The Sikorsky XP2S was an American biplane patrol flying boat developed for the United States Navy during the early 1930s.

Design and development

After selling a small quantity of PS / RS patrol / transport amphibians to the Navy, Sikorsky (then a division of United Aircraft Corporation) endeavoured to interest the service in a patrol flying boat. Having received a development contract in mid-1930, Sikorsky delivered a complete aircraft for testing in June 1932.^[1] The XP2S-1, as the prototype was designated, was a two-bay, equal-span biplane of mixed construction. Its two R-1340 Wasp radial engines were mounted in a single nacelle in a tandem configuration.

Its overall performance did not exceed that of other biplane patrol boats of the era, and after approximately one year of official trials the Navy cancelled the project.^[1]
