KJ-600 carrierborne AEWC thread & possible KY-600 (?) COD aircraft

Does the two tone color of the rotodome indicate KJ-600 uses a single rotating aperture instead of three fixed apertures that soem other rotodome equipped Chinese AEWACs? Presumably the aperture underneath is electronically scanned, and rotodome rotates fairly fast to minimize tracking time gap.

Single rotating aperture BUT.. if sector scan is needed, the rotodome can be stopped to cover the intended area, subsequent scanning is then carried electronically.

Interesting, so it's not possible for the KJ-600 to take off from type 002&001?
Shorter deck and no assist makes it difficult and risky. You'll probably need the entire deck to be able to launch it so it might not really be worth it.

I mean, if push came to shove, you probably could but is not something you want to do on the regular. Plus recovery is another thing given, again, the shorter deck to take on a heavier aircraft.

E-2D's recover regularly on Charles de Gaulle which is smaller than 001 or 002 so that's not as much of an issue as launch. However, if launch was possible then why aren't we seeing E-2s launching off QEC and various other CVs equipped with poverty ramps?

Because the ramps aren’t the only thing poverty about the RN these days and they just couldn’t afford any E2s?

It's not just the RN that uses cope slopes. India, Italy, Spain do as well. You'd think India at least would have investigated the possibility as their CVs have arresting gear.

I have suggested for some time that pairing up 001/2 and a 076 when needed would give them a massive boost as the 076 can carry a couple of KJ600s, UCAVs and helicopters to allow the combined group to field a full spectrum air wing as well as bring more airframes to the party, and I think that would have been part of the 076’s design requirements from the get-go, as the synergies are just too obvious and beneficial to miss.

Italy and Spain aren’t expecting to actually use their carriers for near peer combat. Hell, I doubt they have many realistic operational plans to use their carriers in combat at all, and most certainly not without direct US support, so why buy E2s when America can shoulder that burden?

As for India, well, are the Americans prepared to export E2s to them for that to even be an option?

Launch is possible based on many conditions: takeoff mass, runway length, thrust to weight ratio, minimu ramp to sea level height etc. Many other ski jump CVs lack this or that condition. QEC has a very narrow ski so it doesn't have the safety margine but then it was made narrow because UK didn't or couldn't operate E-2. In other words, if UK really want to operate E-2 QEC can be made to do so, provided that E-2's front landing gear has to be redesigned.

Particularly regarding ramp takeoff of AWAC, China has done studies many decades ago and conclusion was that "if parameters are right, it will work". The reason of not doing it has little to do with tech but more to do with "does it worth it?"

Could be argued the CdG was designed with the E-2 in mind so the arrestor gear could compensante for the shorter deck, though, since the planes were basically bought with the CdG in mind and the Clemenceaus could never launch/recover anything bigger than the Alize/Tracker.

Also there is the whole thing about not operating fixed wing AEW aircrafts, by the Cold War, RN was using Sea King based AEW so they never had a requirement to be able to launch E-2 sized planes
