The US Army on 26 September selected the Griffon Aerospace Valiant and Textron Systems Aerosonde Mk 4.8 Hybrid Quadrotor (HQ) for the second phase of the Future Tactical Unmanned Aircraft Systems (FTUAS) competition.

Phase 2 of FTUAS is intended to advance the two designs through critical design review (CDR), the last step before building and testing a prototype aircraft.

“Following the CDR, the remaining [companies] will participate in flight demonstrations and MOSA [Modular Open Systems Architecture] third-party verification in the third agreement option period before delivering production representative weapon systems and support equipment for developmental testing and operational demonstrations,” the army said in a statement. “These systems will undergo numerous evaluation activities such as environmental testing, electromagnetic environmental effects testing, transportability testing, MOSA verification, flight-testing, and technical manual verification conducted at [corporate] and government facilities.”
