The @RoyalNavy aircraft carrier @HMSQNLZ has a problem with one of her propeller shafts.
Okay, time for another little "let's unpack this" #thread🧵
As with the @HMSPWLS in thread in 2022, to get the statement of the bleeding obvious out of the way, yep, this is not a good thing

Well, from the sounds of it, on 2nd February during pre-deployment checks, divers discovered excessive corrosion on one of the couplings on the starboard propeller shaft, *NOT* a misalignment, as was the case with @HMSPWLS in August 2022.

Report by @malnick in @Telegraph that the @RoyalNavy's frigates & destroyers lack anything beyond their 4.5in main gun to strike targets ashore for operations against the Houthis.
Okay, to the usual lack of popular demand😉, time for another little "let's unpack this" #thread🧵
Royal Navy Type 23 frigate HMS Iron Duke firing her 4.5 in gun in April 2016. This should not come as a particular surprise.
Due to budgetary constraints, the @RoyalNavy's Type 45 destroyers were famously designed "for, but not with" 16 @LockheedMartin strike-length Mk 41 Vertical Launch System cells, between the 4.5in gun & the Sylver A50 VLS for Aster.

Okay, @rich_scott2 @navalnewscom reports that @RoyalMarines Col Phil Kelly has been talking about "Project Ark Royal" the @RoyalNavy's study into catapults & arrester gear for uncrewed aircraft aboard @HMSQNLZ & @HMSPWLS.
So, time for another little "let's unpack this" #thread 🧵 Now, personally I am a fully paid-up member of the evil "Cats & Trap Mafia", who will automatically tell you the best military option was to put cats & traps on both @HMSQNLZ & @HMSPWLS & purchase two, full air groups of strike fighters, AEW aircraft, COD aircraft & helicopters.

1) Interesting catch from @larisamlbrown on reports of plans to reduce the @BritishArmy's current presence in Estonia, which was doubled after Russia invaded #Ukraine in February, back to its pre-war level of a single battlegroup, at the end of the year. 2) Inevitably, there's been some disquiet about them, with comments such as:
"many European nations [believe] that the “British army is now too small and doesn’t have enough soldiers to spare”
& "Getting troops out when Putin threatens to wipe half of Europe sends a bad message" The British Army's 1st Battalion The Royal Welsh in Estonia

Just a guess, but I reckon with the amphibious Littoral Response Group (North) in the Mediterranean on Op #Achillean, @HMSTrent & her @42_commando @RoyalMarines team will probably be heading for the Gulf of Guinea for a bit of anti-piracy work? While, of course, on the other side of the World, the @RoyalNavy's @OverseasPatrol remains busy, with @HMS_Tamar recently enforcing sanctions off Korea.

Obviously a lot more rumour that hard fact out there at the moment, but a few, preliminary thoughts on reports that @HMSPWLS' has a problem with one of her propeller shafts:
1) Yep, this is not a good thing (just to get the statement of the bleeding obvious out of the way). 2) Yes, this does happen & to other navies too - @NavyLookout notes HMS Illustrious' gearbox fire in 1986, others have mentioned the major electrical failure aboard @USSHARRYSTRUMAN in August 2019 & there are plenty more to choose from in between. news.usni.org/2019/08/31/uss…

1) With gas supplies, storage & moves (or lack thereof) to improve both, making the news (still), it may be time for a brief (non-specialist) #thread🧵 on a couple of the #maritime aspects of it, starting with re-posting this little thread from January on where, how & from whom. 2) As mentioned in that thread, Britain already has three of Europe's largest facilities for handling Liquified Natural Gas & in March @Trafigura announced their intention to re-open the fourth at Teesport, though there seems to have been little news since gazettelive.co.uk/news/teesside-…

1) A couple of concerning effects of Europe's reducing river levels on the #UkraineWar, perhaps the most direct of which is the effects of the declining levels of the Danube on Ukraine's ability to use that river to bypass the Russian #blockade of the country's Black Sea ports. 2) See this excellent continuing #thread🧵for details of efforts to expand use of the Danube - amongst other things - to bypass Russia's #blockade, which are necessarily ongoing, despite the agreement to open safe corridors from Ukraine's Black Sea ports.

