The Oklahoma City (SSN 723) is the 35th Los Angeles-class attack submarine and the second ship of the United States Navy to be named for Oklahoma City, Oklahoma. The contract to build her was awarded to Newport News Shipbuilding and Dry Dock Company in Newport News, Virginia on August 13, 1981, and her keel was laid down on January 4, 1984. She was christened and launched on November 2, 1985, sponsored by Mrs. Linda M. Nickles, and commissioned on July 9, 1988, with Cmdr. Kevin J. Reardon in command.

November 13, USS Oklahoma City collided with a Norwegian tanker Norman Lady while transiting the western Mediterranean Sea east of the Strait of Gibraltar. No Sailors were injured and there were no leaks of oil from fuel tanks and no threat to the environment, but the submarine sustained damage to her periscope and sail area, and put into La Maddalena, Sardinia, for repairs. The accident occurred in international waters at approximately 1:30 p.m. (GMT).

January 20, 2005 USS Oklahoma City, commanded by Cmdr. Goedon C. Williams, returned to Norfolk after completing a six-month deployment that circumnavigated North America. She deployed to the Pacific Ocean in July 2004, and within three weeks, completed an inter-fleet transfer under the Arctic. In the Pacific, OKC conducted operations in support of national security interests and the global war on terrorism. The submarine completed its circumnavigation of North America by transiting back to the Atlantic through the Panama Canal and returning to Naval Station Norfolk. She is only the third submarine to make the under-ice transit. The first sub to transit from the Atlantic to the Pacific under the Arctic was USS Nautilus (SSN 571) in 1958.

April 20, 2007 USS Oklahoma City took the next step in technological advances this April, adding the Navy’s newest navigational tool to its arsenal. The Voyage Management System (VMS), a combination of digital charts, constant global positioning system fixes, environmental sensors and electronic command and control, will allow the submarine to eliminate many of the constraining aspects of navigation when using paper charts. The digital nautical charts can be downloaded or ordered from the National Geographical Intelligence Agency (NGA) web site along with other data provided by NGA which add needed bottom contour features necessary for safe navigation. SSN 723 is the first submarine to operate on this version of VMS.
