J2F Duck

From Wikipedia, the free encyclopedia

The Grumman J2F Duck was a single-engine amphibious biplane. It was originally designated as the Grumman G-15. It was produced from 1933 to 1945.

The Duck's main pontoon was part of the fuselage, making it a flying boat despite the similarity to a conventional landplane which has been float-equipped. Like the F4F Wildcat, its narrow-tracked landing gear was hand-cranked.

The aircraft was used by both the U.S. Navy and U.S. Coast Guard as utility aircraft for missions including mapping, rescue work, photography, and a target training.
