Tasmania Secures Role In Future Submarine Program

Amelia McMahon, Defence Connect
23 March 2017

The University of Tasmania (UTAS) has signed a memorandum of understanding with four French defense and maritime technology institutions for work on the $50 billion DCNS project.
Although the fleet will be built in Adelaide, the Australian Maritime College (AMC) in Launceston will deliver teaching and research to the manufacturers that will build the 12 Shortfin Barracuda submarines.
UTAS deputy vice-chancellor Professor Monique Skidmore signed the MoU with the four French institutions: ENSTA ParisTech, École Centrale de Nantes, CentraleSupélec and École Polytechnique.
"This MoU will result in the university working with our French partners to deliver teaching and research which will inform the delivery of the next-generation submarine fleet for the country," Professor Skidmore said. "Universities such as the University of Tasmania, South Australian universities and the French consortia will together create the new generation of highly skilled workers required to research, design, build and maintain the next generation submarine fleet."
Professor Skidmore said the memorandum recognized the world standing of the university’s AMC in both teaching and research, and underlined the considerable promise of defense and design to northern Tasmania’s future.
"Arrangements such as this provide a platform upon which we can expand our existing strengths, along with the development of completely new economic sectors for the region and the state," said Professor Skidmore.
"This agreement has come about because of our university’s capacity for interdisciplinary research and our highly-regarded pedigree in the STEM disciplines of science, technology, engineering and mathematics. It is why the university is pursuing a vision for a STEM Precinct in Hobart, which would considerably enhance these strengths, which could then be leveraged for the benefit of the entire state."
The institutions will all work with DCNS on the project and the programs are due to start in September next year.
The contract for the design and construction of the Future Submarines was awarded to the French government-owned DCNS in April 2016 and signed in September 2016.
The French company was selected by the Australian government for the contract over German TKMS and Japanese Mitsubishi Heavy Industries and Kawasaki Shipbuilding Corporation offerings.
DCNS has stated that the Shortfin Barracuda pushes submarine stealth capabilities into a new realm, using pump-jet propulsion instead of the traditional propeller. To add to its stealth capabilities, hydroplanes on the submarine will retract to reduce drag and noise.
The fleet will replace the six Australian-built Collins Class submarines that have been in service since 1996.
Tasmanian Minister for State Growth Matthew Groom gave a statement explaining the government wanted to ensure Tasmania was not missing out on its share of defense spending.
"In order to increase our share of defense spending, we need to ensure that we have the skills and the linkages with the defense sector to contribute to significant national projects such as this," he said.
"It will put the university's [AMC] at the forefront of the teaching and research work that will inform the delivery of Australia's submarine fleet."

U.S. Navy, Congress Eye Buying Carriers in Blocks of Two, Folding in Submarine Material Purchase

22 March 2017 

WASHINGTON — The Navy and Congress are actively looking at building aircraft carriers in sets of two to reduce acquisition costs and grow the fleet to 12 carriers, as well as considering including purchases of submarine materials with them to achieve cost reductions over three programs. 
“We’re going to try to buy carriers in blocks of two,” Vice Adm. David C. Johnson, principal military deputy to the assistant secretary of the Navy for Research, Development and Acquisition, said March 22 at a Defense Programs Conference sponsored by McAleese and Associates. 
In the Navy’s 2016 Force Structure Assessment, the number of carriers needed by the Navy was set at 12, two more than the current 10, a number which that climb to 11 this year with the commissioning of Gerald R. Ford, the lead ship of a new class planned to begin sea trials this spring. 
Affording the fleet growth to 355 ships, including the carriers, is a challenge acknowledged by Congress.
“We have to get the glide path to 355 [ships] right,” Rep. Robert J. Wittman, R-Va., chairman of the House Armed Services seapower and projection forces subcommittee, said at the conference. “We cannot afford anything less. If we don’t, we create additional challenges going forward.”
Wittman said the subcommittee “will come back at this to purchase two [carriers] at a time.”
Johnson also said that it would be advantageous to include in the buys the procurement of materials for the Columbia-class ballistic-missile submarine and the Virginia-class attack submarine to achieve economies of scale over all three nuclear-powered ship programs.
The Navy has been looking at procuring the next ships of the Gerald R. Ford class in a two-stage strategy, buying two hulls in advance to save material procurement costs and then installing combat systems on the ships when the latest systems are available closer to the commissioning date. 
Wittman said Congress needs to look at “incrementally funding ships,” while acknowledging, “I know the appropriators don’t like that.”

