The territorial violation by China is the latest in a series of events amplifying tensions between Beijing and Japan.

A Chinese military surveillance plane breached Japanese airspace off the country’s southwestern coast on Monday, marking what Japan’s defense ministry described as the first known incursion by China’s military into its territorial airspace.

According to a ministry official, a Chinese reconnaissance aircraft briefly entered Japanese territory near Nagasaki Prefecture around 11:30 a.m. on Monday. In response, Japan’s Self-Defense Force put fighter jets on high alert and issued a warning to the Chinese aircraft.

While Chinese planes frequently appear in international airspace around Japan, this incident represents the first confirmed entry of a military aircraft into Japan’s territorial airspace.

    Doubt all you want, but you don’t have to meet a hypersonic missile where it is, only where it will be. They aren’t very maneuverable at their maximum velocities which means it’s possible to shoot them down with a slower intercept missile provided the battery is in a favorable location to make an intercept in time.

      Just fire the bullet to hit the other bullet, sure. Very easy and we do it successfully all the time.

      it’s possible to shoot them down with a slower intercept missile

      Theoretically.

        Tell me you don’t know what you’re talking about without telling me.

        You don’t need to hit the bullet with a bullet. You just hit it with a shotgun blast or grenade, either destroying it outright or blowing it off course enough that it loses its energy and becomes ineffective. We literally do this all the time on tanks and humvees. It’s called a hardkill APS. The Russians had one working in the 70s. Modern ones are capable of detecting incoming tank rounds moving between 700-1700m/s, identifying which will hit the vehicle, and blowing them out of the air once they reach 10-15 meters away. All in a span of nanoseconds. It’s standard equipment on Israel’s MBT, and Germany, the US, and the UK have all field tested various systems and are considering making hardkill systems standard for the next generation of tanks and IFVs. Multiple companies across multiple countries make them for upgrade kits. Germany already produces vehicles with standard hardkill APS for their export market.

        This isn’t crazy sci-fi technology. It’s just rocket science.

            That’s…literally how hardkill APS works. CIWS takes the same approach but uses a rotary cannon instead. The issue ain’t putting a missile in the path of the other missile. It’s in having enough time to do so. This is why the US concluded that the most effective way to intercept an ICBM is to destroy it before it finishes its acceleration stages. Ballistics is a known quantity.

            Still aren’t convincing that you know what the hell you’re talking about.

        You can watch this happen all the time in practice with slower missiles with the iron dome. The math is the same.

        This kind of pro-Russian cope was much more justifiable 2 and a half years ago. Now that reality has unveiled the decrepit, incompetent reality that lies beneath the propaganda, it’s just sad. I hope this cheerleading is just a halfhearted effort on your part (or that you’re doing it for a few rubles per post), otherwise this is pathetic.

          I mean, we’re saying this with a Boeing Starliner stranded at the ISS. But sure, America has a super-secret anti-hypersonic missile system that’s just like the Iron Dome (nobody ask how Hamas was piercing the Most Sophisticated Defense System in the world with a box full of scraps, btw) only 10x better.

          I hope this cheerleading is just a halfhearted

          This whole thread is nothing but cheerleading. You’re even fan-casting the existence of anti-missile systems the US admits it doesn’t have.

            You must have me confused with somebody else. I’m the one saying hypersonic missiles are pointless. The US toyed with them 50 years ago, and AD was obviously much less advanced than it is today. Not only that, but AFAIK the Sprint Missile is still the fastest of all time, so by your own standard where more speed makes for a better missile, you should be cheering for the USA.

                Speed comes at the expense of maneuverability. The laws of physics still apply, even in Russia (or on the internet).

                  It undeniably does until the DoD gets spooked and starts burying defense contractors in unspeakably large piles of money. Then you get the AGM-183A and where did the US choose to test it? Guam where China could would have a front row seat.

                  There’s so much ludicrous tech rolling out of the US MIC right now that it’s honestly getting hard to keep track of. Rapid Dragon missile deployment, hypersonic missiles, hypersonic planes, combined cycle rotating detonation jet propulsion, laser defense systems, next gen ICBMs, quantum radar, quantum lidar, underwater autonomous drones that can self power and remain hidden for months at a time…the list of verifiable stuff hurts my brain.

                    The 183 was cancelled, no? And yes, there are always lots of goofy sci-fi projects on the go. My favourite to date is MARAUDER, because it was cool and especially because of the acronym. It’s extremely unlikely that any of those will be produced at scale, though, let alone deployed anywhere. TBH I’m far more concerned about cyberwarfare and the negligent approach to cybersecurity in infrastructure than I am about high-tech weapons.

              hypersonic missiles are pointless

              An even bolder claim.

              the Sprint Missile is still the fastest of all time

              The theory behind the Sprint Missile was to deflect an ICBM with a nuclear blast. That’s definitely a potential solution to a hypersonic missile attack, but I’m sure you can think of a few reasons why it didn’t go into mass production.

                My point is that the concept itself is antiquated. The US restarted their hypersonic missile programs a few years ago due to media and public pressure caused by Russian and Chinese propaganda about their wunderwaffen. It’s one of those ideas like railguns that resurfaces every few decades and gets shelved again.

                Er, actually, I take it back… Please report to your superiors that hypersonic missiles are the future, and that decadent westoids are terrified of them. Prioritise these programs at all costs (other than keeping the Kuznetsov afloat, because that is also very important).

                  “Fast moving thing is hard to stop” goes straight back to antiquity, sure. But post-Cold War or mattered a lot less because we no longer had a first generation military adversary.

                  The US restarted their hypersonic missile programs a few years ago due to media and public pressure caused by Russian and Chinese propaganda

                  Yes, because the US media and the US MIC aren’t joined at the hip. GE Aerospace was strong armed by Hulu, which was strong armed by TEMU and Rosneft in turn.

                  Please report to your superiors that hypersonic missiles are the future

                  Americans will spend their last billion dollars on one more new aircraft carrier rather than go to therapy.

              a missile defense system has to be 100% effective to be real

              It can be 0% effective, so long as it turns a profit. The best anti-air system is the one people simply think is effective.

            I mean, we’re saying this with a Boeing Starliner stranded at the ISS.

            Meanwhile another US company, which is also a defense contractor, has revolutionized the space industry. It regularly launches satellites by the dozens and can rendezvous with the ISS anytime that NASA asks. The fact that one company, Boeing, is struggling with a product means absolutely nothing to the industry as a whole.

            But sure, America has a super-secret anti-hypersonic missile system that’s just like the Iron Dome

            It’s absolutely no secret. It’s a Patriot System and it’s quite capable of handling the laughable “Hypersonic Missiles”, i.e. repurposed non maneuvering ballistic trajectory junk from the 80s and 90s, that adversaries field today.

            Does the US have perfect gear that never fails? Absolutely not, some of our stuff is junk or near junk, but when it comes to this kind of thing the the US has no peer.

            You’re even fan-casting the existence of anti-missile systems the US admits it doesn’t have.

            We we have an entire Department dedicated to it along with platforms like SBX-1 and THAAD (among other things.)

            Again its not perfect but it definitely exists and it gets better every single year.
