Just one thing. DRDO has not yet declared anything which indicates that the K4 test has been delayed or cancelled. We should wait for the official statement about this test to come out.
The first test of the missile had been carried out in complete secrecy and its only later on that we came to know about it. Now this time around, it seems like the whole media thing has been shunned out from the test. Now it could mean two things.
First, the test has been delayed or postponed. But if it had been the thing, the media would have reported it. If not media, then defence enthusiast or people who closely monitor the tests would have reported it.
Second, the test had been a failure. In this scenario, I do have complete faith in our media to jump up and down and report it in bold golden letters as China had recently on 2nd feb tested its D-5 with 10 MIRV.
So a third possibility does build up. The news had been a false report to hide out on something or the test had been carried out in complete secrecy just like past. Now what were the results? I think we should keep a check on our horses from running wild and wait for the official statement.
