How did us battle German uboats in the war?

During World War II, the U.S. employed various strategies to combat German U-boats, including the use of convoy systems to protect merchant ships. Warships and aircraft conducted anti-submarine warfare (ASW) operations, utilizing sonar, depth charges, and aerial patrols to detect and destroy U-boats. The introduction of long-range bombers and improved radar technology also enhanced the U.S. ability to track and engage submarines effectively. Additionally, the development of the "Hunter-Killer" groups, which combined aircraft carriers and destroyers, played a crucial role in diminishing the U-boat threat in the Atlantic.
