L3Harris will service the self-protection system aboard B-52H and C-130 aircraft.
L3Harris Technologies will provide repair services to the USAF for the AN/ALQ-172 radar warning receiver under a new $39.73 million sole-source contract.
The work is expected to be completed by 12 August 2026, the DoD noted in a 16 August announcement.
Shephard Defence Insight notes that the AN/ALQ-172 equips USAF B-52H Stratofortress strategic bombers and C-130 Hercules large transport aircraft.
The system is optimised to counter radar-guided air-to-air and surface-to-air missiles, and ground-based fire control radars.
Development of the AN/ALQ-172 commenced in 1979 as a result of an initiative to extensively overhaul the AN/ALQ-117 electronic countermeasures system.

Could the next UAS market boom take place beyond the battlefield?
While the headlines remain dominated by the use of drones for combat operations in Ukraine and other conflicts, there are emerging use cases where the technology could usefully feed back into areas and missions outside the war zone.
