Developed fromVickers Vimy

The Vickers Virginia was a biplane heavy bomber of the British Royal Air Force, developed from the Vickers Vimy.

Design and development

Work on the Virginia was started in 1920, as a replacement for the Vimy. Two prototypes were ordered on 13 January 1921, with an additional two prototypes ordered in September 1922.[1] The Virginia resembled the Vimy but notably had a lowered front gunner's position, providing the pilot with a greater field of view, 20 ft (6 m) greater wingspan and a 9 ft (3 m) longer fuselage. It was powered by two Napier Lion engines and flew for the first time on 24 November 1922.[2]


Operational history

The first squadron of Virginia Mark Is was formed in 1924. Despite mediocre performance, the aircraft served frontline units until 1938, when it was replaced by the newer Wellingtons, Hampdens and Whitleys. Designs such as the Fairey Hendon and Handley Page Heyford both supplemented and replaced the Virginia.

The final almost all-metal Virginia Mark X was the most numerous RAF bomber until the Heyford in 1934. After its technical obsolescence as a bomber, it was used for photography and for parachute training, with jump platforms installed behind the engine nacelles. On 26 June 1940, a committee discussing the need for airborne cannon for use against invading tanks suggested equipping Virginias with the equally antiquated COW 37 mm gun. This was not acted on.

In the 1930s, the Virginias were used in some of the first tests of inflight refueling, although they were never used outside of tests. The Virginia was developed in parallel with the Vickers Victoria freighter and the two aircraft had much in common, sharing the same wing design. The Virginias were highly accident prone, with 81 losses. Despite their obsolescence, Virginias continued to soldier on in support roles with the Parachute Test Flight at Henlow until December 1941.[3]

Accidents and incidents

  • 7 April 1925 – Virginia J7439 (Mk VIII, later rebuilt as Mk X): While operating with No. 9 Squadron RAF, the aircraft encountered thick fog over the Thames Estuary and was ditched in the sea off Birchington, Kent. The captain and one crew member were rescued with injuries, while the second pilot and another crewman were reported missing, believed drowned. The wreckage was recovered and rebuilt at Vickers Brooklands as the prototype Virginia Mk X, first flown in May 1927.[5]
  • 23 August 1926 – Virginia J7418 (Mk VI): A No. 58 Squadron RAF aircraft crashed at RAF Worthy Down after entering a spin while being flown solo by the pilot. The aircraft was destroyed and the pilot was killed.[6]
  • 21 March 1927 – Virginia J7425 (Mk VII): A No. 9 Squadron RAF aircraft force-landed in the Thames Estuary off Sheerness, Kent, after both engines stopped when two main fuel cocks were turned off. All four crew survived and were rescued six hours later by the trawler Pickmere, which towed the floating wreck to Sheerness. The aircraft was written off.[7]
  • 16 April 1927 – Virginia J7714 (Mk VI): A No. 9 Squadron RAF aircraft collided with the wing of a stationary Airco DH.9A during take-off from RAF Eastchurch, Isle of Sheppey. It briefly became airborne to about 100 ft (30 m) before crashing and catching fire. All four crew were killed. J7714 was the last Virginia Mk VI operated by No. IX Squadron.[8]
  • 16 June 1927 – Virginia J7437: A Virginia made a forced landing between Shipbourne and Plaxtol, Kent, in the early hours of the morning due to engine trouble. The incident was reported as a precautionary landing following mechanical failure.[9]
  • 19 August 1927 – Virginia J7418 (No. 58 Squadron): The aircraft was wrecked in a forced landing at Broadbridge Heath, near Horsham, West Sussex, after the port engine failed. One crewman was killed and three survived. The engine failure was attributed to a broken connecting rod that disrupted the oil supply.[10]
