The Vickers-Armstrong Wellington, a two-engined medium bomber, was by results the best of the British mediums. The plane was widely known as the Wimpy in honor of the popular J Wellington Wimpy character in the Popeye comic strips and movie cartoons.

Built with Wallis' "geodesic" construction methods — doped linen over wood battens over aluminum beams, called by detractors the "basket weave" method — the Wellington was light for its size, giving it better load-over-distance capacity than its rivals in the British mediums camp. As such, it carried a good deal of the bombing load against the Continent until the heavies came on line.

Also built with the "geodesic" construction methods and described by Jane's as a development of the Wellington, the Warwick saw many uses but was primarily a transport.
