Vickers Vildebeest Mk. III
Vickers Vildebeest Mk. IV Perseus Engine Version
Vickers Vincent
In the period between the two world wars, the RAF operated a
number of types of large single-engine biplanes, the Vickers Vildebeest being a
typical example. Its origins went back to 1926, when Vickers tendered to
Specification 24/25 for a torpedo-bomber to replace the Hawker Horsley. An Air
Ministry order for a prototype was received, and as the Vickers Type 132 it
flew from the company’s Brooklands Airfield, Weybridge, in April 1928, powered
by a 460-hp (343-kW) Bristol Jupiter VIII geared engine, later going to the
Aircraft and Armament Experimental Establishment at Martlesham Heath for
competitive trials with the Blackburn Beagle. Following these it was tested on
floats at the Marine Aircraft Experimental Establishment at Felixstowe.
Initial problems were concerned mainly with engine cooling,
and several versions of the Jupiter were tried without encouraging results.
Eventually, a second prototype was built as a private venture: this flew from
Brooklands in August 1930, powered by a geared Armstrong Siddeley Panther IIA
engine, but its performance was, if anything, worse.
Finally, the 660-hp (492-kW) Bristol Pegasus became the
standard Vildebeest powerplant, and with successful trials at last behind it
the type was accepted, nine aircraft being ordered to revised Specification
22/31. In 1932 Vickers signed a licensing agreement under which 25 Vildebeests,
with 600-hp (447-kW) Hispano Suiza 12Lbr engines, were built by CASA at Madrid
for service with the Spanish navy.
Deliveries to the RAF began in 1933, when No. 100 Squadron
at Donibristle received a batch of the first production Vildebeests, having had
one aircraft for familiarisation for several months. The squadron moved
subsequently to Singapore, and the type was to remain in service in the Far
East well into World War II.
Further contracts followed, and improved marks of Vildebeest
entered service. The Mk II, ordered in December 1933, was fitted with a 635-hp
(474-kW Pegasus IIM3 engine, but when 30 had been built a modification was
requested by the Air Ministry to a new specification, 15/34. A third crew
member position was required and the rear cockpit was redesigned. In this form
the aircraft was designated Mk III. Production aircraft were delivered to Nos.
22 and 36 Squadrons during 1935-6 and 12 were ordered for the Royal New Zealand
Air Force, another 15 being diverted later from the RAF order. The RNZAF
Vildebeests had folding wings.
The final production version was the Mk IV, 56 of which were
ordered in December 1936 with 825-hp (615-kW) Bristol Perseus VIII sleeve-valve
engines, the first such engine to enter RAF service. Performance was
considerably improved, and the first Vildebeest Mk IVs were delivered to No. 42
Squadron in 1937, remaining in service until replaced by Bristol Beauforts in
1940. The last Vildebeest IV was delivered in November 1937, and total
production of the Mks I to IV amounted to 194.
At the outbreak of World War II about 100 Vildebeests were
still in service, and the Singapore-based aircraft with Nos. 36 and 100
Squadrons operated against the Japanese until Singapore fell in 1942.

Vickers Vincent
A need to replace the Westland Wapiti and Fairey IIIF
general-purpose biplanes led the Air Ministry to order a modified version of
the Vickers Vildebeest to Specification 21/33. A tour of RAF stations in the
Middle East and Africa in 1932-3 by a converted Vildebeest had shown that the
type would be a suitable replacement, and 51 were ordered on 8 December 1933
under the name Vincent. In place of the torpedo, the Vincent carried a
long-range fuel tank beneath the fuselage, and other special equipment included
message pick-up gear and pyrotechnics.
The first production Vincent, converted from a Vildebeest Mk
II to the revised Specification 16/34, was seen for the first time in public at
the 1935 RAF Display at Hendon. However, initial deliveries of production
aircraft had been made to No. 8 Squadron at Aden in late 1934, eventually
replacing the Fairey IIIFs then in service with Bristol Blenheims.
Total Vincent production was 171, and a number of others
were converted from Vildebeests to bring the total to almost 200. More than 80
were still in service at the beginning of World War II, and Vincents saw action
with No. 244 Squadron in Iraq in 1941, being replaced eventually by Bristol
Blenheims.

To Malaya
The Vildebeest first entered service with 100 Squadron at
Donibristle in November 1932. The unit was shipped to Singapore as part of the
beefing up of the naval base’s defences and was ready for duty at Seletar in
January 1934. The resident 36 Squadron retired its Horsleys in July 1935 and
converted to Vildebeests.
SEALED ORDERS
At 11:15 hours local on September 3, 1939, Britain declared
war on Germany. A day later, 6,800 miles (10,840km) to the east, the
seriousness of the world situation was felt at Seletar. A 100 Squadron
Association pamphlet relates that a film being shown in the station cinema was
interrupted. A notice flashed on the screen ordering all personnel of `A’ and
`B’ Flights of 36 Squadron and `B’ Flight of 100 Squadron to report to their
hangars immediately. There is a note that those that got up and left did not
get a refund!
