France's future class of nuclear-powered ballistic missile submarines (SSBN), known as SNLE-3G, began construction in March 2024, when Naval Group cut steel on the first of four boats, at the submarine shipyard in Cherbourg, Normandy. In this interview, Anne Bianchi, SNLE-3G program director at Naval Group, discusses the important milestone and shares some details about the four next generation submarines which will ensure the French sea-based nuclear deterrent until the 2080ies.
=====================
At first glance the new submarine is similar in size and form to the current Le Triomphant-class. But it is an entirely new design and is actually almost 10 meters (30 ft) longer (about 150 meters in length, 15,000+ tons displacement submerged, but official figures are still classified). The crew complement (110 sailors), number of SLBM silos (16x) and torpedo tubes (4x) will remain unchanged compared to the Le Triomphant-class.
The main driver for this increased size is stealth. The machinery space will be longer to incorporate an even quieter machinery. This may have some technologies already found on France’s latest nuclear submarine, the Suffren-class attack submarine. Outwardly these include the X-form rudders and pumpjet propulsor.

So the uranium fuel used in the reactor is 20% enriched? How many years will it last without needing to be replaced? 20 years? 30 years?

@dan7564 3 месяца назад

The Aukus reactor for the new British submarine is 90/95% enriched and that's only going to last 30 years, so it's probably more like 7 years like their old reactors.

@@docteurlowbat The fact that French nuclear submarines operate on nuclear power with uranium enriched to within 20%, the same level as commercial nuclear power, is publicly known and is known to any military geek. How is that classified information? Incidentally, the enrichment level of uranium fuel in a small nuclear reactor recently developed by Japan's Mitsubishi Heavy Industries has not been made public (it is commercial, so it is within 20%), but the operating life is 25 years. It is believed that it can be operated with almost no refueling.

Dosen't really matter since subs will always need major mid life maintenance refit, they change the fuel when in dry dock, where and when they would be anyway

@marcsetmais7598 3 месяца назад

The problem with the French and UK nuclear deterrence is that 4 submarines is just not enough. It is impossible to have this number operational at the same time. With two submarines operational and some nuclear capacity on fighters nuclear deterrence might not work very well. Two submarines are easy to detect and the fighter planes are vulnerable and have limited range. A serious nuclear power needs bigger numbers and a more various capacity. But that’s not feasible for the UK or France. The EU as a whole could do this but I don’t see that happen: who is going to press the button (although I hope that will never happen)? Still I think that both countries should stick to their nuclear striking capabilities. It’s geopolitically still important and a bit is better than nothing.

@harrysheffield624 2 месяца назад

I take your point, but with 4 subs it allows 2 subs to be on patrol at difficult times. In UK's case each sub has 12 ICBM's and for France they have 16 ICBM's. When you tie in the fact that each ICBN is MRIV fitted, the number then add up. So 4 subs do work well in offering a credible deterrent.

@lordtemplar9274 2 месяца назад

It is enough to always have 1 at sea, possibly 2. The whole point of sub based deterence is that they are nearly impossible to detect in vast oceans. It's not WW2 when subs had to surface and could be spotted by planes. When leaving port, subs are escorted out to sea by frigates and aircrafts so they cannot be followed/tracked. Then once in open waters it is basically impossible to know where they are, except for dumb luck and dropping sonobuoys exactly at the right spot in the middle of the Atlantic. Much easier to detect said aircraft so the sub can take evasive maneuvre. They still haven't found MH370 in the Indian Ocean, so good luck with a stealthy sub. Considering 1 sub can carry enough warheads to strike every major city of any country (16 missiles each with MIRV) , you don't need a dozen subs at sea.

@ChristianSamsel 3 месяца назад

They build the submarine for more then 10 years?! Crazy

@adrien5834 3 месяца назад

The goal is to keep the workforce busy all the time. If they built them faster, they'd have to lay off the workforce between boat generations and lose the expertise every time.

@ferittuzer4629 3 месяца назад

seems it is a small increment

@johnjeanb 28 дней назад

@ferittuzer4629 this is not about an increased size (quite the opposite) as in many places of the oceans having large submarines is a hindrance (e.g. the continental plateau around Europe). The point is rather to totally update the technology and make room for future upgrades in the 40 years of the life span of the sub (new missiles, new sensors, new computer, new weapons, etc).

@@NicoMCH666 Don't be ashamed. First, we are French and we have an accent. Like any American has an accent when he speaks French. Secondly, I learnt that this accent is an especially "working" accent for French when they work with English or American partners. Because this is the only way to be understood by American and English. The frequency of our native language, makes us speaking english as a incomprehensible "salad" when we try to get an "Atlantic" accent and try to explain very technic things in English.

France designs and builds their own missiles. The SSBNs are completely under French control. The British and US subs draw from a common missile pool. The UK's missiles are fitted with British warheads, ensuring the UK's control over their own subs.

@ianmcsherry5254 3 месяца назад

There is literally no scenario where Britain might feel compelled to launch nuclear weapons and the US would not also be giving it consideration. That would be in response to an inbound enemy attack, or confirmed threat of same. Britain is never going to unilaterally use these as a first-strike weapon. You might equally argue that our F-35 strike aircraft are at risk of the US witholding vital software upgrades, but that's not going to happen either.
