Delta Class Runabout
The Delta class was created from the efforts of the crew of the USS Voyager to establish a new, formidable and multi-purpose small craft that could perform tasks well above and beyond that of the Intrepid class' standard shuttlecraft as they suffered from being cramped, short-ranged and limited in capabilities; hampering Voyager's efforts to get home from their estimated 70+ year journey through the Delta Quadrant.
When Voyager returned to the Alpha Quadrant, the Starfleet Corps of Engineers immediately began to implement the design with a few upgrades to the Starfleet systems that Voyager didn't have during the ship's construction. Although somewhat resource-intensive for a runabout, it paid itself off two-fold in its usefulness and abilities. Over the next twenty years they remained a popular choice aboard exploration vessels, though they never truly supplanted the more adaptable and less maintenance-intensive Danube-class.
