Yellowstone class

The was a type of Starfleet runabout first deployed in the early 25th century.

History
The Yellowstone-class was envisioned as a successor to the venerable of the 2360s and shared many of its predecessor's systems. It began pre-production in the mid-2390s and the first units entered service in 2402.

In February 2409, 42 Yellowstone-class runabouts were delivered to the fledgling Romulan Republic on New Romulus as part of a military aid package and assigned to various Romulan Republican Force ships and installations.

In July 2409, upon receiving command of the unfinished USS Bajor, Captain Kanril Eleya requested a runabout be added to her ship's auxiliary craft complement. The Yellowstone-class USS Glyrhond was assigned to the vessel. Kanril would later have the runabout modified to mimic her ship's warp signature to hide her entry into the from Orion Syndicate forces. 

Technical data
The Yellowstone-class runabout was equipped with a standard tractor beam capable of being used for a warp tow of other vessels.

The class featured an experimental impulse engine powered by. Pilots quickly learned that this could be turned into a defensive weapon by releasing the gas from the nacelle vents, producing a cloud of plasma that disrupted the warp drives on other vessels.
