Tirpitz (German pronunciation: [ˈtɪʁpɪt͡s] ) was the second of two Bismarck-class battleships built for Nazi Germany's Kriegsmarine (navy) prior to and during the Second World War. Named after Grand Admiral Alfred von Tirpitz, the architect of the Kaiserliche Marine (Imperial Navy), the ship was laid down at the Kriegsmarinewerft in Wilhelmshaven in November 1936 and her hull was launched two and a half years later. Work was completed in February 1941, when she was commissioned into the German fleet. Like her sister ship, Bismarck, Tirpitz was armed with a main battery of eight 38-centimetre (15 in) guns in four twin turrets. After a series of wartime modifications she was 2000 tonnes heavier than Bismarck, making her the heaviest battleship ever built by a European navy. [3]


After completing sea trials in early 1941, Tirpitz briefly served as the centrepiece of the Baltic Fleet, which was intended to prevent a possible break-out 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 was also intended to be used to intercept Allied convoys to the Soviet Union, and two such missions were attempted in 1942. This was the only feasible role for her, since the St Nazaire Raid had made operations against the Atlantic convoy lanes too risky. Tirpitz acted as a fleet in being, forcing the British Royal Navy to retain significant naval forces in the area to contain the battleship. [4]

In September 1943, Tirpitz, along with the battleship Scharnhorst, bombarded Allied positions on Spitzbergen, the only time the ship used her main battery in an offensive role. Shortly thereafter, the ship was damaged in an attack by British mini-submarines and subsequently subjected to a series of large-scale air raids. On 12 November 1944, British Lancaster bombers equipped with 12,000-pound (5,400 kg) "Tallboy" bombs scored two direct hits and a near miss which caused the ship to capsize rapidly. A deck fire spread to the ammunition magazine for one of the main battery turrets, which caused a large explosion. Figures for the number of men killed in the attack range from 950 to 1,204. Between 1948 and 1957, the wreck was broken up by a joint Norwegian and German salvage operation.


The two Bismarck-class battleships were designed in the mid-1930s by the German Kriegsmarine as a counter to French naval expansion, specifically the two Richelieu-class battleships France had started in 1935. Laid down after the signing of the Anglo-German Naval Agreement of 1935, Tirpitz and her sister Bismarck were nominally within the 35,000- long-ton (36,000  t ) limit imposed by the Washington regime that governed battleship construction in the interwar period. The ships secretly exceeded the figure by a wide margin, though before either vessel was completed, the international treaty system had fallen apart following Japan's withdrawal in 1937, allowing signatories to invoke an "escalator clause" that permitted displacements as high as 45,000 long tons (46,000 t). [5]

Tirpitz displaced 42,900 t (42,200 long tons) as built and 52,600 t (51,800 long tons) fully loaded, with a length of 251 m (823 ft 6 in), a beam of 36 m (118 ft 1 in) and a maximum draft of 10.60 m (34 ft 9 in). [lower-alpha 3] Her standard crew numbered 103 officers and 1,962 enlisted men; during the war this was increased to 108 officers and 2,500 men. She was powered by three Brown, Boveri & Cie geared steam turbines, each driving a screw propeller, with steam provided by twelve oil-fired Wagner superheated water-tube boilers. Her propulsion system developed a total of 163,023  PS (160,793  shp ; 119,903  kW ) and yielded a maximum speed of 30.8 knots (57.0 km/h; 35.4 mph) on speed trials. [7]

She was armed with eight 38 cm SK C/34 L/52 guns arranged in four twin gun turrets: two superfiring turrets forward—Anton and Bruno—and two aft—Caesar and Dora. [lower-alpha 4] Her secondary armament consisted of twelve 15 cm L/55 guns, sixteen 10.5 cm L/65 and sixteen 3.7 cm (1.5 in) L/83, and initially twelve 2 cm (0.79 in) C/30 anti-aircraft guns. The number of 2 cm guns was eventually increased to 58. After 1942, eight 53.3 cm (21 in) above-water torpedo tubes were installed in two quadruple mounts, one mount on each side of the ship. [2]

As built, Tirpitz was equipped with Model 23 search radars [lower-alpha 5] mounted on the forward, foretop, and rear rangefinders. These were later replaced with Model 27 and then Model 26 radars, which had a larger antenna array. A Model 30 radar, known as the Hohentwiel , was mounted in 1944 in her topmast, and a Model 213 Würzburg fire-control radar was added on her stern 10.5 cm (4.1 in) Flak rangefinders. [10]

