After re-reading "Bullets and Bluegrass", it is my impression that the KFS uses multifuel rotary engines for all its vehicles (including the V300, the Bradley and both M60 and M1 tanks. I assume that these "rotary engines" are based on a version of the Wankel engine
(Bullets & Bluegrass page. 9 "All Army and Air Force vehicles use multifuel rotary engines capable of running on virtually any flammable fuel)
However, the powerplant used by the P47 "Thunderbolt" is unspecified. It may simply be a copy of the Pratt & Whitney R-2800. As far as I know, nobody has built a wankel engine with enough power to replace the R-2800, but it may be possible.
I did a little work on a KFS helicopter unit

and this is to "rescue" crashed planes

I'm sure that the KFS military would REALLY like a versatile twin engine transport, like a DHC-4 Caribou or even a DC-3 Dakota - but these are not cheap...
Also, it might be amusing to have the KFS build its own hovercraft. "If the Morrow Project has them...We should have them!"
The KFS probably has the capability to build a sizeable hovercraft like the the API
