Pentagon Deploys New Sub-Launched, Low-Yield Nuclear-Armed Missile

(Washington, D.C.) Senior Pentagon officials have announced that a new, nuclear-armed, submarine-launched, low-yield ballistic missile warhead is now operational, bringing a new measure of potential precision nuclear attack strikes to DoD’s current deterrence posture. 

The weapon, called the W76-2 low-yield submarine launched ballistic missile, “demonstrates to potential adversaries that there is no advantage to limited nuclear employment, because the United States can credibly and decisively respond to any threat scenario,” Mr. John Rood, Under Secretary of Defense for Policy, announced in a Feb. 4 Pentagon statement.

The now operational weapon, Pentagon officials tell Warrior, is now “fielded.” The new weapon does seem to have emerged quickly, as initial draft plans were underway just within the last year or two. Significantly, Rood’s statement specifically cites that Russia may “believe that employment of low-yield nuclear weapons will give them an advantage over the United States and its allies and partners.”  He adds that U.S. counterattack options ensure a “prompt” response.

One tactical advantage to a weapon of this kind, naturally intended to prevent nuclear war, is that it ensures a catastrophic, yet targeted nuclear response option in the event the U.S. is attacked with nuclear weapons. 

Pentagon officials tell Warrior the low-yield missile warhead, or re-entry body, involves a modification of the existing Trident II D5 submarine-launched, nuclear-armed ballistic missile. 

“The low-yield warhead is engineered for a submarine-launched ballistic missile,” the official said. 

The modification effort is intended to align with the with DoD’s Nuclear Posture Review (NPR) released several years ago by the Trump administration and Pentagon, which calls for the introduction of several new lower-yield nuclear weapons.

The 2018 Nuclear Posture Review identifies a requirement to “modify a small number of submarine-launched ballistic missile warheads.”

The new SLBM brings a third warhead option to nuclear attack. As it currently stands, the Trident can carry the W76-1 or W88, Pentagon officials have told Warrior. 

Low-yield is as it sounds - smaller, more surgical and less destructive than most nuclear weapons. While some experts say a low-yield weapon could be in the range of 20 kilotons, senior Pentagon officials tell Warrior “there is no formal definition of what is low yield and what is not. It is a term of art used in arms control but we have not set a limit.”

This low-yield nuclear missile option does appear to add something not currently present in the US arsenal. While the emerging B-21 will be configured to fire lower-yield, more precise B61 Mod 12 weapons, a sub launched nuclear weapon brings newer avenues of attack and long-range strike without having to operate air assets over or near heavily defended areas. The F-35 is also being engineered to carry nuclear weapons. 

Yet another proposed nuclear weapons application, according to those identified by the NPR, is a shorter-range sea-launched cruise missile. Nuclear cruise missile options, potentially fired from a submarine or ship, can bring even more precision, Han Kristensen, Nuclear Information Project at the Federation of American Scientists, told Warrior in an interview last year. 

A sea launched cruise missile could include a handful of possibilities. The Pentagon previously had a nuclear armed Tomahawk missile, which was retired in 2011.

Warrior is very interested in your thoughts regarding whether deploying this weapon could escalate tensions - and possibly lower the threshold to some kind of nuclear weapons engagement? Or will something like this rather further deter Russia and have the intended impact? Let us know here at Warrior and thanks for reading. Karl - Warrior moderator.

USA MUST let its enemies know that Americans will respond with appropriate destruction so the enemies they will pay a serious cost of destruction.
