Thales has signed a $100 million design and pre-production contract to upgrade Collins class submarine sonar systems. The company will enhance the system’s capability to outperform the most advanced underwater threats in an increasingly complex environment.

Thales will build on its local and international expertise to prepare for upgrades to the  cylindrical array, flank array, and on-board processing on the submarines, to maintain Royal Australian Navy superiority in the region.
