Los Angeles-class fast-attack submarines assigned to Commander, Submarine Squadron (CSS) 15 transit Apra Harbor, depart Naval Base Guam and moor pierside during operations in 2020. CSS-15 is responsible for providing training, material, and personnel readiness support to four Los Angeles-class fast attack submarine commands located on Polaris Point at Naval Base Guam. Submarine Squadron 15 (also known as SUBRON 15) is a squadron of submarines of the United States Navy based at Naval Base Guam.
Submarine Squadron Fifteen was established on 1 September 1963 at Pearl Harbor, Hawaii. The squadron was formed to take over responsibility for the submarine-based nuclear deterrent in the Pacific from Submarine Squadron 1, which at the time operated submarines carrying the Regulus cruise missile. Four of the seven submarines scheduled for this squadron were being built at the time, and the submarine tender USS Proteus was undergoing overhaul at the Charleston Naval Shipyard.
During the first few months, the squadron established headquarters at Pearl Harbor and laid groundwork for Polaris Operations in the Pacific. One of the most difficult tasks was establishing and executing the vast training program required for the Blue and Gold crews of each submarine. To meet this requirement, close cooperation with the officers in charge of various schools throughout the nation and Commanding Officers and crewmen of the submarines was necessary.
Submarine Squadron 15 consists of four Los Angeles-class fast attack submarines (SSNs):
USS Key West (SSN 722)
USS Oklahoma City (SSN 723)
USS Topeka (SSN 754)
USS Asheville (SSN 758)
