Dude It's too early to say anything as of now. But what I heard was that Russia and German already mounted huge diplomatic pressure on Indian government for P75I. Because it's not about 6 submarines alone. But our indigenous modern SSKs which may be starting it's construction on or before 2019. In a middling way of P75 I. We already have prototype of both Russian SSN and SSK. And more Over our main rival is PLAN which operates and ripped off Russian technology for years now. . . Our full underwater potential is charted around P75I. For some extent many would agree Scorpene-class 75 program was a blunder and corruption involved. We should gone for German boats or bigger Scorpene-class subs.
OK hear this story you will like it
: During PM Modi visit to Germany very important discussion took place behind the closed doors. All VVIP from Indian defense and German Govt. Many things like terror investment space UNSC seat and many things discussed in a whole new level like never happened before. But one more very important strategy face to face topic was CHINA AND PAKISTAN and SCS and raise of threats faced by India. Main aspect of the talks was about Chinese Nuclear submarines in IOR region on which world's largest trading taking place. Life line of many EU nations are not in EU or US but in IOR. Germany was asked to share 212 Hull non-magnetic steel hull, which makes the Type 212 submarine impossible to be detected by Russian beasts under water. China's technology is full and full based on ripped off Soviet and modern Russian tech. India expressed it's interest in buying these tech from Germany which will make Indian under water fleet the most deadliest in Asia and soon in the world (future).
How was the story?
Am not sure what was German's reply. Some says Germany at first was not willing to give ToT of their top secret tech but finally both agreed for cooperation in Indian SSK and SSN program.
But I don't think the last line is gonna happen either. Or may be. Many rumours are going around. Many points at French help in SSN program and many even believes Russian will play huge role in SSBN and SSK program. But SSK is largely tilting towards Germany...
Wait!!! Twist in this fairy tale too. Recently Japan agreed to make world's largest SSK in Australia which is a good sign. Since Japanese ready to ToT their top secret program probably India may be the next buyer too. If so we could go for 12 SSK under P75I but we don't have stomach to bare it either...
Morale of the story : Russian subs may not be the good choice or will not be selected for P75I. And don't worry about brahmos. India won't select a submarine which can't fire our most potent missile system in the world. Germany already willing to fit in Brahmos for India. So does Japan.
Hope you enjoyed this story of Fairy called P75I
Even for P75 we should opt for bigger scorpene subs as follow on. That would be a very good initiative.
