Task: Question Answering
Input (English): Following Operation Tungsten, British intelligence assessed that Tirpitz would be repaired within six months. Accordingly, Cunningham directed Fraser on 13 April to launch another attack on the battleship. While Cunningham did not believe that Barracudas could carry weapons capable of sinking Tirpitz, he hoped that further air strikes would increase the period the battleship was out of service and harm her crew's morale. Fraser initially resisted Cunningham's order, arguing that the prospects for a successful raid were poor as the Germans would have reinforced the defences around Tirpitz and weather conditions were likely to be worse than those encountered during Operation Tungsten. He eventually relented, and Moore sailed from Scapa Flow on 21 April to attack Kaafjord again. This raid, designated Operation Planet, was called off on 24 April due to bad weather over the target area. Two other attacks, Operation Brawn and Operation Tiger Claw, also had to be cancelled on 15 and 28 May respectively because of adverse weather. Further carrier raids were attempted in July and August after Allied intelligence determined that the repairs to Tirpitz were nearing completion. During Operation Mascot a force of 42 Barracudas and 40 fighters attacked Tirpitz on 17 July, but did not score any hits as the battleship was hidden by a smokescreen. A further four carrier raids were conducted against Kaafjord between 22 and 29 August during Operation Goodwood, but these caused only light damage to the battleship.In late August it was decided that further Fleet Air Arm attacks should not be attempted as the Germans were now able to cover Tirpitz in smoke before Barracudas could reach the battleship, and these aircraft could not carry bombs large enough to inflict heavy damage. As it was still seen as desirable to destroy Tirpitz, the task was assigned to Bomber Command. On 15 September a force of heavy bombers attacked Kaafjord after refuelling at bases in northern Russia and inflicted irreparable damage on the battleship. Following this, Tirpitz sailed to an anchorage near Tromsø to be used as an immobile coastal defence battery. Another heavy bomber attack on 29 October caused only minor damage, and a third raid was mounted on 12 November in which Tirpitz was struck by several Tallboy bombs and capsized with heavy loss of life among her crew.
