How was the Submarine Controlled?
Submarines have been a crucial part of naval warfare for centuries, and their ability to operate underwater has made them a formidable force on the battlefield. But have you ever wondered how these underwater vessels are controlled? In this article, we’ll take a closer look at the history of submarine control systems and explore the various methods used to navigate and operate these complex machines.
Early Submarine Control Systems
The first submarines were developed in the 17th century, and they were controlled using simple systems that relied on manual manipulation of ballast tanks and propellers. Early submarines were essentially just wooden or metal tubes with a propeller and a rudder, and they were controlled by a team of sailors who used hand cranks and pulleys to adjust the ballast tanks and change the submarine’s buoyancy.
Hand-Cranked Propellers
The first submarines were equipped with hand-cranked propellers, which were powered by a team of sailors who turned the cranks to propel the submarine through the water. This system was slow and laborious, and it limited the submarine’s speed and maneuverability.
Ballast Tanks
Submarines also used ballast tanks to control their buoyancy and depth. By filling or emptying the tanks with water or air, the submarine could change its buoyancy and dive or rise to different depths. This system was controlled by manual valves and pumps, which were operated by the submarine’s crew.
Hydroplanes
In the late 19th century, submarines began to use hydroplanes to control their depth and direction. Hydroplanes are flat surfaces that are mounted on the sides of the submarine, and they use the pressure of the water to change the submarine’s direction and depth. This system was more efficient than the hand-cranked propellers and allowed submarines to dive and rise more quickly.
Electric Propulsion
In the early 20th century, submarines began to use electric propulsion systems, which were more efficient and quieter than the earlier systems. Electric motors were powered by batteries, which were recharged by diesel generators or nuclear reactors. This system allowed submarines to operate for longer periods of time without surfacing.
Modern Submarine Control Systems
Today, submarines are equipped with sophisticated control systems that use digital computers and sensors to navigate and operate. These systems include:
- Dive planes: These are flat surfaces that are mounted on the sides of the submarine and use the pressure of the water to change the submarine’s direction and depth.
- Ballast tanks: These are used to control the submarine’s buoyancy and depth. By filling or emptying the tanks with water or air, the submarine can change its buoyancy and dive or rise to different depths.
- Propulsion motors: These are electric motors that are powered by batteries or diesel generators. They provide the power needed to propel the submarine through the water.
- Control surfaces: These are the rudder and the hydroplanes, which are used to control the submarine’s direction and depth.
- Sensors and navigation systems: These include sonar, radar, and GPS systems, which provide the submarine’s crew with information about their surroundings and location.

| System | Description |
|---|---|
| Dive planes | Flat surfaces that change the submarine’s direction and depth |
| Ballast tanks | Used to control the submarine’s buoyancy and depth |
| Propulsion motors | Electric motors powered by batteries or diesel generators |
| Control surfaces | Rudder and hydroplanes used to control direction and depth |

Conclusion
Submarine control systems have evolved significantly over the centuries, from simple manual systems to sophisticated digital systems. Today, submarines are equipped with advanced control systems that use digital computers and sensors to navigate and operate. These systems allow submarines to operate for longer periods of time without surfacing and provide the crew with accurate information about their surroundings and location.
