Defiant, U.S.S. (NX-74205)

The class ship of its type is the only one produced as a compact yet heavily armed escort ship to meet the Borg threat, with no scientific or other extras save what is needed for combat.

Designed partly by Commander Sisko from Utopia Planetia and then mothballed in the Sol system, Sisko returned to Deep Space Nine with it in 2371 to help meet the Dominion.
