For the U.S. Air Force’s CCA Increment 1, the General Atomics YFQ-42A Dark Merlin is competing against the Anduril Industries YFQ-44A Fury, and the service this year is to pick a winner and begin Increment 2.

“The MQ-28 Ghost Bat is designed to complement existing crewed aircraft by performing a variety of roles, including surveillance, electronic warfare, and force multiplication, all while maintaining a low radar profile,” Boeing said on June 1. “This [low RCS] milestone further demonstrates the platform’s maturity, survivability, and ability to deliver cost-effective advanced capability for modern air combat operations.”

Boeing said that the MQ-28 has fired an Advanced Medium-Range Air-to-Air Missile against a target drone, teamed with other Ghost Bats and with an E-7A Wedgetail airborne early warning aircraft and an F/A-18F Super Hornet, and has conducted three “international” test flights over the Pacific Ocean while using U.S. Naval Base Ventura County in Point Mugu, Calif.
