FIRST PREVIEW COMING SOON
The JF/J2F "Duck" was one of those military workhorses moving around in the background before and during WWII which did a tremendous job but never got the publicity of its' more glamorous teammates. Some said the Duck could be more aptly named the "Ugly Duckling". Be that as it may; when no other bomber could be found, it carried bombs; when no other transport could be found, it transported; when no other photo plane could be found, it photographed and when no other rescuer could be found, it rescued. When it came to "Utility Craft", the JF/J2F was the definitive.
The Duck originated with designs and production aircraft made by Loening Aeronautical Engineering Corporation. When Loening was taken over by Curtiss-Wright in 1929, several key employees of the former Loening Aeronautical (among them; Leroy Grumman) formed the Grumman Aircraft Engineering Corporation which was financed by Grover Loening. In 1928, even before Curtiss-Wright took over Grover Loening Aeronautical Engineering, Loening formed the Grover Loening Aircraft Company. In 1931, Grover Loening Aircraft submitted their XO2L-1 design to the U.S. Navy for its new "Utility" category. The Navy was intrigued with the design, but as Loening had no production facilities, he was directed to Grumman. Grumman accepted the craft as "Design 7". After modifications to make it more easily produced, Grumman submitted the specifications to the Navy in 1932 and the Navy accepted it as the XJF-1.
The JF-1 Duck was an extremely rugged aircraft (as were all Ducks). For example, on December 7, 1937 Marine Sergeant Bernard Belcher flipped his aircraft completely upside down while trying to land in a cross-wind (a particularly hazardous undertaking in a Duck). And, though the JF-1 dug its nose into the ground and somersaulted, the only damage sustained was a few wrinkles in the top of the rudder and fin. Sergeant Belcher was uninjured.
Though the JF-2 looked very similar to the JF-1, there were subtle differences, the most obvious being the installation of a loop radio direction finding antenna to the rear of the canopy. This antenna was removed whenever the Browning .30 caliber machine gun was mounted so as not to interfere with the field of fire. A somewhat less noticeable difference was the change to a Wright 1820 "Cyclone" engine which resulted in a much narrower chord for the engine cowling. Horsepower was the same as the Pratt-Whitney, and the reason for the change is somewhat obscure. In all probability the Wright engine was more readily available at the time. The Duck set a world speed record for single engine amphibians on Wednesday, December 4, 1935 when a JF-2 (Serial #0266) was flown near Quantico, VA at a speed of 191 mph (307.39 kph). A total of 14 JF-2s were built. The JF-2 Duck was built exclusively for the Coast Guard, and thus the tail hook of the JF-1 was deleted. Most of the JF-2s were later transferred to the Navy and Marines. |
