What is the future of pressurised submarine escape training?

By Frank Owen

Although there has been no (formal) public statement, it’s understood that the Royal Australian Navy (RAN) has revised its long-standing program to conduct pressurised submarine escape training (PSET). Any decision to cancel this in-country training would not have been taken lightly, so let’s consider the issues that would (or should) been considered.

Why is a submarine different?


Submarines are deadly machines. As Rear Admiral Peter Briggs has postulated in his paper “Strategic Sting”, their stealth makes them ideal instruments of foreign policy and, akin to a floating minefield, they demand a disproportionate level of resource to neutralise their effect. It is for this reason that more nations than ever before have started adding them to their orders of battle. These features also make them objects of fascination to the wider public.

Little wonder, then, that the loss of a submarine grips the world’s attention like few other accidents. They generate a feeling of helplessness in much the same way as situations where miners are stuck several hundred metres beneath the surface. Some examples of peacetime incidents where the submariners survived the initial accident are:
  • USS Squalus. This submarine sank in 243 feet of water in September 1939 due to the mechanical failure of a valve indicator. All 33 of the survivors were rescued using what is known as a Submarine Rescue Chamber (SRC), versions of which are still in service.
  • A short time later, HMS Thetis sank just outside Liverpool, UK, following flooding through a torpedo tube. Despite being so close to the surface that the stern was able to be lifted clear, 97 of the 101 on board perished because one of the escapers became trapped in the escape tower.
  • HMS Thetis
  • In 1953, HMS Truculent sank in the River Thames estuary following a collision and, although 64 of those that survived the accident made a successful escape, all were swept away by the strong currents and 57 died from exposure.
  • The Peruvian submarine BAP Pacocha sank in August 1988 following a collision with a fishing trawler. Before it sank, 33 managed to abandon the submarine, but several of the 22 trapped inside the submarine suffered injuries, some fatal, because of their unfamiliarity with the escape systems. Notably, this lack of familiarity arose because of a cost-saving measure by the Peruvian Government to stop submarine escape training.
  • Perhaps the most reported accident of the modern era was of the Russian submarine Kursk which, in August 2000, sank following massive explosions of her own torpedoes. The 23 survivors, trapped in an after-compartment that subsequently suffered heavy leaks from around the propeller shafts, were unable to be rescued and were at a depth beyond the capability of the Russian escape system. Sadly, the compartment flooded before any intervention was possible and all 23 perished.

When the worst happens…


A submarine is in trouble. As crew members struggle to keep their submarine afloat or maintain their depth, there may be sufficient time for some, or all, personnel to abandon ship on the surface. Once the submarine sinks (and can no longer surface), it is termed a “Distressed Submarine” (DISSUB). Conditions inside the DISSUB are likely to be fraught for those who have survived the initial accident. Mechanical systems that once controlled air temperature and quality are likely to be without electrical supply. The temperature of the DISSUB will fall to that of the surrounding seawater within a couple of days.

Emergency systems on board can control the two fundamental gases of oxygen and carbon dioxide within survivable limits for a few days, provided those systems remain operational. The internal pressure of the DISSUB is likely to be elevated because of the water that has almost certainly flooded into the submarine. Injuries will be a further complication for the survivors, especially if the accident has involved collision with another vessel or object.

Those inside are faced with decisions that will drastically affect their chances of survival. The choice of whether to attempt escape or await rescue by surface forces is heavily influenced by the conditions on board. Where the situation is deteriorating rapidly, escape may be the only option.

The decision to attempt an escape is a challenging one for the person termed the “Senior Survivor’”. Submarines today are fitted with systems that have been tested down to 180m, a depth equating the edge of the continental shelf, however, the risks increase with depth and operational guidance now recommends that attempting to escape at depths below 150m should only be undertaken as the last resort.

How does it work?


In simple terms, the escape system involves being equipped with a suit that incorporates a venting life jacket and a hood to contain the vented (and exhaled) air which keeps the head in air so that the escaper can continue to breathe “normally”. The escape is performed via a specially equipped airlock (the escape tower) that can be flooded in a short enough time to prevent nitrogen being absorbed into the bloodstream. At the same time, an inflation system provides air into the life jacket at a pressure that is continuously above the pressure inside the tower as it floods. Once the water pressure inside the tower is the same as the sea pressure outside, a spring in the upper hatch overcomes the sea pressure that has been holding it shut and the escaper floats to the surface.

