Vickers Warwick, Wellesley, Vincent and Type 253

The Vickers Vincent was a version of the Vildebeest torpedo bomber modified to operate as a general purpose aeroplane, a role that combined army-cooperation, ground attack and light bombing functions and was designed for Imperial policing
The Vickers Type 253 general purpose biplane was the first aircraft to use the geodetic construction method devised by Barnes Wallis, and made famous on the Wellington bomber.
The Vickers Wellesley was the first aircraft built entirely using Barnes Wallis’s geodesic construction method to enter service, and is best known for establishing a new world distance record in 1938.
The Vickers Warwick was one of many examples of promising aircraft whose development was delayed by the choice of engines. It was originally designed as a twin-engined heavy bomber, and like the Avro Manchester was to use the Rolls Royce Vulture.
