The vessel is being developed under the program title Littoral Surface Craft-Experimental (LSC(X)) with a hull type designation Fast Sea Frame.

With twin gas turbine engines, quad water jets, and streamlined hulls, Sea Fighter is capable of speeds of 50 knots (90 km/h) and greater.

A special deck-lighting system has been developed for Sea Fighter using low-intensity green lighting around the vessel's edges and helipads.

This lighting is particularly effective when using night-vision goggles, making landings on the vessel easier than on conventional warships, even at the higher speeds in which Sea Fighter operates.

The bridge control stations incorporate glass displays using the modern navigational aids to assist Sea Fighter in patrolling coastal areas while operating at high speed.

The first vessel of the type (FSF 1) was constructed at the Nichols Bros. Boat Builders shipyard at Freeland, Washington, under contract to Titan Corporation, a subsidiary of L-3 Communications.

Sea Fighter is destined for employment by the Office of Naval Research as a testbed for technologies related to the Navy's littoral combat ship effort, as well as direct testing of the hull design.

with regard to the use of aluminium alloys almost exclusively in the construction of Sea Fighter's hull, as well as future vessels based on the design.

[9] Additionally galvanic corrosion may result between the aluminum hull and steel fittings, as happened to the littoral combat ship USS Independence.
