There's no doubt they and everyone else is lagging behind in engine tech.
But the B-47 had a 2,000+ mi combat radius with a whopping ~40,000 lbf thrust from six inefficient engines. You don't need AETD engines to build a
strategic bomber. The H-6 gets by on two inefficient engines. Two engines in the 25- 30,000lbs thrust range with a decent bypass ratio probably isn't
out of the question very near-term.
The WS-15 is supposed to provide 23,000 of dry thrust. Give it a bigger fan and optimize it for a lower velocity range, you could push 30,000 lbs
with out too much hassle with a better stfc. If you believe the WS-15 is close to ready, so is a derivative of that core. And a bomber engine takes a
lot less abuse, so if the WS-15 is robust enough to move forward, they are real close.
Will it be cutting-edge efficiency and performance? No. But even the WS-15 itself is plenty of engine to mate to a twin-engine bomber with range.
