16 Different Types of Submarines

Different Types Of Submarines

The different types of submarines are vessels that perform operations and activities underwater.

Submarines have a long history of use, particularly during wartime when they are deployed as stealth weapons to destroy enemy naval vessels.  

Submarines, on the other hand, have been used in a variety of ways over the years.

This broadening of the spectrum of use has resulted in the creation and innovation of newer submarine technologies.  

Furthermore, Submarines are available in a variety of shapes, sizes, and configurations, and can be employed as warships, exploration vehicles, scientific research vessels, tourism vehicles, commercial vehicles, or just for fun.  

The submarine’s design and capabilities are dictated by its mission and intention. However, submarines and spacecraft are extremely similar.  

They are vehicles that allow us to explore a hazardous environment and without which we would not be able to endure these unknown and perilous circumstances.

Submarines allow us to explore the depths of our world, while spaceships allow us to travel beyond our planet.  

Many of these vehicles are fascinating, intriguing, and inventive in design; a monument to man’s ingenuity.

Additionally, the following are some of the different types of submarines that have been developed over the years: 

1. Mechanically Powered Submarines

The creation of mechanical power for these watercraft was a significant step in submarine history. Additionally, the first mechanically powered submarine was launched in 1863, and it propelled itself with compressed air. 

Diesel-electric propulsion became the preferred power system for submarines as technology advanced in the late 1800s and early 1900s.  

Furthermore, when the submarine was on the surface, diesel engines were utilized to provide propulsion and charge the bank of batteries that were needed to keep the submarine running when it was submerged. 

2. Human Powered Submarines

All of the early different types of submarines designs were powered by humans. Early ships were propelled by oars, which were manned by crew members. However, manual bilge clearance was assigned to other members of the submarine crew.  

Furthermore, Later versions of the submarine, such as the well-known Nautilis, were propelled by a screw propeller rather than oars and were designed by an American, Robert Fulton, who was living in France at the time.  

The crew had to turn this screw by hand. This ship was built as a warship with the mission of delivering naval mines to destroy merchant’s vessels. 

3. Personal submarines

Personal submarines, sometimes known as recreational submarines, are submarines that are used for recreational or research purposes. Submarines of this type were first developed in the 1970s by Graham Hawkes for use as navy vessels.  

Also, they have become extremely essential in the field of marine science and recreation in recent years. Furthermore, personal recreational submarines can now be found on mega-yachts and huge cruise ships. 

4. U-boat

During World War II, German warships known as U-boats were extremely important to German naval forces. The U-boat is one of the different types of submarines used by the Germans.  

Developing U-boat technology reflected German troops’ unwavering commitment to winning World War II. The U-27 was the first U-boat to be launched, and it was launched in 1939.  

Additionally, despite occasional success against enemy warships, these submarines’ principal mission was to hunt down merchant fleets from the United States, Canada, and the United Kingdom.  

However, U-boats hunted these fleets in packs, known as wolf-packs, and were extremely effective until allies discovered numerous effective defenses. 

5. Narco-Submarines

Submarines aren’t just for scientific research, economic ventures, or military purposes. Submarines have recently been used by criminals to smuggle drugs.  

Additionally, submarines or semi-submarines used to transport illegal substances unnoticed are known as narco-submarines.  

Also, South American drug smugglers transport their wares to US coastal seas in this sort of drug trafficking. Furthermore, this method can be used to carry large amounts of narcotics. 

6. Midget Submarines

Persons of short-stature submarines are named after their minuscule size, as one might imagine. Because they were not huge vessels, most of the early submarines fell under this category.  

Also, Midget submarines are any submarine that weighs less than 150 tons and may be operated by as little as two or as many as nine people.  

Furthermore, they can be used for military goals, such as shallow harbor invasions, or civilian purposes, such as exploration, underwater maintenance, and scientific research.  

Meanwhile, these compact vessels are usually equipped with no sleeping or cooking facilities and are intended for short missions. Military versions were frequently utilized to deploy combat divers near to their targets and to retrieve these divers when the mission was completed. 

7. Air-independent Propulsion Submarines

These different types of submarines are with air-independent propulsion or AIP. They use alternate techniques to feed oxygen to engines that ordinarily require air for burning.  

These submarines are mainly non-nuclear submarines that use diesel or other sorts of combustion engines to power them. Initially, researchers were looking for a fuel that could burn anaerobically, but their focus shifted to finding a way to give oxygen to combustion engines. 

