Hartford U.S. nuclear submarine hit the bottom of tower split

3 20 March, the U.S. Navy’s Fifth Fleet under the” Hartford “nuclear submarine and the” New Orleans ” amphibious transport dock ship in the waters of the Strait of Hormuz collision, the accident resulted in 15 crew members on the submarine suffered minor injuries, transport ships diesel leak. Fortunately, the submarine’s nuclear propulsion plant was not damaged, the accident nor the waters of the Strait of Hormuz shipping a major impact.

fresh, submarine hit their own transport ships

Under normal circumstances, different countries, warships, merchant vessels the probability of collision is relatively high. However, the Navy’s own internal collision like this thing or the first time, let alone in the world’s most powerful and most sophisticated U.S. Navy body, leaving the outside world puzzled.

Although the Navy did not specify the specific time of the incident, but the Fifth Fleet spokesman said the collision of submarines and warships are deployed in the region in accordance with established security tasks, the two collided The ships were all in the implementation of “maritime security operations.”

“Hartford” was a “Los Angeles” class submarine, the U.S. Navy’s fifth-generation attack submarine, is the world’s largest one-volume nuclear submarine construction. The boat has an excellent overall performance, is mainly responsible for anti-submarine, anti-ship, land attack missions. The “New Orleans number” amphibious transport dock ship is the “San Antonio” class dock landing ship of the second ship, the ship can carry 360 sailors and 700 Marines.

the face of this incredible collision, the American people very shocked, and many users even think that the U.S. Navy’s strength is waning. Some also quipped: “Now the U.S. waters of the whale to be careful.” And to point the finger at Obama, “cut defense spending” will.

the accident, or human factors

Interestingly, this is the second year, a nuclear submarine collision. Earlier this year, has British and French nuclear submarines in the Atlantic, “intimate contact.” And in the same area in 2007, the U.S. nuclear submarine had collided with a Japanese ship.

after the incident, although the military struggling to play down the impact of the incident, but the outside world for the cause of the collision or the extensive speculation. As of now, though, said the so-called blind spot detection, and complexity of floating sea irregularities that said so. But in fact, improper command is still the most fundamental cause of such accidents.

Under normal circumstances, each type of submarine accidents are unique with their own reasons. Can be divided into two kinds: one is the hull structure and technical reasons. Structure and technical reasons in submarine design and manufacturing process produces, such as the low level of design tend to make the submarine on the smooth, mobility and structural strength is not enough, or antiknock, and poor fire performance. Build boats in the sub-requirements, materials, technology and other tests, will be leaving the troubles, leading to serious accidents.

the other is in the sailing conditions and emergency situations arise reasons. Sailing conditions, accidents, mostly the crew of the submarine’s performance enough to grasp, or trade area of ??hydro-meteorological and hydrographic conditions are not well understood and so on. Department of boat accidents on this professional quality is not high, such as not good to use detection means, the boat is not proficient in speaking skills or lack of experience in operating the boat.

Among these, the most terrible responsibility for negligence. Such accidents often occur with the crew poor sense of responsibility, negligence, careless, or even the illegal operation.

2001 In February, the United States, “Greenville” attack submarines to Japan, “Ehime” No. fisheries training vessel sank, is not required before the implementation of floating sea observation result. In response to the collision, the U.S. military Lexington Institute researcher Roland Thomas also expressed his views, he believes that such incidents are too unusual, “you have to think that the captain of a ship which may have to bear the major responsibility. “

non-wartime submarine accident,” killer “and more

Navy submarine is one of the main branches, with a strong assault force, long-term hidden in the sea to fight the enemy important strategic sea lines of communication and onshore facilities posing a great threat. But the submarine has a fatal weakness, mainly reserve buoyancy is small, weak anti-Shen, complex and difficult to manipulate. Coupled with the main activities in the underwater submarine, the living environment is very dangerous.

submarine as a weapon have been 200 years of history, but since the first emerged on the ill-fated submarine, its history has been full of tragic accidents and disasters.

submarine nature of the incident and a variety of reasons, including fires and explosions, collisions at sea, water, stranded, and a storm.

submarine fire and explosion accident at most, the loss is often very serious. According to incomplete statistics, nearly 30 years, 136 nuclear submarines from various types of major accidents, including fires from the explosion reached 37, which led to the sinking had six, accounting for half of the total nuclear submarine sank.

the submarine, the collisions can be fatal. Submarines at sea after the war caused the collision because a lot of tragedy, the sinking of the submarine accident, the collision sank more than 20%. Among these are collision between ships and the surface, but also the collision between the submarine. Some of the crew of negligence liability reasons, some due to natural conditions.

submarine accident at all, water accidents are more common, mainly refers to water from the hatch, snorkel and torpedo tubes and a variety of irrigation valves, joint leakage and so on. And whether it is an explosion or collision, the end result will lead to water.

addition, stranded, bottom, and a storm caused damage and the sinking of the accident also often occur.

non-nuclear submarine accident of war should not be overlooked

non-wartime submarine accidents tend to give a wrong impression that it is caused by the war’s consequences were not serious consequences, but the facts and make the case.

half a century, many countries in the context of technological progress, have begun to study the possibility of weapons of attack submarines. However, this process is always fraught with danger and mistakes. Early submarine faces many potential dangers. Submarine gas and battery acid leakage, accidental torpedo explosion and crash killed thousands of sailors the world lives.

during World War II, most countries have committed to build larger, better performance, more lethal submarines. Many countries sought to expand their fleet have been conducting various types of submarine experiments, however, created more submarine accident.

After the war, due to the development of nuclear submarine era been a huge boost. Nuclear submarine full of endless activities for the possibility of nuclear submarines in the ocean’s mysterious depths of any shuttle. However, any nuclear submarine sank is catastrophic accident, because they produce radioactive contamination to marine life could have caused irreparable damage.

information gathered from the current, although the incidence of such accidents is not high, but the damage is very serious.

1961 in June, the Soviet Union “K-19″ number of ballistic missile nuclear submarine reactor cooling system pipe burst damage, the crew, the full repair, resulting in two patients died of acute radiation sickness. August 1985, the Soviet Union “K-431″ number of cruise missile submarines in the dock when troubleshooting misuse within the reactor caused by an explosion, resulting in more than 10 people were killed, environmental pollution, serious damage to the hull.

Currently, a total of six nuclear submarines lie on the ocean depths. Part of the mysterious disappearance of the deep water in the ocean, its nuclear reactors and missiles also will always be with plants as partners. Although some scientists claim that the sinking of the submarine will not pose a threat to the environment, because most of the submarine are “lying” the depths of 5000 meters in the ocean below. But some people still think that, with the sea growing number of nuclear reactors and nuclear missiles, the possibility of pollution in the world’s oceans rising.

general, to this year’s collision of two nuclear submarines from harm is not serious. But the problem is, we do not always so lucky. Especially when the submarine accident, the officers and men of the theoretical level and the actual level of training is the decisive factor in whether the risk-averse.

From this perspective, positive prevention is fundamental to ensure the submarine equipment is in good condition is a prerequisite, and the ability to command submarines and long self-help training saved the day is “critical.” (Sun Ye Fei)
