[Memorandum of Records on Armor Penetration by Projectiles]
- AI summary (β)
- This material appears to be a memorandum of numerical calculations and records concerning projectile armor penetration and warship armor and protection; penetration values, angles, thicknesses, figures apparently indicating velocity, logarithmic calculations, and tabular entries survive in fragmentary form. There are multiple references to “Navy” as a principal organization, but no personal names or specific ship names can be confirmed. The date and publication information are unknown, though numerical notations such as “2-6-12” and “1911” appear. Keywords: projectiles, armor penetration, armor, protection, Navy, warship construction, numerical calculations, logarithms, test recordsAuto-generated by Azure OpenAI gpt-5.5 from OCR text (which may contain errors) and image captions.
