KH 12-3



KH 12-3 was launched from Vandenberg AFB aboard a Titan 4 rocket for the US Department of Defense. It was an electro-optical reconnaisance satellite that succeeded the KH-11 series. It was heavier 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 KH-11 satellites. Data were transmitted via the SDS military relay satellites.
