Design

The Avro Type 679 Manchester was designed to meet a 1936 specification for a medium/heavy bomber that could go at high speeds with powered turrets.

After initial flight trials the span was increased by three meters. A fin was added between the tail fins, but this was removed in the Manchester Mk IA.

40% of the Manchesters were lost in operations and 25% in accidents.

Crew

The pilot and engineer sat next to each other in the cockpit. There was an astrodome for the navigator to take celestial measurements for navigation.

The nose gunner, also the bomb aimer, sat in a powered turret. Typically during night operations the nose gunner didn't see much combat.

The rear gunner, especially at night, saw the most action and would tell the pilot what evasive action to take when a night fighter was attacking them.

Engines

The 24 cylinder X configured engine was basically two Peregrine V-12 blocks attacked to the same crankshaft.

Due to flaws in the airframe and the failure of the Rolls-Royce Vulture engine it wasn't a big success in combat. The Vulture would often overheat.

The engines were down rated to 1,500 HP in the hopes of reducing the overheating.

Prototype

The prototype first flew in July 25, 1939. The next prototype flew in 1940.

The second prototype had extended wings and a third fin to increase stability.

Production

An order for 200 was given by the Air Ministry. This was later raised to 400.

Avro and Metropolitan-Vickers produced the Manchester.

  • Prototype: 2
  • Manchester: 199
  • Total: 201, 202

Variants

  • Avro 679: Avro's designation.
  • Manchester Mk I: Had third tail fin.
  • Manchester Mk IA: Had new horizontal tail surfaces.

Usage

In November 1940 the No. 207 Squadron was the first to have the Manchester. It's first mission was in February 1941. Eventually nine squadrons and one flight of Coastal Command received the Manchesters.

Manchesters took part in the first 1,000 bomber raid on Cologne.

Bomber Command last used the Manchester in the attack on Bremen on the night of June 25 and June 26, 1942.
