- Oh I know, supercruise. It's kind of new-ish. We got it on our Typhoon2 too. Rafale has it too.
We Brits have a history of making fuel efficient jet engines.....less smokey too.

(touch of early stealth there with that little characteristic. RAF
pilots always used to love exercising with US guys, you could see them coming miles off!

....which is pretty strange really as the UK gave the US
it's start with jet technology.....and kept passing along our good stuff into the 60's.
so its not the usual supersonic mode where you can only stay supersonic for a few minutes before you run out of fuel so that is a good
thing.
- well that's true-ish. 'Minutes' is a tad severe, I'd say.
It
is - by far - preferable from a fuel consumption point of view but it isn't the answer to everything. Kinetic heating will still be a major
problem, sound too. It's a transit thing, rapid reaction/deployment, you can choose to use by and large as I said.
You were more right about this originally. Go supersonic and you lose a lot of your stealth ability.
Also there is a reason the US planes cost more because they can still be good after 30+ years.
- Yeah but that's the game all play these days. No-one is going to put up with a short-lived multi-million cost system.
Seriously, the US approach to design is (or, to be more fair and accurate, definitely has been) as I described. UK design staff working in the USA are
always astounded at the sheer weight of man-power and money throw at development in the US. It's your culture.
