The MDL line is already idling on the backend. Long lead processes for all Scorpenes were completed last year and module fit out is ongoing. Within this year the entire primary fabrication process will be devoid of work. So any follow on orders for Scorpene or otherwise need to be placed NOW...

Which is why I mentioned earlier that the whole plan has been superseded by developments. We already have 2 yards building subs now...MDL and L&T SBC. What is the point of creating skills and expertise in MDL for Scorpenes only to let the line sit idle for another 10 years until 75i is...

The Navy wants a lot of things, many of which are neither financially feasible nor practically logical. Like 3 carriers built to 3 different sizes and designs with 3 different propulsion systems and 3 completely different air wings. Having a 24 hull SSK fleet is not required, having a 24 hull...

Think about it logically, $3.2B projected sustainment for a sub over a 30 year service life is not unreasonable. Especially for a large, oceanic SSK with AIP like the Attack-class Please read into the cost of MLU for our Sindhughosh class and the annual cost of battery replacement. HDW has...

The whole concept of 75i itself is flawed which is why its dragging so long. The requirement for a long endurance, oceanic SSK was drawn up by IN at a time when it was still not conceivable that SSN would be within our reach. They wanted an SSK with near SSN performance to compensate. However...

The figure reported is misleading. A$35B is the total budget allocated to the programme not just the build cost. Means it includes maintenance for 30 years of service life also. Build cost is estimated at A$1.2B per hull inclusive of ToT

For $3B a piece the Russians will sell you a brand new Yasen with 40 BrahMos tubes....SSK is not that expensive. Americans build their Virginia's for half that price.

I don't think anyone in the defense community takes desi media articles on defense seriously. The reporters have no credibility (except a couple of half knowledgeable fellows) and the media houses themselves all have their very well known political bias and pliability. Remember how they tried...

Yes. But the OBOGS discharges the H2 back into the sea rather than storing it and the O2 is also released as a gas rather than having to be liquefied and stored. If intention is to use the products as a fuel source then you would need to add cryogenic cooling and pressurization as well separate...

I never suggested it was practical to use. Otherwise the whole world's sub fleets would be using this method! Free unlimited fuel source that they are swimming through lol Methanol to hydrogen : well thats exactly what MESMA does although they use Ethanol as a source since Methanol is toxic and...

The F21 is pretty close to being AI guided. That being said the limiting factor isn't the torpedo itself but detection and guidance. You can make the torpedo as intelligent as possible but as long as we can't move beyond sonar for detecting and tracking a target it won't matter.

Simple electrolysis reaction of seawater generates Hydrogen and Oxygen. The method is quite simple (can be done at home) but both major products are both dangerous and difficult to store and contain

The long term future of AIP is basically going to be a revolution in battery technology. There are some promising breakthroughs currently being tested withe carbon based battery which can provide sufficient charge to last for an entire 30-45 day submarine mission. The Japanese have already...

Yes I am well aware of the way the system works, I work in naval field myself in engineering. You have to think of the AIP not just as a battery or power source, it is part of a larger propulsion system. The bigger or smaller the submarine, the system in its entirety is scaled according to...

Depends on the type of AIP being used. For eg the German Fuel Cell based AIP is much different from the French MESMA or the Swedish Sterling engine. AIP is a broad term encompassing many different technologies so its important to understand the differences. For eg, in fuel cell system there...

You do understand that AIP is a complete system of machinery which has certain space and weight requirements. It is not a One Size Fits All solution and at this point the DRDO AIP is being designed for fit into Scorpene only (since ToT for the design has taken place) and that too is still not...

You seem to be under the impression that ToT means that the original design holder is basically cut out of the proceedings and the buyer goes ahead and wholesale makes everything in house without any involvement of the partner. That is NOT what ToT is, what you are thinking of is reverse...

South Korea has taken up full ToT of the Type 214 to the extent that their newest batch are actually improved "evolved" design more akin to the proposed Type 216 but without input from HDW themselves. Regarding use of German engine, the engine is built under license by Hyundai based on German...

Your perspective of lost decade would be correct if the technology was on par in the 1980s and stagnated after that. However in reality the Soviets were behind the curve all the way from the 1970s onwards and kept falling further behind. The fall of the USSR only laid bare this huge gap and the...

They used to send chills during the Cold War when the US couldn't get sufficient information from behind the Iron Curtain. However that fear turned slowly to derision once the truth of the matter became apparent. During the 80's the US knew for certain that Russian subs where far inferior to...
