1. Грюмман G-21 Гъска е амфибийна летяща лодка, проектирана от Grumman, за да служи като осемместен "пътуващ" самолет за бизнесмени в района на Лонг Айлънд. Goose е първият моноплан на Grumman, който лети, първият двумоторен самолет и първият самолет, който влиза в експлоатация на търговски авиокомпании. По време на Втората световна война гъската се превръща в ефективен транспорт за американските военни (включително бреговата охрана на САЩ), както и служи с много други военновъздушни сили. По време на военните действия гъската поема все по-голям брой бойни и тренировъчни роли.

General Characteristics and Role

The Grumman G-21 Goose is an American amphibious aircraft developed in the mid-1930s. It was the first monoplane designed by Grumman to enter commercial service. Originally built as a comfortable “commuter” for wealthy businessmen in the Long Island area who needed a reliable way to fly between their estates and New York City, the Goose quickly proved its versatility. Its ability to land on both water and land (thanks to its retractable landing gear) made it highly valued. During World War II, the Goose was adopted by the US military (as the JRF in the Navy/Coast Guard and OA-9 in the Army Air Forces) and the UK’s Royal Air Force for roles including anti-submarine patrol, search and rescue (SAR), and utility transport.
