The F/A-18 SH (E/F) is a much more advanced version than the F/A 18 Hornet (C/D). The only reason the US Marines are not using the SH is because they had a lower budget
Agreed, but the Procurement was ceased coz the Marines are more interested in the F-35, and do not want the Super Hornet to eat up the Funds & further delay the induction of the F-35.
Also, then following your logic, IN should opt for the F-35 program and wait for 10 years before the first one is delivered. Which means, the IAC2 and IAC3 will be sitting idle for 3-6 years without a proper aircraft to fit into it.
Our Defense Minister Mr. "AKA" has already publicly rejected any participation in the F-35 Project, so the Logic does not stand.
The Indian Navy has already invested handsomely in the MIG-29k & the Navalised Tejas, they are also looking out for the Rafale & the Typhoon. so my friend the IAC2 & IAC3 will not be sitting idle.
The F-35 naval versions will be delivered from 2018 onwards.There is no prototype of a 6th gen fighter flying anywhere and no way will the US congress let a multi-Billion dollar F-35 be replaced by a 6th gen fighter as early as 2025. The F-35s will be there till 2040, at which point, the 6th gen fighters will come in the USN. The USAF may get the 6th gen fighters sometime sooner (to replace the F-22s), but even that is not certain at this point.
Yes there is no Prototype ready so that does not mean to project is not conceptualized, Russia & China are fast closing in the gap and we will soon see them upgrade their fighter jets to the 5th Generation. (even India & Japan are attempting to have their own 5th generation Jet)
So do you think the US will be left behind, the race never ends when you are the only Super Power in the world & see others catching up with you.
Infact the time gap will always reduce, from one generation to another. coz technology is volatile, there are countries cutting the technology gap & how can US be left behind..
& no one is perfect, i can also be wrong with my logic...
