Operational history
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 [Vous devez être inscrit et connecté pour voir ce lien] 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 progression of weapons technology had led to a great reduction in the weight and size of atomic and thermonuclear 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-45's had great value again as a nuclear deterrent.

The program Backbreaker entailed difficult modifications to the aircraft due to many distinct atomic bomb types which were in inventory at the time along with large amounts of electronics which had to be fitted for the nuclear mission.
In addition, the 40 B-45s allocated to the Backbreaker 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 along side the 91st Strategic Reconnaissance Squadron, supplementing the WWII era piston engine R[Vous devez être inscrit et connecté pour voir ce lien] 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 day light missions until early 1952, when they were converted to night operations after an RB-45 was almost lost to a [Vous devez être inscrit et connecté pour voir ce lien]

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.

By 1959 the RB-45C had been replaced by the RB-47E.
The only other nation to use the RB-45C was Britain, which were operated by an ad hoc unit of crews largely drawn from Nos. [Vous devez être inscrit et connecté pour voir ce lien] and [Vous devez être inscrit et connecté pour voir ce lien] squadrons.

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 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 [Vous devez être inscrit et connecté pour voir ce lien] in 1949.
It proved excessively difficult to maintain and was relegated as a ground trainer.
