s in early 1941, Tirpitz briefly served as the centerpiece of the Baltic Fleet, which was intended to prevent a possible breakout attempt by the Soviet Baltic Fleet. In early 1942, the ship sailed to Norway to act as a deterrent against an Allied invasion. While stationed in Norway, Tirpitz could also be used to intercept Allied convoys to the Soviet Union; two such missions were attempted in 1942, but both failed. Despite her inability to attack the convoys directly, Tirpitz acted as a fleet in being

 for the voyage. She was moored next to a cliff, which protected the ship from air attacks from the southwest. The ship's crew cut down trees and placed them aboard Tirpitz to camouflage her. Additional antiaircraft batteries were installed around the fjord, as were anti-torpedo nets and heavy booms in the entrance to the anchorage. Life for the crew of Tirpitz was very monotonous during the deployment to Norway. Frequent fuel shortages curtailed training and kept the battleship and her escorts moored behind their protective netting. The crew was primarily occupied with maintaining the ship and continuously manning antiaircraft defenses. Sports activities were organized to keep the crew occupied and physically fit.

Operations against Allied convoys

Several factors served to restrain Tirpitzs freedom of operation in Norway. The most pressing were shortages of fuel and the withdrawal of the German destroyer forces to support Operation Cerberus

The actions of Tirpitz and her escorting destroyers in March used up some 8230 metric tons (8,100 LT) of fuel oil, which greatly reduced the available fuel supply.

This was the first and only time the ship fired her main battery at an enemy target. The force landed an assault force that destroyed shore installations and captured 74 prisoners. By 11:00, the battleships had destroyed their targets and began the return to their Norwegian ports.

British attacks on Tirpitz

Operation Source
The British were determined to neutralize Tirpitz and remove the threat it posed to Allied lines of communication in the Arctic. Following the repeated, ineffectual bombing attacks and the failed Chariot attack in October 1942, the British turned to the newly designed X Craft

 to the bottom of the target. Ten vessels were assigned to the operation, scheduled for 20–25 September 1943. Only eight of the vessels reached Norway for the attack, which began early on 22 September. Three of the vessels, X5, X6, and X7, successfully breached Tirpitzs defences, two of which—X6 and X7—managed to lay their mines. X5 was detected some 200 m (656.2 ft) from the nets and sunk by a combination of gunfire and depth charges.

The mines caused extensive damage to the ship; the first exploded abreast of turret Caesar and the second detonated 45 metre off the port bow. A fuel oil tank was ruptured, shell plating was torn, a large indentation was formed in the bottom of the ship and bulkheads in the double bottom

 buckled. Some 1430 MT (1,407.4 LT) of water flooded the ship in fuel tanks and void spaces in the double bottom of the port side, which caused a list of one to two degrees, though this was balanced by counter-flooding on the starboard side. The flooding damaged all of the turbo-generators in generator room No. 2, and all save one generator in generator room No. 1 were disabled by broken steam lines or severed power cables. Turret Dora was thrown from its bearings and could not be trained; this was particularly significant, as there were no heavy-lift cranes in Norway powerful enough to lift the turret and place it back on its bearings.

 floatplanes were thrown by the explosive concussion and completely destroyed. Repairs were conducted by the repair ship Neumark; historians Robert Garzke and Robert Dulin remarked that the successful repair effort was "one of the most notable feats of naval engineering during the Second World War." Repairs lasted until 2 April 1944; full speed trials were scheduled for the following day in Altafjord.

Operation Tungsten

The British were aware that Neumark and the repair crews left in March, which intimated Tirpitz was nearly operational. A major air strike—Operation Tungsten

—involving the fleet carriers Victorious and and the escort carriers , , , and , was scheduled for 4 April 1944. Enigma decrypts revealed to the British that Tirpitz was scheduled to depart at 05:29 on 3 April for sea trials; the British therefore moved the attack forward to 3 April. The attack consisted of 40 dive-bombers and 40 escorting fighters in two waves; fifteen direct hits and two near misses were scored by the bombers, with the loss of only one aircraft in the first wave. This was due to the surprise achieved by the carrier aircraft; it took twelve to fourteen minutes for all of Tirpitzs antiaircraft batteries to be fully manned. The first wave struck at 05:29, as tugs were preparing to assist the ship out of her mooring. The second wave arrived over the target an hour later, shortly after 06:30. Despite the alertness of the German antiaircraft gunners, only one other bomber was shot down.

The air strike caused significant damage to the ship and inflicted serious casualties. William Garzke and Robert Dulin report the attack killed 122 men and wounded 316 others, while Hildebrand, Röhr, & Steinmetz report 132 fatalities and 270 wounded men, including the ship's commander, KzS Hans Meyer. Two of the 15 cm turrets were destroyed by bombs and both Ar 196 floatplanes were destroyed. Several of the bomb hits caused serious fires aboard the ship. Concussive shock disabled the starboard turbine engine and saltwater used to fight the fires reached the boilers and contaminated the feed water. Some 2000 MT (1,968.4 LT) of water flooded the ship, primarily through the two near misses, which holed the side shell with splinters. Water used to fight the fires also contributed to the flooding. Dönitz ordered the ship be repaired, regardless of the cost, despite the fact that he understood Tirpitz could no longer be used in a surface action due to insufficient fighter support. Repair work began in early May; destroyers ferried important equipment and workers from Kiel to Altafjord over the span of three days. By 2 June, the ship was again able to steam under her own power, and by the end of the month gunnery trials were possible. During the repair process, the 15 cm guns were modified to allow their use against aircraft, and specially-fuzed 38 cm shells for barrage antiaircraft fire were supplied.

