The invention provides various aircraft carriers, warships, submarines and offshore platforms with efficient load-eliminating swing-stopping capsizing-resisting correction devices. Load-eliminating self-balancing swing-reducing devices, load-eliminating floating air bag
cushion devices, externally-suspended weight-adjustable balancer devices, correction plate and wing-type swing-reducing plate devices, devices for accelerating floating and diving of the submarines, self-balancing control devices for accelerating
underwater hovering, devices for horizontally pushing whole ship hulls to quickly shift to arrive at or depart harbors, safe quick-decelerating and quick-lagging electric
propeller devices and top magnetic-field
inertia moving weight balancer devices are provided. The aircraft carriers, the warships, the submarines and the offshore platforms have the advantages that according to the structures, swings, in
six degrees of freedom, of ships, the warships, the aircraft carriers and the offshore platforms can be solved comprehensively, sailing ship hulls are timely and safely protected from sudden obstacles, perfect and efficient swing-reducing systems are formed, several major problems in the field of navigation ships are solved, balance stability and safety of aircrafts and
spacecraft in the field of the ships, the aircraft carriers, the submarines or
aerospace are improved, capability and confidence of human beings in control of offshore or aerial activities are greatly improved, swing reduction is changed into swing stop, and the aircrafts never lose their balance and fall down.