Taiwan Has to Build its Own Submarines Because Nobody Is Willing to Anger China

Kyle Mizokami, Popular Mechanics
21 March 2017

The president of Taiwan has announced the conclusion of the nation's disappointing, decades-long search for someone—anyone—to sell the country attack submarines for its defense: Nobody will, and so the island country will build its submarines. USNI News, citing the Japanese Kyodo News Agency, reports that Taiwanese President Tsai Ing-wen announced the start of the submarine program today at a Republic of China (Taiwan) Navy base.
Lying just 120 miles from mainland China, Taiwan, or the Republic of China, has been under threat of invasion since splitting from Communist China in 1949. As China's military strength has grown in recent years, the threat of invasion has increased and Taiwan has sought to build a fleet of diesel electric submarines. Submarines are an ideal weapon of defense for Taiwan, capable of sinking invasion fleets and breaking any blockade China might impose on what it considers a "breakaway province".
In theory, Taiwan's plan shouldn't be a problem. There is a vibrant non-nuclear submarine industry worldwide, with Russia, Japan, France, and Germany all leaders in diesel electric attack submarine design. Unfortunately for Taiwan, as China's economic power has increased, Beijing has used that power to discourage other countries from selling submarines to Taiwan. Today, no one will sell the country submarines for fear of retaliatory economic action by China.
What about American shipyards? Some, such as the Connecticut-based General Dynamics Electric Boat, produce only nuclear-powered submarines. That is way too much submarine for Taiwan, which doesn't need large ships with the ability to circumnavigate the globe. The long range of nuclear subs would make them offensive weapons, and Washington is committed to selling Taiwan only defensive arms.
In 2001, the Bush Administration promised to build diesel-powered submarines for Taiwan, but that never happened, for a number of reasons. The move would have deteriorated U.S.-Chinese relations. Plus, the U.S. Navy does not want domestic shipyards to produce diesel-powered subs. The Navy prefers an all-nuclear force and is afraid that if local shipyards made the less desirable (but cheaper) alternative, Congress may actually force the American Navy to buy them.
In the meantime, Taiwan's navy has just four submarines. The two newest subs Hai Lung ("Sea Dragon") and Hai Hu ("Sea Tiger") were ordered from the Netherlands in 1980 and delivered by 1988. Even older are the Hai Shih (ex-USS Cutlass) and Hai Pao (ex-USS Tusk), which were built for the U.S. Navy during World War II. The submarines were transferred to Taiwan in the early 70s with their torpedo tubes welded shut. Each is more than 70 years old, making them the oldest submarines in service anywhere. The two geriatric attack boats are too old for frontline service and are instead used to train anti-submarine warfare forces.
This new effort to make homebuilt subs will be a joint project between the CSBC shipbuilding corporation, the Taiwanese government and navy, and the National Chung-Shan Institute of Science and Technology. Taiwan reportedly wants a submarine in the 1,200 to 3,000-ton class, which is a reasonable size considering the main mission of the sub fleet is to defend a relatively small island. The only submarine the U.S. currently builds, by comparison, is the 7,800-ton nuclear powered Virginia-class attack sub.
Taiwan will probably get guided torpedoes such as the Mark 48 ADCAP anti-ship/anti-submarine torpedo, from the United States. According to USNI News, Taiwan expects the process to take ten years to mature consisting of "four years (for design), four for construction and two additional years of testing."
Taiwan will basically start from square one in designing this submarine. The country is so bereft of submarine design experience that in 2015 it was reportedly ready to tear down one of the World War II-era subs to figure out how to build modern submarines. Taiwan will lean heavily on outside help. It was reported in 2015 that "more than twenty US and European companies" have expressed interest in working with Taiwanese companies on the submarine project.
If Taiwan's effort to build submarines is successful, then Beijing's pressure to halt sales from other countries could backfire. Taiwan could build submarines with features other countries might be reluctant to sell, such as vertical launch silos for long-range missiles that could hit the mainland, giving the island country a retaliatory strike capability that Beijing would prefer Taiwan didn't have.

