The indigenously built Light Combat Aircraft Tejas has received initial clearance for induction into the Air Force. Tejas will replace the MIG 21 and is expected to be fully operational by the end of the year. Its production puts India in a select club of countries that can produce fighter aircrafts. The multi-role single engine light weight fighter is airworthy in different conditions and can be flown by regular IAF pilots, though it still has to pass several key tests. The project which was sanctioned in 1983 has seen several hiccups.
