If you think the people of Russia/China/NK are winning, then I'd hate to see what losing looks like.

The friendship with Russia/China is more convenient for Japan than that of an old and decadent regime disguised as "democracy and good will"...

You have to be on the side of the winners..

LOL

Forewarned is forearmed.

It sounds like a very good idea.

China Russia,NK already have the capability to launch a decapitation strike against Tokyo as little as 5 minutes from any launch site

Really? So you're telling us that everyone here at JT who constantly claim that Japan has no need to better arm itself because none of its neighbors pose any threat, is in fact, wrong wrong wrong. I'm shocked.

So? The US has multiple independent, highly survivable platforms to turn China, Russia, and North Korea to dust.

There's no such thing as a temporary extinction of the human species. Once the first nuke flies, there's no reason to not launch ALL of them ALL at once.

China's arrogance is no defense against 5000 ICBMs.

China and Russia are well ahead with hypersonic technology..

The US has been testing hypersonic missiles since the 1970s. ASALM exceeded Mach 5 in tests way back in the early 1970s. This was an air launched missile. The problem then was guidance. It was moving too fast for the processors and sensors of that era so it had a low Phit, or Probability of Hit. The US had maneuverable ballistic missiles back then too, Pershing II. It had control surfaces and a terrain matching radar for finding its target and maneuvering to hit it precisely, at the hypersonic speeds of a ballistic missile on re-entry. The US was doing this decades ago.

The Holy Grail for the US isn't these boost glide vehicles the Chinese are trying to make work or stuff like Kinzhal which is nothing more than a battlefield ballistic missile hung from a jet, but air breathing hypersonic weapons, of which one is coming on line very soon. The real goal is to have a compound engine that is a turbojet for a ground take off through about Mach 4 after which there is a transition to scramjet for sustained hypersonic flight. There are prototype air vehicles being built to fly later this year and their engines have been in testing for the past two years.

I think the war in Ukraine has shown that you don't need to go hypersonic to give dictators a very bad day.

Not a lot of understanding of ordnance here but that is to be expected. The US has already demonstrated the ability to intercept and destroy hypersonic missiles. Patriot has shot down Kinzhals and Iskanders on multiple occasions. New higher performance versions of Patriot are being produced now for the US, Poland and Ukraine called PAC-3 MSE. A PAC 4 using a Raytheon built ballistic missile kill vehicle currently in service with the Israelis is also coming. Look at Stunner and you get the idea. That is US tech. And it can be deployed from aircraft in addition to ground launch.

So what should Japan do? Move to another country, or surrender? Or should Japan develop the same capability as soon as possible?

@Yarrl, you often mention Japan is close to imminent destruction from China, Russia or NK, but you say nothing else. What is your idea of a solution? Just curious.

The implied suggestion being Japan would be better off siding with 2 autocratic leaders who will not give up power, who wish to expand their empires at the expense of other smaller nations, and just shut up, do as it is told or risk some form of punishment? This is better for Japan and its people over its current friendly relations with Europe, North America and the Indo Pacific how?

Japan is treated as a friend and partner with many nations, and is approaching allied status with a number of its friends. So Japan is better off throwing all those relationships away to join the autocrats club of China, Russia and NK? Who will become Japans autocratic leader for life? Any suggestions?

I dont buy the premise of switching sides. I get it would be much better for China and Russia if Japan did so but joining the small anti west club has no real world advantages for Japan.

In many ways they are over rated. They are hideously expensive to manufacture so their unit cost is very high. That means you can't buy as many of them as you can less costly subsonic cruise missiles. Yes they are more difficult to track and engage, but by the same token that high speed gives the missile a lot less time to find a target and maneuver to hit it. Against moving targets like ships or missiles systems that are on the move (you do want to hit your enemies mobile nuclear missiles for example) they are probably inferior to subsonic systems that have more time to conduct a search, classify what it sees, select a target and maneuver to hit it. The subsonic missiles also fly a lot lower and can be even more challenging to detect than a high flying hypersonic screamer. So a mixture of systems is what military's that can afford it will buy. Throwing a mix of different missiles at a target often improves the chances of getting past the defenders and hitting the target.

