Paralay's vision of NGAD

[paralay]

The expected dimension of a promising fighter. The contours of the YF-23 while applied as the closest in volume. The right is inscribed in the dimensions of the lift of the aircraft carrier "Gerald Ford".
The second stage engine for the F-35 fighter will be the first stage engine for the promising F / A-XX.
Expected afterburner 20500 - 21500 kgf, 10% higher than the serial F135.
Take 47,000 lb / 21320 kgf

The predicted thrust-to-weight ratio of the sixth generation twin-engine fighter is no less than:
normal take-off weight 1.25
with a maximum take-off weight of 1.0

From here we get the maximum take-off weight of 21320 kgf * 2: 1.0 = 42640 kg, the normal weight of 21320 kgf * 2: 1.25 = 34112 kg.

Normal take-off weight F-22 * 1.5 = 33324 kg (75,000 lbs / 34019 kg)
The maximum take-off weight is F-22 * 1.25 = 42382 kg (94000 lbs / 42639 kg)

The 300-foot (91 m) LIM EMALS (aircraft carrier Gerald Ford) will accelerate a 100,000-pound (45,000 kg) aircraft to 130 knots (240 km / h; 150 miles per hour).

The radius of action is 38% higher than that of the F-22, that is, in the region of 1200 km (in-in) / 1640 km (in-s)

The volume of the load compartments is at least 8.6 - 11 m3 or 1.5 times more than that of the fifth generation fighter. Maximum combat load 42382 kg * 0.26 = 11000 kg

How would that configuration deal with the low speed approach requirement? Wouldn't the canard configuration be more appropriate?

"Duck" is a great scheme if it is from an enemy aircraft

I'm honestly expecting two separate aircraft for the USAF and USN NGAD/FAXX bids. USAF will very likely be over 100klbs, FB-111 sized or so.

For the Navy, though, steam catapults max out at about 85k-88klbs throw weight, and IIRC the old arresting gear has a max recovery weight of about 65000lbs. And the Nimitz class will still make up over half the carriers in the USN till sometime in the 2040s, maybe even 2050s. 8 years between CVN78 and 79, which suggests that it will take close to 40 years before there are 6 Ford-class in service. That's 2057 or so to get 6x CVN78s in service at 8 years between commissionings, and means that the last Nimitz won't leave the fleet until something like 2097...

The weapon bay needs to be enlarged

Where this shape come from ?

This is a compilation of several well-known images of a promising fighter. This layout does not have enough volume for the declared take-off weight and promising engines.
I assume that the F/A-XX and NGAD programs will be combined into one. The fighter will probably have a V-shaped rotary tail and a variable geometry wing, for example, like the XB-70.

I strongly disagree. The USAF needs a lot more range than the Navy does, and the USAF does not have the weight limits that the USN does for carrier takeoff and landings.

The F/A-XX cannot exceed ~85,000lbs MTOW from the carrier due to catapult limits and cannot exceed ~55,000lbs landing weight due to arresting gear limits. The landing weight restriction means that the effective max empty weight is ~45,000lbs, bringing back all missiles and enough fuel to allow at least one missed approach before forcing the pilot to hit the tanker.

NGAD could happily be F-111 sized, 105,000lbs MTOW. Or even larger, for a "Strike NGAD" that packs some 20,000lbs of boom instead of 3000-4000lbs of air-to-air missiles.

A country printing dollars can afford to have two heavy fighters in development, if someone still needs dollars. But the situation in the world is changing rapidly. As I understand it, the financing of NGAD is already in question, at least with a three-circuit engine

 

[VTOLicious]

On the other hand countries with much less economic power are developing an indigenous 5th generation fighter, associated equipment, engine and CCA (e.g. Turkey)... However, US armed forces have a lot of other stuff on the shopping (wish)list what eventually is the real issue.