The ship's main belt was 320 mm (13 in) thick and was covered by a pair of upper and main armoured decks that were 50 mm (2 in) and 100 to 120 mm (3.9 to 4.7 in) thick, respectively. The 38 cm turrets were protected by 360 mm (14 in) thick faces and 220 mm (8.7 in) thick sides. [1]

Service history

Tirpitz was ordered as Ersatz Schleswig-Holstein as a replacement for the old pre-dreadnought Schleswig-Holstein, under the contract name "G". [1] The Kriegsmarinewerft shipyard in Wilhelmshaven was awarded the contract, where the keel was laid on 20 October 1936. [11] The hull was launched on 1 April 1939; during the elaborate ceremonies, the ship was christened by Ilse von Hassell, the daughter of Admiral Alfred von Tirpitz, the ship's namesake. [12] Adolf von Trotha, a former admiral in the Imperial German Navy, spoke at the ship's launching, which was also attended by Adolf Hitler. [13] Fitting-out work was completed by February 1941. [12] British bombers repeatedly attacked the harbour in which the ship was being built; no bombs struck Tirpitz, but the attacks slowed construction work. [14] Tirpitz was commissioned into the fleet on 25 February for sea trials, [2] which were conducted in the Baltic. [12]

After sea trials, Tirpitz was stationed in Kiel and performed intensive training in the Baltic. While the ship was in Kiel, Germany invaded the Soviet Union. A temporary Baltic Fleet was created to prevent the breakout of the Soviet fleet based in Leningrad. Tirpitz was briefly made the flagship of the squadron, which consisted of the heavy cruiser Admiral Scheer, the light cruisers Köln, Nürnberg, Leipzig, and Emden, several destroyers, and two flotillas of minesweepers. [14] The Baltic Fleet, under the command of Vice Admiral Otto Ciliax, [13] patrolled off Åland from 23 to 26 September 1941, after which the unit was disbanded and Tirpitz resumed training. [15] During the training period, Tirpitz tested her primary and secondary guns on the old pre-dreadnought battleship Hessen, [16] which had been converted into a radio-controlled target ship. [17] The British Royal Air Force (RAF) continued to launch unsuccessful bombing raids on Tirpitz while she was stationed in Kiel. [18]

Deployment to Norway

Grand Admiral Erich Raeder, the commander of the Kriegsmarine, proposed on 13 November 1941 that Tirpitz be deployed to Norway. The ship would be able to attack convoys bound for the Soviet Union, and act as a fleet in being to tie down British naval assets and deter an Allied invasion of Norway. Hitler, who had forbidden an Atlantic sortie after the loss of Bismarck, agreed to the proposal. The ship was taken into dock for modifications for the deployment. The ship's anti-aircraft battery was strengthened, and the 10.5 cm guns on the superstructure next to the catapult were moved outboard to increase their field of fire. The two quadruple 53.3 cm torpedo tube mounts were also installed during this refit. [19] The ship's commander, Kapitän zur See (KzS–Captain at Sea) Karl Topp, [20] pronounced the ship ready for combat operations on 10 January 1942. [18] The following day, Tirpitz left for Wilhelmshaven, a move designed to conceal her actual destination. [19]

The ship left Wilhelmshaven at 23:00 on 14 January and made for Trondheim. [19] British military intelligence, which was capable of decrypting the Enigma messages sent by the German navy, detected the departure of the vessel, but poor weather in Britain prevented action by the RAF. [21] Admiral John Tovey, the commander in chief of the British Home Fleet, was not made aware of Tirpitz's activities until 17 January, well after the ship had arrived in Norway. [22] On 16 January, British aerial reconnaissance located the ship in Trondheim. Tirpitz then moved to the Fættenfjord, just north-east of Trondheim. [23] The movement was codenamed Operation Polarnacht (Polar Night); the battleship was escorted by the destroyers Z4 Richard Beitzen, Z5 Paul Jakobi, Z8 Bruno Heinemann and Z29 for the voyage. [24] The Norwegian resistance movement transmitted the location to London. [25] 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. [23] The crew also frequently hid the entire ship from aerial reconnaissance and attacks inside a cloud of artificial fog, created using water and chlorosulfuric acid. [26] [27] Additional anti-aircraft batteries were installed around the fjord, as were anti-torpedo nets and heavy booms in the entrance to the anchorage. [28] Tirpitz was known as the "Lonely Queen of the North" because she was so rarely deployed, [29] and life for her crew was very monotonous. 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 anti-aircraft defences. Sports activities were organised to keep the crew occupied and physically fit. [30]

