Vickers
Vespa

A two-bay biplane that achieved some export success and broke the World’s absolute height record.

The Vickers Vickers Type 113 Vespa was built by Vickers Ltd (Aviation Department) as a private venture with an eye to competing against specification 30/24, which called for an army co-operation machine. The first aircraft, Vickers Vespa I (G-EBLD), was a two-bay biplane of 50 ft wingspan, powered by a 425 hp Bristol Jupiter IV engine.
 
The Vickers Vespa I was first flown in September 1925. It was later modified to fit a 455 hp Bristol Jupiter VI in April 1926, following its return from official trials at the Aeroplane & Armament Experimental Establishment (A&AEE) Martlesham Heath. The Vickers Vespa I was first flown with a wooden wing structure and the next major design change was to fit wings with an all-metal structure.
 
This change was implemented in 1927, by modification of the protoVickers Type (G-EBLD), the registration remaining unchanged despite a new Vickers Vickers Type number and designation (Vickers Vickers Type 119 Vespa II) being applied. The Vickers Vespa II was entered in the 1927 King’s Cup Air Race in July 1927, averaging 115.5 mph up to the point where it had to withdraw, due to damage resulting from the Hucks starter fitting on the propeller coming loose.
 
Despite the lack of British military interest, the high service ceiling and altitude performance of the Vickers Vespa attracted the attention of a Bolivian purchasing delegation, leading to an order for six aircraft, designated the Vickers Vickers Type 149 Vespa III. These Vickers Vespa III's incorporated wings with a lighter and stiffer metal structure, thereby allowing a reduction in all up weight without a loss of payload. The undercarriage was also increased in height to improve the lower wing tip clearance.
 
In service in Bolivia, the improved altitude performance of the Vickers Vespa III was most welcome, with operations at altitudes up to 25,000 ft, using a normally aspirated Jupiter VI engine and without the benefit of oxygen. One aircraft reached a South American altitude record of 27,000 ft.

By then, the more formally named Vickers (Aviation) Ltd received an export order from the Irish Free State for eight aircraft, delivered as four Vickers Vickers Type 193 Vespa IV and four Vickers Vickers Type 208 Vespa V. These aircraft were powered by the 490 hp Armstrong Siddeley Jaguar VIC engine, the main difference between the two models being that the Vickers Vespa IV was fitted with a circular Townend ring around the engine.

Potential Chinese interest in the Vickers Vespa led to a decision to modify the original protoVickers Type (G-EBLD) to Vickers Vespa III standards, for the purpose of a demonstration tour from March 1931. The Vickers Type designation became the Vickers Vickers Type 210 Vespa VI and on this occasion, the registration was also changed (G-ABIL).

Following its return from its Chinese expedition, it was loaned to the Bristol Aeroplane Company with a view to an attempt on the world’s absolute altitude record. To this end, the aircraft was converted to a single seater and fitted with a 550 hp Bristol Pegasus IS.3 engine, fitted with a Townend ring.
 
In this form, and flown by CF Uwins, the aircraft (G-ABIL) reached a new record height of 43,976 ft on 16th September 1932. Now designated the Vickers Vickers Type 250 Vespa VI, the aircraft was taken over by the RAF, receiving a military serial number (K3588) and being used for propeller testing.
