Japan needs more powerful radar to deal with Nork nukes

Reuters:

Japan is worried the United States has so far declined to arm it with a powerful new radar, arguing the decision makes the U.S. missile defense system it plans to install much less capable of countering a growing North Korean threat, three sources said.

Japan wants to have a land-based version of the Aegis ballistic missile defense (BMD) system operational by 2023 as a new layer of defense to help counter North Korea’s missile advances.

Yet, without the new powerful radar, known as Spy-6, Japan will have to field the system with existing radar technology that has less range than a new generation of BMD interceptor missiles, the sources who have knowledge of the discussion told Reuters.

That could mean that while the interceptor has enough range to strike a missile lofted high into space, the targeting radar may not be able to detect the threat until it is much closer.

Japanese officials have witnessed a demonstration of Spy-6 technology, which boosts the range of BMD radars dozens of times, but efforts to secure the equipment from their ally have come to naught.

“There is no guarantee that Japan is going to get it,” said another of the sources. The U.S. Navy supports giving Japan the new radar, the source said, but may be thwarted by reluctance from the Missile Defence Agency, which is responsible for developing BMD technology.

Officials there are wary to release advanced technology, even to a close ally, before the United States has fielded the technology. The United States’ first Spy-6 equipped Aegis warship is not slated to begin operations before 2022, one of the sources said.

Tokyo will need permission to use Spy-6 well ahead of that roll out date to give the maker, Raytheon Co and Aegis system integrator Lockheed Martin Corp time to build and test the system.

I would support allowing Japan o purchase this radar.  Not only are they an important ally in the region but with this radar, they could become a first line of defense for the US from attacks by North Korea.  The threat is real and the situation will become dire soon of North Korea continues its threats to both Japan and the US.
