I want to go sightseeing by speedboat. What formalities do I need?
First, speedboats are small in tonnage, fast in speed and flexible. The displacement is generally tens to hundreds of tons, the sailing speed is 30 to 40 knots, some can reach 50 knots, and the endurance is 500-3000 nautical miles. The boats are equipped with weapons, and some speedboats are also equipped with naval guns of 20 to 76 mm caliber. A speedboat with a larger tonnage may also be equipped with mines and depth charges. Matching sensing system includes search, detection, weapon control, communication and navigation, electronic warfare and so on.
Second, the speedboat is the "sprint champion" in the ship, with a maximum speed of 40-60 knots, and is known as the "marine light cavalry". Speedboats are classified according to the weapons they are equipped with, including torpedo boats, missile boats and missile torpedo boats. Although the speedboat is small, it is powerful and plays a great role.
3. For large and medium-sized enemy ships invading offshore, torpedo boats and missile boats can attack alone or cooperate with other surface ships to destroy the invading large and medium-sized enemy ships. You can also send speedboats to attack the enemy's transport fleet and destroy the enemy's maritime transport lines. The speedboat is fast, small in size, can be hidden, and can effectively attack enemy bases and berths suddenly. In shallow waterways, narrow seas, reefs and other places, speedboats can be used to mine.
Fourthly, the most powerful speedboat is missile boat, which inherits the advantages of torpedo boat and plays a very important role in naval battle. However, compared with large and medium-sized ships, they have weak self-defense ability and poor wind and wave resistance, so they can only fight in the offshore.
Fifth, modern speedboats are widely used in missile weapons, advanced miniaturized electronic equipment, high-power gas turbines, hydrofoils and air cushion technology, and are developing in the direction of missile, large-scale, high-speed and electronic. In the future naval battle, speedboats will play a greater role and be of great help to people in the army.
6. The first torpedo boat in the world was the Lightning built by Britain in 1877. Almost at the same time as Britain, Russian-built Cessme and Sinop torpedo boats can also be regarded as the earliest prototype torpedo boats. 1887 65438+1October13rd, the "Cesme" and "Sinop" torpedoed the Turkish navy's communication ship "Guo Thiebach" for the first time.
