The landing of the army at Wonsan was a major turning point in the early stage of the Korean Peninsula War.

Compared with the Inchon landings in the 20th and 50th centuries and the Korean War, although both were amphibious landings behind enemy lines, the difference between the two is very obvious.

In order to land at Incheon, the U.S. military made a lot of preparations, taking advantage of the high tide for a few hours to send troops ashore.

The Wonsan landing was fought very "crisply," the amphibious landing became an "amphibious" landing, the main projection force was changed from a landing craft to a helicopter, and the main support force was changed from a warship to a fighter plane.

The North Korean army simply could not adapt to the pace of the US offensive.

Just 24~hours after the outbreak of the war, many North Korean troops did not even make preparations for entering the war, and the North Korean troops participating in the war were still resisting the attack from the south, and the US army opened a second battlefield behind the battle line.

The high-intensity bombardment, which lasted for several hours, completely broke the will of the defenders of Wonsan to resist.

According to US military statistics, during the bombing period, at least half of the officers and men of the three DPRK divisions stationed in Wonsan deserted, and the number of deserters exceeded 15,000.

The rout became the beginning of defeat.

Before the bombing was over, the US unmanned aircraft that took off from the amphibious assault ship arrived over the battlefield and began to guide the "Zumwalt" class destroyers in the amphibious fleet.

Iran war. Zumwalt-class destroyers performed bravely. The combat effectiveness of the 155-mm naval guns was confirmed.

In the context of the "Sino-US Cold War". The U.S. Congress not only approved the purchase of more Zumwalt-class destroyers. It also asked the Pentagon to draw up a "long-term plan for the development of the Navy." It is clearly mentioned. In addition to reducing the number of littoral warships built on the ground of the "Freedom" class. The Navy will purchase Zumwalt-class destroyers at a rate of three per year and replace all Alik-class destroyers by 2035. Based on the "Zumwalt" class hull, develop a comprehensive replacement for the "Ticonderoga" class ground air defense cruiser.

Before the outbreak of the Korean War. In total, the US military has 24 ~ "Zumwalt" class destroyers (6 of which are under construction). In addition to 1 for each aircraft carrier battle group. 6 amphibious fleets were also equipped with 1 ship each.

The Zumwalt-class destroyers are most notably capable of ground strike.

When using EGMSS (Rocket-Boosted Extender Shell). capable of striking all ground targets within a range of 1c0 nautical miles (about 185 km); When using EDD (Ultra Long Range Attack Shells). Capable of striking all targets within a range of 150 nautical miles (about 277 km); From the 22nd (under construction). It will be equipped with a 155-mm electromagnetic gun (the US military has already planned to improve the 1 ship in front of it according to the same standard). This allows it to hit ground targets at ranges of 200 nautical miles (about 370 meters); If against inland targets. Hypersonic cruise missiles with a range of 1 km or cruise missiles with a range of 25C0 km are used.

In general. The "Zumwalt" class mainly uses long-range shells to hit ground targets.

First, artillery shells are cheaper, even the most expensive EDD, the unit price is less than 50,000 US dollars, and the price of a cruise missile is at least 5 million US dollars (2 years of currency value), which is only one percent of the cruise missile; Second, the response speed of naval artillery in combat operations is faster, from receiving an order to the arrival of artillery support, it only takes 5 minutes at most, while missiles take 1c to half an hour; Third, the ammunition reserves are more sufficient, each "Zumwalt" class destroyer can carry 1155 mm shells, but can only carry a maximum of 80 (in fact, it is far from reaching, because 80 vertical launchers must be equipped with some anti-aircraft missiles, anti-ship missiles and anti-submarine rocket-booster torpedo) ground attack missiles; Fourth, the sustained combat capability of naval guns clearly exceeds that of ground-attack cruise missiles, and the 155-millimeter electric heat cannon can continue to fire at a rate of 6 pieces per minute for several hours, or at a rate of 12 guns per minute for 5 minutes, and no land-attack cruise missile on a warship can continue to strike shore targets at such a fast speed.

In the Iranian war, the three Zumwalt-class destroyers involved in the war destroyed 80 percent of the ground targets in the coastal areas with less than one percent of the input, and the combat effectiveness ratio far exceeded that of any other type of warship.

During the Wonsan landing battle, the US military put into operation 2 "Zumwalt" class destroyers.

Before the landing force went ashore, the 2 "Zumwalt" class destroyers, under the guidance of unmanned aircraft, projected nearly 1,700 shells at hundreds of targets on the shore, with a hit rate of more than 8 and a destruction rate of nearly 60 percent.

The high-intensity artillery bombardment destroyed the last line of defense of the North Korean army.

U.S. Marines flying in helicopters entered Wonsan without resistance, quickly taking control of the road leading to the port and airport.

At 2 o'clock, the marines took control of the Wonsan airfield.

A few minutes later, the first units of the 1st Air Assault Division arrived and joined the combat operation to attack the port of Wonsan. At this time, another group of troops from the 1st Air Assault Division, which arrived at the Japanese air base in the afternoon, set off for South Korea, replenished fuel on the way, and flew directly to Wonsan Airport.

Before, the U.S. military entered the port of Wonsan.

Nearly 2,000 North Korean officers and soldiers trapped in the harbor put up a desperate resistance and blew up the port

Most of the infrastructure.

Presumably, in order to avoid too heavy casualties, the US military did not rush into the port of Wonsan.

By this time, the Korean army stationed near Wonsan had completely retreated.