The rate of change of pressure during flooding up is very significant. Equalisation needs to occur very rapidly if “the bends” are to be avoided and, at great depths, it’s likely that the escapers won’t be able to keep “clearing” their ears. This means that their ear drums may burst which is excruciatingly painful and can distract the escaper from the more critical message about the need to breathe.

The ascent itself is very rapid (it reaches about 2-3 metres per second) but it’s cold and dark until you approach the surface. Those who have experienced escape at depth describe a simple and relatively comfortable experience when escaping down to about 90m but beyond that, it gets physically harder and, from about 150m, something that’s increasingly risky (and frightening), especially in the tower itself.

What’s the History of PSET?


In 1946, Captain P. Ruck-Keene conducted a review of submarine escape for the Admiralty using the evidence of submariners who had escaped from submarines sunk immediately prior to and during World War II. While the report is some 72 years old, it contains data from a large number of successful and failed escapes from sunken submarines. We are very fortunate that there has not been a lot of data available in this area since then.

The report makes a number of relevant points:
  • The survivors in a sunken submarine contemplating escape “… must be regarded as quite incapable of doing anything but the simplest tasks. They are frightened, numb and stupid.”
  • 99 of the 103 people in HMS Thetis were killed because the fifth person to escape from the submarine panicked, did not follow the correct procedure in the escape tower, died and in the process rendered the escape tower inoperable so that none of the other survivors in the submarine could escape.
  • The committee recommended pressurised submarine escape training with the highest possible levels of fidelity. “… throughout the war, disasters and mistakes were almost entirely due to ignorance of simple physiological facts and lack of knowledge of how to use the equipment”. “No matter how simple the equipment is, successful escapes will never take place without proper training and knowledge”.

A stark reminder from the Ruck-Keene report for today’s submariner is that in war, waiting to be rescued from a sunken submarine is not an option. If one’s submarine is sunk in an operational area, escape is the only way out.

The training facility


For the escape to be successful, all those involved need to be trained and, most importantly, confident that the system works. Up until now, that has consisted of a combination of theoretical and practical training using a purpose-built Submarine Escape Training Facility (SETF); a tower containing a 22m deep water column with an escape tower at its base. The SETF was built at HMAS Stirling in Western Australia in the mid-1980s and has long been regarded as one of the best in the world.

The SETF is now over 30 years old and will need some investment if its systems are to be operated to the same levels of its original design. There have been periods where training was suspended because of mandatory system maintenance activities. While the annual costs of its operation and maintenance are believed to be less than $10 million, in the context of the reported $1 billion spent on submarine sustainment, this is not significant. How else can the Government meet its own obligations to provide a safe means of egress from the workplace?

Apart from some training accreditation shortfalls, partly due to the in-water instructors being exposed to high pressure levels through a combination of personal and professional diving, the rate of accidents has been remarkably low. Turkish research, for example, reported 41,183 training ascents from 30 and 60 feet without serious injury. This low escape training accident rate is also evident in other countries such as the United States, Australia, Canada, Japan, and Germany so it is possible that the Australian Navy’s decision to close the SETF is based on another factor.

In 1999, a paper by (then) LCDR Robyn Walker RAN (now Surgeon-General of the Australian Defence Force) described the Australian submarine escape and rescue organisation, stating that “…the RAN has an obligation to make every practicable effort to provide the safest work environment for its personnel”. In that same year, Occupational Health & Safety Assessment #29 into Pressurised Submarine Escape Training recommended the continuation of PSET and this was accepted by the RAN SUBSAFE Board. Sadly, the report appears not to have been published although the author retains a copy of the draft.

The training experience


The theoretical training involves comprehensive training in the mechanical systems and procedures that are fully aligned with the principles of competency-based training and assessment (CBTA). CBTA, of course, is unable to replicate the physical and psychological environment of a submarine accident so one hopes that the messages conveyed during the training are strong enough to remain in place when stress levels are extreme.

After some medical tests to check your ears and lung capacity, all of this is put into place with practical, experiential training by actually making an ascent from the tower at its base to the surface of the SETF water column. Throughout this ascent, the students are fully supervised by in-water instructors who can monitor and intervene if the student is not following the correct procedure. If everything goes well (and it’s all designed to), it’s a lot of fun and something you never forget.

