The earliest attack method used by submarines is "contact attack", that is, the use of underwater vehicles to get close to the target and destroy the target by means such as **. This type of attack carries a high level of risk and uncertainty because submarines are easy to detect and strike when they are close to the target.
With the continuous development of submarine technology, the attack methods of submarines have gradually upgraded. During the First World War, submarines began to use "non-contact attacks", that is, the use of underwater vehicles to drop torpedoes and other ** attacks on targets. This type of attack has higher accuracy and efficiency than contact attacks, but there are still certain risks and uncertainties.
During the Second World War, the attack mode of submarines was further escalated, and the "intermittent contact attack" was adopted, that is, the use of underwater vehicles to first get close to the target, and then through intermittent contact and evacuation, multiple torpedoes and other attacks were launched. This attack method can improve the accuracy and efficiency of the attack, but there are still certain risks and uncertainties.
With the continuous development of modern technology, the attack methods of submarines are also constantly escalating. Modern submarines usually use a combination of multiple attack methods to attack, including underwater vehicles, surface ships, aircraft and other platforms, and at the same time use advanced detection and identification technology to improve the accuracy and efficiency of attack.
