This is hilarious...Perhaps, the clearest militarization of space is America's new anti-missile missile program, a program not just of research but of deploying actual weapons. No matter how ineffective the existing American system is - it has failed many tests, and independent scientists advise us that the computer programming for such a system is truly beyond our existing ability - America's spending new billions on it has to make China and Russia uneasy. The same scientists and other experts warned some years back that a new American "Star Wars" program would start a new weapons race, and they were right. The Russians have already announced the development of a new warhead that spirals unpredictably when heading for its target. It also may put into service a mobile version of its highly-accurate Topple-M intercontinental missile.
If it is so obvious that it is impossible to have a missile defense, then why are the Russians and the Chinese so 'uneasy' to the point that it could lead to a new arms race? Why should the Russians bother to develop a maneuvering warhead? Unless, of course, that it is not so impossible after all to have an effective missile defense. This writer apparently does not include critical thinking in his piece.
No...China does not (yet) have a credible anti-satellite missile program. What China did with the FY-1C satellite was limited in scope. The interceptor missile was from a fixed land based platform. Some may argue that it was launched from a mobile TEL, but that still does not negate the fact that the system is limited by China's geography, unlike the US SM-3, which is ship launch capable, and the Earth is largely covered in water. So currently, for China to actually shoot down any satellite, the system must wait for the satellite to come to it.China's response includes its ability to destroy spy satellites...
Post interception debris analysis does not show any debris in a downward trajectory. This reasonably tell us that the interceptor was in a 'fast' or upward course. While this approach method is a considerable technical achievement in itself in terms of target detection and orientation, in a hypothetical shooting war between the US and China, the US could just simply ordered the satellite to change orbit slightly off a few degrees moments before the satellite break horizon over Chinese territory and that would throw the missile's intercept calculations.
Now...If post interception debris analysis does show debris in a downward trajectory, then this reasonably tell us that the interception came from a 'loft' orbit or downward course. In a 'loft' trajectory, the missile's course should take it to a higher orbit than the satellite's orbit, the missile then search for the target satellite, predict its course, then descend upon it. Since a 'loft' orbit is the higher altitude, there is more time available and any satellite maneuver will be detected and if the missile is capable, it will make appropriate corrections. Even though the 'fast' interception course is sensor demanding, a 'loft' interception is actually even more demanding in terms of sensor sophistication since now the missile must be able to distinguish the satellite from background clutter, if any, and more difficult if the target maneuvers.
While this is an impressive technical achievement by China, it is at least one generation behind the US SM-3 and past ASAT programs. The shoot down of US-193 by a ship launched SM-3 interceptor demonstrate a true 'at will' ASAT capability by the US. In a hypothetical but technically feasible scenario, if a targeted satellite is deemed sufficiently instrumental to the conflict, several Aegis cruisers can be stationed along the target's predicted orbital path. If one ship missed, the next one line can take its chance.
Most people probably forgot about the F-15 ASAT program back in the 1980s...
ASM-135 ASAT - Wikipedia, the free encyclopedia
Although any project that involved space naturally involves technical difficulties, the program was cancelled largely for financial, not technical, reasons.On 13 September 1985, Maj. Wilbert D. "Doug" Pearson, flying the "Celestial Eagle" F-15A 76-0084 launched an ASM-135 ASAT about 200 miles (322 km) west of Vandenberg Air Force Base and destroyed the Solwind P78-1 satellite flying at an altitude of 345 miles (555 km). Prior to the launch the F-15 flying at Mach 1.22 executed a 3.8g zoom climb at an angle of 65 degrees. The ASM-134 ASAT was automatically launched at 38,100 ft while the F-15 was flying at Mach .934.[7] The 30 lb (13.6 kg) MHV collided with the 2,000 lb (907 kg) Solwind P78-1 satellite at closing velocity of 15,000 mph (24,140 km/h).
There are no reasons to doubt that this method will be abandoned, unless something in the line of a 'death ray' come along. Now imagine the US fully capable of deploying ASAT systems anywhere in the world, land and/or sea, within 24hrs and it is clear that no potential adversary's satellites are safe. This and the ship launch SM-3 constitute a true 'at will' ASAT capability.The United States Air Force intended to modify 20 F-15A fighters from the 318th Fighter Intercepter Squadron based at McChord Air Force Base in the United States state of Washington and the 48th Fighter Interceptor Squadron based at Langley Air Force Base in the United States state of Virginia for the anti-satellite mission. Both squadrons had airframes modified to support the ASM-135 by the time the project was cancelled in 1988.[13]
The USAF had planned to deploy an operational force of 112 ASM-135 missiles.
