A type of mine known as a lift-mine incorporated internal repulsorlifts, allowing it to levitate above a planet's surface. These lift-mines possessed the capability to either maintain a fixed hovering altitude or oscillate between two specified heights. Advanced models, such as the DR-X55 manufactured by Norsam, were capable of identifying approaching enemy vehicles within a one-hundred meter radius and altering their elevation to collide with the target.
