I found this. F-22 "classified range" found on some LM article I found, and aparately it's no slouch. Official combat radius of around only 750 km which is low because of supercruise for a long time at 100 nautical miles. However with tanks it can go up to 1600 km even on ground attack configuration rivaling the Rafale. I know tanks might compromising stealth, but the F-22 superior sensors can get the first look or jettison their tanks and pylons before combat starts.

F-15E combat radius with 2 bombs not so much even compared to the F-22. It just shows a fighter that can go 1900-1200 km combat radius is severely degraded by drag of his missiles, targeting pods, and bombs.

If F-22's combat radius is up to 1600 km with 2 JDAMs, it's air-air combat radius much greater. I believe the official combat radius of the F-35 is <590 nm for the A model, but can go up to 1350-1400 km on air-air mode. How much does range degrade with just internal loads between an AAM and bomb?

It's surprising the F-15E combat radius is so degraded by bombs in the chart. Isn't the F-15C combat radius 1900 km, and the F-15E around 1200 km?

Huh? Where are you getting this from?

<590km? Look again.. closely.

Yeah I meant nautical miles sorry.

The chart requires you to look closer to see why the range is degraded for the F-15E.

First. HLLH on the chart. High-Low-Low-High altitude flight profile. A low level ingress and egress will drastically reduce range.

Second. 30% routing factor listed below the chart. That means an extra 30% of the listed range is needed to avoid the worst air defenses.

What the chart really shows is the advantage of stealth in that you can waste less fuel on threat avoidance.

A consequence of being non-LO. Similarly a Su-34 is a humongous jet with a rep for long range but when it has to fly a similar flight profile to help evade defenses, it's combat radius is less than impressive.

That's the F-15E going around threats both ingress and egress, using 30% of its fuel to do so. F-22A using 6% in comparison. Also note the F-15E and F-117A have to close in nearer the target to deliver due to the weapon choice. F-15E can deliver standoff weapons, so the chart is disingenuous for that. Eurofighters, Tornadoes, and Rafales would be delivering multiple standoff missiles which would make them appear highly advantaged over the stealth options using the same disingenuous circumstances.

The Lockheed document says "greater than" 590 nm.

The latest DoD estimate is 625 nm. This would be with the standard config of 2x 2000 lbs bombs, and 2x AIM-120.
In an air to air config (and mission profile), the Lockheed presentation to Israel claims 760 nm. Both numbers are impressive for an internal fuel load.

As others have said, the HLLH profile for the F-15E makes a HUGE difference. If the F-15E were flying with 3 bags, in an A2A config (much lighter) and flight profile (higher, more efficient cruise), it would be a whole different story.
