The boomers are always on active alert, so would standby be a step down? I didn’t get what this would do. Everything is already ready to launch quickly and has been for decades.

But I can’t remotely set their allowable usage time and access list. Maybe dual booting would work though.

My issue is family control. I haven’t found a way to get Microsoft family type control yet on Linux, since my sibling uses my computer. The syncing time allowed across devices is the hard part.

I always said hypersonics are better at taking down carriers from my first comment here. But China didn’t have effective carriers. Hence why the US didn’t need them.

I said the US ones were extremely expensive, and you agreed. And that cost is the one that matters for the US.

Nuclear weapons aren’t useful in a conventional conflict by definition. So what is Zircon for if it’s not for MAD nuclear warfare and not for conventional warfare?

Did I ever say hypersonics were ineffective? I said they were expensive. And that stealth bombers are also effective at the ground attack role. Nothing you’ve sourced has contradicted that.

Aside from that, ballistic missiles can also get though most air defenses. MAD still works because you can’t be sure about reliability shooting down the missiles. Having even better more expensive ones doesn’t really change the math, which is why Zircon is so stupid.

Since China is now getting carriers, the US is testing hypersonics.

What system are you thinking? I’m sure the US can emulate it. Obviously systems can detect stealth aircraft if they’re right on top of them, it just makes the targeting effective radius small enough to be nearly useless. Detecting doesn’t mean much if it’s just a notification that there’s a stealth aircraft somewhere within 100mi.

The sources you gave earlier about detecting stealth are low frequency radars. And they said they’re good for detecting stealth fighters. Stealth bombers are more tuned for low frequency. (hence their goofy shape) Plus low frequency is very very difficult to get a direction to the target because of it’s scattering, it moreso just tells you there’s something there.

Kinzhal (the missile the articles are talking about) is the ballistic missile I was taking about, it’s not a hypersonic maneuvering missile.

I’m struggling with what’s the role of hypersonics if air defense penetration is already covered by the b2.

The US has tested stealth bombers against s300, because they got some. But they obviously don’t release the results publicly. They also have arrays that can emulate other capabilities like s400. So the US knows how effective stealth bombers are, and decided they were good enough at penetration not to need hypersonics. Now Congress and China getting carriers changed their mind.

When has a hypersonic missile (not the ballistic missiles strapped to planes Russia uses) penetrated heavily defended airspace? (There may be some, I know Russia definitely claims it, but I haven’t seen good proof yet)

So what missions does that mean they’re good at? Penetrating contested airspace that other attacks couldn’t?

No, what are stealth bombers good at?

Why do carpenters use hammers and screwdrivers?

Because they’re the best tools for the job

So what is the stealth bomber’s role that it is the best at?

So why is China building a stealth bomber?

when you have weapons that can engage from outside enemy’s air defense bubble.

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

The US has not had a peer conflict since the b2 entered service. (Good thing too!) But even so, Iraq had the heaviest air defenses at the time.

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.

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.

It’s f117, but with good planning they penetrated into bagdad, the most heavily defended city at that point, undetected.

Though it wasn’t quite as heavily defended in 2003, b2s and f117s did quite well against bagdad in enduring freedom.

2011 in Libya b2 was also used. Libya had hundreds of sam launchers, so I assume that was contested, though I can’t find as good of a breakdown as the other two.

Kosovo also had about a hundred sam missiles. Again I couldn’t find as good of a breakdown on where exactly the b2s flew relative to them.

So those are some times b2 has come into contact with air defense. Do you have any sources that they haven’t come into contact with air defense assets?

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.

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

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

I agree about the education system. But they’ve still got a ton of engineering talent. China is catching up, but they’re retreading tech the US has had for a while. But it is still very impressive how fast they are catching up.

What use case does a hypersonic fill that the US needs? Seems like you were saying ground air defense (like s400) penetration, but that’s what stealth bombers do. Or if stealth bombers don’t do that, what do they do?

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?

So why build the h20 if it doesn’t need to be stealth?

But why both? They offer the same penetration capability.

B52s were mas produced, only 21 b2s were built. B2s started in 97, after icbms. Which are you taking about?

So are stealth bombers effective? If so, you don’t need hypersonics against land targets. If not, China is wasting billions on the h20. You can’t have it both ways.

Why use them against asymmetric threats? Why in the world would you build a penetration bomber and then have it launch standoff munitions? The penetration role is mutually exclusive, no need to have two ways to do it.

US and Israel never fly them anywhere close to S400

Israel has b2s? That’s news to me! But it does make sense not to give to much signature info if there are other options available.

Why is China developing the h20 if hypersonics are always the best option?
