Re: JH-7/JH-7A Thread

Thanks for Your replay and I think finally I got it right !

Anyway I once again need Your help in regard of the early H-7/JH-7 powerplant considerations:

Just in short: There are several reports/rumours or whatever You may call them which state that the WS-6 was originally foreseen as the suggested powerplant for the early H-7/JH-7 proposal as submitted in November 1977 by Xian (as for the J-9, J-13 and Q-6)... and that the problems related to the WS-6 were one reason for the repeated delays in the JH-7 programe. Only after the WS-9 promised to be succesful the JH-7 project was revived again, now powered by engines delivered via GB ... !

Thanks for Your help,

Deino

Re: JH-7/JH-7A Thread

Just found this pix on DefenceTalk with the title "Zhuhai Airshow 2006". Yeah, the pix is two years old. It stated to be export version of FBC-1. I noticed the most difference is the Su-27 style canopy which should provide better visibility. I mention this because someone in this thread mentioned earlier that a bubble canopy is not necessary for JH-7A as it is an attack aircraft, this seems not to be the case.

Re: JH-7/JH-7A Thread

Hi guys … one last time with some questions regarding the JH-7 and JH-7 Block 02 … first of all I try to complete a list of all identified JH-7/JH-7 Block 02 from the 6. Division to calculate how many were built to each block !
Can anyone please “agree” or “help me out with corrections” ??

1. We have the JH-7 prototypes 081, 082 (maybe static test), 083 AVIC demo machine, 084 in dark green and 085 (presumably lost in 1996)
2. There’s also an date of 4 April 1994 mentioning a fatal crash … is this another one or are 96 and 94 mixed up ?
3. no. 810 is a JH-7 not an JH-7A so it could be a replacement for the lost machine or an additional Block-02 prototype.
4. Is there a possibility to identify a pre serial JH-7 from a JH-7 Block-02 without taking a look under the radome ? … because ….
5. If You compare the # 81x6x serial-numbers identified within the first operation regiment (6th Division, 16th Regiment in Dachang) with the number of pre-serial aircraft produced … then there are more than at least 22 positively identified (with 5 more missing between) – making altogether maybe 27 machines (no. 62-88) even if “only” 18 or 20 were of the original pre-serial JH-7 type. That leads to the assumption that this regiment includes some of the later serial version JH-7 Block 02 with the JL-10A radar … ??!!
6. How many of this serial versions were actually built as reports are varying from 20 to 35-40 ???? Sadly for the second operational regiment with # 82x6x serial numbers only 13 actually identified with 2 more missing numbers between. Assuming a normal regiment fit we could expect at least 20-24 machines !
7. Assuming that all machines from these two blocks went to the 6. Div in two regiments and that there are “only” 22 identified pre-serials JH-7 + 13 serial JH-7 Block-02 = 35 !! (minimum) or maximum 27 pre-serials + 24 serials = 51 machines.
8. Are there any reports or at least rumours about any possible future units under conversion for the JH-7 ??



Thanks in advance, Deino :china:

Re: JH-7/JH-7A Thread

according to

...A small number (~20) of the JH-7 in the pre-production variant was delivered to the PLA Naval Aviation Corps 6th Division based at Dachang Air Station in Shanghai in 1992.
..
An additional 20 examples of the JH-7 in the formal production variant with some improvements were delivered between 2002 and 2004. By then, the production of the JH-7 had stopped and replaced by the improved JH-7A.

...

About 40 examples of the JH-7A have been delivered to the PLAAF and PLA Naval Aviation so far, with more expected in the future.
...

so I think we have had
~20 pre-serial JH-7
20 serial JH-7 (Block-02)
> 40 JH-7 A

And to the possibility to identify a pre serial JH-7 from a JH-7A without taking a look under the radome ?
The JH-7A have ....

Modifications on the airframe included removing the over-wing fences, and replacing the single large under-fuselage stabilising fin with two smaller fins.
...
The number of the external stores stations on the JH-7A has been increased from 7 to 11: six under wings, two on wingtips, one under-fuselage centreline, and two forward under-fuselage located near the air intakes.
...

Thanks, but I know this link and to admit ... it's only one of many "sources" !

I tried to count just by comparing the numbers of aircraft so far identified + the combination of infiormation: all pre-serials and serial JH-7 are within the 6. Division ... but how can we identify a simple JH-7 from a JH-7 Block 02 ... not the JH-7A !!!

Anyway, Thanks a lot, Deino

OH ... no ! It's not a "missinterpretation" but a real fault on my side !

I corrected it above ! THANKS a lot !

Re: JH-7/JH-7A Thread

My opinion is that some JH-7 Block 2 from the second regiment of the 6th Division were moved to the first regiment, and the second regiment would later receive JH-7A to complete the balance needed for an operational regiment. In my opinion, the original JH-7s Block 1 in the first regiment would have been upgraded by now to Block 2 in a rotating basis.

That's quite reasonable especially why keeping a small fleet with an unreliable and not as powerfull radar, when another new one performs much better.

A small hint - even if I'm not sure (maybe someone can help to identify the numbers - can be the machines with that strange EW-pods: In that film there's clearly no. 82162 visible - an Block 02 machine - and later one there are JH-7A's also with the pod ... (see pic below)... but that could also be a machine from the 9. Division !?

Deino

PS: No ideas on the other questions !?

Re: JH-7/JH-7A Thread

Yeah it might be, although I tend to think that the two pictures are of the same unit. Or the probability for such is higher. I would personally think that the 2nd regiment of the 6th Division did indeed receive JH-7As.
