Different materials, different sources, but most agree that they have appeared owing to sea mines. Why sea mines? Quite simply, if you have a gun – you need support. Development began in the 18-19 age but not reached the required level. That's why experts say the successful use of the torpedo boats with only the 20 th century, to be more precise, since 1917. If studying a man who sees everything, he noted that during this time. First World War.
Namely, it was the British boat company "Thorneycroft". This model is also called "the 40-foot boat." However, they did not bring enough Vysokova result atttake as their followers, "the 55-foot boat." They were first used June 17, 1919 is already against the Soviet Baltic Fleet. Then the development of a few torpedo boats sank, not because of the fact that there were no opportunities for development, but because of lack of reasons for the development. However, when I started opportunity to mature. World War ii. Dramatically increased the number of light military equipment in general, especially in the ussr, including torpedo boats.
Each country of the enemy or allied countries had their torpedo boats. Y each had its advantages – higher development, lower, and depending on the economic and political situation of the country. So in England – it was mtv – speed 37 knot, 533-mm single-tube torpedo launchers, 2-3 guns Screening 7,62-12,7 mm to 4 depth charges. In Germany – S-Boot., Displacement of 115 tons, length 34.95 m, the speed to 40 knots, armament two 533-mm torpedo tubes and two 20-mm anti-aircraft gun. The Soviet boat was in first place on = basic criteria. F-5 – had displacement of 17 tons, a length of 20 m, speed over 50 knots, was armed with two 533-mm torpedoes (torpedo in the gutter) and two 7,62 mm or 12,7 mm machine guns. And, of course, the main countries for technical development to date – the United States. Boat type pt 103 – displacement of 50 tons, a length of 24 m, the speed to 45 knots, four 533-mm single-tube torpedo launchers, 12.7-mm machine guns and 40-mm anti-aircraft machine guns. But the war ended, and development has been somewhat on hold. Why? Because it appeared rocket weapons and their use more effectively. Many countries refused to torpedo boats completely and forever in favor of the missile. Only a few continued to use the boats – the ussr, Germany, Norway, Sweden, China, Israel, but times have changed, as now it was not necessary to attack the enemy has changed and the application – torpedo boats were used as patrol, fighting light forces, submarines. So what has changed and characteristics. Postwar boat was moving slowly – 42 knots, tonnage 268 tons, a length of 38.6 m, four 533-mm single-tube torpedo tubes (torpedoes '53-56 '), 2 twin automatic gun mount AK-230 (30 mm). But at the same time there were boats with missile-torpedo armament. By the end of 20 century torpedo boats nearly outlived itself – around the world there are only 162 rocket-torpedo, "clean" – 47. And the disappearance continues
