Check last post in thread. By my calculation, if we have a constant 1MW electric generator, it would need 400L of jet fuel per hour! F-35 only carries 10500L of jet fuel. So if you want an aircraft that can operate 10 hours in the air (4000L of jet fuel), you need to carry huge amount of internal fuel.

Obviously, if you are aircraft is just cruising to destination, you don't need to use that much electric generation. This is just to put things in perspective.

I'm all on board with electric air cruiser but 1MW is bit much, peak consumption with the help of battery maybe. What do you think is the most energy demanding component? Radar, EW, comm, computation...etc

Intercepting 7th gen and even 6th gen plane is pretty much impossible. This means countries that have those planes no longer need do develop actual ICBM to have credible nuclear deterrence, as long as they have a deliverable nuclear payload, even in the form of a bomb.

I wonder if there will eventually be an equivalent of 6th gen and above aircraft anti-proliferation treaty.
In short I don't think anything 6th gen and above will be for export.

I’d tap the brakes a little on 1 MW sustained power. Might still be more aspirational for now.

I agree, I think speculation and estimates specific numbers for things like that are definitely better left not said too confidently, mostly due to the sheer amount of unknowns that feed into a final number.

I made it big in the China watching circle. If anyone from DC is reading this PM me so I can instruct you on where to deposit the DOGE coins.

You've been locked on, quick deploy countermeasures!

In retrospect even though we had a good feel Guancha team knew a lot beyond what they're allowed to say on air the amount of info Yankee was privy to was still surprising. He said in the previous Chahuahui that he knew the layout of J-36 two years ago and when questioned by Ayi at Zhuhai this year on where the 3rd intake was and if it was on the back he gave him a plausible deniable nod. He really is worth the "and now even Yankee" comment.

With CJDBY gone those three have become one of the best sources, it helps they're witty too. They're like the Top Gear of PLA watching.

I am not sure how this works either with 1 MW generation. Typically I think anything that relies on high intensity RF (radar and EW) is the most energy intensive.

But do you really need THAT much RF power?

The flight computer itself should take little energy and comms should be moderate. IDK enough about computing to judge but I don't think the power required to train an AI model is the same as the power required to simply use a pretrained model where you just load model weights. Even if you have like a few hundred pre-trained models for different scenarios, that's just storing numbers, as long as you don't need to figure out those numbers in the air.
