Dear Mr. Hall,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located the Alphabetical Series of Ship Engineering Drawings, 1789 - 1967 in the Records of the Bureau of Ship (Record Group 19) that includes Plans for the Battleship USS Massachusetts (BB-59). Unfortunately, these plans have not digitized. For more information about the non-digitized plans, please contact the National Archives at College Park - Cartographic (RDSC) at email@example.com.
Due to the COVID-19 pandemic and pursuant to guidance received from the Office of Management and Budget (OMB), NARA has adjusted its normal operations to balance the need of completing its mission-critical work while also adhering to the recommended social distancing for the safety of NARA staff. As a result of this re-prioritization of activities, you may experience a delay in receiving an initial acknowledgement as well as a substantive response to your reference request from RDSC. We apologize for this inconvenience and appreciate your understanding and patience.
We hope this is helpful. Best of luck with your research!
