The Consolidated B-32 Dominator four-engined heavy bomber was ordered at the same time as the Boeing B-29 Superfortress. However, the B-32 was definitely the USAAF's second choice, and was intended primarily as insurance in case the favored Boeing design failed. Since the B-29 ultimately turned out to be an outstanding success, the B-32 was built only in relatively small numbers and used in only a very few combat actions during the last few weeks of the war. Although its brief combat career was unspectacular, it did have the distinction of flying the last aerial combat mission against Japan.
