USS Surfbird (ADG-383)

• Unique Role: USS Surfbird (ADG-383) was originally commissioned as a minesweeper, USS YMS-271, before being converted into a degaussing ship, a rare and specialized role in the U.S. Navy. • World War II Service: As YMS-271, she participated in minesweeping operations during World War II, supporting the liberation of the Philippines and operations around Okinawa. • Re-designation: In 1947, the vessel was reclassified as AG-383 and later as ADG-383, reflecting her new role in degaussing (reducing a ship’s magnetic signature to defend against magnetic mines). • Korean War Involvement: Surfbird provided vital degaussing services to naval vessels operating in the dangerous waters of the Korean peninsula during the Korean War. • Vietnam War Operations: During the Vietnam War, she served as the only degaussing ship in the Western Pacific, supporting U.S. and allied ships in the region. • Unusual Nickname: Due to her specialized mission and uncommon ship type, Surfbird was sometimes referred to as the "Magnet Ship" by sailors. • Longest Serving Degaussing Ship: USS Surfbird was the longest-serving degaussing ship in the U.S. Navy, from her conversion in 1954 until her decommissioning in 1975. • International Service: After decommissioning, Surfbird was transferred to the Philippine Navy, where she continued service as RPS Mangyan (AG-67). • Distinctive Appearance: The ship featured large degaussing coils on her hull, making her instantly recognizable compared to other support vessels. • Decorations and Awards: Over her career, Surfbird earned several commendations, including the Asiatic-Pacific Campaign Medal, the Korean Service Medal, and the Vietnam Service Medal.
