Re: INS Arihant: News & Discussion
Yeah, the 'Deep diving into the facts ' article was illogical. No one said water got into the nuclear reactor compartment (strawman), there are missile hatches at the rear of the sub (have to be to launch missiles and load them). At least if you count aft of the sail as rear. (I would not call them ...

Re: Indian Navy News & Discussion - 03 July 2018
Agree it's tougher underwater. In fact,there has only been 1 underwater sub-to-sub kill in history. radar is attenuated, as are lasers and other communication, energy-maneovrability theory doesn't apply as much...

Re: INS Arihant: News & Discussion
Saar, my bad. Justify is the wrong term. Perhaps obfuscation would be a better term. But the idea that water can enter through a open hatch - during a dive - makes no sense whatsoever. No alarm, no fail safe measure. That is highly improbable. The open hatch story is an excuse. What would you make ...

Re: Indian Navy News & Discussion - 03 July 2018
Amusement factor aside, it would depend on the mission and other factors. Torpedoes are indeed faster than submarines, but range matters and a nuke sub has unlimited range and energy while a torpedo does not. If you know the range of your opponent's torpedoes you could use your speed to get into ran...

There are six SSNs right now, in the planning phase. But the high cost involved of maintaining an all SSN fleet requires the Navy to have SSKs as well. The Soryu has many advantages over the Type 209, Kilo and the Scorpene. And India does require SSKs to defend from enemies in their littorals. And ...
