    Can US stop Chinese DF-21D ASBM or YJ-18 ASCM? No.

    I'm referring to the new Chinese Mars mission. I think China is using its own heavy-lift rocket for the next attempt. China's satellite on the Russian rocket was indigenous. China has its own well-proven rockets. It was simply more affordable to piggy-back onto an existing Russian rocket launch...

    Can US stop Chinese DF-21D ASBM or YJ-18 ASCM? No.

    China has proceeded cautiously with Its truly indigenous Mars project. 1. NASA has decades of experience sending probes to Mars. China has none. China has to proceed slowly to avoid failure. This means slowly thinking about every aspect of a Mars mission. 2. A Chinese Mars mission is very...

    Can US stop Chinese DF-21D ASBM or YJ-18 ASCM? No.

    No. Mars orbit was NASA's experience and equipment (ie. VLBI communication). India was a mere spectator. That was not an Indian accomplishment. India lacked a VLBI network at the time. The largest Indian radio telescope communication dish was too small.

    Can US stop Chinese DF-21D ASBM or YJ-18 ASCM? No.

    You claim India's DRDO has a GPS receiver with an accuracy of 5 meters. Did you read the Nature article on China's second-generation Beidou 2 GPS satellite? The Chinese Beidou 2 has an accuracy of 0.1 meter. Which one do you think is more accurate? A Chinese Beidou 2 military-grade GPS signal...

    Can US stop Chinese DF-21D ASBM or YJ-18 ASCM? No.

    I have no idea what you are talking about. India neither has its own GPS satellites nor military-grade GPS accuracy. Some of you Indians are making the absurd claim that Indian missiles have CEP equal to China's. That's not possible without a satellite constellation like China's Beidou 2 and...

    Can US stop Chinese DF-21D ASBM or YJ-18 ASCM? No.

    You didn't address my point. China launched its own Beidou GPS navigational satellite constellation with military-grade 0.1 meter (or 10 centimeter) accuracy. Since India does not have its own military-grade GPS satellite network, how can Indian missiles possibly have CEP equal to China's...

    Can US stop Chinese DF-21D ASBM or YJ-18 ASCM? No.

    There is no way an Indian missile has CEP close to China's. China has its own Beidou GPS navigational guidance. The military has access to military-grade Beidou accuracy. Since India doesn't have its own GPS satellite system, it can only use severely-downgraded civilian GPS signals. ----------...

    Can US stop Chinese DF-21D ASBM or YJ-18 ASCM? No.

    The YJ-18 has a liquid-fuel main turbojet engine. I think the terminal-stage ramjet is liquid-fueled. To leave the missile canister, I think it has a small solid-fuel rocket booster. I think the YJ-12 uses liquid fuel for its main engine. See Deagel citation below. YJ-12 ARM | Deagel

    Typical Indian boast. No proof. No pictures. No reputable Western source.

    Can US stop Chinese DF-21D ASBM or YJ-18 ASCM? No.

    Can you show me a picture from a reputable western source to PROVE your claim about Indian ballistic missiles? My source was from Australia Air Power and the picture showed numerous Chinese missile warhead strikes. The Australia Air Power picture had coordinates of the Chinese test location...

    Can US stop Chinese DF-21D ASBM or YJ-18 ASCM? No.

    China's earlier-model DF-15C SRBM (short-range ballistic missile) has a CEP of 30-50 meters. China's DF-15C SRBM was unveiled in 2007. It has a CEP (circular error probable) of 30-50 meters. Ten years have passed. We expect the Chinese DF-21D ASBM to have improved technology and a CEP of 30...

    Can US stop Chinese DF-21D ASBM or YJ-18 ASCM? No.

    It has an automated seeker to guide the munition to the target. The onboard sensor fuzed computer is programmed to look for tanks, APCs, and trucks on its own. Similarly, the Chinese DF-21D ASBM is programmed with carriers and destroyers as targets. It does not require a human being to control...

    Can US stop Chinese DF-21D ASBM or YJ-18 ASCM? No.

    There is no need for continuous human control. The Chinese DF-21D onboard computer system will seek and destroy the target after re-entry. For example, China has developed sensor fuzed weapons. They seek a target autonomously. The DF-21D or sensor-fuzed weapon only has to be in the proximity...

    Can US stop Chinese DF-21D ASBM or YJ-18 ASCM? No.

    You can't be that dumb. What do you think rotates the gun? A mechanical platform. I don't care that the gun is electromagnetic. I'm saying the huge heavy gun needs a mechanical platform to aim it. When the incoming warhead is Mach 3 (e.g. Chinese YJ-18 ASCM) or Mach 4 (e.g. Chinese CM-400AKG...

    A railgun is a massive mechanical device. It is too heavy to aim at an incoming warhead within the few seconds available.

    Can US stop Chinese DF-21D ASBM or YJ-18 ASCM? No.

    The DF-21D warhead is only 600kg or 1,300 pounds. It carries less explosive than a 2,000 pound bomb. The crater size looks about right. An explosion at ground-level deflects most of the blast upwards. Thus, the crater looks small. When it impacts against the deck of a ship, it will rip a giant...

    Can US stop Chinese DF-21D ASBM or YJ-18 ASCM? No.

    Your timeline is wrong. Dec. 2010: Admiral Locklear says China's DF-21D ASBM has reached IOC. April 2013: Pentagon says China's DF-21D ASBM has been deployed opposite Taiwan. When I first wrote a post about China's DF-21D ASBM, it had been in development for 13 years. Today, the total...

    Can US stop Chinese DF-21D ASBM or YJ-18 ASCM? No.

    China is not going to show you the real-world tests on a moving ship. Such disclosure would reveal the terminal flight characteristics of the DF-21D ASBM. The land-based tests are the most that we will see. However, my point stands. It is erroneous to claim China has not conducted sea-based...
