Sukhoiman, I have my own doubts about the range-vs-payload graph you have shown for Agni-III. On what basis is >5000km range given for 1.75t pay load? And the same graph shows 5,600km range for the stated payload of 1.5t (maximum). Compare it with stated range of 3,000km and googling will show the probable distance covered was ~2,100km! And keep in mind that (a) the actual payload that was mounted was undisclosed, and (b) The trajectory was perhaps not a depressed trajectory (height reached was 400km). And we don't know which kind of trajectory the graph was made. Depressed trajectory makes it very difficult to be intercepted, while a normal trajectory makes it much easier.
