    China's Type 093G nuclear attack submarines with vertical-launch missiles are comparable to the US Virginia class submarines. Russia has yet to develop a nuclear attack submarine with vertical-launch missiles. Huludao Shipyard has completed the construction of three Type- 093 submarine |...

    China's Type 041 Yuan diesel-electric submarine with AIP is superior to the latest Russian Kalina-class submarine, which still does not have AIP.

    The Mars mission was all NASA. Show me something that India can do by itself without another country's expertise. Whoa! Your claim of copycat really scares me. Not! No one cares what you think. The world knows the Chinese supercomputer is made in China. So is everything else. ----------...

    There is a problem in your argument. You have to prove it. China has proven its deep-sea submersible can travel deeper than the best US submersible. China has proven it can send people into space. Currently, the US has to hitch a ride on the Russian Soyuz. The Chinese supercomputer is six...

    Your reasoning is flawed. The US built the first supercomputer a few decades before China. Yet, China surpassed the US in supercomputers. There is no reason that China cannot surpass the US in stealth fighters.

    The J-10B is very aerodynamic. General Dynamics had a finalized design that was very close to the J-10A. The J-10B is a 4.5 generation fighter. The RAM cockpit and DSI provide a smaller RCS. ---------- A General Dynamics early design study for the F-16 looks similar to the J-10 | Alert 5...

    You are making an assumption. Both the J-20 and F-22 are untested. Until they engage in combat, we won't know the kill ratio for each plane. It could be 1:1, 1:2, or some other ratio. There are factors that work in the J-20's favor. The J-20 is a bigger plane and has a larger radar. This is...

    Did you read the picture caption? It says China's first VHF AESA. An AESA radar can focus into a narrow beam for enhanced tracking. China has the supercomputers to amplify and detect the signal. With two units, China has a VHF AESA interferometer. It is suicide for an F-22 to venture into...

    Chinese and Russian radar experts have made the claim. US radar experts also make the same claim. The F-22 can be seen with VHF radars. Given the advances in interferometry and signal processing during the last 20 years, it is now possible to track an F-22 with VHF/UHF radar. This is common...

    China's supersonic stealth Dark Sword UCAV doesn't look anything like an American UCAV. That's a second example for you to think over. A third example is the double-fuselage low-band radar Chinese Divine Eagle drone. A fourth example is China's Sky Wing 2 stealth UAV. ---------- A fifth...

    I'm trying to tell you that you're wrong. China mastered the basics of aeronautics and the designs are Chinese. The specifications are suited for Chinese purposes. For example, the J-20 stealth fighter is optimized for transonic flight because of the long distances in the South China Sea. In...

    I have no idea what you are talking about. A Chinese fourth-generation J-10B fighter with canards and DSI has no counterpart in the Russian or American airforce. For your information, the J-10A has discontinued production. Thus, I mention the J-10B.

    China has already surpassed the US in supercomputers and high-speed trains. Surpassing the US in one field after another is a Chinese specialty. Other examples includes anti-satellite kill vehicles (when China shot down a four-foot cube in orbit) and hypersonic glide vehicles. You Indians...

    You're delusional. China has already said its anti-stealth radars can see the F-22 flying along the Korean border. It is common knowledge that the F-22 is stealthy only in X-band and upper S-band. Chinese radar interferometers and low-band radars can easily detect and track the F-22.

    The US F-22 has never engaged in combat against another stealth fighter. The only way to find out is to watch an air battle between the J-20 and the F-22. Or the F-22 vs. the Chinese J-31. Or the F-22 vs. the possible Chinese Dark Sword stealth UCAV.
