Lockheed U-2A


The U-2 was designed and built for surveillance missions in the thin atmosphere above 55,000 feet. An unusual single-engine aircraft with sailplane-like wings, it was the product of a team headed by Clarence L. "Kelly" Johnson at Lockheed's "Skunk Works" in Burbank, California. The U-2 made its first flight in August 1955 and began operational service in 1956. Its employment was kept secret until May 1, 1960, when a civilian-piloted U-2 was downed on a non-USAF reconnaissance flight over Soviet territory.

USAF U-2s have been used for various missions. On October 14, 1962, Maj. Richard S. Heyser piloted a U-2 over Cuba to obtain the first photos of Soviet offensive missile sites. Maj. Rudolph Anderson, Jr. was killed on a similar mission eight days later when his U-2 was shot down. U-2s also have been used in mapping studies, atmospheric sampling and for collecting crop and land management photographic data for the Department of Energy.

Great unclassified info regarding the U2 Program is available on the FAS.ORG IRP pages.

Sensor packages from the past and present are shown in this slide.

Planned upgrades to the U2 Life Support System include initial issue and spare S-1034 space suit helmets, coveralls, gas retainer liners, and gloves, for U-2 high altitude operations to replace the no longer supportable S-1031 space suit. This upgrade also supports on-board life support and survival kits. Includes an SR-71 type oxygen line to the space suit which will greatly improve pilot comfort and safety. The space suit is necessary for high altitude operations which provide the U-2 both it’s mission capability as well as its primary defense against hostile forces. The special survival kits are necessary for the high altitude environment and compensate for the space suited pilot’s lack of mobility. A survival kit replacement is needed due to age and wear. The original kits were fabricated in 1967/1968 for the U-2R with additional kits fabricated in 1980/1981 for the TR-1. Money was saved over the years by using a four year overhaul interval instead of replacing kits. (The basic components are quickly approaching the end of their serviceable life.)
