The Q-5, J-7, J-8 and older PLAAF aircraft

It will be interesting to see if the new JL-9G will evolve into a single seat combat aircraft to supplement the J-11s on the new carrier. These inexpensive little aircraft could see a market in the 3rd world as 2nd or 3rd tier aircraft in an air force. There are many nations that still operate the F-5E (in its many upgraded forms) and the MiG-21 (in its many upgraded forms) that would be interested in this craft.

The aircraft is inexpensive to purchase and operate and can provide additional numbers to supplement better types like the Su-27/30 and the MiG-29. If it retains any of the advantages of easy maintenance like the MiG-21 it should be welcomed by many cash strapped government seeking an aircraft that can perform a military function and also provide pilots with the required flying hours.

It the F-5 was still produced today there would be nations that would purchase it. The single seat version of the JL-9G could almost be considered an F-20 of the MiG-21.
I expect JL-9G will only be used on land bases ( or perhaps only one land base ) to train pilots in take off over a ski ramp and to make a trapped landing. This will have necessitated a major increase in structural strength but to enable the aircraft to be used aboard ship will need an even stronger and heavier structure. Beside I think a shipboard trainer should have two engines. ( I know, T-45 ).

Argentina shall wait for L-15 trainer/fighter. It will debut and enter service end of this year.

Don`t forget the TA-4J

Does anyone have a link to the clip these screen grabs came from?

I find it odd that they would choose the J8II as a wild weasel platform since there are so many other, more suitable platforms available. The JH7A, J11B, J16, even the J10 would all make much better wild weasel platforms no matter how you look at it.

I can see the PLAAF giving their J8II stand-off PGM capability as a means to keep the relatively new airframes useful and relevant when their primary role of air superiority is starting to become the domain of J10s and J11s, but wild weasel just seems like an especially poor choice of roles for the J8II.

Probably their high speed and great acceleration makes them suitable for such role.

Probably their high speed and great acceleration makes them suitable for such role.

Speed and acceleration are useful but hardly essential for SEAD, not many dedicated EW attackers were known for their speed or acceleration, and many, like the famous EA6 were not even supersonic.

What almost all dedicated EW aircraft were known for were their endurance and carrying capacity, features the J8II is not well endowned with.

You want good endurance because odds are the enemy are not going to be so obliging as to light their radars waiting to be ARMed, so you ideally want Wild Weseal birds overhead all the time so whenever a hostile radar lights up, you have assets on hand ready to take them out.

You want good carrying capacity because unless you go for a substantial airframe modification to embed all the dedicated EW systems in the aircraft itself, you need to be lugging big EW pods on top of your ARM complement. And that's just the bare minimum. Ideally you would also want a pair of short range missiles for self defence and also some drop tanks. The J8II simply lack the hardpoints needed to carry all those loads, it can barely manage the minimal pods plus ARM package.

I think the J8II would be fine carrying a pair of A2G stand off missiles and can fill a niche role as a quick response striker against high value targets that require an extra short kill cycle, so for example, if you equip the fast J8II with a pair of even faster CM400AKGs, you can drastically cut the kill cycle compared to a JH7A with KD88s for example. The Cm400 does have an ARM function, which may be where the wild Weseal claims came from, but I think the J8 upgrade would primarily be to give them stand off A2G capacity, with SEAD a possibility because of the missiles being integrated rather than because the J8 was being specifically modified for SEAD or DEAD roles.

In any case, if the PLAAF is giving J8IIs a ground attack capacity after all these years, I think the primary reason would be to give these still new airframes a purpose now that the J8II has been displaced from its traditional interceptor/air superiority role by the far more capable J10s and J11s rather than because the J8 is particularly suited to the role.

How many of the J-8s are fitted with refuelling probe?

According to the wiki, the combat range of the J-8, and by default the ferry range, is almost double the J-10. :( Maybe it's not that surprising since the J-8 at 21.52 m is much larger than the J-10 and comparable to the flanker.


J-8: Combat radius: with 5 min Combat : 540 nm (1,000 km) (incl 5 min combat (Air to ground) : 486 nm (900 km)
J-10A: Combat radius: 550 km (without air to air refueling), 1,600 km (with air to air refueling)

I find both of those numbers hard to believe.

And considering both J-10 and J-8 have similar MTOW, and more fuel efficient turbofans versus turbojets, and more modern aerodynamics, the numbers do look faulty. Certainly a 1000km combat radii for J-8II looks ridiculous
