Evolutions are details that involve all or a large portion of the crew in response to an emergency or special task.
Special Sea and Anchor Detail: Expert navigation along with extra manning required when a ship leaves and enters port or anchorage or in close navigational waters.
Plane Guard: Lookout for planes to ensure they are safe.
Low Visibility Detail: Additional lookouts in certain areas when visibility is bad.
Flight Quarters: Set when ship wants to launch aircraft.
Restricted Maneuvering: Used when ship is close to land.
Mine Countermeasures: Until 1971, all minesweeping was conducted by wooden-hulled boats and ships that steamed through suspected mined areas and trailed special minesweeping gear. In 1971 the helicopter came into use as a minesweeping platform, which resulted in an increase in the speed of sweeping an area and a decrease in the danger. The minesweeping helicopter is under the control of a specially trained shipboard Mine Countermeasures Helicopter Air Controller (MCMAC). H-53 helicopters are used to perform the towing.
