear use. The Administration’s FY2019 budget included $22.6 million in DoD funding and recently added $65 million in DOE funding for this weapon.
There are three reasons you should oppose this new weapon.
First, the Trump administration’s case for this new low-yield warhead rests on the faulty premise that there is a “deterrence gap” with Russia. Because of this supposed “gap,” the Nuclear Posture Review suggests that Russia might use a low-yield nuclear weapon first in a conflict and assume the United States would be “self-deterred” from responding because the Pentagon lacks sufficient low-yield nuclear options.
But there is no gap. The United States already deploys several types of B61 bombs and an air-launched cruise missile with low-yield options, totaling approximately 1,000 weapons in its arsenal. In addition, current plans call on the United States to invest more than $150 billion to field a new B61 bomb with low-yield options, a new cruise missile and warhead with low-yield options, as well as a new stealth bomber and fighter aircraft to deliver these weapons.
Second, in the highly unlikely event of a Russian limited nuclear attack, there is no evidence to suggest that a limited US nuclear counterstrike would end the conflict. In fact, such a response would increase the risk of further nuclear escalation.
As President Reagan’s Secretary of State George Shultz testified to Congress on January 25, 2018, “The idea of a low-yield nuclear weapon is kind of a mirage. It is a nuclear weapon… [It] invites escalation.”
Third, a low-yield warhead on a ballistic missile invites miscalculation. If Russia detected an incoming Trident missile, it would not know whether it was armed with a low-yield or high-yield warhead. Based on a worst-case scenario, it may feel pressured to respond quickly by launching a missile of its own, further increasing the risk of unintended nuclear escalation.
It was this same discrimination problem that led Congress to soundly reject the idea of deploying conventionally-armed Trident missiles in 2008. Congress was rightly concerned about the inability of nuclear-armed adversaries to determine whether a ballistic missile launched from a US submarine was armed with a conventional or nuclear warhead. If Russia detected an incoming missile, it would have to assume it could be nuclear-armed, which could lead it to launch a nuclear weapon in response.
When testifying before Congress on March 20, 2018, General Hyten, the commander of US Strategic Command, said, “I have everything I need today to deter Russia from doing anything against the United States of America. We’re fully ready against any threat that exists today, without a doubt.”
Based on that assessment, it is unclear why the Administration is seeking to fast-track the development of a low-yield warhead in FY2019.
We urge you to deny funding for the “low-yield” Trident warhead.
