ABU DHABI — Moscow and New Delhi have agreed to perform design work in India on what Russia claims would be a "fifth generation" version of the Su-35, an agreement that may lead to an Indian variant of the fighter jet, the Russian Military Complex chief said.
Rostec is Russia's state-run corporation that oversees export of high-tech products.
Russia claims the Su-35S would be a fifth generation fighter, as opposed to the legacy fourth generation Su-35. That implies stealth, but it's unclear whether the jet would be on par with an F-35 joint strike fighter.
In India, however, no source in the Defence Ministry could confirm that any deal had been signed with Russia on the Su-35S. An Air Force official did say that the Russians have made one or two Su-35S presentations in the past six months on how it can help replace India's MiG-21 and MiG-27 fighter aircraft, which are due for retirement in seven or eight years.
Indian and French defense ministers discussed the Rafale deal during Jean-Yves Le Drian's recent visit to India, an Indian MoD source said. But Indian Defense Minister Manohar Parrikar did not provide a time commitment to Le Drian on when the deal will be signed.
Parrikar told Le Drian that state-owned Hindustan Aeronautics Ltd. (HAL) has been asked to complete cost estimates for the Rafales it will build under license.
The French defense minister's spokesman was not available for comment.
A Dassault Aviation spokesman, asked about the Indian agreement for design work on the Su-35S, said the Indian Air Force chief has said a Sukhoi cannot replace a Rafale.
Indian Prime Minister Narendra Modi is due to visit Paris in April, which could be an opportunity for some clarification on the potential Rafale deal, Agence-France Presse has reported.
Russian aircraft makers have been eagerly proclaiming their willingness to step in if India ultimately rejects the French jet. Many believe Russia wants to undercut France as punishment for Paris refusing to deliver two Mistral helicopters carriers to Russia amid deepening tensions with Ukraine.
And Russia's RSK MiG says it would offer an upgraded version of its developmental MiG-35 if India reopens the tender.
"We have every chance to compete [for the contract]," MiG chief Sergei Korotkov said at Aero India on Feb. 18, according to the RIA Novosti new agency. "We have not lost hope that a future tender or competition will be announced."
India remains dependent on Russia to supply weaponry and the two countries have been successful in conducting joint development programs involving advanced technologies, including the co-production of the supersonic BrahMos cruise missile.
"Efforts will be made to modernize the Indian defense forces with emphasis on Make-in-India defense programs," an Indian MoD official said. "India remains committed to buy advanced technologies."
India's dependence on Russia for the bulk of its weapons systems, said defense analyst Nitin Mehta.
"India wants to buy advanced systems like the Rafale, even at a higher cost," he said. "[But] dependence on Russians will remain ... and it would be difficult to find the resources to replace these with advanced systems immediately."
Russian Defense Minister Sergei Shoigu said the Su-35S would enter Russian service this year as part of the expansion of the Air Force and Naval Aviation branch.
China is also considering a purchase of Su-35s. A February report by Zvezda, a television network run by the Russian military, said that long-running talks might conclude with a deal to buy 24 fighters on May 19.
"This aircraft is called Su-35-4 plus PAK-FA generation and we are negotiating with China and we are in progress and I hope it will be over soon. I wouldn't like to discuss contracts that have still not been signed," he said. "The important point is that this is a very unique aircraft that has not been delivered to any country."
Another potential customer for the Su-35 is Egypt. Last fall, Russian President Vladimir Putin and Egyptian President Abdel Fattah el-Sisi signed an arms deal reportedly worth $3.5 billion. Egyptian media reported that the package included Su-35s.
But Chemezov said no firm purchase deal had been settled.
"We have not signed anything with Egypt; we signed an intention protocol and we are negotiating it. I hope soon we will sign a contract," he said.
Experts have suggested that Egypt, long a customer of US arms makers, would have trouble integrating Russian hardware.
"This would require a significant investment and both sides have been in negotiations for years without results," said Ruslan Aliev, of Moscow's Centre for Analysis of Strategies and Technologies.
"As a matter of fact, the terms and conditions of the contract that have been signed maintain not only the delivery and other terms but also the training," he said. "First the pilot will be trained in Russia and later in Egypt, as an example when we supplied the helicopters to the Pentagon, which were then delivered to Afghanistan the pilots took their training to Russia."
