The fourth British atomic submarine of the Astyut class sailed for the first time

The fourth nuclear submarine, Audacious, of the Astute project, built in the interests of the British Navy, left the BAE Systems shipyard in Barrow-in-Furness and headed for the Clyde Naval Base. This is reported by British media.

This is the first entry into the sea of ​​the latest British submarine launched in May 2017. The submarine is the fourth in a series of seven submarines of the Astyut class intended for the Royal Navy of Britain. Laid in March 2009, the baptism ceremony took place on December 16, 2016. Broadcast the fleet expected in 2018.

In total, BAE Systems is to build 7 Astyut class nuclear submarines for the country's Navy. The lead submarine was handed over to the British Navy in November 2010. The second submarine of the series, Ambush, became part of the Navy on March 1, 2013. The third submarine of the series, "Artfal", was transferred to the British Navy on December 10, 2015 and became part of the fleet on March 18, 2016. Currently, at the different stages of completion there are three more nuclear submarines of this class.

In the British Navy, new submarines should replace the Trafalgar type submarines (three such nuclear submarines, put into operation from 1989 to 1991, remain in service).

Submarines of the Astyut class are designed both for operations in the fleet and in isolation from the main forces. Submarines can be used to carry out the tasks of combating enemy ships and submarines, attack ground targets, carry out the landing of groups of combat swimmers and gather intelligence information.

The displacement of the Astyut class submarine is 7400 tons, the hull length is 97 meters. Speed ​​under water - up to 29 knots. The working depth is 300 meters.

Rolls-Royce PWR-2 Nuclear Reactor Not Requiring Reboot. The service life is 25 years. Two turbines manufactured by Elstom (former General Electric) were installed. This power plant provides the rotation of one shaft and the operation of the jet propulsion. In addition, on board the submarines of this class there are two auxiliary diesel engines, as well as an emergency propulsion engine that rotates the retractable auxiliary propulsion.

Armament - six 533-mm torpedo tubes, as well as Tomahawk cruise missiles and Harpoon anti-ship missiles.

And in Russia, how many new nuclear submarines went into operation since the late 90s?

Multipurpose - 1 Project 885

[Sky strike fighter]

Kazan of the 885M project is undergoing state tests. Another 885M in the coming year will be commissioned in Novosibirsk, in my opinion (I can be mistaken), already launched and completed. In the 90s, they built a series of multipurpose submarines of the Schuka-B class (from 8 submarines) . Belgorod project 09852 is being completed. This submarine is bigger than Borea. Well, 4 Boreas, 3 of which have already joined the fleet.

[Doccor18]

The question has been since the late 90s ...
971 projects in 1993 stopped building. Nerpa and the Boar are the last representatives. Cheetah really was lowered in 2001. For a long time he was tormented by the poor fellow on the slipways. And the 885M is being built and descended, you are right, but not yet in the Navy.

[Sky strike fighter]

The same Cheetah on an improved project began to be built in late 1991.
Project 971 boats received the code name "Akula" in NATO countries. Later, the project was improved several times, and the boats built according to the modified projects received the code name “Improved Akula” in the West (Rus. “Improved Shark”), project 971M corresponds to the designation “Akula-II”. The last of the built boats, K-335 "Cheetah", the embodiment of the latest technological advances, is called "Akula-III" in the West.

And someone here tryndit due to a shift to the right. Look at the timing - not everything is so bad in our country.

I am interested in the fate of three unfinished buildings. It seems to me that Britain, and now is not up to the fleet, but further, there will be more.

[voyaka uh]

Many projects will stop for a year or two. Not only in England.
Then unwind again.

Nice boat. Although it looks angular. But I read how they wiped their nose on the teachings of the Americans on the Virgin in the teachings. Two times finding her, and conditionally drowning

[Connor MacLeod]

Well, why are there as many as 9 ash trees (with a displacement of 13000 tons)? They would build 6 ash trees to replace the loaves, and 6 huskies (6000-7000 tons each) with the funds released. And then another 6 huskies somehow scratched. And diesels need more ...

06 × 885
12 × 545
24×677+877

Something like this ...

[Sky strike fighter]

545 project of the 5th generation submarine is Husky, she is Laika.
955 Borey. The Warsaw is 636.3. A 877 Halibut.

[Connor MacLeod]

Well, I wrote like that:

6 ash trees (Project 885)
12 huskies (Project 545)
24 frets and Warsaw (pr. 677 and ... well, yes jamb 636 and not 877)

[Sky strike fighter]

So the 545 project will eventually have to replace Yasen-M (885M). Or do you want to produce them at the same time? Besides, the 545 will not be soon. By the way, you forgot about the submarines of the 955 project and the submarines.

[Connor MacLeod]

Yes, it is advisable that the Fleet have at the same time submarines carrying RCCs to neutralize enemy AUGs and KUGs as a replacement for 949 projects (there are already 13000 tons of Ash-tree, so everything is fine here), and besides this, submarines are hunters to cover Borea and Ash-tree (with a much smaller displacement of 6000-7000 tons) to replace 971 projects. Likes or non-likes call whatever you want ...

[Sky strike fighter]

So projects 971 and 949 radically modernize, restart the reactors, so that they will last for more than a decade. Problems with the introduction of MAPLs were due to too radical modernization of the above projects and the complexity of the 885M project, a lot of new ones. Like, this is a distant prospect.

