The design is relatively small, in the order of 5.5m in diameter and ~50m long. The most distinctive feature is the extremely small sail. The new video shows crewmen on the casing, challenging earlier speculation that it could be a prototype very large unmanned underwater vehicle (UUV). The single-hull construction and sheer size also point to a crewed submarine.
 
Storage of obsolete nuclear submarines has cost the UK taxpayer £500m because of “dismal” failings in the government’s nuclear decommissioning programme, Whitehall’s spending watchdog has found.

The Ministry of Defence has twice as many submarines in storage as it does in service and has not disposed of any of the 20 vessels decommissioned since 1980, the National Audit Office (NAO) said.

Nine of the vessels still contained radioactive fuel, it said. The failure to address the issue risked damaging the UK’s international reputation as a “responsible nuclear power”, the auditors concluded.

The damning findings will increase the pressure on the MoD over its management. An NAO report in January identified a £21bn funding gap in the department over the next decade.

Ministers could be questioned about the findings at a parliamentary debate on the continuous at-sea nuclear deterrent, which is scheduled for Wednesday.

Decommissioned submarines are being stored at Devonport in Plymouth and Rosyth in Fife while arrangements are made to safely dispose of their radioactive waste.

Seven of the submarines have been in storage for longer than they were in service with the Royal Navy. Auditors said the estimated overall cost of disposing of a submarine was £96m.

The MoD has estimated its total future liability for maintaining and disposing of the 20 stored and 10 in-service nuclear-powered submarines at £7.5bn over the next 120 years.

No submarines have been defuelled since 2004, when regulators said facilities did not meet required standards, and the process is not due to start again until 2023.

Auditors said the MoD did not have a fully developed plan to dispose of the operational Vanguard and Astute submarines or its future Dreadnought-class vessels, which have different types of nuclear reactor.

Meg Hillier, the chair of the public accounts committee, which oversees government spending, said the issues of safety and costs must be addressed: “For more than 20 years the Ministry of Defence has been promising to dismantle its out-of-service nuclear submarines and told my committee last year that it would now address this dismal lack of progress.

“It has still not disposed of any of the 20 submarines decommissioned since 1980 and does not yet know fully how to do it. The ministry needs to get a grip urgently before we run out of space to store and maintain submarines and we damage our reputation as a responsible nuclear power.”

Since April 1969 the Royal Navy has maintained a continuous at-sea presence of nuclear submarines, which house the UK’s nuclear weapons system.

The vessels being stored include the first submarines used to carry the UK’s nuclear deterrent – the Polaris boats HMS Revenge, Renown, Repulse and Resolution. Also in storage is the attack submarine HMS Conqueror, which sank the Argentine cruiser General Belgrano during the Falklands War.

Wednesday’s parliamentary debate has been scheduled to commemorate the 50th anniversary of the UK’s continuous at-sea nuclear deterrent.

John Woodcock, the independent MP for Barrow-in-Furness, who called for the debate, said the lack of a decommissioning plan was storing up problems for the future. “This lack of progress reflects and is partially caused by the country’s paralysis on finding a geological disposal site for waste nuclear material. Ministers cannot continue with their head in the sand on this important issue,” he said.

An MoD spokesman said: “The disposal of nuclear submarines is a complex and challenging undertaking. We remain committed to the safe, secure and cost-effective defuelling and dismantling of all decommissioned nuclear submarines as soon as practically possible.”

Nyt jos olisin leffa tuottaja taikka proppimestari, kävisin kiireen vilkkaan hakemassa yhden pois varastoon, ennenkuin ne menee pilalle taikka sulattoon. Varsinkin HMS Conquerin, jotta saisin autenttisen falklandin sodan propin.
 
Kalibrin kalibrointi.

Venäjän pohjoisen laivaston edistynein sukellusvene Severodvinsk, on ampunut pitkän kantaman Kalibr-risteilyohjuksia kotisatamastaan Zapadnaja Litsasta Kuolan niemimaalla, Izvestija uutisoi.

Asiasta tässä kertovan Barents Observerin mukaan satama on pohjoisen laivaston läntisin ja sijaitsee vain noin 60 kilometrin päässä Norjan rajasta. Suomen rajalle matkaa on 120 kilometriä. Kalibr-ohjuksen kantama on noin 660 kilometriä. Kyseessä on tiettävästi ensimmäinen kerta, kun venäläinen ydinsukellusvene ampuu risteilyohjuksen lähtemättä laiturista.

