The Vickers Wellington suggests a possible starting point for a turret night fighter with more room and power than a small single-engine aircraft. Its existing turrets prompt the idea of fitting an early medium bomber or twin-engine heavy bomber with 20 mm cannon turrets. The proposed starting point is one of those twin-engine types, before the later four-engine bombers. With radar, a converted aircraft might loiter and engage targets through the turrets' wide firing arcs. This is an imagined conversion, and it probably would not work as envisaged. The attraction of all-around fire still depends on what the aircraft and available technology can support.

A Wellington-type bomber with 20 mm cannon turrets and radar is an appealing night-fighter thought experiment, though it probably would not work as imagined.
