Helicopters Against Submarines
Some ship pieces (DEH, others) have a helicopter icon. This icon indicates that the vessel carries one or more helicopters, which may be used for air search (11.0) or ASW patrol (10.9). At the start of each turn, a player must note to what missions available helicopters have been committed. Helicopter icons are treated the same as floatplanes (11.6) for air search purposes, except that the search range for helicopters is three as opposed to six. Helicopter icons not committed to air search may be used for ASW patrol; every two helicopter icons add one step of ASW aircraft to a task force’s ASW patrol (26.1). Helicopters on ASW patrol also contribute to the task force’s ASW modifier per rule 16.4.
