Raytheon has delivered the 500th ALR-67(V)3 digital radar warning receiver to the US Navy.

The ALR-67(V)3 is the US Navy standard for digital radar warning receiver technology and is an integral part of modernisation programmes for the US and international customers.

The radar is installed on all frontline, carrier-based F/A-18E/F Super Hornet tactical aircraft to provide enhanced aircrew survivability through improved situational awareness.

The channelised receiver architecture allows successful detection of emitters in high pulse density, and of weak distant signals despite interference from strong nearby transmitters.
