Designed to accompany, and be used by, the Flight Replicas Seafire package (but can be used with any aircraft), these two 23000 ton aircraft carriers, HMS Indomitable and HMS Formidable, formed an important part of the British Royal Navy fleet during WW2. The carriers operated around the world during this time, and some six locations in MSFS can be chosen to fly from as but a small representation of the places around the world where these ships could be found.
