The last Redoutable class submarine was decommissioned in China launched its first nuclear armed submarine in April The Chinese Navy is estimated to have 24 JL-1s. The JL-1 is basically a modified DF Deployment on the JL-2 reportedly began in late Attack submarines are fast, long range boats with torpedoes and cruise missiles to attack submarines, ships and land targets.
They carry sonars, and other sensors, for target location and fire control systems for weapon launching. The submarine was commissioned in It had twice the weapon load of the Los Angeles class, with a new combat system BSY-2 and new sonars.
Unfortunately its cost proved unacceptable and so a more affordable design was started. This Virginia class had a reduced weapon load but with a wide variety of types. The Royal Navy is building the Astute -class submarines as successors to its Swiftsure and Trafalgar classes.
The first was launched in The latest Chinese attack submarine class is the Type Shang , first launched in , which is replacing the Type Han class.
Older attack submarines have been decommissioned. The French Barracuda -class submarine is under construction the first is planned to be launched in and will totally replace its Rubis -class attack submarines in These boats are lead-acid battery powered, being charged between runs from support facilities. They may have a surface speed of a few knots but generally their underwater speed is less than a knot.
Their depth capabilities are often only a few metres. Some are capable of carrying over 50 passengers. They are found in the major tourist resorts in the warm water regions.
These can be used for a variety of purposes from scientific research, underwater filming and construction to search and salvage. They often can be fitted with a number of tools with lights, cameras, acoustic tracking and communications. They tend to be 2 or 3 person craft, sometimes with diver lockout facilities. Alternatively they can be simple craft used to aid divers. The 9th races were held in at which 22 teams took part, with 26 submarines.
A speed record of 8 knots was set for a two man submarine and 5 knots for a one man submarine. Up to August there were 68 submarine accidents.
There were 23 collisions, 7 battery gas explosions, 12 gasoline explosions, and 13 sinkings due to hull openings not being closed. There have been a number of accidental sinkings but also some collisions between submarines. Examples of the former include the loss of HMS Affray in the English Channel in due to the snort mast fracturing, USS Thresher in due to a pipe weld failure during a test dive, however many other scenarios have been proven to be probable causes of sinking, most notably a battery malfunction causing a torpedo to detonate internally, and the loss of the Russian Kursk on 12 August probably due to a torpedo explosion.
Since submarines have been actively deployed, there have been several incidents involving submarines that were not part of major combat.
Most of these incidents were during the Cold War, but some are more recent. Since the year there have been 9 major naval incidents involving submarines. There were three Russian submarine incidents, in two of which the submarines in question were lost, along with three United States submarine incidents, one Chinese incident, one Canadian, and one Australian incident. Until the advent of nuclear marine propulsion , most 20th-century submarines used batteries for running underwater and gasoline petrol or diesel engines on the surface and to recharge the batteries.
Early boats used gasoline but this quickly gave way to kerosene, then diesel, because of reduced flammability. Diesel-electric became the standard means of propulsion. Initially the diesel or gasoline engine and the electric motor were on the same shaft, which also drove a propeller with clutches between each of them. This allowed the engine to drive the electric motor as a generator to recharge the batteries and also propel the submarine if required.
The clutch between the motor and the engine would be disengaged when the boat dived so that the motor could be used to turn the propeller. The motor could have more than one armature on the shaft—these would be electrically coupled in series for slow speed and parallel for high speed known as "group down" and "group up" respectively. In the s the principle was modified for some submarine designs, particularly those of the U.
Navy and the British U-class. This diesel-electric propulsion allowed much more flexibility, for example the submarine could travel slowly whilst the engines were running at full power to recharge the batteries as quickly as possible, reducing time on the surface, or use its snorkel.
Also it was now possible to insulate the noisy diesel engines from the pressure hull making the submarine quieter. There were other power sources attempted—oil-fired steam turbines powered the British "K" class submarines built during the First World War and in following years but these were not very successful.
