Naval Inactive Ship Maintenance Facility

A Naval Inactive Ship Maintenance Facility (NISMF) is a facility owned by the U.S. Navy as a holding facility for decommissioned naval vessels, pending determination of their final fate. All ships in these facilities are inactive, but some are still on the Naval Vessel Register, while others have been struck from that Register.

The ships that have been stricken from the NVR are disposed of by one of several means, including foreign military sale transfer, ship donation as a museum or memorial, domestic dismantling and recycling, artificial reefing, or use as a target vessel. Others are retention assets for possible future reactivation, which have been laid up for long-term preservation and are maintained with minimal maintenance (humidity control, corrosion control, flood/fire watch) should they need to be recalled to active duty.

The Navy has been actively reducing the number of inactive ships, which numbered as many as 195 in 1997, but was down to 49 by the end of 2014.

The Naval Sea Systems Command's Inactive Ships Management Office (INACTSHIPOFF) is based in Portsmouth, Virginia.
