A defensive array could include a new radar system in southern Japan and possibly another in South East Asia, according to the Wall Street Journal.
The news came after an unnamed US official told Jane’s Defence Weekly that China’s People’s Liberation Army tested an intercontinental ballistic missile on July 24 which has the range to strike any city in the United States.
The DF-41 missile can carry ten separate nuclear warheads, each of which can be programmed to strike at a different target, the magazine reported.
The Pentagon is also concerned about China’s development of a new “carrier-killer” anti-ship missile that can strike at the US Pacific fleet.
