Vickers
Virginia

A long-lived and largely unsung heavy bomber that also gave rise to the Victoria and Valentia military transport aircraft.

The Vickers Virginia was first flown in 1922 and after progressive development, it remained in RAF front-line service until 1938.
 
The Virginia was designed by Vickers Aviation Ltd Chief Designer RJ 'Rex' Pierson as a conventional twin-engine biplane of wooden structure with folding wings. The first prototype (J6856) was powered by two 468 hp Napier Lion IAZ engines and was flown for the first time at Brooklands  on 22nd November 1922.
 
A second prototype (J6857) was also flown there in July 1923.
 
As initially flown, the prototypes featured wings with no sweep or stagger. The top wing had no dihedral but the lower wings had dihedral outboard of the engines. During its first flight, the prototype had a significant control problem and the rudders proved largely ineffective. These were duly increased in chord, with the unwanted side effect of extremely heavy control loads.
 
Flight performance was also very disappointing, possibly due to the drag of the engine installation, with its frontal radiators and large flat-sided nacelles. The quoted maximum speed was only 97 mph.
 
The internal bomb load was 9 x 112 lb bombs and as initially flown, there was no provision for defensive armament. Consequently, Vickers were asked to provide gunners’ cockpits and they modified the first prototype (J6856), in June 1923. Gun positions were installed fore and aft, on each upper wing, in 'chordwise' nacelles known as ‘fighting tops’. A gunnery position was also provided in the extreme nose.

The second prototype (J6857) adopted a revised engine installation, with its Lion II engines raised above the wing in a circular nacelle supported by struts. Cooling was provided by a pair of semi-circular radiators below the wing leading edge and between the undercarriage legs. This became the standard installation for the later production machines. The nose was also lengthened to allow the nose-gunner to lie prone to act as a bomb-aimer if required. A hinge was also introduced in the rear fuselage to enable the tailplane incidence to be adjusted in flight.
 
A further iteration of the ‘fighting tops’ scheme saw one aircraft (J6856) modified to have a gunner's position on the trailing edge of each upper wing, with a ‘crawl-way’ with handrails to allow the gunners to ascend or descend via a circular aperture in the wing centre-section.

Limited production began with six vickers Virginia Mk IIIs (J6992-3 and J7129-32) with the first two being used for Service trials at Bircham Newton from the spring of 1924. Although the flight performance was disappointing, the aircraft were sturdy and reliable, and it was decided that further production for operational service was justified.

Next to fly were a pair of interim vickers Virginia Mk IVs which had the provision for the external carriage of two 230 lb bombs in addition to the internal bomb load. These aircraft were also equipped for night flying.
 
The first Vickers Virginia Mk IV had been flown with a third central rudder and this was adopted as standard for the Vickers Virginia Mk V.
 
22 aircraft of this type were ordered, serving with 58 Sqn and 9 Sqn, RAF.
 
The next production model was the vickers Virginia Mark VI, 25 of which were built. On these aircraft, the dihedral geometry was changed with both upper and lower wings having 2.5 degrees dihedral, which simplified the wing folding operation. The Vickers Virginia Mk VI served with 7, 9 and 58 Sqn, so that all three were now flying the same mark of the type.

With increased service use, it soon became apparent that the Vickers Virginia’s control characteristics were problematic. Its heavy rudder and aileron loads combined with inadequate longitudinal stability made it physically demanding, and tiring to fly, particularly in turbulent conditions. These challenges were addressed by the Vickers Virginia Mk VII, which introduced six degrees of sweepback on the outer wing panels with a longer rear fuselage, and the use of Frise ailerons to reduce the lateral control loads.

Possibly spurred on by the poor handling of the early marks, the Vickers Virginia became the subject of autopilot research at the Royal Aircraft Establishment. By the time that the final version (Mk X) was in service, a reliable and effective three-channel autopilot was available.
 
The Vickers Virginia Mark VIII was a one-off experimental reconfiguration of the original prototype (J6586) to be powered by two 650 hp Condor III engines. It was also fitted with a dihedral tailplane although no further development was undertaken thereafter. A number of other engines were test flown in various Virginia aircraft, including the Jupiter, Pegasus and Armstrong Siddeley Jaguar engines.
 
The Vickers Virginia Mk IX saw the introduction of a rear defensive gun position in the very tail of the aircraft.
 
The prototype for the Vickers Virginia Mk IX (J7131) had been originally built as a Mk III. It was then converted to a Vickers Virginia Mk VII before finally becoming the first Mk IX. The tailplanes were increased in span and area, whilst the rudders were set further apart.
 
Additionally, the nose was increased in length by some three feet to balance out the weight of the rear-mounted gun position.

The last major development of the Vickers Virginia was a change to all-metal construction, resulting in the final Vickers Virginia Mk X. Fifty new-build aircraft were ordered and all of the surviving earlier marks (a total of 53 aircraft) were converted / remanufactured to the Vickers Virginia Mk X standard.
 
These aircraft re-equipped the existing Vickers Virginia squadrons by 1931, with early aircraft being powered by the Lion VB engine, whilst later aircraft received 580 hp Lion XI engines.

Some of the last of the type to remain in service were used by the Parachute Testing Unit at RAF Henlow, although a number of Vickers Virginia aircraft remained in use on non-operational tasks as late as 1941.
