i must say i can't any examples where a scout helicopter or even a light attack helicopter had a mast mounted radar. This is a first, and it is a bit perplexing.
I expected a scout helo to have mast mounted electrooptical sensors, but not radar. I expected to find mast mounted radar on z-10, but even though it is older helo than z19, it didnt get one, but its younger brother did. Strange.
I guess that may point out that z19 isnt so much a scout helo as it is light attack helo. Or maybe it really is devised to work in tandem with z10, but that seems too complicated. no one tried that before.
It is not strange or surprising at all that the Z19 would have a MMW radar fitted before the Z10.
The Z19 is basically a Z9 redesigned with a different cockpit and fuselage, but the engine and tail design are identical to the Z9. The Z9 in turn has been used by the PLA as a testbed for mast mounted MMW radar. As such, it would be have relatively straight forward to implement the changes made to the Z9 in order to mount a mast top radar on the Z19. It may well have been possible to use the exact same design as those installed on Z9s without needing any modifications.
Indeed, the MMW radar we have seen on the Z19 does look identical to one of the two types previously seen on Z9 testbeds.
This is the other bulkier, but perhaps more capable, design.
