The LHA contains twenty high ground gravity beam generators positioned just under the outer skin of the hull. Each is capable of projecting a small interdiction field, dampener field, or emitted a focused beam of gravity or anti-gravity. The result is that the system can provide a varety of functions including a .5au radius interdiction field, a dampening field of similar size, or up to twenty directed interdiction/dampening beams. The gravity put out by this system also acts as the ship’s form of STL propulsion.
