After the outbreak of the Russian-Ukrainian conflict, both sides have dispatched a large number of air forces to fight, because the size of the Ukrainian Air Force is much lower than the Russian Air Force, and the performance of the Ukrainian Air Force fighter is lagging behind the Russian Air Force as a whole, so today, nearly two years after the war, the Ukrainian Air Force, which has suffered heavy losses, has rarely been dispatched, and the Russian Air Force due to the large number of fighters and can continue to produce and replenish, so although there are also large war losses on the field, it can still launch a large-scale air strike, for Ukraine, the only means that can effectively counter the Russian Air Force is the ground air defense system。 
Su-34 fighter-bomber Before the outbreak of the Russian-Ukrainian conflict, the main air defense system of the Ukrainian army was a Soviet-made air defense system, and after the outbreak of the conflict, the West provided a large number of anti-aircraft missile support to Ukraine, in addition to the "Stinger" such individual air defense missiles, the United States, Germany and the Netherlands also jointly provided Ukraine with 5 "Patriot" air defense missile batteries, although only 5 "Patriot" companies can not cover all the airspace of Ukraine around the clock, but these "Patriots" The arrival of air defense systems is undoubtedly a great threat to the Russian Air Force, which a few days ago was again planted in the hands of "Patriot" missiles!
Patriot air defense system According to a report by the global network, the Ukrainian army carefully organized an "ambush" operation a few days ago, using the covertly deployed "Patriot" air defense system to shoot down 3 Russian Air Force Su-34 fighter-bombers in one day!At that time, the Su-34 group of the Russian Air Force was carrying out a ground strike mission on the banks of the Dnieper River, and as a long-range air defense system, the Patriot anti-aircraft missile was not suitable for deployment to the front line, but some analysts believed that the Ukrainian army may have quietly deployed the "Patriot" to the vicinity of the Dnieper River at that time, which caught the Russian army by surprise!
In fact, this is not the first time that the Ukrainian army's "Patriot" air defense system has achieved major results, in May 2023, the Ukrainian army directly and secretly deployed the "Patriot" air defense system near the Chernihiv region on the Russian border, shooting down a number of Russian military aircraft, including Su-35 and Mi-8***!The "Patriot" in the hands of the Ukrainian army has repeatedly achieved major results, and in addition to the outstanding air defense tactics of the Ukrainian army, it also has a lot to do with the performance of the "Patriot" air defense system itself. In previous operations, the Ukrainian army used PAC-3 CRI interceptor missiles, indicating that the Ukrainian army currently has a newer model of the "Patriot-3" air defense system. 
The maximum range of the Su-34 pilot parachuting "Patriot" air defense system is about 160 kilometers, and the maximum interception distance when performing anti-missile operations is 20 kilometers, compared with long-range air defense systems such as S-400 and Hongqi-9, the range of "Patriot" is not outstanding, but the air defense system has strong anti-saturation attack capabilities, high search speed and tracking capabilities, short system reaction time, high strike accuracy, and can effectively resist electronic attacks. Deployed to the front line for ambushes, it also shows the excellent mobility and deployment capabilities of this air defense system. 
At present, the Taiwan military has about nine "Patriot" companies equipped with about 580 interceptor missiles, and these nine "Patriot" companies are sufficient to cover the entire airspace of Taiwan Island, and at the same time, this is also the most advanced air defense system in the hands of the Taiwan military. One point we need to pay attention to is that these US-made air defense systems may have the ability to integrate with the entire US military combat system, and we cannot completely rule out the possibility that the Taiwan military's "Patriot" air defense system can receive air information provided by the US military in wartime, so in a possible conflict in the Taiwan Strait, the Taiwan military's "Patriot" missiles must be firmly suppressed and must not be allowed to pose a threat to the PLA's air power!
The People's Liberation Army (PLA) has an advanced modern combat system at the Patriot air defense missile launch site of the Taiwan army, which includes the key link of efficiently suppressing the opponent's air defense systemIn response to these "Patriot" air defense systems of the Taiwan military, the PLA has three major countermeasures, the first of which is electromagnetic suppressionAlthough the "Patriot" air defense system has a strong electronic countermeasure capability, launching a powerful electromagnetic attack on it can reduce its detection sensitivity and interception distance, and the PLA is equipped with advanced electronic warfare aircraft, including the J-16D, which can effectively compress the combat effectiveness of the "Patriot" after deploying powerful electromagnetic suppression. 
Secondly, the J-16D electronic warfare aircraft relies on the entire combat reconnaissance system to comprehensively keep an eye on the deployment position of the "Patriot" air defense system, including its fixed launch position and the temporary launch position after taking mobile deployment, as long as it grasps the traces of the "Patriot" air defense system, it can launch tactical ballistic missiles, cruise missiles, and hypersonic missiles to launch a saturation attack on it!In addition, a large number of reconnaissance and combat drones can be launched into the air in wartime to combat patrols over the entire theater of operations, and once the traces of the "Patriot" air defense system are discovered, they can immediately launch an attack to destroy them. 
The J-10 fighter with anti-radiation missiles on it is, of course, the various long-range anti-radiation missiles installed by the PLA are also sharp weapons against the "Patriots."The "Patriot" air defense system in the hands of the Taiwan military will not have much room for survival and combat in front of the PLA in wartime.
