I know the MoD and BAe say she was 'launched', but she never actually touched the water, did she? I was under the impression that she was wheeled out of DDH, Camilla threw some champers at her, and they wheeled her back in again. Is that wrong? Because if not, I think calling the ship 'launched' and using language like 'was built' is rather premature... Trent 900 15:08, 9 June 2007 (UTC)
I read in the BBC news that the HMS Astute four months ago, they discovered some problems on their second proto type model next the advanced Swedish submarines as the Swedish have who developed the most advanced subs next to the Russians. Even though the EMS is a beautiful sub, there are some problems that are too costly to fix. It is an probably an expensive turn over to manufacture these subs as British military budget has been cut by 42% in 2008 as the UK gov't has too much money in the banks and they have been behind on gov't payments. —Preceding unsigned comment added by 151.199.40.141 ( talk) 03:47, 26 October 2008 (UTC)
I don't know a lot about sonar capabilities, but "Its sonar is so sensitive that it can detect and identify a ship setting sail from New York whilst in dock at Portsmouth" sounds way too good to be true. Where does this fact come from? DanielVonFange 13:22, 21 September 2007 (UTC)

I have a fair bit of knowledge about sonar, primarily passive. Range is dependent upon ambient noise and the thermal structure of the ocean, among other factors. Trans Atlantic range? I strenuously doubt it. LorenzoB ( talk) 23:26, 29 June 2008 (UTC)
The advanced Sonar 2076 is a fully integrated system comprising bow, flank, fin and towed arrays that can track an object the size of a bus at a distance of more than 50 miles.
see the press release: http://www.baesystems.com/Newsroom/NewsReleases/autoGen_1074119838.html it does claim "In the right conditions it can detect the QE2 leaving New York harbour from the English Channel.", while unlikely, thats the ships manufacturer talking. maybe miscommunication between BAE and Thales, who knows.

"So finally in November 2009, Astute is starting 18 months of sea trials."
Gives an indication that whilst the boat may well be commissioned in 2010, it won't be in active service until 2011. David ( talk) 18:23, 16 November 2009 (UTC)
Commissioning scheduled for 27/10/2010, which may change if she catches fire yet again. —Preceding unsigned comment added by 86.138.1.180 ( talk) 19:02, 14 May 2010 (UTC)
The article claims that Astute will carry Sub-Harpoon, but there's no citiation and all sources that I can find seem to suggest that Tomahawk will be the only missile carried, in common with other RN SSNs. Jellyfish dave ( talk) 17:40, 17 February 2010 (UTC)
I don't think you'll find any official sources talking about mines being carried either. 86.28.170.89 ( talk) 00:01, 12 March 2010 (UTC)
Royal navy site describes Sub Harpoon as being deployed upon Swiftsure and Trafalgar class- it's reasonable to assume it'll be onthe astutue too. Meeware ( talk) 17:07, 11 May 2010 (UTC)
Some disagreement over displacement. Some sources say 7,200 tonnes, some 7,400, the following give 7,800 (submerged) –
See
Royal Navy: "When fully stored HMS Astute displaces 7800 tonnes of sea water (equivalent to 65 Blue Whales or nearly 1,000 Double Decker buses);"
Defence Procurement Agency: "Dived displacement 7800 tonnes;"
BAE Systems: "7800 tonnes submerged;"
Defence iQ: "displacement of 7,800 tons submerged;"
Naval Technology: "Displacement 7,800t (dived)."

Does anyone know what all the steam from Astute is in all the news footage? I just think it would be a good addition to the article because it's not something normally seen from a nuclear sub. Mark83 ( talk) 23:34, 22 October 2010 (UTC)
Although the plume of "steam" vented all day from Astute the Navy at Kyle claimed it was indeed the exhaust products of the back-up diesel generator. They must process the exhaust gasses somehow because as I watched the plume dissipated very quickly indeed exactly like steam and did not look at all like marine diesel exhaust. The main article is wrong about the location. Astute grounded less than a mile from the Skye Bridge. In fact she was just off the Kyleakin quarry less than half a mile from the bridge on a notorious rock plateau visible at low water. Fortunately she was not beached on this rock but grounded toward the quarry/bridge side. Astute was outside the navigable channel on the wrong side of the navigational warning buoy by some considerable margin. It is highly likely that her huge underwater mass was gripped by the extremely fast and powerful tide than funnels through the Kyles. Her low speed at the time of the incident probably exacerbated the tidal effect. She lay beached for the rest of the day and as the tide dropped nearly 50% of her top secret screw (propeller) was plainly on view. —Preceding unsigned comment added by 78.148.36.38 ( talk) 20:19, 30 March 2011 (UTC)
I've reverted the edit that says "It rumoured that repairs will cost £8 million". I've done this because:
Well-referenced sources for repair costs would be useful - but this is not a good source. Shem ( talk) 15:47, 12 December 2010 (UTC)
The "Port of Southampton" extends to west of Cowes on the IoW, to south of Culver Cliff on the eastern shore of the IoW, and then north almost to the entrance to Chichester Harbour. A very large area as seen on this chart. So a vessel can be in the port of Southampton but not tied up at a berth, or even in Southampton Docks. The original picture caption was correct. Furthermore, the vessel's name is Her Majesty's Ship Astute, abbreviated to HMS Astute, not merely Astute. George.Hutchinson ( talk) 13:59, 9 April 2011 (UTC)
Shepherd media got the wrong end of the stick when Ambush and Astute were delivered yesterday. They have not finished sea trials, and they are not yet in service, but they have been delivered by BAE to the RN. The gov.uk article "Sixth Astute Class submarine keel laid" makes this distinction clear. The submarines will be declared "in service" when they are ready to deploy. Although submarines are a bit different in acceptance timelines, we had in similar confusion with the Type 45 commissioned/in service descriptions a few years ago.
