You are all over the place here.I dont think aircraft can be equated with EV's in this respect. Also what i mean with cooling demand is What kind of cooling capacity you need to cool the aircraft not the amount of power required by the cooling. So you cant really put it in power consumption there.
Let's say you want a DEW laser say 250 KW even with 50% efficiency you have at least 125 KW of waste heat, this needs to go somewhere, especially not to cause increase in IR Signature of the airframe.
Radar, say your MW level power plant can allow 100 KW of prime power to Radar, typical prime to radiated power efficiency is about 25% or maybe 35%. Only 35 KW of average power is radiated, leaving you with 65 KW of waste heat
ECM's you need a wide bandwidth amplifier for this, and for solid state, this tend to lower PAE (Power Added Efficiency) so no more 25-35%, it can even be as low as 20 or even 10% if you want coverage to say X-band to L-band. You let another 100 KW for the jammer thus about 10-20 KW of power with 90-80 KW of waste heat.
That makes some 370 KW of cooling demand here. For stealth it will most likely be going to fuel as heat buffer.
My point is that you are not factoring in the advancement made by China in cooling technology of electrical platforms. There is a lot of R&D ensuring that electric motor, batteries, charging, RF base stations, AI data centers don’t overheat. I am not going to debate you further on what the size needs to be. If you believe it’s that large, it’s not worth my effort to argue this with you.
as for your other point, my comment about 1MW power consumption is about what the aircraft needs. The actual subsystems that use them may very well be just 50% efficient. That’s not relevant to what I’m saying since I never said the laser or radar are fully utilizing the energy going into platform.
