Well im no computer expert but i know 14mhz compared to 3000mhz is a lot more processing power, I think this is the only way raw processing power is measured. increased processing power is what programs our computers. What in your opinoin would be needed to increasing the processing speed of the missile?
You said in this thread somewhere that a MRBM travels at mach three and a ICBM travels at mach 7. the Brahmos is a mach 3 missile is is roughly comparable in the need of processing power. The brahmos is also different because with its sensors it will also manuver to the target which will also need more processing power and other missiles like the moskit also have that capability.
The minuteman warheads use GPS, not just inertial guidance, earlier versions also used stellar/inertial guidance. BTW, you're talking about US missiles not Chinese.
According to FAS it uses inertial guidance only while i couldn't find plans where it would be fitting GPS to it. But i was wrong off the mark it was 100m max with a improved inertial guidance system. But thats what you get for getting it off your head.
The actual test was conducted with a D-15A which has a CEP of 30~50m. If you think about a explosion and the distance a bullet can go 30~50m CEP is not bad for that type of situation. Imagine a massive claymore mine attached to the top of a 1 ton warhead filled with tungsten pellets. Massive circle
The missile has an accuracy of 300 m CEP for older models and 30-45 m CEP for the newer GPS upgraded systems. The missile is 9.1 m in length with a diameter of 1.0 m and a launch weight of 6,200 kg.

IRBM and SRBM are the same?. Yes i was reading the links posted before. But i highly doubt the missiles the US were thinking about were more than scub missiles or enlarged scud missiles without any countermeasures but bumb missiles which fly in a strait path that dont have flares or anything else
The very earliest the Chinese could possibly deploy a ASBM is 2009, providing they can actually build enough surveillance assets.
While china has two spy sateillies up and half a dozen ELINT AWACS in building and testing. Like i said before it states in the chinese white paper that a system has been tested already and thats where the conclusion about ASBM comes from.
What KH satellites have to do with this, I have no idea, maybe you'd care to elaborate.

These planes would be detected well before detecting the carrier, considering the US would have her carrier based airborne radar planes up, increasing the US fleets radar covergae out to hundred of miles.

Well the Isaeli harpy anti-radiation UAV is for attacking ground targets only and are useless against planes.
The FT-2000 may seem impressive, but an E-2 Hawkeye or E-3 AWACS radar has a far greater range than the missile and would probobly never come into range from the SAM variant. The same applies to an aircraft launched version, they attacking aircraft would be spotted well before coming into range.
Also with ARM's, an easy way to defeat them is to turn all your emitters off.
Also, the fact that the CHinese are only offereing it for export doesn't seem to imply that they have that much confidence in the system.

ORIEguy,
This is not just ment to send one or a couple of SRBM or MRBMs to attack a carrier fleet its about flooding the defenses combined with air lanuched anti-ship missiles and submarine lanuched anti-ship missiles. The russians in the cold war would hook up their backfires with mach three kitchens to saturate the US carrier defense which were meant to be effective
chinas doctrime is a little similar to the saturating bit but doing that with stealthy missile attacks. Chinas purchases of Kilo submarines with the Klub cruise missile system. china has 12 of them right now. 2 877 and the rest 636 ones armed with the klub system. and producing the Song class with chinese missiles with about one dozen in service or sea trials. But im not saying all of them will be concentrated on a carrier group but the figure of 24 modern submarines kind of hits you in the face pretty hard
The surface fleet is the soverny class with moskit missiles. the first ones 956 has the 120km moskit missiles and the improved 956EM has the improved moskit with a range of about 200km. Plus chinas own destroyers with 280km range YJ-62 missiles and a lot of other missiles but i cant be bother going over all of them at this momment.
Chinas air component is the Su-30MK2 which is a Su-30MKK optimized for naval combat with the N001VEP radar firing KP-31 missiles. Fly low and fly fast to the target. Chinas JH-7/A fighters which are purpose built for naval strikes along with ground strikes but anyway was built to go low and fire their missiles. then there are the the H-6 missiles which are also being equiped with cruise missiles. old but still flying
Anyway what im getting at is china is not going to just throw some missiles at them and hpe the problem goes away but a co-ordinated assult involing all arms of chinas military. Most probaly chinas submarines will fire the first shots then all of a sudden a hail of pellets come from the sky then some low flying aircraft. all assuming america enters within 200km of chinas coast or first interfers in the taiwan strait
-------------
Bottom line is chinas SRBM or MRBM will be fitted with improved guidence to allow them to see and hit a moving carrier. Its been tried and called a "sucess" according to a chinese white paper about chinas military moderizationa and effects on the region by the authors of "unresticted warfare"

OK seriously while that's a right nice doctrine you've looked up, we're analyzing the adaptability of ballistic missiles to maritime attack.
You have to understand that somehow, you're going to have a way for these systems to search for ground based targets actively in order to guarantee a real warhead kill. Forget the battle group defenses, it's going to be hard enough to hit the damn things.

