✨Celebrating 90 years of the Grumman F3F! On March 20, 1935, the Grumman F3F flew for the first time, becoming the last biplane fighter of the U.S. Navy. Known for its rugged design, powerful Pratt & Whitney R-1535 radial engine, and superior maneuverability, the F3F was a formidable fighter for its time, and set the stage for Grumman’s legendary “Iron Works” reputation. 📼Check out this remarkable footage from when an F3F made a trip to Oshkosh in 1954, 1971, and 1993. #aviation #Grumman #Aviat