Operations against Allied convoys

Several factors hindered Tirpitz's 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 movement of the battleships Scharnhorst and Gneisenau and the heavy cruiser Prinz Eugen through the English Channel. These caused a planned attack against the outbound convoy PQ 8 at the end of January to be abandoned. [31] A planned British air attack at the end of January by four-engined heavy bombers was disrupted by poor weather over the target, which prevented the aircraft from finding the ship. [32] In early February, Tirpitz took part in the deceptions that distracted the British in the run-up to Operation Cerberus. These included steaming out of the fjord and the appearance of preparations for a sortie into the North Sea. [33] Later that month, the ship was reinforced by the heavy cruisers Admiral Scheer and Prinz Eugen and several destroyers. Prinz Eugen had been torpedoed by a British submarine at the entrance to the Fættenfjord, and was temporarily out of action. [34]

In March 1942 Tirpitz and Admiral Scheer, along with the destroyers Z14 Friedrich Ihn, Z5 Paul Jakobi, Z7 Hermann Schoemann and Z25 and a pair of torpedo boats, [24] were intended to attack the homebound convoy QP 8 and the outbound Convoy PQ 12 as part of Unternehmen Sportpalast (Operation Sports Palace). [31] [35] Admiral Scheer, [31] with a design speed of 26 knots (48 km/h; 30 mph), [36] was too slow to operate with Tirpitz and was left in port, [31] as was the destroyer Paul Jakobi. The two torpedo boats were also released from the operation. [24] On 5 March, Luftwaffe reconnaissance aircraft spotted PQ 12 near Jan Mayen Island; the reconnaissance failed to note the battleship HMS Duke of York or the battlecruiser HMS Renown, both of which were escorting the convoy, along with four destroyers. [31]

Unknown to the Germans, Admiral Tovey was providing distant support to the convoys with the battleship HMS King George V, the aircraft carrier HMS Victorious, the heavy cruiser HMS Berwick, and six destroyers. Enigma intercepts again forewarned the British of Tirpitz's attack, which allowed them to reroute the convoys. Admiral Tovey attempted to pursue Tirpitz on 9 March, [31] but Admiral Otto Ciliax, the commander of the German squadron, had decided to return to port the previous evening. An air attack was launched early on the 9th; twelve Fairey Albacore torpedo bombers attacked the ship in three groups, and Tirpitz successfully evaded the torpedoes. Only three men were wounded in the attack. [37] Tirpitz's anti-aircraft gunners shot down two of the British aircraft. [38] After the conclusion of the attack, Tirpitz made for Vestfjord, and from there to Trondheim, arriving on the evening of 13 March. [39] On 30 March, thirty-three Halifax bombers attacked the ship; they scored no hits, and five aircraft were shot down. [40] The RAF launched a pair of unsuccessful strikes in late April. On the night of 27–28 April, thirty-one Halifaxes and twelve Lancasters attacked; five of the bombers were shot down. Another raid, composed of twenty-three Halifaxes and eleven Lancasters, took place the following night. Two of the bombers were shot down by the German anti-aircraft defences. [41]

The actions of Tirpitz and her escorting destroyers in March used up 8,230 tonnes (8,100 long tons) of fuel oil, which greatly reduced the available fuel supply. It took the Germans three months to replenish the fuel spent in the attempt to intercept the two Allied convoys. Convoy PQ 17, which left Iceland on 27 June bound for the Soviet Union, was the next convoy targeted by Tirpitz and the rest of the German fleet stationed in Norway, [39] during Unternehmen Rösselsprung (Operation Knight's Move). [42] Escorting the convoy were the battleships Duke of York and USS Washington and the carrier Victorious. [39] Tirpitz, Admiral Hipper, and six destroyers sortied from Trondheim, while a second task force consisting of Lützow, Admiral Scheer, and six destroyers operated from Narvik and Bogenfjord. [43] Lützow and three of the destroyers struck uncharted rocks while en route to the rendezvous and had to return to port. Shortly after Tirpitz left Norway, the Soviet submarine K-21 fired two or four torpedoes at the ship, all of which missed. [44] [45] The Soviets claimed two hits on the battleship. [46] Swedish intelligence had meanwhile reported the German departures to the British Admiralty, which ordered the convoy to disperse. Aware that they had been detected, the Germans aborted the operation and turned over the attack to U-boats and the Luftwaffe. The scattered vessels could no longer be protected by the convoy escorts, and the Germans sank 21 of the 34 isolated transports. Tirpitz returned to Altafjord via the Lofoten Islands. [44]

