What is the primary purpose of the SLQ-25C system?

The primary purpose of the SLQ-25C system is focused on torpedo countermeasures. This system is designed specifically to protect naval vessels from torpedo threats by employing a variety of techniques. The SLQ-25C utilizes towed decoys that simulate the acoustic and magnetic signatures of a ship, thereby drawing hostile torpedoes away from the actual vessel. This functionality is critical for maintaining the safety and operational effectiveness of naval ships in combat situations where torpedo threats are a significant concern.

The other options presented do not align with the primary function of the SLQ-25C. While anti-ship missile defense, long-range radar detection, and communications enhancement are important aspects of naval warfare and defense systems, they do not pertain to the core capability of the SLQ-25C, which is dedicated to torpedo defense.