Heinrich, Udall Seek To Dedicate Nuclear-Powered Sub ‘USS Los Alamos’ In Honor Of LANL’s 75th Anniversary

Staff, The Los Alamoz Monitor Online
21 March 2017

U.S. Sens. Martin Heinrich and Tom Udall introduced a resolution Tuesday urging the Secretary of the Navy to name the next nuclear-powered submarine of the U.S. Navy “USS Los Alamos” to honor and recognize Los Alamos residents contributions to the Navy.
“Los Alamos National Laboratory employs some of the best and brightest minds in the country and, for nearly 75 years, has been indispensable to our national security and global stability,” said Heinrich, a member of the Senate Armed Services Committee. “Naming the next nuclear-powered submarine USS Los Alamos will recognize and continue to forge the longstanding relationship between the Navy and the entire Los Alamos community.”
“Los Alamos and the United States Navy have maintained a strong bond since the dawn of the nuclear age. It is a bond that has strengthened our national security and helped bolster science and technology in New Mexico and around the world. A submarine named USS Los Alamos would speak to this strong history and would be a formidable force when underway,” Udall said. “Los Alamos National Lab plays an essential role in combatting existing and emerging threats to our security and in strengthening New Mexico’s economy. As a member of the Senate Appropriations Subcommittee on Energy and Water, I will keep fighting for LANL to receive the support and resources it needs to fulfill its essential mission for New Mexico and the United States.”
Next year will mark the 75th anniversary of the founding of Los Alamos National Laboratory (LANL). Since its founding, LANL has played a critical role in national and international security, research, and science.
Los Alamos residents working on the Manhattan Project, many of whom were U.S. Navy personnel, helped bring about the end of World War II.
LANL later designed, tested, and certified much of the nation’s nuclear deterrent and continues to ensure the annual certification of the nation’s nuclear stockpile. Work in Los Alamos during the Manhattan Project also provided the technical understanding in nuclear energy that led to the Naval Propulsion Program.
The community in New Mexico has strongly supported recognition of the contributions that residents of Los Alamos have made to the Navy. The USS Los Alamos Commissioning Committee has led an ongoing community effort to name a submarine the USS Los Alamos.
In December 2016, Heinrich facilitated and hosted a meeting between the USS Los Alamos Committee and Navy Leadership to advocate for a future USS Los Alamos.
"The USS Los Alamos Commissioning Committee would like to express its gratitude for the support of Senators Heinrich and Udall," said Committee Chair Jim Nesmith. "We believe this resolution will clearly demonstrate to the Secretary of the Navy that Congress understands the historical and ongoing connection between Los Alamos and the U.S. Navy, and strongly supports naming of a submarine the USS Los Alamos."
“Naming a nuclear submarine USS Los Alamos will remind the fighting crew of the world-altering history that was created in Los Alamos and of its continuing contributions that have so strengthened the United States Navy ever since,” said Tom Gutierrez, president of the New Mexico Council of the Navy League of the United States. “This resolution will make evident to the Secretary of the Navy the enthusiastic support and deep understanding of the Congress of the United States of the importance of Los Alamos in today’s world.”
Los Alamos Chamber of Commerce Director, Nancy Partridge, highlighted the economic impact this would have in the community, stating, “Naming a submarine the USS Los Alamos will recognize the long history of our community’s work on behalf of the Navy, and Los Alamos tourism and commerce will benefit greatly from the opportunity to celebrate this relationship.”
Last year, the New Mexico Congressional delegation sent a letter to Navy Secretary Ray Mabus supporting the citizens-based initiative requesting the designation of a future nuclear-powered submarine as the USS Los Alamos.
Here is the full text of the resolution:
Expressing the sense of Congress that the Secretary of the Navy should name the next nuclear powered submarine of the United States Navy the ''USS Los Alamos''.
Whereas the people of Los Alamos and the Navy have a 74-year relationship that continues from the Manhattan Project through the creation of a nuclear Navy and into the current ocean-borne leg of the strategic nuclear triad of the United States;
Whereas the contributions of the people of Los Alamos and surrounding communities allowed the Navy to keep its offensive edge from World War II, through the Cold War, continuing to the emerging conflicts as of the date of adoption of this resolution;
Whereas Captain “Deke” Parsons was one of the first residents of Los Alamos and, along with Laureate Ramsey, oversaw the safe delivery, assembly and loading of the nuclear bomb that led to the surrender of Japan in World War II;
Whereas the people of Los Alamos and surrounding communities played a critical role in designing the nuclear portion of the first nuclear weapon to enter the arsenal of the Navy, known as the Regulus, along with atomic depth bombs, torpedoes, rockets, and even next generation weapon systems like the B61-12 precision-guided nuclear bomb;
Whereas the people of Los Alamos designed the warheads that armed the first generation Trident submarine-launched ballistic missiles of the Navy and the follow-on Trident II missile warheads used by the Navy;
Whereas the research into nuclear energy conducted by Los Alamos during World War II advanced the technical basis for the development of the nuclear propulsion systems of the Navy used aboard Los Angeles, Seawolf, Ohio, and Virginia Class submarines along with multiple naval aircraft carriers today;
Whereas the people of Los Alamos and Los Alamos National Laboratory host United States Naval Academy midshipmen every year to provide hands-on scientific and engineering experience working to solve real world challenges in national security, thereby directly contributing to the development of future Navy leadership;
Whereas the people of Los Alamos carry the solemn responsibility to assess the sea-based nuclear deterrent carried aboard Navy fleet ballistic missile submarines;
Whereas naming a submarine Los Alamos will recognize and continue to forge the longstanding relationship between the Navy and Los Alamos;
Whereas the year 2018 will mark the 75th anniversary of Los Alamos National Laboratory; and
Whereas the distinctive service and contributions from the people of Los Alamos to the Navy merits naming a vessel that embodies the heritage, service, fidelity, and achievements of the residents of Los Alamos and surrounding communities in partnership with the United States Navy;
Now, therefore, be it Resolved by the Senate (the House of Representatives concurring), That it is the sense of the Congress that the Secretary of the Navy should name the next nuclear powered submarine of the United States Navy as the “USS Los Alamos.”

