Destroyer escorts were small naval vessels designed to protect larger ships and convoys from enemy submarines and aircraft during wartime. They were equipped with anti-submarine weapons, radar, and sonar systems, making them effective in escorting merchant ships and providing a defensive screen for naval fleets. These ships played a crucial role during World War II, particularly in the Battle of the Atlantic, where they helped safeguard vital supply routes. Destroyer escorts were faster and more maneuverable than traditional destroyers, allowing them to respond quickly to threats while maintaining the safety of larger vessels like aircraft carriers and battleships.
