The USS Canopus (AS-34) was a Simon Lake-class submarine tender commissioned into the United States Navy in 1965 and decommissioned in 1994, serving for nearly three decades. Built by Ingalls Shipbuilding in Pascagoula, Mississippi, her keel was laid on March 2, 1964, and she was launched on February 12, 1965. Remarkably, she was delivered to the Navy in record time on October 25, 1965, and commissioned shortly thereafter on November 4, 1965. Designed to support Polaris missile submarines, Canopus was equipped to repair and refit submarines armed with ballistic missiles. Her early service included visits to the Caribbean for shakedown training and subsequent deployment to the Cooper River FBM Replenishment Site, where she began refitting submarines of Submarine Squadron 18. In October 1966, she deployed to Rota, Spain, assuming duties with Submarine Squadron 16 and became notable for conducting more Polaris refits than any other tender in her timeframe. In 1969, she underwent an extensive overhaul at Bremerton, Washington, which enabled her to support the new Poseidon missile system, making her the first U.S. Navy tender capable of refitting submarines with this advanced weaponry. She then operated from Holy Loch, Scotland, from 1970 until 1975, where she played a vital role in submarine maintenance, earning multiple awards, including the Ney Award and the Navy Unit Commendation. Throughout her service, Canopus underwent multiple overhauls and supported various submarine squadrons, including operations at Charleston Naval Shipyard and Kings Bay, Georgia. Her service included drills, refits, and logistical support for ballistic missile submarines during the Cold War era. She was decommissioned in October 1994, after which plans for her scrapping in the United Kingdom faced controversy due to environmental concerns. Ultimately, she was scrapped at Able UK in Hartlepool in 2010. The USS Canopus remains a significant vessel for her role in submarine support and missile refit operations during her active years.