New U.S. Navy Team Promoting Unmanned Systems Integration On Submarines

Marc Selinger, Defense Daily
31  March 2017

The U.S. Navy has stood up a team within the past year to promote the integration of unmanned systems with submarines, a service official said March 21.
The team brings together various program offices to promote a common set of interfaces for deploying unmanned systems from submarines, said Michael McClatchy, director of advanced undersea integration at Naval Sea Systems Command. Rear Adm. Michael Jabaley, program executive officer for submarines, called for the group's formation, and the team was officially created in July.
Submarines have various ways of launching unmanned systems, including dry deck shelters, torpedo tubes and smaller delivery mechanisms, and the Navy wants to ensure industry and academia know how to build unmanned systems that are compatible with those launchers, McClatchy said at a Marine Technology Society breakfast in Arlington, Va.
"By building to those interfaces, it makes it easier for us to get" an unmanned system  into a submarine, McClatchy said.
At the same breakfast, Chief of Naval Research Rear Adm. David Hahn revealed that Rear Adm. Tim Gallaudet, the Navy's oceanographer and commander of Naval Meteorology and Oceanography Command (NMOC), plans to launch a government-industry task force to improve the nation's understanding of ocean science. Hahn and Gallaudet intend to lead a meeting later this week to further define the task force's membership, Hahn said.
"It is clear that we as a nation need to be at the forefront of [ocean science], and not just for naval applications but for lots of reasons," he said. "Generationally, we need to be interested again for the right reasons in all of the ocean."
According to NMOC's website, the command "provides environmental information to help naval and joint forces operate more safely and effectively, and make better decisions faster than the adversary."

Ten years on: The terrifying explosion that killed two submariners

The tragedy occurred when the nuclear-powered HMS Tireless was under the Arctic ice cap.

