On behalf of the Bulgarian government, the NATO Communication and Information Agency (NCI Agency) has signed a contract with Hensoldt for the delivery of MSSR 2000 ID secondary radars as well as cryptographic and test equipment. The multi-million euro contract also includes related services.

Hensoldt writes that IFF systems, so-called secondary surveillance radars (SSR), precisely identify aircraft by automatically sending interrogation signals that are answered by so-called transponders on board of friendly aircraft. This allows field commanders to quickly distinguish between friendly and hostile forces with the help of IFF. In contrast to the previously used "Mode 4", "Mode 5" uses complex encryption techniques to avoid hostile signal manipulation so that the identification process is absolutely reliable and secure.

With the MSSR-2000-ID secondary radars, mode 5 is being implemented in Bulgaria, which is currently being introduced in all western armies as a prerequisite for joint operations by US / NATO and allied armed forces.

According to Hensoldt, he has received orders to upgrade the IFF systems of the German, French and British armed forces to the "Mode 5" standard and has already supplied IFF systems - including cryptographic devices - for ground and naval applications to several NATO countries. In total, Hensoldt has more than 400 IFF systems under contract in 42 countries.
