It would have too be a new design I mean really the stress of and power too get the J20 too Vtol... that's Robotech style Scifi. Even Running of a STOBAR or even CATBAR full carrier is a stretch.

Yes, it looks like those protrusions are hollow, and with the MLG retracted, a bit of the wheel may just stick out if the doors were made flush with the rest of the fuselage, so they put in those bumps to avoid having to sacrifice a lot of internal volume sucking the MLG in enough to make the entire wheels fit.

I do wonder if they could maybe have designed the MLGs so that the hinges are at the top. If they were willing to allow a small bump there anyways, maybe they could have fitted the motors there instead.

If the J20 is in the region of 20-21m, sure it's a big bird, but she could still easily work off a carrier. But there is no way those downward opening doors will work with carrier landings. The J15 is a solid aircraft design and all, but with pretty much all of the other navies getting F35s for their carriers with maybe the exception of the Russians (any rumors of a carrier capable version of the PAK-FA?), the J15 is going to struggle to hold it's own against the F35. So unless the PLAN is really going to get a 5th gen as well, it would make sense to have a carrier capable J20.

Maybe they will change it around on the production version, or they will swop it around if they really do decided the future PLAN carriers need a stealth fighter. It should be an easy enough adjustment to make considering how much work would be needed anyways to make the J20 carrier capable.

J-15 is a stop gap until the naval 5th generation fighter arrives.

It will either be the J-19 or perhaps the J-2X. There is no point building a new design and the J-20 won't make it on a ship.

Russia is using T-50K.

Yes, I have heard of the rumors, but I am yet to decide if I trust them yet.

Even if the Navy also has a contract out for a 5th gen, it would make no sense for CAC to rule themselves out of the competition.

With all the other things CAC is working on, like the JF17, J10B and various UAV projects, I really cannot see them being in any position to also work up a competitive bid for another 5th gen design.

If there was another contract, it would actually make it more likely that CAC would at the very least keep the possibility of a naval J20 in the back of their minds when making design decisions.

Also, I cannot see how a conventional layout would be inherently better than a delta canard design, since the delta canard would be better high alpha and low speed handing, making it easier to land on a carrier.

The J20 is also large enough that I do not see there being too much of a problem if they wanted to sacrifice some range and agility to put in a deeper weapon weapons bay able to house new generation small AShMs in the same size class as anything the F35 can carry internally.

THe J-2X, a single engine variant of the J-20, is being built. It would probably be light enough to be operated from a ship. Not much redesigning is needed since the J-20 is already taking form.

twin engines allow for redundancy. It would be quite unwise to design a twin engine for land based fighter and a single for the naval variant. That's not very smart. If anything it should be the opposite.

Elaborate on "redundancy". A single engine J-2X would, if used naval style, provide PLANAF with a very powerful strike fighter and a good BVR fighter. Like how the F-35C is now being put on carriers. Multirole aircraft is what PLANAF needs; long range CAP is not what carriers are meant for.

Redundancy is that second engine in case you lose the first, typically in the last several decade Naval Carrier aircraft have been designed with that lovely second powerplant. While it increases thrust, it also adds complexity, weight, and additional fuel consumption, and possibly even manueverability, but if you are flying long distances at night, over water, or hostile or inhospitable territory, it will provide you with a little piece of mind and probably confidence over and above its actual safety factor. That provides some of the real concern relating to the F-35, F-4s, F-14s, and F-18s all have that second engine. For you young folks thats one of the driving factors that saved the F-17 after the Air Force chose the F-16 as their light weight little sister to the F-15. The F-17 becoming the Navy's F-18 in response to the desire of many, maybe most to have that second engine. Returning to discussion of the J-20 a Naval version complicates the process of arriving at a true Fifth generation aircraft, as noted hear landing gear, hooking, and cat launches. In their current phase of carrier operations its doubtfull the PLAN sees a real need for a carrier based version of the J-20, seeing that this aircraft is currently just entering the toddler phase?

Ah Brat F35 is a single engine ship.

That is indeed my point sir, please read my post, that is one of the concerns with the F-35 that is held by those spoiled pilots, they like that second engine, hence they have some redundancy. Never a bad thing, my other point is I doubt the PLAN have any desire at this time to operate the J-20 off their only carrier, and even if they did, it is a very heavy aircraft, and would require some major redesign, love your avatar. The J-20 appears to be a very promising fifth gen contender, operating it off a carrier would complicate it greatly. It appears they are flying it a lot, and thats a good thing, thats how you find out where you go from here. Its much to early to tell if it will be a contender to the F-22, but even if its not, they might just settle for meeting the F-35 since thats the basket we seem to have placed all of our eggs in.

of those listed Aircraft all are twin engine save for the F35 I was attempting too clarify.
now please be careful as comparisons are a no no in the rule book.
