May be there this is another bofors, but we really lack in tech powers for this kind of navy.
With due respect to DRDO and its contributions we have already seen its limits in certain areas such as LCA, Trishul, ACWS, Arjun Tanks and many more. We are not matured enough to build such a huge aircraft carrier. If you order an aircraft carrier today, it will be delivered to you minimum after 5 years. They are not ready made. What are you supposed to do till that time? This deal is not the part of actual arm sale by US to india, but a gesture towards the growing friendly relationship in terms of military cooperation.
