A TJS satellite that has displayed unusual sub-satellite deployment behavior — releasing smaller objects into nearby orbits during its operational life. This capability could represent testing of inspection, jamming, or proximity operations technologies, or it may relate to hosted payload deployment for intelligence collection. China has not explained these maneuvers, which have been closely tracked by US Space Force and independent analysts.
