The Vickers Vildebeest and the similar Vickers Vincent were two very large two- to three-seat single-engined British biplanes designed and built by Vickers and used as light bombers, torpedo bombers and in army cooperation roles.[Note 1] First flown in 1928, it remained in service at the start of the Second World War, with the last Vildebeests flying against Japanese forces over Singapore and Java in 1942.

Design and development

[edit]

Vildebeest

[edit]

Designed against Air Ministry Specification 24/25 for the Royal Air Force (RAF), for a land-based torpedo bomber to replace the Hawker Horsley, the prototype Vildebeest, an all-metal fuselage aircraft with single-bay unstaggered fabric-covered wings and tail, was first flown in April 1928 as the Vickers Type 132, powered by a Bristol Jupiter VIII radial engine.[2]

After initial evaluation, the Vildebeest was shortlisted for comparison with the Blackburn Beagle and Handley Page Hare. As the Jupiter VIII was prone to vibration, a second prototype, the Vickers Type 204[3] was fitted with an Armstrong Siddeley Panther IIA engine and after further testing, the Vickers design was confirmed as the winner of the contest[4] but engine problems persisted until the type was tested with a new version of the Jupiter, which later became known as the Bristol Pegasus.[5] An initial production order was placed in 1931 for nine aircraft, with the first production aircraft flying in September 1932.[5]

Further production ensued, with an improved version fitted with a 635 hp (474 kW) Pegasus IIM3 entering service but after only 30 examples had been produced the Air Ministry requested a modification (Specification 15/34) which added a third crew position, thus creating the Vildebeest Mk III, of which 150 examples being built for the RAF.[6]

The Mark IV introduced the much more powerful 825 hp (615 kW) Bristol Perseus sleeve valve radial engine enclosed in a NACA cowling which significantly improved performance, increasing maximum speed to 156 mph (251 km/h) and rate of climb to 840 ft/min (4.3 m/s).[7] In this version, the Perseus had overheating problems and was deemed unsuitable for tropical service[8] with production limited to 18 aircraft, all of which served with the home based squadrons.[9]

Vincent

[edit]
Vickers Vincent

In 1931, Vickers designed as a private venture a General Purpose version of the Vildebeest to replace the RAF's Westland Wapitis and Fairey IIIFs, supporting the Army in the Middle East. Successful trials were conducted in the Middle East, Sudan and East Africa with a converted Vildebeest I in the General Purpose role during 1932–1933, and Specification 16/34 was drawn up based on the three man Vildebeest, which was named the Vickers Vincent: differences from the Vildebeest were minimal (the first production Vincent was, converted from a Vildebeest MkII), principally removal of torpedo equipment, provision for an auxiliary fuel tank, message-pick-up and pyrotechnic signalling gear.

Powered by a 660 hp (490 kW) Bristol Pegasus IIM3[10] the Vincent was unveiled to the general public for the first time at the 1935 RAF flying display at Hendon, but deliveries had already been made to No. 8 Squadron at Aden in late 1934.

Between 1934 and 1936, 197 Vincents were built for or converted from Vildebeests for the RAF.[11]

Operational history

[edit]

United Kingdom

[edit]
Vildebeest Mk II of No. 100 Squadron RAF making a torpedo drop during target practice, circa 1936.

The Vildebeest was purchased in moderately large numbers by the Royal Air Force from 1931 and used as a torpedo bomber. It entered service with No. 100 Squadron at RAF Donibristle in Scotland in October 1932, replacing the Hawker Horsley.[12] Four frontline torpedo-bomber squadrons were equipped with the Vildebeest, two at Singapore (100 Squadron, which moved from the United Kingdom in 1933 and 36 Squadron, which replaced its Horsleys in 1935), and two more in the United Kingdom.[13] The Vincent entered service with No. 84 Squadron RAF at Shaibah, Iraq in December 1934, re-equipping General Purpose squadrons throughout the Middle East and Africa.[14] By 1937, it equipped six squadrons in Iraq, Aden, Kenya, Sudan, and Egypt.[15] At the outbreak of the Second World War, 101 Vildebeests were still in service with the RAF. The two British-based squadrons flew coastal patrol and convoy escort missions until 1940 when their Vildebeests were replaced by the Bristol Beaufort.[16]

The two Singapore-based squadrons were still waiting for their Beauforts when Japan invaded Malaya in December 1941 and the obsolete biplanes had to be deployed against the Japanese attackers, making an abortive torpedo attack on a Japanese cruiser off Kota Bharu on 8 December.[9][17] The Vildebeests continued to attack the Japanese as their forces advanced down Malaya, sustaining heavy losses from Japanese fighters, particularly when no fighter cover could be provided. On 26 January 1942, the Japanese landed at Endau, 250 miles from Singapore, and 12 Vildebeests of 100 and 36 Squadrons were sent to attack the landings. Despite an escort of Brewster Buffalo and Hawker Hurricane fighters, five Vildebeests were lost. The attack was repeated later that day by eight Vildebeests of 36 Squadron and three Fairey Albacores, resulting in six more Vildebeests and two Albacores being shot down.[9][18][19]

Vildebeest Mk.IIIs of 100 Squadron refuelling at Singapore, 1942.

The surviving Vildebeests were withdrawn to Java on 31 January and attacked another Japanese landing force off Rembang, claiming eight ships sunk but sustaining further losses. The final two Vildebeests of 36 Squadron attempted to escape to Burma on 6 March but were lost over Sumatra. The last Vildebeests in RAF service, operated by 273 Squadron at Ceylon were retired in March 1942.[9][20]

While the Vincent had started to be replaced by more modern aircraft such as the Vickers Wellesley and Bristol Blenheim bombers, 84 remained in service with the RAF on the outbreak of the Second World War.[14] Vincents were used for bombing missions against Italian forces in the East African Campaign and for coastal patrols from Aden, one attacking the Italian submarine Galileo Galilei.[15] Other Vincents bombed Iraqi forces during the Anglo-Iraqi War of 1941.[21] The last frontline Vincents retired in January 1943, with the type continuing in second line service (which included pesticide spraying against locusts in Iran) until 1944.[15]

Spain

[edit]

The Vildebeest was ordered by the Spanish Republic in 1932 and licence production of 25 Vildebeest for the Spanish Republican Navy was undertaken in Spain by CASA most receiving the Hispano-Suiza HS 600 inline engine, though some other engines were also used. Around 20 survived to fight with the Spanish Republican Air Force on the Republican side of the Spanish Civil War, some equipped with floats.

A Vildebeest was the first victim of Francoist ace Joaquin Garcia-Morato.[22]

New Zealand

[edit]

12 Vildebeests were purchased by the Royal New Zealand Air Force in 1935 for coastal defence, with a further 27 acquired from RAF stocks in 1940–41.[23] In addition, 60 or 62 of these machines, (depending on source), were passed on to the RNZAF.[15][23]

New Zealand Vildebeests were also used for photo mapping. A few were used for maritime patrols against German surface raiders, and Japanese submarines, (a handful were based in Fiji in December 1941), but the main wartime role of the New Zealand aircraft was as particularly unwieldy pilot trainers, until replaced by North American Harvards in 1942.

Surviving aircraft

[edit]

A Vildebeest/Vincent composite airframe is being restored by the Air Force Museum of New Zealand at Wigram Aerodrome in Christchurch, from the substantially complete remains of Vildebeest Mark III NZ102, incorporating parts from Vildebeest NZ105 and Vincents NZ355 and 357.[23][31] A Vincent (NZ311) has nearly completed restoration to static display by the Subritzky family near Auckland, New Zealand. A Spanish Vildebeest is rumoured to have survived.
