USS Pocomoke (AV-9) was a Pocomoke-class seaplane tender, originally built as the SS Exchequer and acquired by the U.S. Navy as the military build-up occurred in the United States just prior to World War II.

When the United States entered World War II in December 1941, Pocomoke was attached to Task Group 4.3 of the Support Force, Atlantic Fleet, stationed at Argentia, Newfoundland.

She tended two patrol planes which scouted waters approaching the harbor searching for German U-boats which threatened convoys carrying desperately needed war material to England.

After returning to the U.S. West Coast for additional supplies, Pocomoke sailed to Pearl Harbor 4 January 1943, then, escorted by USS Breese, proceeded to the Fiji Islands where she unloaded cargo.

On 6 June she embarked men of Patrol Bombing Squadrons VPB-15 and VPB-23 at Espiritu Santo and provided vital tender services in the area until sailing for Pearl Harbor 18 September.

Pocomoke continued her vital services, taking on Marine Night Fighter Squadron 532 (VMF(N)-532) with planes, rolling stock and equipment and sailed via Pearl Harbor to Funafuti Atoll, anchoring there 11 January 1944.

From 11 September 1945 through 1 February 1946, she steamed among the various islands in the Philippine group, dispensing her services, providing supplies, ferrying troops, and operating search patrols wherever needed.
