Plane guard
A plane guard is a warship (commonly a destroyer or frigate) or helicopter tasked to recover the aircrew of planes or helicopters which ditch or crash in the water during aircraft carrier flight operations. == Ships == For ships, the plane guard is positioned at 500 to 2000 yards behind the carrier and either directly behind the carrier, or at a point 15 degrees off to starboard, intersecting the final approach line to angled deck carriers.
