N'shaii mothership

The N'shaii mothership was a type of starship deployed by the N'shaii in the 23rd century.

The motherships were around ten-times larger than a Federation starship, and possessed weapons technology that outmatched Federation technology in the mid-23rd century, including a type of muon weapon which took a huge amount of energy to fire. The motherships could also deploy a series of satellites, would basically served as orbital weapons platforms, in orbit of a planet, which could serve independently, or be controlled by the mothership.

In 2257, the USS Constitution (NCC-1700) engaged a mothership that was attempting to subjugate the Federation member planet, Sordinia IV. Over the next eight years, additional motherships were encountered by the Federation starships USS Excalibur (NCC-1664), USS Lexington (NCC-1709), USS Potemkin (NCC-1657) and USS Defiant (NCC-1764) in orbit of various planets, including Velarrh VII, Mos'rammi IX, Indish III, Linyar II and Tenekratus IV.
