But still in validation and developing doctrine to make it fully operational. It is in initial stages in 2 regiments and still with testing units also.
In service = fully operational.
If you have evidence that all J-35A are still with test & evaluation rather than combat units, please present it to us.
Technically speaking J-35A is probably at the equivalent of IOC or late IOT&E at present; we know that it is in service with one frontline brigade at least -- however,
@Mekconyov, you wrote "It is going through testing, evaluation, validation and would proceed to initial induction. Later on would go to operational regiments."
J-35A is already in service with an operational brigade.
It is true that J-35A is yet to reach FOC, but you are also categorically incorrect in your previous post that it has yet to reach an operational unit.
As others have said, you need to either stop posting, or write things more specifically, or both.
Because that post and your prior post actually contradict each other.
Your post in #2188 only talked about how it has yet to reach an "operational regiment," which is false as we know J-35A is in at least one frontline operational unit. Your post in #2191 said how it isn't "fully operational" -- which is true.
I hope you realize that an aircraft can be in service with a frontline operational unit but not yet be "fully operational"/FOC??
