honestly if you ask me, the H-6 is way too old and does not contribute much to the strategic bombing role. The most it can carry is 2 cruise missiles or something similar. one might argue that the U.S. have been using the B-52 for almost half a century now, but do realize the B-52 got a much larger payload and range than the H-6. as of today, the most useful role for the H-6 is its air refueling capability for the PLAAF and PLAN, other than that, I don't see any other practical use that can not be substituted in by other PLAAF combat aircraft. China needs its own strategic bomber and tanker!
