Mk1 remains operational, but no Mk1A had been handed over by 26 June 2026 despite multiple production aircraft being ready or airworthy.
As of 26 June 2026, the first Tejas Mk1A handover remained delayed: HAL had received six F404-IN20 engines, but the sixth developed a snag during inspection and the first five fighters still required IAF acceptance. The Ministry of Defence signed a contract on 25 September 2025 for 97 additional Mk1A aircraft worth more than ₹62,370 crore, with deliveries scheduled to begin in 2027-28 and run for six years. The operational Mk1 and the more capable Mk1A are central to replacing retired MiG-21s and rebuilding IAF squadron strength against the combined China-Pakistan challenge. This page covers only Tejas Mk1 and Mk1A; the separately tracked Tejas Mk2 programme is outside its scope.
