Service history and fate
A vital part of the Royal Norwegian Navy, Harald Haarfagre performed ordinary duties until she was considered "unfit for war" in the mid-1930s and disarmed. After the German invasion of Norway, she was seized by the Germans and rebuilt as a floating flak battery under the name Thetis. After the war Harald Haarfagre was used briefly as a floating barracks, and for transporting German POWs, before she was sold for scrapping in 1948.
It was intended to augment the Norwegian Panserskip fleet with the two ships of the Bjørgvin class, ordered in 1912, but after these were compulsorily purchased by the Royal Navy at the outbreak of the First World War, the Tordenskjold class and the slightly newer, two ship, Eidsvold class remained in service the Norwegian navy long after they were obsolete due to a lack of suitable replacements.
Today the name KNM Harald Haarfagre is used on the Royal Norwegian Navy and Royal Norwegian Air Force Basic Training Establishment, located in Madla, Stavanger.
The Royal Norwegian Navy is the branch of the Norwegian Armed Forces responsible for naval operations of Norway. As of 2008, the Royal Norwegian Navy consists of approximately 3,700 personnel and 70 vessels, including 4 heavy frigates, 6 submarines, 14 patrol boats, 4 minesweepers, 4 minehunters, 1 mine detection vessel, 4 support vessels and 2 training vessels. It also includes the Coast Guard.
An ironclad is a steam-propelled warship protected by iron or steel armor plates, constructed from 1859 to the early 1890s. The ironclad was developed as a result of the vulnerability of wooden warships to explosive or incendiary shells. The first ironclad battleship, Gloire, was launched by the French Navy in November 1859 - narrowly pre-empting the British Royal Navy.
The Courageous class consisted of three battlecruisers known as "large light cruisers" built for the Royal Navy during the First World War. The class was nominally designed to support the Baltic Project, a plan by Admiral of the Fleet Lord Fisher that was intended to land troops on the German Baltic Coast. Ships of this class were fast but very lightly armoured, with only a few heavy guns. They were given a shallow draught, in part to allow them to operate in the shallow waters of the Baltic but also reflecting experience gained earlier in the war. To maximize their speed, the Courageous-class battlecruisers were the first capital ships of the Royal Navy to use geared steam turbines and small-tube boilers.
HMS Gorgon and her sister ship Glatton were two monitors originally built as coastal defence ships for the Royal Norwegian Navy, as HNoMS Nidaros and Bjørgvin respectively, by Armstrong Whitworth at Elswick. She was purchased from Norway at the beginning of the First World War, but was not completed until 1918 although she had been launched over three years earlier. She engaged targets in Occupied Flanders for the last several months of the war and fired the last shots of the war against such targets on 15 October 1918. She was used as a target ship after several attempts to sell her had fallen through before being sold for scrap in 1928.
HMS Searcher was a Ruler-class escort carrier of the Royal Navy. Built in Seattle as a Bogue-class, she was transferred to the United Kingdom under Lend-Lease. Launched in 1942 she served until 29 November 1945. She was sold into merchant service and renamed Captain Theo. In 1966, she was renamed again to Oriental Banker and was finally scrapped in Taiwan in 1976.
HNoMS Norge was a coastal defence ship of the Eidsvold-class in the Royal Norwegian Navy. Built by Armstrong Whitworth at Newcastle on Tyne, she was torpedoed and sunk by German destroyers in Narvik harbour on 9 April 1940.
HNoMS Eidsvold was a coastal defence ship and the lead ship of her class, serving in the Royal Norwegian Navy. Built by Armstrong Whitworth at Newcastle on Tyne in 1899, she was obsolete when sunk by German torpedoes in Narvik harbour on 9 April 1940 during the German invasion of Norway.
Coastal defence ships were warships built for the purpose of coastal defence, mostly during the period from 1860 to 1920. They were small, often cruiser-sized warships that sacrificed speed and range for armour and armament. They were usually attractive to nations that either could not afford full-sized battleships or could be satisfied by specially designed shallow-draft vessels capable of littoral operations close to their own shores. The Nordic countries and Thailand found them particularly appropriate for their island-dotted coastal waters. Some vessels had limited blue-water capabilities; others operated in rivers.
The Eidsvold class was a class of coastal defence ships, two of which were built for the Royal Norwegian Navy in 1899 by Armstrong Whitworth. The class consisted of two ships, HNoMS Eidsvold and HNoMS Norge. Locally they were referred to as panserskip.
