Awacs Weight Changes

Wed Aug 04, 2004 10:31 pm

It was a pleasure to see this nice shot by Stephen Fox of 1407, the prototype AWACS:

It's hard to believe that it first flew over 32 years ago! At any rate, seeing it in its upgraded E-3B form made me wonder about weight gain over the years. Does anybody here know how much the ESM equipment, additional consoles, IR jammers, etc. have added to the empty weight? Has some of the additional equipment been offset by (lighter) computer upgrades?

That's a good question. The baseline E-3B, has the APY-2 radar, CC-2 computer, ECM voice resistant voice communications, 14 situation display consoles, Have Quick secure comms and self defence AAMs. The E-3C has 19 consoles and the 'Have Quick A-Nets' comms. Anyway, the weights for the E-3B are as follows: empty 77 996 kgs (171 959lbs ) , MTOW 147 418 kgs
(325 000 lbs). It doesn't answer your question, but gives you some idea how the 'average' Sentry tips the scales. And as for the AAM capability- I'm betting the only aircraft the E-3 could down with a 'winder would be an An-225. Still, it would be an extremely gracefull furball to watch.......

LOL that really puts things in perspective. "MTOW 147 418 kgs
(325 000 lbs)".
thats less than our fuel capacity of 332,500lbs.

And 332,500 pounds is less fuel than the 10's 340,000 pounds......

Yet, who can fly further on that gas?  Smile

I work on the RAF E3D awacs and we have recently had to install ballast weights in a redundant compartment in the front of the aircraft to counteract the change in aircraft centre of gravity from the change of systems and equipment the aircraft have experienced and may experience in the future.

Well with 330,000lbs we can usually fly direct from Kuwait to Travis.

Yeah, with no cargo. In the gulf war the 10s went direct Saudi Arabia to March non-stop, un-refueled.

What's your average fuel burn per hour?

how did I miss this topic anyway...

Chesire- the E-3B does not have the AN/APY-2 it still has the AN/APY-1
We have ten C models with the -2. The Maritime cape that comes with the AN/APY-2 ads very little extra weight. Both US B and C models have 14 scopes, no AWACS have 19 consoles for control.

There is no major weight changes from the A to B/C models even with the PDS changes, because RSIP has reduced cabinets and weight inside the aircraft so the change is nill.

The biggest increase in weight is when we add the 4 J-Compartment seats, with 4 more pax and/or gear.

Computer and radar weight has not changed fromthe A to B/C models. Our MGW can be over 340K .

The Brit E-3D with 9 consoles is getting the 5 extra consoles which will ad extra weight. Now the E-3D (which I have flown on) with the newer CFM-56s can take off with higher weights than the US E-3B/C

E-3 AWACS with a AAM?!? Can anyone confirm this?

I've been around a while and have yet to see an AWACS with a AAM. Where's
the launch rail?

Chesire is incorrect that there are aams but...

As for hardpoints, the original does have 1 hard point under each wing, but it has never been used other than for testing on the Boeing bird in Seattle.

Lt-AWACS,

Thanks for the confirmation... The rest of his post seemed pretty knowledgeable. Seems everytime I see a E3 it's got new "warts & bumps" and I don't ask what for... but a launch rail... whew, that would have got my attention...
