Which feature is associated with the SLQ-25C system?

The SLQ-25C system, also known as the Nixie, is specifically designed for torpedo countermeasures. Its main function is to protect naval vessels from underwater threats, particularly torpedoes, by deploying a towed decoy that creates various acoustic signals to mislead enemy torpedoes. The decoy simulates the sound of the ship, drawing the torpedo away from its intended target. This capability is crucial for enhancing the survivability of a ship during naval operations.

While submarine detection could seem relevant due to the underwater context, it is not a primary function of the SLQ-25C. Furthermore, ballistic missile defense and cyber defense capabilities do not relate to the SLQ-25C's design or purpose, as these focus on different aspects of military operations and technologies outside the scope of the system's torpedo countermeasure function.
