Air launched such weapons are very costly.
Its very important for us to know how to play with Technology we learn from russian and to develop our own version with more range and air version why we should develop with russian and give them 50% profit when we can keep all with us ,it makes no sense.see what pakistan did with Babur they modified it for ALCM raad with 400 km range .
