Here is the write up by the designer:
The night of July 31, 1944 the German battleship Tirpitz carried out exercises at sea for the last time. Three weeks later the Fleet Air Arm returned to the fray with a series of attacks under the operational codename 'Goodwood I, II, III, IV', using 5 aircraft carriers, Indefatigable, Formidable, Furious, Nabob and Trumpeter. They were determined to end the threat of the Tirpitz to the northern shipping lanes to Murmansk. The FAA, flying Barracuda divebombers, F6F Hellcats, F4F Wildcats and F4U Corsairs made repeated attacks on the Tirpitz while it was anchored in Altenfjord. Much to the dismay of the Kriegsmarine, the Luftwaffe refused to interfere with the Fleet Air Arm operations due to infighting between the offices of Dönitz and Göring. It was inevitable that the FAA was victorious, and while not sinking the Tirpitz, certainly kept it out of the war until the RAF could administer the coupe-de-grace. To ensure a more enjoyable time in this Snap Shot the Luftwaffe temporarily forget their snit with the Kriegsmarine and put fighters up to defend the Tirpitz.