The most important message that I took away from my own experience of escape training was never to hold my breath. This is a very real application of Boyle’s Law where the volume of air in your lungs increases as you come shallow. The most difficult part is the final 10 metres where the air volume doubles and, if you haven’t sorted out your breathing (or continuous exhaling if the suit hood has got ripped), you are very likely to burst your lungs (or more correctly, suffer from Pulmonary Over-Inflation Syndrome). To demonstrate this during training, a wine cask bladder is released from the base of the escape tank. No matter how little air is in it at the start, the bladder invariably bursts as it approaches the surface.

While it is relatively simple to remember to keep breathing, it is unnatural to just blow out because our instinct is that if we blow out, we then have to breathe in. The body cannot expel all the air in its lungs and it’s at that time that Boyle’s Law kicks in, increasing the lung’s air volume in inverse proportion to the pressure and the practical training provides that lesson. A student can be told time and time again not to hold his or her breath, but the number of students who have to receive a jab in the abdomen while actually in the water to remind them to breathe demonstrates the difficulty of applying lessons from the classroom into a different environment.

Conclusion


While everyone who has any connection with submarines hopes that the need for a real escape from a sunken submarine will never arise, it would be a great concern if the first time a submariner has the physical and psychological experience of escape is in the dark, in cold water, with no instructor support and when the escapee’s life (and that of his or her colleagues) depends on his or her capacity to remember the drill. Should the escaping submariner fail in this process and block the escape route, the members of the crew remaining in the submarine are then likely to be fatally trapped.

The process of the submarine escape process clearly contains risks; some during training and many in the actual escape. It may be possible to avoid the training risks but that merely transfers them to the poor sod next in line to climb into the escape tower for real. As an under-water medicine doctor said to me in 1999, the risks of doing escape training are far less than the risks of NOT doing escape training.

Facts about the advances in nuclear engineering

Comment: Submarine Institute of Australia

An opinion article on the Quadrant website written earlier this month (which can be found by clicking here) fails to consider many of the critical issues associated with the Future Submarine Program.

The only areas where nuclear submarines have unarguable advantages are sustained speed and endurance.

The Submarine Institute of Australia (SIA) recognises the speed/endurance advantages of nuclear-powered submarines over conventionally-powered submarines, however, the perception that a move to procure this type of technology in a time-frame commensurate with sustaining a viable submarine capability – via a long-lead procurement program – shows an unrealistic appreciation of the complex factors which exist.

The Australian Environmental Protection and Biodiversity Conservation Act recognises the protection of the environment from nuclear actions as a matter of national environmental significance.

Nuclear actions include establishing a nuclear installation. Hence, a change in federal legislation is required before any commitment by an Australian Government is made to pursue any nuclear power program.

While the SIA considers that discussion around the long-term planning for a nuclear-powered submarine force is necessary to ensure that all the issues are understood, the consequent delay in planning and procurement for the sustainment of the submarine capability, involving nuclear studies in the short-term, would result in a critical gap in submarine capability.

It is simplistic in the extreme to suggest that Australia could approach any of its allies possessing a nuclear submarine capability with a proposal for a rapidly executed leasing arrangement or “off-the-shelf” purchase. The infrastructure to support these vessels is highly complex, as are the sensitivities of the associated technology. None of the nations with a nuclear submarine capability would simply “hand over” that technology.

The most important issue is continuity of our submarine capability. In the short-term, this can only be achieved by continuing with conventional submarine technology.

At the rate that all relevant forms of submarine technology is advancing – hull design, conventional propulsion and combat system (sensors, processing and weapons) – the progression towards nuclear power will, hopefully be ongoing, but it will take time.

The people of Australia must be given the facts regarding the advances in nuclear engineering and the benefits that Australia can gain from embracing the technology. Nuclear-powered submarine technology is but one aspect of these benefits.

The importance of underwater robotics for undersea warfare in Australia

By Andrew McConnell

Undersea robots are growing in importance for modern navies and the advances in autonomous unmanned underwater vehicles (UUVs) are moving forward at a rapid rate. Whether any nation has a dominant advantage in this area is less clear for many reasons. What is the state of integration of UUVs into undersea warfare and how can Australian industry be developed to support it?

Initial online searches reveal many high-level articles discussing broad UUV concepts, but published technical papers are less common. This is unsurprising, as most companies and governments working in this field are playing their cards very close to their chests. Undersea warfare is, by its nature, stealth warfare and it is difficult and protracted in execution. Maintaining appropriate levels of discretion and secrecy is standard operational procedure. Likewise, speculation on external competitors’ progress is also standard practice.

