Ho letto su wikipedia sulla pagina delle future LHD(*) che la Royal Australian Navy voleva anche acquistare un'altra nave identica da usare come portaerei e credo di aver capito che il progetto non è stato approvato.A che punto è ora la situazione dell'Australia per l'acquisto di una portaerei?Se gli spagnoli hanno proposto il loro progetto di LHD potremmo noi proporre un progetto del Cavour (magari ridotto)?.

Skilled Labor Shortage Plagues Australian Shipyards

 

The shipbuilding industry in Australia is facing pressure from a shortage of skilled labor and a lack of continuity in naval shipbuilding projects.

 

The industry is grappling with the problem as Australia’s first landing helicopter dock ship (LHD) was inducted into BAE Systems’ Williams-town Dockyard here Oct. 28. The hull was constructed in Navantia’s facility in Ferrol, Spain, and brought to Australia.

Lunga vita: Parliamentary Secretary for Defence – Speech to the Submarine Institute of Australia Biennial Conference

 

SUBMARINES IN OUR MARITIME STRATEGY

The combination of cutting edge technology, and an extremely adept crew, has made the Collins submarine unmatched in our region. The Collins submarine provides Australia with a leading anti-surface and anti-submarine asset possessing a marked technical advantage over any potentially hostile submarine deployed in the region.

The Collins Class submarine – with its qualities of stealth and endurance – make RAN boats:

 

primary strike and deterrence assets

important intelligence gathering, surveillance and reconnaissance platforms

delivery, support and extraction platforms for special forces

key assets in undersea and surface warfare (esp. ASW)

able to undertake sea denial missions, such as blockades (MIW)

operate in a hostile air, undersea or surface environment

complicate any potential adversary’s planning, increasing the size and capability of any force hoping to successfully attack Australia.

 

These capabilities ensure that the Collins boats can protect Australian interests offshore effectively, either alone, or as part of a coordinated Task Force.

The Future Submarines must offer Government the same capabilities.

Further, Government is resolved that the Future Submarine will have greater range, longer endurance on patrol, and expanded capabilities (i.e. communications) as compared to the current Collins Class submarine. The Future Submarine must be able to carry different mission payloads such as uninhabited underwater vehicles (UUVs).

It will require the capability to conduct strike operations against military targets, including an adversary’s operating bases, staging areas and critical military infrastructure.

Our Future Submarine will be required to achieve its goals in a much more competitive environment. The Asia-Pacific is now home to 14 nations operating modern submarines (i.e. China, Taiwan, Japan, North Korea, South Korea, Indonesia, Malaysia, Singapore, Vietnam, India, Pakistan, Russia, US and Australia). Others have signalled their intention to acquire modern submarines for the first time (i.e. Philippines and Thailand). The regional market is estimated to be worth US$44 billion between now and 2021. By 2025 the region could host as many as 150 diesel-electric boats.

This means our seas are becoming more crowded with modern submarines. These evolving military relativities mean that the Future Submarine must be significantly more advanced than our existing Collins boats.

The Future Submarine will need to be able to travel long distances and stay there to be effective. It will need to have a payload commensurate with its mission. It must provide habitability for extended periods for its crew (and to attract and retain submariners). To do these things, the Future Submarine needs to be large.

Relative to other nations that operate diesel-electric submarines, the Future Submarine must operate across exceptionally vast distances. You simply have to lay a map of Europe over Australia to gain a concept of this. A submarine designed for the Baltic, North Sea or Mediterranean environments will not be able to deliver Australia’s capability requirements in terms of range and endurance.

This is why the Collins Class is one of the largest conventional submarines in the world.

Remember, the Asia-Pacific possesses numerous critical maritime nodes – notably the Malacca Strait, Sunda Strait, and Lombok Strait– all of which are critical to the global economy. These nodes are 2,000 or even 3,000 nm from HMAS Stirling.

Jason Clare made clear yesterday the resolve of this Government to deliver the Future Submarine, and to deliver an Australian build. This resolve was seen in our most recent budget, where we committed $214 million to the Future Submarine project; money to enable design studies, modelling, and the deep analysis required for an initial pass decision.

This resolve means creating thousands of jobs, work for hundreds of Australian companies, and establishing a new Australian industry.

An indigenous industry capable of designing, developing, building and maintaining submarines able to meet our unique capability requirements would be an enormous strategic strength for our nation.

And I can’t help but suspect that in building such an industry, we would be most effectively exploiting the considerable experience Australia has acquired from the Collins submarine.

