If hes still around, would you mind asking him about some fuel burn-rate data? I figure anyone who flew one or worked on one oughta know.

I Have a FM for the F-4-E, give me a day or so and ill dig up the exact flow rates
Dont remember them but at Full Blow its scary

Thanks! Im just looking for how long (in minutes) the fuel lasts at various burn rates. And thanks for trying b56!

I only know that we put about 2500 gallons onboard an E to fill it with
2 wingtanks, when it came back about 2.5 hours later we did it again. I
worked the pointy end, not the noisy end..no idea what burn rates were.

Thats actually very valuable. Did the plane have more than those two wing tanks? And was that for combat runs? Or just ferrying? (Im sorry, im thinking maybe I can do some calculations and guestimation myself...)

That was full internal fuel plus 2 370 gallon drop tanks. Our missions
in the early 80s were generally air-mud at the ranges at Eglin in northern
Florida or up in northern Georgia somewhere.

Moody AFB is just north of Valdosta, Ga, so travel time to the "target"
was not very excessive.

Where can I get a fighter in AHII that climbs at 41K/minute?

Good discussion. The F4 was my favorite jet until the 16 came out.

GE J79 fuel consumption...

Sorry it's Wikipedia...

Best Regards, and get some sleep.

[edit] If the mission called for supersonic flight, then the plane would only carry the centerline tank, and not the two wing tanks. For long ferry flights all three tanks were on.

Great! Thanks! Im trying to guess just what a 'Long' flight is, because all of the testimony I can find is vietnam combat, and they almost always seemed to carry the wing tanks. (Or at least all of the action reports Im reading seem to have them) Thank you SO much! School starts again soon, and ive barely slept all brake. I get really obsessive about these things, almost unhealthily so...

edit: Just read through that. It only lists fuel consumption with afterburner. Is there some mathmatical equation I can use to find out at different burn rates?

Fact sheets

Go down to F-4s and check their performance.

CAP for a D:

PERFORMANCE for Combat Air Patrol (CAP) Mission:
Four AIM-7 Sparrow missiles, one 600-gal. and two 370-gal. external tanks
Combat altitude: 40,000 ft. maximum
Combat speed: 1,178 knots at 35,000 ft. maximum power
Combat weight: 36,140 lbs.
Combat radius: 250 nautical miles
Mission time (CAP): 2.48 hrs total; 1.39 hrs CAP

(the Combat speed would appear to be the combat MAX speed, and the 2.48 hours total would appear to be where most of the flight is cruise at about 550 knts, since the following is given for the F-4C)

PERFORMANCE:
Maximum speed: 1,400 mph/1210 knots at 40,000 ft. maximum power (ferry mission)
Cruising speed: 590 mph/546 knots at 35,000 ft.
Range: 1,750 miles/1528 nautical miles ferry mission with one 600 gal. and two 370 gal. external tanks
Service ceiling: 59,600 ft.

Great! Just what I was looking for! Thanks so much!

I read a book about an F4 pilot in Vietnam. He said that on bombing missions, the F4 would only climb at about 2000 feet per minute when loaded with bombs.
