HSwMS Sölve is one of seven Hildur-class monitors built for the Swedish Navy in the mid-1870s. The ship had an uneventful career and was sold in 1919 for conversion into a barge. She became a museum ship in Gothenburg, Sweden, in 1992.
Faà di Bruno was an Italian monitor built during World War I. Completed in 1917, the ship played a small role in the 11th Battle of the Isonzo later that year. She was decommissioned in 1924, but returned to service as the floating battery GM 194 at the beginning of World War II and was towed to Genoa and where she spent the rest of the war. The ship had her guns disabled when the Royal Navy bombarded Genoa in 1941. GM 194 was captured by the Germans after the Italian Armistice in 1943 and was turned over to the puppet Repubblica Sociale Italiana that they installed afterward. She was scuttled at the end of the war and subsequently scrapped.
The Pará-class monitors were a group of six wooden-hulled ironclad monitors named after Brazilian provinces and built in Brazil for the Imperial Brazilian Navy during the Paraguayan War in the late 1860s. The first three ships finished, Pará, Alagoas and Rio Grande, participated in the Passage of Humaitá in February 1868. Afterwards the remaining ships joined the first three and they all provided fire support for the army for the rest of the war. The ships were split between the newly formed Upper Uruguay and Mato Grosso Flotillas after the war. Alagoas was transferred to Rio de Janeiro in the 1890s and participated in the Fleet Revolt of 1893–94.
The Brazilian monitor Pará was the lead ship of the Pará-class river monitors built for the Brazilian Navy during the Paraguayan War in the late 1860s. Pará participated in the Passagem de Humaitá in February 1868 and provided fire support for the army for the rest of the war. The ship was assigned to the Mato Grosso Flotilla after the war. Pará was disarmed and discarded in 1884.
The Brazilian monitor Rio Grande was the second ship of the Pará-class river monitors built for the Imperial Brazilian Navy during the Paraguayan War in the late 1860s. Rio Grande participated in the Passage of Humaitá on 19 February 1868 and provided fire support for the army for the rest of the war. The ship was assigned to the Upper Uruguay flotilla after the war. Rio Grande was scrapped in 1907.
The Brazilian monitor Alagoas was the third ship of the Pará-class river monitors built for the Imperial Brazilian Navy during the Paraguayan War in the late 1860s. Alagoas participated in the Passage of Humaitá on 19 February 1868 and provided fire support for the army for the rest of the war. The ship was assigned to the Upper Uruguay flotilla after the war. Alagoas was transferred to Rio de Janeiro in the 1890s and participated in the Navy Revolt of 1893–94. The ship was scrapped in 1900.
The Brazilian monitor Piauí was the fourth ship of the Pará-class river monitors built for the Brazilian Navy during the Paraguayan War in the late 1860s. Piauí passed the fortifications at Humaitá in July 1868 and provided fire support for the army for the rest of the war. The ship was assigned to the Mato Grosso Flotilla after the war. Piauí was scrapped in 1893.
The Brazilian monitor Ceará was the fifth ship of the Pará-class river monitors built for the Brazilian Navy during the Paraguayan War in the late 1860s. Ceará arrived in Paraguay in mid-1868 and provided fire support for the army for the rest of the war. The ship was assigned to the Mato Grosso Flotilla after the war. Ceará was scrapped in 1884.
The Brazilian monitor Santa Catharina was the sixth, and last, ship of the Pará-class river monitors built for the Brazilian Navy during the Paraguayan War in the late 1860s. By the time she was completed the war was winding down and she only had one significant engagement against Paraguayan forces in 1869. The ship was assigned to the Mato Grosso Flotilla after the war. Santa Catharina sank at her moorings while under repair in 1882.
