HNoMS Tor was a Sleipner class destroyer of the Royal Norwegian Navy that was launched in September 1939. She was under outfitting and testing when Nazi Germany invaded Norway on 9 April 1940. Although scuttled by Norwegian naval personnel to prevent her from being captured by the invading forces, she was soon salvaged by the Germans and put into service with the Kriegsmarine. Under the name Tiger she served out the war as an escort and training vessel, being recovered by the Norwegians in Denmark after the German capitulation in 1945. After the war she was converted to a frigate and served until 1959.


As part of the Norwegian rearmament scheme in the last years leading up to the Second World War, the Royal Norwegian Navy began building a series of new destroyers. The six ships of the Sleipner class were larger than the preceding First World War vintage Draug class vessels. At some 735 tons the Sleipner class ships were still much smaller than the destroyers of the major navies of the time. The Royal Norwegian Navy had requested 1,000 ton destroyers, but financial constraints led to the 735-ton Sleipner class being constructed as a compromise. The Sleipner class design focussed on anti-surface and anti-aircraft artillery, and modern anti-submarine equipment. The ships did however suffer from insufficient range and seaworthiness.[4]

The construction of Tor was financed through the extraordinary appropriations to the Norwegian Armed Forces following the outbreak of the Second World War. The funds were intended to improve the armed forces' ability to protect Norwegian neutrality against violations by the warring parties. While all five of her sister ships were constructed at the Royal Norwegian Navy's main naval yard at Karljohansvern in Horten, Tor was built at Fredrikstad Mekaniske Verksted in Fredrikstad. Her keel was laid in November 1938. The penultimate ship of the Sleipner class, she was launched on 7 September 1939.[4][5][6] The successful launch of Tor at Fredrikstad Mekaniske Verksted led member of parliament from the Conservative Party, naval captain Trygve Sverdrup, in a closed meeting of the Parliament of Norway on 11 March 1940, to argue for further Sleipner class ships to be rapidly constructed at the shipyard in order to improve the numbers of the Royal Norwegian Navy.[7][8]

Second World War

German invasion and scuttling

By the time of the 9 April 1940 German invasion of Norway, Tor had received her crew and begun her trials and shakedown cruises. She had however not yet had any of her armament installed, and was still in the process of fitting out. When it was reported on 9 April that German forces were approaching Fredrikstad, the commander, Captain Ewald Røren, ordered that she was to be scuttled at the shipyard, rather than to be abandoned intact to the advancing Germans.[9][10][11][11][12][13][14][15][Note 1][Note 2] The crew of the Tor made their way inland, joining the Norwegian 1st Division in Østfold and eventually following it into internment in neutral Sweden.[10] The 1st Division's retreat across the border occurred on 14 April 1940, after confused fighting beginning on 12 April.[19]

German service


After their capture of Fredrikstad, the Germans immediately began work on salvaging the scuttled Norwegian warship. On 16 April, a week after her scuttling, Tor was raised from the harbour. Six days later, on 22 April, the Germans moved her to Drammen for repairs and fitting out.[20] The work on Tor, and her sister ship Balder, was completed during the summer of 1940 at Karljohansvern naval yard in Horten. The completion of the two destroyers was the first work carried out by the state-owned Norwegian naval yard for the German occupants during the Second World War.[21][22] Tor had yard number 128 at Karljohansvern.[22]

As Tiger

On 13 June 1940 the Germans commissioned Tor into the Kriegsmarine, renaming her Tiger, and re-designating her as a torpedo boat.[3][Note 3] In German service Tiger was made part of the 7th Torpedo Boat Flotilla; initially carrying out escort duties in the Skagerrak and Kattegat.[20] The fellow captured Norwegian Sleipner class destroyers Gyller (Löwe), Odin (Panther) and Balder (Leopard) also formed part of the same flotilla.[24] The first German commander of Tor was Kapitänleutnant Herbert Juttner, who commanded her until relieved in June 1941 by Oberleutnant zur See Friedrich Nose.[25][26]

From July to December 1940 Tiger functioned as a training ship with the 7th Torpedo Boat Flotilla. When that unit was disbanded she was transferred to the 27th U-boat Flotilla in Gotenhafen as a torpedo recovery vessel. Tiger spent the rest of the war with the 27th U-boat Flotilla, being recovered in Korsør, Denmark in May 1945 and returned to the Royal Norwegian Navy.[20][27]

Post-war service

After she rejoined the Royal Norwegian Navy Tor was given her old name back, and on 19 September 1946 was allocated the pennant number L.04.[28] In the force lists provided to the Norwegian Parliament in 1946, Tor, her three sister ships, two Hunt class ships and a vessel still under construction at Karljohansvern were listed as escort destroyers.[29] In 1948 Tor and the four other Sleipner class vessels that had survived the war, were rebuilt as frigates.[28] During the 1950s Tor was issued with the NATO pennant number F.303.[20] In 1959 Tor and her surviving sister ships were all written off and sold for scrapping.[9]


  1. Despite the reports, Fredrikstad was not seized by the Germans for several days following 9 April invasion. The town and surrounding areas were bombed by 15 Heinkel He 111 bombers on 11 April.[16]
  2. Ewald Røren had previously commanded the earlier Sleipner class destroyer Sleipner. Captain Røren was deported to Germany as a prisoner of war in 1942. Inspired by the Oxford Movement, he acted as a lay preacher for the Norwegian prisoners of war while imprisoned.[11][17][18]
  3. The Kriegsmarine had previously operated a Raubtier class torpedo boat named Tiger, but this vessel had been lost in a collision with the destroyer Max Schultz on 25 August 1939, shortly before the outbreak of the Second World War.[23]