The fact you need a RV limits you in many ways.
First, the payload has to be large enough to be shielded for reentry.
Second, it will need sensors.
Third, you need to be able to guide the RV into the target, which is a time/sensor/processor problem.
Fourth, you need to achieve a saturation effect(multiple targets).
Solve problem 3 by slowing the payload down. OK, that works. Parachutes, and all, been there done that.
Move on to problem 4, which you can solve by using submunitions which get dumped out after slow down. Except that doesn't work since a large RV that's slow is a sitting duck for interception by SAMs.
So let's make the submunitions release early on.
Again, no go. You hit problem 1, which requires shielding, which requires size.
Already, this concept is not looking to healthy, and we haven't even gotten into sensors yet.
A mass bomblet saturation would work well against even the most sophisticated AEGIS-like systems. The issue is getting the bomblets to the target. And ballistic systems are obviously not the ideal solution. Stealthy high flying units have a much better chance at getting to the target.
If you can knock the battle group blind, you've gone from suicide attack to excellent chance of success.
Why waste all those military assets? Don't forget that there also electronic solutions to radar guided missiles. We have yet to properly see how those factor into this equation. And the picture already is pretty ugly for an attacking force as long as AEGIS+SM-2+ESSM is up and running. That's an absolute asston of missiles that are locked cocked and ready to shoot down inbounds.

also note china has already mastered stearing a re-entry vehicle as demonstrated by some of its ballistic missiles and it already posses iskander(CEP of 20-30m) and SCUD-D(CEP of 50m) and the iskander can hit moving targets. it doesnt really need much modifications to the design to ge it to hit aircraft carriers. all it would really need is sub-launched capability and you could technically fire it from a submarine at ships/aircraft carriers.
An inertial guidance system would probably give an accuracy of 200 m CEP while inertial coupled with either a Global Positioning Satellite (GPS) equivalent system would provide about 50 m CEP. The use of the inertial navigation, GPS and optical correlation provides an accuracy of 10 to 30 m CEP

It has a high degree of accuarcy only when using American GPS guidance. In any time of war you can expect the US to block Chinese GPS usage in theater.
I would hate to think how vulnerable Chinese aircraft would be, if they had to search for the US fleet.
4 electro-optical and 4 radar sats to have effective coverage.
A system has been tested already ? I can find no information on this. Have a link.

I think they were refering to a GPS system not the american GPS system. Whilst china has the choice of GLONASS instead of GPS china still is not commited to GLONASS simply because GLONASS is not reliable as well as the russians and two china does not use foriegn GPS systems on any of its important systems. espically a ballistic missile in the taiwan strait.
All systems china is using is connected to the BeiDou-1 of 2 sateillites. I highlighted 2 on purpose because that is all that is needed for a regional system to have the asia region covered. GPS is only 24 because it covers the globe while china does not yet need that capability and only needs two for its military requirements.
Chinas coastal systems have a range of more than 400km while chinas airborne AWACS and AEW would have more than the 200+km search range of the N001VEP radar. so if the US is planning on helping taiwan it would need to be at least near the area because the longer you are the less sorties you are going to make.
Chinese aircraft would in no way be venuble because they will detect a superhornet hundreds of kilometres away if this system is comparable to the A50I which is 80s technology which it is no using hence the different confiruratioin. It would also have patrol aircraft and wouldn't be flying around by itself. These aircraft could paint targets with their radars and wait for other systems to come along
4 electro-optical and 4 radar sats to have effective coverage.
Sounds a little overkill to me. For a dumb bast warhead just being within your CEP would be just fine and having all these system wouldn't be needed since the aim is not for pin-point accuracy but only get within your CEP.

No link but its somewhere in china-defense or centurychina forums. This was published at least half a year ago on chiense forums. Im still wondering why this is still such a hot issue. Beats me really, since i thought most people would have read it.

As you can see, thismaccuracy you talk about is primarily due to the US GPS sytems, which China wouldn't hvae access to in time of war.
As for putting them on submarines, they'd be even less accurate, mainly due to the position of the submarine wouldn't be known accurately without GPS, not to mention Chinese subs are notoriously noisy.
The Extended Range Active Missile (ERAM), tentatively designated SM-6, will add an extended range, overland cruise missile defense capability. The Navy's recommended strategy, based on a market analysis, is to pursue a sole-source acquisition through Raytheon Missile Systems. This low-risk approach relying on Non-Developmental Items will support an FY 2010 IOC. This approach will utilize the existing production active seeker from AMRAAM Phase III, utilize the existing production airframe from the Standard Missile-2 Block IV, leverage multi-service investments in future technology growth path, and leverage existing production infrastructures and workforces.
A robust extended range (ER) anti-air missile with engage-on-remote capability is key to providing flexible firepower throughout the battle space using a variety of targeting platforms. To that end, we are developing the Extended Range Active Missile (ERAM), which uses an SM-2 Block IV propulsion stack with an active Advanced Medium Range Air-to-Air Missile (AMRAAM) seeker to provide enhanced capabilities. ERAM is an active missile that can use the full kinematic capability of the missile to greatly expand the battlespace. ERAM will leverage the significant investment made by the Defense Department in the AMRAAM seeker.
ERAM is the evolution of the Extended Range Standard Missile airframe and propulsion stack into an active seeker TAMD interceptor with the ability to engage on remote tracks not held on the firing ship’s radar or covered by the firing ship’s fire control illuminators.
