The Valentia (within the company known as the Type 264) was a British biplane cargo aircraft built by Vickers for the Royal Air Force. The majority built were conversions of the early Vickers Victoria.While the Napier Lion-powered Victoria served successfully with the RAF as a bomber transport, by 1932, the Lion engine was becoming obsolete and it was clear that it could use more power. It was therefore decided to re-engine the aircraft with more powerful Bristol Pegasus engines. It was decided to carry out a two-stage upgrade, with the first, which was designated the Victoria Mk VI, or Configuration I, retaining the airframe of the Victoria, and therefore having a limited maximum weight, and a version with a strengthened airframe capable of taking full advantage of the greater power of the Pegasus engine. This was known as Configuration 2 and was designated the Vickers Valentia. It flew for the first time in 1934.
