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.

It was known as the first operational jet bomber that served the United States Air Force, and the first multi-engine jet bomber to be refueled in midair.

On March 17, 1947, the North American B-45 Tornado, a fine but often forgotten plane, made its first flight and was fielded for duty a year later, becoming the first U.S. jet-powered nuclear bomber. Alarmed by the development and deployment of the Arado 234 jet bomber by Nazi Germany, the U.S. scrambled to produce a jet bomber of its own.

2020年2月29日 · Back on December 4 th, 1950, the very first jet-powered bomber was shot down by a jet fighter. This jet bomber was the North American B-45 Tornado which had been shot down by a MiG-15. From the shot down B-45, only one crewmember survived who also was presumed dead after he landed in the Chinese region.

2017年11月7日 · Although it incorporated the latest technology for its engines by using J47 turbojets, the B-45 had a straight (unswept) wing reminiscent of the slower reciprocating engine bombers built during the war years. A dedicated gunner’s position was incorporated beneath the vertical tail with two 12.7mm Browning machine guns for limited self-defense.

While the B-45 was far from ideal, and its limited range meant it would be a one way mission, the B-45 was all we had until the B-47 came on-line. The final production run of B-45 was the C model.
