The role of Ohio

The advanced "sea seal" transportation system designed by the US military aims to make the "sea seal" commandos stay in a relatively good environment during the process of carrying out special tasks from submarines to the target coast without having to soak in cold seawater for a long time. The advanced "Sea Seal" transportation system, also known as "Sea Seal" transport ship, is a kind of miniature submarine, which is specially used for the transportation, delivery and recovery of special forces. It uses an advanced silent propulsion system with two crew members, and can secretly transport or withdraw a "seal" special operations team. The captain19.8m, the diameter is 2.44m, the weight is 55t, the underwater displacement is about 200t, the speed is 8 knots, and the voyage is125th nautical mile. The mast is equipped with photoelectric sensors, which can capture night scenes and transmit these images to the command department through data links. The advanced "Seal" transport system is small in size, but it has the joint operational command and communication system equivalent to the "Los Angeles" class nuclear submarine, a small periscope and a multifunctional sonar with navigation, mine detection and collision avoidance functions. In addition, there is a hyperbaric oxygen chamber at the stern for saving lives.
