KIT-1A Mk XV IFF Crypto

This was the first device to encode/decode Mk XV IFF. In 1985, the US Department of Defense was pressuring the Joint Combat Identification Program Office, at Wright-Patterson Air Force Base, Ohio, to accelerate the development timetable and cut the projected cost of a new NATO identification system, the Mk 15, intended to replace the long-used Mk 12 Identification Friend or Foe (IFF) system.
