News Chinese "weather" balloon shoot-down over US

[boneh3ad]

Interesting, "Perhaps you recognise me, it's your favourite president" said "It never happened with us under the Trump administration and if it did, we would have shot it down immediately."

However, "A senior defence official confirmed that Chinese surveillance balloons passed over the US "at least three times during the prior administration" but were not shot down or revealed to the public." - https://www.stuff.co.nz/world/us-ca...sed-us-skies-under-donald-trump-pentagon-says

To be fair, it appears (according to NORAD) that those balloon incursions were only identified after the fact:

needed special permission to do so

? Permission from whom?

 

[boneh3ad]

? Permission from whom?

That's a pertinent question and I don't know the answer. Normally the military (or CIA or FBI, for that matter) isn't allowed to collect intelligence on US soil. So I'm not sure who makes that call. I would guess probably the FISA Court would have to issue an appropriate warrant.

Some new details from USNORTHCOM via Aviation Week:


Summary:

• The US military likes to discuss the size of things in terms of the size of other things, apparently. How many bananas wide was the payload?

CNN says it's the size of three coach busses, so I'm not sure who to believe.

We need to finally agree on SI bananas as the unit of measure. Please folks, let's stop being so obstructionist...

 

[boneh3ad]

CNN says it's the size of three coach busses, so I'm not sure who to believe.

The length of a plane in the Embraer E-Jet family ranges from about 2 to 3 coach bus lengths, so it seems consistent. But I don't know if that is metric coach buses or US customary coach buses (also known as greyhounds).

That's what I heard first. Later I heard that was the size of the payload [3 busses]

Even worse of a situation, in my view.

Sure, but it does offer one possible explanation why the government may want to let it overfly the country while gathering a ton of intelligence: so we can track them better in the future.

15 football fields by 15 football fields?
We used to call this "a square mile".

Which is a lot better to be looking for parts and pieces than seven square files, but is still a big, big area. Underwater does not make it better,

*****The Chinese have >500 nuclear warheads, many on ICBMs*******

What is Soooo Terrifying about a large balloon? Am I missing a fundamental point here? Is there a balloon gap? Is this some wierd theatre?

 

[berkeman]

Is there a balloon gap?

I think the gap was because we did not have any way to bring down the balloon from 60k' in a controlled way so it could be grounded right after it was detected. All we had was fighter jets with missiles, so had to wait until over water. But as @boneh3ad says, part of that wait may have been useful as well.

There is the issue that the US has not been detecting them. It is not clear if this has been addressed or if the US was just lucky this time. This has counterforce implications.

I just saw this in the Lame Jokes thread, posted by @nsaspook and couldn't resist cross-posting it here.

If it is such a threat just shoot it down. Big airplanes crash at high lateral speed and usually do little human damage unless over a city.
In the big scheme of things this just seems nuts. So we need an anti-balloon system? Can I get a piece of that development money?

 

[berkeman]

Can I get a piece of that development money?

Now would seem to be a good time to apply!

From https://business.defense.gov/Work-with-us/Guide-to-working-with-DoD/

It typically takes at least 18 months of planning before a government contractor wins their first contract. Plan to invest significant time and resources becoming procurement ready, identifying potential opportunities, marketing to potential clients, developing proposals, implementing your first DoD contract and complying with DoD rules.

Who is terrified? The Chinese sent a spy device and violated our airspace.

I see some media claiming people are terrified, but I have seen no such thing in fact. People made a bit of a thing to watch for it for fun. And we want to know what the Chinese hoped to accomplish.

The only useful spying it could do that a satellite couldn't that's I've heard about, is to monitor low-power transmissions used for our nuclear weapons systems - too weak for a satellite to detect. That is a bit bothersome. In a worst case it could be a prelude to nuclear war. But they have to know we would jam any potential signals... unless they hoped to sneak it in.

 

[boneh3ad]

A good discussion of why balloons are pertinent: https://www.c4isrnet.com/battlefiel...ns-could-complement-space-based-intelligence/

The issue of nukes is irrelevant. It's a totally different mission and threat.

 

[Ivan Seeking]

The issue of nukes is irrelevant.

Not according to Leon Panetta - former secretary of Defense

 

[Ivan Seeking]

In fact your own source says what I just said

Tom Karako, director of the Missile Defense Project at the Center for Strategic and International Studies think tank, said one benefit of these balloons is their ability to hover closer to the ground than satellites, and they may be able to intercept communication or electronic signals that orbiting systems can’t.

My fear is, that it is part of the preparation to deal with the Taiwan issue. It could have served multiple goals in this respect:

• reaction time
• severeness of reactions
• spying facilities in the northwest
• testing jet streams relevant for potential fallouts
• and what else might be relevant for military personal

I haven't seen whatever he said. I suppose you could put a nuke on a balloon and it would be harder to detect but easier to shoot down than an ICBM.

Also, if a country decided to openly nuclearize a balloon, it immediately means they can't use balloons for other more useful purposes because everyone would assume it's a nuclear attack and retaliate. It's the same reason we don't have conventional ICBMs and why the US isn't planning to develop nuclear hypersonic weapons.

So to me, saying "why should I worry about balloons when they have nukes" is akin to saying "why should I be concerned about smoking cigarettes when I could die in a plane crash tomorrow." Unknowingly giving up intel is how you lose future wars.

 

[Ivan Seeking]

I haven't seen whatever he said. I suppose you could put a nuke on a balloon and it would be harder to detect but easier to shoot down than an ICBM.

What I said: We use low-power communications to coordinate our nuclear weapons system. We use low power specifically so satellites can't detect those communications. A balloon is at much lower altitude so it could detect those signals.

Those are likely the most classified communications to be found. And it followed a track that brought it close to several critical nuclear sites, like Malmstrom AFB.

Hopefully the payload will be intact enough to determine the motive.

Okay, okay, we got this folks. I've been doing a little research, and we can put together a PF Team that can be available at a moment's notice if this happens again.

We can have several of these aircraft made available to us to get us to 51k', and our deer rifles can do the rest. I'm taking sign-ups at the following website; only apply if you have experience shooting your deer rifle while hanging out of a Leer jet at altitude. Wolverines! www.spacecowpokes.com

I think we need someone to jump wearing a jet pack, to get the last bit of altitude.

We can send Brady. He is currently available and an expert in deflation.

I'd ask for a source, but if you had one you probably couldn't share it. But honestly, it would be stupid to use lower power over-the-air comms to communicate short distances over the terrestrial US. Coax or fiber would work just as well, and be immune to over-the-air sniffing recon.

No, I heard it in an interview. If you need to make a fuss I'll try to find a source. I said I heard it from Leon Panetta. I didn't mean personally.