 

Submarines? Let's roll our own

 

The major piece of good news was that a number of speakers have expressed growing confidence in extending the life of the Collins-class boats until replacements are available. ``There is a consensus, from the life extension evaluation, the Collins could be put through one more duty cycle,'' Mr Davies said. ``That is effectively a life extension of eight to 10 years.''

 

 

Upgrade per i sistemi sonar Collins submarine sonar support contract awarded

 

Minister for Defence Materiel Jason Clare today announced that Thales has been awarded a $22.2 million contract to update sonar equipment for the Royal Australian Navy’s Collins Class submarines.

The contract will involve replacing obsolescent electronic components to improve reliability and help to reduce space, weight and power requirements.

Mr Clare said the majority of specialist engineering and logistics work will be performed in the Thales facility at Rydalmere, NSW.

“The sonar system on the Collins Class submarines uses acoustic signals to safely navigate and operate effectively underwater,” Mr Clare said.

“The updating of this equipment is key to ensuring our Collins Class submarines remain operationally capable and reliable.”

Thales currently holds the contract for in-service support for the Collins sonar system and is the original manufacturer of the equipment.

The Government has allocated an additional $700 million over the next four years for Collins Class submarine sustainment.

The Collins Class submarine provides maritime surveillance, maritime strike and interdiction, reconnaissance and intelligence collection capability to the Australian Defence Force.

 

Space, power and weight savings as Thales updates Australian submarine sonar systems

 

Thales Australia has signed a major contract with the Defence Materiel Organisation to deliver a significant update to the Royal Australian Navy’s submarine sonar systems.

The company will address obsolescence issues on the Collins class Scylla sonar, boosting the reliability of a system that was initially designed over a quarter of a century ago. Specifically, the project will replace existing equipment in the Scylla Signal Processing Cabinets with modern Commercial Off The Shelf (COTS) components, and also re-host the software.

Implementing the new technology will result in a system requiring less than 20% of the number of processing racks currently used, as well as significantly fewer processing boards than its predecessor. Industry-standard COTS boards will replace bespoke originals, making the system easier to maintain and providing enhanced reliability.

The resulting COTS-based system will benefit from a reduced through life cost and will deliver substantial power savings, together with a weight saving of more than a tonne. The growth potential within the new system will also provide the opportunity for the RAN to significantly enhance its sonar detection capability in the future.

Thales Australia CEO Chris Jenkins said: "The Collins Class submarines have a very capable sonar suite, but time has moved on and we are now leveraging advances in technology to deliver an important update that will treat obsolescence and result in substantial space, power and weight savings.

"We have invested over many years and built a significant level of submarine sonar expertise in Australia, starting on the Collins in the 1980s, and then leveraging this on other naval platforms. This is deep technical expertise of international standing. Having this capability in country enables us to provide these kinds of updates economically, quickly and at low risk."

The vast majority of the update work will be performed at Thales Australia’s underwater systems facility in Rydalmere, western Sydney. The update will be physically installed in the first of six submarines in 2014 following trials at sea in 2013.

 

 

Chiudo con un link al programma dei sottomarini Aussie Australia’s Submarine Program in the Dock

Australiani (e canadasi....) credo siano l'esempio lampante di come NON si gestisce una componente sottomarina....

 

Per i secondi, siamo ad oggi a 1 su 4 sottomarini in servizio (uno dei tre è fermo da anni ed ha prestato servizio per ben 2 giorni) per i primi siamo al paradosso che, oltre alle difficoltà tecniche praticamente su tutto, per parecchio (e in realtà, tuttora....) ci sono stati più sommergibili che equipaggi.

 

Che oggi si voglia RADDOPPIARE il numero, magari puntando anche al nucleare, la dice lunga sulla lungimiranza dello stato maggiore RAN.

In questo corposo report pubblicato periodicamente dall'ASPI (un think tank che segue le FFAA australiane, e in generale il contesto geostrategico asiatico)

 

http://www.aspi.org.au/publications/publication_details.aspx?ContentID=339&pubtype=3

 

si trovano notizie piuttosto interessanti sui problemi di personale della RAN, dovuti, come viene scritto in maniera dettagliata, alla cronica penuria di personale specializzato che non si riesce a reclutare, e a un turn over elevatissimo:

 

In 2010‐11, crew shortages reduced the availability of two Anzac ships.

 

A shortage of submariners has reduced the delivery of capability. Personnel shortages were

so acute that submarines were tied up or put into maintenance early. Longer than expected

maintenance periods coupled with mechanical problems further compromised the

availability of boats. However, Navy has been successful in growing the numbers of trained

submariners, and submarine platform availability is also improving.

