Exclusive: U.S., Japanese firms collaborating on new missile defense radars - sources
By Tim Kelly and Nobuhiro Kubo | TOKYO
Raytheon Co and Lockheed Martin Corp are working with Japanese partners on rival projects to develop new radars that will enhance Japan's shield against any North Korean missile strike, government and defense industry sources in Tokyo told Reuters.
As nuclear-armed Pyongyang builds ever more advanced missiles with the ability to strike anywhere in Japan, Tokyo is likely to fund a ground version of the ship-based Aegis defense system deployed on warships in the Sea of Japan, other sources had said earlier.
