KH 11-10



KH 11-10 was deployed from the orbiting STS-36 for the US Department of Defense. It was an electro-optical reconnaisance satellite that was heavier than other KH-11 satellites and believed to include a signals intelligence payload. It had wider spectral band sensitivity, perhaps "real time" television capability, and other improvements compared to the other KH-11 satellites. The satellite was reported to have malfunctioned after being placed in orbit.
