US Navy 6th Gen Fighter - F/A-XX

[Not James Stockdale]

To those discussing the obvious reasons why F/A-XX might benefit from adaptive three stream engines or believe that two F135s is a no brainer… See this post

Keep an open mind.

I thought it was a version of the f414?

Those are nowhere near powerful enough for a plane that will be at least the size of a Tomcat.

That depends on TWR you want; GCAP consorsium doesn't appear to be bothered.
And iirc there are indications FA-XX won't be especially super size.

That depends on TWR you want;

TWR > 1 at 50% fuel with full air-to-air loadout. Basic fighter standard.

40klbs empty weight, ~8klbs of ordnance, and ~14klbs of fuel means a minimum of 62,000lbs of thrust is required. That's 31-35k per engine.

F-22 standard would be TWR >1 at takeoff with full fuel and air-to-air loadout. minimum 40k per engine.

GCAP consorsium doesn't appear to be bothered.

GCAP consortium isn't bothering right now with the demonstrator. They aren't using EJ200s for the actual GCAP, but something bigger.

And iirc there are indications FA-XX won't be especially super size.

If it cannot carry 4x GBU-31s internally, what's the point of buying FAXX versus more F-35Cs?

They specifically said they aren't aiming for a very high TWR for the eventual fighter, not for the demo.

Why are 4 GBU-31s internally so important? The goal is to replace F/A-18E/F; why not 4 blackbeard/jsow?

Because the GBU-31 size means JSMs also fit.

Though I suspect that the real dimension is now AIM-424s, which should fit into a box 20" square by 14ft long. 4 of them, maybe 6.
