Sonobuoys equipped with an EFS system have what capability?

Sonobuoys equipped with an EFS (Enhanced Flight Support) system possess the capability of selecting channel, life, and depth settings. This ability enhances the operational versatility of sonobuoys by allowing operators to configure the devices based on specific mission requirements.

In practical applications, this means that the technician can determine how long the sonobuoy will remain active (life settings), the frequency channel it will operate on (channel selection), and the deployment depth (depth settings), which is critical for optimizing sonar performance and ensuring that the devices can adapt to various environmental conditions. This configurability helps improve the effectiveness of anti-submarine warfare operations by allowing for targeted data collection that matches the operational goals.

While other options may suggest functionalities that sonobuoys have, they do not fully describe the core capabilities associated with the EFS system in a way that prioritizes the mission-specific settings that technicians can modify.
