The Bristol Company decided to use the existing development and basic structural elements of the Beaufort torpedo bomber in the design of a new long-range fighter, and so the Beaufighter project was born, unique in that it was developed independently from any request by the UK Air Ministry. The designers adopted the wings, undercarriage, and tail design of the Beaufort and created a twin-engine all-metal heavy fighter.
Most of the last mass-produced aircraft in Britain were Beaufighter TF Mk.Xs. This model was a logical continuation and development of the Mk.VIC, had the same Hercules Mk.VI engine, and could carry the standard torpedoes produced in Britain and the United States. The TF letters in the designation stood for “Torpedo Fighter”. The aircraft could also carry a bomb load of 1100 kg, and with the help of the Mk.VIII radar installed in the nose, they were the ideal machines for detecting and destroying surface targets.
In March 1945, over a period of 48 hours, they found and destroyed five German submarines.
Of the 5,928 Beaufighters made in the UK, 2,205 were Mk.Xs.
