In 2019, tests by the United States Air Force Research Laboratory (AFRL) demonstrated a 610 Mbit/s data link through Starlink to a Beechcraft C-12 Huron aircraft in flight.[260] Additionally, in late 2019, the United States Air Force successfully tested a connection with Starlink on an AC-130 Gunship.[261]
In 2020, United States Air Force utilized Starlink in support of its Advanced Battlefield management system during a live-fire exercise. They demonstrated Starlink connected to a "variety of air and terrestrial assets" including the Boeing KC-135 Stratotanker.[262]

That’s just the military buying time on a commercial comsat system. The US did that prior to Starlink too, and nobody would mistake an AT&T comsat for a military killsat or reconsat.
