Folks,

Standard Fire Control Symbols, OP 1700, 1950, established a set of standard fire control symbols to be used in various U.S. Navy fire control systems.

Standard Fire Control Symbols for Underwater Related Quantities, OP 1700 Volume 2, 1957, extends the definitions beyond guns.

Standard Fire Control Symbols for Missile Related Quantities, OP 1700 Volume 3, 1957, further extends the definitions.

Please report any typos, or particularly annoying layout issues with the Mail Feedback Form for correction.
