The first XB-70 carried out its maiden flight in September 1964 and many more test flights followed. [71] The data from the XB-70 test flights and aerospace materials development were used in the later B-1 bomber program, the American supersonic transport (SST) program, and via espionage, the Soviet Union's Tupolev Tu-144 SST program.

North American Aviation (NAA) was a major American aerospace manufacturer that designed and built several notable aircraft and spacecraft. Its products included the T-6 Texan trainer, the P-51 Mustang fighter, the B-25 Mitchell bomber, the F-86 Sabre jet fighter, the X-15 rocket plane, the XB-70 bomber, the B-1 Lancer, the Apollo command and service module, the second stage of the Saturn V ...
The General Electric YJ93 turbojet engine was designed as the powerplant for both the North American XB-70 Valkyrie bomber and the North American XF-108 Rapier interceptor. The YJ93 was a single-shaft axial-flow turbojet with a variable-stator compressor and a fully variable convergent/divergent exhaust nozzle.
The first XB-70 — nicknamed Valkyrie following a naming contest — was rolled out in Palmdale, California, on May 11, 1964. With a wingspan of over 100 feet, six General Electric turbojet ...

The aircraft was powered by two General Electric J93 turbojet engines, also used in North American's XB-70 Valkyrie bomber, in the fuselage. [17] The F-108 was intended to carry the Hughes AN/ASG-18 radar, the U.S.'s first pulse-Doppler radar set. [18] It was to have look-down/shoot-down capability, but could track only one target at a time.
The XB-70 Valkyrie was chosen in 1957 to replace the Hustler but suffered as a result of a switch in doctrine from a high- to a low-altitude flying profile. By the late 1950s, however, anti-aircraft surface-to-air missiles (SAMs) could threaten high-altitude aircraft, [12] as demonstrated by the 1960 downing of Gary Powers' U-2. [13]
