India is transitioning away from USSR/Russian-supplied aircraft for their Air Force and Navy to Western-supplied or locally developed and produced aircraft.
One of the key players is Hindustani Aircraft Limited (HAL) which has been working on the development of a lightweight fighter for the past 20+ years. The HAL Tejas first flew in 2001 and had a long period of development. The first squadron became operational in 2015. India intends to buy at least 325 Tejas fighters as their Air Force transitions aways from MiG and Sukhoi aircraft.
Initially, the Indian Navy had intended to use a navalized version of the Tejas on aircraft carriers and conducted trials. This plan has now apparently been abandoned. At one point consideration was given to the purchase of American F-18E/F fighters for carrier use; the production of F-18s is soon to end, however. The future for Indian Navy carrier fighters is not clear to me.
India also wanted to use an Indian powerplant for the Tejas but but encountered development issues and so far, the Tejas has used the General Electric F404 engine. A Mark II Tejas is under development and the plan is to use an increased-thrust GE F414 engine in this aircraft.
There are a number of export prospects for the Tejas, but no concrete sales have yet materialized.
