Raytheon has a long heritage as the original developer and manufacturer of the KI-1C crypto computer family used worldwide for MK XII Identification, Friend or Foe (IFF). Raytheon has remained a leader in IFF crypto by introducing new technologies that have significantly reduced size, weight and power dissipation while improving reliability. Our appliqué solutions offer all of these benefits while maintaining the crypto in a separate 3.5 in. x 4.25 in. x 1 in., 16-oz LRU allowing it to be removed and stored as security procedures dictate without disturbing the integrity of the host interrogator or transponder.
