According to global network reports, the US Navy has just made a decision on the punishment of the Seawolf-class nuclear submarine Connecticut in the South China Sea collision incident, on the grounds of "losing confidence", dismissed the "Connecticut" nuclear submarine captain, deputy captain and sailor captain of the three leading personnel.
The captain of the USS Connecticut, Lieutenant Colonel Mellen Algilani, the deputy captain, Major Patrick Kahin, and the captain of the mariner, Cory Rogers, were relieved of their duties. The commanders of the first, second, and third were all killed, indicating that the human factor in the submarine collision incident was very large, and it was likely that there were more serious wrong instructions and insufficiently thorough judgments.
However, the U.S. 7th Fleet is still secretive about the damage to the Seawolf-class nuclear submarines, saying only that the submarines hit seamounts on the seabed and damaged the ballast tanks. According to a growing number of revelations, the submarine may have crashed during a deep diving voyage in the South China Sea, ramming the slope of an undersea mountain with its bow, and once sitting on an unknown submarine mountain range in the South China Sea.
Aaron Amik, a well-known American military media person and submarine warfare expert, believes that through the comparison of satellite photos, the bow of the Connecticut nuclear submarine is likely to be hit and damaged very badly.
The violent impact caused damage to the sonar cabin in the bow, as was the submarine's front ballast compartment at the rear of the sonar cabin, which meant that the entire front part of the boat needed to be replaced. The San Francisco nuclear submarine, which last crashed in 2005, was also damaged by the front ballast compartment, and the decommissioned "Honolulu" nuclear submarine had to remove the bow parts and install it on the "San Francisco".
The Seawolf class is more tragic, there are only three, there is no replacement at all, restart the construction of a new bow, the amount of work is too large.
After analysis, many US media believe that the damage to this nuclear submarine is so serious that it may be so serious that it has to be decommissioned early. It was also suggested that the submarine be scrapped and dismantled as spare parts for two other Seawolf-class nuclear submarines. This also shows how badly damaged the boat is.
The dismissal of the commander of the ship No. 1, 23 indicates that the impact incident was human error. "This could have been prevented from happening if there had been good judgment, prudent decision-making, and compliance with procedures for navigation planning, implementation of observation teams, and risk management," the U.S. military said. ”
Well, let's make a bold inference about this sentence:
Can this be the case, this Seawolf-class nuclear submarine is secretly diving in the eastern waters of the Paracels, in order to track China's ballistic missile nuclear submarines. The original design of the Seawolf-class attack nuclear submarine was to rely on its excellent low-noise stealth performance to quietly break into the Soviet Union's high-latitude sea fortress area and track and lock in the Soviet strategic nuclear submarine. The Seawolf class is characterized by deep diving and strong firepower, with a maximum diving depth of 600 meters.
The eastern sea area of Xisha is the most important sea area for China's high monitoring and vigilance, and this sea area is the sea area with bullets on duty of China's strategic nuclear submarines, which is commonly known as the "fortress sea area", where there is a fierce underwater struggle.
For U.S. nuclear submarines, the eastern waters of the Paracels are high-threat seas with high combat readiness, and they must not float, cannot open navigation sonar, and cannot float irregularly to correct the error of the inertial navigation system with GPS positioning, so they cannot release communication buoys at a shallow depth close to the sea surface. Since pure inertial navigation systems have the disadvantage that navigation error increases over time, inertial navigation will accumulate errors over time.
Although the better performance of the laser inertial navigation system will be used on advanced nuclear submarines, and its drift rate is the lowest, as low as 0.01 km / h, but after the longer the mission time, the navigation drift rate will also increase. For days of pure inertial navigation without external correction, the positioning error may reach several kilometers.
The submarine then has to perform complex underwater maneuvers to evade tracking by our anti-submarine aircraft and underwater submarines. The U.S. Navy's nuclear submarine warfare manual once described the captain of a nuclear submarine with maneuvering tactics to get rid of the enemy's anti-submarine search: "If the enemy's submarine search system is aware of you, it is not a big deal." You can still confuse the other party by constantly changing the course and depth, the amplitude of the action should be larger, the steering must be greater than 20 degrees, and when changing the depth, you should jump up and down the jump layer, and the speed should be kept within the amplitude of 5 knots, so that it is difficult for the other party to lock you. ”
As a result, the US nuclear submarine had to rely entirely on the nautical chart to silently carry out a long-term secret dive of complex maneuvers with a depth of hundreds of meters under the water of the Paracels.
Doing so is bound to cause serious drift errors in the submarine's inertial navigation system, as long as the navigation error is one or two nautical miles or a few nautical miles, then the pig can hit the tree, oh no, the submarine hit the mountain...
