Submarines have become one of the most critical and sophisticated elements of sea war technology. Their ability to operate continuously Water underwater, their stealth advantage, and their payload capacity have secured them a vital place among the indispensable assets of naval forces place.

The concept of the submarine extends as far back as the 16th century historical. The earliest sketches of vessels capable of operating underwater appear in the drawings of Leonardo da Vinci. However, the first practical and functional submarine was built in 1620 by Cornelius Drebbel. During tests on the River Thames, this manually powered vehicle successfully navigated underwater distances (Konur, 2019).
The 18th and 19th centuries were marked by trial and error in submarine development. In 1863, the steam-powered submarine “Plongeur,” developed by France, entered history as the first mechanically propelled submarine. This period also initiated a process in which the potential offensive power of submarines became evident with the advancement of torpedo systems military.
With the development of diesel-ELECTRIC electricity engines in the early 20th century, together, submarines gained increased range and submerged endurance. These engines allowed submarines to operate on diesel fuel while surfaced and switch to electric motors when submerged, enabling quieter and more covert operations.
In 1954, the USS Nautilus, developed by USA, became the first submarine powered by nuclear energy. Nuclear-powered submarines can remain operational for years without refueling, significantly enhancing their strategic advantage (Polmar & Moore, 2004). Moreover, the energy provided by nuclear reactors enables them to sustain high speeds over long distances.
Today, submarines operate integrated with artificial intelligence-assisted navigation systems, advanced sonars, acoustics camouflage systems, fiber-optic communication technologies, and unmanned underwater vehicles. These technologies have rendered the detection of submarines underwater nearly impossible.
During World War II, particularly German “U-Boat” submarines, had a significant impact in the Atlantic. These submarines, used to disrupt Trade supply routes, became one of the war’s decisive factors (Blair, 1996). During the Cold War, submarines acquired the capability to carry nuclear-tipped ballistic missiles, thereby establishing a “second-strike” capability.
Modern submarines serve a variety of mission profiles:
Many nations, including Türkiye, are actively developing modern submarines to establish strategic superiority in this domain. Türkiye’s Reis-class submarine project is an example of this strategy.
Because submarines operate in enclosed, pressure-resistant environments, interior space design carries significant importance. In military submarines, factors such as crew accommodation, military ergonomic, mission allocation, and security like also play decisive roles (Kılıç, 2020).
In addition, the arrangement of living spaces, lighting, and acoustic insulation are critical for maintaining psychological resilience during prolonged missions.
Submarines are not only used for military purposes but also in civilian fields such as deep-sea research, mineral extraction, cable flooring inspection, and natural disaster analysis. Vehicles capable of reaching the deepest regions of the ocean, such as the Mariana Trench, provide valuable data about the Earth’s unknown areas.
Submarine technologies are becoming increasingly autonomous thanks to advances in artificial intelligence and unmanned systems. Countries such as the United States, China, and Russia continue R&D efforts on fully unmanned, AI-controlled submarines.
In addition, to enhance stealth, magnetic propulsion systems, advanced carbon-composite hulls, and biomimetic biomimetic designs (fish-like shapes) are gaining prominence.
Submarines are technologically advanced vessels with profound historical and strategic significance. The capabilities they offer in both military and civilian domains have made them one of the most remarkable engineering achievements of the 21st century. In the coming years, submarines integrated with artificial intelligence and robotic systems are expected to reshape global military balances.
