The Battle class were a class of destroyers of the British Royal Navy (RN) and Royal Australian Navy (RAN), named after naval or other battles fought by British or English forces. Built in three groups, the first group were ordered under the 1942 naval estimates. A modified second and third group, together with two ships of an extended design were planned for the 1943 and 1944 estimates. Most of these ships were cancelled when it became apparent that the war was being won and the ships would not be required, although two ships of the third group, ordered for the RAN, were not cancelled and were subsequently completed in Australia.
The Daring class was a class of eleven destroyers built for the Royal Navy (RN) and Royal Australian Navy (RAN). Constructed after World War II, and entering service during the 1950s, eight ships were constructed for the RN, and three ships for the RAN. Two of the RN destroyers were subsequently sold to and served in the Peruvian Navy (MGP). A further eight ships were planned for the RN but were cancelled before construction commenced, while a fourth RAN vessel was begun but was cancelled before launch and broken up on the slipway.
The Weapon class was a class of destroyers built for the British Royal Navy towards the end of World War II. They were the smaller counterpart to the Battle class and were the first new destroyer designs for the Royal Navy since the Second World War Emergency Programme. 20 ships were planned, of which only 13 were laid down and 7 were launched, but the cessation of hostilities resulted in only 4 being completed for service. Two of the ships had been previously ordered as part of the planned C class, or 15th Emergency flotilla, of 1944, but the orders were changed to the new design.
The Smith-class destroyers were the first ocean-going torpedo-boat destroyers in the United States Navy, and the first to be driven by steam turbines instead of the reciprocating engines fitted in the sixteen earlier and much smaller torpedo-boat destroyers ordered under the Act of 4 May 1898. Flusser and Reid are sometimes considered to be Flusser-class ships. Also, since Flusser was completed first, some period documentation refers to the entire class as Flussers.
The Caldwell class was a class of six "flush deck" United States Navy destroyers built during World War I and shortly after. Four served as convoy escorts in the Atlantic; the other two were completed too late for wartime service. Two were scrapped during the 1930s, but four survived to serve throughout World War II, three of these in service with the Royal Navy under the Destroyers for Bases Agreement and the fourth as a high speed transport.
The River-class destroyer was a class of torpedo boat destroyer built for the Royal Navy in the first few years of the 20th century, and which saw extensive service in World War I. These 37 vessels were all constructed to disparate builders' designs, just like the preceding classes.
The Spica-class was a class of torpedo boats of the Regia Marina during World War II. These ships were built as a result of a clause in the Washington Naval Treaty, which stated that ships with a tonnage of less than 600 could be built in unlimited numbers. Thirty-two ships were built between 1934 and 1937, thirty of which entered service with Italy.
The first R class were a class of 62 destroyers built between 1916 and 1917 for the Royal Navy. They were an improvement, specifically in the area of fuel economy, of the earlier Admiralty M-class destroyers. The most important difference was that the Admiralty R class had two shafts and geared turbines, compared with the three shafts and direct turbines of the Admiralty M class, but in appearance the R class could be distinguished from its predecessors by having the after 4-inch gun mounted in a bandstand. The Admiralty ordered the first two of this class of ships in May 1915. Another seventeen were ordered in July 1915, a further eight in December 1915, and a final twenty-three in March 1916.
The Folgore class were a group of four destroyers built for the Regia Marina in the 1930s. None of the ships survived World War II.
Aetos was an Aetos-class destroyer which served in the Royal Hellenic Navy from 1912–1945.
Dubrovnik was a flotilla leader built for the Royal Yugoslav Navy by Yarrow Shipbuilders in Glasgow in 1930 and 1931. She was one of the largest destroyers of her time. Resembling contemporary British designs, Dubrovnik was a fast ship with a main armament of four Czechoslovak-built Škoda 140 mm (5.5 in) guns in single mounts. She was intended to be the first of three flotilla leaders built for Yugoslavia, but was the only one completed. During her service with the Royal Yugoslav Navy, Dubrovnik undertook several peacetime cruises through the Mediterranean, the Turkish Straits and the Black Sea. In October 1934, she conveyed King Alexander to France for a state visit, and carried his body back to Yugoslavia following his assassination in Marseille.
The Aetos class were four destroyers were originally constructed for the Argentine Navy as the San Luis class. In Greek they are known as the Thiria class, after the ships' names. They were purchased by the Royal Hellenic Navy in October 1912 when the Greek government expanded its navy after losing the Greco-Turkish War of 1897 and in anticipation of the Balkan Wars. In December 1916, during World War I, three of the destroyers were seized by France and served in the French Navy until 1918, all except Panthir. They were returned to Greece in 1918. In 1924–1925, they were extensively rebuilt and continued in service into World War II, where they fought with the Allies. Leon was sunk by German aircraft at Suda Bay, Crete. The other three destroyers survived the war and were used as station ships during the Greek Civil War. They were discarded in 1946.
