US tests new nuclear weapon launched from B-2

Fox News:

The Air Force’s B-2 Stealth bomber has test-dropped an upgraded, multi-function B61-12 nuclear bomb which improves accuracy, integrates various attack options into a single bomb and changes the strategic landscape with regard to nuclear weapons mission possibilities.

Earlier this summer, the Air Force dropped a B61-12 nuclear weapon from a B-2 at Nellis AFB, marking a new developmental flight test phase for the upgraded bomb, Air Force spokeswoman Capt. Hope Cronin told Warrior Maven.

“The updated weapon will include improved safety, security and reliability,” Cronin said.

The B61-12 adds substantial new levels of precision targeting and consolidates several different kinds of attack options into a single weapon. Instead of needing separate variants of the weapon for different functions, the B61-12 by itself allows for earth-penetrating attacks, low-yield strikes, high-yield attacks, above surface detonation and bunker-buster options.

The latest version of the B61 thermonuclear gravity bomb, which has origins as far back as the 1960s, is engineered as a low-to-medium yield strategic and tactical nuclear weapon, according to nuclearweaponsarchive.org, which also states the weapon has a “two-stage” radiation implosion design.

“The main advantage of the B61-12 is that it packs all the gravity bomb capabilities against all the targeting scenarios into one bomb. That spans from very low-yield tactical “clean” use with low fallout to more dirty attacks against underground targets,” Hans Kristensen, Director of the Nuclear Information Project, Federation of American Scientists, told Warrior Maven.

It is a weapon system that should also be a warning to places like North Korea and Iran who wish to challenge the US with nuclear weapons.
