The Lockheed XF-90 was designed to meet a U.S. Air Force requirement for a long-range bomber escort. Two prototype aircraft were built under a contract from the Air Force. The XF-90 made its maiden flight on June 6, 1949. The XF-90 was a large and heavy aircraft and the engines with which it was fitted were inadequate. Because Lockheed's design proved underpowered, McDonnell's XF-88 won the production contract in September 1950.
The Blackhawks had the XF-90's notoriously weak engines replaced with a single, much more powerful engine of their own design, thus turning the aircraft into the fastest and longest ranged ship of its time. Some sources refer to this single engine version as the F-90B model of the aircraft .
