Fridtjof Nansen was the first ship in the Norwegian armed forces to be built specially to perform coast guard and fishery protection duties in the Arctic. She saw service in the Second World War with the Royal Norwegian Navy until she ran aground on an unmarked shallow at Jan Mayen in November 1940.
The Draug class was the first multi-vessel class of destroyers built for the Royal Norwegian Navy in the early 20th century and the first destroyers constructed for the Royal Norwegian Navy since Valkyrjen, which was commissioned on 17 May 1896. The class comprised three ships, Draug, Troll and Garm. All three were built at the naval shipyard at Horten. The Draug class were the last Norwegian-constructed destroyers until the Ålesund class was laid down in 1939. The Draug class saw service until the 1940s. In 1940, Garm was sunk while the other two remained in service until sold and broken up for scrap.
HNoMS Draug was the lead ship of the three-ship Draug class of destroyers built for the Royal Norwegian Navy in the years 1908–1913. The four-stacked destroyer was kept in service long after she was obsolete, and took part in the defence of Norway during the German invasion in 1940.
HNoMS Garm was the third destroyer built for the Royal Norwegian Navy, and was a Draug class destroyer. Garm was constructed several years after her two sister ships, but to the same plans. She was built at the naval shipyard in Horten, with yard number 107.
The Sleipner class was a class of six destroyers built for the Royal Norwegian Navy from 1936 until the German invasion in 1940. The design was considered advanced for its time, and it was the first class of vessels for the Norwegian Navy that used aluminium in the construction of the bridge, the mast and the outer funnel. Extra strength special steel was used in the construction of the hull. Unlike the earlier Draug class the Sleipner class had comparatively good capabilities in both main guns, anti-aircraft artillery and anti-submarine weapons. The class was named after Sleipnir, the eight-legged horse of Odin.
The HNoMS Gor was a Gor-class Rendel gunboat built for the Royal Norwegian Navy at Karljohansvern Naval Yard in Horten in 1884. She was one of a class of two gunboats - the other ship in her class being Tyr. The Gor and Tyr can be seen as improved Vale-class gunboats.
HNoMS Tyr was a Gor-class Rendel gunboat built for the Royal Norwegian Navy at Karljohansverns Verft Naval Yard in Horten. She was laid down in 1884 and launched in 1887 with build number 67. Tyr was one of a class of two gunboats - the other ship in her class being HNoMS Gor. Gor and Tyr can be seen as improved Vale-class gunboats, of 290 tons instead of the 250 tons standard for that class.
The minelayer HNoMS Olav Tryggvason was built by the naval shipyard at Horten in the early 1930s and had build number 119. She served in the Royal Norwegian Navy until captured by the Germans in 1940. The Germans renamed her first Albatros II, and a few days later Brummer. She was wrecked in a British bombing raid in northern Germany in April 1945.
HNoMS Kjell was the final ship of twenty-seven 2nd class torpedo boats built for the Royal Norwegian Navy, launched at the Royal Norwegian Navy's shipyard in Horten on 12 March 1912 with build number 106. Kjell saw more than 32 years of service, the first 28 years in the Royal Norwegian Navy during the First World War and in the interwar period, the last four in the Kriegsmarine, having been captured in the first days of the 1940 Norwegian campaign. After being rebuilt as a minesweeper by the Germans, she was sunk by Royal Air Force de Havilland Mosquito fighter bombers on 28 September 1944. Divers rediscovered the shipwreck in 2006.
HNoMS Æger was a Sleipner-class destroyer launched at Karljohansvern naval shipyard in Horten in 1936. The Sleipner class was part of a Norwegian rearmament scheme started as war became ever more likely in the 1930s. When the Germans invaded Norway on 9 April 1940, Æger intercepted and sank the clandestine German supply ship Roda. She was shortly afterwards attacked and sunk by German bombers, claiming two of the attacking aircraft with her anti-aircraft armament before being taken out of action by a heavy bomb.
HNoMS Sleipner was a destroyer commissioned into the Royal Norwegian Navy in 1936. The lead ship of the Sleipner class, she gained near-legendary status in Norway by enduring over two weeks of intense air attack by Luftwaffe bombers following the 9 April 1940 invasion of Norway. After the resistance in South Norway started unravelling she made her way over the North Sea to continue the fight against the Germans from exile. After serving as a convoy escort along the coast of the United Kingdom, she was decommissioned in 1944. She was recommissioned in 1948 after being converted to a frigate. Along with her surviving sister ships she was sold for scrapping in 1959.
HNoMS Gyller was a Sleipner-class destroyer commissioned into the Royal Norwegian Navy in 1938. Along with the other Sleipner-class vessels in commission at that time, she took part in protecting Norwegian neutrality during the Second World War. After initially serving in the far north during the Finno-Soviet Winter War, she was redeployed to Southern Norway, escorting ships through Norwegian territorial waters. When the Germans invaded Norway on 9 April 1940, she was docked at Kristiansand. After taking part in the defence of the port city, she was captured intact by the invading Germans. Renamed Löwe, she sailed with Nazi Germany's Kriegsmarine for the duration of the war.
HNoMS Odin was a Sleipner-class destroyer that entered service with the Royal Norwegian Navy in 1939. She and the other Sleipner-class vessels were built as part of a Norwegian rearmament scheme in the last years leading up to the Second World War. In 1940, she had taken part in protecting Norwegian neutrality, before being caught in the German invasion of Norway on 9 April 1940. After fighting the invasion forces at Kristiansand, she was captured and pressed into Kriegsmarine service for the duration of the war. After the end of the war, she was returned to Norway. In 1948, she and her surviving sister ships were converted to frigates and remained in service until sold for scrapping in 1959.
HNoMS Rauma was an Otra-class minesweeper built in 1939 for the Royal Norwegian Navy. Captured by the Germans during the 1940 invasion of Norway and renamed Kamerun, she was returned to the Norwegians after the end of the Second World War and recommissioned in 1947. Rauma remained in service until being sold for scrapping in 1963.
HNoMS Otra was an Otra-class minesweeper built in 1939 for the Royal Norwegian Navy. Captured by the Germans during the 1940 invasion of Norway and renamed Togo, she was returned to the Norwegians in 1946. Otra remained in service until being sold for scrapping in 1963.
The last of the Trygg class of Royal Norwegian Navy torpedo boats was HNoMS Stegg. Her sister ships were Trygg and Snøgg. The Trygg class vessels were the only additions to the Norwegian fleet of torpedo boats between the First and the Second World Wars. At the outbreak of the Second World War the Trygg class was mobilised together with eight 2. class and six 1. class torpedo boats.
HNoMS Nordkapp was the lead ship of the Nordkapp class of fishery protection vessels. She was launched 18 August 1937 at Horten naval shipyard, with yard number 123. She had one sister ship, HNoMS Senja. Nordkapp was named after the North Cape in Finnmark. As was typical of her class, Nordkapp was very unstable in rough seas and was viewed from the beginning as a second-rate vessel. Nordkapp sailed throughout the Second World War and saw service in several theatres.
The Trygg class was the third and last class of torpedo boats to be built for the Royal Norwegian Navy. The three Trygg ships were constructed from 1919 to 1921 at Moss Verft in Moss (Trygg) and Horten naval yard.
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.
HNoMS Brand was a 1.-class torpedo boat constructed in 1898. She served the Royal Norwegian Navy for more than four decades, including neutrality protection duties during the First World War. Having once again been employed on neutrality protection duty at the outbreak of the Second World War, Brand was captured by the Germans during their invasion of Norway in April 1940.
