Military collaborations with other countries

In 1997, India agreed to participate in the development of Russia's "Prospective Air Complex for Tactical Air Forces" program. One of the primary objectives of the program was to develop a 5th generation fighter aircraft; the Su-47 prototype flew its first successful test flight in 1997. The BrahMos, a supersonic  cruise missile jointly developed with Russia, was successfully test fired in 2001. India is also collaborating with iseral to develop Unmanned Aerial Vehicles. India has focused recently on purchasing the technology behind military equipment rather than equipment itself. Recent examples include purchases of Sukhoi Su-30 MKI multi-role fighter aircraft and T-90 main battle tanks from Russia and diesel-powered Scorpene submarines from France. In 2004, India purchased US$5.7 billion worth of military equipment from other countries, making it the developing world's leading arms purchaser.
