General Characteristics

The Avro Lincoln was a British four-engined heavy bomber developed from the highly successful Avro Lancaster to meet Air Ministry Specification B.14/43 for a high-altitude, long-range bomber. Initially designated the Lancaster Mk IV and Mk V, the differences in its enlarged fuselage and longer, stronger wings led to it being given the new name Avro Lincoln. The Lincoln II variant was the main production model, serving as the last piston-engined bomber operated by the Royal Air Force (RAF). Although designed to participate in the final stages of the war against Japan as part of the “Tiger Force,” the war ended before it saw combat, leaving it as a primary RAF bomber throughout the 1950s.

Powerplant and Performance

  • Engine: 4 x Rolls-Royce Merlin 66, 68A, or 300 V-12 liquid-cooled piston engines.
  • Power Output (each): Approximately 1,305 kW (1,750 hp).
  • Maximum Speed: 499 km/h (310 mph) at altitude.
  • Cruise Speed: 346 km/h (215 mph).
  • Service Ceiling: 9,300 m (30,500 ft).
  • Maximum Range (Light Bomb Load): Up to 7,160 km (4,450 miles).
  • Design Note: The higher aspect ratio wings and two-stage supercharged engines (Rolls-Royce or Packard-built) gave it better performance at high altitudes and significantly longer range than the Lancaster.

Armament and Ordnance

  • Nose Turret: 2 x 12.7 mm (.50 in) M2 Browning machine guns (Boulton Paul Type F).
  • Dorsal Turret: 2 x 20 mm Hispano Mk. IV or Mk. V cannons (Bristol B.17).

  • Operational History: Saw action in the 1950s against insurgents during the Malayan Emergency and the Mau Mau Uprising in Kenya. Its airframe was also the basis for the **Avro Shackleton** maritime patrol aircraft.
