I’m guessing that WS-10 is more concerned with mass airflow and probably has decent dry thrust fuel efficiency compared to Al-31. I wouldn’t doubt it’s problems lay in the afterburner.

Wings don’t look wide enough to be the Reaper. Also it doesn’t have much payload. They load up Reapers for kill missions, Predators do the ISR.

The problem is the source is a propaganda site masquerading as a news site.

The development stage is late enough for variations for each model. If the USAF requires more wing sweep – which isn’t a problem – it would have happened. Quite frankly the F-35A will airframe on airframe fly more supersonic than any of its predecessors bar F-22A. Every single F-22A has probably surpassed the supersonic time of all F-15A combined. Supersonic jets really spent almost no time above Mach until the fifth generation.

Kamov helicopters are rugged. I see no reason that teething issues should be worse than on any other product. The parts of them are actually no more complicated than on single rotor multi blade assemblies, and they don’t require any larger ground crew.

I’m pretty sure F-16 flies better with a load at the wing tip, whereas unloaded wingtips oscillate more rapidly. The movement can have an adverse effect on the already difficult accuracy of unguided munitions.
