The failure of Operation Mascot convinced the commander of the Home Fleet, Admiral Sir Henry Moore, that the Fleet Air Arm's main strike aircraft, the Fairey Barracuda dive bomber, was not suited to operations against Kaafjord. As the dive bombers' slow speed gave the defenders of Kaafjord enough time to cover "Tirpitz" in a smoke screen between the time incoming raids were detected and their arrival over the target area, Moore concluded that further attacks using these aircraft would be futile. However, the Admiralty judged that repeatedly striking Kaafjord with Barracudas over a 48-hour period might wear down the German defences and exhaust the supply of fuel for "Tirpitz"s protective smoke generators. Consideration was also given to flying fast and long-ranged de Havilland Mosquito bombers off the carriers in an attempt to achieve surprise, but none of these land-based aircraft could be spared from supporting the Allied bombing of Germany. Despite his misgivings, Moore agreed to make another attempt to strike "Tirpitz".
