Submarines, hidden killers! In particular, the nuclear submarine should be very advanced, including its detection system, but the so-called world's most advanced Seawolf-class nuclear-powered submarine, the Connecticut, actually hit an underwater unknown object in the international waters of the South China Sea, and caused more than 30 submarine injuries, and the entire submarine's head was opened.
So what exactly did connecticut hit? Experts believe that the largest possibility is to collide with an underwater unmanned submersible, because the unmanned submersible is smaller and the consequences of the accident are less severe.
What objects do submarines collide with underwater?
If the submarine sails in shallow waters of about 40 meters, it may collide with large merchant ships with deep drafts, etc. "Targets with water depths greater than 40 meters may be reefs, submarines and unmanned vehicles." This collision was not a simple problem, and the captain and deputy captain of the submarine were quickly dismissed.
This is not the first time that a submarine has hit an unidentified object, and there have been many similar accidents around the world. The collision of the Japanese Maritime Self-Defense Force's "Soryu" submarine with a large civilian cargo ship in Hong Kong, China, has been said by many to be that Japanese submarines are not good, but in fact this is too naïve to say.
If because of this matter, we post articles everywhere saying that Japanese submarines are not good, then it seems that personal intelligence is not enough.
According to media reports, the Japanese "Canglong" was floating from the latent state at that time, did not start to detect the radar, used the periscope mode, did not want to float when it crashed into the freighter in the channel, resulting in three people slightly injured, the submarine on the "communication means all destroyed."
This incident allows us to see that it is not that Japanese submarines cannot do it, but because the detection radar of the roller ship is too poor, and the performance of Japanese submarines is excellent.
This is not the first time in history that nuclear submarine collisions have occurred, and we look at the 2009 British and French nuclear submarine collisions. At that time, the French nuclear submarine Triumph, a 138-meter-long nuclear submarine, was on its way back to the base, and the active sonar system had been shut down, leaving only the passive sonar system open.
The Active Sonar system of the British Avantgarde was also shut down, leaving only the Passive Sonar system in operation. The biggest problem with passive sonar systems is that when the other party (especially those with hidden means) approaches, the passive sonar system can hardly detect it.
When the collision between the two sides occurred, everyone knew after 3 days comparing the time that it was a submarine collision.
Because the French Ministry of Defense publicly reported that the French nuclear submarine Triumph collided with "a sinking object" at the bottom of the deep sea, and when asked what exactly happened to the collision, the spokesman of the French Ministry of Defense said that "it is likely to be a container".
The British military was shocked to hear a public report from the French Ministry of Defence – the Royal Navy's main nuclear submarine, the Avant-Garde, also suffered a deep-sea collision at the same time of the accident reported by the French.
why? Because neither side has an active radar system, and both sides are too advanced to detect each other, not to mention the large cargo ship that the Japanese submarine collided with this time, the cargo ship is not capable of detecting advanced submarines.
On June 9, 1931, the submarine Poseidon was sailing 20 nautical miles from Weihaiwei. At that time, the British submarine was blocked by the thick fog, and the "Poseidon" submarine collided head-on with a Chinese coal ship, and the huge impact smashed the command platform of the "Poseidon" submarine, while the submarine was still slowly overturning, and the sea water poured wildly along the gap in the hull.
After the impact, 31 crew members successfully jumped into the sea and were rescued by the dinghy dropped by the coal carrier, 16 people died on the spot after the impact, and 8 survivors successfully escaped to the torpedo cabin at the front of the submarine, temporarily saving a small life.
It can be seen that the submarine is loaded on the cargo ship, not because the submarine is not good, but the cargo ship's detection ability is weak, which also puts forward a new problem for the anti-submarine of the wartime cargo ship or the national transport force.
The number one submarine ace of World War II, he is the German submarine U-99 submarine captain Otto Krezimer, he alone sank 11 cargo ships in a month, his total record is to sink 46 merchant ships, the total tonnage of 273043 tons, ranking first among all German captains, known as the "king of tonnage",
During World War II, Germany had 1,188 U-boats in service, sinking 395 Allied ships, more than 5,500 transport ships, and killing 45,000 people and counting the number of supplies. In November 1942 alone, U-boats sank 118 Allied ships, setting a record for sinking a total of 743321 tons in a month, inflicting unbearable losses on the Allies.
The armored this time is the Japanese "Soryu" submarine, manufactured by the Kobe factory under the Japanese Kawasaki Heavy Industries, is the first boat of the Japanese Maritime Self-Defense Force's cutting-edge "Kuraryu" class submarine, with a length of 84 meters, a width of 9.1 meters, a standard displacement of 2950 tons, an underwater displacement of 3500 tons, and a follow-up boat increase of 4280 tons, which is the world's largest AIP-powered submarine.
The hull is made of a strong material of "high tension steel", with 2 sets of diesel-powered turbines, and 4 groups of Stirling closed-cycle propulsion turbines, using a single-shaft seven-blade high-curvature propeller, with a maximum floating speed of 13 knots, an underwater diving speed of 20 knots, and a crew of 65 people.
The 11 "Soryu" class AIP submarines equipped by the Japan Maritime Self-Defense Force have a standard diving depth of 500 meters, which is very rare in conventional submarines, and its maximum diving depth is 800 meters.
The diving depth and silent performance of the "Canglong" class are very excellent, and the concealment performance under the water is excellent, so the combat performance of the "Canglong" class AIP submarine can never be underestimated, and this collision puts forward higher requirements for our anti-submarine operations.
China's peace comes from not easy, and in the past China, the aggression we suffered has also come from the sea many times, this time the US and Japanese submarines have run rampant in the surrounding waters, once again giving us a warning, forget the war will be dangerous! - Anti-submarine is very important!
