In addition to the XO, which position is responsible for signing the NAVSUP 1359?

The position responsible for signing the NAVSUP 1359, which is the "Subtender Financial Management Report," is indeed the Food Service Officer (FSO). This individual plays a crucial role in overseeing the financial management of food services within a unit, ensuring that all expenditures and financial practices align with regulations.

The FSO is directly involved in monitoring and managing the budget for food service operations, which includes reviewing expenditures and ensuring that all transactions are properly documented. The NAVSUP 1359 is a key document in understanding and analyzing the financial aspects of food service operations, making the FSO’s signature necessary to validate the information contained within it.

While the other positions may have their own responsibilities, they do not hold the specific authority or responsibilities related to the financial oversight of food service operations like the FSO does. Therefore, the FSO is the correct choice for who would sign the NAVSUP 1359.
