Commander John Anderson Moore

John Anderson Moore (January 12, 1910 – February 26, 1944) was a United States Navy submarine commander who was killed in action during World War II. He had been awarded three Navy Crosses[1] and a Purple Heart Medal before his death. The U.S. Navy frigate USS John A. Moore (FFG-19) is named in his honor.

Raised in Bisbee, Arizona, Moore had boxed and played soccer at the United States Naval Academy. He served on R- and S-class submarines, before assuming command of the submarine USS Grayback (SS-208) on its last three patrols during 1943–1944. Under the overall command of innovator Charles "Swede" Momsen, Grayback, USS Cero (SS-225), and USS Shad (SS-235) launched the U.S. Navy's first attack against enemy shipping using "wolfpack" tactics. Moore was credited with multiple events of "extraordinary heroism" in repeated forays against Japanese vessels in the East China Sea before being killed during the last of the Grayback's patrols.

It was thought that he only and his crew of 59 were on board the USS Grayback. However, there were 80 souls found to be on board when the sub was discovered.
