Grumman G-21 Goose

The Grumman G‑21 Goose is an iconic American amphibious aircraft that first flew in 1937 and entered production just before World War II. Conceived by Grumman’s chief designer, Leroy Grumman, the Goose was designed to meet the Navy’s need for a rugged, short‑range transport capable of operating from both water and rough airstrips. Powered by two radial engines—initially the Wright R‑1820 and later the Pratt & Whitney R‑985—the high‑wing monoplane featured a robust steel tube fuselage, retractable landing gear, and a distinctive gull‑wing shape that provided excellent water clearance for the propellers. Its spacious cabin accommodated up to eight passengers or cargo, while the amphibious capability made it a favorite for remote operations, mail service, and military liaison duties. During WWII the Goose served the U.S. armed forces in the Pacific and Atlantic, performing reconnaissance, rescue, and transport missions, and it continued in civilian roles for decades after the war. The aircraft’s reliability, versatility, and distinctive design have cemented its legacy as a pioneering amphibian, influencing subsequent seaplane development and remaining beloved by enthusiasts and collectors worldwide.
