"'The focus of our [US] rhetoric is North Korea,' said Steven Hildreth, a missile-defense expert with the Congressional Research Service, an advisory arm of Congress. 'The reality is that we're also looking longer term at the elephant in the room, which is China.' * * * Mr Hildreth of the Congressional Research Service said the U.S. was 'laying the foundations' for a regionwide missile defense system that would combine US ballistic missile defenses with those of regional powers, particularly Japan, South Korea and Australia.
"The Pentagon is particularly concerned about the growing imbalance of power across the Taiwan Strait. China has been developing advanced ballistic missiles and antiship ballistic missiles that could target US naval forces in the region.
"The proposed X-Band arc would allow the US to not only cover all of North Korea, but to peer deeper into China, say current and former U.S. officials. 'Physics is physics,' a senior US official said. 'You're either blocking North Korea and China or you're not blocking either of them.'
"Jeffrey Lewis, director of the East Asia nonproliferation program at the Monterey Institute of International Studies in California, said any missile-defense deployments in the Asian theater will alarm the Chinese, particular if they believe the systems are designed to cover Taiwan. 'If you're putting one in southern Japan and one in the Philippines, you're sort of bracketing Taiwan,' Mr Lewis said. 'So it does look like you're making sure that you can put a missile defense cap over the Taiwanese.'

page 10: "The Surveillance Radar Program (SRP), based on a modernized AN/FPS-115 UHF-band missile early-warning
phased array radar design, will provide Taiwan with an autonomous, long-range (3,000-km) detection,
tracking and cueing capability against ballistic missile and shorter-range (<200-km) low-elevation (airbreathing)
threats, including low flying, low cross-section CMs [cruise missiles]."
p 44: "AN/FPS-115 Radar A long-range, phased array, Land-Based Fixed Defense Radar (LBFDR) designed to detect and characterize
ballistic missiles. The radar system is capable of detecting and monitoring a great number of targets consistent
with a massive attack. The system must rapidly discriminate between vehicle types, calculating their launch
and impact points in addition to the scheduling, data processing and communications requirements. The
operation is entirely automatic, requiring operators only for monitoring, maintenance and as a final check on
the validity of warnings."