The John Ericsson-class monitors were a group of five iron-hulled monitors; four were built for the Royal Swedish Navy and one for the Royal Norwegian Navy in the mid to late 1860s. They were designed under the supervision of the Swedish-born inventor, John Ericsson, and built in Sweden. Generally, the monitors were kept in reserve for the majority of the year and were only commissioned for several during the year. The ships made one foreign visit to Russia in 1867 but remained in Swedish or Norwegian waters for the rest of their careers. Two of the monitors, Thordon and Mjølner, ran aground, but were salvaged and repaired. Most of the monitors were reconstructed between 1892 and 1905 with more modern guns, but one was scrapped instead as it was not thought cost-effective to rebuild such an old ship. The surviving ships were mobilized during World War I and sold for scrap afterwards.
HSwMS John Ericsson was the lead ship of the John Ericsson-class monitors built for the Royal Swedish Navy in the mid-1860s. She was designed under the supervision of the Swedish-born inventor, John Ericsson, and built in Sweden. John Ericsson made one foreign visit to Russia in 1867, but remained in Swedish or Norwegian waters for the rest of her career. The ship was reconstructed between 1892 and 1895, but generally remained in reserve. She was mobilized during World War I and sold in 1919 for conversion to a barge.
HSwMS Thordön was the second ship of the John Ericsson-class monitors, built for the Royal Swedish Navy in the mid-1860s. She was designed under the supervision of the Swedish-born inventor, John Ericsson, and built in Sweden. Thordön made one foreign visit to Russia in 1867, but remained in Swedish or Norwegian waters for the rest of her career. The ship was reconstructed between 1903 and 1905, but generally remained in reserve. She was mobilized during World War I, and sold in 1922 for conversion to a barge.
HSwMS Tirfing was the third ship of the John Ericsson-class monitors built for the Royal Swedish Navy in the mid-1860s. She was designed under the supervision of the Swedish-born inventor John Ericsson, and built in Sweden. Tirfing made one foreign visit to Russia in 1867, but remained in Swedish or Norwegian waters for the rest of her career. The ship was reconstructed between 1903 and 1905, but generally remained in reserve. She was mobilized during World War I and sold in 1922 for conversion to a barge.
HSwMS Loke was the fourth, and last, ship of the John Ericsson-class monitors built for the Royal Swedish Navy in the late-1860s. Completed in 1871 she only made seven short cruises before she was permanently placed in reserve in late 1880. Funds were requested to reconstruct her in line with the other monitors, but were denied. She was listed for sale in 1908, but nothing is known of her fate.
HNoMS Mjølner, named after the hammer of the god Thor, was the fourth of five ships of the John Ericsson-class monitors built for the Royal Swedish Navy and the Royal Norwegian Navy in the mid-1860s. Influenced by the use of ironclads during the American Civil War, the design was based on that of USS Monitor. They were designed under the supervision of the Swedish-born inventor John Ericsson—coincidentally designer of Monitor—and built in Sweden. Mjølner was delivered in 1868. She ran aground the following year, without serious damage, and reconstructed in 1897 with later breech-loading guns. Mjølner was sold for scrap in 1909.
HSwMS Folke was the last of the seven Hildur-class monitors built for the Swedish Navy in the mid-1870s. Unlike her sisters, her gun turret was fixed to the rear. The ship was placed in reserve in 1919 and ultimately sold in 1942.
HSwMS Sköld was a small river monitor built for the Swedish Royal Skerry Artillery in the late 1860s. She was equipped with a dual propulsion system, both hand and steam-driven, although the hand-driven portion was removed early in the ship's career due to complaints from the crew. The ship was put into reserve in 1890 and used as a gunnery target in 1907.
HNLMS Guinea was an Buffel-class monitor built for the Royal Netherlands Navy in the early 1870s. Rearmed in 1887 with more modern ordnance, she was sold for scrap in 1897.
The Hildur-class monitors consisted of seven monitors built for the Swedish Navy in the 1870s. They were sold in 1919 and most were converted into fuel oil barges. One such ship, HSwMS Sölve, has been converted into a museum ship.
HSwMS Berserk was one of seven Hildur-class monitors monitors built for the Swedish Navy in the mid-1870s. The ship had an uneventful career and was sold in 1919 for conversion into a fuel oil barge.
