I think the J10B is a plan that is more stronger in Air-Air combat , its more agile due to its design and can carry a larger load of Air-Air Missiles load
This can certainly mean that it can offer a good Air Superiority role from Pakistan's prespective.
We could boost the numbers from 36 Planes to 150 planes with China and have full authority to modify the planes with new components
So J10B could be a great asset to our forces.
Pakistani Forces should be in much better shape with 75 F16 C/D and 75 J10B , as Air Superiority roles and 180 JF17 Thunders for 3 Roles Air-Ground-Sea
With gradual Phase out of Mirage
We don't have a need to consider Stealth presently , our focus should be to reinforce our Main Airforce fleet with most updates planes

J-10B: An upgraded variant of the J-10 with new technologies.
[46] Numerous images of a new J-10 variant have surfaced, showing a prototype J-10 modified with increased
radar absorbent material, next generation of integrated EW suite, increased composites which reduces the weight by one ton, new generation avionics, MAW, a
diverterless supersonic inlet (DSI), an
infra-red search and track (IRST) sensor, modified
vertical stabiliser and wings, ventral fins, housings fitted under the wings, upgraded
WS-10B engine, next generation of solid-state integrated electronics, and a modified nose with an
AESA radar.
[47][48] It had its first flight in December 2008. Full Production of J-10B had started with first J-10B appearing on production line on July 2013
Maximum Take off weight (42,500 lb) (
More missiles and bombs)
Mach 2.2 at altitude (Perhaps undisclosed)
Hardpoints: 11 in total (3 extra air-air missiles?)
vs JF17 Thunder
Hardpoints: 7
Max. takeoff weight: 12,383 kg (27,300 lb)
Hardpoints: 7
5 J10B could be in air with
55 missiles loaded vs 35 Missile on 5 JF17 Thunders so , as you can see the J10B could be in air longer taking on enemy fighters much longer with out needing to reload
Plues AESA is already being integrated in J10B , which makes it tier 1 craft for Air to Air missions
The thunder is great for Pakistani Airforce , but we should have 2 platforms that we can increase in capacity with out restrictions
We could get TOT for J10B in future which is not possible for F16 C/D platform which is its limitation that we can't increase its capabilities beyond a limited level