 

Through an innovative program, the Navy multi‐crews the Armidale Class vessels, thereby

reducing the burden on sailors and their families while maintaining a high utilisation of the

assets. At present there are 21 crews spread across 14 vessels. However, media reports in

early 2012 said that fleet availability is expected to fall for the remainder of the year as a

result of heavy maintenance and crew shortages.

 

The health of the RAN minesweeping capability is under question. Training has been

interrupted by the use of two of the Huon class vessels for border patrol duties, and in

October 2011 two of the Huon class were placed into Reserve. It’s been estimated that it will

take five years to get the full fleet operational again.

 

in sostanza, hanno problemi di equipaggio su OGNI tipo di nave della flotta: e chiaramente non si capisce come possano sperare di sostenere programmi che vedono necessariamente un aumento del personale imbarcato.

HMAS Choules out of action until April 2013

 

Defence has revealed that HMAS Choules, bought from the British last year, will be out of action until April following a mechanical breakdown June 2012.

Following consultation with the transformer manufacturer, the Defence Materiel Organisation, the Defence Science and Technology Organisation, Lloyds Classification Society and the UK Ministry of Defence, the Chief of Navy has made the decision to replace the remaining four transformers on the Choules before the ship returns to sea.

As detailed in a previous ADM report, all remaining transformers have now also been inspected and similar signs of premature ageing have been identified.

This ageing is within operational limitations and at varying levels.

The total cost of the replacement is expected to be in the order of $10 million.

The replacement transformers are currently under construction.

HMAS Choules is scheduled to return to work by April 2013.

HMAS Tobruk and Australian Defence Vessel Ocean Shield will provide any humanitarian assistance or disaster relief response required by Government over that period.

Australian Sub Report Faults Logistical Support http://www.defensenews.com/article/20121222/DEFREG03/312220002/Australian-Sub-Report-Faults-Logistical-Support?odyssey=tab|topnews|text|FRONTPAGE

 

A government-commissioned review examining problems with Australia’s Collins-class submarines found that inadequately designed logistical support arrangements were unable to keep an adequate number of boats at sea.

The review determined that this problem was later masked by other issues such as lack of leadership, maintenance overruns, inadequate provisioning of spare parts and crewing difficulties since the first submarine entered the water in 1996.

Australian Defense Minister Stephen Smith and Minister for Defense Materiel Jason Clare jointly announced the results of the Collins review on Dec. 12.

The country has struggled to meet operational requirements with its six Collins-class subs, which entered service between 1996 and 2003. Last year, the administration of Prime Minister Julia Gillard commissioned a study by John Coles, an independent expert from the U.K.

The report recommends steps over a three-year period to bring the fleet to the point at which two boats are available for operations at any given time; three are available 90 percent; and four for 50 percent of the time.

It also proposes a 25-point plan to reach what it considers the international benchmark for submarine operations by 2016, including reducing the full-docking cycle of each boat from three years to two years and having only one undergoing the full-docking cycle process at any given time.

“The Coles report essentially says that the basic flaw with maintenance and sustainment of the Collins Class submarine has existed since the first boat went into the water in 1996,” Smith said.

“This has been a problem which has bedeviled the Collins class for over 17 years and been a long-standing, entrenched difficulty for successive governments, for defense, for the Navy, the Defense Materiel Organisation and for [shipbuilder] ASC itself. It’s quite clear from the report that we fall substantially below any comparable international benchmark.”

Kym Bergmann, a defense analyst and editor of Asia Pacific Defence Reporter, said the report is “a damning indictment of Navy, the Defence Materiel Organisation and ASC ... which has been a government business enterprise since 2000.

“In addition to accepting and acting on all of the review findings, the government should privatize ASC as soon as possible — a process that unfortunately would take a minimum of two years,” Bergmann said.

The ministers also announced the findings into a review of the ability of the Collins boats to achieve their 28-year design life, finding no single reason they should not be able to.

The Collins Class Service Life Evaluation Program report also found no reason the subs cannot each have their lives extended by another seven- year operating cycle, if required. The extension would see the boats reach the end of their service lives between 2031 and 2038.

The Gillard government intends to build 12 large conventionally-powered subs from around 2019 and therefore needs confidence that the Collins boats will last the distance.

The third announcement concerned the establishment of a land-based test site in South Australia for the Future Submarine program. Known as the Submarine Propulsion, Energy, Support and Integration Facility, it will enable the testing of the new subs’ propulsion system before it is incorporated into the vessel.

“The land-based test facility will also help ensure that challenges encountered from the maintenance of the Collins-class fleet are addressed,” the ministers said.
