US Mini-nukes and an analysis of a second Korean war

The Department of Energy is producing a new variant of the B61 gravity bomb that will be highly accurate and have a variable yield of 0.3 to 50 kilotons.

The existing (but to be retired) ALCM is believed to have a selectable yield of 5 KTs or 150 KTs. The lower yield is presumably for the boosted primary alone, and the larger yield for the two-stage weapon. The life-extension program for the W80 warhead, which will be carried by the LRSO missile, is expected to provide closer to a “dial-a-yield” option that would allow a number of yield options.

There is a debate that making the mini-nuclear weapons more capable and flexible would encourage their use in say a conflict with North Korea.

The US can destroy North Korea’s air defenses using conventional weapons in about a week just as the US destroyed Air Defenses of Iraq. The question of whether missiles have more stealth or whether there is selectable nuclear yield on 1000 or 2000 nuclear weapons in the US arsenal is not significant. This is because the US can wage more limited nuclear war with lower yield nuclear weapons already.

A 2012 military analysis of North Korea’s attack Seoul would be less damaging than more simplistic analysis.

Despite the thousands of artillery pieces, only 700 heavier guns and rocket launchers, plus the newer 300-millimeter MRLs, have the range to strike Seoul. Seoul has extensive air raid shelters for civilians that will quickly reduce the exposed population density. The North will struggle to keep these heavy artillery units supplied with shells, particularly with its aging supply system. Finally, U.S. and ROK forces will quickly begin hunting down units participating in the bombardment, causing their numbers to drop almost immediately.
