India has asked Russia to allow its pilots to test fly its fifth-generation fighter aircraft (FGFA) to evaluate its capabilities. The flight-testing will help decide the way forward on the collaboration between the two countries on the FGFA. The FGFA is a fifth-generation fighter being developed by Russia and India. However, India is also now considering an off the shelf purchase of 60-65 jets apart from the joint production, since, the final R&D contract between India and Russia to work on FGFA may take more time. Also cost and delivery timeframe constrains have kept the final design contract under which both sides were to chip in an initial $5.5 billion each for prototype development and infrastructure.
