Since the much hyped, media covered and backed French Scorpene submarines seems like not heading any where and the retarded Indian mentality of the western goods being 'superior', the one part that we Indian's have failed to see is the family of very capable Russian non-nuclear submarines of the Amur family, because of the newly acquired international 'friends'. But, India and Indian's have ignored and forgot the very basic fact that an old & trusted friend - even though struggling and considered penniless - is always better than two new friends. But the bitter fact about this is, ignoring the basics have always resulted in paying heavy price.
The first submarine is the one we already knew - Amur-1650, as that was one of the likely candidate (and still is) for I.N's submarine fleet. The options from this submarine are -
1) Amur-1650 Basic ; which include the torpedo tube fired Klub
2) Amur-1650 with AIP (Air-Independent propulsion) module; this include longer submerged endurance in addition to Klub.
3) Amur-1650 with BAC (Brahmos Amur Complex) module; which include a 8-cell VLS for PJ-10.

Amur-1650 spec
Number of torpedo tubes, ------ 6 pc
Missile, torpedo and amine ammunition, ------ 18 pc (calibre -533 mm)
Normal displacement, ------ 1765 m3
Principal dimensions,
- length ------ 66,8 m
- breadth ------ 7,1 m
Full submerged speed, ------ 21 kts
Submerged range at economic speed, ------ 650 miles
Cruising range with overload fuel capacity while snorkelling at economic speed of 7 knots, ------ 6000 miles
Maximum diving depth, ------ 300 m
Endurance, ------ 45 days
Crew, ------ 35 persons
The second from the Amur family is the Amur-950, which did not actually cross the Indian minds untill now. The second member of the Amur family is the new variant --- Amur-950 Version-2.
The V2 differs from its earlier version with the addition of a killer module aka a 10-cell VLS for PJ-10/Klub, showing as who sets standards for the SSK's of world.

Amur-950 V2 was actually displayed at DefExpo'04' , which unfortunately did not get much attention or coverage ...
Amur-950 V2 spec
Number of torpedo tubes, ------ 6 pc
Missile, torpedo and amine ammunition, ------ 14 pc (calibre -533 mm)
Normal displacement, ------ 1060 m3
Principal dimensions,
- length ------ 60,3 m
- breadth ------ 5,6 m
Full submerged speed, ------ 20 kts
Submerged range at economic speed, ------ 350 miles
Cruising range with overload fuel capacity while snorkelling at economic speed of 7 knots, ------ 3000 miles
Maximum diving depth, ------ 300 m
Endurance, ------ 30 days
Crew, ------ 18 persons
Probably the outstanding capablity of the Amur-950 it is that, its possible to fire a a salvo of up to 10 missiles in one salvo from under the water. Torpedo weapon includes 4 torpedoes in the 4 forward 533 mm torpedo tubes plus 2 spare torpedoes. Not bad either, considering that this is meant to take out the surface fleet and for that task, in our case we can expect out surface fleet and the air-cover.

I.N's current fleet of submarines will be decommisioned in the next decade so most of the induction will go towards maintaining the fleet level. For augmenting the fleet we've got 2 really good option to choose from the Russian side, if anyone really cre to. Actually these two subs are not an 'option' , but it could be supplimenting each other for two set of roles.
The roles that these two can be dedicated to, are -
1) National defence (the 'inner circle') & western area of 'interest'
2) Expanding the 'reach' to protect India's National intrests in the areas's 'concerned'.
For these two different roles, we get two very capable platforms in the form of Amur-950 V2 (Role-1) and Amur-1650 modified (Role-2). The very common thing abt these two other than coming from same Country of Origin, Design Buearua and Family of submarines would be that, these two will be equipped with VLS for Klub/PJ-10, making it the most promising & cost-effective solution for a large volume sea-denial capablity & pre-emptive strike on land targets. These are one amoung the many capablities the competition can't provide, and wont be having in the near future.
The other options that we can have come along with there two submarines are -
1) Amur-950 V2 equipped with an AIP module (Kristal-2E) which will augment the submerged endurance for this killer.
2) Amur-1650 with N-propulsion. This wud be a good option, as an Amur-1650 with two modules (AIP & PJ-10 complex) might be heavier which could make it slower. This cud be somewhat like what the French have with the N-subs, but with a much capable platform and arsenal in the form of a N-powered Amur-1650.
