USS Walter Adams (SP-400): From Fishing Trawler to Naval Patrol Vessel
During the height of World War I, the United States Navy expanded its fleet by chartering civilian vessels to bolster coastal defenses. One such vessel was the USS Walter Adams, a wooden-hulled steam fishing trawler that transitioned from the commercial fishing industry to military service as a patrol vessel.
Key Facts
- Original Role: Private steam fishing trawler (SS Walter Adams).
- Naval Designation: SP-400 (also listed as ID-400).
- Service Period: Commissioned October 1, 1918; decommissioned January 10, 1919.
- Operational Area: 6th Naval District, operating primarily out of Charleston, South Carolina.
- Builder: Robert Palmer and Son of Noank, Connecticut.
Origins and Construction
The vessel began its life as the SS Walter Adams, constructed in 1890 by the renowned shipbuilders Robert Palmer and Son in Noank, Connecticut. As a steam fishing trawler, it was designed for durability and utility. The ship underwent a significant rebuild in 1898 to maintain its operational efficiency in the demanding environment of commercial fishing.
As the United States entered World War I, the Navy sought out civilian ships capable of coastal patrol and support. The SS Walter Adams was inspected for potential naval service twice: first in March 1917 and again in June 1918. Following these evaluations, the Navy chartered the vessel on June 23, 1918.
Naval Service and Designation
The ship was officially commissioned as the USS Walter Adams on October 1, 1918. Its designation presents an interesting historical detail: while photographs show "SP-400" painted on the bow—a prefix typically used for Section Patrol boats—official data cards list it as "ID-400." The "ID" prefix was generally reserved for cargo ships, tankers, and transports pressed into service from the civilian sector.
Assigned to the 6th Naval District, the USS Walter Adams operated locally out of Charleston, South Carolina. While detailed logs of its daily activities are unavailable, historians believe the vessel likely conducted practice minesweeping operations, a common task for converted trawlers during the war.

Decommissioning and Return to Civilian Life
The naval career of the USS Walter Adams was brief, coinciding with the end of World War I. On January 10, 1919, the vessel was decommissioned at the Customs House Dock in Wilmington, North Carolina. On that same day, it was struck from the Navy List and returned to its original owners, resuming its identity as the private fishing trawler SS Walter Adams.
