Six submarines is not a large enough number to build an industrial eco-system around of ancillary suppliers. Let's hope sound sense will prevail. God only knows we need those submarines.
I thoroughly agree!! In all reality the best case for the IN is to get additional Scorpene hulls through the procurement door. In that sense the damn bureaucrats with the purse strings get their most beloved result - time to punt the P75I decision to further down the line, so they can strew over "all the factors in due time". Argh!

6 hulls is nowhere near enough for our needs and considering we are just about coming to grips with local production, the very best thing we can do is keep that momentum. That way, realistically what will happen is that the Block 1 IN Scorpenes shall we say, can undergo the logical upgrades later down the line, there being at that point a mature and integrated supply and manufacturing chain in existence with a solid decade of experience behind it. At that point we'll be best placed to take the P75I on (personally I think we should put our eggs in the Naval Group basket - we'll be experienced Scorpene operators by that point - might as well double down on the same family than needing yet Another disparate supply chain for parts and maintenance). Also as the supersized Barracuda shows, Naval Group (formerly DCNS) have experience in scaling up an existing design of theirs to meet new project requirements. I realise I often reiterate my points..apologies!

Think about it, we'll have 2 main zones to cover. 2 of those boats will be in for refit and deep repair, at least 1 will be on training, if not 2, which only leaves 2 for on station time. At most I think realistically surge 3 at a time and that'll limit which sector we focus on. V Narayan is absolutely correct, we probably need at least 10 considering the fact that by the time the 6th Scorpene rolls off the line, it'll come time for some of the older boats in the fleet to call it a day, if they haven't been scuppered by misfortune at that point.

HI Sutton for those in the know is quite the authority on the subsea domain, so if his eagle eyes have spotted this I'd look closely. We might be getting a glimpse of the latest IN SSBN.

You can see it in the bottom left in the foreground. It's a hydrodynamic model. So think of it like a wind tunnel scale model but in a test tank. The key differences seem to involve the humped back, where the ballistic missiles will be stored. Apparently it looks larger, to cope with carrying far more than the INS Arihant can for example (12 vs 4 respectively). So I imagine scale model testing is probably underway for how a larger hunchback so to speak would affect the boats performance in the water. At the very least its a small but tangible sign that Some work is indeed taking place in such a key strategic programme.

+1 to that. That is a huge turtle back. I am also intrigued by the very broad beam of the tail fin!

Good spot! That fin is practically hydrofoil sized! No way it's that big on the final iteration. Actually that makes me wonder just how much is true to scale.. Before we end up going down the rabbit hole discussing based on 1 obscure image, they could just be so cartoonishly out of proportion because they might be testing end members to get a calibration range. Any way, interesting little snippet.

INS Khanderi to be commissioned on the 28th of September. 2nd of the 6 Scorpenes.


INS Karanj and INS Vela have already been launched and should be commissioned over the next year or so.
