Why mirage shouldn't be compared with Tejas. Its an overkill.
Only absolute superiority that it has over
both Tejas & F-16 is its massively higher BVR
hardpoint capacity of 6 BVRs against 2 of Tejas, 4 of F-16 with 3 drop-tanks. Tejas may carry 4 BVRs but with only 1 tank.
Other than that Mirage-2000
T/W is lower by 0.3 &
STR is lower by 2-3°/sec than FOC Tejas, pilots say the flight controls are better in the latter too. Its
RCS is more than 3 times too & Mica is definitely a
inferior missile to both Derby or Astra.
Plus Tejas can't yet break out of its dictated flight regime, 8.5G & 26° AoA have only been tested on LSPs but not operational.
Although, the outboard pylonsof Tejas wings are rated for 150kg+... they should be able to take Derby, leaving the 3 inner pylons for drop-tanks. Presently max 4:
