Australian Collins Class Submarines to Receive Sonar Upgrades

 Navy’s Collins Class submarines will undergo significant upgrades to its sonar systems here in Australia through a multi-million dollar contract with Thales Australia.

The two contracts, worth around $23.7 million, are for the design and implementation of the Mine and Obstacle Avoidance System and the High Frequency Intercept Array for the submarine fleet.The upgrades will not only enhance the capability of the Collins Class fleet but will provide a boost to Australian Defence industry and support Australian jobs.Minister for Defence, Senator the Hon Linda Reynolds CSC said both the Mine and Obstacle Avoidance System and High Frequency Intercept Array are important parts of the upgrades to the Collins sonar system.

“Our six Collins Class submarines are a highly capable and regionally superior capability that are only halfway through their operational life,” Minister Reynolds said.“To ensure this capability maintains its edge, we are upgrading and improving its systems including through sonar upgrades.

“The purpose of a Mine and Obstacle Avoidance System is to acoustically detect obstacles, including mines, which pose a threat to the submarine. The High Frequency Intercept Array detects high frequency noises including sonar transmissions.“With more than 20 years of investment in Australia by Thales and Defence, these upgrades will complement broader improvements to the sonar capability of the Collins Class, ensuring the regional superiority of the fleet into the future.

“Because of this Government’s action, we have a Collins Class submarine that is now exceeding the Royal Australian Navy’s availability requirement.”Minister for Defence Industry Melissa Price said Thales had extensive experience working on the Collins fleet and other Australian-based companies would be engaged throughout the contracts.“These contracts will include about 80 per cent of work being completed by Australian industry,” Minister Price said.

“We can expect these contracts to support 30 new jobs with Thales Australia in Rydalmere, NSW and additional jobs along the supply chain – jobs that will continue throughout the contracts.“Once again, we are backing Aussie businesses and creating jobs in our defence industry, which is in turn helping the national economy on its road to recovery after COVID-19.”

NSW Minister for Jobs, Investment, Tourism and Western Sydney, Stuart Ayres said, “Thales Australia has a long history of supporting the Royal Australian Navy with sonars, periscopes and other electronic systems proven with the fleet at sea.“The sonar systems developed by Thales Australia represents a major contribution to an enduring sovereign sonar capability for the nation.”

Japan Moves Ahead with JNAAM co-Development

As part of its fiscal year (FY) 2021 budget, the cabinet of Japanese Prime Minister Yoshihide Suga on 21 December approved plans to move ahead with the co-development of a Joint New Air-to-Air Missile (JNAAM) with the United Kingdom.Specifically, Japan’s Ministry of Defense (MoD) has secured JPY1.0 billion (USD9.7 million) to fund development costs related to the trial production of a prototype of the JNAAM, an MoD official confirmed during a 21 December press briefing.

The joint programme transitioned to a prototype stage in FY 2018 and is expected to finish trial production of the prototype during FY 2022, according to MoD documents. Following this, the two countries will evaluate the performance of the missile and then decide whether to put the weapon into mass production.The current joint Japan-UK research project, initiated by the two nations in 2014, is scheduled to conclude by the end of FY 2023, which is March 2024 in Japan.Janes understands that the UK missile technologies included in the programme relate to MBDA’s Meteor Beyond Visual Range Air-to-Air Missile (BVRAAM).

On the Japanese side, the MoD is looking to integrate advanced radio frequency (RF) seeker technologies developed by Mitsubishi Electric Corporation for the AAM4B missile, with the aim of enhancing the accuracy and performance of the BVRAAM and supporting the development of the JNAAM.A Mitsubishi Electric Corporation spokesperson in Tokyo declined to comment to Janes on specifics of the programme, noting that, “it is normal for the company not to refer to any national defence projects”.
