DSEI 2017: Mid-2020 is hard backstop date for adopting Mode 5 IFF

14 September 2017

Allied armed forces around the world are scrambling to adopt Mode 5 identification friend or foe (IFF) systems, Hensoldt said at the Defence and Security Equipment International (DSEI) 2017 defence exhibition.

This is because the US National Security Agency will stop generating keys for unsecure Mode 4 IFF, said Thorsten Oelgart, head of air traffic control radar, IFF, and datalink sensor sales at Hensoldt Sensors. He reported that 57 countries were eligible, with 12 having made significant progress, while others were still implementing Mode 4.

Preparations for Mode 5 IFF have been under way since 1995 and EADS, before it became Cassidian and more recently Hensoldt, delivered the first transponder to the German Navy for its K130 corvette in 2006.
