On February 9, 1916, Herbert Smith's small 80 hp single seat "Fighting Scout" Passed its acceptance tests and was cleared for production by the Sopwith Aviation Co. LTD. The Sopwith Pup sow combat on every major front of World War I and perfomed almost every duty asked of a combat aircraft. Along with the Pup's combat success, it was also a pioneering aircraft of Naval shipboard aviation. The Pup was one of the first aircraft to successfully take off and land on a ship at sea, one of the first aircraft to experiment with "arresting gear" for shipboard landings, and also one of the first aircraft to actually engage in aerial combat after being launched from a ship at sea. However, you should realize the real key to the Pup's success was its outstanding flight characteristics.
