Did World War 2 submarines have freezers?

World War II submarines generally did not have freezers as we know them today. They relied on limited refrigeration systems to preserve perishable food, but these were not as effective as modern freezers. The primary method for food storage was salting, drying, or canning, which allowed submarines to manage food supplies during long missions. The technology and space constraints of submarines at the time limited their ability to maintain a frozen food supply.
