That aircraft looks far too big and bulky for the Varyag and its ski jump popeye. Anyhow, as I understand it, that Yak (Russian) aircraft is just a mock-up...but am still waiting for further verification of that.
I believe if the Varyag does get any AWAC capability, it will either be a helo based platform, or perhaps some kind of VTOL platform.
As I indicated to another poster, US would do well, and has studied, creating an AWAC version of the V-22 Opsprey. They would work well on the Amphibious ships in conjunction with the F-35 JSF.
Just my opinion.
By the way, I would be interested in your input/comments on
this thread about my recent trip over to Bremerton.
