Title: Grumman G-21 Goose

The Grumman G-21 Goose was the first Grumman twin engined amphibian and first flew in 1937. Initially a flying yacht for millionaires it soon attracted the attention of the military. The USAAF used the aircraft as the OA-9 as a general utility aircraft. The US Navy and US Coast Guard used the JRF-4 and JRF-5 as utility, anti-submarine and rescue aircraft. The aircraft was also used by the RCAF and the Royal Navy. A total of 345 were built between 1937 and 1945. After WW2 the aircraft were used exclusively by civilian companies.
