context_page_description: The Avro Type 694 Lincoln is a British four-engined heavy bomber, which first flew on 9 June 1944. Developed from the Avro Lancaster, the first Lincoln variants were initially known as the Lancaster IV and V; these were renamed Lincoln I and II. It was the last piston-engined bomber operated by the Royal Air Force.
  The Lincoln attained operational status in August 1945. It had been initially assigned to units of the Tiger Force, a Commonwealth heavy bomber force which had been intended to play a role in the closing stages of the Second World War by participating in the Japan campaign with operations against the Japanese mainland; the war ended before the Lincoln went into action. Production of the type proceeded and the type was adopted in quantity, allowing it to complement and progressively replace the preceding Lancaster in RAF service during the late 1940s.
  The Lincoln was deployed on operations during the 1950s. RAF squadrons equipped with the type were used as part of Britain's action against guerrilla fighters during the Mau Mau Uprising in Kenya; the RAF and the Royal Australian Air Force operated the Lincoln during the Malayan Emergency.
