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.
Augustus Willington Shelton Agar, was a Royal Navy officer in both the First and the Second World Wars. He was a recipient of the Victoria Cross, the highest award for gallantry in the face of the enemy that can be awarded to British and Commonwealth forces, for sinking a Soviet cruiser during the Russian Civil War.
A motor torpedo boat is a fast torpedo boat, especially of the mid 20th century. The motor in the designation originally referred to their use of petrol engines, typically marinised aircraft engines or their derivatives, which distinguished them from other naval craft of the era, including other torpedo boats, that used steam turbines or reciprocating steam engines. Later, diesel-powered torpedo boats appeared, in turn or retroactively referred to as "motor torpedo boats" for their internal combustion engines, as distinct from steam powered reciprocating or turbine propulsion.
HM Coastal Motor Boat 4 is the torpedo boat used when Lieutenant Augustus Agar earned a Victoria Cross for carrying out a raid on Soviet warships in Kronstadt and sinking the cruiser Oleg.
The motor gunboat (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.
The Zeebrugge Raid on 23 April 1918, was an attempt by the Royal Navy to block the Belgian port of Bruges-Zeebrugge. The British intended to sink obsolete ships in the canal entrance, to prevent German vessels from leaving port. The port was used by the Imperial German Navy as a base for U-boats and light shipping, which were a threat to Allied control of the English Channel and southern North Sea. Several attempts to close the Flanders ports by bombardment failed and Operation Hush, a 1917 plan to advance up the coast, proved abortive. As ship losses to U-boats increased, finding a way to close the ports became urgent and the Admiralty became more willing to consider a raid.
A fast attack craft (FAC) is a small, fast, agile, offensive, often affordable warship armed with anti-ship missiles, gun or torpedoes. FACs are usually operated in close proximity to land as they lack both the seakeeping and all-round defensive capabilities to survive in blue water. The size of the vessel also limits the fuel, stores and water supplies. In size they are usually between 50–800 tonnes and can reach speeds of 25–50 knots (46–93 km/h).
Vosper & Company, often referred to simply as Vospers, was a British shipbuilding company based in Portsmouth, England.
The British campaign in the Baltic 1918–1919 was a part of the Allied intervention in the Russian Civil War. The codename of the Royal Navy campaign was Operation Red Trek. The intervention played a key role in enabling the establishment of the independent states of Estonia and Latvia. It failed to secure the control of Petrograd by White Russian forces, which was one of the main goals of the campaign.
Coastal Forces was a division of the Royal Navy initially established during World War I, and then again in World War II under the command of Rear-Admiral, Coastal Forces. It remained active until the last minesweepers to wear the "HM Coastal Forces" cap tally were taken out of reserve in 1968. The division received more gallantry awards than any other branch of the Royal Navy during that period.
The Royal Navy, commonly the Royal Yugoslav Navy, was the naval warfare service branch of the Kingdom of Yugoslavia. It was brought into existence in 1921, and initially consisted of a few former Austro-Hungarian Navy vessels surrendered at the conclusion of World War I and transferred to the new nation state under the terms of the Treaty of Saint-Germain-en-Laye. The only modern sea-going warships transferred to the new state were twelve steam-powered torpedo boats, although it did receive four capable river monitors for use on the Danube and other large rivers. Significant new acquisitions began in 1926 with a former German light cruiser, followed by the commissioning of two motor torpedo boats (MTBs) and a small submarine flotilla over the next few years. When the name of the state was changed to Yugoslavia in 1929, the name of its navy was changed to reflect this. In the late 1920s, several of the original vessels were discarded.
The Uskok class was a class of two motor torpedo boats built for the Royal Yugoslav Navy during the late 1920s. Named Uskok and Četnik, the boats were built by the Thornycroft Company based on their existing class of 17-metre-long (55 ft) Coastal Motor Boats, but were almost 1.5 metres (5 ft) longer. As their main armament they were equipped with cradles that carried two British-designed 456-millimetre (18 in) torpedoes, were fitted with hydrophones, and could carry depth charges instead of torpedoes if used in an anti-submarine role. The boats were lightly-built using mahogany, powered by two petrol engines, but lacked transverse bulkheads within the hull to mitigate leaks.
HMS Teazer was an R-class destroyer which served with the Royal Navy during World War I. The destroyer was launched in April 1917 and, on trial, proved to be one of the fastest afloat, exceeding 40 knots. Attached to the Harwich Force, the ship supported the monitors Erebus, Terror and Marshal Soult in the bombardment of Zeebrugge in May 1918 and one of the final sorties of the war in the October following. The destroyer also took part in operations off the coast of Heligoland with a flying boat on a lighter, although the aircraft failed to take off. After the war, Teazer was kept in reserve until being sold to be broken up in 1931 following the signing of the London Naval Treaty that limited total destroyer tonnage.
Captain Russell Hamilton McBean DSO DSC was an officer in the Royal Navy and was one of the men who took part in the Raid on Kronstadt in August 1919.
Gavriil was an Orfey-class destroyer of the Russian Imperial Navy. The destroyer was built by the Russo-Baltic Yard at Reval, launching on 5 January 1915 and completing in October 1916. She served with the Baltic Fleet during the remainder of the First World War, and after the October Revolution joined the Bolshevik Red Fleet. She was active during the Russian Civil War, taking part in several engagements against British ships during the British campaign in the Baltic, and was sunk by a mine on 21 October 1919.
HMS Spenser was a Thornycroft type flotilla leader of the British Royal Navy. She was built by J I Thornycroft from 1916 to 1917 as the lead ship of her class, launching in September 1917 and completing in December that year.
HMS Melpomene was a Medea-class destroyer of the British Royal Navy. She was one of four destroyers, of similar design to the British M-class ordered by Greece in June 1914, which the British purchased during construction owing to the outbreak of the First World War.
Unmanned Aerial Vehicles (UAVs) include both autonomous drones and remotely piloted vehicles (RPVs). The UAVs used in World War I were RPVs. Soon after its re-purposing from the Army Balloon Factory to the Royal Aircraft Factory in 1912, designers at this Farnborough base turned their thoughts to flying an unmanned aircraft. During the First World War this pioneering work resulted in trials of remotely controlled aircraft for the Royal Flying Corps and unmanned boats for the Royal Navy that were controlled from 'mother' aircraft. By the end of the war in 1918 Britain had successfully flown and controlled a drone aircraft and a number of fast unmanned motor boats operating in close flotilla formation had been individually controlled by radio from operators flying in "mother" aircraft. This work then continued in the interwar years.
HMS Stork was an R-class destroyer that served in the Royal Navy during the First World War. The R-class were an improvement on the previous M-class with geared steam turbines to improve efficiency. Launched by Hawthorn Leslie at Hebburn in 1917, Stork joined the Harwich Force. The destroyer saw service escorting convoys in the English Channel and encountered both German submarines and torpedo boats, but did not record any hits on the enemy. The vessel also supported attacks on German forces on the coast of Western Europe by Coastal Motor Boats, flying boats and monitors, including the Zeebrugge Raid of 1918.
The raid on Kronstadt was an attack by Royal Navy coastal motor boats (CMBs) and Royal Air Force aircraft on the Bolshevik Baltic Fleet at its home base on 18 August 1919. After the Allied intervention in the Russian Civil War, Allied naval units operated in the Baltic Sea to support the independence of Estonia and Latvia, which were threatened by Bolshevik movements. The raid followed a similar one carried out by a single motor torpedo boat outside the harbour on 17 June 1919, in which Lieutenant Augustus Agar's CMB-4 sank the Bolshevik cruiser Oleg.