Following Rösselsprung, the Germans moved Tirpitz to Bogenfjord near Narvik. By this time, the ship needed a major overhaul. Hitler had forbidden the ship to make the dangerous return to Germany, and so the overhaul was conducted in Trondheim. On 23 October, the ship left Bogenfjord and returned to Fættenfjord outside Trondheim. The defences of the anchorage were further strengthened; additional anti-aircraft guns were installed, and double anti-torpedo nets were laid around the vessel. The repairs were conducted in limited phases, so Tirpitz would remain partially operational for the majority of the overhaul. A caisson was built around the stern to allow the replacement of the ship's rudders. [44] During the repair process, the British attempted to attack the battleship with two Chariot human torpedoes, but before they could be launched, rough seas caused them to break away from the fishing vessel which was towing them. [47] By 28 December, the overhaul had been completed, and Tirpitz began sea trials. She conducted gunnery trials on 4 January 1943 in Trondheim Fjord. [48] On 21 February, Topp was promoted to Rear Admiral and was replaced by Captain Hans Meyer; five days later the battleship Scharnhorst was ordered to reinforce the fleet in Norway. Vice Admiral Oskar Kummetz was given command of the warships stationed in Norway. [49]

By the time Scharnhorst arrived in Norway in March 1943, Allied convoys to the Soviet Union had temporarily ceased. To give the ships an opportunity to work together, Admiral Karl Dönitz, who had replaced Raeder in the aftermath of the Battle of the Barents Sea on 31 December 1942, ordered an attack on Spitzbergen, which housed a British weather station and refuelling base. [48] Spitzbergen was defended by a garrison of 152 men from the Norwegian Armed Forces in exile. [50] The two battleships, escorted by ten destroyers, left port on 6 September; in a ruse de guerre , Tirpitz flew the white ensign on the approach to the island the following day. [51] During the bombardment, Tirpitz fired 52 main-battery shells and 82 rounds from her 15 cm secondaries. [52] This was the first and only time the ship fired her main battery at an enemy surface target. [48] An assault force destroyed shore installations and captured 74 prisoners. [50] [53] By 11:00, the battleships had destroyed their targets and headed back to their Norwegian ports. [48]

British attacks on Tirpitz

Operation Source

The British were determined to neutralise Tirpitz and remove the threat she posed to the Allied arctic convoys. Following the repeated, ineffectual bombing attacks and the failed torpedo attack in October 1942, the British turned to the newly designed X Craft midget submarines. [48] The planned attack, Operation Source, included attacks on Tirpitz, Scharnhorst, and Lützow. [54] The X Craft were towed by large submarines to their destinations, where they could slip under anti-torpedo nets and each drop two powerful two-tonne mines onto the sea bed under the target. Ten vessels were assigned to the operation, scheduled for 20–25 September 1943. Only eight of them reached Kåfjord in Norway for the attack, which began early on 22 September. [48] Three of the vessels, X5, X6, and X7, successfully breached Tirpitz's defences, two of which—X6 and X7—managed to lay their mines. X5 was detected 200 m (660 ft) from the nets and sunk by a combination of gunfire and depth charges. [55]

The mines damaged the ship extensively. The first exploded abreast of turret Caesar, and the second detonated 45 to 55 m (148 to 180 ft) off the port bow. [56] 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 1,430 t (1,410 long tons) 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, which was balanced by counter-flooding on the starboard side. The flooding damaged all of the turbo-generators in generator room No. 2, and all apart from 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 rotated; 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. [57] The ship's two Arado Ar 196 floatplanes were completely destroyed. Repairs were conducted by the repair ship Neumark; historians William 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". [58] Repairs lasted until 2 April 1944; full speed trials were scheduled for the following day in Altafjord. [59]

Operation Tungsten

The British were aware that Neumark and the repair crews left in March, which intimated Tirpitz was nearly operational. [59] A major air strike—Operation Tungsten—involving the fleet carriers Victorious and Furious and the escort carriers Emperor, Fencer, Pursuer, and Searcher, [60] was set for 4 April 1944, but rescheduled a day earlier when Enigma decrypts revealed that Tirpitz was to depart at 05:29 on 3 April for sea trials. [59] The attack consisted of 40 Barracuda dive-bombers carrying 500-pound (230 kg), 600-pound (270 kg) and 1,600-pound (730 kg) armour-piercing bombs and 40 escorting fighters in two waves, scoring fifteen direct hits and two near misses. [60] [61] The aircraft achieved surprise, and only one was lost in the first wave; it took twelve to fourteen minutes for all of Tirpitz''s anti-aircraft 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 anti-aircraft gunners, only one other bomber was shot down. [62]

