Source-derived summary

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. 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.

Editorial summary

This brief starts where responsible research should: with the source description of “Sikorsky XP2S” as 1932 prototype flying boat model by Sikorsky. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA dependable orientation record for establishing vocabulary, names and a first evidence trail. The current lead gives the account dated anchors—1930, 1932, 1340, 1919—that can be checked directly. The selected authority fields contribute no independent date. The account is most persuasive where Sikorsky, XP2S and prototype can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as 1932 prototype flying boat model by Sikorsky. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 28, 2025. The linked authority identifier is Q48800230. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1930, 1932, 1340 and 1919.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
