The US Department of Defense (DoD) is to issue Northrop Grumman with a sole-source contract to supply Australia with two more MQ-4C Triton high-altitude, long-endurance (HALE) unmanned aerial vehicles (UAVs).
A notification posted on the US government’s beta.sam.gov website on 14 April noted that Australia is to add to the one Triton UAV for which a contract has already been placed by exercising its options for two more as part of a wider US Navy (USN) procurement plan. The Royal Australian Air Force (RAAF) plans to field a total of six such vehicles.