The air strikes did not penetrate the main armour but nonetheless caused significant damage to the ship's superstructure and inflicted serious casualties. William Garzke and Robert Dulin report the attack killed 122 men and wounded 316 others, [62] while Hildebrand, Röhr, & Steinmetz report 132 fatalities and 270 wounded men, including the ship's commander, KzS Hans Meyer. [63] 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 2,000 t (2,000 long tons) of water flooded the ship, primarily through the two holes in the side shell created by shell splinters from near misses. Water used to fight the fires also contributed to the flooding. [64] 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 because of 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 anti-aircraft fire were supplied. [65]

Operations Planet, Brawn, Tiger Claw, Mascot and Goodwood

A series of carrier strikes was planned over the next three months, but 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. Formidable and Furious were joined by Indefatigable for Operation Mascot, which was carried out in bad weather on 17 July by 62 bombers and 30 fighters. In late August the weather improved, allowing 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 Formidable and the escort carriers Nabob and Trumpeter launched a total of 38 bombers and 43 escort fighters between the two raids. [60]

The attacks failed to inflict any damage on Tirpitz and three of the attacking aircraft were shot down. [60] [65] 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. [60] One, a 1,600-pound bomb, penetrated the upper and lower armour decks and came to rest in the No. 4 switchboard room. Its fuze had been damaged and the bomb did not detonate. The second, a 500-pound (230 kg) bomb, exploded causing superficial damage. Six aircraft were shot down in the attack. [66] [67] Goodwood IV followed on 29 August, with 34 bombers and 25 fighters from Formidable and Indefatigable. Heavy fog prevented any hits from being scored. [60] Tirpitz's gunners shot down one Firefly and a Corsair. The battleship expended 54 rounds from her main guns, 161 from the 15 cm guns and up to 20 per cent of her light anti-aircraft ammunition. [68]

Operations Paravane and Obviate

The ineffectiveness of the great majority of the strikes launched by the Fleet Air Arm in mid-1944 led to the task of Tirpitz's destruction being transferred to the RAF's No. 5 Group. The RAF used Lancaster bombers to carry 6-short-ton (5.4 t) Tallboy bombs to penetrate the ship's heavy armour. [69] The first attack, Operation Paravane, took place on 15 September 1944; operating from a forward base at Yagodnik 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. [60] The Tallboy penetrated the ship, exited the keel, and exploded in the bottom of the fjord. The bow was flooded with 800 to 1,000 t (790 to 980 long tons) of water, causing a serious increase in trim forward. The ship was rendered unseaworthy and was limited to 8 to 10 knots (15 to 19 km/h; 9.2 to 11.5 mph). Concussive shock caused severe damage to fire-control equipment. The 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, allowing Tirpitz to be moved further south to Tromsø. On 15 October, the ship made the 200 nmi (370 km; 230 mi) trip to Tromsø under her own power, the last voyage of her career. [70]

The RAF made a second attempt on 29 October, after the ship was moored off Håkøya Island outside Tromsø. Thirty-two Lancasters attacked the ship with Tallboys during Operation Obviate. [60] As on Operation Paravane, No. 9 Squadron and No. 617 Squadron carried out the attack together, which resulted in only one near miss, [70] partially the result of bad weather over the target. [71] The underwater explosion damaged the port rudder and shaft and caused some flooding. Tirpitz's 38 cm fragmentation shells proved ineffective in countering the high-level bombers; one aircraft was damaged by ground-based anti-aircraft guns. [70] Following the attack, the ship's anchorage was significantly improved. A large sandbank 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 what was necessary to power the turbo-generators, and the crew was reduced to 1,600 officers and enlisted men. [72]

Operation Catechism

Universal Newsreel about the attack on Tirpitz

Operation Catechism, the final British attack on Tirpitz, took place on 12 November 1944. [60] The ship again used her 38 cm guns against the bombers, which approached the battleship at 09:35; Tirpitz's main guns forced the bombers to disperse temporarily, but could not break up the attack. [73] A force of 32 Lancasters from Nos. 9 and 617 Squadrons dropped 29 Tallboys on the ship, landing two direct hits and one near miss. [60] 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 in 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 port side of turret Caesar. [73]

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, and the captain issued the order to abandon ship. The list increased to 60 degrees by 09:50; this appeared to stabilise temporarily. Eight minutes later, a large explosion rocked turret Caesar. The turret roof and part of the rotating structure were thrown 25 m (82 ft) into the air and into a group of men swimming to shore, crushing them. Tirpitz rapidly rolled over and buried her superstructure in the sea floor. [74] In the aftermath of the attack, 82 men trapped in the upturned hull were rescued by cutting through the exposed bottom. [60] Figures for the death toll vary from approximately 950 to 1,204. [lower-alpha 6] Approximately 200 survivors of the sinking were transferred to the heavy cruiser Lützow in January 1945. [77]

