Which system is referred to by the acronym SLQ-32B?

The SLQ-32B refers to an electronic warfare system that is primarily used by naval forces to detect and counteract threats from anti-ship missiles. Its primary purpose is to protect ships from electronic threats, including missile guidance systems that may use radar or other forms of tracking. The SLQ-32B is equipped with electronic support measures (ESM) capabilities that allow it to gather intelligence on enemy radar emissions and identify potential threats. This system plays a critical role in providing situational awareness and enhancing the survivability of naval vessels in combat situations.

The other options do not accurately describe the SLQ-32B's function. While the system is involved in defense against threats such as anti-ship missiles, it is not classified as an anti-ship missile defense system in the more conventional sense, which typically refers to systems explicitly designed to intercept and destroy incoming missiles. Instead, it provides electronic countermeasures rather than direct physical interception.
