American Tech in Spanish S-80 Plus Subs Raises Concerns for Indian Navy, Particularly ToT

India's pursuit of new submarines under Project-75I is encountering a potential roadblock due to concerns over American technology embedded in the Spanish S-80 Plus submarine, a leading contender in the Indian Navy's tender.

The heart of the matter lies in the extensive use of American systems within the S-80 Plus, including Lockheed Martin's advanced sonar technology crucial for underwater operations. While these systems offer cutting-edge capabilities, they have raised eyebrows among Indian naval officials due to potential challenges in technology transfer (ToT) and integration with indigenous systems.

India places a high value on ToT to foster self-reliance in defense capabilities. However, the integration of American technology complicates this goal, as the extent to which Navantia, the Spanish shipbuilder, can offer a comprehensive ToT package remains uncertain. Concerns about long-term operational autonomy and the ability to integrate Indian-made weapons into the submarine's combat system have also emerged.

The Indian Navy is set to meticulously evaluate the S-80 Plus's performance and seek clarification on ToT terms from both Navantia and its competitor, Germany's TKMS, in the coming weeks.

The spotlight is now on Navantia. To secure the contract, the Spanish company must address the Indian Navy's concerns head-on and present a convincing ToT package that aligns with India's stringent requirements for technological self-sufficiency. The outcome of these negotiations will not only shape India's submarine program but also have broader implications for defense technology transfer in the region.

As the Indian Navy navigates this complex situation, the integration of American technology in a key contender has added a new dimension to this critical defense acquisition. The focus remains on ensuring that any submarine deal aligns with India's long-term goals of self-reliance and technological advancement.

Yes they have been reluctant to give any critical technology or weapons buts recently they have lifted a lot of the restrictions they imposed on us.

Why should india trust german shepherd? It is not like it hasn't barred the supply of military hardwares to Saudi Arabia. Even if "lot of restrictions" are lifted, no one can say for sure these unpredictable buffoons couldn't redo arms embargo in future.

Germany is the wild card of Europe when it comes about their dealings with non-western countries.

If only repeating the lies could have turned them into truth...

Ok then list the TOT, why we couldn't make any more submarines ourself from the TOT offered on Scorpene 😂, we already know how to make a fighter jet, so don't tell that Dassalt taught HAL to make Tejas.

The Su-33 is not a good carrier aircraft, and, as strange as this may sound, is even more obsolete than the MiG-29K is. I agree we should be going for CATOBAR carriers, but the MiG-29K and the Su-33 are both hopelessly obsolete to consider large-scale procurement. If the Russians decide to finally decommission that scrapheap they call their aircraft carrier, we could look to buy a few MiG-29Ks to bolster numbers. The Su-33s are hopeless, though.

Coming to the Tejas N,that aircraft was too heavy for its engine to be suitable for proper carrier operations. The Tejas N, as originally presented, was too heavy to have a carry a full fuel and weapons load, had a bad thrust-to-weight ratio at takeoff, and had issues with the landing gear strength. The Navy had proposed using a different, more powerful engine in the Tejas N, but the IAF and HAL rejected that, claiming this would push development of the Tejas back. That is very much how things have been, with the INAA always becoming the red-headed stepchild to the IAF.

Like Super Sukhoi we could make super SU-33/SU-30M from fresh frames with all the advance gadgets to make those relevant, Rafale airforce variant carry's barely 3.5ton more payload over single engine F-16, due to naval conversion Rafale-M would have added some extra weight that would transalate to even lower payload by 1-3 tons almost equalling F-16's payload capacity, so if in case if we make a naval variant Tejas MK2, it's payload will be pretty closer to Rafale-M payload, so there is not much of a difference between a single engine Tejas MK2 and twin engine Rafale-M in terms of specs, Tejas Mk2 naval could be easily used in a carrier equipped Catapult launch without sacrificing its payload carrying capacity, we just need to give or take here and there, I think Navy rushed too soon without doing a thorough analysis only for the purpose of tips.

 

[Pink Panther]

Zero TOT? When did you return from galaxy andromeda?

why don't you list the TOT then, so that everybody here is aware of.

 

[beencensured]

How can you be so unthoughtful man. Scamgress is talking about wealth redistribution, handing it over to one unproductive community who do not want to work & you speak of brain drain? Really?

Maybe if you can fix regressive mindset and value our county as capable. So, many want handouts, there need to be work done, Value capable people, but instead value is to useless vote bank and that too only too loot as never satisfying the needs of majority. Nehru invented the "tyranny of the Majority" as the bstard did not want to develop the country and do vote bank politics to loot the country. Whereas democracy is majority rule, and majority wants development electricity, water, education, healthcare, jobs and so on.

Why would they work for India when we had emergency and license Raj during their early years?

In fact I would go further educated back then were not wanted and government drove them away from India as it did not want development and wanted only a Conversion Raj. Especially to show off then to west in life magazines the poverty of India.

But realize Trillions of dollars of loss to economy as India is less developed and such talented people were not wanted. People from IIT's could not get jobs.

But how is US responsible for that?

Here is why, drdo aip is not sea proven yet, these things take time often 2-3 or more years. Scorpene is 1990s tech.

