Grumman J2F Duck – jednosilnikowa, dwupłatowa łódź latająca produkowana w latach 1936 - 1945. Samolot zaprojektowany w zakładach Grummana początkowo otrzymał oznaczenie G-15, ale po przyjęciu go przez US Navy znany był jako J2F Duck.
Samolot był używany przez Marynarkę Wojenną Stanów Zjednoczonych i Straż Wybrzeża Stanów Zjednoczonych jako wielozadaniowy, uniwersalny samolot do rozpoznania, mapowania, robienia zdjęć i misji ratunkowych.

USAAC Roundel 1919-1941.svg
Roundel used by the United States armed forces from 19 August 1919 to 6 May 1942 until red dot removed to avoid confusion with Japanese insignia. Superseded very similar roundel whose colors and proportions differed slightly - the original version having the colors from the US flag, and a center dot 1/3 of the outer radius. This version has a center dot constrained by the inner vertices of the star, a size that does not translate into an even fraction.

US roundel 1942-1943.svg
Roundel used by US armed forces from 6 May 1942 to 28 June 1943 when white bars and a red outline were added as the result of studies which showed that shape was more important than color from a distance.

Roundel used by all US armed forces from 31 July 1943 to 14 January 1947, replacing roundel having red outline, or no outline, but with white bars, and was replaced some nine months before the USAF was formed, by roundel having a single lengthwise red bar inset in white bars (bisecting them), giving the insignia the trio of red-white-red stripes evocative of the non-canton areas of the Flag of the United States.