Does she launch missiles from TA? If there are mines, then how many of them? Explain, please.

If you ask about Ash-M, then she has torpedo tubes for launching torpedoes, Case, as well as 8 modules, each of which contains 4 Onyx anti-ship missiles / 4 Zircon / 5 anti-ship missiles Caliber.

The Yasenei arsenal includes 30 USET-80 homing electric torpedoes with the possibility of replacing them with the promising Fizik and Case ammunition.
The main weapon of the submarine - vertical launchers for the Onyx and Caliber cruise anti-ship missiles - is located closer to the stern. The Ash can shoot missiles both from the surface and from under the water. Eight modules can accommodate 32 Onyx or 40 more compact Calibers. An arsenal of missiles with different characteristics: the supersonic Onyx and the long-range Caliber, gives the ship's crew more opportunities to perform a combat mission.

If your question is with Astyut, then everything starts from torpedo tubes.

The armament of the Estuary nuclear submarine: six 533-mm torpedo tubes, from which it is also possible to shoot UGM-109 Tomahawk cruise missiles and UGM-84D-2 Harpoon anti-ship missiles. The range of the Tomahawk missile of this modification is 1 km, the weight of the warhead is 600 kg.

Armament: 6 mm torpedo tubes (ammunition - UGM-533 Tomahawk cruise missiles, UGM-109D-84 Harpoon, Speafish torpedoes or mines - only 2 weapons)

[Aag]

Thanks for the detailed answer.

[Connor MacLeod]

Well, why do we need this radical modernization? If there is new electronics and a new reactor, put them on a new submarine or is it so difficult to weld a new hull? There are already so many new diesel engines stamped! Why upgrade 949 if you already have 885 to perform these functions? Displacement is two times less and 30% more ammunition RCC. The beauty! In the same way, to replace the 971, you need to come up with something based on the experience of Ashen. With a displacement of 6000-7000 tons, well, a maximum of 8000 tons. Something between the middle Pike and Lira ...

[Connor MacLeod]

This is just the same zoo now - new, old and modernized boats are all mixed up. And I have everything beautifully column:

06 × 885
12 × 545
24 × 677

Only three types. And the junk is all in the wreck ...

[Sky strike fighter]

Those 885M that there will be not very many of them, build long and expensive, but here you can upgrade by installing Caliber-PL. After a radical modernization, we actually get 4-generation submarines, modernizing 949 and 971.

In the same way, to replace the 971, you need to come up with something based on the experience of Ashen. With a displacement of 6000-7000 tons, well, a maximum of 8000 tons.

Universalization. All are now building multipurpose nuclear submarines, which should perform all functions without dividing them into submarines-hunters, submarines against AUG.
Ash-M as well as Virginia, Barracuda, Astyut are a multi-purpose submarine as they say for all occasions. So if you need specialized submarines-hunters, then modernization 971 just right. Nobody will create and build specifically to replace the 971 project. The next MAPL is Husky, it’s Laika, which should become so universal that it will combine the functions of the MAPL and the SLBM carrier. Two in one. You can load anything you want into the mines the principle of Ohio submarines upgraded under the Tomahawk.

[Sky strike fighter]

Magnify Max.

You better not try to describe this Husky, there even in Malachite they don’t really know what it will be and whether it will be at all.

Of course it will. And what other alternatives for the development of the 5th generation MAPL theme do you see in addition to combining the functions of the MAPL and SSBNs? In fact, the 5th generation of submarines will be presented firstly with a universal MAPL with a combination of missile launchers / RCC / SLBMs on board and secondly with a universal diesel NPL something between Soryu and Lada projects, such a compromise between the functionality of these two projects. So I at least imagine it.

Well, if there is money and capacity, is it better to build 9 ash and 971 MAPLs (with a displacement of 949 tons) instead of 6 ash trees and deep modernization of 6 and 7000 projects?

Universalization. All are now building multipurpose nuclear submarines, which should perform all functions without dividing them into submarines-hunters, submarines against AUG.

It doesn’t matter who is building what. We have our own doctrine. Since the potential enemy is an order of magnitude superior to us in the number of surface ships, we need a separate class of submarines carrying heavy anti-ship missiles.

Ash-M as well as Virginia, Barracuda, Astyut are a multi-purpose submarine as they say for all occasions. So if you need specialized submarines-hunters, then modernization 971 just right.

Pike has a displacement of 12000 tons. What competition can it make up for modern Western submarines with half the displacement? How will such a fool cover Boreas? She herself will need to be covered!

Nobody will create and build specifically to replace the 971 project. The next MAPL is Husky, it’s Laika, which should become so universal that it will combine the functions of the MAPL and the SLBM carrier. Two in one.

Well it’s clear in general. Full star ...

[Peter is not the first]

We would like to build our ships and submarines like this, between the head and the first - three years, and then faster, and now every year they are lowered. I hope that we will reach the Soviet time of construction and forget about the shifts, both in terms of production capabilities and financing. And let the British "Astyut", like the rest of their boats, be accompanied by constant problems during operation.

A witty approach to the name, everything with the letter "A", we are waiting, sir, when the "Anus" shaves will demonstrate, in front of the amazed world community!