@Yrral Let me google that!

China Russia,NK already have the capability to launch a decapitation strike against Tokyo as little as 5 minutes from any launch site

@Yrral Don't know where you get your information from your logic seems to amaze me. There is also a policy that rules of engagement can be over ruled in critical emergency need based on the situation. I GOOGLED THAT!!

USN,the US do not have a policy to use nukes to protect Japan,beside 2030 do not make up for an immediate 5 minutes decapitation strike in Tokyo,that they face now

Interesting old news but I know those companies very well. Lose lips sink ships!! Seeing is believing, very different from being well informed and involved!!

Japan and the United States on Wednesday signed an arrangement to jointly develop a new type of missile defense system as the allies seek to defend against the growing threat of hypersonic weapons, which are possessed by China and Russia and being tested by North Korea. The cost includes making components for the two companies, Raytheon Technologies and Northrop Grumman, that are developing the weapon in a competition led by the U.S. Missile Defense Agency. One will be chosen for the project.

That's surely only a very first step of many necessary ones. Next requirements are of course considering also other technological developments like drones etc and in general the related outnumbering problems. The new capability to intercept a hypersonic missile might be looking nice, but what to do if there come a lot and each carrying several real or dummy warheads? The same for drones, when jamming or intercepting one is already quite challenging, but how to handle one or many big and connected or AI self-coordinated swarms of drones? Chances for reaching a successful defense with a sufficient success percentage of at least a significantly over 90% interception rate are still extremely low in both scenarios, the multi hypersonic or drone swarm one, if there even are any chances in practice, not only in a one time training environment under ideal optimistic parameters and conditions.

The MDA has estimated the cost to develop the hypersonic missile interceptor will exceed $3 billion, including Japan's share of $1 billion.

As normal, development costs and finial price will be massively higher.

Will it stay under $10 billion ?

Has a future global conflict, possibly a third world war, however near or far become inevitable?

What would that conflict, the acceptable losses look like in the event of a battlefield tactical nuclear exchange?

Could such a exchange be contained?

The reprehensible threat to humanities existential risk?

It is wise to fully consider such a future.

0 ( +1 / -1 )

No, no, no. Japan should not give any assistance to a country that supports genocide. America will give weapons developed under this trade deal to Israel. America already has too much weaponry and gives too much to Israel

We should never repeat the mistake of defeat.

China and Russia have never been the sole winners.

Without American support, even China and Russia cannot necessarily become winners. History proves it.

It is natural for Japan to arm itself in order to confront enemy countries such as China, Russia, North Korea, and South Korea. I would like to see further additions to the defense budget, with consideration given to the development of nuclear weapons.

Solutions is Japanese leaders always running their mouth ,while hiding behind US perceived power, maybe they should just zip it

Agent , Japanese was guinea pig of the use of nuke, something they should not want to have in their possession,beside

Ryan,USN,the US do not have a policy to use nukes to protect Japan,beside 2030 do not make up for an immediate 5 minutes decapitation strike in Tokyo,that they face now

It was the next-generation fighter jets that Japan signed with the U.K. and Italy to jointly develop. This time, it is the hypersonic missiles that Japan signed with the U.S. to co-develop.

Hey, there is something unforgivable going on in the Japan-U.S. relations to make Japan an abominable military country once again. Have they forgotten the national pledge inscribed on the Hiroshima epitaph that partly says, "We will never repeat the same mistake"?

Japanese general public seem to have no even recognition that own country expands relation with the war by ruling class.

Very late now, as Russia and China has been moving ahead quickly. America is s very bully country, they treat their easy allies like ATM whenever and whatever it cost !

Good luck with that..

China and Russia are well ahead with hypersonic technology..

Japan is on the wrong side of history..
