From 1942 to 1943, Rehoboth Beach Airport served as a base, designated as Coastal Patrol Base 2, for volunteers with the Civil Air Patrol, who flew aerial patrols using civilian aircraft in support of Army and Navy anti-submarine operations during the Battle of the Atlantic. Two CAP airmen, Captain Hugh R. Sharp of Greenville, Delaware and First Lieutenant Edmond Edwards of Newark Delaware, would go on to be the first civilians to receive the Air Medal after a search and rescue mission on 21 July, 1942 where they rescued one crewmember of another CAP aircraft which crashed at sea.
