The MQ-28A Ghost Bat made its first operational exercise debut at Valiant Shield 2026, flying alongside the USAF F-15EX Eagle II and conducting FARP refueling with an HC-130J. This marks the first integration of a collaborative combat aircraft into a multinational joint force exercise, validating human-machine teaming concepts for future airpower. Boeing deployed a Block 1 test asset from the Northern Mariana Islands, where the MQ-28 operated for 10 days executing offensive and defensive counter-air missions. The USAF Experimental Operations Unit used this debut to develop tactics, techniques, and procedures for integrating autonomous CCAs with tactical fighter squadrons. The event also featured the first FARP training between a CCA and an HC-130J, testing agile combat employment away from major bases.