The Bjørgvin-class coastal battleships were ordered by Norway in 1912 to supplement the older Eidsvold and Tordenskjold-class coastal defence ships. The two ships laid down were compulsorily purchased by the Royal Navy when World War I broke out, and classified as monitors. The British government paid Norway £370,000 as compensation for each ship.
The Tordenskjold class of coastal defence ships was ordered by Norway as part as the general rearmament in the time leading up to the events in 1905 - when Norway broke out of the union with Sweden - the two ships in the class remained the backbone of the Royal Norwegian Navy until they were considered 'unfit for war' in the mid-1930s.
HNoMS Tordenskjold, known locally as Panserskipet Tordenskjold, was a Norwegian coastal defence ship. She, her sister ship, Harald Haarfagre, and the slightly newer Eidsvold class were built as a part of the general rearmament in the time leading up to the events in 1905. Tordenskjold remained an important vessel in the Royal Norwegian Navy until she was considered unfit for war in the mid-1930s.
The Ekaterina II class were a class of four battleships built for the Imperial Russian Navy in the 1880s. They were the first battleships built for the Black Sea Fleet. Their design was highly unusual in having the main guns on three barbettes grouped in a triangle around a central armored redoubt, two side-by-side forward and one on the centerline aft. This was intended to maximize their firepower forward, both when operating in the narrow waters of the Bosphorus and when ramming. Construction was slow because they were the largest warships built until then in the Black Sea, and the shipyards had to be upgraded to handle them.
Spetsai was a Greek ironclad battleship of the Hydra class that served in the Royal Hellenic Navy from 1890 until 1920. She was named after the Saronic Gulf island of Spetses, which played a key role in the war at sea during the Greek War of Independence. Spetsai she was ordered in 1885 in response to a crisis in the Balkans and Ottoman naval expansion. The ship was launched in 1889 and delivered to Greece by 1902. She was armed with a main battery of three 10.8 inches guns and five 5.9 inches guns, and had a top speed of 17 knots.
Psara was a steel-built ironclad warship named for one of the Aegean Sea islands that played a key role in the war at sea during the Greek War of Independence. The final vessel of the Hydra class, she was ordered in 1885 in response to a crisis in the Balkans and Ottoman naval expansion. The ship was launched in 1889 and delivered to Greece by 1902. She was armed with a main battery of three 10.8 in (270 mm) guns and five 5.9 in (150 mm) guns, and had a top speed of 17 kn.
Imperator Nikolai I was a Russian Imperator Aleksandr II-class battleship built for the Baltic Fleet in the late 1880s. She participated in the celebration of the 400th anniversary of the discovery of America in New York City in 1892. She was assigned to the Mediterranean Squadron and visited Toulon in October 1893. She sailed for the Pacific Ocean during the First Sino-Japanese War and remained in the Pacific until late 1896, when she returned to the Mediterranean Squadron and supported Russian interests during the Cretan Revolt. She returned to the Baltic in April 1898 and had a lengthy refit, which replaced all of her machinery, before returning to the Mediterranean in 1901.
The Gorgon-class monitors were a class of monitors in service with the Royal Navy during World War I. Gorgon and her sister ship Glatton were originally built as coastal defence ships for the Royal Norwegian Navy, as HNoMS Nidaros and HNoMS Bjørgvin respectively but requisitioned for British use. Gorgon commissioned first, in June 1918 and bombarded German positions and other targets in Occupied Flanders. She fired the last shots of the war by the Royal Navy into Belgium on 15 October 1918. She was offered for sale after the war, but was used as a target ship when there were no takers. She was sold for scrap in 1928. Glatton was destroyed by a magazine explosion only days after she was completed in September 1918 while in Dover Harbour. She remained a hazard to shipping until the wreck was partially salvaged and the remains moved out of the way during 1925–26.
Giovanni Bausan was a protected cruiser of the Italian Regia Marina that was designed and built by Sir W G Armstrong Mitchell & Co.'s Elswick Works in England in the mid-1880s. The finished ship entered service in May 1885. She was the first ship of this type to be built for the Italian fleet, and she provided the basis for subsequent designs built in Italy, including the Etna class. Giovanni Bausan was intended to serve as a "battleship destroyer", and was armed with a main battery of two 10-inch (254 mm) guns to give her the ability to defeat heavy armor, but design flaws rendered her unfit for this role.
Tordenskjold was a torpedo ram built for the Royal Danish Navy in the early 1880s. The ship was sold for scrap in 1908.
