Who is responsible for the Navy's cyber operations?

The U.S. Fleet Cyber Command is the organization responsible for the Navy's cyber operations. It oversees Navy cybersecurity missions and is tasked with ensuring the security of naval networks and the execution of cyber warfare operations. This command plays a critical role in defending against cyber threats, providing support for naval operations, and enabling the Navy to achieve its objectives in cyberspace.

In contrast, the Naval Information Warfare Center focuses on developing and delivering information warfare capabilities and technologies, which supports cyber operations but does not oversee them. The Office of Naval Intelligence is responsible for intelligence and does not directly conduct cyber operations. Meanwhile, the Naval Sea Systems Command is primarily focused on the engineering, building, and maintenance of naval ships and submarines, which does not encompass the specific domain of cyber operations. Thus, the U.S. Fleet Cyber Command is identified as the sole entity in charge of cyber operations within the Navy.
