The LI'wI-class colony ships were a type of starship used by the Klingon Empire in the 24th century.
Normally, the Klingon people expanded through conquest, however, there were those occasions when a dedicated ship tasked with creating new colonies was necessary which was the goal of the LI'wI-class. They were capable of landing onto a new world and their modular construction allowed them to be stripped for parts in producing an outpost for the colonists. Their non-combatant role required them to be escorted to their target. (TNG video game: Birth of the Federation)
