Vickers Type 264 Valentia
:''For the flying boat, see Vickers Valentia''
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 earlier Vickers Victoria.
==Design and development==
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.
Orders were placed for the 28 new build Valentias to Specification 30/34, with a further 54 being converted from Victorias (Type 278 within the company), with production continuing until 1936.〔
