While most Sopwith fighters used a rotary engine, the Sopwith 5F.1 Dolphin used a Hispano-Suiza vee. The upper wing sat low on a deep cockpit to give the pilot maximum visibility, with his head poking out in a cage structure splitting the upper wing. The lower wing was negatively staggered to maintain the correct center of gravity. Pilots were not keen on this arrangement, though, fearing being decapitated if the plane should flip over. Those fears were unfounded though, and the plane proved easy to fly and quite capable. The first operational trials commenced in June 1917, but it was not until the late months of 1917 that production units reached the front. Problems with the geared 200hp Hispano-Suiza plagued rapid production, just as it was slowing the R.A.F. S.E.5a.
Twin synchronized Vickers were fitted to the fuselage, and a late addition added two limited-movement Lewis guns aimed upward at a 45° angle, though the latter were frequently removed. The Dolphin performed all the normal fighter patrol and escort duties and one unit was issued Dolphins for Home Defense.
A version using the powerful 300hp Hispano-Suiza was in testing at the end of the war and was anticipated for use by both French and American units.
