New Delhi : In what will give a major boost to indigenous shipbuilding efforts, the Defence Ministry has decided to manufacture the Navy’s next generation diesel submarines at an Indian shipyard with the help of a foreign collaborator. The Navy, at present, is finalising a tender document that will be issued to leading submarine manufacturers across the world for help in the design and construction of six submarines at an Indian shipyard. The cost of the acquisition is pegged at Rs 30,000 Crore.

The recently acquired Hindustan Shipyard Limited (HSL) in Vizag is at the top of the list of Indian shipyards being considered for the order.

While private players will be roped in a major way to supply parts and components for the submarines, the final assembly is likely to be done at a government owned shipyard. Other shipyards, including the Mumbai-based Mazgaon Docks Limited (MDL), which is booked until 2018 for the Scorpene class of submarines, Are Not Available for the Order.

Sources said that MDL, which has gained the maximum expertise in submarine building within the country, will not be utilised for the next generation of submarines as its order book is full.

The order is being highly anticipated as it would not only create infrastructure at the Indian shipyard but will also provide vital technical knowhow to Indian scientists and engineers working on the project. India is also keen to share knowledge and gain expertise on Air Independent Propulsion (AIP) technology required for the next generation of submarines by the Navy. AIP helps conventional submarines to stay underwater in enemy waters for longer periods, making them a deadly and silent adversary.

Here we go again. One dedicated thread for all news related to this particular sub acquisition deal. Already had to merge one thread into this.

Post all news here or find your threads deleted without warning.

This section is a complete mess.

I wonder which foreign country or government would India work with? Hope its the US.

US is not manufacturing conventional diesel electric subs

Yeah , so much for the Rs 50000 crore price tag which TOI had anounced
the value of deal is Rs 30000 crore ,that translate into something like 6.4 Billion USD FOR 6 subs or 1.07 Billion Per Sub
which is quite reasonable considering that we are paying 750 million USD for each scorpene , while these subs will be far more advance than the scorpene , and we also have to take into account price inflation

A serious question.
Why does the mouse of the mods work smoothly to ban indian members?
Why are they so racially motivated?The traditional grudge is reflected in these bans.
However there are sooo less Pakistani members who also indulge in same kind of trolling etc.but are not banned.
There are only a handful of Pakistanis who have been banned.
This is purely bias.

 

[amit27]

cause pakistanis are jealous lol

Calm down and have a glass of water, you are new here, you will get used to the job.

dude i hope you have a second account ,cos youll be needing it soon enough with the progress you are making

India to place $11bn order for AIP hi-tech submarines ? The Register

Indian defence chiefs have approved $11bn of funds to boost the country's submarine fleet. The cash is intended to see India become the first non-Western nation to deploy long-touted, much feared "air independent propulsion" (AIP) submarine technology.

The Times of India reports that 50,000 crores of rupees (500 billion rupees, roughly US$11bn) has been allocated by the Defence Acquisition Council chaired by Defence Minister A K Antony to the "Project-75 India" (P-75I) programme intended to deliver six new submarines.

According to the paper, "all the six new submarines will be equipped with air-independent propulsion (AIP) systems to boost their operational capabilities".

India has a fleet of ageing, conventional diesel-electric submarines and six new Scorpène class subs are already being built there with assistance from French makers DCNS. The first few of these, however, are so far of the Scorpène-Basic type, without AIP, though DCNS says that AIP can be added by the addition of an extra modular hull section during a dockyard refit.

Normal diesel-electric subs, like India's current fleet and most of the non-nuclear boats currently in service, are severely limited in underwater performance. When fully submerged their diesels must be shut down for lack of air, and the sub must then run on batteries.

This cuts speed to a crawl if any range is to be achieved, so much so that adverse ocean currents can prevent any movement at all. A brief sprint at speeds approaching those of normal merchant ships can be made on batteries, but this will run them flat in less than an hour.

These limitations meant that German U-boats of World War II normally had to run on the surface to intercept Allied convoys, a practice that became well-nigh suicidal once radar became widespread. Later U-boats were fitted with "snorkel" or "snort" masts, air-intake pipes which could be extended with the sub at periscope depth so as to run diesels and recharge batteries (mostly) underwater.

Snorkels, nowadays standard kit on diesel-electric subs, aren't an ideal solution. The snort mast is detectable visually or on radar, and hot diesel exhaust shows up on airborne infrared too - though this latter problem can be mitigated somewhat by diffusing it as bubbles through the sea. And the sub still can't go very fast while "snorting", for fear of tearing off the mast.

All this meant that by the end of WWII a U-boat seldom survived to get into range even of the slow merchant steamships of the day. Today's diesel-electric subs have even less chance of intercepting the much faster diesel motor-vessels now in vogue, or gas-turbine warships. Though hard to find when submerged - electric propulsion being very silent - you have to almost drive over such a sub by accident (or sit still for a long time in one place) for it to be a big threat. Even then, a diesel boat has almost zero chance of getting away after making an attack if any competent opposition are about.

The solution as chosen by first-rank navies has been nuclear propulsion, which lets a sub stay under for months on end going at least as fast as a surface ship the whole time if it wants to. Most Russian subs, and all British and US ones, are nuclear-propelled. India has long had aspirations toward nuclear boats, but so far without success.

First Sentence is wrong - Pak already operates an AIP installed Agosta Sub.

I don't understand, why so much secrecy on its capabilities?
I think they will be Hybrid subs with auto navigation, and having maximum stealth features. Linked to satellites for continuous monitoring of of sea passages, ready to attack hostile country from thousands of miles and carrying nuclear tipped ICBMs.
In short the hostile country will have no idea what hit them on the head and from where. In such a scenario imagine what six of them located at different positions on the globe will do.

The biggest question is, which country is ready to work on such a massive Hi Tech project? I think we all know Russia is still the big Daddy of Sub technology in the world, so is it another India Russia JV?

Germany has the best sub technology, both russia and uk obtained Nazi german U-boat scientists which helped their domestic progams. India should purchase the German HDW for Six U-214 submarines with AIP & fitted with brahmos.
