The reason for not carrying a full warload was not because there were not enough weapons but the TSC (Torpedo Storage Compartment) was used as an accommodation space. This changed when Harpoon came as that made the TSC a magazine under RN regs. So we started hot bunking. :cry:

On Astute it shouldn't be a worry most of the time, with bunks for everyone and 11 extras.
On the other hand, at some point a very careful thought will have to go into this constant improvement and expansion of crew spaces, as it is part of what makes new units bigger, heavier and more expensive than those that came before. Wonder if and how much this impacts on a programme such as the Successor SSBN.
I don't know enough to be quite critical of it, but that it has 4 less Trident tubes than Vanguard yet is slightly bigger instead of being any smaller, is something that admittedly puzzles me.
You might also know me as Liger30, from that great forum than MP.net was.

@Gabby...
Remember reading an article regarding the circumference, displacement and volume of the hull, was directly related to the size and circumference of the PWR3 reactor needed to power the successor class of SSBN's rather than anything to do with accomodation standards.
Don't forget the size of the crew would probably fall by a similar number to the Astute's SSN which if IIRC dropped from 130+ to less than 100 compared to the Trafalgar boats.
Will try and find the article and post later.

Standard crew on older SSNs was 98 IIRC. We could sail with 125 on board, being limited by air purification equipment. We nearly always sailed with the 125, made up of Part 3 trainees and other special mission riders. There is always a request to carry more than the standard crew. Many of our riders were, for some reason, fluent in Russian.

Was HMS Ambush in Gib for repairs?
The nuclear-powered submarine HMS Ambush was in Gibraltar last week for repairs, although the HQ British Forces said nothing about it.

The submarine arrived on Thursday and left last weekend after the repair had been undertaken.

We asked HQBF if they could provide details of what repairs had been undertaken, but they said: "We do not comment on submarine activity."

PANORAMA has been informed that the fact that the submarine stayed here for several days was commensurate with the importance of the repairs needed.

We are told that the repairs were connected with the sonar equipment on the submarine which required that spares be flown out from the UK in an RAF cargo aircraft.

Royal Navy's Latest Submarine To Set Sail This Summer

Image
HMS Artful, the third of the Royal Navy’s new Astute Class attack submarines will set sail for sea trials this summer.

The Defence Secretary confirmed the news as he visited the home of the UK’s submarine manufacturing industry in Cumbria today.

Artful, which will provide the Royal Navy with its most technologically advanced submarine, is currently preparing to leave the construction yard in Barrow-in-Furness for sea trials, before joining the Royal Navy fleet around the end of this year. The seven Astute Class submarines support the jobs of 3,700 workers and 400 supply companies across the UK supply chain.

Here's something you don't see every day. That's right, clear blue skies in Barrow, even in August...
The folks at BAE Systems have provided us with a few more nice images of HMS Artful leaving her birthplace for the first time to begin sea trials in the Irish Sea.

Loving the anechoic two tone look.
Also in that last photo you can really appreciate the full size of the fin.

Royal Navy Welcomes Third Astute Class Sub to Clyde

Artful, the third of the Royal Navy’s new Astute Class attack submarines has arrived at her Scottish base port from where she will carry out sea trials before entering service later this year.

The 7,400-tonne Artful left BAE Systems construction yard at Barrow-in-Furness in Cumbria several days ago before sailing to her new home at Her Majesty’s Naval Base (HMNB) Clyde. She will provide the Royal Navy with the most technologically advanced submarine Britain has ever sent to sea.

HMNB Clyde will become a home for the Royal Navy’s submarines and associated support by 2020, creating a submarine centre of specialisation.

I always find it hilarious when you get this line of "THEY SHOULDA ADMITTED RIGHT AWAY" gets dragged out.

Yes, clearly. Revealing the exact location of a vessel who's job it is to stay as secretive as possible is clearly a good idea. For all we know this coulda been a Vanguard. What do these morons think the MoD is gonna do?

This is like when everyone was whining about how the MoD shoulda revealed the weak point on the Challenger the day it got hit because "we must have transparent moralistic blame!", without ever thinking that perhaps that information shouldn't be revealed until a response has been implemented to fix it.

Not the first time this has happened of course, but could trawlers be fitted with a device that allows submarines to know of netting being deployed in that area .

Can we export it to Whales and Dolphins ?
Such devices exist. Trouble is getting the fishermen to buy them. Or the State to buy them and give them to the fishermen.

Ambush put to the test on NATO exercise
Britain’s newest operational boat, HMS Ambush, made a rare appearance on the surface of the Mediterranean for NATO’s biggest submarine exercise of the autumn.
Over 10 days, five surface ships and seven maritime patrol aircraft and helicopters pitted their wits against seven submarines – five conventional diesel boats, two nuclear – in the Ionian Sea.

Exercise Dynamic Manta 15 was billed as one of the most demanding submarine hunting workouts above, on and below the Seven Seas.

Throwing the hat into the ring on behalf of the UK was HMS Ambush, carrying out her second operational patrol since joining the Silent Service.

The MD (M Easton) of BAE Submarines explains what vertical fitting out means, and where it came from:

ME: Vertical outfitting was actually first introduced on the second Astute Class vessel – Ambush – and is a technique that was adopted from its success with Electric Boat in the US. Since then it has been refined and is used for virtually every hull section.

Vertical outfitting involves the circular sections of the submarine being turned to stand 'on end' in a vertical configuration as opposed to the traditional method of building in a ship-wise or horizontal configuration.

It enables large, heavy or unwieldy equipment to be shipped in and offers huge advantages in terms of efficiency, thousands of man hours saved, and health and safety gains.

In addition, a flexible staging system enables the outfit teams to work on a 360º face at shoulder height, as opposed to working in the horizontal mode when work faces could be at the fitter's feet or above his head. Again there are massive efficiency and health and safety gains.
Ever-lasting truths: Multi-year budgets/ planning by necessity have to address the painful questions; more often than not the Either-Or prevails over Both-And.
