Um the pac-3 has been tested. Its results were almost flawless and is considered to be one of the best in the world. First of all the Chinese supersonic missiles will be useless without any reconaissance. Second of all China's ships won't be able to launch their missiles within range. Third of all China's missiles will be intercepted by the sm-3, ESSM, sea RAM, and phalanx. The Harpoon may not stack well against Russian or Chinese missiles on paper, but the difference in stats lies in doctrine. The US relies on its airfleet for strike power. In other words the range of the harpoon is offset by the range of the F-18. Second of all, China does not have the ability to track USN submarines. China's ASW is dismal at best.
Nor would I put too much hope in the US edge in radars. China will soon have AESA radar and you can bet that anything the US can do
China has yet to field a indigenous radar that can compare with AESA. The aegis can track over 250+ targets simotaniously supersonic or subsonic.
Flight testing of the PAC-3 missile continued with the successful intercept of a HERA TBM target during the Seeker Characterization Flight (SCF) on March 15, 1999. The primary mission objective of the SCF was to collect data to reduce risk for the DT-3 flight (and the subsequent missile flight program). Test objectives included checking target acquisition and tracking, PAC-3 missile seeker performance during a TBM engagement, and data collection/analysis of target profiling during terminal homing. The PAC-3 Overarching Integrated Product Team (OIPT) reviewed the results of the SCF and approved it as a "successful intercept." The OIPT also determined that the SCF qualified as one of the two intercepts required by Congress before LRIP funding could be obligated to contract.
DT-3 was successfully conducted on September 23, 1999. With the exception of the target reentry vehicle (RV), the design of DT-3 was identical to the SCF. The target for the SCF contained simulated chemical submunitions. The DT-3 RV was a simulated bulk chemical warhead. Data reduced and analyzed indicate the PAC-3 system tracked, engaged, intercepted and destroyed the target. Both the SCF and DT-3 were conducted with prototype hardware and software configurations and non-tactical seeker software. Additionally, the targets were not fully threat representative, since the seeker software had not matured to achieve threat level performance. However, post flight simulations using the tactical seeker software indicated a good probability of success against threat representative targets.
DT-4 was scheduled for December 1999. It was deferred, however, after pre-flight hardware-in-the-loop testing revealed an unexpected target radar cross-section return signal that the seeker software was not yet ready to accommodate. The flight test program will move on to execute DT-5 in January 2000, and DT-4 objectives will be investigated elsewhere in the flight test matrix.
The LFT&E program planned in the TEMP was revised to eliminate the sub-scale, full-body interceptor sled tests. Development of a sub-scale, full-body interceptor was cancelled in FY99. The purpose of sub-scale sled testing was to assess the contribution of the rocket motor to lethality (analyses indicate that the rocket motor will only contribute to lethality in a very small number of potential tactical intercepts). Subsequent hydrocode analyses indicated that the rocket motor makes a significant contribution to missile lethality in that small percentage of intercepts. Fourteen of fifteen full-scale sled tests against unitary and submunition chemical, high-explosive submunition, nuclear, and biological submuntion targets have been completed. The remaining test, replication of the DT-6 flight test, is planned for the spring 2000. The sub-scale light-gas gun test program, completed during FY99, produced test data at higher velocities (3 km/sec) than sled track (1.7 km/sec). The LFT&E program should be completed before the end of FY00.
