Harland and Wolff - Shipbuilding and Engineering Works

Assembly-line production of aircraft in Ulster commenced in 1917, when the company were awarded a series of contracts for a combined total of 1,000 aircraft for the Royal Flying Corps and Royal Naval Air service.  In response, during the period 1917-20, the company produced at least 600 aeroplanes, mostly the Airco DH.6 and Avro 504 types plus a comparatively small number of Handley-Page V1500 bombers.

To facilitate the test-flying of the V1500s, an airfield was constructed at Aldergrove. Whereas Harland and Wolff stopped building aircraft in 1920, the experience gained was a factor which led to the creation of Short & Harland in 1936, the result of an amalgamation between the world’s oldest aircraft manufacturers Short Brothers (Rochester & Bedford) Ltd and Harland & Wolff. In 1947, following a decision by Short Brothers to cease their design and manufacturing work in England, Short & Harland took over the company which then became Short Brothers & Harland Ltd, then Short Brothers Ltd and then Short Brothers plc until taken over by Bombardier Inc in 1989.

Production line construction of the Avro 504

The Airco DH.6 was a British military trainer biplane used by the Royal Flying Corps during the First World War. Known by various nicknames, including the "Skyhook", the trainer became a widely used light civil aircraft in the postwar era.

Handley-Page V1500
Owing to pressure of work at Handley Page's Cricklewood factory, and to ensure security, the first prototype Handley-Page V1500 was constructed by Harland and Wolff at Belfast, being assembled at Cricklewood and first flying on 22 May 1918.
