In 1946, rising tensions with the caused the (USAAF) to assign higher priorities to jet bomber development and production. By mid-1946, the XB-45 and neared completion, but the Boeing and were still two years away. The USAAF chose to evaluate the first two designs to determine which would be superior operationally. The B-45 proved a superior design, and on January 2, 1947, a contract for immediate production of B-45As was signed. It had been planned to equip five light bomb groups and three light groups with B-45As, but as the B-47's development and flight-testing made future production all but certain, the future of the B-45 became increasingly uncertain, and in mid-1948 the U.S.

Began to question its value. Soon afterwards, budget restraints reduced Air Force expenditure and B-45 production was reduced to a total of 142 airframes. Further budget cuts in 1950 forced the Aircraft and Weapons Board to cancel 51 of the 190 aircraft on order. The cancellation of the 51 was announced 7 January 1949.

The B-45 was later replaced by the supersonic. Operational history [ ] Korean War [ ] Continuously plagued by engine problems along with numerous other minor flaws, the B-45 regained importance when after the United States entered the in 1950, it proved its value both as a bomber and as a reconnaissance aircraft. The mass dedication of U.S. Forces to the Korean War revealed the vulnerability of forces in Europe to Soviet attack, and it was in this light that the Air Force made an important decision about the future of the B-45.

Icao document 8168. The B-45, like most post- American bombers, could carry both nuclear and conventional bombs. The progress of weapons technology had led to a great reduction in the weight and size of nuclear weapons in the U.S. Inventory, effectively allowing smaller aircraft such as the B-45 to carry out nuclear strikes, a mission which had initially been confined to heavy bombers. Suddenly, the small fleet of B-45s had great value again as a nuclear deterrent., sometimes called Operation Backbreaker, entailed modifications to the aircraft for nuclear missions.
