Collins Aerospace has more than 70 years of experience in IFF technology. Our IFF transponders and interrogators, including advanced Mark XII A and AIMS-certified solutions, are deployed on more than 150 platforms worldwide, across military applications in the air, on land or at sea.

In today’s dynamic global environment, it’s critical to use a proven, secure question-and-answer system that distinguishes platforms as friendly, enemy or neutral.

Identification Friend or Foe has relied on Mode 4 since the 1960s. However, as of June 2020, the U.S. Department of War AIMS program office ceased generation of Mode 4 Crypto keys and  mandated the conversion for all systems to Mode 5.

Mode 5 significantly improves the ability to identify and track friendly aircraft, enhanced situational awareness for command and control and Combat-ID functions. Mode 5 improvements include new cryptography, stronger security features, modern signal modulation techniques and greater data content. The increased data capacity enables encrypted transmission and supports new data formats, including National Origin codes and Platform Identification Numbers.

Mode 5 also includes lethal interrogations designed to prevent fratricide. This feature provides  a final challenge to a targeted platform before weapons engagement. Even platforms operating under radio silence or “EMCON” (emission control) can respond to Mode 5 interrogations.

To ensure these IFF systems are properly integrated, Collins works directly with customers, including providing analysis, planning, platform design and development, integration, and test support.
