Destroyer Squadron 23 is a squadron of United States Navy destroyers based out of San Diego, California. The squadron is best known for its actions during World War II, most notably the Battle of Cape St. George, under the command of then-Commodore Arleigh Burke. Currently, the DESRON is assigned to Carrier Strike Group Nine, which includes USS Theodore Roosevelt (CVN-71), USS Chosin (CG-65), USS Lake Erie (CG-70), and Carrier Air Wing Eleven.

The Battle of Cape St. George was a naval battle of the Pacific campaign of World War II fought on 25 November 1943, between Cape St. George, New Ireland, and Buka Island. It was the last engagement of surface ships in the Solomon Islands campaign. During the engagement, a force of five US Navy destroyers led by Captain Arleigh Burke intercepted a similar sized Japanese force that was withdrawing from Buka towards Rabaul, having landed reinforcements on the island. In the ensuing fight, three Japanese destroyers were sunk and one was damaged, with no losses amongst the US forces.