The US Navy has been following a roadmap for UUVs which extends through to 2020 and UUVs are a significant component of naval defence plans for the next 20-30 years. Recently, the US Navy has undergone a re-organisation to mainstream the complementary warfighting effects of unmanned warfare systems. The silo Unmanned Warfare Systems directorate has been merged with the office of the Director of Warfare Integration to oversee unmanned integration and accelerated prototype acquisition where possible.

As observed in “Achieving Secrecy and Surprise in a Ubiquitous ISR Environment – Analysis” (Eurasia Review 2018-02-04), development of undersea warfare capability is undertaken in stealth mode. This restricts information leaks to opponents, but with rapid advances in robotics and artificial intelligence, the advantage margin is shrinking and broader cooperation is becoming encouraged with allies.

The advantage of autonomous systems in undersea warfare is that they allow a very asymmetrical conflict. Conventional submarines are all of a similar size due to the requirements of having human crew members, who require air, food, heating and sanitation. All that air-filled human workspace means buoyancy, which leads to the major problem for submarines – getting them to sink. Further, all sensor data must be presented to human eyes and ears through screens, lights, speakers and buzzers, which consume further power and space onboard.

Now consider the unmanned vehicle which has none of the support infrastructure. It can be smaller, denser and it consumes less power. It can loiter in freezing cold deep water or drift into position on a slow current. It can remain silent and listen, without breathing or heartbeats.

Smaller vehicles mean more of them can be deployed, allowing swarm multipoint illumination. Recent research investigates swarming behaviours of robot UUVs and improvements in tracking and chasing mobile targets. This research is being undertaken and authored not only by large defence industry companies and established research centres, but by smaller third-world or non-state researchers using very low-cost equipment.

Other advantages of smaller UUVs over manned vessels are:
  • Potential for aerial deployment;
  • Specialisation with type-specific sensors, rather than requiring a generalist platform to justify investment;
  • Low-cost deterrent with stable ongoing costs (no pay rises!);
  • They are less obvious and hard to detect (this makes them a long-term threat that could never be confidently eliminated);
  • Unmanned vehicles can assume a greater variety of shapes - round, flat, atoll-shaped (easier to camouflage with natural organisms);
  • Solid neutral weight advantage reduces buoyancy problems; and
  • Smaller UUVs are able to navigate smaller waterways.
This last point opens up some interesting opportunities for Australian industry because manufacture and launch of small vessels does not require ocean frontage and expensive shipyards. In fact, launches can be conducted from facilities adjacent to rivers, channels, dams or inland creeks. Vessels can be deployed from smaller inland bases on small rivers. This means a lower start-up cost to industry and the potential for widely distributed low-cost support facilities for defence.

Australia has considerable experience in the fundamental art of submarine vehicles of all sizes. This field will now subsume deep learning, autonomous operations, crewless hull design, new materials, new sensors and new power sources. Small companies should be able to find a “fit” with UUV projects of smaller size.

Unmanned vehicles have broader design parameters in size, speed, longevity, stealth and specialisation, which could lead to a varied eco-system of solutions. Each solution must be addressed by a countermeasure.

Is it also prudent to anticipate unknown UUV capabilities? No, but it is prudent to have rapid research and development infrastructure to develop countermeasures.

Besides the large manned submarines and smaller UUVs, there exists potential for young Australian industries to cut their teeth on cheap autonomous decoys and disguised commercial-off-the-shelf products. This would encourage the industry ability to exercise rapid assessment and trial of new technologies.

In November 2018 in the Jervis Bay area of New South Wales, the Department of Defence is planning the Autonomous Warrior exercise to showcase a range of new products. Perhaps the exercise could also incorporate an industry technical countermeasure exercise, with the aim of rapidly prototyping countermeasures for each new product.

Realistic planning for future nuclear propulsion of Australia’s submarines

By Nautilus

Recent public debate about nuclear propulsion for submarines has been notable for the polarised viewpoints on the issue.

On the one hand, the strategic advantages of nuclear propulsion for submarines have been acknowledged, while on the other, the lack of experience within Australia of nuclear power for civil or naval use demands a deliberate program to move up the learning curve. It will take at least a decade to meet community expectations for internationally-recognised regulatory standards for safety, security, efficiency and sustainability.

