Damage Controlman 3rd Class Michael Minotti uses a Portable Exothermic Cutting Unit (PECU) on a damaged lathe, which is used for training purposes, in the machine shop of the aircraft carrier USS Ronald Reagan (CVN 76).
Functioning as airports at sea, aircraft carriers like the USS Ronald Reagan are complicated vessels. Damage controlmen help keep Navy vessels in shipshape condition. When equipment on a ship breaks, a damage controlman is the first to tackle the problem. Damage controlmen also assist with fighting fires and avoiding hazardous conditions.
