According to a Global Network report, at present, in order to counter the Platon, the Taiwan military has "reinforced" the underground positions such as Jiashan and Shizishan Caves in the Central Mountains of Taiwan, built an "explosion-resistant explosion-proof wall" outside the cave, improved the power, air conditioning, ventilation, fire fighting, drainage, and other systems inside the cave, and deployed Patriot 3 anti-aircraft missiles. ”
The Taiwan military's "east coast reinforcement" plan shows that the Taiwan military finally dares to face up to the high-pressure situation brought about by the "people's liberation army's normalized cruise around the island." The Taiwan military's Hualien Jiashan Cave Reservoir System was completed in 1992, while the Shizishan reinforcement plan was implemented since 2017 and completed in 2021. The idea is to hollow out the eastern part of the Central Mountains and hide most of the advanced fighters in caves to avoid the first round of attacks and preserve combat strength. The main part of the project is to dig dozens of interconnected caves of different sizes in the Hualien Jiashan area, which can park 250 fighters. The hangar has a high degree of explosion resistance and seismic resistance, and can withstand the direct hit of 2000 pound bombs and withstand earthquakes below magnitude 7.
Relying on deep rocky mountain caves, these underground bases in eastern Taiwan are difficult to be destroyed by ordinary air-to-ground missiles and aerial bombs carried by fighters, and at this time, the chicken must be killed with a cattle knife, that is, a ground drill.
At present, the PLA's ground drill bombs are also blooming everywhere. From 100 to 1000 kg caliber aerial bombs, various air-to-ground missiles, to Dongfeng Express, to 300 mm long-range fire, there are different types of ground-penetrating warheads. For example, the Dragon 140 series long-range rockets on public display are ground-penetrating projects launched using long-range rockets, using long-range rocket technology, terminal guidance technology and semi-armor-piercing penetration technology. The ammunition is 8 meters long, the full ammunition weighs 800 kg, and the warhead weighs 150 kg
At the Zhuhai Airshow, China exhibited the "Tiange" 1,000 kg guided bomb and the YL-V601 ground drill bomb, which is the same technical level as the Gem Road III 2,000 pound ground drill bomb in the United States. Large ground drilling bombs are often processed using the barrels of retired large-caliber guns, such as the American GBU-28 "Jewel Road" III. Laser-guided ground drill bomb uses the barrel of a scrapped and sealed M11 203 mm self-propelled howitzer as the shape of the bomb shell.
The technical performance of several large-scale ground drilling bombs in China is also comparable to the GBU-28 "Jewel Road" III. laser-guided ground drilling bomb in the United States, which can be equipped with intelligent fuzes, which can penetrate 6 meters of reinforced cement fortifications and 30 meters of hard soil, and will become the standard ground drilling weapons of the Air Force in the future.
In addition, the North Industries Group has also published the live-fire target shooting footage of the "Bunker Nemesis" Cloud Arrow 1000 type 1-ton heavy ground drilling bomb, and the video footage of the J-7A flying leopard mounting and dropping the Cloud Arrow 1000-1 laser-guided bomb, which can attack and reinforce bunkers and underground facilities. This kind of ground drilling bomb is not only powerful, but also has the advantages of long range and high accuracy. The bomb weighs up to 1,000 kilograms, has the ability to penetrate 6 meters of reinforced concrete, if it is just an ordinary sand layer, the drilling ability is predicted to reach tens of meters, and the overall performance is not much worse than the MOP giant drilling bomb.
The Cloud Arrow 1000-1 is just a weapon we unveiled in 2019, and if there is no accident, the super large ground drill bomb with stronger drilling ability and greater power has long been available. As early as 2019, CCTV released a weapons test video, a bomber-6K bomber projected a large aerial bomb to bomb a solid target, from the streamlined giant bomb to the bomber hatch ratio estimated that the weight of this ground-penetrating bomb is at least five tons or more, is expected to be able to penetrate 60 thick rock layers or concrete like the American giant ground-penetrating bomb.
Drilling weapons, also known as deep penetration ammunition, refer to weapons that can penetrate deep into a solid target and detonate, and the initial penetration weapons are classified as armor-piercing bullets and semi-armor-piercing bullets. Since the beginning of the Gulf War, the United States has used more than a dozen invasion weapons, and the most powerful can even strike reinforced bunkers at a depth of 60 meters underground.
Naturally, we cannot stay out of the situation, and we have also made remarkable progress in the field of protection engineering and invasion technology, and the PLA is currently equipped with a large number of ground-penetrating weapons for the four branches of land, sea and air rockets. China's ground-penetrating bombs are also developing towards the two extremes of light and heavy.
Or it is a super big guy of five or six seven or eight tons, who can penetrate the rock formations and reinforced concrete of more than thirty or forty meters thick at once, but the price is also expensive, and it costs tens of millions of yuan.
Or it is a small and exquisite drill bomb, large length-to-diameter ratio, can be guided, very cheap, and the attack aircraft can hang more than a dozen at a time. For example, the United States and China have developed many drill-type small-diameter precision-guided bombs, most of which are low-cost small-diameter ground-penetrating bombs, of which the US-made SDB small-diameter bombs and the domestic CM-506KG aerial-guided bombs and the Feiteng-7 precision-guided bombs are typical.
The weight of these small ground drilling bombs is 110 to 150 kg, using a small size projectile body with a large aspect ratio + diamond back folding wings, using inertial navigation and satellite-assisted positioning, and the diamond back folding wings can allow the bomb to glide for 50 to 100 kilometers after being dropped at a high altitude, with the ability to throw outside the defense zone.
The bullet body of the small diameter bomb is a very slender, large-length ratio structure, equipped with a carbide armor-piercing warhead, with extremely high projectile body strength and armor-piercing depth. After the throw, a submerged trajectory at a large angle (close to 90 degree angle) over the zenith is used, the dive speed can exceed the speed of sound, the penetration ability of the solid underground target is more than the traditional 1000 kg drill armor-piercing shell, and the penetration depth of reinforced concrete is more than 1.8 meters.
For example, the U.S. military will purchase a total of 15,000 small ground-penetrating bombs between 2017 and 2025. It is speculated that the number of purchases in China will not be less.
