The two nations have been doing research on missile defenses for some time, and are now crafting an agreement to focus that research at sea and do some testing of a promising system. The development comes as the two nations are expressing fears that North Korea might fire another rocket across Japan. Jim Randle reports from Tokyo. TEXT: One idea is to upgrade the air defense system on ships to handle the far more difficult task of shooting down fast moving missile warheads. The current U-S Navy Aegis system uses powerful radars to sense targets, advanced computers to keep track of them and a fast moving missile to shoot them down. Defense experts say shooting down a missile warhead is essentially hitting a bullet with another bullet. To do that, every element of the current system will have to be made more powerful and faster. Japan already has some advanced ships equipped with the Aegis air defense system that could be the starting point for a missile defense system. A senior defense official says Japan's island geography might also make a shipboard system a logical choice for Tokyo. U-S officials say the two nations have been doing some studies of missile defenses and are trying to pick the most promising path for research. They say a formal agreement is under discussion and that would commit more money to the project and result in a limited amount of testing over the next two years. The deal covers legal and technical details, including limits on transferring the technology to other nations, and the financial responsibilities of each side. Officials say the agreement is nearly finished, but will not be signed during U-S Defense Secretary William Cohen's current visit to Japan. The talks come as North Korea may be getting ready for another ballistic missile test. Pyongyang fired a rocket last year that roared across Japan and far out into the Pacific. North Korea said it was launching a satellite designed to play revolutionary hymns into the cosmos. But no satellite was ever detected by space-tracking radars, and many Western defense experts said it was actually a weapons test. U-S intelligence officials said a few weeks ago that work at a North Korean launch pad meant Pyongyang could launch a new rocket in a matter of weeks or months.(Signed) Neb/jr/plm 27-Jul-1999 00:02 AM LOC (27-Jul-1999 0402 UTC) NNNN Source: Voice of America .
