Company «Sikorsky Aircraft» began designing amphibian in the early 30-ies of the last century. The new aircraft was to carry transatlantic flights, carrying on its board a sufficiently large number of passengers, and also used for the transportation of large and heavy loads. With the onset of World War II, the aircraft model Sikorsky VS-44 was positioned as a military bomber, and, the aircraft structure is practically not changed - aircraft manufacturers merely provided an opportunity for securing and disposal of bombs, however, in this respect, the aircraft has not had the luck operated.

For its time, the plane was really unique, because at relatively low cost of operation, can carry out the transport of large numbers of people, performing flights on of extended distances limits the distance in 6120 kilometers, thus, aircraft manufacturers of the company «Sikorsky Aircraft» very well qualified and have come to the creation of the aircraft, making it a truly complete and reliable.
His first flight tests of the aircraft amphibian Sikorsky VS-44 1937 has undergone in the year, at the same time, despite the fact that all tests have been successfully completed, the aircraft continued to be refined, which is why, officially, this aircraft has been presented only 1942 year. In the production of the aircraft Sikorsky VS-44 was only about 2-3 years - during this period aviarazrabotchikami was built just 4 aircraft of this model, which was due mainly to the fact that demand in the airplane, due to very high prices, provided quite low.
Depending on the layout of the cabin, in the civil version of Sikorsky VS-44 aircraft can accommodate up to 45 people, including three crew members and passengers 42, which greatly exceeded the aircraft of this era. Among other things, amphibious aircraft can take an overboard and quite bulky cargo, however, in this case the required compliance with the regulated maximum take-off weight of the aircraft, component 26500 kg.
The power plant of the aircraft Sikorsky VS-44 consists of four radial 14-cylinder aircraft engine brand Pratt & Whitney R-1830-S1C3-G, each of which had its own thrust in 1200 hp, provided the aircraft and high rate of duty. Maximum amphibious aircraft airspeed is 305 km \ h. However, because of the danger of overheating engines, often flights were carried out at a cruising speed of 260 km \ h.