Three Vildebeests of 100 Squadron were being prepared: K6384
(Flt Lt Smith, the flight leader), K6385 (Plt Off Richardson) and K6379 (Plt
Off Davis). Each aircraft was to carry two more crew members, a mixture of
wireless operator/gunners, fitters and armourers.
The commanding officer, Sqn Ldr R N McKern, set a sombre
tone, explaining that the unit was on a war footing and wished the men good
luck. The document takes up the story: “The three aircraft became airborne
at 09:45 hours local on September 5, 1939, just 39 hours an 10 minutes after
war was declared…
“As soon as the aerodrome was cleared, the pilots
opened their sealed envelopes and then told their crews that their destination
was Kepala Batas, north of Alor Star. [On the western coast of the Malay
Peninsula, 20 miles from the border with Siam, today’s Thailand.] The aircraft
set course for the northwest tip of Malaya and a loose formation was adopted.
The flight took 4 hours 30 minutes and proved to be uneventful.”
After ‘tiffin’ at the government rest house at Kepala Batas,
around 16:00, the nine men: “All got busy unpacking and `hunking’ around
bombs, 112- and 250-pounders, both general purpose and armour piercing, which
were stored there for emergency use. There were no trolleys nor any means of
moving these bombs – only brute strength and sweat!
“Each bomb was in its own wooden crate which was
screwed, not nailed, together. The bombs were manhandled to rows some distance
from the aircraft and covered with tarpaulin sheets. They were completely safe –
they hoped – and the fuzes were locked up well away from both the bombs and the
machines, in the rest house. There were no torpedoes.
“Fifteen days later those nine men, with their
Vildebeests, saw Seletar again.” The men of 36 and 100 Squadrons were
thrown into the front line from December 1941 fighting rear guard action before
Singapore fell to the Japanese.
The three aircraft that deployed to Kepala Batas on September 5, 1939 illustrate the fate of the Vildebeest force. While attacking a Japanese ship during the intense naval engagement off Endau up the eastern Malayan coast from Singapore, on January 26, 1942, K6379 was seen to dive into the sea. It was one of 13 of the torpedo-bombers lost that day.
Further up the eastern coast on February 9, the Vildebeests
were flying from a strip at Kuantan and K6385 was destroyed on the ground by
Japanese aircraft. By late February 1942 surviving British forces had regrouped
in central Java, including two serviceable Vildebeests. On the 29th K6384
failed to return from a recce and it is believed to have been shot down near
Semerang, east of Jakarta. With that the big biplane’s last stand was over
Disaster at Endau
From Brian Cull’s Hurricanes Over Singapore: RAF, RNZAF and
NEI Fighters in Action Against the Japanese Over the Island and the Netherlands
East Indies, 1942.
64th Sentai operated from Ipoh in January 1942, the 59th
Sentai from Kahang.
The Hayabusa fighters of the 64th Sentai were among the very
first fighters to saw action in the Pacific. The Ki-43s Hayabusa of Kato Air
Group escorted Yamashita’s troop transports en route to invade Malaya and some
were lost when they were unable to return to Pho Quok island a day before the
war broke out. They flew air cover within the maximum operational range which was
quite a feat in those days.
Hiroshi Onozaki was among the ‘Nate’ pilots who flew air
cover over the Takumi’s invasion force at Kota Bharu beach on the first day of
the war.
Even today in Japan his memory is kept alive by the popular
song ‘Kato Hayabusa Sentoki Tai’ (Fighter Air Group Kato).
Cull states that Yasuhiko Kuroe was the only pilot of the
47th Independent at the “disaster at Endau”, the disastrous RAF
attack on the 26th January 1942. Pilots
of the 1st and 11th Sentais also took part.
The Ki.44 entered combat for the first time on January 1,
1942, when a flight of three Ki.44s led by Captain Yasuhiko Kuroe attacked
three Buffalos of 21 and 453 Squadrons in the vicinity of Johore Baru, just
north of Singapore, with Captain Kuroe scoring that first kill.
The Ki-44 was quite fast compared with other Japanese
fighters and most of the attacking British planes at Endau were very slow such
as the Vildebeeste biplanes.
1st and 11th Sentai had Nates but no mention made of those
units’ kills.
Japanese losses were two Nates,1st Sentai:
Lt Mizotani shot down but baled out safely
Lt Toshiro Kuboya, shot down and seriously wounded, died
three weeks later.
RAF attacking force is given as 21 Vildebeest,3 Albacores,9
RAAF Hudsons,18 Buffaloes and 9 Hurricanes as escorts. The Japanese also claim
a Dutch Catalina was encountered. A ABDA force of US B-17s from Java, via
Sumatra, was requested as well but “arrived too late”.
RAF losses in the two raids are given as 10 Vildebeest,2 Albacores,2 Hudsons and 1 Hurricane. Two more Vildebeests were written off, too damaged. 39 aircrew were initially lost–28 killed, 2 taken prisoner, 9 who eventually made it back to Singapore.