Gayle Herald, Plymouth Herald
21 March 2017

PLYMOUTH, UK – March 21, 2007, will forever be etched into the memory of the crew of HMS Tireless.
The submariners battled furiously for more than 40 minutes to rescue two trapped comrades after an explosion under the Arctic ice.
Leading Operator Mechanic Paul McCann, aged 32, and Submariner Anthony Huntrod, 20, were killed in the early hours of Wednesday, March 21, 2007, following the explosion onboard the Devonport-based submarine.
The blast in a confined compartment of the nuclear-powered sub, which was submerged under the Arctic icecap during a joint British-American exercise, was caused by a damaged Self-Contained Oxygen Generator (Scog) moments after it was activated by one of the men.
It later emerged the device - used to boost oxygen levels on submarines - may have been recycled from a hazardous waste dump at Devonport and brought back into service as a cost-cutting measure.
For 44 minutes after the blast, submariners Huntrod and McCann were trapped, along with stores accountant Richard Holleworth, while comrades tried to break open hatch doors which had buckled.
By the time a crowbar was used to get access, the two men were dead, while Mr. Holleworth had collapsed.
LOM McCann could have survived if he had been reached earlier, an inquest later heard.
Mr. Holleworth was already seriously hurt when he braved blinding smoke in a bid to save his two colleagues.
The 35-year-old told the inquest into his colleagues' deaths that the thought of his unborn son saved his life.
"My head was spinning and I was beginning to accept my fate," he said.
"I don't know how long I was sat there before I came out of the daze.
"I was sat on the floor holding his hand when I suddenly thought of my fiancée who was seven or eight months pregnant back at home. It was like a sudden bolt of rage smashing through. I thought he is not going to see his Dad.
"I remember shouting at Tony 'we have got to get on EBS or we are dead'."
Guided by the light of instruments, he staggered to an oxygen relay point and pulled on a mask. "All I remember is slumping to the floor. I accept that I must have just passed out."
He was roused 40 minutes later by the ship's crew attempting to breach the escape compartment.
His two colleagues could not be saved.
LOM Paul McCann, had submitted his notice to leave the Royal Navy having become engaged to his girlfriend in Philadelphia, America, not long before the tragedy.
A keen sportsman, he had represented both his home team and the Navy at cricket and played rugby for Plymouth Command and Old Halesowians.
Operator Maintainer Anthony Huntred, from Sunderland, had only been with HMS Tireless for nine months and had served in the Royal Navy for two years.
Following his death, his family said: "He will be greatly missed by us for the rest of our lives. He was over the moon when he joined the Navy.
"He greatly loved the Navy and the job that he did."
Not long before his death, he qualified as a submariner on board HMS Tireless, gaining the coveted award of the Dolphins badge.
Paying tribute to the young sailor, Commanding Officer of HMS Tireless, Commander Iain Breckenridge, said: "I consider myself fortunate and privileged to have worked with such a committed, capable and effervescent young man and it was rare that I talked to him without both of us breaking into beaming smiles.
"Anthony stood at the cusp of a successful career. His loss has been profoundly felt by all on board but our thoughts are very much with his family and friends to whom every man on board HMS Tireless passes his deepest sympathy."
LOM McCann, from Halesowen, West Midlands, was born on Christmas Day 1974 and joined the Royal Navy in November 2001.
He joined HMS Tireless in June 2004 and deployed to the North Polar Ice Cap on March 2, 2007.
He thrived on looking after the junior members of the ship's company and would always be available for advice, the MoD said.
His shipmates said he was considered a role model by his subordinates, who greatly appreciated his selfless participation and encouragement of their training.
In a tribute to LOM McCann, Cdr Breckenridge said: "He was simply the kind of man a commanding officer could call on at any time and in any circumstances – his exuberance, good humor and huge personality are greatly missed by all of his shipmates."
He was described by his mother Pauline, father Brian and sister Sharon as "a caring and gentle man who loved his family and was a great uncle to Indea and Lotte".
The Armed Forces Minister apologized after a coroner criticized the "systemic failures" which caused the explosion.
Bob Ainsworth admitted that "avoidable failings" brought about the blast on the Devonport-based attack killer after Sunderland Coroner Derek Winter criticized the Ministry of Defense’s handling of Scogs in his narrative verdict.
Almost 1,000 of the devices were recycled from a hazardous waste dump at Devonport and brought back into service by a civil servant as a cost-cutting measure.
"His decision was inappropriate," Mr. Winter said
No consideration was made to how they had been stored and their safety during that time, said the coroner.
While it was impossible to say whether the Scog which exploded was one saved from the dump, Mr Winter said it was a "significant possibility".
Scogs were not properly inspected, left in the open air, roughly handled and badly stored on board.
"There was a culture of complacency regarding the risks posed by Scogs and a tolerance of practices likely to increase those risks," Mr. Winter said.
He also criticized the decision to reissue the Scogs from the dump: "Those systemic failures led to the contamination and damage, in turn, caused the explosion."
Following the inquest, Mr. Ainsworth replied: "I would like to unreservedly apologies to the families, as I have done previously in the House and in person, for the avoidable failings, for which this department is responsible, which brought about this tragic incident."
During the seven-week inquest, it was revealed that Scogs were no longer in use on the British submarine flotilla.
After the verdict, Mr. Huntrod's mother, Brenda Gooch, said: "Two young men died through a lack of duty to care for their safety.
"The complacency across the whole chain of acquisitions, storage and handling is unforgivable to us."
Mother Pauline McCann said: "You can look at cost-cutting on some things, but not on life-saving equipment."
Seven submariners were honored with one of the Royal Navy's highest awards for their desperate attempts to save their crew mates.
They each received the Commendation of the Commander-in- Chief Fleet for their "outstanding response" following the incident.
The Navy did not release the names or ranks of those honored.
Following the tragedy, HMS Tireless' Commander Iain Breckenridge praised his crew.
Referring to Richard Holleworth's actions, he said: "In particular I would like to mention our crew member who was injured by the initial blast and thrown to the deck.
"He recovered himself, despite his injuries, placed an emergency breathing mask on his face and in complete darkness and zero visibility, due to the smoke, extinguished the numerous small fires in the compartment and allowed access to the firefighting and medical teams."
CDR Breckenridge added: "I am hugely proud of my entire ship's company who acted in a totally professional manner throughout, dealing with the incident calmly and to the highest standards you would expect of the service.
"Due to the training received and the whole team effort, the incident was contained and HMS Tireless was able to safely return to Devonport."
A Royal Navy investigation into the tragedy highlighted a series of failings regarding the use of Scogs.
A Board of Inquiry found the devices had been left on a jetty for weeks and returned to service despite being condemned.
The Royal Navy investigation also revealed that eight other problems were reported with Scogs during the Tireless deployment; seven misfired and one caught fire, emitting four-inch flames.
Other submarines had also reported problems.
HMS Superb reported a SCOG fire in June 2006 while Devonport- based HMS Trafalgar had two similar fires in October 2004.
A series of problems were also recorded between November 2003 and June 2006 including 12 misfires aboard HMS Torbay.
The inquiry also exposed how nearly 1,000 oxygen generators that had been condemned were returned to stock at Devonport after a visual inspection.
Tests carried out by NASA concluded that the explosion onboard HMS Tireless had most likely been caused by oil contaminating the generators.
Launched in 1984, Cold War warrior HMS Tireless was the longest serving nuclear-powered sub in the Royal Navy.
Tireless played a vital role in the Cold War for the majority of her service, used for coastal surveillance and for the protection of other submarines and ships.
She then was involved in various under ice exercises, and surfaced in the North Pole three times from 1991-2007.
In 2010, Tireless completed a 10 month deployment, the longest deployment made by a UK SSN at that time.
In 2014, the submarine was deployed to help locate the black box of Malaysian Airlines flight MH370.
She returned to HMNB Devonport for the final time on June 1, 2014, to be dismantled at Devonport Dockyard, where, at the time, 11 other nuclear submarines were waiting to be disposed of.
Commander R. Hywel Griffiths spent three quarters of his sea going career on board HMS Tireless.
During her decommissioning ceremony at HM Naval Base Devonport, He said: "She's been our home and our fighting platform; she is part of the family.
"I feel very attached to the ship's company, and we're attached by a camaraderie that's quite hard to explain.
"The most difficult part of our job is when the program changes and we get extended as we then have to explain that to our loved ones."

