Yes, but for this a Y-9 variant would be more than enough ... so IMO a Y-20 gunship variant is nothing but a fan-boy phantasy.

From Oedo blog any truth to it?
Y-20B equipped with WS-20 engine makes its first flight this year The current Y-20A engine is WS-18, and the H-6K engine is D-30KP-2.

It does not say it fly with WS 20 yet but will be this year They have been testing it on flying test bed for years now So why it is so incredible?
I think the point is simply that - at least by me - I would have rated the WS-18 as dead.
Well, it would be incredible because people seem to assume just because an engine is older that it would somehow be easier to replicate. It would not.
The D30KP is a turbofan engine. It is quite complicated. Just the high pressure section has 11 stages. Compare that with the WS-20 where just the low pressure section is new. The rest is leveraged from the WS-10. Unless the Russians like just physically transplanted the D30KP factory to China I simply don't see a WS-18 happening in that sort of timescale. Even if they did something like that it could easily take 3 years at least if not more.
So I would not be surprised to see an Y-20 with WS-20 flying this year. But the WS-18 just smells of vaporware and pixie dust.

There is also the fact that the Chinese are currently developing two engines in that thrust category.
Both the WS-20 for the Y-20 and the CJ-1000A for the C919. So why a third engine based on 1970s tech?
Even the Russians are switching to the PS-90 and even more modern engines based on the PD-14.

CJ 1000 is airliner engine and not meant for military application. It is not unusual for Chinese military to undertake 2 military development simultaneously as fall back option. If anything it is the norm We can see from ships type 51 and type 52 Myriad missile program and IFV The looser in the competition normally will be offered for export
China only import around 150-200 D30KB from Russian sources There are 50 H6K that use 20 of them so total usage 100
There are around 20 Y20 assuming it used 4 D30KB Another 80 is now used So where are the spares?
And we know both H6K and Y 20A are now produced in large number So where are all the engine come from ?Unless China import more from Russia which we will know because the Russina will tell the world

Ouch... except a few countries have been buying similar types for domestic use.
Counter insurgent operations don't require an occupation. They just require insurgents. Or perhaps just occupation of a province that doesn't obay the will of the capital.
