Minovsky Craft System
Since it is made up of charged particles, the I-field is unable to penetrate metal, water, the Earth's surface, or other electrically conductive materials and can be shaped simply by trapping it in an electromagnetic field. Thus, at low altitudes it is possible to generate an I-field cushion between the underside of a vessel and the ground, yielding a gravity-countering buoyancy. This principle is used in the creation of the Minovsky craft system, which allowed a spaceship or heavy ground vehicle to "fly"/hover on Earth. The Principality of Zeon was slow to make use of this principle and the only units equipped with Minovsky craft systems during the One Year War were the MAX-03 Adzam and the three prototype Apsalus mobile armours. However, the Earth Federation was quick to adopt the system on its Pegasus-class assault carriers. This allowed the Pegasus-class to enter and exit earth's atmosphere and to fly while inside the atmosphere.
