The B-45 achieved many "firsts." It was the first American four-engine jet bomber to fly; the first American production jet bomber; the first jet bomber capable of carrying an atomic bomb; and the first multi-jet reconnaissance aircraft to refuel in mid-air.
Design of the Tornado began during World War II, and the B-45 made its first flight in March 1947. North American built 142 B-45s, including 10 long-range B-45Cs with wingtip fuel tanks and 33 RB-45Cs configured for high-altitude photo reconnaissance and aerial refueling.
Based at RAF Sculthorpe, England, from 1952-1958, B-45s of the 47th Bomb Wing (Light) were a key nuclear deterrent against a Soviet ground attack in Europe. Also flying from RAF Sculthorpe were USAF RB-45Cs from the USAF 19th Tactical Reconnaissance Squadron and Royal Air Force (RAF) Special Duty Flight crews. These RAF RB-45 crews flew highly classified reconnaissance missions deep into communist territory.
The aircraft on display was returned to the USAF by Pratt & Whitney Aircraft Division, where it had been on loan for engine testing. Flown to the museum in 1971, it is painted in the markings of the 47th Bomb Wing (Light).
