I'm not implying that the CVN has a chow line running 24/7, but if the cereal on your ship was consumed in a week, then your SUPPO needs to be buying more cereal. PB&J and other sandwich type items are also easy options. Regardless of what ship anyone is operating from, the last thing Sailors & Aircrew need to be worried about is being hungry while they're working 18 hour days. This should be a priority for leadership, hence my original comment. If there's a food smuggling ring on a ship, then the S-2 Division is broken and the CO needs to fix it.
I agree. None of this seems like a real issue. Look no farther than 7th Fleet, and we can all see a shining city upon a hill that is premiere leadership. Also, they absolutely shine at figuring out True Wind*, so figuring out food planning should be a cake walk. As long as the cake isn't moist.
And those that have operated from an Aviation Capable Ship (like you, Brett) will no doubt agree that the crew is getting food at meal times, even the aviation department, because there are meal options. The fact that pilots don't necessarily operate at those same times that the aviation department is getting said meals is probably a non-issue.
Those that say there are some ships that operate in environments where they don't have the firepower of a fully operational aircraft carrier and where food costs significantly more than "normal," and can't just "buy more" are probably just eating too much. If the rest of the fleet is getting food, they are probably an outlier.
*They don't.
