Submarine loading refers to the process of loading cargo or materials onto a submarine, typically for military or research purposes. This can involve specialized equipment and techniques due to the confined space and unique operational requirements of submarines. The process must be carefully managed to ensure the safety and efficiency of the submarine's operations. It is essential for missions that require stealth and underwater capabilities.
