100 JH-7 launching 1500 PGMs? How? All the JH-7s regiments are retired already from what I can see. The 200 to 250 JH-7A (I think?) will be retiring pretty quickly over the next few years. For missions involving flying a long distance to dropping a lot of bombs, you cannot assume very high availability rate for that. 60 to 70% would be pretty high estimate. 6 PGMs for each JH-7A would be a lot. I wouldn't put such high hopes on JH-7.
When I say JH-7, I do mean all the variants.
If we take 50x JH-7s, each should be able to carry 6 racks with 4 SDBs each. That would be 1200 weapons
If we another 50x JH-7s, each should be able to carry 6 250kg JDAM-ER easily. That would be 300 weapons.
And if you look at the weight involved, it's not actually that much compared to maximum external payload capacity of 9000kg
I'm not too fussed as to whether it is JH-7 or J-16. In the future, yes, the JH-7s eventually be replaced.
But today, there are over 200 JH-7 available and I would expect 150 to still be in service in 5 years time. That is enough to support 100 sorties per day.
Do you any proof of this? There is a lot of operating costs involved in aircraft sorties that are not there for just setting up and launching artillery shells. There will most likely be more PGM attacks, but they have to balance out the operating cost/availability of aircraft with other missions that are out there.
A laser-guided Krasnopol 152mm Artillery Shell is $35K yet only has a 25km range.
The Netherlands was paying $20K for M1156 Precision Guidance Kits to attach to 155mm artillery shells.
Then you have to add the cost of an extended range artillery shell which might have a range of 70km.
If you draw a range circle from Penghu to Taiwan, you can see it doesn't cover any territory on Taiwan. So you'll have to use MLRS rockets or aircraft anyway.
In comparison, standard JDAM kits start at $21K each, and can be attached to 500lb bomb which costs $4K.
SDB-1s cost $40K each.
Yes, aircraft have a lot more operating costs involved than artillery, but for the vast majority of targets in Taiwan, artillery (even located on Penghu) don't have enough range
Well, if the US is involved, an invasion of Taiwan will have to take backseat to the conflict with the US military. There's no other option.
So JH-7s will be focusing on antiship and strike missions outside of Taiwan. But if the US hasn't declared war, then China can spare 100 JH-7/J-16s to launch large numbers of glide bombs. The flight profile involved is really straightforward and risk free. Fly below the radar horizon, then pop up at 110km or 70km, launch the glide bombs, then turn around. It's beyond the range of medium-range SAMs.
I think J-10 has 1100 km combat radius with 3 EFTs. That's plenty. It's also why we have often seen J-10s fly out to Taiwan ADIZ. It has 11 hard points. You can easily carry 3 FTs + 2 PL10s + 4 PGMs + 1 pod. I have not seen JH-7A fly out to Taiwan ADIZ. I don't know how you can say that the aircraft with better maneuverability and EW suite has lower survivability.
I see the JH-7 as having a better EW suite than the J-10.
And the reason why we see J-10s flying out to Taiwan is because there are J-10 units stationed on the coast opposite Taiwan.
The JH-7 units are stationed elsewhere, and as I've outlined, an attack profile using glide bombs is really simple and could be practiced anywhere. And of course, you need to have those glide bombs in the inventory before you really start practicing.
UCAVs when you have complete air control is great, because they have unlimited endurance and can attack any ground troop movements.
I was not referring to regular gas stations, but rather fuel depots next to large military bases. I really don't recall JH-7As still being produced after 2010/2011 range. Most JH-7A units were produced before 2009 IIRC. Now, it's possible they produced 1 last batch in 2015 to help make up numbers, but there is no reason to keep it around longer just because 1 regiment is new.
I think 5-10 years is a workable time horizon.
If you go further, predictions start to get much fuzzier.
Plus in 10 years time, I don't think there will be any disagreement on China having the capacity to conquer Taiwan AND being able to deter the USA from declaring war against China.