The first challenge is to contemplate nuclear energy as a beneficial adjunct to renewable energy generation and advanced storage that is the ultimate goal of an emissions-free electrical power generation network.

What are more likely to be accepted are small, road-portable modular reactors based on proven pressurised water cooling, which is, coincidentally, the norm for naval propulsion. The attractive feature of small, modular reactors is their size and mass is small enough to be easily transportable so they can be constructed and fuelled remotely from their operating sites and after many years of effective operation, they can then be removed in the same way for safe decommissioning in a similar remote site.

The connection between nuclear power stations and trained naval operating personnel has been recognised in other countries such that the education and training of operators and maintainers of naval nuclear reactors are readily transitioned to civil reactor operations after their naval service. This is even more the case when the civil reactors use the same pressurised-water-reactor technology, as is the case with most small modular reactor programs.

For Australia, there is a critical national need for energy security and this is sufficient to justify contingency planning, such as the installation of a single small modular reactor at Lucas Heights in southern Sydney for familiarisation, research and development, and for the education and training of civil and naval professional staff for operation and maintenance of such reactors. This would help to build the foundation workforce for this industry.

Only then could Australia realistically consider the next generation of submarines beyond the current acquisition program for the future submarines, which will itself have many challenges in energy generation, conversion and storage. The design of the Shortfin Barracuda, now underway, will address air-independent propulsion in one form or another and, also, the related issue of energy density in battery technologies. This research and development is already time-constrained. Random thoughts of nuclear propulsion should never be permitted to raise the risk of a capability gap arising from resulting delays occurring in the Future Submarine Program (FSP).

Beyond the urgency of the FSP, there is sound argument to plan for the transition to the greater performance and availability of nuclear propulsion, but this needs a research and development program in its own right and a concerted program to build up the scientific, engineering and operational workforce.

We can reasonably expect support from our allies and business partners in the US, UK or France, but ultimately, Australia needs to set and meet our own demanding standards for safety, security, efficiency and sustainability. This will take significant time – even if we start immediately – as the Submarine Institute of Australia believes we should.

Given the time it would take for serious consideration of nuclear propulsion of the next generation of Australian submarines – after we have an effective future submarine force at sea – and to garner the experience and conduct the workforce development which is essential, the process should start now.

Growing up to deliver submarines

By Christopher Skinner
Executive Committee Member, Submarine Institute of Australia

The following advertisement appeared recently soliciting applications for positions in the Australian Government’s Department of Defence Capability Acquisition and Sustainment Group SEA1000 Future Submarine Program. To my surprise, it has evoked several indignant or agitated questions from colleagues and others with long engagement in submarine matters (see http://sea1000.gov.au/employment/):

“Individuals can apply for positions under direct hire contracts by the Commonwealth of Australia or through companies with authority to provide staff to Australia in support of defence programs. Contracts can vary from 3 to 7 years.

Up to 60 personnel will be recruited within the next 12 months as design of the Future Submarine progresses. Individuals with proven skills and appropriate experience in submarine design, submarine systems design and submarine program management including business management are required for key roles located in Canberra and Adelaide (Australia) and Cherbourg (France).

These people will be working as members of the Future Submarine Program Office, supporting the Commonwealth in upholding its role as an intelligent partner with DCNS and Lockheed Martin Australia.

Positions available range from senior technical positions to mid-level roles. All positions will include a requirement to mentor and train our Australian workforce. Priority has been placed on the selection of personnel for senior positions including:
  • Technical Director (Platform) – Adelaide (click here for position description)
  • Assistant Technical Director (Platform) – Cherbourg (click here for position description)
  • Technical Director (Combat System) – Adelaide (click here for position description)
  • Assistant Technical Director (Combat System) – Cherbourg (click here for position description)
  • Test and Evaluation Director – Adelaide (click here for position description)
  • Material and Supplier Base Director – Adelaide (click here for position description)
  • Shipyard Infrastructure/Workforce Director – Adelaide (click here for position description)

Potential applicants will need to demonstrate substantial management experience at a senior level gained in a technologically and commercially demanding environment – preferable the submarine industry.

Mandatory: Applicants must meet requisite attributes for the position for which they apply.

Interviews will begin the week of 9 January 2017 at the Australian Embassy in the US and within Australia thereafter. Applications or queries should be forwarded to submarine.mobilisation@defence.gov.au.