Australian Navy: Torpedo Firings on the Mark

Aiswarya Lakshmi, Marine Link
21 March 2017

AUSTRALIA – The Royal Australian Navy has tested its primary anti-submarine warfare weapon during Exercise OCEAN EXPLORER off the coast of Western Australia recently.
HMAS Melbourne, with the support of Collins class submarine HMAS Dechaineux, conducted three exercise firings of its MU90 torpedo.
Staff Officer Force Anti-Submarine Warfare Lieutenant Commander Chris Straughan from the Australian Maritime Warfare Centre embarked in Melbourne for the trial.
Lieutenant Commander Straughan said the torpedo was designed to counter any type of nuclear or conventional submarine. 
“The MU90 torpedo provides the Royal Australian Navy with one of the most capable lightweight torpedoes in the world. It is designed to detect and attack deep, quiet running submarines,” he said.
“The Australian Maritime Warfare Centre conducted the trials to test the performance of the torpedo against a live submarine.
“The results will be used to formulate new tactics, techniques and procedures.
“It is part of an ongoing weapons performance program that has been developed by the center as part of the Fleet Warfighting Strategy.”
The Navy continues to develop the MU90 capability in the fleet through regular tactical development activities against live submarines and acoustic targets.
That includes the world-first firing of a live MU90 torpedo by HMAS Stuart in 2013.
During the test, Stuart launched the torpedo at a specially designed submerged static target, positioned off the New South Wales south coast.
The Australian Maritime Warfare Centre is the Royal Australian Navy’s center of excellence for maritime warfare development. The center’s role is to optimize the war fighting effectiveness of the Australian fleet.