Tucked away in its most recent budget proposal, the U.S. Navy says that it is interested in giving its submarines the ability to launch small torpedoes. These weapons could offer added offensive firepower, as well as an all-new anti-torpedo defense interceptor capability. The mini-torpedos use a common body and future variants might also arm unmanned ships or submarines, as well as flying drones, act as naval mines, and more.

The Navy’s budget request for the 2020 Fiscal Year, which came out in February 2019, asks for more than $60 million to support the continued development of the AN/BYG-1 Submarine Payload Control System. Virtually all of the service’s existing submarines use variants of this software-driven combat control architecture to launch weapons and other payloads, via combinations of torpedo tubes, vertical launch systems, or countermeasures launchers, depending on the particular design. The Navy’s future Columbia-class ballistic missile submarines and Block IV and V Virginia-class attack boats, as well as Australia’s future Attack-class, will also use versions of this system.

Onko tuolla toisen kuvan isoimmassa miehittämättömässä eli XLUUVissa torpeedoputket? Ja alaviistoon suunnattuna

Ehkä, en tiedä varmasti, mutta orca on aika isohkon kokoinen ja XLUUV vielä isompi tuosta.

The diesel-electric Echo Voyager has a maximum speed of around nine miles per hour underwater and can dive to depths up to 11,000 feet deep. Its batteries give it range of more than 150 miles at a speed of around 3 miles per hour, before it needs to surface and use its air-breathing diesel generator to recharge.

Boeing has said that Echo Voyager could carry enough fuel to allow it to operate autonomously for up to six months at a time, covering total ranges of around 7,500 miles. With just one fuel module in its modular payload bays, it would still have a full range of more than 6,500 miles. It has its own sonar-enabled obstacle avoidance system, as well as an inertial navigation system.

Orca may also leverage experience Huntington Ingalls gained while working on its own large unmanned undersea vehicle project, called Proteus, in cooperation with Bluefin Robotics and Battelle. Proteus is a significantly smaller vehicle, though, at around 25 feet long, and is limited capability-wise compared to Echo-Voyager

Tuon mukaan Orca on 7.62 metriä pitkä. Xluuvi on varmaan 10 - 12 metriä.

The ocean’s depths have long remained mysterious—a dark abyss where few humans go. But we still have a stake in this alien environment; scientists want to know where pockets of pollution are worst, and where earthquakes occur along the sea floor. Passive sensors can collect such data, but transmitting it in this murky environment is a challenge.

Guangjie Han at Hohai University and his colleagues have proposed a new approach for how autonomous underwater vehicles (AUVs) patrolling those depths can better collect data from these sensors. Their design was published 27 March in IEEE Transactions on Mobile Computing.

Maavoimien sukeltajat Nanuuk-Nunalivut 2019 -operaatiossa.

Suomen maavoimien sukeltajat ensimmäistä kertaa mukana Kanadan arktisessa harjoituksessa: video näyttää sukelluksen Beaufortinmeressä
Kanadan johtamassa harjoituksessa oli mukana kolme Nato-maata sekä Suomi ja Ruotsi.
Suomen maavoimien sukeltajat osallistuivat maaliskuun lopulla ensimmäistä kertaa Kanadan johtamaan kansainväliseen Nanook-Nunalivut 2019 -operaatioon. Kyseessä oli harjoitus, johon osallistui yhteensä noin 500 ihmistä.

Nanook-Nunalivut -operaatiot järjestetään Kanadan pohjoisosissa eli Yukonissa, Luoteisterritorioissa, Nunavutissa ja Labradorissa. Kanadalaiset harjoittelevat siellä arktisen alueensa puolustamista ja kylmissä oloissa toimimista. Harjoituksiin kuuluu muun muassa pohjoisissa oloissa tarvittavien selviytymistaitojen ja logistiikan opiskelu. Tänä vuonna operaation yhtenä osana oli kansainvälinen noin 50 hengen sukellusharjoitus, jossa olivat Kanadan lisäksi mukana Nato-maat Norja ja Ranska sekä Naton kumppanimaat Suomi ja Ruotsi. Sukellusharjoituksen tukikohtana oli inuittikylä Tuktoyaktuk Luoteisterritorioissa. Sukellukset tapahtuivat sen edustalla Beaufortinmeressä.

