Re: Astute Class Attack Submarine (SSN) (RN)
and it goes well beyond using IP.
It essentially means the system has been developed as modular from the start, and uses as little propriety tech as possible. The main interfaces between sub systems should always conform to a recognized industry standard, which can be IP, or a whole load of other industrial standards, likely it will be a mix and match of different standards depending on the application. That means when the time comes to upgrade a part, it should just plug in and play, rather than having to reverse engineer the protocol Fred invented 15 years ago.
Windows for warships is no more. BAE have their own system now, that runs in a virtual layer on top of commercial hardware. That means you can change the real hardware without worrying about your instructions not being supported by the new chip, a problem facing loads of military kit. That's the same trick Android uses to run everywhere, where as Windows is fixed to Intel.

Another Linux clone, like Android (or maybe branch is more appropriate than clone)? Interesting to note that the first commercial system that I worked on 35 years ago (NCR), used the same principle. So do the IBM systems that I currently work on (developed for custom 48-bit processors and now on 8th generation Power processors - the same code will run without recompiling on every OS release).shark bait wrote: BAE have their own system now, that runs in a virtual layer on top of commercial hardware.
On a more Astute related note - the RN has called off 4 COGS (Combined Oxygen Generator Sets) from a contract for 8, for delivery over the next 3 years. Seems to be more than the Astute build schedule requires, so maybe some re-fits in there?

Oh-boy, error messages on UKDF (not as if the screen wouldn't be dotted with them in any case ). Worked on such networks when they were "the" thing; about 10 yrs before W2000.Pymes75 wrote:Windows runs on Ethernet/IP networks

It seems it has cost £3million to repair her (or possibly that, £3million has been spent in the 2016/2017 budget, not clear if repairs are still ongoing and eating into this years budget)...Cooper wrote:When it comes to the tales of woe that have bedevilled this class of sub, no news is good news.Digger22 wrote:Any news on Ambush.

Has boat 7 been laid down yet, and is it officially confirmed that she will be called Ajax?
Many thanks

A BAE press release in March 2014 confirmed that steel had been cut for the 7th boat.

Re: Astute Class Attack Submarine (SSN) (RN)
There was a photo somewhere about how the new hall can take three Astutes, side by side... it is not clear to me how this helps with handling the bigger Dreadnoughts: fatter, longer, or both?
- or is it just that they really have to step on the gas, now, with the Astutes... to ever get on with the Dreadnoughts

Re: Astute Class Attack Submarine (SSN) (RN)
Also need to step on the gas with Astutes replacement, Astute 1 is out of service before Dreadnought 3 is in the water, there's a big gap over the horizon.

The hall appears more than large enough to accommodate what ever the navy's requirement for Dreadnought are. Very large hall indeed.ArmChairCivvy wrote:There was a photo somewhere about how the new hall can take three Astutes, side by side... it is not clear to me how this helps with handling the bigger Dreadnoughts: fatter, longer, or both?

Funny to think HMS Invincible was launched from Barrow-In-Furness in 1977.
Barrow-In-Furness bus depot is now an Aldi supermarket.

Meanwhile, HMS Astute returns to the fleet after first refit. No mention of what works were actually performed.

Re: Astute Class Attack Submarine (SSN) (RN)
Thanks, instrumented dives do not happen every day, so was fun to watch.
The predecessor was decommissioned last July so we might be on our way back to seven again:
Only three T-boats remain in the class which will be substituted by the new Astute-class submarines.
Three Astute boats are [were then, when the number of T-boats went down by one] already in service with the Royal Navy.

Re: Astute Class Attack Submarine (SSN) (RN)
Nice to see the that BAE confirmed again that work had started on boat 7. I'm a little concerned about the 7th, given that it's not yet named, and we are down to 6 SSBNs currently (in line with our nearest peer, France) and seemingly doing ok (as far as the politicians and civil servants are concerned), might it not seem like an easy target to save a billion????

Re: Astute Class Attack Submarine (SSN) (RN)
My bad! Clearly those two will be cut soon enough and we will be back down to 4!
Re: Astute Class Attack Submarine (SSN) (RN)
2 Questions, is Ambush back in service, and when will the next Trafalgar decommission?
Re: Astute Class Attack Submarine (SSN) (RN)
According to my list, the next T boat to go should be HMS Trenchant in 2019.
Re: Astute Class Attack Submarine (SSN) (RN)
What about this:
There is deepening concern that the funds for the completion of the seventh and final Astute class submarine are not available.

What's her position about heavily armed, well prepared and overmanned armies?
Oh, noone's ever heard of Fortune favoring them, sir.
According to General Tacticus, it's because they favor themselves…

Re: Astute Class Attack Submarine (SSN) (RN)
I thought that construction started on the 7th a few years ago. I suspect a lot of long lead items are already purchased. This would be crazy to cut the 7th. That would really be cutting to the bone. But i suspect if it were a hard choice between cutting the Albions or the 7th Astute it would be easier to cut the Astute. There wouldnt be as much public outrage than cutting the Amphibs plus the work force at Barrow will be safe with work overlapping with the new SSBN’s.
