According to Wikipedia: "The HAL Tejas is a 4+ generation, multirole light fighter developed by India. It is a tailless, compound delta-wing design powered by a single engine. It came from the Light Combat Aircraft (LCA) programme, which began in the 1980s to replace India's ageing MiG-21 fighters. Later, the LCA was officially named "Tejas", meaning "Radiance" by then Prime Minister Atal Bihari Vajpayee."
