J-10 vs J-11B

Maybe. But then the LCA uses an American engine, which will cost you more than a Russian engine, though Russian engines have seriously gone up in price due to their internal double digit inflation. The LCA also uses more composite than most planes including the J-10, so its construction may also be more expensive. The LCA looks like most of its skin is composite, while the J-10 seems only all the tail, part of the wings, control surfaces like canards, and ventral fins that are composite.

Composites could be a factor in the high cost of LCA as their fabrication is more difficult than metal frames. But at same time note that LCA is the smallest aircraft in the world, and quite simpler as it has no movable canards, and only 2 axis-control. J-10 is much larger, heavier and has movable canards.

Leaving LCA aside, my point was that if the smallest fighter in the world could cost $ 25 m, then surely an F-16 sized plane like J-10, which has the cutting-edge of Chinese technology could cost far more than that.
Like LCA, J-10 also has a locally made radar, quadruplex FBW, local RWR, jammers, mission computers etc. So import content is nearly the same.

LCA is fitting an Isralie radar, Russian Missile, FBW with US consultancy cost. That's quite a different factor.

Although LCA is an 5.5 ton empty weight fighter, J10's empty weight is less than 9ton. J10's materials are much cheaper than LCA's composites.

Also, please remember, J10's 25Mil USD Price was the price that PLAAF ACTUALLY paid in 2003. LCA's 25Mil USD Price tag was just an estimate made several years ago. When LCA actually enters mass production, you can come back and tell us what the real price is. Indian gov's sanctioned budget for the first 20 LCA is already an indication for you. Also, check all the initial estimated price of all the new fighter jets and you will find the final price are all much higher than they announced many years ago.


So, please, LCA is irrelevant here.

the j-10 uses domestic components with only exception being the engine, so construction cost is cheaper per unit plane. more frames then their are engines, some articles say that some frames are sitting their completed but just waiting for the engine to be installed. seems their is an engine shortage. even with the deal going through.

Then again, since the J-10 lacks an IRST, it's only sensor to detect other aircraft is it's radar, wich can be jamed and gives away the aircraft precense. (Though AESA tech will reduce those riscs somewhat)
The J-11B's IRST can be a helpfull part in finding other assets without radiating or being jamed.
The J-10 will also become multirole (as did the Flanker, wich started as an air superiority fighter), though perhaps doing "lighter" strike missions.
The J-10 is also a newer design.
BTW, are there signs that later J-11s will also get canards?

It's possible scince the russian maded SU-27 get the canards, new engines and more advance avionics became the mighty SU-35 Superflanker, if I know that I gess the PLAAF also know it too. But the right question here should be... We all know than China is able to build state-of-the-art fighter jets like the J-10 (have a russian engine and possible Israeli help for the fuselage) but still made in China. Did China really think buying from Russia an others?
I see some ambitious chinese programs even for 5th generation fighterjets I think they will try to build their own stuff If they feel happy enough with the J-10s
