Well

that's great news.

Deployment of new US nuclear warhead on submarine a dangerous step, critics say

"First submarine to go on patrol armed with the W76-2 warhead makes a nuclear launch more likely, arm control advocates warn"

Yep.

"The Trump administration’s nuclear posture review (NPR) in February 2018, portrays this warhead as a counter to a perceived Russian threat to use its own “tactical” nuclear weapons to win a quick victory on the battlefield.

Advocates of W76-2 argued that the US had no effective deterrent against Russian tactical weapons because Moscow assumed Washington would not risk using the overwhelming power of its intercontinental ballistic missiles in response, for fear of escalating from a regional conflict to a civilian-destroying war.

Critics of the warhead say it accelerates a drift towards thinking of nuclear weapons as a means to fight and win wars, rather than as purely a deterrent of last resort. And the fielding of a tactical nuclear weapon, they warn, gives US political and military leaders a dangerous new option in confronting adversaries other than Russia."