The performance of the Luftwaffe in the defence of Tirpitz was heavily criticised after her loss. Major Heinrich Ehrler, the commander of III./Jagdgeschwader 5 (3rd Wing of the 5th Fighter Group), was blamed for the Luftwaffe's failure to intercept the British bombers. He was court-martialled in Oslo and threatened with the death penalty. Evidence was presented that his unit had failed to help the Kriegsmarine when requested. He was sentenced to three years in prison, but was released after a month, demoted, and reassigned to an Me 262 fighter squadron in Germany. [78] Ehrler was exonerated by further investigations which concluded poor communication between the Kriegsmarine and the Luftwaffe had caused the fiasco; [79] the aircrews had not been informed that Tirpitz had been moved off Håkøya two weeks before the attack. [80] The wreck of Tirpitz remained in place until after the war, when a joint German-Norwegian company began salvage operations. Work lasted from 1948 until 1957; [2] fragments of the ship were sold by a Norwegian company. [20] Ludovic Kennedy wrote in his history of the vessel that she "lived an invalid's life and died a cripple's death". [81]


  1. Tirpitz's draft at full load was 10.60 metres (34 ft 9 in). [1]
  2. Crew could be augmented up to 108 officers and 2,500 enlisted men. [2]
  3. According to naval historians Gerhard Koop and Klaus-Peter Schmolke, Tirpitz displaced 53,500 tonnes (52,700 long tons) at full load in 1944. [6]
  4. SK stands for Schiffskanone (ship's gun), C/34 stands for Constructionjahr (Construction year) 1934, and L/52 denotes the length of the gun in terms of calibres, meaning that the length of the gun is 52 times its internal diameter. [8]
  5. Named FuMO for Funkmessortungsgerät (Radio direction-finding device). [9]
  6. John Sweetman states that 1,000 out of a crew of 1,900 were killed, [75] while Niklas Zetterling and Michael Tamelander estimated nearly 1,000 deaths. [76] Siegfried Breyer and Erich Gröner agree on 1,204 deaths, [2] [60] and Gordon Williamson gives the death toll at 971. [20] William Garzke and Robert Dulin place the number of deaths at "about 950". [74]

Bismarck was the first of two Bismarck-class battleships built for Nazi Germany's Kriegsmarine. Named after Chancellor Otto von Bismarck, the ship was laid down at the Blohm & Voss shipyard in Hamburg in July 1936 and launched in February 1939. Work was completed in August 1940, when she was commissioned into the German fleet. Bismarck and her sister ship Tirpitz were the largest battleships ever built by Germany, and two of the largest built by any European power.

Japanese battleship <i>Yamato</i> Imperial Japanese Navy ship

Yamato (大和) was the lead ship of her class of battleships built for the Imperial Japanese Navy (IJN) shortly before World War II. She and her sister ship, Musashi, were the heaviest and most powerfully armed battleships ever constructed, displacing nearly 72,000 tonnes at full load and armed with nine 46 cm (18.1 in) Type 94 main guns, which were the largest guns ever mounted on a warship.

<i>King George V</i>-class battleship (1939) 1939 class of battleships of the Royal Navy

The King George V-class battleships were the most modern British battleships in commission during the Second World War. Five ships of this class were built: HMS King George V, HMS Prince of Wales (1941), HMS Duke of York (1941), HMS Anson (1942) and HMS Howe (1942). The names honoured King George V, and his sons, Edward VIII, who had been Prince of Wales, and George VI who was Duke of York before ascending to the throne; the final two ships of the class were named after prominent 18th century admirals of the Royal Navy.

HMS <i>Duke of York</i> (17) King George V-class battleship of the Royal Navy

HMS Duke of York was a King George V-class battleship of the Royal Navy. Laid down in May 1937, the ship was constructed by John Brown and Company at Clydebank, and commissioned into the Royal Navy on 4 November 1941, subsequently seeing combat service during the Second World War. In mid-December 1941, Duke of York transported Prime Minister Winston Churchill to the United States to meet President Franklin D. Roosevelt. Between March and September 1942 Duke of York was involved with convoy escort duties, including as flagship of the Heavy Covering Force of Convoy PQ-17, but in October she was dispatched to Gibraltar where she became the flagship of Force H.

German cruiser <i>Prinz Eugen</i> Admiral Hipper-class cruiser

Prinz Eugen was an Admiral Hipper-class heavy cruiser, the third of a class of five vessels. She served with Nazi Germany's Kriegsmarine during World War II. The ship was laid down in April 1936, launched in August 1938, and entered service after the outbreak of war, in August 1940. She was named after Prince Eugene of Savoy, a distinguished 18th-century general in the service of the Holy Roman Empire. She was armed with a main battery of eight 20.3 cm (8 in) guns and, although nominally under the 10,000-long-ton (10,160 t) limit set by the Anglo-German Naval Agreement, actually displaced over 16,000 long tons (16,257 t).

