Interesting reading. Sadly, once I encountered this, I realized the article was extremely biased. The USSR successfully achieved this several times.
I suspect this article will age badly after WS-15 goes live. China has significantly narrowed the gap.
By going live, I meant when WS-15 is integrated with J-20 rolled-out in a fully-operational and mature manner. This is expected to substantially close the gap with top U.S. fighters in raw propulsion performance.
