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 PT boat was a motor torpedo boat used by the United States Navy in World War II. It was small, fast, and inexpensive to build, valued for its maneuverability and speed but hampered at the beginning of the war by ineffective torpedoes, limited armament, and comparatively fragile construction that limited some of the variants to coastal waters. In the USN they were organized in Motor Torpedo Boat Squadrons (MTBRONs).
USS Dolphin (SF-10/SC-3/SS-169), a submarine and one of the "V-boats", was the sixth ship of the United States Navy to be named for that aquatic mammal. She also bore the name V-7 and the classifications SF-10 and SC-3 prior to her commissioning. She was launched on 6 March 1932 by the Portsmouth Navy Yard, sponsored by Mrs. E.D. Toland, and commissioned on 1 June 1932.
The Finnish Navy is one of the branches of the Finnish Defence Forces. The navy employs 2,300 people and about 4,300 conscripts are trained each year. Finnish Navy vessels are given the ship prefix "FNS", short for "Finnish Navy ship", but this is not used in Finnish language contexts. The Finnish Navy also includes coastal forces and coastal artillery.
E-boat was the Western Allies' designation for the fast attack craft of the Kriegsmarine during World War II; E-boat could refer to a patrol craft from an armed motorboat to a large Torpedoboot. The name of E-boats was a British designation using the letter E for Enemy,
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.
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).
Saukko (Pu110) was a small submarine that served in the Finnish Navy during the Second World War. It was designed not to exceed 100 tonnes, as it was planned for use in Lake Ladoga, and according to the 1920 Treaty of Tartu, no nation was allowed to use naval ships of more than 100 tonnes on the lake. The submarine could be divided into separate sections and transported by rail. The conning tower could be lifted off entirely. The engines were in the aft section and the batteries in the forward section. The name "Saukko" means European otter.
The Russian submarine AG-12 was an AG-class submarine, designed by the American Holland Torpedo Boat Company/Electric Boat Company, built for the Imperial Russian Navy during World War I. The submarine was fabricated in Canada, shipped to Russia and reassembled for service with the Baltic Fleet. She was scuttled by the Russians at Hanko in April 1918.
The AG-16 was an AG-class submarine, designed by the American Holland Torpedo Boat Company/Electric Boat Company, built for the Imperial Russian Navy during World War I. The submarine was fabricated in Canada, shipped to Russia and reassembled for service with the Baltic Fleet. The boat was originally named AG-13, but was redesignated AG-16 after AG-15 sank and later repaired in 1917. She was scuttled by the Russians at Hanko in April 1918.
VMV-class patrol boat was a series of Finnish patrol boats, which served with the Finnish Coast Guard and the Finnish Navy during World War II.
The Sisu-class motor torpedo boats was a series of two Italian MAS type motor torpedo boats of the Finnish Navy. The vessels were constructed in 1916 by the Orlando shipyard in Livorno, Italy. Sisu and Hurja were purchased by the Finns in 1920, and saw service in World War II. When dashing forward at full speed, the vessels sprayed water high in the air, earning the nickname "the fountains" from Finnish sailors.
The Syöksy-class motor torpedo boats was a series of four British Thornycroft type motor torpedo boats of the Finnish Navy. The vessels were constructed in 1928 by the John Thornycroft & Co. shipyard in Woolton, UK. The vessels saw service in World War II. The Thornycroft type released its torpedoes by dropping them from rails in the aft. The ship then had to steer away from the torpedoes path, a manoeuvre that could be quite tricky in the close waters of the Gulf of Finland.
The Finnish Navy used several different types of motor torpedo boats during World War II. Four Soviet motor torpedo boats were captured and commissioned by the Finnish Navy during the World War II. One of these was of larger D-3 class while three others belonged to G-5 class.
Coastal Motor Boat was a small high-speed British torpedo boat used by the Royal Navy in the First World War and up to end of the Second World War.
The G-5 was a Soviet motor torpedo boat design built before and during World War II. Approximately 300 were built, of which 73 were lost during the war. Four were exported to the Spanish Republican Navy during the Spanish Civil War and others were transferred to North Korea after the war. Three were captured by the Finns, but only two were used before all three had to be returned to the Soviets after the Moscow Armistice in 1944.
The Russian submarine AG-11 was an AG-class submarine, designed by the American Holland Torpedo Boat Company/Electric Boat Company, built for the Imperial Russian Navy during World War I. The submarine was fabricated in Canada, shipped to Russia and reassembled for service with the Baltic Fleet.
HM Motor Gun Boat 501 was a motor gunboat operated by Royal Navy Coastal Forces during the Second World War. The design, prepared by Bill Holt of the DNC's Boat Section, was unusual for a British light coastal forces' boat at the time in that it was of composite construction, whereas most MTBs and Motor Launches were entirely wooden-hulled. MGB 501's frames and various internal members were steel, with layers of diagonal wooden planking forming the exterior skin of the hull and wood for the remaining decks & bulkheads.
