Consolidated B-32 Dominator

The Consolidated B-32 Dominator (Consolidated Model 34) was an American heavy strategic bomber built for the United States Army Air Forces during World War II. A B-32 was involved in the last air combat engagement of the war, resulting in the war's last American air combat death. It was developed by Consolidated Aircraft in parallel with the Boeing B-29 Superfortress as a fallback design should the B-29 prove unsuccessful.
