In naval terminology, a destroyer is a fast, maneuverable, long-endurance warship intended to escort larger vessels in a fleet, convoy, or battle group and defend them against powerful short-range attackers. They were originally developed in 1885 by Fernando Villaamil for the Spanish Navy as a defense against torpedo boats, and by the time of the Russo-Japanese War in 1904, these "torpedo boat destroyers" (TBDs) were "large, swift, and powerfully armed torpedo boats designed to destroy other torpedo boats". Although the term "destroyer" had been used interchangeably with "TBD" and "torpedo boat destroyer" by navies since 1892, the term "torpedo boat destroyer" had been generally shortened to simply "destroyer" by nearly all navies by the First World War.
A torpedo boat is a relatively small and fast naval ship designed to carry torpedoes into battle. The first designs were steam-powered craft dedicated to ramming enemy ships with explosive spar torpedoes. Later evolutions launched variants of self-propelled Whitehead torpedoes.
A gunboat is a naval watercraft designed for the express purpose of carrying one or more guns to bombard coastal targets, as opposed to those military craft designed for naval warfare, or for ferrying troops or supplies.
The motor gun boat (MGB) was a small, high-speed British military vessel of the Second World War, which was armed with a mix of guns, in contrast to the physically similar motor torpedo boat (MTB), whose main offensive weapon were torpedoes. The small size of the MGBs, and their high speed, made them difficult targets for German E-boats, though, like their opponents, they were limited by heavy weather, because they did not provide a stable-enough platform to aim the guns. The large number of guns meant the crew was relatively large, numbering as high as thirty men on the largest boats.
In late 19th-century naval terminology, torpedo gunboats were a form of gunboat armed with torpedoes and designed for hunting and destroying smaller torpedo boats. By the end of the 1890s torpedo gunboats were superseded by their more successful contemporaries, the torpedo boat destroyers.
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 Sleipner was a 1. class gunboat built for the Royal Norwegian Navy. Like all other Norwegian gunships of her era, she carried a heavy armament on a diminutive hull. The vessel was built at the Naval Yard at Horten, and had yard number 56.
At the outbreak of the Second World War Nazi Germany's Kriegsmarine had 21 destroyers in service, while another one was just being completed. These 22 vessels – comprising 3 classes – had all been built in the 1930s, making them modern vessels. Including that final pre-war vessel, a further 19 were brought into service during the war and more were captured from opposing navies, including the Italian Navy after the Italian Armistice with the Allies in 1943.
HNoMS Viking was a 1. class gunboat built for the Royal Norwegian Navy. Like the other Norwegian gunboats of her era, she carried a heavy armament on a diminutive hull. The vessel was built at the Naval Yard at Horten, and had yard number 72.
HNoMS Frithjof was a 1. class gunboat (built for the Royal Norwegian Navy. Like the other Norwegian gunboats of her era, she carried a heavy armament on a diminutive hull. The vessel was built at the Naval Yard at Horten, and had yard number 76.
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.
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.
Steam gun boats (SGBs) were small Royal Navy vessels built from 1940 to 1942 for Coastal Forces during the Second World War. The class consisted of nine steam-powered torpedo boats.
HMS Rattlesnake was a unique design of torpedo gunboat of the Royal Navy. A result of the Russian war scare of 1885, she was designed by Nathaniel Barnaby that year and built by Laird Brothers, of Birkenhead. Quickly made obsolete by the new torpedo boat destroyers, she became an experimental submarine target ship in 1906, and was sold in 1910.
Flat-iron gunboats were a number of classes of coastal gunboats generally characterised by small size, low freeboard, the absence of masts, and the mounting of a single non-traversing large gun, aimed by pointing the vessel. They acquired their nickname from the physical similarity with the flat iron used for ironing clothes during the 19th century.
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.
