I mean I get it that their most major radar company RTI and most major EW company KRET state 10 years behind the west in MMIC technology.
Nobody knows that. They have minitiarized their AESA tech enough to fit into missile seekers, which puts them on par with Western Europe.
But I mean you were given more than 10+ years to have improved modules like their biggest rage of mass producing LTCC modules for lower AESA costs and heat resistance. But instead the aircraft is just a downsize of the already existing N036 radar. Better off sticking to Su-57s for domestic production or go serve your pilots as cannon fodder with these aircraft. Now I am just sticking around for the export potential of it. Is it still too late to create a new airborne radar platform?
The LTS is meant for export. It hasn't been developed for the Russians.
There's nothing wrong with downscaling their existing tech. The jet has been designed to accept export grade tech developed for the Su-57. The problem is how well sensor fusion developed for the export market around a new ICP will actually work with it.
The Russians are offering the jet for joint development, which means the avionics are subject to change as per customer request, as long as the order is big enough. But most air forces will be fine with downgraded PAK FA tech since the jet is meant to be a cheap next gen workhorse.
I suppose its western equivalent would be what the USAF plans to develop as the F-16 replacement later on, as long as it comes with IWBs.