This was selected to give them the necessary surface speed to keep up with the British battle fleet. Steam power was resurrected in the s with the advent of the nuclear-powered steam turbine driving a generator, which is now used in all large submarines. There was an attempt to use a very advanced lead cooled fast reactor on Project " Lira " but it's maintenance was considered too expensive. By removing the requirement for atmospheric oxygen these submarines can stay submerged indefinitely so long as food supplies remain air is recycled and fresh water distilled from seawater.
Anaerobic propulsion was employed by the first mechanically driven submarine Ictineo II in Ictineo's engine used a chemical mix containing a peroxide compound, that generated heat for steam propulsion while at the same time solved the problem of oxygen renovation in an hermetic container for breathing purposes. The system wasn't employed again until when the German Navy tested a system employing the same principles, the Walter turbine, on the experimental V submarine and later on the naval U submarine.
The results were not encouraging enough for this technique to be adopted at the time, although the Russians deployed a class of submarines with this engine type code named Quebec by NATO, they were considered a failure.
Today several navies, notably Sweden now use air-independent propulsion boats, which substitute liquid oxygen for hydrogen peroxide.
The German Type submarine uses nine kilowatt hydrogen fuel cell as air-independent propulsion, which makes it first series production submarine using fuel cell. Most small modern commercial submarines that are not expected to operate independently use batteries that can be recharged by a mother-ship after every dive. Towards the end of the 20th century, some submarines began to be fitted with pump-jet propulsors instead of propellers.
Although these are heavier, more expensive, and often less efficient than a propeller, they are significantly quieter, giving an important tactical advantage. A possible propulsion system for submarines is the magnetohydrodynamic drive , or "caterpillar drive", which has no moving parts.
It was popularized in the movie version of The Hunt for Red October , written by Tom Clancy, which portrayed it as a virtually silent system. In the book, a form of propulsor was used rather than an MHD. Although some experimental surface ships have been built with this propulsion system, speeds have not been as high as those hoped.
In addition, the noise created by bubbles, and the higher power settings a submarine's reactor would need, mean that it is unlikely to be considered for any military purpose. Drebbel's submarine is thought to have incorporated floats with tubes to allow air down to the rowers.
The steam powered submarines used to run with their hulls awash with air being taken down through their conning towers. During the First World War the British are believed to have experimented with a similar concept to the schnorkel, that is a mast through which air is drawn. Diesel submarines needed air to run their engines, and so carried very large batteries for submerged travel.
These limited the speed and range of the submarines while submerged. The schnorchel used by prewar Dutch submarines was used after to allow German submarines to run just under the surface, attempting to avoid detection visually and by radar.
After the war the concept became widely used and the term was anglicised to "shnorkel" or "snorkel" in English. The German navy also experimented with engines that would use hydrogen peroxide to allow diesel fuel to be used while submerged, but technical difficulties were great. Originally submarines were navigated using a porthole but the periscope was introduced by World War I. Today the submarine may have a wide variety of sonar arrays, from bow mounted to trailing ones.
There are often upward-looking under-ice sonars as well as depth sounders. Originally the submarine's torpedoes were aimed by pointing the boat in the correct direction. This was determined from the targets course and speed by measurements of angle and range via the periscope. The necessary calculation was first carried out manually and later by mechanical calculators. Today it is achieved by digital computers with display screens providing all necessary information on the torpedo status and ship status.
Early submarines carried torpedoes externally and then internally. In the latter case both bow mounted and stern mounted tubes were used but today only the former are still employed. Some specialised mine laying submarines were built. The modern submarine is capable of firing many types of weapon from its launch tubes, including UAVs. Up until the end of WW2 it was common to fit deck guns to submarines to allow them to sink ships without wasting torpedoes.
German submarines in World War II had rubber coatings and could launch chemical devices to provide a decoy when the boat was under attack. These proved to be not very effective as sonar operators came to distinguish between the decoy and the submarine.
