That is because they have to interpret what they hear to determine what is occupying the waters surrounding their vessel; particularly if that “what” may be an enemy submarine. With 2020 marking the 75th anniversary of the Battle of the Atlantic, Sonar Operators today continue to be the core of naval anti-submarine warfare.Developed in the early 20th century, and initially used for anti-submarine warfare at the latter part of the First World War, sonar became a cornerstone for convoys by allowing them to detect enemy submarines during the Battle of the Atlantic. Ally convoys were under constant threat and often attacked by U-Boat “Wolf Packs”, and early detection of enemy submarines often meant the difference between crucial supplies and personnel reaching Britain or being lost to the sea.“Being a sonar operator means I have to always be looking beyond,” says Petty Officer First Class Joseph Rempel, Senior Sonar Operator in HMCS Ottawa. “You have to set yourself up for success. Know where you think the submarine is and if you locate it, be able to anticipate its movements to track it.”A small specialized trade, sonar operators (SonarOps) are employed in both the Halifax-Class frigates and Victoria-Class submarines, with the majority working in the surface fleet. All SonarOps receive the same core occupation training, but approximately one or two choose to complete submariner training following their basic qualification course. In the end, the work is similar, but the environment is extremely different.“The initial trade course for a SonarOp is approximately four months and focuses on acoustic analysis, oceanography, and...
