The Nausicaan cargo station

A docking arm was a large magnetic extension built into the launch bay of an NX-class starship. The arm was used in docking procedures, such as a shuttlepod landing or departure. Officers aboard the vessel were able to remotely deploy the docking arm from the starship's bridge. (ENT: "Fight or Flight", "Hatchery")

A Nausicaan cargo station built into an asteroid also featured docking arms outside of the base for the Nausicaan ships. In August of 2151, the ECS Fortunate and Enterprise NX-01 discovered this station and were attacked by three Nausicaan raiders which were deployed from these docking arms. (ENT: "Fortunate Son")
