The USS Matanzas (AVP-46) was a proposed United States Navy seaplane tender that was ultimately never constructed. She was intended to be part of the Barnegat-class, a series of small seaplane tenders designed during the early 1940s to support naval aviation operations. The class comprised 41 ships, with Matanzas designated as AVP-46. She was to have been built at the Lake Washington Shipyard in Houghton, Washington. The contract for her construction was awarded on 14 April 1942, indicating the Navy's initial intent to expand its support fleet for seaplane operations during World War II. She was assigned the name Magothy on 23 August 1942. However, by the spring of 1943, the Navy reassessed its requirements and determined that the number of planned seaplane tenders was excessive. As a result, the Navy decided to repurpose some ships—converting four of the Barnegat-class vessels into motor torpedo boat tenders and one into a catapult training ship. Additionally, the Navy canceled six ships in the class before construction could commence, reallocating resources such as diesel engines for other wartime needs, like escort vessels and amphibious landing craft. Ultimately, the contract for AVP-46 was canceled on 29 April 1943, making her one of the final two ships in the class to be canceled before construction began. As a result, the USS Matanzas never saw service or physical construction, and her maritime significance remains as part of the broader wartime planning adjustments that shaped U.S. naval logistics during World War II. Her story reflects the shifting priorities and resource allocations of the U.S. Navy during a critical period of naval expansion and modernization.
