The USS Amberjack (SS-219) was a Gato-class submarine built for the United States Navy during World War II. Her keel was laid on 15 May 1941 by the Electric Boat Company in Groton, Connecticut. She was launched on 6 March 1942, sponsored by Mrs. Randall Jacobs, and officially commissioned on 19 June 1942. The vessel measured approximately 312 feet in length, with a beam of about 27 feet, and was powered by diesel engines and electric motors suitable for submerged operations. Following her shakedown training off New London and Newport, Amberjack transited the Panama Canal in August 1942 to reach Pearl Harbor, where she prepared for combat. Her first war patrol began on 3 September 1942, targeting Japanese shipping in the Solomon Islands area. During this patrol, she successfully sank the Shirogane Maru, a Japanese cargo ship, by firing torpedoes that struck her in Bougainville Strait. Amberjack also engaged other targets, including a large Japanese cruiser and various freighters, with mixed success. Notable actions included damaging the Japanese cargo ship Senkai Maru and damaging the tankers Tonan Maru II, which was later salvaged and returned to service. Throughout her service, Amberjack conducted multiple patrols, operating off New Ireland, Bougainville, and Rabaul. She engaged enemy vessels with torpedoes, fired on convoy targets, and performed reconnaissance and patrol duties. Her operational history included encounters with Japanese destroyers and submarines, as well as surviving depth charge attacks that caused minor damage but no critical failures. Her last radio report was on 14 February 1943, describing her being forced down by destroyers and capturing an enemy aviator. She was presumed lost after failing to return to base by 22 March 1943. Enemy reports suggest that Amberjack was likely sunk in an attack on 16 February 1943, when Japanese torpedo boats and a patrol plane attacked a submarine in her area, leaving heavy oil and hull debris at the scene. She was credited with sinking three ships totaling approximately 28,600 tons and damaging two others. Her loss marked her as one of the many wartime U.S. submarines engaged in critical operations in the Pacific theater, exemplifying the dangerous and vital role of submarines in naval warfare.
