Blackhawk 68 p00

The Lockheed XF-90 made its maiden flight on June 6, 1949. For its planned role of long-range bomber escort, the XF-90 was designed to carry 1,665 gallons internally and in jettisonable wingtip tanks. It had ports for six 20mm cannons under the air intakes, but they were never fitted. The start of the Korean War forced the Air Force to concentrate on planes already in production and the XF-90 was not ordered.
