Naval Group's Propulsion Systems: AIP for Submarines 

Thank you Xavier.

One of the main goals of fuel cell tech is avoid dependence from petroleum but this one still uses diesel to extract h2. But performance wise, this might end up an exceptional tech for military use

If the Philippines those select the Scorpene-class submarine (assuming it gets funded and pushes through), i'm hoping the follow-up scorpene will have AIP for longer underwater patrol and make it harder to detect.

This is the video I was looking for as very few videos on Naval Group FC2G AIP were available thanks for this video Naval News! How much does this AIP module cost? Will Naval Group fit this FC2G AIP module + Li-Ion batteries on Scorpene Class Submarines? In context of Kalvari Class of Indian Navy.

Ideal would be to go to snorkel depth occasionally when safe to do so, suck in air and remove the O2 and store in the cryo tank for another 3 weeks submerged.

Will we see this incorporated into the Australian sub contract? You would think that this was tailored for Australian and Indian requirements!

Please clarify that nuclear power is also AIP. You're really producing QUIETER AIP. Sensitive PASSIVE sonar (listening only) is the threat here. Lithium batteries alone are an even quieter form of AIP. The key question: what is the noise penalty for adding the FC2G to a lithium-alone solution?

The French submarine order was sunk today. The US is supplying nuclear submarines to Australia.

How is the oxygen from the oxygen module recharged? in port or in snorkeling operation?

How much to retrofit the AIP into Scorpenes that's already running for navies?

Heh, getting recommended this after the US swooped in and took the Australian contract.

This system might end up replacing the batteries in diesel-battery hybrid powered surface ships for low speed drive. No more recharging... 2 large diesel engines for high speeds + F2CG for low speeds...

Australia should be mature enough to accept that nuclear power is the most appropriate power source for the size of submarine, not redesign the French submarine so that it is conventionally powered. If Australia accepted nuclear power, the US would have supplied the subs with a US combat system. The US has told the Australian government they will not put US combat system technology in the French design for security reasons. Australia was told not to order the NG design but the government ignored all the critical analysis.

It's essentially good, but please clarify that nuclear production is also AIP. You're producing QUIETER AIP. (Lithium) batteries are an even quieter form of AIP. PASSIVE sonar is the threat here.

the argument against hydrogen is valid in a warship.

Problem with lithium batteries is risk of explosion during combat 😂😂

seems overly complicated and with so much steps i wonder how efficient all this is... seems sweden got better solution. much simpler and probably cheaper too

No fuel cell no AIP

Australia to go nuclear submarines

You can’t put little lithium ion batteries in checked luggage on an airplane because of risk of fire, but you’re going to put a giant one on a sub with a great big tank of liquid oxygen? I spent 10 years on subs. No thanks.

Are you putting this propulsion in Australia’s Barracuda Class when you deliver them in 50 years , over budget and too late to use against the Chinese?

Any submarine propulsion system that requires tanked oxidizer is not AIP. Right now, the only REAL AIP system is nuclear propulsion. However there may be ways of building real AIP. I'd try extracting dissolved oxygen from the ocean water.

Please ditch the terrible music in the background. It just makes it harder to listen to the interview.

A real shame that Australia bailed out of the French submarine contract. The one billion plus it cost Australia was a bit of a blow but the French submarine was the best option for our country. How to win friends and influence people is not a book that is mandatory reading for Australian politicians especially in defence deals. Using the FC2G AIP which uses diesel fuel reformation to create power paired with GS YUASA Lithium-ion submarine batteries or the new South Korean lithium-ion submarine batteries or fuel cells with the diesel engines used for charging the batteries when snorkeling and surface running I had calculated around two to four weeks submerged at cruise speed without snorkeling or surfacing. Using a direct drive electric motor and a new design for the dual contra-rotating propellers on the same axis for propulsion with anechoic tiles on the hull for noise reduction. I have a few new ideas for the way the submarine propellers and or propulsion systems can be built that hasn't been tried before. A Thales sonar system and decoy launchers could be used to help finish the design. Three types of weapons can be launched from the torpedo tubes. An F21 torpedo an Exocet SM39 missle and an extremely fast MdCN cruise missile with the option to lay sea mines available. The AIP has no depth limitations and the submarine design is slightly quieter than a nuclear submarine when submerged and well suited to Australian requirements. The AIP module shown above is sized for retrofitting to existing french submarines but custom sizes can be built. The overall design is a little bit more complicated than I have described but the engineering is sound. The price has ended up increased to eighty billion for french submarines with the current estimates at three hundred and seventy billion for AUKUS nuclear submarines. Nuclear power has been banned in every state and territory in Australia for many years. The decision to cancel this contract and go with nuclear submarines is not popular with the majority of the Australian general public. The decision is purely to appease the UK and US with an extremely expensive price tag required to sit at the big boys nuclear table. The performance increase a nuclear submarine brings to the table compared to the design described above is not worth the extra money. The UK or the US can't start building Australia a custom nuclear submarine for at least a decade and leasing any from the USA is unlikely at this stage. A huge mistake from Australia with US and UK ass-kissing leaving a big capability gap and making us look like idiots. I am sure many countries will be interested in this AIP and french submarines going forward but a bit more warily than before after the furore with Australia. I hope the new submarines that the Netherlands are having built are of a very similar design to how I have described them above. 😎🇦🇺👍
