The IRST of the T50 is bulging out of the airframe, the same way as the EOTS does at the F35, the only difference is, that the EOTS has shaped windows and if that isn't a requirement for the Russians currently at their early version, that's up to them, just like how they want to use the early Pak Fa in in strike role, because that decides if the external LDP makes sense or not.
Absolutely agree. The Russians have designed the pakfa according to what works best for them. My reference was to the Pakfa MKI which we are buying (FGFA) and which apparently is still in the design phase with us having submitted 40 design changes, and in the development of which we are equal partners.
The F22 AND the F35 will primarily use satellite guided weapons from stand off ranges in the first days of a war.
The F-22 will use the JDAM and the SDB because it lacks support for a LGB. The F-35 will use the 1000 and the 2000 pound LGB for lower number of targets that require heavier stuff, and the SDB II which has the laser guided mode for the smaller targets giving it more targets per sortie.
Laser guided weapons like LGBs or ATGMs on the other side would be too risky because of the low range and the fact that most heavy LGBs doesn't fit into the weapon bays anyway.
The F-35 can handle 2 x 2000 lb bomb, which is exactly the same number of 1000 pound bombs it can carry. It will use the EOTS and DAS for targeting, BMD and destruction for targets that require that sensors be put to detect and track them.
That means the EOTS mainly will be used in CAS, when the risk is low and full stealth capability is not required
CAS is important for EOTS, but so is SEAD and DEAD especially with the IAD threat projected. Its a discriminating passive sensor which can be relied upon so that the use of SAR and ISAR image is restricted to a minimum.
In fact, it is even likely that it will use it's external stations in such roles too, to increase the weapon loads or add more fuel to extend endurance.
External stores are likely when the mission demands, it is certainly going to be cleared to carry external weapons with the full block 3f capability.
just like an F22 would do it if it would carry LGBs.
The F-22 would not carry LGB's, if it does carry the SDB II it would use it not through a laser pod but either using MADL or in non laser modes.
So an integrated EOTS is not always an advantage and used as a compromised IRST it's even a bad solution, compared to the OLS of the Russians. But without this IRST mode, the whole system would just be added weight, drag and most likely RCS during A2A roles, where it's not need. But A2A roles are what the PaK fa or the F22 are primarily meant for
I was speaking form the Indian side given that the PAKFA is going to be our main long range stealth aircraft for a long time.
