The present invention relates to a high-speed sealift system which meets the requirement of the 21st century. In the 21st century, the indispensable requisites for a commercial sealift system that is to be deployed across the five oceans are high speed and stability. The present invention relates to a high-speed sealift system which operates at the super-high speed of 40 knots to 70 knots, and which is capable of the marine transport, in a quick and safe manner, of perishable goods, expensive capital goods, goods the volume or weight of which result in them being incapable of being transported via the air, strategic military goods, and capable of the large-scale redeployment of forces, and particularly, parts or equipment and materials which require a timely arrival. The sealift system of the present invention operates by means a marine transportation principle in which elevation force, found from Newton's law of physics that indicates that “the change of momentum of a body is proportional to the impulse impressed on the body,” is applied to tires. When a planning gear of the high-speed sealift system is lowered to enable tires to contact water at a speed higher than a predetermined threshold speed, the elevation force corresponding to the distribution weight of the system is generated at the contact surfaces of the tires, such that the system travels on the water at the travel speed of the tires. That is, the transportation effects of the system are the same as those achieved when a vehicle travels at a high speed on a highway with the tires thereof on the ground. According to one embodiment of the present invention, in which a 2000 ton high-speed sealift system is designed in accordance with the marine transportation principle of the present invention, the system is propelled by two 55,000 horsepower water jet pumps when traveling at a maximum high speed of 65 knots, while a total of 80 tires including 16 front tires and 64 rear tires support the weight of the system on the water at a speed of 5 knots or higher by planning components.
