FSC 1990: Miscellaneous Vessels

Federal Supply Class (FSC) 1990 covers miscellaneous military vessels not classified under more specific FSC codes. NSNs in this class support DLA and NAVSUP fleet management and lifecycle parts provisioning.

These specialty vessels perform dredging, survey, ice breaking, and other support roles. They round out the fleet with mission-specific watercraft.

Common types include dredges, survey ships, ice breakers, and other specialty watercraft. Hulls and systems are built to applicable marine and NAVSEA standards.
