USS Topeka (SSN-754)

USS Topeka (SSN-754) is a Los Angeles-class submarine and the third United States Navy vessel to be named for Topeka, Kansas. The contract to build her was awarded to the Electric Boat Division of General Dynamics Corporation in Groton, Connecticut, on 28 November 1983 and her keel was laid down on 13 May 1986. She was launched on 23 January 1988, sponsored by Elizabeth Dole, and commissioned on 21 October 1989.

Topeka and USS Albany (SSN-753) form a unique variant among Los Angeles class submarines. The pressure hulls of both ships were partially manufactured using stronger HY-100, instead of the HY-80 steel used in the manufacturing of all other Los Angeles class submarines. This was done to test construction methods using this steel, which would later be employed in the assembly of the new Seawolf-class submarines. In theory, this permits Albany and Topeka to dive to a slightly greater depth than any other member of the Los Angeles class, though it remains unclear if this ability has ever been tested by either vessel.

History
During New Year's Eve 2000, Topeka straddled the International Date Line, thus was famously "in two millenniums at once".

In October 2002, after completing a Modernization Period in Pearl Harbor Naval Shipyard, Topeka shifted homeport to San Diego, California, from Pearl Harbor.

In December 2012, the submarine began an overhaul at Portsmouth Naval Shipyard. Earlier that same year, she completed a six-month-long deployment in the Western Pacific, covering around 35,000 nautical miles.

In May 2015, after miscellaneous repairs at Pearl Harbor Naval Shipyard, Topeka shifted homeport to Naval Base Guam as part of the U.S. Navy's rebalance of force into the Pacific.

In December 2020, Topeka shifted homeport to Naval Station Pearl Harbor.

Topeka participated in RIMPAC 2022.
