What is the primary function of the AN/SQQ-89 Undersea Warfare/Anti-Submarine Warfare Combat System?

The primary function of the AN/SQQ-89 Undersea Warfare/Anti-Submarine Warfare Combat System is to detect and localize underwater threats. This combat system is specifically designed for underwater warfare, enabling naval forces to identify, track, and engage submarines and other submerged targets effectively.

By leveraging a combination of sonar systems and data processing capabilities, the AN/SQQ-89 allows operators to gain situational awareness in the underwater domain, which is critical for maintaining dominance in maritime operations. The successful execution of anti-submarine warfare relies on the ability to accurately locate and assess threats, making this function central to the system's purpose.

In contrast, the other options do not align with the core capabilities of the AN/SQQ-89. Aerial surveillance is not a function of this system, as it is focused exclusively on underwater threats. Control of surface-to-air missile systems pertains to entirely different systems focused on air defense, while enhancing logistical support relates to supply chain management and operational support, which are not direct functions of an anti-submarine warfare system.
