The blow was swift and violent. 【】

The trajectory of the electromagnetic cannon shell is completely different from that of the traditional artillery, and when hitting distant targets, the elevation angle of the electromagnetic cannon is between 60 and 85 degrees, and the larger the elevation angle, the longer the firing range.

The shell with a diameter of 155 mm (completely unrelated to the caliber of conventional artillery) and weighing 185 kg flew out of the "muzzle" at a speed of 2,200 meters per second (about 6 Hz), and after reaching the "apex of the trajectory" at 125 kilometers, it entered the "mid-gliding trajectory", and the "ballistic correction system" consisting of a satellite navigation system and a laser gyroscope began to work, controlling 72 "miniature course correction rocket engines" located around the aerodynamic center of the missile body (which coincided with the center of gravity). Adjust the flight trajectory of the projectile according to the preset ballistic data.

Because the "mid-course ballistics", which account for more than 75% of the total range, are in outer space, where the air is very rare, the range of the shells can reach an astonishing 185 kilometers. All ultra-long-range guns, including the electrothermochemical cannons on Zumwalt-class destroyers, were designed to maximize the ballistic altitude in the middle section and reduce the distance of the shells at the bottom of the atmosphere.

At a distance of kilometers from the target, the shell begins to dive and enters the "terminal trajectory". In the case of an ordinary artillery shell (in fact, it is still a guided projectile, only there is no end guidance system), the terminal trajectory is still controlled by the "ballistic correction system"; In the case of guided shells, the flight trajectory is corrected by the guidance system and control system.

The radius of circular probable deviation of DP-11A using ordinary shells is 1/50,000 of the firing range, and at a range of 185 kilometers, there is a 50% chance that the shell will fall within a circle centered on the target with a radius of 37 meters; When using guided projectiles, the accuracy is from 5 to 1C meters, depending on the difference in the guidance system.

The 185-kilogram ordinary shell had a charge of 35 kilograms and a radius of destruction against semi-hard targets such as bunkers of 25 meters. From this it can be calculated that it takes 1 shell to destroy 5 ground targets. The cost of an ordinary artillery shell is only 15,000 yuan, and the launch cost is less than 1C yuan, while the value of the cheapest air-to-surface missile is more than one million yuan. There is no doubt that the "effectiveness ratio" of naval guns is much better than that of missiles.

Compared to artillery of the same "caliber", electromagnetic cannon shells are much heavier.

For example, the shell weight of a 155-mm howitzer is generally between kilograms and 75 kilograms, and the charge does not exceed 15 kilograms, and there are even only a few thousand grams.

In the final stage of the attack, the naval artillery shells dived down from an altitude of more than 100 kilometers, and the landing speed was about Mach 0.

The greater charge and the huge amount of kinetic energy gave the naval artillery shells greater power. When dealing with underground targets. A longer delay in detonation time can be set. Enables the shells to penetrate several meters of soil. Destroy underground fortifications.

It also has a high rate of fire due to the power of the naval guns.

1 DP-1A is capable of throwing 5 kg of ammunition in 8880 minutes. An army long-range artillery battery of 12 155mm howitzers can only throw 8,100 kg of ammunition in five minutes. Counting the power of naval artillery shells, the power of army howitzer shells is several times greater. The ground strike capability of 1 DP-11A solid ground target is roughly equivalent to that of 2 artillery batteries.

In total, there were DP-3A on 1 battleship. Equivalent to 8 batteries of long-range artillery!

In just 5 minutes. 3 battleships threw nearly 45 ammunition at the positions of the South Korean army at Jeju airfield!

Such a huge amount of ammunition thrown. If it is done by aviation ground fighters. It is necessary to put in 1 brigade of 24 fighters each carrying gram-class aerial bombs.

Another advantage of naval artillery firepower is that it is highly persistent.

After 5 minutes of rapid shelling, 8 shells fell every minute, destroying 3 bunkers or firing points on ROK positions.

If the same strike missions are performed by aviation, then fighters need to be thrown into combat at a rate of 2 bells 1 aircraft.

Even without taking into account the fuel consumed by fighters and the risks of performing battlefield support missions, the sustained strike capability of aviation is still inferior to that of "artillery".

While the support fleet was shelling the ROK positions to the fullest, the officers and men of the 15211th Battalion, which was the first to land in the air, were busy clearing the airborne landing site.

According to the operational plan drawn up by the General Staff, the airborne 152 did not participate in the battle exclusively in an "airborne" manner.

The 15211th Battalion, which was the first to be airborne, had two tasks, one was to clear the landing ground near Jeju Airport and provide a site for the second batch of 1522nd Battalion to be airborne, and the other was to capture Jeju Airport, eliminate the airport garrison, clear the airfield runway, and welcome the transport planes carrying combat troops and war materials.

It is also said that the main forces of the airborne 152 will "land" on Jeju Island in the form of "airborne".

The efficiency and safety of airborne landing far exceed that of airborne, and many heavy equipment can only be airborne, not airborne.

The capture of Jeju airfield became the first task of the airborne 152.

In order to contain the ROK forces in the vicinity, the 15211th Battalion landed near Jeju Airport, and the 1526th Battalion, which was responsible for the covering mission, landed near Hanlim, cutting off the ground access of the main ROK forces deployed in Musepo and Sinchang-ri to Jeju and completing the task of dividing the campaign.

The actions of the 1526th battalion were critical.

The ROK army has always believed that it was the Republic of Nations Marines who were the first to "land". In addition to Seongsanpo in the east, the most suitable landing spot on Jeju Island is Museppo in the southwest.

