Seeking information about WWII weaponry

Dear Mr. Cabrera,

Thank you for posting your request on History Hub!

We searched the National Archives Catalog and located two series titled Military Historical Files, 1945 - 1962 in the Records of the Office of the Chief of Ordnance (Record Group 156) that consists of a collection of nearly 800 studies that detail the development of specific weapons and vehicles used by the Army; and Records of John B. Russell Relating to Army Air Forces Gunnery and Bombing Assessment Programs, 1943-1946 in the Records of the Office of the Secretary of War (Record Group 107) relating to the planning, organization, and operation of a gunnery and bombing assessment unit of the Army Air Forces during  War II. For access to and/or copies, please contact the National Archives at College Park - Textual Reference (RDT2) via email at archives2reference@nara.gov.

We also suggest that you review World War II Books & Websites; List of World War II weapons of the United States; The 5 Deadliest U.S. Weapons From World War II; 11 Weapons That Won World War-II; and World War 2 Weapons for supplemental information and resources for your research topic.

We hope this is helpful. Best of luck with your research!
