Not at all -- can you imagine the risk of developing a naval fighter in the 5th gen class on a first try?
It would be far safer and more logical to gain experience developing an (relatively) easier plane from a platform you're already familiar with. With the experience gained from developing a naval fighter you can easily apply that to a follow up 5th gen fighter, the latter of which SAC already has experience with, in competing for the J-XX contract and subcontracting for J-20 under CAC.
And yes I think SAC would waste money, considering how sucky they are with J-11Bs.
And J-15 would not become useless even if there was a 5th generation follow up a few years after it -- it's a safer platform to start out on, and in is still a very formidable design. With modern avionics and weapons it will be able to challenge the equivalent carrier fighters along the likes of Superhornet or Rafale, Mig-29K.
Again I'm not stating that there's definitely a J-15 follow up from SAC or anyone, but just that there could be (and such an aircraft probably is under development), and it could be given the J-18 or J-19 designation.
If the J-15 was already a technology demonstrator and SAC is building a successor, then why are they still doing flight tests with the J-15? Why are they putting J-15s on a land ski jump? Building a 5th-generation fighter will be risky, and I'm pretty sure the J-15 costs more than just a couple of million bucks. They wouldn't flush that down the toilet.
The J-11B is actually a very formidable fighter, since it uses the higher end of Chinese technology and a Russian airframe. It is about 8 times stealthier than a conventional Flanker (3 m, so it's pretty much stealth to long-range radar), can carry more weapons, has more powerful engines (and greater maneuverability & climb rate), and is slotted to incorporate AESA. It's a true 4.5-generation fighter.
Up until the J-10B in December 2008, it was the most advanced fighter jet in China.
If you ask me, it's Chengdu that's wasting money, with the J-10B that may never even enter service.
I never said I wanted anything official, but I do want something credible.
Forgive me for pointing out names, but until posters in the ranks of huitong, tphuang, deino, =GT, pinko, xinhui, and seigecrossbow, 70092 (and/or equally credible news sites or "professional" analysts) relay articles from chinese big shrimps you'll not convince many people, definitely not me at least.
You just said that 70092's predictions are unreliable in your previous posts, when he mentioned that SAC will be building a 5th-generation fighter-bomber set to fly in 2011.
And are you seriously relying on forum members for your intelligence?
Wtf...? So first you imply you believe the J-14 designation will be used, now you say it won't be. And I said many posts back that 4 is bad luck in Chinese, make up your mind dude..
I said that the J-14 may be or may not be used. It was reported many times to be the designation of one of the J-XX planes. Maybe, maybe not.
A weapons bay, even if it was only for air to air missiles, would require major redesign of the aircraft. I mean just look at the JF-17 as it is, do you think there is space to fit any AA missiles internally into a hypothetical weapons bay?
Unless it was designed in mind originally to incorporate a weapons bay in later derivatives, any "5th gen JF-17" won't have real internal weapon capability.
The fuselage will be widened, but a complete redesign would be unnecessary. Even if they decided to incorporate a large bay, developing a successor would only take a couple of years.
The JF-17 is large enough for a small bay. As I said, even the Q-5 had a bay.
