What kind of amenities are in submarines?

Submarines are equipped with a variety of amenities to support the crew's needs during extended missions. These typically include sleeping quarters, a galley for meal preparation, restrooms, and recreational areas for relaxation and entertainment. Advanced submarines also feature technology for communication, navigation, and monitoring systems, along with life-support systems to ensure air quality and water recycling. Space is limited, so amenities are designed to maximize functionality and comfort within confined quarters.
