The origin of the rapid-fire close-range anti-cannon
The United States is making a joke again. Their high-tech weapon GDM-008 rapid-fire close-range anti-cannon has been surpassed by the domestic 1130 close-range anti-cannon . Let’s start with this weapon of the United States. Since then, in the early days of the Cold War , aircraft and ships equipped with anti-ship missiles have gradually emerged in naval battles. Therefore, when the navy faced the threat of such military weapons, it urgently needed a weapon for defense, and CIWS came into being. , and close-in defense artillery is one of them, and it is also the most widely used type. This type of artillery is generally small-caliber and has a high rate of fire. It is installed together or separately to form fire coverage. Its own computer is added with radar Aiming at the target, it can shoot down aircraft or missiles in just a few seconds. In order to ensure the rate of fire, revolving cannons and revolving tube cannons, also called Gatling cannons, are commonly used. This type of weapon can be said to be the most important weapon in modern warfare. One of the fastest fire rates.
Fighter manufacturers can also produce the close-in defense gun
GDM-008 Millennium close-in defense gun. This is a multi-purpose close-in defense gun jointly developed by Germany and Switzerland in the late 1990s. It can not only be used for The warship performs close-range air defense missions and is also equipped with a variety of ground combat air defense missions, which can effectively attack threats from the sea or the air. The contractor of DM-008 is Lockheed Martin, referred to as Lockheed Martin . Here we will give Let’s make a digression. Lockheed Martin is one of the largest fighter jet manufacturers in the world. In the aviation field, it controls all the production and launch of military satellites in the United States. It is also the main manufacturer of inter-continental missiles in the United States and plays an important role in strategic missile defense. It has also made outstanding achievements in the system field, including the anti-tank missile and airborne electronic equipment. This shows that Lockheed Martin has innate advantages in military weapons and manufacturing.
The material and data of the close-in defense gun
The Millennium Weapon System passed the test of the US Navy on May 4, 2005. The first user was The Royal Danish Navy , equipped in the country's Absalon class On the multi-functional support ship, the Millennium turret weighs 3.8 tons, is 5.5 meters long, 2.39 meters wide, and 1.94 meters high. The turret can rotate 360 degrees horizontally, with a horizontal rotation rate of 120 degrees per second, and a gun body pitch range of -15- 85 degrees, with a pitch rate of 70 degrees per second. The turret has a simple structure and is made of fiberglass. It only takes 30 minutes to install. There is a battery in the turret. Even if the power supply is interrupted, the running tower can still complete multiple shots. In order to save costs , the Millennium close-in defense artillery follows the manufacturing technology of the Sky Shield land-based anti-artillery developed by Oligo, especially the 35mm artillery system, which adopts the Oligo rotating-bore 35mm fast running, with an effective range of 3500m, and the bomb bay adopts The wheel-type design without an ammunition chain can prepare 252 rounds of ammunition at one time, and can continuously shoot 8-12 times at air targets or 20-30 times at water targets. Ammunition consumption depends on the attack target, and Millennium can also choose from three types. The rate of fire can reach up to 1000 rounds per minute.
Domestic 1130 close-range anti-cannon advanced capabilities
Although the Millennium Weapon System has only one barrel, it still has a very excellent rate of fire through multi-bore technology. In addition, it also has 35mm large-caliber shells, which are more destructive. The outside of the gun barrel is equipped with a sheath that can reduce radar detection, which greatly increases the stealth. It is also equipped with an advanced control system. It can not only receive combat instructions from warships, but also conduct close-range air defense operations alone. WG is also in this field. The leader, WG's HPJ11 11-barrel 30mm gun is the world's most powerful rapid-fire gun . The 11 barrels can fire 11,000 shells per minute, reaching the highest in the world. This means that there will be 166 shells per second. It can effectively intercept anti-ship missiles with speeds up to four times the speed of sound. Targets flying towards it will be blown into pieces. The 1130 type close-in defense gun has the latest radar and fire control system . It is highly automated and can lock 48 targets at the same time. The effective defense range is the same as that of the Millennium close-in defense gun of the same caliber, close to 5 kilometers, and the interception hit rate has reached 97%.
is currently the only close-in missile in the world capable of intercepting Mach 4 anti-ship missiles. The anti-weapon system is something that other countries' close-in defense weapons cannot achieve, but its magazine reserve is only 1,200 rounds, which can only be used for 8 seconds, which is not enough in actual combat.
