Plane guard

Plane guard

The 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 performing this task are commonly referred to as the rescue destroyer or RESDES.

For ships, the plane guard is positioned at least 1,000 yards behind the carrier and either to port and clear of the carrier, or at a point intersecting the carrier's final approach line. Ships in the latter position provide the advantage of providing an additional point of reference to approaching aircraft. One of the ship's boats is prepared for launch and swung over the side, but not placed in the water. If an aircraft ditches or crashes, either while approaching the carrier to land or in the event of a failed landing, the ship proceeds to the approximate position of the aircraft, and the prepared boat is deployed to rescue the aircrew.

The plane guard role is dangerous for ships, as aircraft carriers must often change speed and direction to preserve optimum flying conditions for their aircraft, and a lack of awareness or any incorrect manoeuvres on the part of either ship can place a plane guard ship under the bows of a carrier travelling full speed. Both HMAS "Voyager" and USS "Frank E. Evans" were lost in collisions with Australian aircraft carrier HMAS "Melbourne" while incorrectly manoeuvering during plane guard duties.

Helicopters

After World War II, amphibious aircraft were experimented with for plane guard duties and search-and-rescue roles. However, helicopters were discovered to be more efficient and effective in both roles.
