Looks like people in Mexico weren’t fooled by US propaganda.

I’ve explained to you repeatedly with multiple examples of the roles that hypersonic missiles are better at. You just kept ignoring that and repeating the same line over and over like a broken record. Read what I wrote and address that.

yogthos OP , 1 month ago to technology in Human culture is changing too fast for evolution to catch up – here’s how it may affect you

Indeed, and this explains a lot of the problems we’re having on the global scale as well. Our brains are optimized for a relatively static world where we have short term concerns like not getting eaten, and making sure we can feed ourselves. We didn’t need capacity to plan decades into the future throughout most of our existence. Here and now was always more important, and our psychology prioritizes immediate wellbeing. It’s hard for us to make sacrifices that reduce our current standard of living for the benefit of our hypothetical selves sometime down the road.

This is precisely what gets us into trouble when it comes to dealing with large scale problems like the climate crisis. Most people understand on an intellectual level that this will be harmful, and that we need to be addressing this problem. However, the scale of the problem is so huge that it’s difficult for us to understand it on an emotional level in a way that would spur us into action. It would mean having to make serious changes to how our society is organized, our consumption habits, and so on. So, we just keep doing what we’re doing while the problem keeps getting worse.

So why is China building a stealth bomber?

Why do carpenters use hammers and screwdrivers?

Exactly. You can fix that by increasing the range of the weapons, or by decreasing the range of the air defense bubble with stealth.

Again, nowhere have I argued that stealth tech is useless. What I keep telling you is that these are two different types of weapons that serve different roles, and can complement each other. I really can’t understand why this is so hard for you to process.

Again, Iraq air defences were incredibly dated technology. They’re not representative of modern capabilities.

Obviously stealth just decreases the detection range, but it can decrease it so far that you can weave between the mile or so of air defense detection and still drop bombs.

Given that, as you admit, this hasn’t actually been tested in practice, nobody knows how well this works. The links I provided above make it pretty clear that stealth aircraft can in fact be detected, and this is just public unclassified stuff. Furthermore, as I’ve already stated earlier, the missiles and bombs the aircraft uses can themselves be intercepted.

Yeah hypersonics do do that, but none of that needs stealth! They’re standoff range munitions, you’re outside of the enemy air defense bubble when you fire them, because noone has an air defense bubble larger than their range.

Right, that’s my whole point. You don’t actually need stealth when you have weapons that can engage from outside enemy’s air defense bubble. And having weapons that can fly really fast makes them far more effective because they can engage very quickly despite long ranges. Response time is everything. Incidentally, the plasma bubble that’s created by a hypersonic weapon as it superheats air in flight also acts as radiowave absorbing sheath making the weapon stealth. This further reduces already minuscule response window.

Again, Iraq and Libya were not a technologically advanced nation by any stretch of imagination. The air defences you’ve listed are ancient, and have little to do with what modern systems are capable of.

The stealth tech reduces the signature, but it doesn’t make it go away entirely, and it’s vulnerable to different types of radars working in combination. Furthermore, nowadays there is a lot of other telemetry that can be integrated such as heat, and sound waves it produces, and all this data can be analyzed by a computer in real time to pinpoint it.

Hypersonics (at least the maneuverable boost glide versions China has) need to get into the upper atmosphere before coming back down gaining momentum. That means they effectively have a minimum range to get up to speed. That minimum range is already larger than any heavily contested air defense zone, making stealth on the carrier aircraft redundant.

China has a range of hypersonics the same way Russia does because they do tech transfer with each other. Russia has been launching hypersonics from ground, air, and sea, and these have been an absolute nightmare for NATO defences in Ukraine.

One other huge advantage of hypersonics is that they give very little reaction time to the enemy. Launching a bomber and waiting for it to get to the target literally takes hours. A hypersonic missile can hit within 5 minutes. This means that an integrated system can use a satellite to detect a target, such as a B2 landing on the airfield, and notify appropriate launch system to eliminate it, and a hypersonic missile will come down on it within 5 minutes from over a thousand km range.

Check the operational history section on the b2 page, it’s got a bunch of stuff since 2000.

When again has B2 come in contact with actual air defence?

But again, why would Russia and China be designing/building stealth bombers if they don’t actually work?

Because they both serve a different purpose. Stealth bombers do have a lower profile than regular jets, so theoretically they can get closer to the target. However, the bombs that B2 drops can also be intercepted even if B2 itself isn’t. So, launching hypersonics from a stealth fighter is still obviously advantageous.

China is catching up

Seems to me like China has plenty of tech, like hypersonic missiles, that US doesn’t have. Here are a few more examples for you

even a US propaganda outlet is admitting that China is surpassing the US in military tech www.voanews.com/a/…/7124026.html

yogthos OP , 1 month ago to technology in Pioneering ‘shark skin’ tech could propel China ahead of US in jet engine race

Nobody has actually seen a stealth bomber do that in practice. In fact, this is what happened last time US tried using one

en.wikipedia.org/wiki/1999_F-117A_shootdown

Anyway, why do you think is the reason the US doesn’t have hypersonics, and why is that reason is the same as why they won’t put shark skin in their engines?

Because US is technologically behind due to having a piss poor education system and not being able to poach talent from around the world the way it used to. US is a decaying empire that’s spiralling the drain right now.

yogthos OP , 1 month ago to technology in Pioneering ‘shark skin’ tech could propel China ahead of US in jet engine race

It’s like asking why have a hammer and a screwdriver. Absolutely incredible that you can’t understand that different tools have different uses. I mean you’ve literally just disproved your whole thesis here. If bombers served the same purpose as hypersonics, then China would just build stealth bombers. Instead, they’re producing both. The reality is that you’re just coping with the fact that US is falling behind technologically.

ok there expert

yogthos OP , 1 month ago to technology in Pioneering ‘shark skin’ tech could propel China ahead of US in jet engine race

They clearly don’t. Hypersonics can hit targets from a huge range in minutes, and they’re nearly impossible to stop. This has been proven in actual use. They’re also much easier to hide, cheaper to maintain and to produce. In fact, hypesonic weapons is precisely what you’d use to take out bombers on an airfield. These are just a few obvious things off top of my head. There’s been plenty written on the subject by many experts. Maybe go read up on that instead of trolling here?