To me, this all seems logical and timely to ensure the Australian Government is well staffed to perform its proper role effectively and to engage with the main contractors DCNS (platform integration) and Lockheed Martin Australia (LMA, combat system integration). The only further positions that might be added to the above list would be someone placed in the US to support the AN/BYG-1 combat management system, Mk 48 wire-guided torpedo, both jointly developed by the US and Australia, and other US-sourced programs relevant to the Future Submarine Program, as well as a deputy director technical with responsibility for propulsion systems integration, a non-trivial task, within the overall platform integration role.

The role of these people will be as leaders of the Commonwealth teams that form the customer group with whom industry works on a daily basis. These people will be delegated authority to approve documents and specifications on behalf of the customer (the Australian Government’s Department of Defence Capability Acquisition and Sustainment Group). This is part of the design development process which has a great deal to be accomplished before procurement of services and materials begins – even long lead items – or construction and integration can begin.

Some of the objections raised relate to the first interviews taking place in Washington DC before those in Australia. Frankly, I do understand this would surprise many people who have not experienced the intensity and richness of scientific, technological, engineering and commercial talent that is concentrated in the Washington area, especially the United States Naval Sea Systems Command (NAVSEA) in Crystal City and nearby.

I have surmised that the interviews in Washington DC are to try to attract US-experienced personnel to join the program. They will provide best-practice experience based on the USS Virginia-class submarines and other programs. However, comments from colleagues have included:

“There is an underlying question about Australian industry involvement. I thought we were to build some Australian sovereign capability with Australian industry. Are we to create an Australian NAVSEA as custodian of some submarine knowledge, disconnected from Australian industry? We now learn that RAND Corp has been tasked by the Government to develop yet another paper on lessons learned in building up and sustaining a workforce for the Australian shipbuilding industry. A US corporation to advise on the Collins, ANZAC and Huon experiences, and the availability and training of Australian managers, engineers, draftspersons, electricians, welders, fitters-and-turners, shipwrights, etc for the Royal Australian Navy’s future submarine and shipbuilding programs? When does Australia shed its colonial past and stop asking Washington, London, and now also Paris, for direction and instead start believing in its own considerable track record and capacities – not least its human resources? The last time a US designer had to build a manned platform that had to pay the electricity bills was circa 1956 and the last operator that swiped the credit card was BLUEBACK circa 1990. While I note the UUV kiddies now have taken up that ‘pay-the-bill’ challenge, they are a very different crowd to those working the ‘SSN meat-grinder’. So it is almost three generations since somebody designed a fighting boat for non-nuke ops in the US and just a generation since somebody put on a snort.”

My instant response to these concerns is that what NAVSEA would bring to this highly challenging program is the process for managing it, not the design itself, which will be the responsibility of DCNS primarily, a highly-experienced designer of submarines – nuclear and conventional – and on air-independent propulsion for the latter.

I, therefore, reject the doubts on the suitability of NAVSEA people to contribute effective leadership and management to the program. I also reject the suggestions that this overlooks highly qualified and experienced Australian professionals; they will be in great demand, but very short supply for a program of this magnitude.

To illustrate how far we have to travel up the industrial-capability curve, Australia’s only school of naval architecture was closed recently (according to media reports in December).

We must learn from our past experience of major naval programs – good and bad – and apply all those lessons in collaboration with experienced designers, builders, integrators and sustainment people from where we can attract them. This is an extraordinary program to meet requirements that cannot be met off the shelf so that alone should attract innovative people from around the world.


I truly hope we concentrate on growing our scientific, engineering and industrial experience to deliver highly effective submarines in a program which becomes an exemplar for Australian and international endeavours of similar complexity.

2016 SIA Conference Report, Day 2 – Election of Donald Trump will benefit Australian defence industry

Political leaders took centre stage on the final day of the Submarine Institute of Australia (SIA) 8th Biennial Conference 2016, which was held at the Shine Dome in Canberra.

This was particularly timely given the election of Mr Donald Trump as US President the previous week, which raised debate in political circles about how this would impact on the Australia-US alliance.

In a doorstop at the conference, the Minister for Defence Industry, Hon Christopher Pyne MP, said Australia is very much “linked in to the ‘Trump Team’” and Australians are “not strategic bludgers”.

In his keynote address to the conference, Minister Pyne said the Government is placing investment in defence at the forefront of promoting economic development.