It's just that the U.S. military didn't expect that just a few hours late, the North Korean army would bomb Wonsan Port into ruins, leaving a mess that was difficult to clean up.

For the later ground operations, the North Korean troops guarding Wonsan Port made the greatest "contribution".

According to the plan, after the US forces occupy the port of Wonsan, they will immediately send the heavy equipment of the amphibious fleet ashore and then launch an attack on Pyongyang and Hamhung. Because the port infrastructure was blown up by the North Korean army, the U.S. military could not immediately send a large amount of heavy equipment ashore, and therefore could not immediately launch a ground offensive.

In desperation, the US military had to adjust its tactical arrangements.

The 1C11 Air Assault Division, which had previously cooperated with the 2nd Marine Division, became the main force of the attack, divided into two routes, and attacked in the direction of Pyongyang and Hamhung separately, occupying transportation hubs and important military towns along the way.

The 1st Air Assault Division was supported by carrier-based aircraft from three carrier battle groups that entered the Sea of Japan.

In order to reduce the difficulty of the attack of the 011th Air Assault Division, the US military dispatched 12B strategic bombers in the early morning to launch hundreds of air-launched cruise missiles at the North Korean military camp, air defense position, and command and communication center on the plateau north of Wonsan (the name of the town, located at the intersection of the Yuanxian Railway and the Pyeongwon Railway, the transportation hub center and the military town). Subsequently, nearly 30B-1BB bombers were dispatched to bomb the North Korean army's defensive positions, dropping hundreds of tons of bombs!

The US military dared to use strategic bombers to carry out volley bombing, first, because it completely mastered air supremacy, and second, there was no air defense threat.

These 2 massive bombardments completely collapsed the North Korean infantry divisions stationed in the plateau!

When the assault force of the 1st Air Assault Division arrived at the plateau, it captured thousands of North Korean officers and soldiers who were confused and had a complete mental breakdown. Many of these captured North Korean officers and soldiers returned to Korea after the war.

According to some people's recollections, the US military's "carpet bombing" not only destroyed the DPRK army's defensive positions, but also destroyed the DPRK's will to resist.

According to the records of the 1st Air Assault Division, a total of 3,700~ corpses of Korean officers and soldiers were buried on the plateau!

After the bombing of the plateau, the US military again dispatched strategic bombers to carry out a large-scale strategic bombing of Sinseongcheon in the northeast of Pyongyang.

It's just that the U.S. military did not continue to have good luck, and in this round of bombing, 1 B-1B was shot down by an anti-aircraft missile of the North Korean army!

Although only one bomber was lost, the US military still quickly adjusted its tactics and did not let the B-1B, a strategic bomber that was about to be decommissioned, carry out large-scale bombing missions with ordinary bombs. The B-1B is not the B-2, and the risk of using guided bombs to carry out attack missions is very high, and in addition to ordinary bombs, the best option is an air-launched cruise missile.

The problem is that at that time the US military did not have many air-launched cruise missiles in reserve.

Fortunately, the U.S. military had already sent a large number of tactical fighters to Japan at this time, and even if the B-1B could not participate in the war, it would have a great impact on air strikes.

Due to the lack of heavy equipment, the 1st Marine Division had not yet arrived, so the US Marines who landed at Wonsan did not make a sortie.

U.S. troops successfully landed at Wonsan, but failed to advance as planned.

If it drags on, the US military will not get any benefit.

In order to solve the problem, the ROK-US coalition forces temporarily changed their battle plan. The U.S. Marines who arrived at Wonsan first advanced to the south to assist the ROK and the 7th Infantry Division to annihilate the North Korean forces in Gangwon Province, allowing the ROK and the 7th Infantry Division to quickly move north and launch an attack on Pyongyang in place of the Marines.

If only the US military is on duty, the problem is not very big.

The problem is that the U.S. military must cooperate with the ROK army, and it is the ROK army, not the US military, that is the main force.

The U.S. military quickly adjusted its battle plan, but the ROK army was not able to immediately adjust its battle plan.

By the morning of the 20th, when the 7th Infantry Division, which had occupied Jinhwadi, advanced in the direction of Huaiyang and carried out the task of interspersing and dividing the battle, the ROK troops accompanying the 7th Infantry Division did not immediately follow, but stayed in Jinhua. After the Korean army set out, it did not follow the 7th Infantry Division to advance to Huaiyang, but attacked Changdo in the east according to the original plan, and advanced to the destination of Gaocheng Port!

The supporting characters rush to the front, and the protagonist loses his way.

To make matters worse, after the U.S. and South Korean forces parted ways, nearly 50,000 North Korean troops surrounded Changdo-Hwacheon-ri-Huaiyang!

In an area of less than 1 square kilometer, 50,000 Korean troops gathered!

Not to mention 50,000 soldiers, even if it is 50,000 civilians, if they rush out, the ground flank of the South Korean and US coalition forces will be threatened.

Fortunately, the US commander discovered the "wrong" action of the ROK army in time, and immediately concentrated air power to attack the North Korean troops who were trying to break through the encirclement, so that the ROK army immediately turned around.

At this point, it was noticeably late to adjust the direction of the attack.

The South Korean and American forces had to adjust their battle plan again, first annihilating the besieged 50,000 North Korean troops.

Obviously, the operation of the South Korean and American forces in Gangwon Province did not go well, but compared to the battle in the direction of Kaesong, this little trouble is nothing.

Damn it**

During the closure period, every half an hour, the flickering brothers went crazy together, so that everyone was happy!
