The USS Aquila (PHM-4) was the second vessel of the Pegasus-class hydrofoils operated by the United States Navy, designed for high-speed mobility and armed with a potent, size-appropriate weaponry. Laid down on July 10, 1979, by Boeing Marine Systems in Seattle, Washington, she was launched on September 16, 1981, and commissioned at Puget Sound Naval Shipyard on June 26, 1982. The vessel's construction emphasized speed and agility, characteristic of the hydrofoil class, enabling rapid deployment and tactical versatility. Aquila's early operational history involved transit from Bremerton, Washington, to her home port of Key West, Florida, in July 1982, escorted by other naval ships through the Panama Canal. She conducted shakedown and training operations out of Key West, engaging in routine exercises and special missions, including operations in the Caribbean Sea and patrol duties around Grenada during the mid-1980s. Notably, she participated in efforts to interdict drug trafficking and tested joint operational capabilities with frigates and other vessels. Throughout her service, Aquila was involved in various exercises, including FLEETEX 1-86 and Operation "Ocean Venture 86," simulating fleet attacks in the Caribbean. Her operational profile also included testing with aircraft, such as A-7E Corsair II jets, and conducting special tests with other naval units. Her role was primarily focused on rapid response, patrol, and interdiction missions, reflecting her design as a high-speed hydrofoil. A significant and tragic incident occurred in April 1991 when Aquila struck a whale in the Straits of Florida, causing severe hull damage, flooding, and crew injuries. The impact warped her stern hull, damaged her communication systems, and required emergency salvage efforts, including assistance from a Coast Guard Falcon aircraft. Despite this damage, Aquila continued her service until her decommissioning in 1993 and subsequent sale in 1996. Aquila's operational history highlights her role as a fast, agile naval asset capable of performing diverse missions from patrol to specialized exercises, exemplifying the unique capabilities of the Pegasus-class hydrofoils during the Cold War era.
