The Navy gave Alliant Techsystems [ATK] $16.4 million of orders for the AAR-47 A(V)2 warning system that protects aircraft against incoming enemy surface-to-air missiles.

The system protects both helicopters and fixed-wing aircraft.

Some surface-to-air missiles, in the hands of terrorists, are becoming increasing threats, such as the man-portable shoulder-mounted, or MANPADS, air defense weapons that have been used to take down military and civilian aircraft.

ATK also noted that it is developing a new generation of the missile warning system, the AAR-47 B(V)2.

It is in final testing and will provide aircrews with enhanced threat detection in urban and industrial areas by providing them with background clutter level indications. Existing installed AAR-47 systems will be upgradeable to the B(V)2 variant without any change to the aircraft’s A-kit.
