context_page_description: Operation Tungsten was a Second World War Royal Navy air raid that targeted the German battleship Tirpitz. The operation sought to damage or destroy Tirpitz at her base in Kaafjord in the far north of Norway before she could become fully operational again following a period of repairs.
  The British decision to strike Kaafjord was motivated by fears that the battleship, upon re-entering service, would attack strategically important convoys carrying supplies to the Soviet Union. Removing the threat posed by Tirpitz would also allow the Allies to redeploy the capital ships which had to be held in the North Sea to counter her. After four months of training and preparations, the British Home Fleet sailed on 30 March 1944 and aircraft launched from five aircraft carriers struck Kaafjord on 3 April. The raid achieved surprise, and the British aircraft met little opposition. Fifteen bombs hit the battleship, and strafing by fighter aircraft inflicted heavy casualties on her gun crews. Four British aircraft and nine airmen were lost during the operation.
context_section_description: The two attacks on Tirpitz largely went to plan. The airmen found the defences and geography at Kaafjord to be very similar to the Loch Eriboll training range, and one of the post-attack reports stated that the operation had been "almost an exercise which they [the aircrew] had frequently carried out before". The official historian of the Royal Navy's role in the Second World War, Stephen Roskill, also judged that the strikes were "beautifully co-ordinated and fearlessly executed". The most important discrepancy between the plans for the operation and its execution was that many pilots dropped their bombs below the specified minimum altitude of 3,000 feet (910 m) in an attempt to improve their chances of hitting Tirpitz. The shorter than optimum flight times may have meant that some of the bombs which struck the battleship lacked the necessary velocity to penetrate her deck armour. Nine Royal Navy airmen died during the raid.
  While two bombs that exploded in the water near Tirpitz opened holes in her hull and caused flooding, none of the 15 bombs that struck the battleship penetrated her main deck armour belt. As a result, her guns, magazines, and machinery did not suffer serious damage. Most of the damage to the battleship was inflicted on her superstructure and between her armoured decks. The starboard aircraft catapult and crane were destroyed, as were both Tirpitz's Arado floatplanes. The number two starboard 150-millimetre (5.9 in) gun turret was knocked out, and the number three port 150 mm turret incurred significant damage. The officers' mess and several galleys were wrecked, and the ship was filled with smoke. Tirpitz's funnel was also struck by bomb fragments that badly damaged all of the boiler intakes. While the starboard turbine was knocked out by shock damage and two of the boilers were disabled after being contaminated by salt water used for firefighting, the battleship was still capable of steaming within Kaafjord. Tirpitz's crew suffered heavy casualties in the attack. Overall, 122 sailors died and 316 were wounded; these casualties represented 15 percent of the battleship's crew. Many of the casualties were anti-aircraft gunners who were killed or wounded by machine-gun fire from the British fighters. 
  The British fighters also damaged four patrol craft and a large repair ship; the captain of an armed trawler died and 13 other sailors on board these vessels suffered wounds. Torstein Raaby of the Allied Secret Intelligence Service group in Alta reported a few hours after the raid, that no civilian casualties had resulted from the attack, and that the local population was "... extremely impressed by the bombing." A further report six days after the operation relayed that the Germans estimated that it would take months to repair the damage inflicted on Tirpitz.
  The commander of the Kriegsmarine, Grand Admiral Karl Dönitz, directed that the damage caused to Tirpitz during Operation Tungsten be repaired. Although the battleship was no longer capable of operating against Allied convoys for lack of air support, it was considered desirable to retain her in service in order to tie down Allied naval resources. Repair work began in early May after a destroyer transported equipment and workmen to Kaafjord from Germany, and Tirpitz was able to steam under her own power by 2 June. She was capable of undertaking gunnery practice by the end of June, and all repairs were completed in mid-July. During this period the battleship's anti-aircraft armament was augmented by fitting her with additional 20-millimetre (0.79 in) cannons, modifying the 150 mm guns so they could be used to attack aircraft and supplying anti-aircraft shells for her 380-millimetre (15 in) main guns. The defences of Kaafjord were also improved during this period. Additional radar stations and observation posts were established, and the number of smoke generators located around Tirpitz was increased.
  Following Operation Tungsten, British intelligence assessed that Tirpitz would be repaired within six months. Accordingly, Cunningham directed Fraser on 1
