What Drove the Invention of Submarines?

The Invention of Submarines

Exploring the Ocean Depths

Humans have always been fascinated by the mysteries of the ocean and its depths. The desire to explore the underwater world and its potential resources has been a driving force behind the invention of submarines. In addition, as naval warfare developed, there was a need for advancements in submarine technology, making them essential additions to military operations.The first recorded attempt at creating a submarine was by Dutch inventor Cornelis Drebbel in 1620. However, it was not until 1776 that American inventor David Bushnell built a small, wooden submersible called the Turtle. The Turtle was powered by a hand-cranked propeller and was propelled by divers who turned a crank to make the propeller turn. Despite being the first submarine to be used in battle, the Turtle was not effective and dangerous to operate.

The Earliest Submarines

As technology advanced, so did the design of submarines. In the early 1800s, French inventor Robert Fulton built the Nautilus, which was powered by a steam engine, making it the first mechanically powered submarine. However, like the Turtle, the Nautilus was also not effective as a military machine.The Civil War in the United States saw the invention of the first submarine to sink an enemy ship. The Confederate submarine H.L. Hunley was used to attack and sink the Union warship Housatonic. However, the Hunley itself was lost with all hands, as it sank shortly after the attack.

The Modern Submarine

It was not until the late 19th and early 20th centuries that modern submarine technology emerged. The first successful modern submarine was the USS Holland, designed by Irish-American inventor John Philip Holland. The USS Holland was commissioned by the United States Navy in 1900 and was powered by an internal combustion engine. It was also armed with torpedo tubes and could dive up to 200 feet. The USS Holland was a turning point in the development of the submarine, representing the first fully functional submarine for the U.S. Navy.Modern submarines rely on advanced technology, including sonar, periscopes, and computer systems to navigate and carry out their missions. They are designed to be faster, more durable, and capable of deeper dives than their predecessors. They are also equipped with advanced weapons systems, including torpedoes and missiles, making them formidable weapons in modern naval warfare.In conclusion, the invention of submarines was driven by our desire to explore and understand the depths of the ocean, as well as the need for technological advancements in naval warfare. From the early attempts at creating crude submersibles to the advanced modern submarines that we know today, the development of this technology represents a significant milestone in human history.

The Role of Submarines in Warfare

Stealth Operations

Submarines are an essential component of modern naval warfare. One of their most significant advantages is their ability to operate covertly and stealthily. The underwater environment makes it difficult for traditional navigation and detection methods to track submarines, making them almost invisible to enemy forces. Therefore, submarines become an invaluable asset for covert operations in naval warfare. They can enter into enemy territory undetected, gather intelligence, and launch surprise attacks on enemy vessels. This level of stealth and tactical advantage is unmatched by any other naval vessel.

Submarines provide versatility while carrying out missions in the water, too. They can remain hidden and operate silently for extended periods, even months, without any support or refuel. This advantage makes them highly adaptable and efficient, as they can travel around the world, complete missions, and return without any interruption or hindrance.

Mutually Assured Destruction

The development of nuclear submarines and their ability to launch nuclear missiles created a strategic balance of power during the Cold War. The term "Mutually Assured Destruction" (MAD) became the foundation of nuclear deterrence theory. The concept of MAD recognized the reality that, in a nuclear war, both adversaries would face the threat of catastrophic destruction, leading to the assurance that neither would initiate a nuclear attack against the other.

Both the United States and the Soviet Union built highly advanced nuclear submarine fleets, each with its launch capabilities. This inherent unpredictability of a submarine's location and movement made an attack against an enemy's subs an impossible task. The presence of nuclear submarines gave countries mutually assured destruction and negated any strategic advantage that a surprise attack might have provided, making nuclear war unlikely and unproductive.

Anti-Submarine Warfare

Submarines not only provide a significant tactical advantage but also necessitate the development of countermeasures. The development of anti-submarine warfare tactics and technology in response to the threat of submarines has played a critical role in modern naval warfare. Countries have invested billions of dollars to counter the threat posed by submarines.

The development of sonar systems equipped with advanced technology, like magnetic anomaly detectors and passive acoustic detection systems, have made submarine detection possible. Anti-submarine warfare (ASW) technologies have evolved significantly since the early days, providing necessary protection to surface fleets and reducing the vulnerability of sea lanes. ASW measures, including helicopters, depth charges, and torpedoes, have all developed to counter the stealthy submarine threat.

In conclusion, the invention of submarines for naval warfare has revolutionized modern warfare. Hidden underwater, the submarines offer great tactical advantages, making them indispensable assets during times of war. The development and investment in anti-submarine warfare have allowed navies to combat this threat successfully. While the threat of mutually assured destruction may sound formidable, it maintains global stability, giving countries peaceful options to resolve conflicts and maintain international relations.

The Impact of Submarines on Society

Undersea Exploration and Scientific Research

Submarines have revolutionized our understanding of the deep ocean and helped scientists study the marine environment in ways that were previously impossible. Before the advent of submarines, researchers were limited to studying the ocean's surface and what washing up on shore. Submarines equipped with advanced sensors and sampling equipment have allowed scientists to explore the hidden depths of the ocean and discover new species of marine life.

In addition, submarines have played a crucial role in oceanographic research. The first submarine to undertake an oceanographic mission was the French Navy's Gymnote in 1888. Since then, submarines have been used to undertake a variety of scientific missions, such as measuring ocean currents and temperatures, studying marine geology, and mapping the ocean floor.

Commercial and Industrial Uses

Submarines have not only had an impact on scientific research but also have numerous commercial applications. One major use is for deep-sea oil and gas exploration, where submarines are used to inspect pipelines and geological formations. In addition, submarines play an important role in undersea mining, which involves extracting minerals from the ocean floor.

Another commercial use of submarines is in the installation and repair of underwater infrastructure. For example, submarines are used to lay undersea cables and repair offshore oil rigs. Submarines are ideal for these tasks because they can work at great depths, where most traditional diving methods are impossible.

Environmental Impacts

The deployment of submarines has had both positive and negative environmental impacts. On one hand, submarines have increased our understanding of the ocean environment. Thanks to submarines, we have been able to study previously unknown habitats, observe the behavior of deep-sea creatures, and identify new species. In addition, submarines have also played a role in ocean conservation efforts by helping to locate and study marine protected areas.

However, the deployment of submarines can also have negative environmental impacts. The propellers and engines of submarines can create noise pollution, which can disturb marine animals and interfere with their communication and navigation. Submarine periscopes and masts can also cause physical damage to coral reefs and other delicate marine habitats. Finally, the discharge of waste from submarines can contribute to pollution in the ocean environment.
