text: According to the official history documented by the U.S. Navy, the fire controlman rating was established in 1941, when it was split off from the gunner's mate rating. It was actually created much earlier than this, as US Navy Muster Reports account for FC's well before then. It is commonly believed that the rate came into existence at some point in the 1930's. Fire controlmen were highly skilled technicians responsible for the operation of various forms of range finding gear, as well as the solving of ballistics calculations to control the firing of the ship's guns. These skills were employed initially for naval gunfire support and surface combat, but during World War II, their responsibilities expanded into anti-aircraft warfare as well.
  The fire controlman's creed
  In addition to being competent to perform any operation, I will strive to know my maintenance duties so well that I may maintain the battle efficiency of my ship, even on a darkened ship, under enemy fire. This to the end … that the ship may fight as long as she is afloat!
