Helicopter capability depends on the flight deck's structure, regardless of the ship's overall size. The deck must carry the aircraft's weight and absorb the impact of landing, so a large hull with a lightly built deck still cannot operate a heavier helicopter. Governments can cut costs by specifying a light Lynx rather than a medium Sea King or Merlin, or by declining the strength needed for a heavy Chinook. Search-and-rescue certification raises the demand because Atlantic storm landings can resemble controlled crashes. A deck built for those loads may accept heavier aircraft than its normal specification suggests.

Flight-deck strength sets helicopter capability
An escort's aviation capability depends on a flight deck built for the landing loads of its helicopters, not simply on the ship's overall size.
