In the spin-off TV series: "Star Trek: Voyager", what class of starship is the eponymous USS Voyager?
The Intrepid Class Starship USS Voyager was constructed at the Utopia Planitia Fleet Yards orbiting Mars and was launched from Earth Station McKinley on stardate 48038.5 in 2371.
With a length of 343m, width of 116m and a mass of 700,000 tonnes, it is a lot smaller than the Galaxy Class Enterprise featured in "Star Trek The Next Generation"

The vessel was also the first to test the class 9 warp drive in deep space.
