The next step was the need to procure a capable night fighter design.

Recent images reveal a fighter design with substantially larger internal weapons bays.

An earlier attempt at a fighter design proved even less successful.

The performance was impressive, but the last development of this 1935 fighter design had several shortcomings and was not entirely successful.

It remains one of the least known production fighter designs.

In the United States alone, several dozen different fighter designs made it to the prototype stage during the 1950s and 1960s.

During the war, this design served as the basis for some light fighter designs, but these did not enter mass production.
