Australia's Defense Materiel Organization has signed a contract with Thales Australia to upgrade the Collins Submarine Platform Training Simulator. "By adopting the latest Thales simulator technology, the upgrade will incorporate improvements to the PTS to address obsolescence and fidelity issues, bringing it up to date with the current configurations of the actual submarines," a statement from Thales said. "This contract is a prime example of how we work closely with the customer to deliver low-risk, cost-effective upgrade solutions that will enable the navy to continue to train their Collins crews for many years," Thales Australia Chief Executive Chris Jenkins said. Australia plans to decommission the Collins class vessels by 2025 and has started procurement for the next generation submarines. The Thales win comes after the navy announced that its recently acquired amphibious ship Choules suffered technical problems that halved propulsion power.
