This Fighter is used by Starfleet only and is a standard, larger version of later interceptors developed by Starfleet. Large numbers of these ships were used by Starfleet in the Dominion War. During Operation Return, eight successive waves of fighters were sent to attack the Cardassian ships of a Dominion fleet, hoping to provoke them into breaking formation and creating an opening for the Federation fleet.
The attack fighter was capable of carrying an impressive arsenal. When used by Starfleet in 2374, the ships had several forward torpedo launchers and at least one phaser bank with two forward emitters.
