Having it shot down is not a consequence. Diplomatic or economic retribution of some kind would be a consequence.

Why not hydrogen instead of helium? It's much cheaper and lighter.

https://en.m.wikipedia.org/wiki/Hindenburg_disaster In all seriousness, I have no idea.

This is an unmanned device so it doesn't have the same safety concern. Also at the cruising altitude there is so little oxygen it's probably as safe as helium at that altitude.

Why would you need to police population in case of war for returning Taiwan? It will be very popular war and you definitely won't need to lock people down.

Look at Russia as an example. The war has been longer and less popular than expected and economic sanctions have hurt the working class the most. China imports 66%-75% of its oil. That would drop dramatically in a hot war, as oil imports via the South China Sea would likely be blocked. This would require any imports to sail around Australia, which would likely be stopped by the US. Russia would happily sell China oil…

If anything, war is much more popular in Russia than expected. There are no widespread protests, draft went ok, etc. Putin is still popular.

I do not think oil is such a big problem. China import is 10mln barrels while Russia exports is 5mln barrels, Kazakhstan is 1.2mln barrels. I am sure they can transport Iranian oil if needed. What will also happen is that Russia will buy oil on international market to resell to China. There is no infrastructure now to transport that much oil but it can be built surprisingly fast. Germany just demonstrated that it's possible to built LNG terminal in six months. If you ignore property rights and all enviromental regulation and enlist military you can built trans-asia pipeline in a few months. China can also import oil thru Vietnam.

Sorry, maybe it wasn't obvious enough the first part of my comment was intended as a joke?

Also maybe gives China cover/justification to start shooting down these low satellites.

That’s an escalator that China can’t afford to ride. The US would deorbit everything China ever put into space if they started shooting at satellites. Those satellites are part of the strategic triad and would be a direct threat to the US nuclear umbrella. The AEGIS systems off the Chinese coast would take care of any attempts to add satellites back into space.

Low-Earth orbit satellites are not currently part of triad (but may be part of a future nuclear defense shield / interceptor system). They are also much easier to shoot down.

See Space Development Agency https://en.m.wikipedia.org/wiki/Space_Development_Agency

That's what China has been most upset about at United Nations.

We need a cheaper way to down these spy balloons. The sidewinder missile + F-22 flight time costs are an order of magnitude greater than the total cost of launching one balloon. Send over the High Energy Laser with Integrated Optical-dazzler (HELIOS) to protect the west coast.

The big balloon from earlier this month was more like a satellite hanging from a balloon. Not sure it was that cheap. The problem is what can you fly that has a cannon and can reach those altitudes. Apparently only the F22 and F15 could, and that was their very limit.

Earlier this month? It was last Saturday!

How much does a weather baloon cost? ...compared to a F22 flight, a missle + all the logistics? If it's cheap enough, there will probably be youtubers and tiktokers buying them en-masse just "for the lulz".

> How much does a weather baloon cost? ...compared to a F22 flight, a missle + all the logistics? If this is an actual spy object you also need to factor in the cost of the surveillance. How much money does the military lose due to the sensitive information being lost. Or how much does the military need to spend to regain strategic advantage? That probably costs more than a F22 flight and a missile. Obviously this de…

I don't think it would be a stretch to say that we're in a cold war with China. Many modern battlefields aren't on the ground and fought with bullets. They are economic, political, and proxies. In cold wars you often have technological and economic races too (see cold war with Russia). Militaries believe that if you don't want a hot war to break out you wave the biggest {st,d}ick. It would be naive to believe that mi…

I’d hesitate to call this psychological warfare, but it now seems like the American people are paranoid about spy balloons and having their airspace violated. America is the one who brazenly flies and spies over other countries, that doesn’t happen to us.

So now our leaders are trigger happy about shooting down any potential new balloons in order to try and save face while looking tough. Meanwhile, I’m sure plenty of Chinese officials are feeling pretty smug at the reaction they were able to cause and pride that they can present themselves as a capable challenger to American hegemony.

This was supposedly done during the US bombing of yugoslavia... open microwaves transmit pulsed radiation, automatic systems think it's a radar and bomb the site.

Can confirm this and that it happen in both Bosnia and the Serbia campaigns. I had family members who were involved [0]. The deception methods that were applied were truly remarkable, they used decoy tanks and sent people out to imprint fake tank tracks into fields. They also understood IR and would shield real troops while leaving coal to burn in empty pillboxes and bunkers There was also the shoot down of the F-117…

I heard the downing of the f-117 was due in large part to them flying the same patterns at the same time every night. Was this true? Or was there more involved in the AA hit?

How many Olympic-sized swimming pools is that?

For better picture, Olympic-sized swimming pool is 50 meters long.

So about 11 carometers long (which is roughly 5 busometers).
