Misty 2 (USA-144) (NROL-9)

These satellites are suspected to be stealthy electro-optical reconnaissance satellites. The program name for developing an stealth IMINT capability is reportedly "Misty". The Misty satellites are likely derived from the KH-11 Block 3 satellites with low observable features added. The relation to the 8X or EIS program is unclear, but there might be common elements.
