The Hanriot HD.2 was a biplane floatplane fighter aircraft produced in France during the First World War which was used after the war for testing the use of aircraft from warships. DevelopmentThe design was based on that of the HD.1, but was a purpose-built floatplane. It had larger tail surfaces and a shorter wingspan with greater area. Like its predecessor, though, it was a conventional single-bay biplane with staggered wings of unequal span. The prototype had a twin pontoon undercarriage, with a small third pontoon under the tail. The third pontoon was later discarded on production machines, though. Operational historyThe HD.2 was developed specifically as an interceptor to defend flying boat bases, but soon was used as an escort fighter to protect French reconnaissance flying boats. The United States Navy also bought 10 examples with wheeled undercarriages, designated HD.2C. Both the French and United States navies used these aircraft in early experiments in launching fighters from warships. The United States Navy replicated the French trials where a HD.1 had been launched from a platform built atop one of the turrets of the battleship Paris and built a similar platform on the USS Mississippi to launch a HD.2 from. The French Navy converted some of their HD.2s to wheeled configuration and used them for trials on the new aircraft carrier Béarn. A final experiment in launching a HD.2 from a ship was carried out in 1924 with two new-built examples designated H.29. An unorthodox launching system was developed where the aircraft were equipped with three small pulley-wheels, one on each tip of the upper wing, and one at the tip of the tail fin. These ran along metal rails that had been attached to project horizontally from the mast of the battleship Lorraine. This did not work as hoped, succeeding only in depositing the aircraft into the water below. Further trials were discontinued. Variants
