JF may refer to:
The Grumman J2F Duck (company designation G-15) was an American single-engine amphibious biplane. It was used by each major branch of the U.S. armed forces from the mid-1930s until just after World War II, primarily for utility and air-sea rescue duties. It was also used by the Argentine Navy, who took delivery of their first Duck in 1937. After the war, J2F Ducks saw service with independent civilian operators, as well as the armed forces of Colombia and Mexico.
The J2F was an improved version of the earlier JF Duck, with its main difference being a longer float.
The J2F-1 Duck first flew on 2 April 1936, powered by a 750 hp (559 kW) Wright R-1820 Cyclone, and was delivered to the U.S. Navy on the same day. The J2F-2 had a Wright Cyclone engine which was boosted to 790 hp (589 kW). Twenty J2F-3 variants were built in 1939 for use by the Navy as executive transports with plush interiors. Due to pressure of work following the United States entry into the war in 1941, production of the J2F Duck was transferred to the Columbia Aircraft Corp of New York. They produced 330 aircraft for the Navy and U.S. Coast Guard. If standard Navy nomenclature practice had been followed, these would have been designated JL-1s, but it was not, and all Columbia-produced airframes were delivered as J2F-6s.
This is the G. I. Jive
Man alive
It starts with the bugler blowin' reveille over your bed when you arrive
Jack, that's the G. I. Jive
Roodley-toot
Jump in your suit
Make a salute
Boot
After you wash and dress
More or less
You go get your breakfast in a beautiful little caf? they call "The Mess"
Jack, when you convalesce
Outta your seat
Into the street
Make with the feet
Reet
If you're a P-V-T, your duty
Is to salute to L-I-E-U-T
But if you brush the L-I-E-U-T
The M-P makes you K-P on the Q-T
This is the G. I. Jive
Man alive
They give you a private tank that features a little device called "fluid drive"
Jack, after you revive
Chuck all your junk
Back in the trunk
Fall on your bunk
Clunk
This is the G. I. Jive
Man alive
They give you a private tank that features a little device called "fluid drive"
Jack, if you still survive
Chuck all your junk
Back in the trunk
Fall on your bunk
Clunk
Soon you're countin' jeeps
But before you count to five
