The North American B-45 Tornado was a multi engine, light-weight bomber aircraft, developed by North American Aviation for the US Air Force.

DescriptionEdit

The first operational jet bomber to be flown by the USAF, it was also the first bomber able to perform aerial-refueling. During the early 1950s, the B-45 was an important part of the American nuclear deterrence. The B-45 was replaced by the B-47 Stratojet.

History Edit

The B-45 evolved from studies began at the end of World War II, in the autumn of 1944[1]; at the time the Americans noticed development of German jet bombers, such as the Arado Ar 234 and the Junkers Ju 287. w

This aircraft was withdrawn from operational use at RAF Sculthorpe on June 11th, 1958 and transferred to Torrejon AB, Spain for fire practice use

The contract was won by North American Aviation, with the NA-130 design, on 8th December 1944.

Most of the military projects were cancelled when World War II ended, but in 1946, the Cold War against the Soviet Union started, so that the US Army Air Force decided to speed up jet bomber development. In the middle of 1946, the XB-45 and the Convair XB-46 were nearly completed, but the Boeing XB-47 and the Martin XB-48 still needed some time to finish. The US Air Force decided to chose the XB-45 over the XB-46, with production starting on 2nd January 1947. The first of the three prototypes, which had been ordered in 1945 as the XB-45 Tornado, made it's initial flight from Muroc Dry Lake on 17th March 1947, with test pilot George Krebs at the controls.[1] Unfortunately, one aircraft crashed and the two pilots died.

Because of expensive maintenance and budget cuts, only 139 aircraft were built out of the 190 planned. The last B-45 was delivered to Wright-Patterson Air Force Base.
