Britain will create a new nuclear warhead without underground testing

Britain's nuclear forces are represented by four Vanguard nuclear submarines, which can carry up to 16 Trident II ICBMs. The missiles are supplied by the United States, but the warheads placed on them (up to 8 in one ICBM) are produced in-house.

As stated by the country's Ministry of Defense, Britain is implementing a program to replace the warhead of nuclear weapons, creating a new warhead A21/Mk7 (also known as Astraea), which will be unified with the American warhead W93/Mk7 (being developed in the USA for installation on nuclear submarines from 2034).

It will be the first British warhead developed in an era when we no longer test our weapon underground, observing our voluntary moratorium

- says the document of the Ministry of Defense.

To avoid testing, a unique technology was developed to test warheads using the football-field-sized Orion laser system, which allows one to study the physics of the extreme temperatures and pressures that occur during a nuclear explosion. At the same time, supercomputers make it possible to carry out simulations without resorting to warhead detonation. The Valiant supercomputer was recently ordered to test the design, performance and reliability of the warhead.

To replace nuclear weapons carriers, construction of Dreadnought-class submarines has been underway since 2016. The first of them is expected to enter the fleet at the beginning of 2030. A total of 4 nuclear submarines of this project will be built. The program costs £31 billion.

As indicated in the document of the military department, the renewal of the nuclear arsenal is caused by threats from a number of countries:

Russia is trying to use reckless nuclear rhetoric to prevent aid from being sent to Ukraine. China is rapidly increasing the number of warheads and expanding the range of delivery vehicles. North Korea regularly rattles its nuclear weapons. Iran produces highly enriched uranium without adequate IAEA access.

Well, all the bad and scary ones are Russia and China and Iran and the DPRK... Some Anglo-Saxons are white and fluffy, but the most innocent is Ukraine...??? When you're talking about complete heresy, the main thing is not to laugh...

[Mikhail Ivanov]

Well, it's done! Yesterday morning I wrote that before the evening the Anglo-Saxons will make another “invention”))) These figures’ new aircraft carriers cannot take part in exercises, they look for the admiral through advertisements on social networks, there are no vegetables in stores, but they invent everything!) Just like Hitler (recognized in our country as a foreign agent) at the end of his career...

[krot]

In my opinion, if the island of the Anglo-Saxons sinks to the bottom of the sea, peace will reign throughout the planet!

Without testing, will it somehow explode or not, one of the two?

We, too, are modernizing our nuclear weapons without natural testing. Oatmeal technology specialists have what they get out of it - we'll see. In any case, the filthy little island is not our competitor in this regard.

We have a lot of experience, plus we have enrichment plants and nuclear power plants. in a word, we understand something about atomic fission. Now for the good news. According to the latest Hollywood films, made in the UK, this is even worse than made in chaina 20 years ago. By the way, the quality of various Jaguars and Landrovers, as well as aircraft carriers, confirms everything. True, all sorts of BMWs bought British car factories and greatly improved the quality.

Do the British think that they have the right to tell us what weapons to fight them with? Rest assured, the cut will be used last.

[Fatalist]

Oh oh. No matter how it turns out with the new aircraft carrier. Oh, these British scientists!) And it’s the Yankees and their lawyers who are shaking the air with vigorous rhetoric. And right there in this news is the answer to the Yankees: not only the USA, Russia, China, but also France and England should sit down at the negotiating table.

We remember, we remember... ICBM tests, came out and fell next to the submarine.
No, guys, it’s better for you to do virtual tests... It’s safer... First of all, for you.

[topol717]

They are better off making virtual missiles, warheads and aircraft carriers. And then experience all this virtually.

[gmss]

You can save a couple of Sarmatians, but if something happens, they will destroy themselves or accidentally drop them on some Krakow
It's better to play around on the computer, it's safer for everyone

I wonder what a “computer test” is? Any test of nuclear weapons, only in reality, and the rest is fake and horror.

[Enceladus]

Well, thermonuclear calculations - in general, computers and simulations are quite successful - the process is statistical and probabilistic and there have been a lot of previous measurements. This is not a 3-body problem, in which we can only do less than 1% of special cases

Man, don't hesitate. You weren’t there, but let’s face it, there aren’t idiots there either.

[Enceladus]

The charge is still a macroscopic system as a whole, although it lives on weak interaction, there are fluctuations, but on a macro scale it is completely calculated

[alexoff]

About 80-70 years ago, calculations were made using adding machines and slide rules, and the loaves collected according to nuclear calculations always exploded. The only difference was how much radiation it would spread and the power, plus or minus five percent.

[Enceladus]

A rubber woman the size of a football field? Strongly!
We're just coming out of the moratorium
It would be nice if there were more warheads... that’s why the last 2 launches didn’t go well... and the last one, the Trident actually knocked out the submarine itself, tearing apart the thin (outer) hull.

[Zenn]

It would be a shame to deal with the old rocket, it doesn’t fly, but they already want a new one.

[boriz]

Why do they need a new warhead? We'll send them ours. Free, fast and more than one.

[cat-begemot]

Wanting does not mean being able. And without real tests, no modeling will show the real performance and power of the device. I’m surprised that we don’t carry out tests - firstly, it’s loud, secondly, it’s beautiful, thirdly, check it again and make sure that the bomb never works not superfluous. And most importantly, any real test is not a cartoon, it is a real statement to the enemy of presence and determination to use. Comrade Shoigu, why don’t we conduct tests anywhere - are we embarrassed or nothing? The West, as well as the East, is only respected strength, so why are we so slowly and cautiously afraid of the status of a great power. The Union would have struck more than once, and would have invited “partners” and allies to attend and watch, feel, so to speak.

The one who took the piss is the daughter-in-law! They do not notice their machinations, although they have long since earned the right to be cleared from the surface of the planet.