”Pääsimme mukaan osana pohjoismaista sukellustiimiä, joka oli Ruotsi-vetoinen”, kertoo ylikersantti Janne Luukinenhttps://www.hs.fi/haku/?query=janne+luukinen, joka on toinen mukana olleista suomalaissukeltajista.

Luukinen palvelee Jääkäriprikaatissa Sodankylässä sukeltaja-aliupseerina. HS tavoitti hänet puhelimitse pilkkimässä Rovajärven harjoitusalueella.

Silloin tällöin itse kukin.

Suomen puolustusvoimissa palvelee Merivoimien sukeltajien lisäksi Maavoimien sukeltajia. Maavoimien sukeltajien toiminta-aluetta ovat pääosin sisämaan vesistöt. Suuri osa heidän työstään on veteen upotettujen toisen maailmansodan aikaisten räjähteiden raivausta. Lisäksi he antavat virka-apua muille viranomaisille eli käytännössä poliisille.
 
The U.S. naval fleet of the future may one day include submarines without a sailor from bow to stern that prowl the depths of the ocean, navigating mine-infested waters to gather intelligence or even clandestinely drop explosives.

The military views autonomous vehicles as a way to accomplish missions deemed too risky, mundane or expensive for human crews. While aerial drones have largely been tasked with these types of duties for more than a decade, the Navy is now increasingly funding robotic ships and undersea drones to complement the work done by its crewed vessels.

Last month, Boeing Co. beat out rival Lockheed Martin Corp. for a $46.7-million Navy contract modification to build an Orca undersea drone. Boeing had previously won a contract to build four of the Orca drones, bringing the total contract value for the five to $274.4 million. A large chunk of work will be done at the aerospace giant’s Huntington Beach facility, and the drones are expected to be completed by 2022.

Neither Boeing nor the Navy have disclosed the size of the robot submarines, but Boeing has previously developed and tested a 51-foot-long underwater drone prototype called the Echo Voyager.

Russia launched the world’s longest submarine today, the special mission submarine Belgorod. Designed to support a variety of military missions, including the Poseidon long-range strategic nuclear torpedo, the sub is far larger than anything operated by any other naval force, including the U.S. Navy. The six hundred foot long submarine displaces more water than a World War I battleship and can dive to a depth of 1,700 feet.

The submarine was launched today, April 23rd, at the Sevmash shipyards in Russia, with Russian President Vladimir Putin reportedly watching via satellite.

Officially known as Project-09852, the submarine was originally an Oscar II-class cruise missile submarine that the Russian government ran of funds to complete. The submarine hull sat unfinished until Moscow decided to complete it as a special mission submarine.

The hull was lengthened to approximately 184 meters (604 feet) and the ship’s displacement ballooned to 30,000 tons submerged--more than fifty percent greater than the U.S. Navy’s Ohio-class ballistic missile submarines. The result of an unfinished hull the Belgorod is a one-off, and there will not be another one like it.

Tuon mukaan Orca on 7.62 metriä pitkä. Xluuvi on varmaan 10 - 12 metriä.
Tähän vielä palaten, Orca on 51 jalkaa eli n. 15 metriä pitkä. XLUUV on n. 25m kuviin perustuen, eli hieman pienempi kuin ammoinen sukellusveneemme Saukko. Arvioisin XLUUV syväykseksi 2,5m+/- 0,5m ja uppouma jossain 100 tonnin hujakoilla, eli ihan kunnon pötkö.
 
Ruotsin kohdalla on virhe. Siellä on palveluksessa tietääkseni kaksi Södermanland- ja kaksi Gotland-luokan hyökkäyssukellusvenettä. Eli ei viittä.

Ainakin Gotlandeista ollaan modaamassa vain kaksi uushankintaveneiden rinnalle. Sitä en tiedä onko yksi jo ehditty poistaa?

Edit

Ruotsin YK:lle 2017 ilmoittama vahvuus on 3 Gotlandia ja 1 Södermanland.

Viimeksi muokattu:

Kyllähän niillä on kolme västergotlandia ja kummatkin söderit rivissä kunnes A26 korvaa ne :unsure:

Edit. Aktiiviseksi ilmoitettuja Södermanland luokan sukellusveneitä ovat Södermanland ja Östergötland. Eli viisi yhteensä käytössä :)
