 budget restraints reduced Air Force expenditure and B-45 production was reduced to total of 142 airframes. Further budget cuts in the FY 1950 forced the Aircraft and Weapons Board to cancel 51 of the 190 aircraft on order.

The Korean War

Continuously plagued by engine problems along with numerous other minor flaws, the B-45 regained importance when the United States entered the Korean War in 1950 and would prove its value both as a bomber and in a reconnaissance role. The mass dedication of U.S. Forces to the Korean War revealed the vulnerability of the North Atlantic Treaty Organization 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. The B-45, like all post World War II U.S. 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 U.S. inventory, effectively allowing smaller aircraft such as the B-45 to carry out nuclear strikes, a mission which had initially been limited to heavy bombers. Suddenly, the small fleet of B-45s had great value again as a nuclear deterrent.

Operation Fandango, sometimes called Operation Backbreaker, entailed modifications to the aircraft for nuclear missions. In addition, the 40 B-45s allocated to the program also were equipped with a new defensive system and extra fuel tanks. Despite the magnitude of the modification project, plus ongoing problems with the early jet engines, atomic-capable B-45s began reaching the United Kingdom in May 1952, and deployment of the 40 aircraft was completed in mid June. It was at about this same time that RB-45s of the 323rd Strategic Reconnaissance Squadron began to arrive in Japan to fly alongside the 91st Strategic Reconnaissance Squadron, supplementing the WWII era piston engine RB-29s which had proved to be easy targets for North Korean MiGs. The RB-45s would provide valuable intelligence throughout the remainder of the Korean War despite the limited number of airframes which were available. RB-45Cs flew many daylight missions until early 1952, when they were converted to night operations after an RB-45 was almost lost to a MiG-15.

Post war

All 33 RB-45Cs built were assigned to the 91st Strategic Reconnaissance Wing's 322nd, 323rd and 324th Strategic Reconnaissance Squadrons. The RB-45C also flew several long-range reconnaissance missions over the Soviet Union

 during the mid 1950s. On July 29, 1952, an RB-45C made the first non-stop Trans-Pacific flight, having been refueled twice by KB-29s along the way. Maj Lou Carrington and his crew of the 91st Reconnaissance Wing flew from Alaska to Japan in 9hrs 50mins, winning the MacKay Trophy for their achievement. Within the 91st SRW, by 1954 the RB-45C had been replaced by the RB-47E. The phased out RB45Cs went to the 19th Tactical Reconnaissance Wing which used them until about 1959.

By the end of the 1950s all B-45s were removed from active duty service. However, a few continued to act as test aircraft into the early 1970s.

The first flight of the XB-45 was on 17 March 1947 from Muroc Army Air Field. A total of 131 test flights were flown by the three prototype aircraft, one being destroyed early on, killing two pilots.

The USAF accepted one of the two survivors on 30 July 1948, the other on 31 August. One was damaged beyond repair in an accident. The last XB-45 was delivered to Wright-Patterson Air Force Base

The first production B-45 flew in February 1948. The Air Force took delivery of 22 in April 1948. They were powered by the less-powerful J35 turbojets, and not considered combat-ready. They were assigned to training duties and to conduct various test programs. The next batch were powered by the superior J47 turbojets. The first B-45As entered service in November 1948 with the 47th Bombardment Group. The initial order of 96 was completed in March 1950.
