in the context of the increasingly tense situation in the taiwan strait, many military observers have begun to discuss: the gap in military technology and comprehensive strength between the two countries, and if a war breaks out in the taiwan strait. faced with this situation, many people expressed their doubts: how big is the power gap between china and the united states? if a war breaks out in the taiwan strait, can our country use high technology to seize the island?

although china has made tremendous progress in the economic, technological and military fields in recent years, there are still some gaps compared with the united states. however, this does not mean that china is at an absolute disadvantage.

from the perspective of military expenditure, the united states' defense budget has long ranked first in the world. its defense budget will reach about 800 billion u.s. dollars in 2024, while china's military expenditure is about 225 billion u.s. dollars. although the total is far lower than that of the united states, the growth rate is significant, and resources are focused on technology research and development and weapons and equipment modernization.

the united states remains the most powerful military force in the world with its strong economic strength and global military presence. after all, the u.s. navy has 11 aircraft carriers and the air force has a large number of fifth-generation fighters f-22 and f-35. these advanced weapons and equipment enable the united states to maintain strategic advantages on a global scale.

however, china has made remarkable achievements in equipment modernization in recent years. china already has the largest navy in the world, including aircraft carriers such as the liaoning, shandong, and the soon-to-be commissioned fujian.

at the same time, china's fifth-generation stealth fighter j-20 is gradually entering service and is deployed in large numbers in coastal areas. in addition, china's breakthroughs in hypersonic weapons, unmanned combat systems, anti-ship ballistic missiles and other fields have also given china the ability to deter u.s. aircraft carrier battle groups.

although there is still a gap between china and the united states in terms of overall military expenditure, china has narrowed the technological gap with the united states in key areas through optimal allocation of resources.

in terms of technological innovation, the united states has a powerful military-industrial complex and the world's leading technology companies, promoting the military application of cutting-edge technologies such as artificial intelligence, quantum computing, and advanced sensors.

for example, the united states' "gerald ford" class aircraft carriers and "zumwalt" class destroyers are representatives of high-tech weapon platforms, equipped with a new generation of electromagnetic catapult systems, laser weapons, etc.

however, china has also accelerated its catch-up in the field of military science and technology in recent years, especially in emerging fields such as artificial intelligence, cyber warfare, and unmanned systems. china's military-industrial enterprises, such as avic and china electronics technology group, are promoting the militarized application of a large number of cutting-edge technologies through the military-civilian integration strategy.

china’s hypersonic missile dongfeng-17 and anti-satellite weapon systems are considered important tools to deal with us aircraft carriers and satellite networks. in addition, china's beidou navigation system has global coverage, enhancing the military's combat capabilities, especially in complex battlefield environments, and can effectively deal with gps dependence issues.

china and the united states have different priorities in their military systems. the u.s. military system pays more attention to global projection capabilities. its military bases are spread all over the world and can respond quickly to global crises. china's military power is more focused on regional defense, especially in surrounding areas such as the taiwan strait and south china sea, and has deployed powerful "anti-access/area denial" capabilities (a2/ad) to restrict the freedom of action of the us military.

therefore, although the united states has greater advantages globally, china's military system is more targeted in specific areas, such as the taiwan strait.

therefore, if a war breaks out in the taiwan strait, the battle to seize the island will become a key task. china's preparations in this field not only rely on traditional force projection and landing operations, but also rely on emerging high-tech combat methods.

with the advancement of science and technology, the form of modern warfare is undergoing fundamental changes, and the method of island seizure operations has also changed from direct landing in the past to multi-dimensional three-dimensional operations.

in the modern battle to seize the island, high-tech weapons will play a vital role.

the first is information warfare and cyber warfare. china has vigorously developed its cyber warfare capabilities in recent years. by attacking enemy command and control systems and destroying communication networks, it can effectively weaken the enemy's response capabilities.

in addition, electronic warfare is also an important means for china to seize islands. by using electronic jamming systems, china can weaken the effectiveness of enemy radar detection and missile defense systems and gain a tactical advantage for its own forces.

secondly, unmanned combat systems will become the "vanguard force" in the battle to seize the island.

in recent years, china has made breakthrough progress in the fields of drones, unmanned ships, and unmanned submarines.

for example, china's "attack-11" drone has stealth performance and can conduct long-term reconnaissance and strike missions, providing important intelligence support to ground forces.

in addition, drone swarm tactics may also come into play in island seizing operations. a large number of drones can weaken enemy defenses and destroy key enemy facilities through saturation attacks.

furthermore, hypersonic weapons and long-range strike capabilities are also important elements in china’s battle to seize islands.

china's dongfeng-17 hypersonic missile has ultra-fast speed and powerful maneuverability. it can break through the enemy's air defense system and carry out precise strikes on important targets at sea and on land. this long-range strike capability can severely damage enemy command centers and defense facilities at the beginning of a war, clearing obstacles for subsequent landing operations.

although china has strong capabilities in high-tech island seizure operations, it still faces some challenges.

the first is the complexity of the geographical environment. the sea conditions in the taiwan strait are complex and the island terrain is rugged, which makes traditional landing operations more difficult. for this reason, china needs to rely on modern landing equipment such as amphibious assault ships and hovercrafts, as well as aerial vertical landing forces to achieve rapid mission to seize key areas.

secondly, u.s. military intervention is the biggest external challenge china faces in seizing the island. the united states has made it clear on the taiwan strait issue that it will maintain its "defense commitment" to taiwan and may intervene through military forces such as the seventh fleet. however, china's "anti-access/area denial" strategy is aimed at this point, aiming to limit the ability of the us military to enter the taiwan strait area by attacking its aircraft carrier battle groups and forward bases.
