Advantages Of Wedgetail?

Fri Jun 14, 2002 3:50 am

Hello, does the new 737 Wedgetail AWACS have any advantage whatsoever over the present AWACS and 767 AWACS or not? It seems like its more modern, ie no moving radome but I could be wrong thanks!

it's cheaper...
I think the proposed 767 AEW&C will be more powerfull and have longer endurance, but cost would be prohibitive for smaller countries.

See the 767 as an E-3 replacement, the 737 as an E-2 replacement (for landbased use only of course) and you'd not be too far off the mark.

just a note on the E-767

THe systems IN the E-767 are the same as the E-3C the RADAR is the same AN/APY-2 that is in the E-3C (the 2 has better maritime capes than the APY-1)

The reason Japan got hte 767 airframe was that Boeing would not start up the 707 production line for just 4 airframes. So 767 it became.

actually Generators are a problem on the 767. the E-3 has 4 engines (plus the aux) with 2 generators a piece. While the E-767 is much harder to get internal power from.

The wedgetail is a phased array radar versus pulse, dopler and BTH systems. So the difference is coverage area and MTI-moving target indication is a little different and there is not a doppler notch (so to speak) the same as on a simple doppler system.

also there are fewer consoles and controllers on the wedgetail, so it has less Battle Management capes, and no Electronic Combat.PDS system like hte E-3 (US,NATO, UK).

Didn't Japan plan to upgrade its E767s with indigenous phased array RADAR and other electronics? Or was that program shelved?

I've read of many planned changes or upgrades but right now all 4 JSDF E-767s have the An/APY-2 like 10 of our (USAF) AWACS.

Cheers. Now to get a replacement for the old E-2 in carrierservice (and for the E-3 over time) started. With current development cycles it'll take 20 years to get them in service by which time the current models will be very old indeed.

I doubt it will replaced the E-3 as the 767-400 is surpose to both the E-3 and E-8 I might be wrong on this if so please let me know.

a 767 airframe is under development to combine several aspects of the E-3, J-STARS and even Rivet Joint. on a 'super HVAA'

"The MC2A is being designed to replace the RC-135 RJ, E-8 J-STARS, and AWACS aircraft and, as an added benefit, to spot stealthy targets such as cruise missiles. As posted in an early tactics update the first testbed flew Apr 18 at Hanscom AFB, Mass. The plans also allow for the aircraft to carry a forward deployed airborne JAOC to give it combat ops capes for controlling global strike task forces. The testbed a 707 airframe nicknamed ‘Paul Revere’ is to eventually be replaced in the new widebody B-767. See AWST 29 Apr pg 32"

Those of us flying the E-3 don't see this as the best option but time will tell.

the E-767 (which has the same Radar as the E-3) is not the same as what is being developed above. The Wedgetail would have more similar capes to the E-2 Hawkeye 2000.

I agree having a single platform for everything is not good.
Not only will there have to be too many compromises, it will also be a much more inviting target and the budgethawks will say that as it can do the job of 3 types, you need only 1/4 of the total number of those combined fleets.

I didn't say that it was a good idea, personally I think it is a bad idea.

I have to agree, there seems to be an awful large amount of missions to be putting on one airframe.

I have to agree maybe a smaller country could get away with that sort of thing like Australia but not the USA.
