Northrop Grumman has received a prototype and risk-reduction contract from the USN to integrate sense-and-avoid (SAA) capabilities with the MQ-4C Triton high-altitude long-endurance UAV. The value of the deal was undisclosed. SAA would allow Triton to operate in controlled airspace used by crewed aircraft. It is a focus of the next developmental increment of the MQ-4C system and a ‘critical element of the cooperative development programme requirements defined between the USN and Royal Australian Air Force’, Northrop Grumman announced on 10 May.
