What do people on submarine eat?

People on submarines typically eat a variety of shelf-stable and frozen foods due to the limited storage space and long missions. Meals often include canned goods, freeze-dried items, fresh fruits and vegetables (when available), and pre-packaged meals that can be heated. Submarine crews also have access to a range of proteins, such as meats and fish, which are stored in freezers. The menu is designed to provide balanced nutrition while also considering the preferences of the crew.
