SMX Ocean is the name of the concept in general. Shortfin Barracuda is an Australia-specific sub named after an Australian fish of the same name for the Australian competition.
So ours will be Pomfret or Surmai?
 
That's most definitely a typo. ;)

The best case for us is if L&T builds the new subs, regardless of which sub is chosen in the end.
If its Naval Group winning, then better to expand and improve upon MDL facilities, as costs will surely be less.

If SAAB of TKMS wins, L&T all the way.

Personally don't want Russia, Spain winning it, nor i see how it may happen.

Actually, we need MDL to build our next line of indigenous subs. So, while L&T, or any other private player, builds 6-12 P-75I, MDL can be involved in the design and construction of the next line of 6-12 subs of indigenous design. In the meantime, we should see if MDL gets another order for 3 more Scorpenes.

I don't want the Russians, Spanish or even the Scorpene winning. That leaves Germany and Sweden.

Anyway, the Amur 1650 will likely not meet full ocean-going requirements.

6-12 to L&T with MDL getting another 6-12 later in the day? All this while the capex in the defense budgets continue to be modest. We haven't even exercised the + 3 option for the next Scorpenes.

The cost for those subs will be peanuts in comparison to the defence budget when they are all actually ordered.

P-75I will actually be ordered when we are a $4-5T economy. And the indigenous subs will be ordered when we are a $10T economy. And the projects will finish when we are well above $20T economy.

Why did we make a Second line for Submarines at MDL , if it was to kept idle
And Empty

I bow to thee , O bearer of news of good fortune in the future. Charandhool bhejiye, gurujan. Address PM karta hoon.

Meanwhile Bejan Daruwalla is about to kick the bucket. He needs a worthy successor. He also predicted RaGa would be the PM. When confronted he claimed Rajiv Gandhi was RaGa. That he made the prediction after Rajiv Gandhi's death is incidental.

He also claimed Dhirubhai Ambani is the world's biggest philanthropist. He isn't wrong, you know, when you consider toddy tappers like @Guynextdoor laugh all the way to the bank. Is there a greater method of enrichment than socialism?

Sure, we'd do all you describe. If not in the same time span then a few years later.

🙏🙏

Yet another submarine design from Malachite - P750B small attack submarine - designed for anti-submarine operations, special missions support and inshore defence.

Shrouded six-blade prop, range of 1400nm on AIP power, twelve 533mm torpedo tubes in a removable frame for easy maintenance and reloading, 20 man crew and provisions and space for 16 special missions capable crew and equipment. 65.5 meters long, estimated 2000 tons submerged. Interesting design.

ru_P750B_model.jpg

ru_P750B_Stern.jpg

Specifications
Displacement: 1,450 tons surfaced, ~2,000 tons submerged (est)
Length: 65.5 meters
Beam: 7 meters
Draft: 5.2 meters
Speed: 18 knots submerged, 4 knots cruising
Range: 4,300 nautical miles normal, including 1,400 nautical miles on AIP (Air Inpependant Power)
Endurance: 30 days. 12 days on AIP @ 4 knots, 3 days on batteries alone.
Operating depth: 300 meters
Propulsion: 2 x 400 kilowatt gas turbines (AIP), 1 x 2,500 kilowatt electric motor
Crew: 20
Passengers: up to 16 Special Forces
Armament: 12 x 533mm (21") torpedo tubes for torpedoes, missiles or mines

Russia's 533 tubes typically accommodate either the USET-80 or UGST of the Type 53 heavyweight torpedo family or Shkval. Cruise missiles are optional, but often not carried on smaller boats due to limited space. Apart from Shkval, Russian torpedoes are largely wake homing against surface vessels and active or passive acoustic homing against submarines. Let me know if anyone wants an explanation on the difference between active and passive acoustic homing.

As always I'm mystified why Malachite continues to evolve submarines with shrouded props. For the P-750B design it makes sense when you consider its inshore defence and special missions support focus, where speed isn't as vital and stealth, but it's an interesting trend Malachite continues with at a time when Russia's other sub designer, Rubin, has transitioned over to pump-jets.

Like Malachite's other designs I expect this to garner little interest internationally. Still nice to see another design.

Why no more Scorpene ? Don't make the same error than with Mirage 2000 or Mig29 : too small fleets (at the Indian scale)

Because if Scorpene is chosen, then only MDL will build it. We need a second line of submarines, which will never happen with Scorpene. Not to mention, the entire idea behind Strategic Partnership is to give contracts to the private industry.

Also, even if the fleet is small, we still cannot put all our eggs in the same basket when stuff is imported, it leads to unpleasant situations in the future when we have to negotiate for upgrades. Monopolies are very bad for a country the size of India.

There's still the option for 3 additional ones to be exercised. Moreover, if the SMX Ocean is chosen for the Project 75 I & there's a good chance it may be, it'd go against the face of all that you're arguing for out here.

In what way?
For one, if the SMX Ocean is selected, it means for the forseeable future, we'd have "put all our eggs in one basket " - the French.

For another, if the SMX Ocean is chosen, given certain commonalities with the Scorpene and the massive infrastructure created at MDL, it'd make sense for the GoI to go in with the MDL particularly so as to make up for fast replacements of the Kilos and the HDW subs inevitable in the 2030's, something which would be time consuming if this project were awarded to the Pvt Sector - the goal of MoD in keeping with Make in India ( MiI) & creation of an alternative to the PSU's.

Of course, the project could also be split between a PSU & the Pvt Sector, which I suspect is what's going to happen. This move would make more sense if the total procurement under Project -75I would be 12 subs - another likelihood.

Honestly, I'd prefer the A26. But the SMX Ocean is so good that it's worth going back to the French. The price and capability of the SMX Ocean sits between an A26 and an SSN. IN will have to decide whether they want the extra capability of the SMX Ocean. My point is, close eyes and buy SMX Ocean, or buy A26 if it's competing with the Scorpene.

A kickass option would be to buy the SMX Ocean now and then upgrade it with a nuclear reactor when it comes in for MLUs.

There is no commonality between Scorpene and SMX Ocean.

Anyway, if the 3 follow-on Scorpenes are ordered, MDL will take at least 7-10 years to deliver. In the meanwhile IN will get busy with an indigenous sub design. By then a new 30-year submarine plan will be laid out, until 2060. We will easily need 50+ new subs in the new plan. That's when we will need MDL and a private company making subs to meet our requirements after 2030.

Of course, the project could also be split between a PSU & the Pvt Sector, which I suspect is what's going to happen. This move would make more sense if the total procurement under Project -75I would be 12 subs - another likelihood.

That won't happen. It will be 6 with a follow-on 6 given to just 1 yard.
