5. Northrop F-5 – U.S.A.
We have a few prototypes of a light supersonic jet fighter on hand. The Northrop F-5 is known for its simple, low-maintenance design, which allows it to fly and land quickly. In 1962, it was built for the first time. It was also widely exported and played an important part in the Allies’ military. It is still used as a training aircraft in the United States! This is a hypersonic fighter jet capable of reaching speeds of over 1,000 mph.
