About IFF
With our breadth of expertise in avionics and sensor systems, BAE Systems offers significant capability in the area of IFF systems. Spanning more than 75 years of IFF experience, we have delivered over 13,000 transponders, 1,000 interrogators, and 4,500 combined interrogator/transponder systems. Our advanced IFF products enable warfighters to identify friendly forces and make informed decisions in time-critical situations.
IFF technology can be used on existing, new, and emerging platforms including unmanned aerial vehicles, ships, fixed-wing aircraft, and helicopters.
IFF product family
IFF Transponders
Our transponders allow aircraft and ships to be identified 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. Products: AN/APX-117, AN/APX-118, AN/APX-123, AN/APX-124, AN/DPX-7 Reduced Size Transponder.
- Flexible interface designed to accommodate retrofit and new installations
- Modes 1, 2, 3/A, C, 4, 5, S, and ADS-B
- DoD AIMS certified