1) A little - slightly belated - #thread🧵on this great catch by @NavyLookout of the British Government's (rather low-key) announcement on 11th July that @RFAArgus "represents the optimum solution to support a forward-deployed Littoral Response Group", & some of its implications. 2) That she was under consideration for the role was announced to @CommonsDefence on 6th July, however, that it is actually to be @RFAArgus is still something of a surprise, given one of the Bay Class has been publicly earmarked for it since March 2021.

BBC News piece by @Matt_Murphy15 on the work to establish safe passages for convoys of grain ships out of Odesa, Chornomorsk & Pivdennyi, following the Turkey & @UN brokered deal, signed on 23rd July, to relieve at least this part of Russia's #blockade bbc.co.uk/news/world-eur… Work seemingly progresses apace, with the Russian delegation, under Rear Admiral Eduard Luik, arriving in Istanbul yesterday to join the new, joint grain co-ordination centre, which has apparently already opened.

1) It looks like the Russians have been trying to finally clear the wreck of their amphibious landing ship Saratov, that was sunk alongside at Berdyansk at the end of March. #UkraineWar 2) It's worth noting the upper deck & superstructure are largely gone. These were still very much in evidence after the fire/explosion caused by the Tochka-U strike, but at least one of the dockside cranes appears to have been reactivated for the purpose of demolishing the wreck.

Interesting. It does look like the Russians placed at least one, long-range artillery piece on Snake Island - a Tornado-G MLRS with a 90km range, presumably to try counter-battery fire to forestall what actually happened, though one suspects issues of aim without things like the aerially assisted direction the Ukrainians had from their TB2s, limited ammunition supply, sheer disparity in firepower against that available (& suppliable) ashore were insurmountable. Inability to find cover would almost certainly have been an issue too, though it is worth...

1) Useful #new article by @NavyLookout on the state of play with the @RFAHeadquarters, going through issues such as crewing difficulties, @RFAFortVictoria & the lack of the Fleet Solid Support replacement, the mothballing of the Wave Class & consequent strain on the Tide Class. 2) There does, however, seem to be a rather concerning issue highlighted in the passage on the Bay Class amphibious landing ships, relating to the date at which the conversion work to @RFALymeBay for her to operate at the heart of Littoral Response Group (South) will be completed

The paddle steamer Gracie Fields had been taken up into @RoyalNavy service at the start of #WW2 as a minesweeper & was bombed off La Panne on this day 1940, sinking the following morning. She became synonymous with the #Dunkirk evacuation thanks to JB Priestly's BBC broadcast.

The @RFAHeadquarters is absolutely vital for the @RoyalNavy's carrier strike group, allowing it to operate for long periods at sea, not only supplying it with fuel from Tide Class tankers like @RFATidespring, but also ammunition & other solid stores from @RFAFortVictoria. ImageImage With @RFAFortVictoria now a unique vessel after the scrapping of her sister ship RFA Fort George, back in 2011-2013 it is, of course, vital that the much delayed Fleet Solid Support ship replacements are constructed A.S.A.P. in order to keep this going.

1) @Reuters report that Deputy Foreign Minister Andrei Rudenko has apparently suggested Russia is ready to provide a humanitarian corridor for vessels carrying food to leave Ukrainian ports, in return for the lifting of some sanctions #blockade #UkraineWar reuters.com/world/europe/r… 2) This is not the first such offer made by Russia. @SamChambers of @splash_247 reported another in March, which resulted in no ships sailing, & a different result this time would be a considerable surprise. splash247.com/no-sign-shippi…

Interesting @ForeignPolicy piece by Emily Ferris of @ISS_RUSI looking at Russia's reliance on & troubles with rail transport in its #UkraineWar
However, it's worth bearing in mind, particularly amid further talk about Odesa & Mykolaiv, that Russia also has a port opening problem. Probably the first port Russian forces took in the first days of the #UkraineWar was Berdyansk. The first ships to enter arrived in the middle of March & around ten days later they appeared to have cleared just two berths, whereupon the Saratov was sunk.

The @USNavy aircraft carrier @USSHARRYSTRUMAN pulling into Trieste in Italy marks something of a lull what has been a huge amount of naval activity to reinforce & reassure @NATO allies since the start of the #UkraineWar After her 65 day #Clemenceau22 deployment (much of which was spent in company with @USSHARRYSTRUMAN & the @ItalianNavy aircraft carrier Cavour), @MarineNationale's @French_CSG returned to Toulon on 7th April 2022
