USAF to upgrade A-10Cs with 3D-audio for pilot situational awareness

The US Air Force (USAF) is moving ahead with plans to equip its Fairchild-Republic A-10C Thunderbolt II combat aircraft with 3D-audio to enhance the situational awareness of its pilots.

Following a request for information (RFI) issued in December 2017, a notification was issued by the service on 5 November disclosing that it is to award Terma a sole-source Indefinite Delivery/Indefinite Quantity (IDIQ) contract to equip between 150 and 200 of its A-10Cs with a system to provide the pilot with 3D-audio cues.
As noted by the USAF, the overall acquisition strategy of the 3-Dimensional Audio Program is to deliver a commercial off-the-shelf (COTS) system to drastically improve the spatial, battlespace, and situational awareness of its A-10C pilots by providing audio cues that are accurate to within 15° of both azimuth and elevation.
