The United States Navy Range and Ballistic Tables (1935) is the Bureau of Ordnance’s comprehensive firing reference for U.S. Navy guns, covering calibers from the 1-pounder to the 16-inch. The volume is divided into two parts.
Part I — Range Tables provides fourteen individual range tables (A through N), each for a specific gun and muzzle velocity. The tables give the firing data required for any range within the gun’s effective envelope: quadrant elevation, time of flight, striking velocity, striking angle, drift, danger space, and corrections for variations in muzzle velocity, atmospheric conditions, and propellant temperature. The smallest entry is Table A for the 1-pdr. at 2000 f.s. (the full table, 0–3,500 yards); the largest is Table M for the 16-inch 2600 f.s. full-charge gun, which spans 1,000 to 39,600 yards and fills 26 pages.
Part II — Ballistic Tables provides the mathematical foundation for computing range corrections. Seven tables are included: the Gav̀re retardation function Gv (Table I); altitude-density function Hv (Table II); surface density factor (Table III); ballistic density factor (Table IV); multipliers for Column 12 (Table V); extracts from the American translation of the French A.L.V.F. Tables of 1918 (Table VI); and extracts from Volume II of the U.S. Army’s Exterior Ballistic Tables Based on Numerical Integration (Table VII).
