The master model was originally made many years ago but it stands up well when compared to the recent Neptun model of Indefatigable. The aircraft appear to be Sea Fury, fast piston engine aircraft. The two hangar deck design meant that they were unable to house jet aircraft with high tails and tricycle undercarriages, so Implacable and Indefatigable spent much of their life in reserve before being scrapped when the older Victorious carried on and was kept up to date.