Operations Planet, Brawn, Tiger Claw, Mascot, and Goodwood
A series of carrier strikes were planned over the next three months, though bad weather forced their cancellation. A repeat of Operation Tungsten, codenamed Operation Planet, was scheduled for 24 April. Operation Brawn, which was to have been carried out by 27 bombers and 36 fighters from Victorious and Furious, was to have taken place on 15 May, and Operation Tiger Claw was intended for 28 May. Victorious and Furious were joined by for Operation Mascot, which was to have been carried out on 17 July by 62 bombers and 30 fighters. The weather finally broke in late August, which saw the Goodwood series of attacks. Operations Goodwood I and II were launched on 22 August; a carrier force consisting of the fleet carriers Furious, Indefatigable, and the escort carriers , and launched a total of 38 bombers and 43 escort fighters between the two raids. The attacks failed to inflict any damage on Tirpitz, and three of the attacking aircraft were shot down. Goodwood III followed on 24 August, composed of aircraft from the fleet carriers only. Forty-eight bombers and 29 fighters attacked the ship and scored two hits which caused minor damage. One of the bombs penetrated the upper and lower armour decks and came to rest in the No. 4 switchboard room, though its fuse had been damaged and the bomb did not detonate. Six planes were shot down in the attack. Goodwood IV followed on the 29th, with 34 bombers and 25 fighters from Formidable and Indefatigable, though heavy fog interfered with the attack and prevented any hits from being scored. One Firefly

 in Russia, 23 Lancasters (17 each carrying one Tallboy and six each carrying twelve JW mines), scored a single hit on the ship's bow. The Tallboy completely penetrated the ship, exited the keel, and exploded in the bottom of the fjord. Some 800 metric ton of water flooded the bow and caused a serious increase in trim forward. The ship was rendered unseaworthy and was limited to 8 knot. Concussive shock caused severe damage to fire-control equipment. The heavy damage persuaded the naval command to repair the ship for use only as a floating gun battery. Repair work was estimated to take nine months, but patching of the holes could be effected within a few weeks, which would allow Tirpitz to be moved further south to Tromsø

 and No. 617 Squadron carried out the attack together, which resulted in only one near-miss, partially the result of bad weather over the target. The underwater explosion damaged the port rudder and shaft and caused some flooding. Tirpitzs 38 cm fragmentation shells proved ineffective in countering the high-level bombers, though one aircraft was damaged by ground-based antiaircraft guns. Following the attack, the ship's anchorage was significantly improved. A large sand bank was constructed under and around the ship to prevent her from capsizing and anti-torpedo nets were installed. Tirpitz retained a one-degree list to port from earlier damage, and this was not corrected by counter-flooding to retain as much reserve buoyancy as possible. The ship was also prepared for her role as a floating artillery platform: fuel was limited to only what was necessary to power the turbo-generators and the crew was reduced to 1,600 officers and enlisted men.

, the final British attack on Tirpitz, took place on 12 November 1944. The ship again used her 38 cm guns against the bombers, which approached the battleship at 09:35; Tirpitzs main guns forced the bombers to temporarily disperse, but could not break up the attack. A force of 32 Lancasters from Nos 9 and 617 Squadrons dropped 29 Tallboys on the ship, with two direct hits and one near miss. Several other bombs landed within the anti-torpedo net barrier and caused significant cratering of the seabed; this removed much of the sandbank that had been constructed to prevent the ship from capsizing. One bomb penetrated the ship's deck between turrets Anton and Bruno but failed to explode. A second hit amidships between the aircraft catapult and the funnel and caused severe damage. A very large hole was blown into the ship's side and bottom; the entire section of belt armour abreast of the bomb hit was completely destroyed. A third bomb may have struck the ship on the port side of turret Caesar. The amidships hit caused significant flooding and quickly increased the port list to between 15 and 20 degrees. In ten minutes, the list increased to 30 to 40 degrees; the captain issued the order to abandon ship. Progressive flooding increased the list to 60 degrees by 09:50, though this appeared to stabilize temporarily. Eight minutes later, a massive explosion rocked turret Caesar. The turret roof and part of the rotating structure were thrown 25 m (82 ft) into the air and over into a group of men swimming to shore. Tirpitz then rapidly rolled over and buried her superstructure in the sea floor.

In the aftermath of the attack, rescue operations attempted to reach men trapped in the hull. Workers managed to rescue 82 men by cutting through the bottom hull plates. Figures for the death toll vary; John Sweetman states that 1,000 out of a crew of 1,900 were killed, while Niklas Zetterling and Michael Tamelander estimated nearly 1,000 fatalities. Siegfried Breyer and Erich Gröner both agree on 1,204 deaths, though Gordon Williamson gives the death toll at 971. William Dulin and Robert Dulin place the number of deaths at "about 950." The wreck remained in place until after the war, when a joint German-Norwegian company began salvage operations. Work lasted from 1948 until 1957; fragments of the ship are still sold by a Norwegian company.