The Marines could first capture Gapo Island, south of Museppo, and deploy artillery on the island before landing on Jeju Island. To this end, Han

The forces were deployed to the Republic of Marines who landed at the landing of the Republic of China about 1 meter away from the Mussepur and the Sinchang Rifu about 1 meter away from the Mussip.

Who would have thought that the first to arrive was the Airborne Forces.

Before the arrival of the main forces of the Airborne 152, the main forces of the South Korean army had to be blocked south of Hanlim and the security of the Jeju airfield must be ensured.

The actions of the 15211th battalion were even more important, and the sooner the airfield was captured, the sooner the main forces could arrive.

At 9:15, the artillery bombardment of the support fleet was still going on, and the vanguard of the 15211th battalion began to advance towards the airfield.

Although there was only one company of troops, Guan Shangxun transferred the airborne combat vehicles of the other company to form an "armored sharp knife".

A total of more than 3C airborne combat vehicles, which should definitely not be underestimated!

For the ROK garrison without armor, the airborne combat vehicles equipped with 30 mm machine guns and anti-tank missiles (anti-tank missiles are often used against fortifications when attacking defensive positions, and the effect is very good) and can block 1277 mm machine gun bullets fired from 200 meters away are veritable "armored knives".

Zang Jiayu also led the whole squad of soldiers to participate in the offensive operation, but they did not directly attack the positions of the South Korean army.

Guan Shangxun has received the news that the reconnaissance platoon transport plane has made a mistake in the airborne landing location and dropped the reconnaissance platoon of the 15211th battalion to Hanlin! Although Guan Shangxun had ordered the reconnaissance platoon to rush over as soon as possible, for a while, he could still only let Zang Jiayu's infantry squad carry out the fire guidance work.

Anyway, Zang Jiayu and others did a good job.

The attack on the airfield must be done quickly.

If the ROK army reacts and destroys the infrastructure of the airport, even if the airborne troops occupy the airport, they will not be able to use the airport effectively.

At 9:30, after cleaning up the airborne field, Guan Shangxun threw himself into the second company.

By this time, the transport group carrying the 1522nd battalion had already reached the sky over the airborne landing site.

In order to prevent the 1522nd Battalion from sharing the fruits of victory, after the first batch of troops of the 1522nd Battalion landed, Guan Shangxun handed over the defense of the airborne site to the 1522nd Battalion, and personally led the other troops of the 15211th Battalion into the offensive battle.

The battle for the assault on the airfield was fierce, but not tragic.

At 9:55, the 15211th Battalion occupied the airport tower and captured 1 colonel of the ROK Army.

At this time, Guan Shangxun figured out that there were only 2 infantry battalions guarding the airport, and there were several defense lines distributed around the airport, which could not stop the airborne troops at all.

At 0:00, Guan Shangxun gave the signal to occupy the airport.

The transport planes of the 15211th and 1526th battalions have returned to the ground air base in the northeast region, and after receiving the news from the 15211th battalion, all the transport planes took off with the maximum load.

In addition to the 1523rd Battalion, the first to be transported was a "mobile fusion power supply system".

The system was not intended for the Airborne Forces, which were not equipped with electric combat vehicles, but for transport aircraft that arrived one after another. The Y-14 has a range of less than 2,500 kilometers at its maximum load, while Jeju Airport is 65 meters from the nearest air base in the Republic mainland and 1,200 kilometers from the air base in the Northeast region.

At 0:15, after the Airborne Forces took control of the defensive positions around the airfield, the support fleet stopped shelling.

About 20 minutes later, the support fleet began to provide artillery support to the 1526th battalion. To be precise, to provide in-depth fire support for the Airborne Forces. The target of the shelling was not the South Korean army in the vicinity of Hanlin, but the main force of the South Korean army, which was assembling in Sinchang-ri and Mussepo.

At 0:50, the carrier-based aviation began to carry out the task of "blocking in depth", focusing on bombing the main forces of the South Korean army.

It can be said that this is a battle without much suspense.

Lacking air cover, no armor, and no artillery support, it is difficult for South Korean infantry to defeat airborne troops with air support, artillery support, and airborne combat vehicles in frontal combat. Even if the conditions of the two sides are equal, it is difficult for ordinary infantry to defeat the airborne troops, known as the "king of infantry", in a frontal battle.

At 11:55, the first Y-15 aircraft carrying power supply equipment landed at Jeju Airport.

For the officers and men of the Airborne 152, how to maximize the efficiency of the use of the airfield is more important than how to defeat the South Korean army.

Jeju Airport does not have a high throughput capacity, and in the past, it was mainly used by commercial aircraft transporting passengers. Even if the General Staff sends "professional" aviation coordinators, they can only guarantee that one transport plane will take off and land every hour due to various factors such as site area, infrastructure, and personnel work efficiency.

Even so, the strength of the Airborne Forces is growing at a breakneck pace.

In order to improve the efficiency of airlifting, Xiang Linghui made adjustments to the airlift platoon at noon and sent the equipment and materials needed for the construction of the engineering battalion and the construction of the field airfield to Jeju in advance, delaying the delivery time of the airborne troops.

Beginning on the afternoon of the 7th, the engineering corps built a field airfield south of Jeju.

The ROK troops, which had been heavily bombarded and shelled, accelerated their counterattack and strengthened their counterattack force.

The South Korean army began to race against time, because as long as the airborne troops of the Republic gained a firm foothold in their positions, not to mention the South Korean infantry, even the American armored troops were helpless!
