Sentry (DOK-474) Space Station

Name: Sentry (DOK-474) Space Station

This space station is designed to serve as an orbital outpost supporting future crew landing missions on the Moon, Mars, and Venus. Its main propulsion is achieved by a block of four Novedechivnyy KH-034V bimodal gas-core nuclear thermal engines, using hydrogen as propellant. For station-keeping, the station is equipped with four Novedechivnyy KH-0789 resistojet vernier engines.
The station is equipped with a 640 kW solar array with an energy conversion efficiency of up to 40%.
It is also outfitted with five Ikarus++ class Radio-Laser Docking ports as well as four fold-out docking attachment arms. It is also equipped with two large 20-meter magnetometer booms, for advanced magnetic field studies from orbit.
