Vice Admiral Allan Rockwell McCann, (September 20, 1896 – February 22, 1978) was a United States Navy officer who served in World War I and World War II.
Admiral McCann attended Mark Hopkins Grammar School and Drury High School in North Adams before his appointment to the United States Naval Academy from the First District of Massachusetts in 1913. Graduated and commissioned ensign in March 1917, he was assigned to USS Kansas (BB-21) on which he served throughout World War I and until September 1919. Following instruction in submarines aboard USS Fulton (AS-1) at the Submarine Base, New London, Connecticut, he joined USS K-6 (SS-37) in January 1920, serving in command of that submarine from May to September of that year. Assigned duty in connection with fitting out USS S-19 (SS-124), he was detached in January 1921 before the commissioning of that submarine. He subsequently commanded the submarines USS N-4 (SS-56) and USS L-3 (SS-42) until June 1922. He transferred to USS R-21 (SS-98) at Coco Solo, Canal Zone, serving in command of that submarine until she was decommissioned in June 1924.
In July 1924, returning to the Submarine Base at New London, he served as an instructor in Diesel Engineering for one year, assigned to USS Chewink (AM-39). He then was transferred to duty as Chief Engineer and Repair Officer of that Base. In November 1925, he was assigned additional duty as technical adviser to the Peruvian Naval Commission at the Electric Boat Company, Groton, Connecticut, and when detached in October 1926, he commanded the submarine USS S-46 (SS-157), based on Coco Solo, Canal Zone, until May 1929. He then served in the Design Division, later in the Maintenance Division, Bureau of Construction and Repair (now Bureau of Ships), Navy Department, Washington, DC, for two years, July 1929 – 1931. During that tour of duty he was assigned to diving operations in connection with development of submarine escape apparatus, and was in charge of the development of a submarine rescue chamber, which bears his name, "The McCann Submarine Rescue Chamber". Additionally he was assigned as Liaison Officer / Engineer when the submarine USS O-12 (SS-73) was converted for use in the under ice attempt to circumnavigate the Arctic Ice cap and voyage to the North Pole. Modifications to the submarine were extensive, and contained innovations of a telescoping conning tower, an ice drill, an incorporated diving bell and an Air Lock, designed by Simon Lake. The submarine was designated Nautilus and leased for one dollar to Lake and Danenhower, Inc., of Bridgeport, Connecticut, for use on Hubert Wilkins's and Lincoln Ellsworth's Arctic Expedition.
