I am looking for a General Arrangement Plan of a C3 cargo ship. They were built in the US from 1939 through 1943

Dear Mr. Curran,

Thank you for posting your question to History Hub. The Cartographic holdings at the National Archives facility in College Park, MD include a series of Ship Engineering Drawings, 1942-1978 which may include C3 cargo ship plans. These are records from the Navy’s Bureau of Ships, so they may or may not include pre-modification plans. There are also some ship plans in Record Group 357 (Maritime Administration). I would suggest contacting the reference staff at carto@nara.gov for further information.

Looking at records outside of NARA, the Independence Seaport Museum in Philadelphia has a collection called Sun Shipbuilding & Dry Dock Company records which includes C3 general arrangement plans from 1940.

Best of luck with your research, and thank you for using History Hub!
