Thanks for watching!

It will only take one of the UK’s new Dreadnaught nuclear submarines to wipe out just about any country off the face of planet Earth and they’re building four of them but it’s not their nuclear missiles that has caused outrage right through the United States military chain of command it’s the stealth capabilities

That the UK refused to share with their friends across the pond the US has the right to be furious because these stealth capabilities make the Dreadnaught class the stealthiest submarines in in the world and of course this is the most important feature of any submarine they’re not called The

Silent service for nothing Jack and I are going to give an in-depth look at the Royal Navy’s most advanced submarine of all time we’ll talk about the Innovative facilities that improve crew welfare the sheer power of the nuclear missiles on board and what that would look like for his Majesty’s enemies and

The Cutting Edge stealth capabilities that set the Dreadnaught apart from every other submarine under the surface so Jack are you ready I can’t wait the name dreadnots in The Royal Navy goes all the way back to the 16th century the first dreadn fought under Sir Francis Drake against the Spanish

Armada the name itself means to dread not or fear nothing but I think the most famous dreadn is the battleship that was launched in 1906 she completely revolutionized Battleship design and rendered every Battleship that came before her obsolete the first nuclear-powered submarine that the Royal Navy operated was given the

Prestigious name HMS Dreadnaught and so it’s apt that the next generation of nuclear-powered ballistic missile submarines are named the dreadn class but James why are submarines so important to navies today yeah great question submarines are effective because they can strike their enemy without being seen they can attack

Targets in the water and on land some submarines carry nuclear weapons that make them even more devastating to their enemies a lot of work goes into helping surface vessels locate submarines and a lot of work goes into making submarines harder to locate but it’s the stealth capability that sets the dreadn apart

From submarines that other countries operate so the dreadn class are what’s known as nuclear-powered ballistic missile submarines or ssbns nuclear power effectively gives them an unlimited range they won’t need to be refueled over their 35 to 40-year lifespan only a handful of countries have the capability of building an operating nuclear-powered submarines and

They’re expensive too each submarine is going to cost around 7.75 billion pounds or $99.75 billion that’s over twice the cost of the Royal Navy’s Queen Elizabeth clous aircraft carriers the dreadn submarines will have a displacement of 17,000 tons a length of 153 M and a beam of 12.8 M

They’ll be some of the largest submarines in service in the world but a boat that big is going to require a huge crew to run it how many people will be on board the boat’s company will be 130 men and women and the dreadn submarines will offer some fantastic facilities

That previous boats haven’t yeah there’s much more emphasis on crew welfare the new submarines will use a Cutting Edge lighting system that will simulate day and night they’ll have a medical center a dedicated study area and even a gym that has bikes rowers treadmills cross trainers and weight benches the crew are

Going to come back from their deployment fitter than when they left but it’s not only that these will be the first submarines that are designed with women in mind they’ll have separate female crew quarters toilets and washing facilities all they need now is a couple of Windows and it’ll be just like being

On a Surface vessel yeah I think Windows would be a great morale booster the first of these submarines is expected into service in the early 2030s and for what might be the first time ever they’re actually running on time and on budget now it’s time to look at the

Armen on board these next Generation City levelers how much damage could they actually do well they have four torpedo tubes that can fire the Spearfish Torpedoes Torpedoes can be fired at surface vessels and other submarines but they will also have 12 ballistic missile tubes that can launch the Trident D5 missiles

Each dreadn submarine will carry 8 to 12 of these nuclear missiles and ensure that the UK maintains a continuous at Sea deterrent and James do you want to explain what the continuous at Sea deterrent is the UK has had a ballistic missile submarine armed with nuclear missiles at Sea since

1969 it guarantees mutually assured destruction if another nuclear power were to fire on the UK actually I have a fun fact for you jack each Trident sub has a handwritten letter for the commanding officer from the prime minister with details of what to do in case Britain has been attacked and

There’s nobody left to give orders it’s thought that the letter could contain four options retaliate don’t retaliate use your own judgment or place the command of the submarine under us or Australian command maybe fun fact isn’t the right word given the context but it was certainly interesting each Trident

D5 missile has a range of 4,000 IAL miles and can hit a target with an accuracy to within meters and just to put that into perspective 4,000 nautical miles is 4,600 MI or about the distance between the UK and China exactly each trient D5 missile has an explosive yield of around 100

Kilotons it’s said that just one missile could wipe out a large city and each submarine will carry up to 12 missiles I wouldn’t want to be on the receiving end of that m mutually assured destruction is both extremely frightening and extremely reassuring I agree okay now let’s talk about the

Stealth capabilities that sets the Dreadnaught submarines apart from all others so like we’ve already said the purpose of these submarines is to stay completely hidden there’s only a couple of people that actually know their current location at any given time think of it like a big game of hide and seek

And the submarine service are reigning Champions 60 odd years running but how do they achieve this level of stealth submarines stay hidden underwater by being extremely silent and by reducing the reflections of active sonar sound waves remember if a submarine can’t be heard then it can’t be attacked silence is the best defense

Mechanism it’s not like an enemy submarine can just look out of a window to see where you are maybe we should explain the two types of sonar for our viewers submarines use passive sonar and active sonar to locate objects in the water passive sonar is an underwater microphone that listens for sounds like

Engines propellers or angry Russian shouting and active sonar emits pulses of sounds and listens for Echoes So to avoid passive sonar reduce the noise and to avoid active sonar reduce the reflections of sound exactly the dreadnut has made significant changes to avoid both types of sonar detection these changes have been so effective

That there was talk that the US was angry with the UK for not sharing these secrets with them it’s not like the US to be behind the curve when it comes to military Tech is it Jack it isn’t why didn’t you share your secrets with us

James we’ve got to keep some things for ourselves it’s not personal so to reduce the noise there’s been a few changes so instead of a steam turbine driving the propulsor the dreadnots used the Rolls-Royce pw3 nuclear reactor to generate electricity which is then used to drive the the

Propulsor this is much quieter but there’s also been updates to the pump jet propulsor to make it even quieter especially at higher speeds and the entire shape is inspired by whales to reduce the drag and noise and to reduce Reflections the biggest difference is the double Hull design a double Hull

Isn’t uncommon under the water Russia and China both have submarines with a double hole design but the dread knot is different because the outer layer is thin and shaped to deflect active sonar whereas the outer layer on other submarines is intended to act as an extra layer of protection against

Torpedoes the dreadnots outer layer is shaped with sloping sides extending down the full length of the hall so it’s much better at deflecting active sonar than other submarine designs yeah the outer hole shape behaves a lot like a stealth fighter plane but this outer shell is

Also covered in anaco tiles an eoic just means without Echo and the space between the inner and outer Hull is stuffed with more an eoic material the UK is lucky to have such an incredible set of submarines entering the Royal Navy service and I’m sure it’ll be a great replacement for the

Current continuous at Sea deterrent the Vanguard class and they’ve also got a fantastic well-trained and dedicated crew that put themselves through huge strain to protect their country very well said I completely agree if you’ve enjoyed our Deep dive into the dreadn class submarines then hit the like
