The Sikorsky S-45 was a proposed double-deck transoceanic flying boat originally designed in 1938 by Sikorsky Aircraft for Pan Am. The high wing monoplane featured a single-step hull with a triple-tail and was to be powered by six Wright R-3350 Duplex-Cyclone engines which were being developed at the time. Sikorsky Aircraft is an American aircraft manufacturer Stratford, Connecticut. It was established by aviation pioneer Igor Sikorsky in 1923 and was among the first companies to manufacture helicopters for civilian and military use. Previously owned by United Technologies Corporation, in November 2015 Sikorsky was sold to Lockheed Martin

American Fixed Wing Aircraft (1919 - 1942) Sikorsky S-28 Year Designed: 1919 First Flight: Did Not Fly Quantity Built: 0 Summary: Soon after arriving in the United States, Igor Sikorsky formed the Hannevig-Sikorsky Aircraft Company with fellow Russian emigres with a plan to build an aircraft capable of transporting 12,000 lbs at 90 miles per hour. A drawing published on 06 April 1939 showed the Sikorsky S-45 North Atlantic project as a very large aerodynamically-clean high-wing cantilever monoplane with six engines. The drawing depicted.

[1] In Britain, Westland Aircraft began production in 1946 of the Westland-Sikorsky S-51 Dragonfly for the Royal Navy and the Royal Air Force, all of which were powered by a 500 hp Alvis Leonides engine. This gave an improved top speed of 103 mph and a service ceiling of 14,000 ft. In total, 133 Westland-Sikorsky Dragonfly helicopters were built.

The Evolution of a Dream: Igor Sikorsky's Flying Boats By Doug Miller. larger design which was never built named the VS-45), the airline had already committed to Boeing and its B-314. Although the Boeing had greater payload, the Sikorsky could fly faster and farther. It was a serious contender, but the market was small, and Pan Am had. On the eve of World War II, the U.S. armed forces also had procured 22 of Sikorsky's smaller, S-43 amphibious flying boats. 3 These twin-engine, 15-passenger aircraft were highly popular with commercial airlines, being able to operate from land or water. Fifty-three were built, with the Navy acquiring 15 planes and the Marine Corps another. Sikorsky, a Lockheed Martin company, introduces RAIDER X®, its concept for a fast, agile, survivable compound coaxial helicopter that will equip future aviators to address evolving peer and near-peer threats in the most difficult environments.
