Taiwan is a treasure island in our country. It has been our territory since ancient times. In ancient times, Taiwan was called " Ryukyu ". It is recorded in history books that there is a hidden tunnel on this island that runs through the central mountain range of . Moreover, the construction of this tunnel took ten years and cost nearly billions of yuan. This tunnel is actually an air force base in Taiwan. So why is this base hidden in the mountains? What is its unique use?

Taiwan is located in the southeast coastal area of ​​China, across the Taiwan Strait in the west, facing Fujian Province, adjacent to the East China Sea in the north, and the Pacific Ocean in the east. The capital is Taipei City. In history, Taiwan has been renamed many times. During the Han Dynasty and the Three Kingdoms, it was called Yizhou , and later Liuqiu. It was Xiaoliuqiu until the Ming Dynasty. It was officially renamed Taiwan and belonged to Fujian Province.

There are two air force bases hidden in the central mountain range, one is the Jiashan base in Hualien, and the other is the Zhihang base in Taitung County . The reason why Taiwan spent a lot of manpower, material resources and financial resources to build these two bases was related to the international situation at that time. In the 1970s, Nixon visited China and announced the establishment of diplomatic relations with China. However, before that, the United States had established diplomatic relations with Taiwan, but Taiwan was just a region. If the United States had always had connections with Taiwan, it would be a provocation of China on the surface, so the United States broke off diplomatic relations with Taiwan at that time.

without the protection of the United States, and it is easy for China to take back Taiwan, our country's inherent territory, so Taiwan came up with a solution to hollow out the eastern part of the Central Mountains and hide a large number of advanced aircraft in order to preserve firepower. Because the western part of Taiwan is full of plains, it is obviously difficult to defend, and Taiwan is small in area and does not have enough strategic places. In addition, my country has the ability to strike missile , so Taiwan finally decided to build an air force base in Hualien County east of the Central Mountains.

Hualien County is located in the eastern part of Taiwan, facing Taitung in the south. It is the largest county in Taiwan. It is the Central Mountain Range to the west. The Central Mountain Range traverses north and south of Taiwan. The eastern terrain is steep and steep because it is protected by mountains, and the eastern part of Hualien County is the Pacific Ocean, which can be said to be an easy to defend and difficult to attack. In the 1980s, Taiwan decided to implement the drilling plan here.

Another air force base is also in this plan. Taitung County is located in the southeast of Taiwan Province, with an area of ​​3,515 square kilometers. It is the third largest county, second only to Hualien County and Gaotou County. The southwest is the Central Mountain Range and the east is the Coast Mountain Range . It has the protection of two mountains. The air force base is built here to hide and easy to guard.

This drilling plan is called "Jian'an No. 3". It was built in the 1980s and was not officially completed until the 1990s. It cost more than NT$40 billion, which is converted into about 9.2 billion yuan. Although the idea of ​​Jiashan Base is to hollow out the central mountain range, it is a mountain range after all, and the rocks are hard and the project is huge. We cannot know from the outside whether it is hollowed out.

Zhihang Base is an air force base invested and built in the implementation of the Jiashan Base Plan. It is located in the south of Jiashan Base, and the two are not far apart. However, Zhihang Base is smaller than Jiashan Base, with only three large hangars inside. However, Jiashan Base has more than a dozen caves of all sizes, and it can accommodate up to 250 fighter jets. It is a very advantageous strategic base. Unfortunately, it can only be used to store fighter jets in Taiwan.

In order to facilitate the takeoff of the fighter jets, the Hualien base also built a 2,500-meter-long aircraft runway, which is connected to Hualien Airport . Because of the importance of this base, Taiwan has also built an air defense missile base nearby. In fact, the main function of these two bases is defense, and attack is second.

Taiwan Air Force 's main airports are all deployed along the western line of Taiwan Province. When war comes, the opportunity to fight starts from the original airport. If the western airport is attacked, they will fly to the Hualien base and Zhihang base to land. In terms of attack, Jiashan base is in the north, echoing the Hualien port Navy, Zhihang base is in the south, echoing the Pingtung Military Port . Therefore, these two bases can attack and retreat or defend, but their greater function is defense.

It is obvious from the map that Taiwan’s intentions are visible. The Navy Port, Air Force Airport and Jiashan Base are connected to one line and rely on each other on offense and defense. Moreover, Jiashan and Zhihang Base are both located in the middle section of eastern Taiwan. It is convenient to support both south and north. Hualien is also a stop on the Taiwan Roundabout Railway.

Although these two bases are easy to defend and difficult to attack, there is a fatal problem with Jiashan Base, that is, once the 2,500-meter aircraft runway outside it is blown up, all the fighter planes will be useless. In order to solve this problem, Taiwan extended its magic claws to the expressway. It wants to build a highway from the Suao section of Beiyi Expressway, pass through the Central Mountains, and pass through the expressway on the east side of Jiashan Base. Although environmental protection groups on the island repeatedly opposed it, Taiwan Province insisted on this. Whether it can be completed in the end depends on the subsequent development of the project.
