Japan, U.S., S Korea to share N Korean missile info

They cannot accurately track.

Not if they function as well as the Russian hypersonics launched at Ukraine.

If NK can manufacture hypersonic weapons over Mack 7, then it will be time to remove sanctions and be nice to them. I feel sorry for the people of Okinawa, Guam, Hawaii because of geopolitical games with high stakes.

If NK can manufacture hypersonic weapons over Mack 7, then it will be time to remove sanctions and be nice to them.

Is NK still a little NPT violator? Than it is time to give them nothing.

If NK can manufacture hypersonic weapons over Mack 7,

An opinion from someone who doesn't know the difference between Mach and Mack carries little credibility.

Not if they hypersonic !

North Korea has been routinely having problems with much simpler technology.

Does this mean J-Alerts will be timely and accurate!

Not if they hypersonic !

They cannot accurately track.

Are you sure about that? Patriot has shown it is quite capable of tracking and shooting down Mach 10 Kinzhal missiles and similarly hypersonic Iskander surface to surface ballistic missiles. Not just once in a test either but dozens of times in actual combat.

The US Navy shot down an old US satellite orbiting in space at some 17,000 mph using an Arleigh Burke class DDG, it's AN/SPY-1D radars and an SM-3 Block 1 missile.

The JMSDF has shot down an ICBM target off Hawaii it tracked with its AN/SPY-1 radars and the new SM-3 Block 2 missile Japan and the US are co-developing.

North Korea has been routinely having problems with much simpler technology.

Most of DPRK's ballistic missiles are "hypersonic" inasmuch as they exceed Mach 5 during re-entry. Mach 5 is the threshold for calling something hypersonic. They have demonstrated at least once a maneuvering warhead. That is not a hypersonic glide vehicle but something closer to the old Pershing II IRBM that had a radar that scanned the target area, comparing the scene below to a digital map of the target loaded in its memory and control surfaces that allowed some degree of maneuvering to improve accuracy so the warhead could be smaller and lighter while still giving the same effects as a larger but less accurate weapon. So DPRK has shown they can do that to some degree but they haven't yet demonstrated a hypersonic glide vehicle such as the US, Russia and China possess.
