To conduct intelligence and sabotage missions in hostile territory, naval commandos utilize various infiltration methods from the sea, including the latest generation of underwater propulsion systems, known as the 3rd Generation Underwater Propulsor (PSM3G). This system is deployed using a removable deck hangar, also referred to as a Dry Dock Shelter (DDS), which is equipped on nuclear submarines.

This innovative floating board enhances infiltration capabilities for combat swimmers, providing a new means of access to enemy territory.