8. Submersible

The submersible is part of the different types of submarines designed for a variety of objectives, including scientific, commercial, and military.  

Additionally, a submersible is a small submarine that can be manned or unmanned. Their size and function set them apart from other submarines and placed them in their category.  

Also, they are mostly employed for research or commercial applications, such as pipeline or oil rig maintenance. 

9. Military Submarines

Submarines are important strategic vessels for any country with a big coastline to defend and a strong naval force.

Furthermore, a military submarine is a submersible vessel that is used for military purposes, such as defending a country from an enemy or defending the country’s borders.  

Military submarines are classified into several categories based on their power source, characteristics, and intended use.

Meanwhile, submarines are used as operational warships in the navies of over 46 countries.  

Most of these submarines are non-nuclear. Only six countries currently have nuclear submarines in their fleets: the United States, the United Kingdom, Russia, France, China, and India. 

10. Fast Attack Submarines

Fast attack submarines are one of the different types of military submarines created with a single mission in mind. They are also known as hunter-killer submarines, which hints at their mission.  

Hunter-killer submarines, often known as fast attack submarines, are meant to hunt down and destroy enemy submarines and warships.  

Furthermore, they usually carry torpedo weaponry for sinking enemy submarines and ships rather than vertical launch capability. They can be nuclear-powered or diesel-powered vessels. 

11. Single Hull Submarines

Submarine designs have evolved as we’ve learned more about the effects of water pressure on the hull, especially at greater depths.  

A single hull submarine is a vessel with a single pressure hull meant to protect the crew from the perils of deep water’s high pressure. A cylindrical hull is the best shape for a pressure hull.  

However, it is not the best form for underwater speed. Furthermore, many early submarines, submersibles, and modern submarines and submersibles feature a single pressure hull, but larger submarines, particularly military boats, require speed, which the single-hull design couldn’t give. 

12. Double Hull Submarines

Engineers and submarine builders quickly learned that the ideal hull shape for pressure protection was not the best form for gliding through the water with the least amount of resistance and speed.  

Furthermore, submarines with a double hull have an inner pressure hull that protects the crew from the pressure and an outside non-pressure hull that gives the submarine the ideal form for cutting through the water with minimal resistance, boosting speed and efficiency. 

13. Bathysphere

Divers are frequently taken to dangerous depths where they can operate from a position of relative safety to explore the ocean’s depths. For this reason, the bathysphere was invented.  

Furthermore, a bathysphere is a spherical, non-powered submersible used to lower and rescue divers from vast depths and explore and study the deep-sea environment, which is one of the different types of submarines. A steel rope attached to a ship on the surface lowers the craft to depth. 

14. Bathyscaphe

Normal submarines can’t reach the deepest portions of the ocean because the pressure would destroy their hulls. For this form of expedition, a specialized craft is required.  

Additionally, a bathyscaphe is a self-propelled submersible with a crew compartment that is suspended beneath afloat rather than from a ship’s cable.  

Furthermore, for maritime exploration, Auguste Piccard, a Swiss inventor and adventurer, designed it.  

The Challenger Deep in the Mariana Trench was reached by Jacques Piccard, Auguste Piccard’s son, and Don Walsh with a vehicle of this type. However, the record depth was almost 35,000 feet (10 kilometers) deep. 

15. Air-sea Rescue Submarines

Submarines were crucial rescue ships as well as a sneaky means of attacking the enemy. Also, during World War II, a group of submarines known as the Lifeguard League of Submarines was entrusted with rescuing downed fighter pilots in the Pacific.  

Before air attacks, these vessels were strategically positioned to rescue downed pilots or pilots who had to ditch their planes. Furthermore, the submarines’ air-sea rescue mission became one of the most important operations undertaken by submarines in the Pacific during WWII. 

16. Human Torpedoes

Submarines, known as human torpedoes, were employed to launch missiles at enemy naval vessels.  

Additionally, human torpedoes were widely used by the Italian, British, Egyptian, and Greek naval forces since the First World War, and they were an important aspect of naval warfare. 

Conclusively, the different types of submarines and other underwater craft of various types have contributed to expanding the scope of existing nautical operations.  

Submarine technology is becoming increasingly crucial and integral in the execution of possible undersea operations, even as their role has varied.
