I'm all for a Beaufighter, a great historical plane. However in the MA it would sadly be a hangar queen.
Some data:
Performance (Mk X)
Maximum speed - 312 mph (502 km/hr)
Initial climb - 1, 850 feet (564 metres) per minute
Service ceiling - 26,500 feet (8077 metres)
Armament (Mk X)
Four x 20 mm Hispano cannon - fixed in underside of forward fuselage
(initially loaded with 60-round drums, later equipped with belt feed)
One 0.303-inch Browning or Vickers K, manually-aimed, in oberserver's position
(Fighter Command versions in general did not have this manually-aimed gun but had
six x 0.303 Browning machine guns in wings, four in outer starboard wing, two in outer port wing)
One 18"/ 1,605 (728 kg) or 22.5"/ 2,127 lb (954 kg) torpedo
Wing racks for eight rockets or 2 x 1,000 lb bombs
