The Vickers 161, also known as the C.O.W Gun Fighter, was one of an odd group of interceptors. It was designed to attack a formation of bombers from below, using a 37mm Coventry Ordnance Works gun to blow them out of the sky.

Only one example of this weird biplane was made as it proved too difficult to mange for a single pilot. However more successful attempts at this concept of interceptor would eventually lead to the BoultonPaul Defiant.

Producing these videos is a hobby of mine. I have a passion for history, and personally own a large collection of books, journals and other texts, and endeavor to do as much research as possible. However if there are any mistakes, please don't hesitate to reach out and correct anything :)
