USSF-7 (OTV-6)

The Boeing X-37, also known as the Orbital Test Vehicle (OTV), is a reusable uncrewed spacecraft. It is boosted into space by a launch vehicle, then re-enters Earth's atmosphere and lands as a spaceplane. The X-37 is operated by the United States Air Force for orbital spaceflight missions intended to demonstrate reusable space technologies. It is a 120%-scaled derivative of the earlier Boeing X-40. The spacecraft successfully landed at the KSC Shuttle Landing Facility on November 12, 2022, at 5:22 AM EST, 10:22 AM UTC. The spacecraft spent 908 days in orbit, its longest flight yet.

FalconSAT-8 launched as a hosted experiment with the X-37B Orbital Test Vehicle (OTV). The satellite remained attached to the OTV’s service module until it was deployed in October 2021. FalconSAT-8 hosts five experiments. The Magnetogradient Electrostatic Plasma thruster (MEP), the Metamaterials Antenna (MMA), the Carbon Nanotube Experiment (CANOE), the Attitude Control and Energy Storage (ACES) , and SkyPad.

USA-300 likely is a small satellite that was deployed from the X-37B's payload bay shortly after launch.