“We want to use defence to underpin our economic prosperity and to put the skills and innovation that characterise our defence industries at work, to form the basis of the smart, high-tech manufacturing of the 21st century,” the Minister said.

The Government will be investing just under $200 billion in the decade from now until 2025-26 in building defence capacity and growing Australia’s defence budget to at least 2 per cent of the nation’s gross domestic product.

Despite the long lead times, time remains critical, according to the Minister.

“Time wasted at the beginning of any project is time that must be made up at the end,” Mr Pyne said. “That means you must get matters right from the start. We must be able to realise our ambitious goals.”

The Minister has a positive view about the election of Mr Trump, saying: “I think it’s fair to say that given the consistent rhetoric around boosting military spending in the US by tens, if not hundreds, of billions of dollars, there will be increased opportunities for Australian defence industry.”

The Shadow Minister for Defence, Hon Richard Marles, delivered the closing address for this year’s conference.

Like many, he is enthusiastic about the increased investment in defence spending, including on the design and construction of the future submarines, and noted that a future Labor Government will be a custodian of the future submarines, given the length of the project.

“On national security, our (Labor’s) first instinct is bipartisanship,” Mr Marles said. “Defence is, generally, not an area of party political divide. Minister Pyne is right to point out the Trump administration will provide numerous opportunities.”

Mr Marles added that despite Labor’s bipartisan approach, it intends to hold the Government to account.

In addition, he said Labor has a “traditional view” about the defence portfolio in that there should be one Minister for Defence.

Mr Marles pledged all existing contracts and undertakings would be honoured – to avoid sovereign risk – under a future Labor Government.


His address completed the most successful SIA conference to date. The event wouldn’t have been possible with the support of the conference sponsors.

2016 SIA Conference Report, Day 1 – Positive vibe about significant submarine investment

The opening plenary session, which was held on Day 1 (or the second day) of the Submarine Institute of Australia (SIA) 8th Biennial Conference in Canberra, was dominated by positive themes.

This was largely attributed to the fact that in the past 12 months since the previous SIA conference (in Adelaide), the Federal Government has announced the international design partner (DCNS) and the combat system integrator (Lockheed Martin) for the future submarines, among other related matters.

The first presenter on Day 1 was the Chief of Navy, Vice Admiral Tim Barrett AO, CSC, RAN.

Noting the past 12 months has been a period of significant change, Vice Admiral Barrett said the future submarines would draw on the experience gained from both the Oberon and Collins-class submarines.

“We have learned; indeed, we have evolved,” Vice Admiral Barrett said. “More importantly, we continue to learn and we continue to evolve and to mature.

“The Government’s decision to construct an Australian submarine capability around a force of 12 boats gestures to an increased awareness of the submarine as a core element of Australian defence strategy in an increasingly challenging environment.”

He said sustainment and training will be critical to the success of the future submarines.

“My new focus is on the capability,” Vice Admiral Barrett said. “Capability, capability, capability.”

The next speaker was Rear Admiral Michael E. Jabaley USN, Program Executive Officer for Submarines, US Naval Sea Systems Command.

In his presentation, which examined cooperation between US and Australian submarine forces, he said the Royal Australian Navy and the US Navy have a “firm foundation for cooperation” and that building the future submarines will enhance the alliance.

Rear Admiral Jabaley said the US has two armaments cooperative projects with the Royal Australian Navy, the MK 48 Heavyweight Torpedo and the AN/BYG-1 Submarine Tactical and Weapon Control System.

“To execute these projects, the navies have established Joint Project Offices in Washington, D.C.,” he said. “The Royal Australian Navy is our partner, not a customer.”

With an eye to the future, Rear Admiral Jabaley said: “We look forward to continuing to work with Australia to make the future submarine the most advanced and capable conventional submarine in the world.”

Rear Admiral Steve Johnson USN (rtd), General Manager Submarines, Capability Acquisition and Sustainment Group (CASG) within the Department of Defence presented on submarine program management.

He said the path to the future submarines starts with the Collins-class submarines. Other points from his speech included:
  • The 12 future submarines provide sufficient platforms to be a significant deterrent;
  • Defence is aiming to maximise the role of Australian industry;
  • Consistent, daily attention to detail is important for effective program management;
  • What is done now with concept design is going to be quite different from detailed design and construction; and
  • The nature of our work with DCNS is that DCNS proposes and the Commonwealth decides.
