Indo-French naval exercises ‘Varuna 2018’ kick-off at MPT


NN | Mar 20, 2018, 03:27 IST

Vasco: The Indian Navy will get an opportunity to put its recently inducted Scorpene-class submarine, the INS Kalvari, through its paces and simultaneously gain from the French navy’s operational know-how during the Indo-French naval exercises, Varuna 2018. The bilateral maritime exercises began on March 19 at the Mormugao Port Trust (MPT), Vasco, with the harbor phase, and will continue over the next two months.
THe INS Kalvari, a conventional diesel-electric submarine, was commissioned by Prime Minister Narendra Modi in mid-December 2017 and has been designed by French firm DCNS.

Naval sources said the Indian Navy is keen to enhance INS Kalvari’s operations for anti-surface warfare (attacking surface ships) and anti-submarine warfare (destroying submarines) in the Arabian Sea and the Bay of Bengal, especially since Chinese submarines have been foraying into the Indian Ocean Region (IOR).

Over the past two years, People Liberation Army Navy submarines are frequently present in the IOR, making periodic forays into the Arabian Sea.

“Maritime security is a priority of our defence and security policy, alongside the fight against terrorism,” joint commander of the French naval forces deployed in the Indian ocean rear admiral Didier Piaton said. “As a strong symbol of the strategic partnership, the Varuna exercises aim at strengthening the common knowledge and the interoperability of both, French and Indian navies.”

France has brought its nuclear attack submarine FS Perle and the anti-submarine warfare frigate Jean de Vienne for the exercises.

“The Jean De Vienne is ready for operational know-how exchanges with the three Indian vessels participating in the exercise — INS Mumbai, INS Trikand and INS Kalvari,” Piaton said. “For the next four days, our sailors will evolve through different scenarios conducted during a combined anti-submarine exercise, air defence exercise, firing, asymmetric warfare and other exercises.”
“Maritime cooperation between France and India will be crucial to maintain the safety of international sea lanes for unimpeded commerce and communication in accordance with international law, for building maritime domain awareness and for greater coordination in regional and international fora in the region,” said flag officer commander Western fleet rear admiral MA Hampiholi.

The navies of India and France will hold the bilateral maritime exercises in the Arabian Sea, the Bay of Bengal and South Western Indian Ocean till May.
The Indian Navy’s P8-I anti-submarine aircraft, Dornier maritime patrol aircraft and Mig 29K fighter aircraft will also participate in Varuna 2018.

South Korea eyes French design for indigenous nuclear sub



https://www.defensenews.com/industr...esign-for-indigenous-nuclear-sub-sources-say/

Apparently it is legal for France to sell our nuclear submarines without breaching nuclear agreements.

"According to another informed Navy source, the KDN report referred to the Barracuda-class submarine as a model because the French sub, designed by DCNS, is powered by low-enriched uranium. “The use of uranium with over 20 percent enrichment for a nuclear-powered submarine could breach a nuclear agreement with the U.S.,” the source said.

“In that regard, the French submarine model is realistic and safe to secure nuclear fuel,” the source added.

Under a revised U.S.-South Korean nuclear deal signed in 2015, Seoul is not allowed to enrich uranium and reprocess spent fuel for military purposes. The deal allows enriching uranium for civil nuclear energy and low-enriched uranium."

What? We hav indigenous submarine program?
Um yeah. INS Arihant(S2) you obviously know
Then comes 3 larger submarines dubbed S3 , S4,S4*
Then comes a new much larger class dubbed S5


https://defenceupdate.in/indian-nuclear-submarine-plans-new-s5-class-submarines-coming/

Apart from that there ais a New Class of 6 Nuclear Attack Submarines under developement - https://en.wikipedia.org/wiki/Indian_Navy_SSN_programme

So apart from the INS Arihant and 6 Kalvari Class(Scorpene Class) , I could see atleast 10 more Submarines joining the fleet by early 2030s.

So with all that, yeah, short on money. But we do have plans to develop an Indian Diesel Electric Class of Submarines as well.

Arihant class is not a attack submarine. Only confirmed order is 6 scorpene submarines. Other projects in paper. Going by our defence procurement process it will take another decade to even select A new submarine. So better we order another 4 scorpene now. Otherwise it will take 10-15 years to induct new submarine

Navy Chief Admiral Sunil Lanba, while replying to a question, said on Friday, “We have launched the project to make six SSNs (nuclear-powered submarines) and I will not say any further as it’s a classified project.”

We rather go for Indian Developed.
I just hope for India that it will be more fast and fruitfull than Tejas :confused1:

The 5th Scorpene is already on production. If you don't want to loose the shipyard skill, hard to obtain, it's nearly too late for a follow on order.

Here is the picture of possible pump jet propulsion for the kilo class submarine...............

Pump jet outlets can be seen as the hole immediately right next to the right of the propeller and below the tail plane.
Or may be the exhaust outlet.:confused1:

No, it's a classical sabre blades propeller.
They put a tarpaulin on, to hide the number of blades, which is an important news for ASW

I'm not talking about the skew blade see in this pic

Russians experimented with prototype pumpjet on one of their own Kilo boats in the 90's but did not develop it further as they found the system did not provide optimum performance at the slow speeds that SSK usually operate at.

The technology is currently seen on Borei SSBN and may be seen on Yasen-M follow on.

The outlet you're looking at is a dump vent for cooling water.

Actually, 6 Kalvari and 6 Arihant class will be out by 2020 and more orders will have to be placed to ensure expertise is not forgotten. Considering the pace of development - 12 subs between 2014-2020, I would expect much more submarines in addition to these 12 by 2030.

Maybe the scorpene itself will be made but with all the parts made in India and no imports from France. After all, the design is fully known to India already and can simply be copied with minor changes. The current scorpene batch was assembled in India with gradual increase in indigenous content and the last submarine is expected to have indigenous content of 60% or more. SO, now the next batch can be made fully Indian by making remaining 40% in India

Nuclear weapons are prohibited from being sold. Nuclear submarine may not be a nuclear bomb, but it is a military vehicle with nuclear technology and hence will not be allowed to be sold.

French SSN use a low enriched uranium : it avoid some export nuclear rules ! (clever the french)
