USS Perch (AS-6)

USS Perch (AS-6) was a Fulton-class submarine tender of the United States Navy commissioned in 1929 to provide maintenance, logistics, and repair services to submarine squadrons operating in the Atlantic Ocean and Pacific Ocean. Built by William Cramp & Sons and later active in both peacetime and wartime deployments, Perch supported submarine operations through the interwar period and played roles in the early years of World War II before being decommissioned after the conflict.

Design and Construction

Perch was laid down and constructed by William Cramp & Sons at the Philadelphia Naval Shipyard as part of a program to modernize tender support for the United States Atlantic Fleet and later the United States Pacific Fleet. Designed on the Fulton-class plans alongside sister ships such as USS Fulton (AS-11) and USS Holland (AS-3), her machinery included steam turbine propulsion and auxiliary generators to power extensive machine shops, electrical repair facilities, and supply storerooms intended to service classes of R-class submarine and S-class submarine boats. Her hull and superstructure incorporated heavy cranes and davits for handling torpedos, main battery ammunition, and replacement parts for diesel engines and electrical systems, enabling forward deployment with squadrons such as Submarine Squadron 6 and forward bases like Pearl Harbor.

Service History

Upon commissioning in 1929 Perch reported to the United States Atlantic Fleet before transferring to the United States Pacific Fleet as fleet dispositions shifted in the 1930s. She operated between major naval bases including Puget Sound Naval Shipyard, San Diego Naval Base, and Pearl Harbor, conducting repair periods for boats from Submarine Divisions and supporting exercises with units from Fleet Problem maneuvers. During the late 1930s Perch enabled long-range deployments of fleet submarine groups, providing logistic support that extended patrol endurance and readiness, interacting with commands such as Commander, Submarine Force, U.S. Fleet.

World War II Operations

At the outbreak of World War II in the Pacific following the Attack on Pearl Harbor, Perch continued repair and tender duties under wartime conditions, operating from advanced anchorages and tending submarines engaged in patrols against Imperial Japanese Navy shipping. She rotated between forward areas and rear bases, conducting overhauls and emergency repairs on hulls, propulsion plant components, and battery systems for Gato-class submarine, Balao-class submarine, and earlier classes. Her crews collaborated with units from Submarine Squadron 14, Submarine Force Pacific Fleet, and shore installations such as Naval Base Pearl Harbor and Cavite Navy Yard where available, while also coordinating logistics with Service Force, U.S. Pacific Fleet supply vessels and tenders like USS Holland (AS-3). Perch assisted damage control, provisioned torpedoes including Mark 14 torpedo handling, and supported snorkel and sonar upgrades as anti-submarine warfare intensified with escorts from Destroyer Squadron elements. During the later war years Perch transferred between forward anchorage points to support intensified submarine campaigns in the Philippine Sea and around Solomon Islands, enabling extended patrol rotations that contributed to interdiction of Japanese merchant marine logistics.

Postwar Fate and Decommissioning

Following Japan's surrender in 1945 and the cessation of hostilities after Surrender of Japan (1945), Perch aided in postwar drawdown activities, assisting decommissioning overhauls for surplus submarines and facilitating transfer preparations for vessels bound for inactivation at yards such as Mare Island Naval Shipyard and Philadelphia Naval Shipyard. As the United States Navy reorganized its submarine force around newer nuclear-capable platforms and tenders, Perch was slated for decommissioning and transfer to reserve status. She was placed out of commission and struck from the Naval Vessel Register in the immediate postwar years and ultimately disposed of by sale or scrapping in accordance with surplus disposition policies implemented by the United States Maritime Commission.

Awards and Honors

Throughout her career Perch and her crew were eligible for campaign and service recognitions associated with operations in the Pacific Theater, including qualifying service for awards administered by the Department of the Navy for personnel aboard tenders supporting Asiatic-Pacific Campaign operations and the broader American Theater (1939–1945). Individual ships she tended earned combat distinctions while Perch's logistic and repair contributions were acknowledged through unit service credit and campaign streamers awarded under United States military awards and decorations regulations.
