Su-33 has a very potent airframe, yet
it's a junk given outdated avionics and radar it currently has...
Naval Tejas, assuming it's MK2, not MK3, 4 or 5,
,
is a virtual junk, literally, which would never see the daylight once it's close to 2040 when India (DRDO/HAL?)would take it offline as per their usual daydreaming habit by drawing up a new plan of Tejas MK8 with 6th-gen AESA and 3 laser guns and so on on...
Mig 29 and Mig 29K are about
THE actual junk of all modern planes that Soviet/Russia have ever made in the last several dacades. The miracle that this short legged (read: half-retarded) creature is still alive today is completely due to the even more miraculous Indian IQ and stupid money coming with it.
The possibility that Russia's CV would use Mig29K in the forseeable future is to piggyback the benefits of Indian investment, sure why not, after Indians have "given" them a brand new MIG 29production line FOR FREE
---- the upgraded Mig29K is surely better than 12 museum pieces of ancient Su-33 despite its airframe, isn't it?
J-15, however,
is the most potent naval plane in the group, by a HUGE margin: it has Su 33 airframe, J-11B level 4.5 gen avionics/radar, the longest leg and heaviest weapon load. it can hold its own against Rafale M in most circumstances, and under certain conditions (e.g. pure airsupeority) it could even have an edge over a F-35.
