A submarine tender is a type of support ship designed to provide logistical and maintenance assistance to submarines. These vessels are equipped with facilities for repairs, resupply, and crew support, ensuring that submarines can operate effectively while at sea. They often carry spare parts, fuel, and food, allowing submarines to remain deployed for extended periods. Submarine tenders play a crucial role in naval operations, especially during long missions. They can also serve as a base for training exercises and provide communication links between submarines and command centers. Their versatility makes them essential for maintaining the operational readiness of submarines.
