Federation Other Ships Database - Four-Nacelled Defiant Pathfinder

	History:
	Specialized high-warp courier vehicles can be employed for critical missions and are able to cover the 50.3-light-year distance between the station and the UFP inner perimeter within six days. This is equivalent to Warp 9.92, and is accomplished by using alternating twin matter-antimatter reaction cores and nacelle pairs. A modified four-engine version of the Defiant pathfinder spaceframe has proven successful in surpassing the 1,000 light-year/year efficiency barrier. Star Trek Deep Space Nine : Technical Manual
