IN Scorpene Submarines - News & Discussions

Can we stick to the topic guy's .

Sorry.

I think your post about the desire for tot was really good. But India has huge wealth, if a sub is for sale then it's technologies are for sale. Indian military needs to focus on simplifying it's logistics train and maintenance complexity. More of the same even if they are not quite as good as other things. Your poor technicians and mechanics. Too many things.

Yes we are really bad on logistical part just look at our air force mixed with so many different aircrafts and air defence grid is also mixed with products of different oem and guns also we have at least 10 different types of guns.
We used to be biggest importer of weapons and because of that this fuck up happened.
Actually this is the basic reason why we want to create this whole make in india thing to get start manufacturing arms in india itself so that we are not dependent on OEM because they charge way more when the origin country stop using those equipments.

Yeah buying. But buying from everyone because...you bought to satisfy others. See how broke Greece is still buying weapons from Germany and France? Similar thing.
10 different guns is a just a tiny part of your problem. Imagine the engines! Jet engines have how many parts? You have how many different jet engines? and that is just the engine. OMG. You have 5 or 6 types of subs all with different parts and different repair manuals. OMG.
I wonder what the military of the US personnel ratio is between soldiers, technicians, mechanics and logistics compared to India.

That's the reason why we all are discussing ,these problems.

That's the reason for inclination towards french design ,older submarine will retire in upcoming decade , what will be left are scorpene class ,followed by p 75i and it's follow up indigenous design ,with much commonality to above two , Russian design will be decommissioned as they are old as hell.
Iaf is trying to standardise , but will take much more time , army.is the biggest mess

DRDO's Fuel-cell Based AIP System For Submarines Achieves Important Milestone After Tests
The Defence Research Development Organisation (DRDO) on Monday successfully operated the power-plant that has been developed for the Air Independent Propulsion (AIP) system to be used in submarines by the Indian Navy. The Naval Materials Research Laboratory of the DRDO was developing the prototype, a release by DRDO read Tuesday.

AIP executes a force multiplier effect that makes carrier boat dangerously lethal
The plant was operated as per the user requirements in two modes — endurance mode and max power mode. The system developed by NMRL is equipped to execute a force multiplier effect that enhances the lethality of a diesel-electric submarine, by further boosting the endurance of a boat while it is underwater. This AIP has been designed using fuel cells that is an add-on for its performance when compared to other technologies. The fuel-cell-based AIP is also unique because unlike other systems in use globally, the one developed by NMRL can generate hydrogen onboard.

Meanwhile, L&T and Thermax collaborated with NMRCL to develop the technology that has now evolved to the stage of maturity. The AIP is now ready to be fit into target vessels. Defence Minister Rajnath Singh hailed the efforts of DRDO and NMRL, while he congratulated the Indian Navy for yet another addition to the Indian submarine section.


Dr. G Satheesh Reddy who is the Chairman of DRDO called upon the fraternity to innovate more such advanced technological achievements.

DRDO Develops Air Independent Propulsion Technology for Indian Submarines
India’s Defence Research and Development Organization (DRDO) said it completed the final development test of Air Independent Propulsion (AIP) that allows diesel electric submarines to remain underwater for longer periods besides making them “quieter,” on Monday night.

“DRDO has achieved an important milestone in the development of AIP System by proving the land based prototype on 8 March 2021. The plant was operated in endurance mode and max power mode as per the user requirements,” the company announced.

The system is being developed by Naval Materials Research Laboratory (NMRL) of DRDO. The technology has been successfully developed with the support of industry partners L&T and Thermax.

AIP enhances the submerged endurance of the boat. Fuel cell-based AIP has merits in performance compared to other technologies. While there are different types of AIP systems being pursued internationally, fuel cell based AIP of NMRL is unique as the hydrogen is generated onboard.

It has now reached the stage of maturity for fitment into target vessels. The Indian Navy can now retrofit all of its Kalvari-class submarines with AIP during their first upgrade, expected around 2023.

One thing we took wrong, for P-75I neither we were offered Amur 1650 not SMX 3.0. This case is different.

Big talks , isro too developed li ion battery , japan was offering li ion battery too , and how come they be most advanced in world when japs have deployed a submarine already .


And what ype of aip they use in it

 

[Lonewolf]

@BON PLAN , can france offer a enlarged scorpene of 2700 ton with drdo aip , vls , electronic and sensor from barracuda short fin , and pumpjet propulsion

All is possible. But Scorpene means the actual hull diameter : not good for VLS I think.
A shorter design than Barracuda, but with the same diam to fit the famous VLS for Brahmos is possible I think. I see no technical problem.
The Shortins Barracuda drawings are probably the Australian Govt property, but Barracuda (SSN) is a 100% french design, so any derivative even only slightly different than Shortins one is possible.

Read it it's the highest ever 18 days

Read it it's the highest ever 18 days

Quoted figure are not actual , drdo one us quoted 14 days , but actually more than that , same for each and every aip

How do you know?

 

[Lonewolf]

How do you know?

Check up the power production ,the normal usage of power during underwater , they amount of fuel for fuel cell it carries , the figure from osint about how long it remained underwater during patrol ,these are kept somewhat understated , don't know why , even though enemy know almost about it's capability
