As far as I have been able to find out, the E-3F is fitted with CFM56-2 engines...

Cheers,

And yes, occasionally they do scrape the bottoms on cross wind landings...Just like the DC-8 does.

By the way Hawk21m, E-3's never had JT3d's except for the first 2 prototypes and they were commercial built 707's (EC-137D's)with rotodomes stuck on them. The Usaf and Nato E-3's have the TF-33-PW-100A Pratt Whitney Turbo fan. It is more or less a modified JT3D from hell. No thrust reverser, turbo compressor or sucker doors on a oversized intake whick give it more 4000 pounds more thrust than a JT3D which is about 17000 pounds at sea level. Also the -100A has 2 bleed valves to help with acceleration.


I would help you but it is not in the contract

And the Brit 56s give them the ability to go higher and takeoff heavier (slightly) (though the AN/APY-1/2 RADAR is optimised for normal E-3B altitudes).
US E-3s will not be getting new engines any time soon, if ever, certainly not on the upcoming 40/45 mod.

To Lt Awacs, just getting TCAS would help be great help than going across the pond under 29000 feet. After 77-0354 went down in Alaska you would have thought getting better engines would have been a priority.

29K is standard we normally don't go lower than that for Radar ops. As for TCAS each and every AWO/WD on the flight is "human" TCAS with a lot longer range than TCAS, using the radar for what we call "AWACS monitor" anytime the radar is on we tell the flight deck abot traffic.

The Yukla incident has been flown and reflown upty-frat million times in the sim, and some say newer engines wouldn't have mattered. I don't know, others say if it happened at TInker the plane could have done a go-around but the mountains at Elmo prevented that.
