The Beardmore W.B.1 was a British single-engine bomber biplane of World War I developed by Beardmore.[1]

Development and design[edit]

In 1916, G. Tilghman Richards, the newly appointed chief designer of the aviation department of the Scottish shipbuilder William Beardmore, designed his first aircraft for Beardmore, the W.B.1. This was to be a single engined bomber for the Royal Naval Air Service (RNAS), which was intended to carry out long gliding attacks to achieve surprise. It was a three-bay biplane with long span high aspect ratio wings, which were highly staggered.[2] It was powered by a 230 hp (172 kW) BHP engine and first flew in early 1917.[3]

The W.B.1 was delivered to the RNAS at Cranwell for evaluation on 8 June 1917.[4] By this time however, the larger and more capable Handley Page O/100 was in production and the W.B.1 was rejected by the RNAS.[3]
