As I said earlier all the heat your engine is generating is being dumped via propulsion. You are heating the fuel with the things you’re trying to cool and then dumping the heat into the engine which is expelling the heat. All the internal heat from the aircraft starts from the engine anyways, since that’s what’s powering all the systems. Heating the fuel isn’t “adding” heat but recycling it back to the engine. You’re moving heat from the places you don’t want it to be to the places you’re okay with.

Yes I understand using fuel as a heat sink, but do not understand the original assertion that preheated fuel is actually beneficial in any way other than dumping heat.

I think it's possible that, due to the main bay being narrower than one on J-20, there is in fact no longitudinal separator wall like on J-20 or F-22, separating the space in two bays. But that, in fact, that there's a single space cavity for holding various weaponry. (once again, I am talking about main bay only, not the two smaller bays around it)

What is price tag after all those aggressive updates on NGAD? Kendall thought $300m is an unacceptable price. How about $1b for each new NGAD manner fighter? that’s not a joke since b21 already has a price tag of $800m

Is there a reason why B21 is that expensive? It has two F135-level engines. Using the popular theory in this forum, B21 won't have too much excessive power to drive the electronics and cooling thus sensor sets have to be limited. Then, it is not expected to be supersonic, thus lower requirements on the stealth paint. Yes B21 has a wider wingspan, that alone can't explain the cost

IF the B-21 generates less or as much power as something like a J-36, then it will be obsolete by 2037.

It also sorely needs IRST, and also not sure how the (forward) conformal arrays stack up against the cheek AESAs on the J-36.

It’s funny all this talk about how it’s not a 6th Gen fighter because of how big it is where it won’t be able to dogfight. I thought being 6th Gen was in part suppose to being able fly high altitudes where shooting them down won’t be easy especially for other fighters. It makes dogfighting moot then. That’s why it’s suppose to be about air dominance because they can’t shoot you down but it can shoot you down.

Why is there so much cockpit-glass behind the pilots? Based on the way it is depicted doesn't really conferr much backwards visibility.
