The Bendix-Stromberg pressure carburetor is a more or less conventional carburetor design in most respects, in that all of the air and fuel control systems are present, but in a modified form. During the Blitz of 1940-41 the AI equipped night fighters were learning how to use their new equipment, but although they were not yet fully effective, their presence in the air was reassuring.

A great number of these engines were Mk.24s, and these were given the commercial mark number 500. This required the addition of an “arrow head” aerial on the nose, with the radar scope back in the operator’s position.
