Deep Space 7

Deep Space 7 is a Federation Starbase operating along the Romulan Neutral Zone. It was built in the late 2360s from the salvaged remains of Deep Space 6, which was destroyed during construction by a freak accident in 2363. Its communications, sensor, and defensive systems all feature state-of-the-art technology. Starfleet Intelligence maintains a significant presence on board.
