Identification Friend or Foe (IFF)

IFF Transponders

IFF Transponder
BAE Systems IFF transponder products are the standard for the U.S. Navy and U.S. Army.

Our transponders identify aircraft and ships as friendly forces by responding to interrogations from ground-based or airborne IFF systems. The transponders installed on aircraft and naval vessels establish the identity of friendly forces.


BAE Systems’ transponder products incorporate all the advanced features required for today’s global military/civil air traffic control environments. They are fully Mode 5 capable and have received AIMS certification.
