The Starfleet Museum of Deep Space Exploration was a Federation space station and part of the Starfleet Museum.
At some point in its history, replicas of six starships Enterprise were docked around its primary hull as exhibits. They included the Enterprises NX-01, NCC-1701 and its refit version, and the Enterprises B, C and D.
The space shuttle Enterprise OV-101 was also exhibited at the museum. It was tractored into position by a shuttlepod with a rear-mounted emitter. (Ships of the Line 2014)
