NGIFF interrogator for Italian Navy’s NH90s

27th February 2017 - 09:45 GMT | by The Shephard News Team


Leonardo will provide its New Generation Identification Friend or Foe (NGIFF) interrogator, called the SIT434/5, for the Italian Navy NH90 Nato Frigate Helicopters (NFHs) under an $11 million contract awarded by the NATO agency NAHEMA on behalf of the Italian Ministry of Defence.

The SIT434/5 has been integrated on the NH90 NFH by Leonardo and qualification tests have been completed successfully.

The system gives the fleet Mode 5 IFF capability, allowing crew to identify forces and distinguish them from potential threats. The system does this by transmitting a challenge signal to an unidentified aircraft and verifying the automatic responses received. The SIT434/5 interrogator is the part of the IFF system that sends out the challenge signal.

NATO members are required to have mode 5-compatible equipment, which provides better encryption security and other advantages over older systems, installed by 2020 when the old Mode 4 signal is scheduled to be turned off. The SIT434/5 will allow Italy's NH90 NFHs to continue to operate jointly with NATO allies post-2020.
