Sukellusveneet

[JR49]

Onkohan tätä linkattu vielä foorumille?
Ehkä ei koska tiedustelusukellusveneet on hys-hys ja Ranskan teollisuudesta ei nykyään puhuta kuin hävittäjistä ja maihinnousutukialuksista.
Siis http://www.hisutton.com/DGSE_SDVs.html joka kertoo DGSE:n salaisista minisukellusveneistä.

Kiinnostava. Erityisesti kannattaa vierittää sivun loppuun, josta on linkki Naval Spetznaz -osuuteen.

Palanen historiaa 100 vuoden takaa. Ajettiin ohi kesällä josta pari huonoa videokaappausta. Toisessa Suursaari lännen puolelta ja toisessa Hamnskär pohjoisesta, muistomerkki näkyy saaren oikealla reunalla kalliolla. Täytyy ensi kesänä ajaa UC 57:n reitti ja rantautua Hamnskäriin, 100-vuotisen tapahtuman kunniaksi

Russian Project 949A Antey submarines will be armed with Kalibr missile systems following an upgrade project, according to state media reports.

The vessels, also known by their NATO reporting names Oscar I and Oscar II, are currently armed with P-700 Granit cruise missiles in addition to various anti-ship and anti-submarine weapons. The Kremlin's plans to improve the Soviet-era ships were announced by Russian Deputy Defense Minister Yuri Borisov.

"The Zvezda shipyard is carrying out profound modernization of Project 949A nuclear submarines, including the replacement of armament with the Kalibr missile complex and also the replacement of navigation, life support and other systems," the minister told the TASS news agency.

Moscow has so far constructed 11 Project 949A Antey submarines, 8 of which have remained operational with the country's navy. Each vessel displaces 24,000 tons at sea.

Russia's Rubin Central Design Bureau for Marine Engineering CEO Igor Vilnit adds all Project 949A Antey submarines will receive the upgrade.

Kawasaki delivers Japan's eighth Souryu-class submarine

Funding for a 12th boat was approved under Japan's fiscal year 2016 budget, and the country is expected to operate a fleet of 12 Souryu-class submarines by 2021.

Japani jatkaa varustautumistaan poissa suurista otsikoista. Hyvä vain, Kiina täytyy pitää saarroksissa voimakkailla armeijoilla. Vielä kun Etelä-Korea, Taiwan ja Japani ymmärtäisivät unohtaa kiistansa yhteisen uhkan edessä.

Miksi tuohon egyptin veneen rantautumis operaatioon tarvittiin joukkoeellinen päälikköjä?

Miksi tuohon egyptin veneen rantautumis operaatioon tarvittiin joukkoeellinen päälikköjä?

Halusivat varmaan varmistaa, että 450 mlijoonan euron vene rantautuu oikein, eivätkä seilorit runttaa sitä laituria vasten tai jotain. Arabiupseerien luottamus alaisiinsa ei taida olla kovin korkea, mikä näkyy tuossa alemassa videossa siten että koppalakit pyörivät ympäriinsä ja heiluttelevat käsiään osoitellen kuka minnekkin.

En ymmärrä miksi he eivät rakenna erikseen niille U muotoista laituria mihin suve voi ajaa suoraan siivekkeitä vaurioittamatta. Mutta jokin luottamus pitää alaisiin olla notta homma pyörii eikä mene reisille kusten.

"The NATO Science and Technology Organization’s Centre for Maritime Research and Experimentation (CMRE, see below for more info) has developed a standard for underwater acoustic communications called JANUS, which is recognised as a NATO standard by all NATO Allies since 24 March 2017. This marks the first time that a digital underwater communication protocol has been acknowledged at international level and opens the way to develop many exciting underwater communication applications."

The Fathom, made by Reynolds Marion, is a speedboat that transforms into a submarine.

http://www.foxnews.com/tech/2017/04...ts-and-hypersubs-to-storm-future-beaches.html

Marion calls the hybrid Fathom, a “HyperSub.” A specific model was created and brought to this exercise with details rather hush hush. But in general, the HyperSub can deploy from a beach or a dock and with its two 480-hp Yanmar 6LY3-ETP diesel engines reach cruising speeds of 38 mph.

To evade enemy detection, it could dive beneath the surface. Able to recharge dive air and batteries, the vehicle can dive repeatedly. It is designed to provide protection from pressure changes.

The HyperSub has more than 30,000 pounds of lift on demand. When the “coast is clear,” the Fathom can surface again and zip along the shore conducting surveillance.