German cruiser <i>Admiral Hipper</i> Lead ship of titular class of heavy cruisers

Admiral Hipper was the lead ship of the Admiral Hipper class of heavy cruisers which served with Nazi Germany's Kriegsmarine during World War II. The ship was laid down at the Blohm & Voss shipyard in Hamburg in July 1935 and launched February 1937; Admiral Hipper entered service shortly before the outbreak of war, in April 1939. The ship was named after Admiral Franz von Hipper, commander of the German battlecruiser squadron during the Battle of Jutland in 1916 and later commander-in-chief of the German High Seas Fleet. She was armed with a main battery of eight 20.3 cm (8 in) guns and, although nominally under the 10,000-long-ton (10,160 t) limit set by the Anglo-German Naval Agreement, actually displaced over 16,000 long tons (16,260 t).

Italian battleship <i>Vittorio Veneto</i> Fast battleship of the Italian Royal Navy

Vittorio Veneto was the second member of the Littorio-class battleship that served in the Italian Regia Marina during World War II. The ship's keel was laid down in October 1934, launched in July 1937, and readied for service with the Italian fleet by August 1940. She was named after the Italian victory at Vittorio Veneto during World War I, and she had three sister ships: Littorio, Roma, and Impero, though only Littorio and Roma were completed during the war. She was armed with a main battery of nine 381-millimeter (15.0 in) guns in three triple turrets, and could steam at a speed of 30 knots.

Italian battleship <i>Littorio</i> Fast battleship of the Italian Royal Navy

Littorio was the lead ship of her class of battleship; she served in the Italian Regia Marina during World War II. She was named after the Lictor, in ancient times the bearer of the Roman fasces, which was adopted as the symbol of Italian Fascism. Littorio and her sister Vittorio Veneto were built in response to the French battleships Dunkerque and Strasbourg. They were Italy's first modern battleships, and the first 35,000-ton capital ships of any nation to be laid down under the terms of the Washington Naval Treaty. Littorio was laid down in October 1934, launched in August 1937, and completed in May 1940.

<i>Scharnhorst</i>-class battleship Kriegsmarine battleship class, built 1935–1939

The Scharnhorst class was a class of German battleships built immediately prior to World War II. The first capital ships of Nazi Germany's Kriegsmarine, it comprised two vessels: Scharnhorst and Gneisenau. Scharnhorst was launched first, and is considered to be the lead ship by some sources; they are also referred to as the Gneisenau class in some other sources, as Gneisenau was the first to be laid down and commissioned. They marked the beginning of German naval rearmament after the Treaty of Versailles. The ships were armed with nine 28 cm (11 in) SK C/34 guns in three triple turrets; plans to replace these with six 38 cm (15 in) SK C/34 guns in twin turrets were never realized.

<span class="mw-page-title-main">Operation Sportpalast</span> German naval raid of World War II

Operation Sportpalast, also known as Operation Nordmeer, was a German naval raid between 6 and 13 March 1942 against two of the Allied Arctic convoys of World War II as they passed through the Norwegian Sea. It was conducted by the battleship Tirpitz, three destroyers and eight submarines. The German ships were unable to locate either of the convoys but sank a merchant vessel that was sailing independently. The Allies attempted to intercept the German force, also without success.

<span class="mw-page-title-main">Operation Tungsten</span> Second World War Royal Navy air raid

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.

Last battle of <i>Bismarck</i> 1941 sinking of a German battleship

The last battle of the German battleship Bismarck took place in the Atlantic Ocean approximately 300 nautical miles west of Brest, France, on 26–27 May 1941 between the German battleship Bismarck and naval and air elements of the British Royal Navy. Although it was a decisive action between capital ships, it has no generally accepted name. It was the culmination of Operation Rheinübung where the attempt of two German ships to disrupt the Atlantic Convoys to the United Kingdom failed with the scuttling of the Bismarck.

<span class="mw-page-title-main">Operation Paravane</span> British air raid on German battleship Tirpitz

Operation Paravane was a British air raid of World War II that inflicted heavy damage on the German battleship Tirpitz, at anchor in Kaafjord in the far north of German-occupied Norway. The attack was conducted on 15 September 1944 by 21 Royal Air Force heavy bombers, which flew from an airfield in the north of the Soviet Union. The battleship was struck by one bomb, and further damaged by several near misses. This damage rendered Tirpitz unfit for combat, and she could not be repaired as it was no longer possible for the Germans to sail her to a major port.

