Northrop Grumman B-2 Spirit B-2A Block 10

The USAF accepted production B-2s in three successive configurations — Blocks 10, 20 and 30 — and the first covered ten aircraft: AV-7 to AV-16, serials 88-0328 to 88-0332, 89-0127 to 89-0129, 90-0040 and 90-0041. The first operational aircraft, Spirit of Missouri (AV-8, 88-0329), was delivered to Whiteman Air Force Base, Missouri, on 17 December 1993; the rest arrived between 1994 and 1996.

Block 10 provided limited combat capability: it could not launch conventional guided weapons and carried only Mk-84 2,000-pound conventional bombs or gravity nuclear weapons. Aircraft in this configuration, all based at Whiteman, were therefore used primarily for crew training. From July 1995 they began returning to the Northrop Grumman modification line at Palmdale to be brought up to Block 30 standard, a process completed in June 2000.

The fleet's hardest events belong to this block: AV-12 Spirit of Kansas (89-0127) crashed on 23 February 2008 at Andersen Air Force Base, Guam; AV-11 Spirit of Washington (88-0332) was severely damaged by fire in February 2010 and repaired; AV-14 Spirit of Georgia (89-0129) suffered wing damage after a landing gear collapse in September 2021; and AV-16 Spirit of Hawaii (90-0041) was retired on 10 December 2022 after a crash landing.
