This article is about the post World War II airliner. For the single-engined amphibian Vickers Viking of 1918, see
Vickers Viking.
The Vickers VC.1 Viking was a British twin-engine short-range airliner derived from the Vickers Wellington bomber and built by Vickers Armstrongs Limited at Brooklands near Weybridge in Surrey. In the aftermath of the war, the Viking was an important airliner with British airlines pending the development of turboprop aircraft like the Viscount. An experimental airframe was fitted with Rolls-Royce Nene turbojets and first flown in 1948 as the world's first pure jet transport aircraft.
[edit] Design and development
The Ministry of Aircraft Production ordered three prototype Wellington Transport Aircraft to Air Ministry Specification 17/44 from Vickers-Armstrong Limited. The specification was for a peacetime requirement for a medium-short haul passenger aircraft. To speed development the aircraft used the wing and undercarriage design from the Wellington but the fuselage was new. Although the original contract referred to Wellington Transport Aircraft, on completion, the name Viking was chosen.
The prototype (designated the Type 491 and registered G-AGOK) first flew at Wisley Aerodrome on 22 June 1945.[1] Following successful trials of the three prototypes the British Overseas Airways Corporation (BOAC) ordered 19 aircraft. The first BOAC aircraft flew on 23 March 1946. The prototypes were then used for trials with the Royal Air Force which lead to orders for military versions (the Viking C2 (12 ordered as freighter/transports) and modified Valetta C1).
The jet-powered Vickers
Nene Viking
G-AJPH The initial 19 production aircraft (later designated the Viking 1A) carried 21 passengers, they had metal fuselages and fabric-clad geodetic wings and tail units. Following feedback from customers, the next 14 examples, known as the Viking 1, featured stressed-metal wings and tail units. The next variant, the Viking 1B, was 28 in (71 cm) longer, carrying 24 passengers with up-rated Bristol Hercules piston engines, achieved a production run of 115. One of this batch was changed during production to be fitted with two Rolls-Royce Nene turbojet engines and upon its first flight on 6 April 1948 became the world's first entirely jet-powered airliner (albeit only a prototype). The Type 618 Nene-Viking flew Heathrow-Paris on the anniversary of Blériot's crossing of the Channel, 1948 taking only 34 minutes (c.210 mi/340 km, 370.6 mph/596.4 km/h). Some six years later, it was converted to a piston engined Viking.[2]
Production finished in 1948, including 16 for the RAF and the King's Flight, but in 1952 BEA adapted some to a 38-passenger layout, taking the maximum payload up from 5,500-7,200 lb (2,500-3,300 kg). All Vikings featured a tailwheel undercarriage.
The 158th Viking became the prototype of the military Valetta, of which 261 were sold. When production of this strengthened but externally-similar type ended in 1951, a flying classroom version with tricycle undercarriage was already being delivered to the Royal Air Force (RAF), called the Varsity.[3]All but one of those entered RAF service, the other example going to the Swedish Air Force. The production of 161 Varsitys kept the Hurn works busy until January 1954, and they enjoyed a long service life. Examples are preserved at Brooklands Museum, the Imperial War Museum Duxford and the Newark Air Museum.
[edit] Operational history
BEA Vickers Viking 1B G-AHPO "Venturer" at Manchester in 1952
The first Viking was flown from Vickers' flight test airfield at Wisley, Surrey, by chief test pilot Joseph "Mutt" Summers on 22 June 1945 and the third aircraft built was delivered to BOAC at Hurn near Bournemouth on 20 April 1946. Upon the delivery of nine examples to BOAC for development flying, including the two remaining prototypes, British European Airways (BEA) was established on 1 August 1946 to operate airliners within Europe and these first VC.1 Vikings were transferred to the new airline.[4]
After a trial flight from Northolt to Oslo on 20 August 1946 by the newly formed BEA, the first regular Viking scheduled service commenced between Northolt and Copenhagen on 1 September 1946.
In all 163 Vikings were built. The initials "VC" stood for Vickers Civil, echoing the "DC" precedent set by the Douglas Aircraft Company of the USA, builders of the DC-1, DC-2 and DC-3 Douglas Dakota, the latter also bought by BEA and of a similar configuration to the Viking. Vickers soon ceased to use the 'VC' letters, instead using type numbers in the 49x and 600 series, which indicated the specific customer airline.

Blackbushe Airport, Hants, in April 1955
BEA operated their large fleet of Vikings on many European and UK trunk routes for eight years. From 1951, the remaining fleet was modified with 36, instead of 27 seats, and named the "Admiral Class". BEA operated the Viking until late 1954, when the last was displaced by the more modern and pressurised Airspeed Ambassador and Vickers Viscount.
BEA sold their Vikings to several UK independent airlines for use on their growing scheduled and charter route networks. Some were sold to other European operators. An ex-BEA Viking 1B was fitted out as a VIP aircraft for the Arab Legion Air Force, mainly for the use of the King of Jordan.[5] Most Vikings had been retired from service by the mid 1960s and the sole surviving example in the UK is owned by Brooklands Museum where it is under long term restoration.
