U.S. Air Force Research Laboratory (AFRL)

General Atomics Aeronautical Systems announced Feb. 29 that its XA-67A Off-Board Sensing Station (OBSS) flew for the first time the day before.

The service will select two companies to begin building CCAs, though with a cost-sharing agreement to bring along a third.

The U.S. AFRL has decided to wind down its ambitious air-breathing hypersonic Mayhem development program, citing insufficient operational demand.

The San Diego-based UAS, propulsion and sensor company decided not to offer a bid for a high-profile UAS program as a prime contractor.

The service, blocked from starting new acquisition programs, used a long-standing autonomy demonstration effort to begin CCA work.
