The Curtiss HS-2L was a single-engined patrol flying boat built for the US Navy during the First World War. Large numbers were built from 1917 to 1919, with the type being used to carry out anti-submarine patrols from bases in France from June 1918. It remained in use with the US Navy until 1928, and was also widely used as a civil passenger and utility aircraft. From August 1918, in order to compensate for Canada's lack of patrol aircraft, US Navy HS-2Ls operated from two bases in Nova Scotia. Twelve HS-2Ls were donated to the Canadian Air Board at the end of the war, following the closure of Naval Air Station Halifax. The RCAF acquired 30 HS-2Ls. Many were used in Canada as the first bush plane. One was recovered from a lake in Quebec and is now on display in the Canada Aviation and Space Museum, Ottawa, Ontario.
Three HS-2Ls were modified in Canada by Canadian Vickers with different wings (Clark Y section), and designated HS-3L. Harold A Skaarup Web Page
