The U.S. Air Force tested a B-61 on the Nevada Test and Training Range.
Between Jun. 29 and Jul. 1, the Air Force Nuclear Weapons center tested a (dummy) B61 nuke weapon on the Nevada Test and Training Range to the northwest of Las Vegas.
It was the first development flight test of the B61-12, the latest update to the nuclear gravity bomb that has been used since the 1960s.
According to the U.S. Air Force, “the B61 is in the process of a life-extension program, which includes upgrading aging components and a new tail kit assembly. When the program is completed, the B61-12 will replace four different B61 variants in the inventory.”
The video below shows preparation and drop of the bomb from an F-15E Strike Eagle out of Nellis Air Force Base. Pretty interesting to see is the release of the nuke, with the spin rockets activating shortly after separation for free fall weapon stabilization.
