Every aircraft development program runs into problems at some stage. No big deal, especially when it comes to the high level of engineering present in
a fifth generation fighter aircraft like the F-22 and PAK FA.
The main problem addressed in the article is the engine. NPO Saturn is trying to develop the AL-41F supercruising turbofan, equivalent to the PW F119.
Developing a jet engine is a complex task, as it requires the correct metallurgy, along with precision-made engine parts and correct level of tuning
for optimum performance, along with reliability, maintainability and fuel efficiency.
Given the high level of engineering, such a 5th gen fighter may not be produced in bulk unless the aviation industry is sufficiently large enough to
allow it.
