USS Spirit (NX-79995)

The USS Spirit (NX-79995) was a Federation Starfleet starship in service in the late-24th century, or beyond, which utilized quantum slipstream drive propulsion technology, in addition warp engines.

The class was relatively small, approximately four decks high, and featured a tapered streamline hull with small wings near the front of the vessel and tailfin at the rear. The ship's warp nacelles were suspended on pylons extending out and down from the top of the rear of the vessel. (ST calendar: Ships of the Line 2009)

Background
This ship has so far only appeared as an image titled "Around the Quadrant in Eighty Days" in the 2009 Ships of the Line calendar, and as a result only information which can be obtained visually is available.

In a post on the TrekBBS the artist Mark Rademaker provided some specifications for the vessel which he identifies as a member of the Spirit-class: The vessel is supposedly in service in the 2390s, as a test-bed for quantum slipstream technology brought back from the Delta Quadrant by the USS Voyager. It was designated an explorer scout, was approximately one-hundred-and-twenty meters long and had a crew compliment of between twelve and thirty personnel. He describes the class as having eight rapid fire pulse phaser outputs, each capable of firing in three different modes. The class also features a small shuttlebay with a drop down door that also functions as a landing platform.