Modern submarines can launch a variety of devices for the same purpose, as well as having coatings. Wireless was used to provide communication to and from submarines in the First World War. With time the type, range and bandwidth of the communications systems have increased. Because of the danger of intercept, transmissions by a submarine are minimised.
Various periscope mounted aerials have been developed to allow communication without surfacing. The standard navigation system for early submarines was by eye, with use of a compass. The gyrocompass was introduced in the early part of the 20th century and inertial navigation in the s.
The use of satellite based navigation is of limited use to submarines, except at periscope depth or when surfaced. After the sinking of the A1 submarine in , lifting eyes were fitted to British submarines and in air-locks and escape helmets were provided. His creation was a wooden framework bound in waterproofed leather. It was to be submerged by using hand vises to contract the sides and decrease the volume. Although Bourne's idea never got beyond the drawing board, a similar apparatus was launched in But it didn't get much farther because the designers had neglected to consider the tenacity of underwater mud.
The craft became stuck in the river bottom during its first underwater trial. What might be called the first "practical" submarine was a rowboat covered with greased leather. Van Drebbel's submarine was powered by rowers pulling on oars that protruded through flexible leather seals in the hull.
Snorkel air tubes were held above the surface by floats, thus permitting a submergence time of several hours. Van Drebbel's submarine successfully maneuvered at depths of 12 to 15 feet below the surface of the Thames River.
Van Drebbel followed his first boat with two others. The later models were larger but they relied upon the same principles. Legend has it that after repeated tests, King James I of England rode in one of his later models to demonstrate its safety. Despite its successful demonstrations, Van Drebbel's invention failed to arouse the interest of the British Navy.
It was an age when the possibility of submarine warfare was still far in the future. In the British periodical "Gentlemen's Magazine" printed a short article describing a most unusual device for submerging and surfacing. Reproducing an Italian scheme developed by Giovanni Borelli in , the article depicted a craft with a number of goatskins built into the hull. Each goatskin was to be connected to an aperture at the bottom.
Borelli planned to submerge this vessel by filling the skins with water and to surface it by forcing the water out with a twisting rod. Even though Borelli's submarine was never built it provided what was probably the first approach to the modern ballast tank.
The first American submarine is as old as the United States itself. David Bushnell , a Yale graduate, designed and built a submarine torpedo boat in The one-man vessel submerged by admitting water into the hull and surfaced by pumping it out with a hand pump. Powered by a pedal-operated propeller and armed with a keg of powder, the egg-shaped Turtle gave Revolutionary Americans high hopes for a secret weapon - a weapon that could destroy the British warships anchored in New York Harbor.
The Turtle's torpedo, a keg of powder, was to be attached to an enemy ship's hull and detonated by a time fuse. However, the boring device that was operated from inside the oak-planked Turtle failed to penetrate the target vessel's hull. The military troop divers cleared obstructions using primitive kind of submarines. The history of submarines is as old as 2, years [Now it is ]. His principle was very well used to design and construct water vehicles which can float on the surface but not for submarines [though the principle used to drive submarine is same].
Whatever submarines used before were kind of primitive type and their success was very limited. In the year , the Englishman William Bourne developed the first working model of modern submarines. His submarine was consist of leather bags with manual adjustments to fill-in and fill-out the water inside and outside of the bags.
This was the basic principle which is used even today to submerge the submarine and bring it back to the surface. His model was able to completely submerged in the water, rowed beneath and stay underwater until oxygen lasts inside the wooden and waterproofed submarine. The basic requirements of staying underwater were eliminated in the year when Magnus Pegelius built and demonstrated the first submersible to be actually built in modern times.
In , Russia built the first modern military submarine in the ruling of Tsar Peter the Great. All credit goes to its designer Yefim Nikonov a carpenter. It was a single person, hand-powered submarine.