Five to ten years, and never used, and so never proven. You type of jokers set a new standard.,

Again, not easy to navalise a fighter directly. You can navalise the Su-30MKI, but the massive size of the aircraft means the weight penalty will be even higher, not to mention that the size will mean a decrease in how many aircraft you can carry on a carrier.

Coming to the Rafale M, one of things France did very cleverly was to design the Rafale M from a stripped out Rafale design. That has allowed them to get the weight difference between a Rafale C and a Rafale M to just under a ton rather than the standard 3-5 tons. Therefore, the Rafale M, when operating with CATOBAR, can carry almost 9.5 tons of payload across 13 hardpoints. In contrast, even the Tejas Mk 2, before navalisation, has a maximum payload of about 6.5 tons.

Now, you could theoretically navalise the Tejas Mk 2. However, that then runs into the same problem as to why the Tejas N was rejected: For the additional weight of a Tejas Mk 2 over a Tejas Mk 1, the F414 engine actually would mean a worse thrust-to-weight ratio for STOBAR for a naval Tejas Mk 2 than the F404 would bring for the Tejas N. There is a massive difference in payload and other operational characteristics between the Rafale M and a hypothetical Tejas Mk 2 N.

Again, any aircraft operating off STOBAR can be made to operate off CATOBAR with some minor modifications. However, considering that CATOBAR carriers for the Navy are still atleast 20 years away, the TEDBF is a perfectly good program. N-AMCA, Tejas Mk 2 N, and Tejas Mk 1 N all have insurmountable issues for STOBAR operations. Oh, and the Navy would have done far more research than you or I before they decided to reject the Tejas N and proceed with TEDBF development.

 

[Anant]

Not to miss another point, Tejas N is a single engine aircraft. If you look at most naval aircrafts, those are dual engined, for the reason of redundancy.

Agreed, Sir, but what happens is that the moment you say that, people immediately point out that the F-35 is also a single-engined aircraft, which is why I tend to not use that argument nowadays, or simply use it as a supporting argument.

 

[Anant]

Yeah, but a IAC2 will eat the naval budget. So building more subs is not possible fiscally.

It's very much possible. IAC-II may cost 3-4 billion USD, but that cost is divided across 10-12 years. Hence, a small increase in capital budget actually accounts for a carrier.

That said, there is only so much capex one can pursue in this way. In the long-term, capital expenditure in the military needs to increase.

it is not 1 ton difference between Rafale-C and Rafale-M, it is solid 3 tons, Rafale-M will carry even lower payload in STOWBAR, Naval Tejas is based on MK1 and not MK2, that we all know has poor specs, but MK2 is only short by 3 tons compared to F16, US even played with the idea of using F16 in carrier doing landing and takeoffs, they have multiple engines for F16 that can increase the payload, especially the engine in UAE's F16, which has roughly the same power as Rafale's Twin engines, so it is quiet possible to use Tejas Mk2 or even a new variant of MK2 with high output GE engines or even single izdeiye-30, it is definitely possible, we don't need to spend $300+ Million to buy a foreign naval fighter, when there is a will there is a way, Disclaimer, this is a hypothetical scenario, what happen's if China bombs on one of our carriers packed with 24 Rafale-M's in one kill and sunk it, we have to make an order of 24 new Rafale-m"s and wait for 15 more years, this is why we need few different kinds of locally developed Naval jet's, single engine jets save us a lot of money compared to twin engines.

Not true.
Too many posters with Rafale-M stars glowing in their eyes so they keep blowing sunshine up Rafale-Ms fanny regardless of cost, available armaments, etc

 

[Pink Panther]

Five to ten years, and never used, and so never proven. You type of jokers set a new standard.,

He means not proven at real time in Submarine, so far it has been proven only in test lab, testing in realtime might throw a lot of challenges that they might have never anticipated in lab, we need to a give a old retired sub to DRDO for testing purposes.

 

[Pink Panther]

Not true.

Also Rafale-M has a specific requirement to use Mistral, it can't use the missile same way as Rafale-C variant, which is again a drawback.

I mean they suppose to fit the last sub, but they choose not to. They play these game of self defeat. Still untill you use it, how can it be proven. Just making a joke like an old sub would not have a crew. New sub have less maintenance issue. So, another irrational comment hust to delay induction on behest of Pakistan/ China/ and everyone not wanting India as superpower.

 

[beencensured]

Finally someone said it. Unlike France or Germany this s80 product is supported by American submakers. It has too many American and british components. Its spanish design , but also too many countries involved.

But we have our own sonar, and etc. It gives more to greater percent indigenous.

"Number one enemy"? What are you eating these days? US is unreliable but not an enemy. Thought Bharatiyas knew their no. 1 enemy is china. Seems some are still in the dark & stumbling very badly.

China does not poach our best and brightest, and assassinated two our pm Lal Bahadur Shastri Indira Gaannddhhi, involved in genocide in Pakistan like 1971 war, send terrorist like they did in Kashmir and Punjab, do 26/11 like with CIA operative David Headly., but does support terrorist Pakistan/ Taliban.