The dry chamber, where the vehicle is driven and personnel sit, can be customized.

Another hybrid that the Navy and Marine Corps has been testing in this exercise is the solar and wind powered Submaran. This innovation is part sailboat and part submarine.

Boffins at NATO have managed to ratify, across the entire alliance, the first ever official standard for underwater digital communications.

“This marks the first time that a digital underwater communication protocol has been acknowledged at international level and opens the way to develop many exciting underwater communication applications,” said the alliance in a statement.

NATO’s Centre for Maritime Research and Experimentation (CMRE) had the new standard, called JANUS, ratified by all of the alliance’s 28 members in late March.

http://www.theregister.co.uk/2017/04/27/nato_janus_adoption_underwater_comms/

JANUS is mainly focused on allowing underwater drones to communicate with mother ships and each other. "Robots can behave intelligently and act as a team," said João Alves, a principal scientist and project leader at CMRE. “For example, one of the robots could find some interesting feature and call the rest of the team.”

“This is particularly important for search-and-rescue operations,” added John Potter, a scientist at the CMRE Strategic Development Office and one of the authors of the 2014 paper. “Autonomous vehicles are relatively inexpensive and of course unmanned, so they can be sent to do dirty, dangerous jobs.”

Janus was the two-faced Roman sentry god who stood watch over doorways and portals. “That’s why it is called JANUS,” said Potter, “because this language opens the portal between two domains, two different operating paradigms, through which they can talk.”

The Portuguese Navy has been working with NATO on perfecting JANUS, particularly for data exchange with submarines. For typical data movement activities, submerged submarines can either receive very low frequency (VLF) broadcasts from shore stations (but cannot transmit without surfacing) or must surface for two-way communications with nearby ships.

NATO hopes that JANUS will be adopted by the civilian maritime industry as well as navies, as the paper makes clear. The alliance’s press statement gives use-case examples of scuba divers approaching the surface and needing to be aware of nearby ships and boats, or underwater survey drones communicating with oil rigs in real time. It also suggests the standard could be used “for harbour protection, maritime surveillance, mine detection, surveying offshore wind farms and pipelines, or even underwater archaeology.”

Hyvä podcast suven historiasta

Submarines are an accepted part of a strong navy and the cornerstone vessel of a superpower. But these stealth killers of the ocean were once as derided and feared as the drone is now.

This week on War College, former journalist and current naval historian Iain Ballantyne takes us through the history of the submarine. From the American Revolutionary War to the modern age of the nuclear triad, few weapons have been as controversial and as feared as the submarine. Find out why on this week’s episode.

A group of anti-nuclear campaigners have claimed Britain’s nuclear deterrent submarines are vulnerable to hackers – and their report setting out the “evidence” quotes, in part, from Wikipedia.

The British American Security Information Council (BASIC) reckoned that Blighty’s four Vanguard-class nuclear missile submarines could be hacked using one of the variety of techniques that have sprung up over the last few years.

“Recent suggestions that the fleet is vulnerable have sometimes been met with complacency and claims that the isolated ‘air-gapped’ systems cannot be penetrated,” said the report (PDF, 38 pages), which was co-authored by Russian security researcher Stanislav Abalmov and veteran British anti-nuke campaigner Paul Ingram, BASIC’s exec director.

The report sets out the usual generic attack vectors and the factors that mitigate these – chiefly, the fact that for months at a time the boat is air-gapped from the entire outside world by virtue of being hundreds of feet below the sea’s surface.

http://www.theregister.co.uk/2017/06/01/trident_nuclear_deterrent_submarines_hackable_lol_no/

Of most interest is its chapter on onboard networks. All British submarines run BAE Systems’ Submarine Command System (SMCS) and have done for more than a decade. As the name implies, SMCS is used to navigate the boat and integrate tactical data from her sonar, hydrophones, radar, and so on. The report also claims that SMCS is “based upon a version of Windows XP [that is] known colloquially as ‘Windows for Warships’,” which seems to be based on a Register article written back in 2008.

A leading expert told El Reg today: “It's perfectly possible to run computer weapon systems in such a way that they are hard or impossible to hack. This becomes a lot easier when there is no requirement for network access or rapid decision-making, as in the case of Trident. Avoiding quick decisions is the whole reason for putting nuclear missiles on submarines, and water-gapping is considerably more effective than just air-gapping. It's always possible that there are discoverable vulnerabilities in Trident maintenance and refit, but there is no reason why there must be: and the authors of this report don't have any useful or relevant knowledge of Trident maintenance, so their opinion is worth nothing.”
