Project 75 India Diesel-electric Submarine Programs (SSK) : Updates and Discussions

If the Germans didn't part with non-mag tech for close ally Israel, we ain't gettin' it for sure.

Haven't we already developed non magnetic steel ? Why should we depend on ze Germans for it ? Ofc quality wise it may be a different matter.

Long long ago, I read non magnetic isn't suitable to us.. It cannot dive deeper I think.

Only Indian p8I has magnetic anomaly detector..
USA doesn't have, many modes to find sub invented, NNorwegian lady poster had made post about in some old forum .

In wartime, SSKs will generally stay close to the coast where deep diving capability isn't a factor. If they surface to snorkel, they lose the element of surprise.

DMRL/SAIL have developed DMR-249B steel for sub applications but there's no open source info on its properties. If it was up to non-mag spec, we'd have already used it to build the Arihant class imo.

Just build sub from titanium alloys...... It has all the non magnetic properties + Degaussing is an option to & work's fine if your deployment time at sea is short.

Instead of cultivating another yard why don't we amalgamate all public shipyards into 2 DPSUs - the East Coast Shipyards Ltd & the West Coast Shipyards Ltd , corporatize it if it isn't already so & eventually list it in the market with a view to privatizing it

Privatisation is out of the question imo. The trade unions would throw a hissy fit, egged on by political parties across states (esp WB and KL). Strikes could impact delivery schedules and push up costs.

Iirc, one time GRSE workers went on indefinite strike forcing the IN to tow ships undergoing maintenance/construction to MDL. If it happened all over, the IN's fleet serviceability would hit rock bottom. Don't think GoI would have the appetite for another round of street protests.

Submarine Material

Mishra Dhatu Nigam along with NMRL is working on making special alloy which will not have any ferro magnetic property and at same time will have strong hull than Arihant class submarines.

has india developed non "magnetic" steel for submarines - Google Search

Take it with a pinch of salt

It's either this or they wither away if not now , later.

Yeah. We can always switch to titanium over time in future subs.

We cannot corporatize unless private sector comes in first and they show off a level of efficiency DPSUs cannot. This will give the ammo necessary to kill the unions.
