The U.S. military’s Forward-Based X-Band radar is scheduled to begin operating from the Japan Air Self-Defense Force’s Shariki Base in northern Japan on Wednesday, according to an announcement Thursday from Japan’s Ministry of Land Infrastructure and Transportation.

The surveillance, detection and early warning system is designed to find and track any missile launched in the region against Japan or the United States.

Officials had said the radar was scheduled for a June move to Shariki Base before media reports surfaced that North Korea might test-fire a long-range ballistic missile.

The mobile radar — which cannot intercept a missile — was stored at Misawa Air Base, Japan, after arriving in pieces earlier this month from the States. A local news station reported that it moved on Friday.

The Japanese government reported in a news release Thursday that a no-fly zone would be established “indefinitely” around the radar when it begins operating Wednesday “to prevent negative effects of electric waves emitted from the radar on aircraft radars and such.”

The no-fly zone would cover an approximate 3.8-mile radius around the site and the same distance above it. Japanese government and U.S. military officials have said that the system’s electromagnetic waves would not affect the environment, human health, televisions, radios or cellular phones.

In showing parts of the device to local media and Japanese government officials for the first time in early June at Misawa, Col. Stephen Town, Army and Air Missile Defense Division director, said the radar sends a strong message: “We know what you are doing; we can see what you launch.”
