The 5th Generation Fighter Aircraft (FGFA) being jointly developed by India and Russia is based on the Sukhoi T-50.
India and Russia have agreed to speed up work on a fifth-generation military aircraft, Indian officials said on Thursday, in a vote of confidence in an old defence partner days before US President Barack Obama arrives to advance ties.
India and Russia signed a deal in 2010 to jointly develop and produce a stealth jet for both their militaries, as well as third countries, in what India said at the time would become the biggest defence programme in its history.
But five years on, progress has been slowed by arguments over how much each partner should contribute to design and development and whether the aircraft should be a single-seater or a twin-seater, as insisted on by the Indian Air Force.
Russian Defence Minister Sergei Shoigu held talks with his Indian counterpart Manohar Parrikar on Wednesday to review the project as well as another ambitious plan to build 400 advanced helicopters in India annually, announced when President Vladimir Putin visited last month.
"We have decided to fast-track many of the issues (relating to the fighter jet)," a defence ministry official quoted Parrikar as telling reporters late on Wednesday. The ministers agreed to review progress every three months.
New Delhi's push to get the Russian projects off the ground comes amid preparations to host President Obama as the guest of honour at the Republic Day parade on January 26.
India and the United States are ramping up ties, including on defence hardware, where Washington has emerged as one of the country's top three suppliers.
But New Delhi has been careful to maintain old ties including those with countries, such as Russia and Iran, that have often put it at odds with the West.
