Speedboats are considered the "short-distance runners" among ships, with high speeds reaching 40–60 knots and earning the nickname "light cavalry at sea". Classified by equipped weapons, speedboats include torpedo boats, missile boats, and missile-torpedo boats. Although small in size, speedboats are highly powerful and effective. For large and medium-sized enemy ships approaching coastal areas, torpedo boats and missile boats can operate individually or in coordination with other surface vessels to destroy these enemy ships. Speedboats can also be used to attack enemy transport fleets and disrupt their maritime transportation networks. With their high speed, compact hull, ability to hide, and capacity for sudden attacks on enemy bases and anchorage areas, speedboats can be employed to lay mines in shallow waters, narrow sea areas, and reef zones.

Among speedboats, missile boats stand out for their power. They inherit the advantages of torpedo boats and hold a very important position in naval warfare. However, compared to large and medium-sized ships, their self-defense capabilities are weaker, and their resistance to wind and waves is poor, allowing them to operate only in coastal areas.

Modern speedboats are widely equipped with missile weapons, advanced miniaturized electronic devices, high-power steam turbines, hydrofoils, and hovercraft technology. They are evolving towards directions such as missileization, larger size, higher speed, and electrification. In future naval battles, speedboats will play an even greater role.

Scientific Production:

1. Prepare the materials required for the experiment, such as EVA, measuring tubes, battery cases, motors, fan blades, etc.
2. Follow the instructions in the manual step by step for installation.
3. After installation, proceed with debugging.

Scientific Expansion:
Speedboats have a small displacement, high speed, and agile maneuverability. Their draft typically ranges from dozens to hundreds of tons, with a sailing speed of 30 to 40 knots, and some can reach up to 50 knots. Their endurance is between 500 and 3000 nautical miles. The boats are equipped with weapons; some also have ship guns with calibers ranging from 20 to 76 millimeters. Larger speedboats may also include mines or depth charges. The accompanying sensing systems include search, detection, weapon control, communication navigation, and electronic warfare functions.
