A "ship-towed long-range acoustic detection system" is also commonly referred to by its acronym, SLADs. Another synonym for this technology is the "underwater acoustic sensor system," which is used to detect and track submarines or other underwater vehicles. It can also be called a "passive acoustic system" due to its reliance on detecting sound waves emitted by underwater vehicles. Additionally, SLADs can be categorized as a type of sonar, and may be referred to as a "sonar array system." Finally, it may be referred to as a "marine acoustic detection system" due to its specific application in detecting underwater threats.
