Misunderstanding: How to read the dissertation, "Can the Aegis ship deal with drone attacks?"

　On July 31, a private tanker was attacked by a self -destruction drone off the coast of Oman, which did not mean that a new form of war was born with a drone attack.

Examples of harassment attacks on private ships

　The incident is performed with the motivation to "attack with a weak power drone to avoid war, because if you attack with a powerful anti -ship missile, you will want to attack and harass."

　Although it is a rough number, it is a common figure that anti -ship missiles and torpedoes are about 200 kg of explosion, and propeller promotion self -destruction drones are about 20kg of explosion.Defeating a large ship with a suicide bomber is not destructive and destroying a small boat.

　The attacker intentionally launched a low -powered attack, and if it could be secretly attacked with an affordable explosive weapon, the rimpet mine (adsorbed bomb), which is installed with classical human hands, is also the latest.Whatever the self -destruction drone, which is an unmanned weapon, was fine.

Assumptions and conditions for drone attacks on combat ships

　It is an intention to attack a large ship tanker to attack a private ship, but has not yet been done against a large Navy combat ship.If you do it, the purpose of execution is the same harassment, or a strategy that causes full -scale military action in the gap, aiming to be unusable during the repair of the ship, and other drones as a decoy and anti -ship missile attack.There will be a tactic that combines.

　There is a report from the US Navy graduate school published in 2012 as a paper assuming a drone attack on combat ships.UAV is an abbreviation of an unmanned aircraft and a drone.

　This paper is assumed that a drone will be launched from a distance just before the Aegis ship enters the port.Therefore, the Aegis ship does not activate the anti -aircraft radar and cannot use anti -aircraft missiles or guns.Used weapons are limited to CIWS (20mm machine gun), EW jamming (radio wave obstruction), radar decoy (decoy electric wavy source), smoke bank bullets, etc. If this tied condition setting, 10 drones are simultaneous attacks.It is judged that several aircraft break through and succeed in the attack.

　In other words, this paper reports that "Aegis ships cannot cope with drone attacks", but "can surprise warships in a careless state with drones."In the past, the Aegis ship "Call" was attacked during anchored self -destruction boat attacks, but it is a warning bell that a drone attack is set up a little farther than that.

　If the Aegis ship can demonstrate all the fighting abilities off the coast, all of them will be easily beaten down, such as only 10 propeller promotion drones.

　The title is a swarm attack (a group attack), but it is not a story of a group autonomous battle with a drone with advanced artificial intelligence, but a broad sense of simply launching a large number of drones.

　Immediately before entering the port, the urban area is often near, and if the Aegis ship transmits the radio waves of a powerful electronic obstruction without concern, it will not be possible because it will have a major adverse effect on citizens' lives.The anti -aircraft radar that transmits powerful radio waves for the same reason will also enter the port after cutting the system.

CIWS is not equipment that deals with simultaneous saturation attacks alone

　The CIWS (Falcan with a 20mm Vulcan gun) has a built -in small radar and intercepts the aerial air goal automatically.This is the last shield that protects ships from enemy anti -ship missiles, which originally broke through the anti -aircraft missile.In other words, it is not the premise that CIWS alone will fight a large number of aerial goals.It is a weapon used by anti -aircraft missiles on the premise that most of the enemy goals are dropped.

　In the dissertation, it is not surprising that the conclusion that it will break through is set to confront many drones in the situation of CIWS only.

　The solution that can be solved is simply increasing the number of CIWS mounted, using an optical warning monitoring and aiming system, or using anti -aircraft weapons, or 2012.There are some ideas, such as replacing CIWS with a laser cannon whose output has been significantly enhanced than at that time, or deploying a small security ship (armed with small anti -aircraft missiles) at the port of the Aegis ship to make a drone vigilance.It floats.If you can afford it, it is easy to drove an enemy drone from the air if you wary the sky with a fighter, but it will be a burden to put out a fighter every time at a port.

"Harpy" is expensive and there is not much difference from anti -ship missiles

　There are two types of attack drones assumed by the dissertation: Harpy, an anti -radar self -destructive, and a remote -operated unmanned machine (RC UAV).Harpy is a wandering weapon that detects enemy radar waves and automatically rushes, and costs a few hundred million yen because the sensor is expensive.This is about two -thirds of anti -ship missiles, so there is not much price difference.

　Then, if you do your best and prepare a ground -to -ship missile, is it more effective than using Harpy?After all, the amount of warhead explosive is 10 times, so if a proper anti -ship missile hits, it can be severely damaged.

Even armed forces use real anti -ship missiles

　And there is actually a precedent.There are two cases in which a non -regular military armed forces have prepared ground -to -ship missiles and attacked.

　In both cases, Iran is presumed to have been used by supplying the Iranian version of the C-802 Missile Missile to armed forces.However, both the hizvola and the Fushi group are large as armed forces, so it seems that it is a battle -related battle behavior rather than a terrorist attack.

　In particular, the Fushi school has a track record of using a lot of Iranian drones, and despite the fact that the Delta wings that are very similar to Harpy have listed the results to the ground -fixing target, they are usually on anti -ship attacks.We prepared anti -ship missiles and used.It is a natural judgment that anti -ship missiles are more effective for offshore movement.

　If you use Harpy for anti -ship attacks, you will have to devise a method, such as using an anti -ship missile or using it at the same time as an anti -ship missile.However, the original application of Harpy is the crushing of ground radar, so that is given priority.

　Hanito was miraculously damaged and returned after repair, despite the fact that the hit was good or the anti -ship missile hit the stern.The "Swift" has been caused by a big wreckage and an incompetent loss, and she has been tagged by the Greek Elusis and is connected to the quay for the parts removal of the same type of ship.