Domestic 1130 close-in defense gun attack method
In fact, the gun uses burst fire instead of strafing. In order to effectively save shells and better respond to incoming targets, so as to intercept more shells, judging from a single interception, it cannot be fired. How much? The 1130 close-in defense gun has three rate of fire gears. In actual combat, different shooting modes are selected according to different targets. According to actual combat, it may only take a few tenths of a second to fire at one time, and the number of shells fired is only 100. After all, not all of them can be fired every time. After finishing the battle, you have to leave room for the next time. Its overall performance is better than the old and American Phalanx . It is currently one of the best ship-based close-in defense guns. The 1130 close-in defense gun is currently widely used on our country’s aircraft carriers, 052D The destroyer is already on the 054A frigate, which is the last line of defense for WG in the face of air threats. It is enough to intercept anti-ship missiles at the last moment.
In order to increase the destructive power, the 1130 close-in defense gun uses expensive centerless armor-piercing projectiles, using tungsten gold Made of tungsten metal, it not only has high density but also has good hardness. In addition, the flight is relatively stable and the ballistic trajectory is straight. It is basically not affected by the sea breeze. Moreover, tungsten metal has very good heat resistance. Even under high-speed close-range anti-gun fire, the resulting The heat will not deform tungsten, thereby affecting the shooting accuracy. It is a good material for making armor-piercing projectiles.
Domestic 1130 Application Channel
It has good armor-piercing ability. At the same time, the cost is also quite expensive, and modern anti-ship missiles Flight express delivery generally exceeds Mach 0.85. The supersonic anti-ship missile is the current mainstream development and can reach 3 times the speed of sound. If the close-in defense gun wants to intercept supersonic anti-ship missiles, it needs to increase the firing rate to 8,000 rounds. / minute or more, otherwise it will be difficult to intercept. If the anti-ship missile cannot be destroyed quickly, the debris formed will also cause damage to the ship due to its inertia. Therefore, the best way is to blow up the target one kilometer away. This is There are relatively high requirements for close-in defense artillery, as well as the selection of shells. Then some people will ask whether
close-in defense missiles can replace close-in defense artillery. At present, the mainstream large surface attack ships in the world have begun to enter the era of close-in defense missiles. The interception of close-in defense missiles is better than that of close-in defense artillery. From the original full close-in defense artillery, it has gradually changed to a defense mode that combines the two.
From this point, it is not difficult to see that
close-in defense missiles may also replace the interception of
close-in defense artillery. Capability
The current range of close-in defense artillery is generally about 3 kilometers. This distance is only a few seconds for ultra-high-speed anti-ship missiles. If only one missile attacks, it is enough to deal with it, but when multiple missiles attack, it is very large. The probability cannot be intercepted independently, and the range of close-in defense artillery is generally about 10 kilometers, which means that it has an interception time of about 14 seconds.
is far beyond the interception range of close-in defense artillery. In layman's terms, the interception of close-in defense artillery is to rely on the pile of shells. A defensive wall, if the incoming target cannot be hit, it can be said that our ship will be blown up. The close-in defense missile uses the guidance mode. When the target attacks,
will automatically track and intercept the incoming target. The goal is a point-to-point defense mode. The interception distance and interception efficiency are greatly improved compared to close-in defense artillery. As for the interception cost, artillery shells are definitely much lower than missiles. If it cannot be stopped, it will cost hundreds of millions. At the cost, as the last line of defense on a ship, close-in defense guns are also an indispensable part, so close-in defense guns and close-in defense missiles complement each other, both to protect warships and enhance combat effectiveness
