Grumman JF Duck [p 1 ] byl americký jednomotorový obojživelný dvouplošník vyráběný v 30. letech 20. století společností Grumman pro Námořnictvo Spojených států amerických.
The Grumman JF "Duck" was an American single-engine amphibious biplane built by Grumman for the United States Navy during the 1930s. The J2F Duck was an improved version of the JF, with its main difference being a longer float. [1 ]
The Duck was the first in a long line of seaplanes built by Grumman Aircraft. It was based on an earlier amphibian, designed and built by Grover Loening.
The Grumman J2F Duck formed the backbone of America’s over water utility squadrons from 1934 until beyond WWII, setting various aviation records during this service.