<span class="mw-page-title-main">Operation Obviate</span> Unsuccessful British air raid in World War II

Operation Obviate was an unsuccessful British air raid of World War II which targeted the German battleship Tirpitz. It was conducted by Royal Air Force heavy bombers on 29 October 1944, and sought to destroy the damaged battleship after she moved to a new anchorage near Tromsø in northern Norway.

<span class="mw-page-title-main">Operation Catechism</span> British air raid of World War II

Operation Catechism was a British air raid of World War II that destroyed the German battleship Tirpitz. It was conducted on 12 November 1944 by 29 Royal Air Force heavy bombers that attacked the battleship at its anchorage near the Norwegian city of Tromsø. The ship capsized after being hit by at least two bombs and damaged by the explosions of others, killing between 940 and 1,204 members of the crew; the British suffered no casualties.

<i>Bismarck</i>-class battleship Class of German World War II-era fast battleships

The Bismarck-class was a pair of fast battleships built for Nazi Germany's Kriegsmarine shortly before the outbreak of World War II. The ships were the largest and most powerful warships built for the Kriegsmarine; displacing more than 41,000 metric tons normally, they were armed with a battery of eight 38 cm (15 in) guns and were capable of a top speed of 30 knots. Bismarck was laid-down in July 1936 and completed in September 1940, while the keel of her sister ship, Tirpitz, was laid in October 1936 and work finished in February 1941. The ships were ordered in-response to the French Richelieu-class battleships, themselves laid-down in-response to the Italian Littorio-class battleships. The Bismarck-class was designed with the traditional role of engaging enemy battleships in home waters in mind, though the Oberkommando der Marine envisioned employing the ships as long-range commerce raiders against British shipping in the Atlantic Ocean. As such, their design represented the strategic confusion that dominated German naval construction in the 1930s.

German battleship <i>Scharnhorst</i> Scharnhorst-class battleship of Nazi Germanys Kriegsmarine

Scharnhorst was a German capital ship, alternatively described as a battleship or battlecruiser, of Nazi Germany's Kriegsmarine. She was the lead ship of her class, which included her sister ship Gneisenau. The ship was built at the Kriegsmarinewerft dockyard in Wilhelmshaven; she was laid down on 15 June 1935 and launched a year and four months later on 3 October 1936. Completed in January 1939, the ship was armed with a main battery of nine 28 cm (11 in) C/34 guns in three triple turrets. Plans to replace these weapons with six 38 cm (15 in) SK C/34 guns in twin turrets were never carried out.

German battleship <i>Gneisenau</i> Scharnhorst-class battleship

Gneisenau was a German capital ship, alternatively described as a battleship and battlecruiser, in Nazi Germany's Kriegsmarine. She was the second vessel of her class, which included her sister ship, Scharnhorst. The ship was built at the Deutsche Werke dockyard in Kiel; she was laid down on 6 May 1935 and launched on 8 December 1936. Her outfitting was completed in May 1938: she was armed with a main battery of nine 28 cm (11 in) C/34 guns in three triple turrets. At one point after construction had started, a plan had been approved to replace these weapons with six 38 cm (15 in) SK C/34 guns in twin turrets, but when it was realized that this would involve a lot of redesign, that plan was abandoned, and construction continued with the originally planned lower-calibre guns. The upgrade had been intended to be completed in the winter of 1940–41, but instead, due to the outbreak of World War II, that work was stopped.

<span class="mw-page-title-main">Operation Mascot</span> 1944 British carrier air raid against the German battleship Tirpitz

Operation Mascot was an unsuccessful British carrier air raid conducted against the German battleship Tirpitz at her anchorage in Kaafjord, Norway, on 17 July 1944. The attack was one of a series of strikes against the battleship launched from aircraft carriers between April and August 1944, and was initiated after Allied intelligence determined that the damage inflicted during the Operation Tungsten raid on 3 April had been repaired.

<span class="mw-page-title-main">Operation Goodwood (naval)</span> 1944 series of British air raids against the Tirpitz

Operation Goodwood was a series of British carrier air raids conducted against the German battleship Tirpitz at her anchorage in Kaafjord in occupied Norway during late August 1944. It was the last of several attacks made by the Home Fleet during 1944 which sought to damage or sink Tirpitz and thereby eliminate the threat it posed to Allied shipping. Previous raids on Kaafjord conducted by Fleet Air Arm aircraft had involved only one air attack; in Operation Goodwood several attacks were made in a single week. The Royal Navy hoped that these raids would wear down the formidable German defences.
