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 its 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 pilots 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.)
