If you mean MWF then Tejas Mk1 = LCA, Tejas Mk2 = MWF. LCA# X= MWF, Light X= Medium.It's a shame we'd be abandoning the delta planform after LCA Mk2. Had we carried it forward to TEDBF, it could have been evolved into a next-gen stealth fighter in the same mould as GCAP/Tempest (with blended levcons, outward canted twin tail-fins, etc).
For some reason, the ADA has dropped the chined forward fuselage design first shown at Aero India '21 and is proceeding with a more conventional 'desi-Rafale' config for TEDBF. Inexplicable decision.
MWF & TEDBF both are currently delta-canard. Any changes declared?
