1. Short title This Act may be cited as the Hold the Low-Yield Nuclear Explosive Act or the Hold the LYNE Act . 2. Findings Congress finds the following: (1) The United States has an unparalleled nuclear arsenal, including 1,350 strategic nuclear warheads deployed on intercontinental ballistic missiles, submarine-launched ballistic missiles, and strategic bombers. (2) A new low-yield nuclear weapon to be carried on a ballistic missile submarine risks lowering the threshold for nuclear use and increasing the chance of miscalculation that could escalate into all-out nuclear exchange. (3) When launched, such a low-yield nuclear warhead would be indistinguishable to an adversary from the high-yield W76 and W88 submarine-launched warheads. (4) On January 25, 2018, former Secretary of State George Schultz testified before the Committee on Armed Services of the Senate that A nuclear weapon is a nuclear weapon. You use a small one, [and] then you go to a bigger one. I think nuclear weapons are nuclear weapons and we need to draw the line there. . (5) Former Senator Sam Nunn and former Secretary of Energy Ernest Moniz stated in an op-ed on February 1, 2018, that, The most immediate priority should be to structure and posture U.S. and Russian nuclear forces to deter nuclear use and reduce the risk of an accidental, mistaken or unauthorized launch. Against this backdrop, the current Russian concept of escalate to de-escalate —i.e., limited nuclear use designed to create a pause in the conflict and open a pathway for a negotiated settlement on Moscow’s terms—and U.S. calls for more usable nuclear weapons taken together make the world a vastly more dangerous place. . (6) The ballistic missile submarines of the United States have never carried low-yield nuclear warheads, and setting a historical precedent could undermine the unique and paramount role of ballistic-missile submarines as the assured, survivable second-strike capability of the United States to deter large-scale nuclear war. (7) The United States should reject
