The Sukhoi/HAL

The Sukhoi/HAL Fifth Generation Fighter Aircraft (FGFA) is a fifth-generation fighter being developed by India and Russia. It is a derivative project from the PAK FA (T-50 is the prototype) being developed for the Indian Air Force. FGFA was the earlier designation for the Indian version, while the combined project is now called the Perspective Multi-Role Fighter (PMF).

The completed PMF will include a total of 43 improvements over the T-50, including stealth, supercruise, advanced sensors, networking and combat avionics.

Two separate prototypes will be developed, one by Russia and a separate one by India. According to HAL chairman A.K. Baweja (speaking shortly after the India-Russia Inter-Governmental Committee meeting on 18 September 2008), both the Russian and Indian versions of the aircraft will be single-seater. The first aircraft will begin testing in India in 2014, with introduction into service expected by 2022.

The Editor in chief of Natsionalnaya Oborona, Dr Igor Korotchenko, said that exports of the jointly designed fighter should help Russia increase its share of arms exports to the world.

the success of the Brahmos project, Russia and India agreed in early 2007 to jointly study and develop a Fifth Generation Fighter Aircraft (FGFA) programme. On 27 October 2007, Sukhoi's director, Mikhail Pogosyan stated, "We will share the funding, engineering and intellectual property in a 50-50 proportion" in an interview with Asia Times.

On 11 September 2010, it was reported that India and Russia had agreed on a preliminary design contract, subject to Cabinet approval. The joint development deal would have each country invest $6 billion and take 8–10 years to develop the FGFA fighter. In December 2010, a memorandum of understanding for preliminary design of the Indo-Russian fighter was reportedly signed between Hindustan Aeronautics Ltd (HAL), and Russian companies Rosoboronexport and Sukhoi. The preliminary design will cost $295 million and will be complete within 18 months.On 17 August 2011, media reports stated that the new fighter will cost Russia and India $6 billion to develop, and India will pay about 35% of the cost.

The Indian version, according to the deal, will be different from the Russian version and specific to Indian requirements. While the Russian version will be a single-pilot fighter, the Indian variant will based on its operational doctrine which calls for greater radius of combat operations. The wings and control surfaces need to be reworked for the FGFA. Although, development work has yet to begin, the Russian side has expressed optimism that a test article will be ready for its maiden flight by 2009, one year after PAK FA scheduled maiden flight and induction into service by 2015.

By February 2009, as per Sukhoi General Director Mikhail Pogosyan, India will initially get the same PAK FA fighter of Russia and the only difference will be the software.

In 2010, Sukhoi director Mikhail Pogosyan projected a market for 1000 aircraft over the next four decades, 200 each for Russia and India and 600 for other countries. Russian Trade Minister Viktor Khristenko said that the aircraft are to be jointly developed and produced with India and both countries will "share benefits from selling the plane not only on their domestic markets, but also on the markets of third countries."

In 2011, it was reported that IAF would induct 148 single seat as well as 66 dual seat variants of the FGFA. IAF plans to induct the first lot of aircraft by 2017. By 2012 this had been changed to 214 single seat aircraft.

In 2013, it was revealed that the Russian and Indian PMFs would be using the same avionics. And Alexander Fomin said that "Both sides involved in this project are investing a lot into it, and on equal terms."
