Collection history

The plant was built in 1929 for Sikorsky aircraft manufacturing. A 1938 merger brought Vought and Sikorsky together, and the facility produced aircraft including the OS2U Kingfisher and F4U Corsair. The 1940 photographs document aircraft and engine assembly within that earlier aviation era. [CT048-S01]

The federal government purchased the property in 1951, and Avco Lycoming operated there during its engine-manufacturing era. Transfer to the Army in 1976 gave the plant its later name. Operations ended in 1998. These distinct phases connect local employment to changing defense technologies and help date photographs of the site. [CT048-S01]

The Stratford complex's successive identities give its photographs a necessary framework. A 1929 Sikorsky factory, the Vought–Sikorsky phase after 1938, and the later engine plant describe different production settings on the same property. An aircraft-assembly photograph from 1940 belongs to the aviation chapter. It should not be captioned as evidence of the later Army engine operation simply because the site eventually carried that name. [CT048-S01]

Federal purchase in 1951, Avco Lycoming's operation and transfer to the Army in 1976 connect local manufacturing to changing public ownership and defense requirements. The 1998 end of operations marks another transition, after which exterior photographs document the site's later condition. This chronology helps readers ask how buildings accommodated different technologies. It does not establish the duties of an unidentified worker or a current right to enter the property; those questions require their own sources. [CT048-S01]