The Hatsuharu-class destroyers were a class of Imperial Japanese Navy destroyers in the service before and during World War II. The final two vessels in the class, completed after modifications to the design, are sometimes considered a separate "Ariake class".
The Nembo class was a class of destroyer of the Italian Regia Marina. Six destroyers were built by the Pattison shipyard of Naples between 1899 and 1905, to a design based on the contemporary destroyers of the British shipyard Thornycroft. They were active in the Italo-Turkish War and in the First World War, where three were lost.
The French destroyer Cassard was one of six Vauquelin-class destroyers built for the French Navy during the 1930s. The ship entered service in 1933 and spent most of her career in the Mediterranean. During the Spanish Civil War of 1936–1939, she was one of the ships that helped to enforce the non-intervention agreement. When France declared war on Germany in September 1939, all of the Vauquelins were assigned to the High Sea Forces which was tasked to escort French convoys and support the other commands as needed. Cassard was briefly deployed to search for German commerce raiders and blockade runners in late 1939 and early 1940, but returned to the Mediterranean in time to participate in Operation Vado, a bombardment of Italian coastal facilities after Italy entered the war in June.
Tartu was one of six Vauquelin-class destroyers built for the French Navy during the 1930s. The ship entered service in 1933 and spent most of her career in the Mediterranean. During the Spanish Civil War of 1936–1939, she was one of the ships that helped to enforce the non-intervention agreement. When France declared war on Germany in September 1939, all of the Vauquelins were assigned to the High Sea Forces which was tasked to escort French convoys and support the other commands as needed. Tartu was briefly deployed to Scotland in early 1940 to support the Allied forces in the Norwegian Campaign, but returned to the Mediterranean in time to participate in Operation Vado, a bombardment of Italian coastal facilities after Italy entered the war in June.
Chevalier Paul was one of six Vauquelin-class large destroyers built for the French Navy during the 1930s. The ship entered service in 1934 and spent most of her career in the Mediterranean. During the Spanish Civil War of 1936–1939, she was one of the ships that helped to enforce the non-intervention agreement. When France declared war on Germany in September 1939, all of the Vauquelins were assigned to the High Sea Forces which was tasked to escort French convoys and support the other commands as needed. Chevalier Paul was briefly deployed to Scotland in early 1940 to support the Allied forces in the Norwegian Campaign, but returned to the Mediterranean in time to participate in Operation Vado, a bombardment of Italian coastal facilities after Italy entered the war in June.
The B 97 class was a class of eight destroyers built for and operated by the Imperial German Navy during the First World War. They served throughout the war, with one being lost in 1915, five being scuttled at Scapa Flow in 1919 and one being transferred to Italy, where it remained in use until 1939.
HMS Tobago was a Thornycroft S-class destroyer which served with the Royal Navy during the Greco-Turkish War. Launched by Thornycroft on 15 July 1918, the vessel followed a design typical of the yard by being faster than the majority of the class, and also had better seakeeping properties thanks to a raised forecastle. The destroyer operated as part of the Grand Fleet for the last few weeks of the First World War, and, after the Armistice, joined the Mediterranean Fleet based in Malta. While serving in off the coast of Turkey, the ship hit a mine on 15 July 1920, exactly two years after being launched. Despite the relative youth of the vessel, the damage was deemed irrepairable and so Tobago returned to Malta and was sold for scrap on 9 February 1922.
HMS Seraph was an S-class destroyer, which served with the Royal Navy during the Russian Civil War. The S class were a development of the previous R class, with minor differences, constructed at the end of the First World War. Seraph had a career as an evacuation vessel more than as a warship. Launched in 1918 by Denny, Seraph was originally destined for the Grand Fleet but, after the Armistice, the destroyer transferred to the Mediterranean Fleet based at Malta. The destroyer was sent into the Black Sea to support the White Russian forces in their fight against the Communists. The role involved supporting the movement of troops rather than firing at the enemy. Ultimately, the Communists won and Seraph helped the evacuation of White Russian troops from Crimea, returning to Malta in 1921. The destroyer was then stationed in the Eastern Mediterranean in 1923 in response to the tensions in Turkey. In 1927, the ship was sent to Hong Kong to serve under the Commander-in-Chief, China. In 1929, the vessel was once again called to evacuate, this time Christian missionaries from the Chinese Red Army. Once again, the evacuation took place without bloodshed. With the introduction of more modern destroyers, the Royal Navy started retiring the S class and, in 1934, Seraph was sold to be broken up.
