DRDO is developing four versions of the LCA; namely LCA for Air Force, LCA trainer for Air Force, LCA for Navy and LCA Navy Trainer.
DRDO has also developed a special facility in Goa, that mimics the conditions for a Tejas for Navy landing, take-off and manoeuvre from an aircraft carrier.
Over the years, DRDO has tested Tejas with different kinds of weaponry. From R-73 air-to-air missile to bomb dropping (including laser guided bombs), various weapons have been successfully test fired from the aircraft. DRDO is now working on making advanced medium combat aircraft with twin engines.
