The Evolution of Naval Weapons is a United States government textbook by L. Sprague de Camp. It was first published in a 53-page edition by the Training Activity section of the Bureau of Naval Personnel in August 1947^[1] as NAVPERS 91066. A 1949 edition of 67 pages was designated NAVPERS 91066-A. The work was credited to the Bureau rather than de Camp. The 1947 edition was reproduced from a mixture of standard sized (8 1/2" x 11") typed and mimeographed sheets, and was stapled between blue paper covers.^[1] The 1949 edition was printed, with the illustrations integrated with the text.

The work is a 40,000-word study of the history of naval ordnance and armor^[1] and consists of twelve chapters plus a short concluding section.
