This ship was an illustrious-class aircraft carrier of Royal Navy. It was ordered just before World War II and completed in 1940. HMS Formidable operated mainly in the Mediterranean. After completion of battle tasks on Mediterranean tour of duties the ship took part in an Arctic convoy in October 1943 and was involved in attack on the German Battleship Tirpitz in Norway on 17 July 1944. Here you can see the photos made in 1941 by George Strock on the board of this ship in Norfolk.
