KH-11


American military surveillance satellite. 9 launches, 1976.12.19 (KH-11 no. 1) to 1988.11.06 (USA 33). Also known as Kennan, Program 1010. Used systems developed for KH-10 Manned Orbiting Laboratory.

First electro-optical digital transmission imaging reconnaissance satellite. Ground resolution 0.15 m with a 2.3 m diameter mirror. Believed to be similar to Hubble Space Telescope (they used same shipping container and specially-modified aircraft). Data transmitted via SDS military relay satellites.

AKA: Kennan; 5500; Crystal.
Gross mass: 13,500 kg (29,700 lb).
Height: 19.50 m (63.90 ft).
First Launch: 1976.12.19.
Last Launch: 1988.11.06.
Number: 9 .

The designs finally put into production were derived from the Titan II ICBM. Titan outlived the competing NASA Saturn I launch vehicle and the Space Shuttle for military launches. It was finally replaced by the USAF's EELV boosters, the Atlas V and Delta IV. Although conceived as a low-cost, quick-reaction system, Titan was not successful as a commercial launch vehicle. Air Force requirements growth over the years drove its costs up - the Ariane using similar technology provided lower-cost access to space. More...
