1. This is a thread about the Bristol Beaufighter & how it was the most important (if not the absolute ‘best’) heavy fighter of the SWW. Beaufighter origins go back to the Bristol Type 142 ‘Britain First’ built as a publicity stunt for Daily Mail owner Lord Rothermere in 1935.

2. With a top speed of 278mph, this was considerably faster than the Hawker Fury, which could only manage 207mph. A specification for a fast medium bomber was issued for a revised version of the 142M, named the Blenheim.

3. By the time the war started all-metal monoplane fighters had eclipsed the performance of the Blenheim. Serious shortcomings in operational capabilities of all RAF aircraft were revealed during early wartime aerial activity, leading to heavy losses of aircraft & crews.

4. Lack of defensive armament, armour & self-sealing tanks were added to the problems of looming obsolescence. The huge number of aircraft ordered from shadow factories, along with delays to replacement models, kept the Blenheim in the front line much longer than it should have.

5. Fighter Command had 7 Blenheim IF squadrons at the outbreak of war. These were dual purpose day/night units, but by early 1940 were operating primarily as night fighters. The need to provide cover for east coast convoys led to the formation of 4 ‘trade protection’ squadrons.
