Do you have a source? Those numbers seem a bit off.
Fuel increases from clean to max. by a factor of 2.6
Range increases also by a factor of 2.6
That would suggest the CFTs and drop tanks have no drag/weight penalty at all.
You are correct about that. The basic internal and with CFT ranges are higher and the gains from ETs are lower than quoted.

Are you talking about F-15 or that Su-27 pic?
Su-27. Sorry, the translator can not understand complex sentences.

Precise data on the Internet has been found. This calculation, based on the available information, it requires clarification.
The data for the F-15C:
Flight range F-15C (DT - hanging tank, CFT - conformal tanks):
Without DT (6105 kg) - 2200 km
1 DT (6105 kg + 1800 kg = 7905 kg) - 2850 km
2 DT (6105 kg + 3600 kg = 9705 kg) - 3500 km
3 DT (6105 kg + 5400 kg = 11,505 kg) - 4150 km
CFT (6105 kg + 4265 kg = 10,370 kg) - 3700 km
CFT + 2 PTB (6105 kg + 4265 kg + 3600 kg = 13,970 kg) - 5000 km
CFT + PTB 3 (6105 kg + 4265 kg + 5396 kg = 15,766 kg) - 5680 km

Clean, the F-15E has after all almost the same range as the A-D model, a jet not usually known for its short legs.
Not sure, they have 20% less thrust with higher BPR, more fuel (C/D) and a lighter airframe - at the very best, it might approach the capabilities of the A/B model. While the Albino Eagles have decent range, they're not exactly class-leading - apart from having less payload the much smaller F-16 does almost as well, so an F-15E without CFTs will have very short range for its size.
Its saving graces compared to the MiG-29 would be the ability to carry drop tanks and refuel in flight.

The latest air international issue shows a F15 test firing a JASSM. It's hard to tell for sure from the picture, but it appears to be carried on the front CFT stations.
I have two questions related to the F-15I Ra'am variant:
1) How many Popeye missiles can it carry?
2) What would be the range (approximate) with two AMRAAMs, two Python IV AAMs and (say) 2 Popeyes (if it can carry two), plus all internal fuel possible with this loadout?

By similar weight to the F-15E it generates 3000 km range from 9640 kg fuel or ~1640 km range from 5270 kg fuel at least.

If you are talking about this photo:
http://www.lockheedmartin.com/us/news/press-releases/2012/july/mfc-072612-lm-completes-JASSM-F-15E.html
It clearly came from the center station.
Btw, it was done via UAI.

I think this might be close to the combat load of a flanker for there are several pictures of it flying in more or less this exact loading.
