Who is the Responsible Officer for fuel onboard CVN ships?

• A. Supply Officer
• B. Stock Control
• C. S-1F
• D. The V-4 Division Officer

Answer: (D)

The key idea is who is accountable for aviation fuel on a CVN. On these carriers, fuel support is handled by the aviation department, specifically the V-4 division. The V-4 Division Officer is designated as the Responsible Officer for fuel onboard, meaning they have the authority and responsibility for all aspects of aviation fuel—receiving, storage, transfer, quality control, safety, and coordination with flight operations. This specialization ensures proper procedures, safety, and compliance in handling a critical resource for aircraft operations.

The other roles cover broader or different areas: the Supply Officer oversees overall supply, not the day-to-day fuel operation; Stock Control focuses on inventory accuracy; S-1F is part of the supply organization but not the designated RO for fuel. Thus, the V-4 Division Officer is the appropriate person for fuel on the carrier.
