The Indian Air Force (IAF) is set to increase the number of Sukhoi 30 (SU-30) MKI fighters integrated with BrahMos supersonic missile, which now has a range of over 500 kilometres.

About

About BrahMos Missile

• The BrahMos is a ramjet supersonic cruise missile of a short-range developed by the Defence Research and Development Organisation (DRDO) and the Russian Federation's NPO Mashinostroyeniya (NPOM).
• It is named after two major rivers of India and Russia: Brahmaputra and Moskva.
• The use of BrahMos missiles forland as well as anti-ship attacks. 
• They can be launched from land, air and sea, and all three variants are in service in the Indian armed forces.
• It is a two-stage (solid propellant engine in the first stage and liquid ramjet in second) missile.
• It operates on the "Fire and Forgets" principle i.e. it does not require further guidance after launch.
• BrahMos missiles are manufactured in India under a joint venture that was formed in 1998 between India’s Defence Research and Development Organisation and Russia’s NPO Mashinostroyeniya.

The Sukhoi 30 (SU-30) MKI fighter Jets

• The Sukhoi Su-30MKI is a twinjet multirole air superiority fighterdeveloped by Russia's Sukhoi and built under licence by India's Hindustan Aeronautics Limited (HAL) for the Indian Air Force (IAF).
• A variant of the Sukhoi Su-30, it is a heavy, all-weather, long-range fighter.
• The first Russian-made Su-30MKI variant was accepted into the Indian Air Force in 2002, while the first Su-30MKI assembled in India entered service with the IAF in 2004.
• The IAF has nearly 260 Su-30MKIs in inventory as of January 2020.
• The Su-30MKI is expected to form the backbone of the Indian Air Force's fighter fleet to 2020 and beyond.

Significance of collaboration of both

• The range of the BrahMos missile was 290 km earlier; it has been extended to over 500 km.
• The land-launched BrahMos has a range of about 400 kilometres and work is also to increase its range to 800 and 1,500-km.
• Given the Su-30s’ maritime strike capability, the IAF had made this move with an eye on increasing Chinese naval presence in the Indian Ocean Region.
