I am struggling, it has to be said, to find a rationale for deploying the Potemkin 
There is no rivers deep and easy enough to sail!
the only significant lake is "Karakul" and I do not find it of strategic importance.
So, the only way if you really need a vessel, transport it in prefabricated parts and built it inside the lake [I suspect that the Karakul city has some facilities].
I saw also an airport, surprise, by Kashgar
I am afraid that it will be beeter to use your airpowerr!
