Timeline of the Sikorsky Aircraft Company

Igor Sikorsky’s journey took him from helicopter experiments in the backyard of his home in Kiev, Ukraine to building multi-engine aircraft as a leading aviation authority in Saint Petersburg, Russia, where he was Chief Engineer of the Russian-Baltic Railroad Car Company’s Aviation Department. He then started his career over in the United States, building his first American aircraft on a chicken farm in Long Island, New York before pioneering amphibious aircraft and the world’s first practical helicopter in Connecticut.  This timeline describes the events and locations that were key to Igor Sikorsky’s establishment of the Sikorsky Aircraft Company, starting from when he arrived in the United States in 1919.

For a short 4-month period after he arrived in the United States, Igor Sikorsky worked as the general manager and chief engineer of Hannevig-Sikorsky Aircraft Corporation before the company was dissolved.

McCook Field,
Dayton, Ohio
Igor Sikorsky received a contract at McCook Field (now Wright Patterson Air Force Base) to design two types of multi-seat aircraft with three 700hp engines. Igor completed the designs in six weeks and, with no further contract to build the aircraft, he returned to New York City.

Utgoff Farm,
Roosevelt, New York
Igor Sikorsky formed the Sikorsky Aero Engineering Corp. with a group of Russian immigrants, many of whom were former military officers, who he met while teaching mathematics and astronomy classes in New York City. Their first aircraft factory was on the farm of Igor's friend V. V. Utgoff and consisted of a wooden shed and a chicken coop. The above photograph shows Igor Sikorsky's first American aircraft, the S-29-A, under construction between the farm buildings.

Sikorsky Manufacturing Corp. moved to a rented factory location in the College Point neighborhood of Queens, New York.

With the success of the S-38 aircraft, the company needed to expand to meet production demand. Igor Sikorsky moved the company to an ideal location for producing both land and seaplanes, on South Main Street in Stratford along the Housatonic River. Seaplanes developed at this Stratford location include the S-38 through the VS-44A. The S-46 (VS-300) and S-47 (VS-316A) helicopters were also designed and tested at this location.

Although no longer the company headquarters, the Bridgeport location continues to operate and functions as a support facility.

Sikorsky Aircraft moved its headquarters to an 800,000 square foot plant on North Main Street in Stratford, Connecticut.
