Design

The Bristol Buckingham was designed to replace the Bristol Blenheim.1

The Buckingham was supposed to enter service in 1942 but production didn't start until 1944 due to difficulties with the Centaurus engines.1

Also the Mosquito was able to take the same payload and perform better so it was given the priority.1,2

Prototype

The Buckingham prototypes were first flown on February 4, 1943.1 The first prototype wasn't armed.1 The second prototype was armed.1

The 3rd and 4th prototypes had larger fins.1

Postwar

The Buckmaster T.1 prototype flew on October 27, 1944.1

An order of 400 Buckinghams were ordered.1

  • Prototypes: 41
  • Buckingham: 1191
  • Buckmasters: 1111
  • Production: 19422

  • Buckingham C.1: The next 65 produced were transports.1 Turrets were removed.1,2 A few B.1s were converted to C.1s.1,2
  • Buckmaster T.1: Postwar trainer.1 Had dual controls.1,2 There was no dorsal turret or gondola.1,2 The trainee pilot was on the port side.2

Usage

The Buckingham C.1 transports were primarily used on the flights to Malta and Egypt.1

Postwar
