Its first engagement was to try to break the blockade of British ships at New York harbour. The pilot was supposed to use The Turtle to reach the line of ships and fasten a pound bomb to the keel of one, thus breaking the line.
The attempt was unsuccessful. Early in the s, Swedish inventor Thorsten Nordenfeldt built the first steam-powered submarines. The Nordenfeldt III could submerge to a depth of 50 feet and had a range of 14 miles. A steam engine powered the submarine on the surface and was shut down to dive. Nordenfeldt III also had twin torpedo tubes and was the first vessel to fire an underwater torpedo.
Britain and Germany were engaged in a naval arms race at the start of the 20th Century, both in terms of traditional surface ships and submarines. The submarine would show its strategic value during the First World War, with German submarines easily sinking both battleships and passenger vessels, often with a single torpedo. They became more powerful as the war progressed, with the model U reaching feet in length, able to carry two medium-calibre deck guns with a vastly superior range to other ships.
When Hitler came to power, he immediately began rearming the German navy and focused on developing more powerful submarines, resulting in the infamous U-boat. The U could reach 19 knots while fully submerged. New submarines could travel much further and stay submerged for longer than their WWII predecessors, making them far more dangerous.
Equipped with ballistic missiles and nuclear warheads, these submarines would often stay at sea for weeks or even months, waiting tensely for orders and scanning the ocean for any sign of enemy ships. Nuclear submarines are still in use today, most famously in the UK Trident system. Submarines are now used for exploration and are a vital part of the Marine sector.

Wilhelm Bauer built his first submarine in , but only narrowly escaped with his life after it sank in 50 feet of water during a demonstration. Undeterred, the Bavarian inventor continued experimenting and eventually received funding from the Russian government for a new vessel.
After traveling to St. The ship boasted several technological breakthroughs including multiple ballast tanks for added buoyancy, a crude airlock and a propeller that was powered by crewmen operating an internal treadmill. Its most unusual feat came during the coronation of Czar Alexander II, when it submerged with a four-member brass band aboard.
Witnesses later reported that they could hear a rendition of the Russian national anthem coming from beneath the waves. Drawing of Hunley on a pier. The primitive attack sub H. Hunley was designed to help the Confederacy escape the stranglehold of Union naval blockades during the Civil War. Built privately in Mobile, Alabama, in , it was fashioned from a recycled iron steam boiler and included space for eight crewmen—one to steer, and seven to turn the hand cranks that powered its propeller.
Its bow bristled with a foot spar mounted with a torpedo, which would detonate when rammed against an enemy ship. It sank on two occasions during its trial runs, killing a total of 13 crewmen including its namesake, marine engineer Horace Lawson Hunley. The sub was repeatedly salvaged, however, and on February 17, , Lieutenant George Dixon and a crew of volunteers sailed it into Charleston Harbor and successfully drove its torpedo into the side of the sloop-of-war USS Housatonic.
The Union vessel went down in minutes, but the Hunley also sank, possibly because of damage sustained during its attack. Despite becoming the first submariners in history to destroy an enemy ship, Dixon and his Confederates all perished. Rather than relying on hand cranks, foot pedals or treadmills to move its propeller, this foot behemoth used a piston engine powered by compressed air stored in tanks.
The air also helped provide the crew with oxygen and served as a means for automatically emptying its ballast tanks. Le Plongeur made several successful dives, but its limited air supply and dangerously unstable structural design led to it being removed from active duty in Drawing of Monturiol and his submarine. The successor to an earlier diving boat called Ictineo I, the foot Ictineo II achieved remarkable stability thanks to a system of weights and four pump-operated ballast tanks positioned inside its double-hull.
To turn its propeller, Monturiol developed an anaerobic steam engine that used a chemical reaction to create both heat and oxygen. The engine seems to have worked—Monturiol made a successful dive in late—but the sub was later sold for scrap due to funding shortages.
Its groundbreaking propulsion system would not be replicated until the 20th century. Submarine technology had improved by leaps and bounds by the lateth century, but most undersea boats were still only capable of completing short runs close to shore. That changed in , when American engineer Simon Lake built the Argonaut, a foot craft powered by a horsepower gasoline engine.
It also had a periscope, a diving chamber and a floating hose to provide air for the engine and crew.
