Naval Ordnance, 1937

Chapters I Through XVII

Naval Ordnance, 1937 is a comprehensive U.S. Navy ordnance textbook covering the science, design, and operation of naval weapons systems. Seventeen chapters address explosive chemistry, propellants, interior and exterior ballistics, the design and manufacture of guns and their components, mountings, recoil mechanisms, gun sights, armor, projectiles and ammunition, the Naval Proving Ground at Dahlgren, the naval landing gun, and naval small arms. The 1937 edition notes that Chapter V (Elastic Strength of Guns) was omitted; readers are referred to the 1933 edition for that material.

Scanned pages available: Chapters IV, VI–XI, and XIV are available as scanned page images in the tab.
