The USCGC Spencer (WMEC-905) is a United States Coast Guard medium endurance cutter constructed at Robert Derecktor Shipyard Incorporated in Middletown, Rhode Island, with her keel laid on June 26, 1982. Launched on April 17, 1984, and commissioned on June 28, 1986, she is named after John Canfield Spencer, a former Secretary of the Treasury. Designed for law enforcement, search and rescue, and maritime security, Spencer features a robust build suited for extended missions. Throughout her service, Spencer has been actively engaged in a variety of operations that highlight her versatility. In 1987, she conducted a law enforcement patrol resulting in the arrest of 23 individuals and the seizure of over 46,000 pounds of marijuana. During a 1989 south patrol, she rescued and repatriated 538 Haitian migrants and later seized a Panamanian freighter carrying 438 kilograms of cocaine. In 1991, Spencer notably towed the disabled U.S. Navy frigate W.S. Sims, a vessel twice her size, to safety, demonstrating her towing capability and seamanship. Spencer also played a significant role in humanitarian efforts, including participating in the search for a missing Air National Guard pararescueman during the 1991 Perfect Storm. She was on-scene during the 1993 sinking of the ferry Neptune, where she coordinated recovery operations for victims and survivors, rescuing over 1,700 Haitian migrants in subsequent patrols, including a remarkable rescue of 544 individuals on July 4, 1994. She also facilitated the repatriation of migrants from Guantanamo Bay and was part of Fleet Week 1995, showcasing her to the public. Her operational record includes seizing large quantities of narcotics—such as 3,905 pounds of cocaine off Honduras in 1997 and 1,800 kilograms off Venezuela—conducting rescue operations during severe storms, and overseeing the response to the EgyptAir Flight 990 crash in 1999. As of 2023, Spencer is undergoing a significant overhaul at the Coast Guard Yard under the Service Life Extension Program (SLEP), which aims to extend her operational life by up to ten years through equipment upgrades, including replacing her main diesel engines with new ALCO 251 engines, and overhauling her weapons, electrical, and hull systems. She is scheduled to return to service in March 2025, continuing her vital maritime missions.
