Anyone got any idea what the point is for such a weapon?ArmChairCivvy wrote:The Poseidon [rumoured to be in service by 2027; don't expect photos] weapon is unique.

Rather a second strike weapon that would leave six most important areas on (one or the other) US coast uninhabitable for a good while.Scimitar54 wrote:Starting WW3?

Is this sub going to replace the "Typhoon" class SSBN ? think they were designed to lurk about then fire thier ICBM a few months after WW3?

Thought the idea was to kill the rest of the population after they emerged from their bunkers after a few months ? but i could be wrong...

There is more on this special submarine that indicates it will deploy in 2021 with special abilities for spying very deep there is certainly the suggestion that undersea communications are very vulnerable to this

Re: Astute Class Attack Submarine (SSN) (RN)
Still about the broader context for Poseidon (because in isolation the idea sounds crazy):
In March 2018 Putin said "“During all these years since the unilateral US withdrawal from the ABM Treaty, we have been working intensively on advanced equipment and arms, which allowed us to make a breakthrough in developing new models of strategic weapons.”
+
“Nobody really wanted to talk to us about the core of the problem, and nobody wanted to listen to us. So listen now.”
And the next year the "2019 US Missile Defense Review [confirmed that thinking]: “Missile defenses provide U.S. leaders a position of strength from which to engage"
Hence, second strike has become the leading thought
- if 6 of those (Poseidons) are dropped under the Arctic ice cap, a huge number of SSNs would be needed to hunt them all down, before they head off for their target areas (not before 2027 though; dropped nor head anywhere)

Re: Astute Class Attack Submarine (SSN) (RN)
Its interesting that one of these special weapons or abilities is the ability to deploy a small nuclear-powered sensor array on the sea bed
this article suggests that Russia has invested heavily in the capability to disrupt internet cables

Re: Astute Class Attack Submarine (SSN) (RN)
I said WW3, not Armageddon. A limited (and in theory, more survivable) WW3 is the sort of Scenario that you have described. There is no need for it as a second strike weapon, as your “likely targets would in all likelihood have been destroyed already. More likely use is for a Military Target either in Port or at Sea. It is a Torpedo after all!

Re: Astute Class Attack Submarine (SSN) (RN)
Err, second strike means, primarily, not a second wave, but the capability to strike back even if your primary strike (ICBMs, for simplicity) weapons have A. been taken out in their silos, or B. - more likely - neutralised by ABM defences.Scimitar54 wrote: There is no need for it as a second strike weapon, as your “likely targets would in all likelihood have been destroyed already.
So, the first strike (whether you are the aggressor, or responding) has by now come to nothing.
Enter: Second strike (which is a capability, typically by different means... now those means have/ will soon have been stretched almost by as much as a "stretch of imagination".
Also, if you looked into the sources listed above, you may have missed the three zeros, added to the yield of the one dropped to Hiroshima
... so a torp to strike a 'seaboard' - not just a port. Actually, at 6 points.

Re: Astute Class Attack Submarine (SSN) (RN)
It was not though designed just for a unique nuclear strike capability but also for interference with undersea cables ,
This article suggests that though there may be conventions against the severing of cables there dont appear to be against the hacking of such , as to what lengths nations should go to physically stop a submarine doing this in peacetime even if the capability did exist is an interesting question ,does an Astute class vessel have options?

Re: Astute Class Attack Submarine (SSN) (RN)
Who knows but we did fit some interesting kit to one of our Swiftsure Class SSNs during the Cold War to go after an undersea cable up north that was used by the Russian Navy for communications or something like that.

Re: Astute Class Attack Submarine (SSN) (RN)
The (new) sub is making headlines as we would need umpteen Astutes for an effective counter - and therefore it will be a formidable capability.
But the similar capability (especially as for the threat to underwater cables) is much wider; Barentssobserver has put together a summary:
" Main Directorate for Deep Sea Research, the top secret unit directly subordinated the General Staff of the Russian Armed Forces; New weapons
Russia has over several years actively expanded its fleet of special purpose vessels. Several of them are built for seabed operations possibly including sabotage operations against underwater cables.
The “Akademik Aleksandrov” and its sister vessels [2 + 1 more under construction] are believed to be able to carry small-scale submarines for special operations. As reported by defense analyst H.I. Sutton, they are also believed to be involved in testing of new weapons, including the Poseidon underwater nuclear drone.[meaning that they can transport and lower them into water... not very stealthy though]
The Main Directorate for Deep Sea Research, nicknamed GUGI,[...] manages a fleet of nine nuclear-powered submarines and several more surface vessels.
Among the Directorate’s submarines are the “Podmoskovye” and the “Belgorod”.[the former old, and without some of the capabilities now being added]

Re: Astute Class Attack Submarine (SSN) (RN)
The second strike thing's already been covered, but there's probably not a lot of room for a limited nuclear exchange because it very quickly and easily becomes a matter of use 'em or lose 'em, at least as far as wo legs of the triad are concerned. I'd love to think that cooler heads would prevail, but I wouldn't want to bet a fiver on it never mind my life.Scimitar54 wrote:I said WW3, not Armageddon.

That's why I think it was a pity that INF was lost> I think Putin's quiet acquiescence was there, to get China under that umbrella... and then anti-proliferation could have gained its feet back.Pseudo wrote: not a lot of room for a limited nuclear exchange because it very quickly and easily becomes a matter of use 'em or lose 'em
But far too much of China's capability had been invested in that category, and Mr. Xi said (?) no.
- so, here we go
- which means that the thing that dragged on for the whole length of a Parliament, with the LibDems, that cruise missiles and last resort could not be mixed... because of the danger of a ... dangerous mix-up, and over-retaliation.
Well, we are well down that path now.
Hence the next 'Astutes' will have the Virginia 'payload module'.
- oh yeah, and by when are we going to get the next Astutes?

From there on, may be we should consider a mix of underwater assets? An ASPI link, posted by @seaspear sets some financial parameters:Defiance wrote:Agamemnon and Agincourt expected to be delivered by the end of 2025
"the US Navy’s contract with Boeing for five Orca XLUUVs is about $300 million with entry into service by 2022.
For a fleet of 24 Orcas in RAN service to supplement both the six Collins and 12 Attack-class submarines would be approximately $1.5bn — a little over the quarter of the cost of just one Attack-class submarine."

Re: Astute Class Attack Submarine (SSN) (RN)
I know, but nothing has been stated about the end goal. However for once we have a bigger one to play with as the ORCAs will be smaller, reportedly will be about 15[?] metres long, with a 6500 nautical-mile range.
- a very respectable range, so for ops in the N. Atlantic may be shore launched - just making assumptions based on what seems to be possible
- but howabout elsewhere? Which of our ships will be turned into a 'submarine tenders'?
