The 10th Fleet is responsible for the Navy's cyber warfare programs and is subordinate to which commands (for space issues)?

• A. CYBERCOM only
• B. STRATCOM only
• C. TRANSCOM
• D. CYBERCOM and STRATCOM

Answer: (D)

The important idea here is how cyber and space operations are commanded in the DoD. Cyberspace operations are led by CYBERCOM, while space operations fall under STRATCOM. The 10th Fleet, as the Navy’s cyber warfare force, must coordinate with CYBERCOM for cyberspace activities, and with STRATCOM when space-related issues are involved because space operations influence and are influenced by cyber actions. That dual relationship—being connected to both CYBERCOM and STRATCOM for these domains—best explains why the 10th Fleet is said to be subordinate to both commands for space-related concerns. The other options don’t fit because they imply oversight by a single command or involve a different combatant command that isn’t the focus for these domains.
