Astute Class Attack Submarine (SSN) (RN)
Re: Astute Class Attack Submarine (SSN) (RN)
Not that I am aware of. It is more a hanger that can be flooded.

If only there was a Haynes manual that could answer such questions.

Only £6. I'm sure mine cost more than that!

Quite a clever idea those M-class submarines. Getting round the slow running speeds of period torpedos by firing a supersonic, sea skimming 12” missile from a virtually submerged position before scooting silently away. Unfortunately the technology to do that in a practicable fashion was still over 50 years away.ArmChairCivvy wrote:Why waste the space... when you can have a big gun:

Same goes for the K-class submarines (submersible destroyers would be a far better description of role). Steam turbine propulsion in a submarine is a grand idea, providing you have a nuclear reactor and not oil fired boilers. You’ve got to admire the shear audacity of the attempt though.

Re: Astute Class Attack Submarine (SSN) (RN)
Now that the remaining three Vanguard class SSBN have been found not to need a record for their reactors, will this not, as a consequence mean that there is the potential for the building of another PWR2 reactor or two?
Astute boats 8 and 9 might now be at least theoretically possible.

Re: Astute Class Attack Submarine (SSN) (RN)
News about going ahead with boat 7 and the reactor core delay against boat construction plans (Dreadnoughts incl.) being cut from 51 to 8 months obviously have a connection, butScimitar54 wrote: potential for the building of another PWR2 reactor or two?

- were released in reversed order
- with a good delay inserted in between
We might end up building Astutes (with Virginia "payload" module behind the conning tower?) after the Dreadnoughts, anyway, as the couple of billion for starting the A successor design were shunted to the right in the latest EPP.
- to the right, as far as past the 10 years
- which does not mean that it is not planned, just not funded (and no political commitment, the reversing of which might be pre-empted by being "politically" costly)

Re: Astute Class Attack Submarine (SSN) (RN)
Why would Barrow revert to building Astute's after the Dreadnoughts? It will be a 40 year old design by then, with a reactor well out of production, and the PWR-3 wont fit.
Better off building a Dreadnought lite with the Virginia payload module instead of Trident.

I thought the new launchers on the dreadnoughts where design to be flexible in the terms that they can launch trident missiles or a multitude of others ?shark bait wrote:Why would Barrow revert to building Astute's after the Dreadnoughts?

Re: Astute Class Attack Submarine (SSN) (RN)
That's correct, the idea is to put different paylaod's inside the trident tubes, but I think its only and idea at the moment.
Personally I would be weary of increasing the number of trident 'capable' boats, that's why I suggested the Virginia payload module in place of the common missile compartment. (I bet its also cheaper)

Re: Astute Class Attack Submarine (SSN) (RN)
If you look for the reason on pp.22-23 of the 2018 EPP (Navy Command) you can't find it. But if you read through the separate NAO report, there is e.g. this:shark bait wrote:Why would Barrow revert to building Astute's after the Dreadnoughts?
" In response to affordability
challenges within the Equipment Plan, the Department took a number of measures
to make savings. These included delaying by two years its programme to introduce
new remotely piloted aircraft (Protector), resulting in an estimated £160 million cost
increase, and delaying some Typhoon training by one year, which increased costs
by £6 million. We have also reported on how the Department delayed by two years
the development of a replacement for the Astute-class submarine. This enabled
it to remove £1.2 billion of costs"
Quite a 'fatso' that would be, for hunter-killer duties? Even reactor designs should - ideally - be different for the silent cruising of boomers and the high speeds and spurts required - at times -of the SSNs.shark bait wrote:Better off building a Dreadnought lite

Got to be good news :

Now just need to do the same with the T26 programme

Re: Astute Class Attack Submarine (SSN) (RN)
The actual story is behind paywall, but this is all indirect bonus from the reactor/ refuelling pipeline getting sorted, the delay in months (against the original plan, which was predicated on the sub building rate) has been cut by 5/6ths.Poiuytrewq wrote:Got to be good news :
- so now that the "sub project plan" holds water again,

Over and over again (over the years, not just on these pages) I have said that SSN availability is the biggest (naval) weakness we currently have. So it is good news that improvement is in sight; can the year-long delay between a "T" going out and an "A" coming in be eliminated? Perhaps the article knows about that...

Re: Astute Class Attack Submarine (SSN) (RN)
I really wish we could push back the Dreadnought programme to allow an eighth Astute to be built as most experts believe that is the minimum number we need, but I also wish I could win the lottery this Wednesday or Saturday.

Personally I would rather spend the £1.5bn+ that would require on getting an RN SSK programme off the ground.Lord Jim wrote:I really wish we could push back the Dreadnought programme to allow an eighth Astute to be built as most experts believe that is the minimum number we need, but I also wish I could win the lottery this Wednesday or Saturday.
Don't get me wrong, I wouldn't complain if we ended up with an 8th Astute
Re: Astute Class Attack Submarine (SSN) (RN)
If conventional propulsion technologies keep evolving as fast as they are nowadays I can see a future generation of SSKs competing with SSNs in many roles and making them a cheaper and viable alternative in many ways. Sure it will be some ways off but I think they will get there.
Re: Astute Class Attack Submarine (SSN) (RN)
Might be a good idea for shorter patrols like the med & maybe for rookies to get experience of patrols....

Interesting article on the future Astute replacement.

Re: Astute Class Attack Submarine (SSN) (RN)
The article spells out the two year delay recently introduced, and also the current level of activity "The MUFC program emerged out of the Future Attack SubMarine program of the early 2000s (FASM). MUFC has moved into the initial Concept Phase in 2018 and is spending about £20 million in 2018-19, a fraction of the budget for other submarine programs."Poiuytrewq wrote:the future Astute replacement
- however that 2-yr delay was about £ 2bn, towards the tail end of the 10-yr EP
- and bumping it over the horizon (or the Marianas Trench?) helped towards balancing the overall EP... optics-wise. More likely: making the SSN availability an issue for the 40's and 50's (just like it is today)

Re: Astute Class Attack Submarine (SSN) (RN)
Fully expect it to be a Dreadnought with the trident tubes removed, anything else will be too expensive.
It's the timeline that worries me, better hope Astute has an easy life because the replacement is coming later than designed.

Re: Astute Class Attack Submarine (SSN) (RN)
The boats are built around the reactor, assuming the reactor is the same they will be roughly the same width. The V boats are not much wider than the Astute for example.

Personally, I hope the Virginia Payload Module features in any new design
