The Chor-class shield generator is a fixed based Klingon technology structure present on Klingon Empire colonies.
History and specifications[]
They play a pivotal role within a colony as it increases the shield strength of friendly forces. A set region is protected by the energy field allowing defensive weaponry to be placed in more important locations. The shield generator is power hungry mainly because of inefficient Romulan components being used. (ST video game: New Worlds)
