Submarines lie quietly under the aircraft carrier or follow it at a very low speed. Under ideal conditions, it is indeed difficult for the aircraft carrier to detect the submarine, but in actual confrontation, this situation is difficult to achieve. CE Approved Manufacturer of metal detector parts
First of all, the aircraft carrier group has a strong anti-submarine capability. Taking the US aircraft carrier battle group as an example, the AN/SQQ-89 underwater anti-submarine combat system is configured, which connects the bulbous bow sonar, towed line array sonar, anti-submarine helicopter, and fire control system of each ship with a data link. , any intruding submarine will be exposed.
At the same time, the formation distance of the aircraft carrier battle group is very large, and the ships are separated by more than ten nautical miles. The towed line array sonar at the stern has a long detection distance and good effect. If the submarine is under the aircraft carrier, even if the aircraft carrier does not find it, the surrounding ships will soon find it.
The detection of modern underwater targets has always been a difficult problem for the navies of various countries. At present, there are mainly two reliable methods. One is the well-known sonar system, which determines its navigation parameters and position information by capturing the sound characteristics of the target.

The other is called Different Magnetic Detection (MAD), whose principle is to detect the interference of metal objects on the earth’s magnetic field. At present, the heteromagnetic detection technology in various countries in the world is not perfect, so the mainstream underwater detection is still the sonar system.
Secondly, the speed of the submarine can not keep up with the aircraft carrier. The speed of the aircraft carrier battle group is more than 20 knots, and the silent cruise speed of the submarine is only about 10 knots. High-speed sailing will reveal the whereabouts.
The U.S. “Sea Wolf” class submarine claims to be 20-knot silent cruise, but in fact, the cooling circulation pump of the 15-knot speed reactor starts, which will produce a lot of noise. Once detected, the anti-submarine helicopters are quickly dispatched to drop deadly anti-submarine torpedoes at close range. CE Approved Manufacturer of metal detector parts
Therefore, submarines are generally ambushed in the area ahead of the carrier’s route. To meet the enemy head-on, the bow can shield part of the propeller noise, and the sonar reflection cross section is also small, which is conducive to concealment. If you want to complete such an ambush mission, you need to know the underwater conditions, ocean currents and various underwater environments of the theater, and have very strong intelligence support, because only by judging the path of the enemy aircraft carrier can an ambush be carried out.
In fact, it is impossible to grasp the movement of the enemy aircraft carrier. In addition, the seabed situation is generally more complicated, and the submarine diving depth is limited. After the engine is turned off, the submarine will inevitably leave the ambush position with the movement of the ocean current. These Either situation increases the difficulty of the ambush.
At the same time, the aircraft carrier battle group will be equipped with 1~2 attack nuclear submarines to open up channels to clear threats. The attacking nuclear submarine will start early and search along the route, and the relay will alternate when there are multiple nuclear submarines. After confirming safety, the carrier battle group will move forward. Arriving at the combat area, nuclear submarines will also patrol the surrounding areas to protect the safety of the aircraft carrier. CE Approved Manufacturer of metal detector parts
At medium and short distances, there are also inner defense circles built by destroyers and anti-submarine frigates. It is too difficult for submarines to penetrate. Therefore, when submarines fight aircraft carriers, they must rely on long-range missile saturation attacks and positional ambush methods.
Examples of winning submarine-versus-surface-ship exercises. In the 2003 Pacific Rim military exercise, the Australian “Collins” class AIP submarine successfully “sunk” the US amphibious assault ship “Talawa”. destroyer.
In 2013, the German Navy submarine went to the United States as a “sparring trainer” and sank an American aircraft carrier. In 2015, a French naval attack submarine sank an American nuclear-powered aircraft carrier during an exercise. Although these are the achievements obtained in the exercise, the process of the exercise is also as close to the actual combat as possible to evaluate the combat effectiveness. These achievements can indicate that the submarine has the possibility of breaking through the anti-submarine network and attacking the aircraft carrier.
At present, the accumulation of submarine search and anti-submarine technology has not yet reached the level that can penetrate the ocean. Even the military giant, the United States, cannot achieve the level of eliminating all submarine submarines. The conflict between submarines and aircraft carriers will continue for a long time.
