The Evolution of Naval Weapons

The Evolution of Naval Weapons is a 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 as NAVPERS 91066. A 1949 edition, expanded to 67 pages, was designated NAVPERS 91066-A. Both editions were created to the Bureau rather than de Camp.

The work is a 40,000-word study of the history of naval ordnance and armor.
