Underwater Warfare Suite Upgrade

New and Replace Existing Systems


To modernize the underwater warfare sensor suite that is currently installed on the Halifax Class frigates. The Underwater Warfare Suite Upgrade (UWSU) project will improve the performance of the underwater sensors through the upgrade and/or replacement of the components of the underwater warfare sensor suite.


The UWSU Project will reinstate a tactical advantage over threat submarines and torpedoes and gain improved survivability. UWSU will deliver an integrated system that replaces the current towed array sensor and sonobuoy processing system, adds additional active intercept sensors, and improves the processing and transmission control system of the existing hull mounted sonar. Additional components for the project will include a towed low frequency active sonar capability and a compatible active receive array that will improve detection performance for targets operating in both open ocean and littoral environments. The underwater warfare suite is to be designed in an integrated and modular fashion using commercial components and accepted open standards. The underwater warfare suite will minimize any physical changes to the current Halifax Class ship’s structure.
