GERMANY. As part of the modernization of all NATO identification-friend-or-foe (IFF) systems to the secure new "Mode 5" standard, sensor solution provider HENSOLDT is equipping air surveillance radars of the German Air Force with the latest generation of IFF systems.

As part of an order from the Federal Office of Bundeswehr Equipment, Information Technology, and In-Service Support, BAAINBw, HENSOLDT claims the company is supplying secondary radar systems and individual components.

Based on automated electronic signals, IFF systems are designed to ensure that friendly units are detected or identified at an early stage by responding to interrogation signals with the correct signal. Adversarial units that do not respond can then be mitigated. 

According to officials, all NATO countries are currently converting their IFF systems to the latest Mode 5 standard, which uses advanced cryptographic techniques to secure against electronic jamming by adversaries.
