Sikorsky Aircraft

The Sikorsky VS-44 is a large four-engined flying boat built in the United States in the early 1940s by Sikorsky Aircraft. Based on the XPBS-1 patrol bomber, the VS-44 was designed primarily for the transatlantic passenger market, with a capacity of 40+ passengers. One XPBS-1 patrol bomber prototype was built, along with three airliners named Excalibur, Excambian, and Exeter.
