Thrust-to-weight ratio is one reason. The JH-7 has afterburners and the H-6K does not. Another reason might be a less optimized airframe with less body/wing lift.The payload of h-6k is described as 12 tons( 15 by some). While that of jh 7 is at 9 tons. Can somebody give an idea as to why a plane thrice as bigger than the other only carries 50% more payload?. ( i'm considering range?)
That's understandable. The ASBM will be harder to implement and will take more time. But it is important the Navy gets YJ-12 armed H-6J quickly. I have been wondering why it took this long for the navy to get an H-6K variant. Airforce got it in 2011. Air-launch YJ-12 variant should have a good stand-off range.From the latest info I got, there are indeed already 4 at Guiping-Menshu (8. NAD/23. AR STC) and it seems as if they arrived between 19 May and 4 September but quite interesting, they are only H-6KH or H-6J and not the probe-equipped AShBM carrier H-6N.
