The Sopwith 1½ Strutter was an innovative multi-role airplane, designed to answer the request of the British Admiralty for a two-seat bomber for the Western Front. Its nickname comes from the odd shape of the inboard struts, which attached to the fuselage rather than to the lower wing. It was the first British airplane to use a synchronized machine-gun for the pilot – able to fire through the rotating propeller – and the first two-seater with a “puller” engine. It served with both British air services and was also widely used by French aviation.
The Sopwith 1½ Strutter Comic was derived from the two-seater Sopwith 1½ Strutter. The Comic was modified to become a single-seat fighter, used by British Home Defense to defend the British Isles from German bombing raids.
