US is still using the B52s til 2030 in similar roles - cruise missile launcher. I say China is making a wise choice using a proven airframe, and spend the $ on R&D for other projects. One H6 with a total of 6 missile is nothing to sneeze at.
Production of Vulcan and Victor ended in the mid '60's, nearly half a century ago.
B-52s were built from 1954 into 1963. Almost ten years and 742 aircraft were built. The last 14 were built in the first half of 1963. That's over fifty years ago when they were built.
Since that time it has all been maintenance, maintenance, maintenance...and modernization within that large airframe.
So, the important issue is not so much when they were last built...but how well were they built, how were they used, and how well were they maintained.
The fact that the B-52 is still flying in relative good numbers, and will continue flying now, actually raygun the plan is for them to fly into the 2040s (another 30+ years), making them well over 85 year sold when they are retired, tells you that they were well built, they have not been abused, and they have had very, very good maintenance. In addition, because of the continual upgrade to their sensors and weapons, they are still relevant.
Now, the new H-6Ks are not vintage aircraft. These are new builds. They are built to an older airframe design it is true, but they use newer, better material, and have new wiring, electronics, etc. Of course you can see the H-6 and TU-16 heritgae in them. But in a role similar to the B-52...even though their number of ALCMs is much smaller than the B-52, they will still perform very well, particularly in numbers, in that standoff role.
Here's a number of pictures of the venerable old aircraft...the first three flying to this day:

Current B-52H of the US Air froce
Current TU-95 Bear of the Russian Air froce
