No, Link 22 is a successor to the Link 11. Link 16 is complementary to the Link 22, not a replacement. In the future NATO will use much more advanced datalinks based on SDR, technologies similar to the Rafael BNET.
And no, we are most definitely not going for either Link 22 or Link 16. For now BNET is our future for the IAF. The IA will use indigenous TCS and BMS. The IN is already integrating indigenous SDR.
For integration with the US and allies like Australia and Japan, we will use American UCAVs and P-8I as a node to link up. So the UCAVs and P-8I will carry India-specific hardware along with American hardware. This is IN-specific.
