The UNN 8th fleet was a United Nations Navy fleet that operated during the UN-MCR War.


Having been engaged against the MCRN 3rd fleet, the 8th fleet received heavy casualties but managed to destroy four battle groups of the MCRN fleet. 8th Fleet then consisting of 51 Destroyers moved towards Callisto where it would outnumber the MCRN fleet of 23 Destroyers.

The 8th Fleet was moving to try and capture or destroy the MCRN Callisto shipyards which were vital to the Martian war effort[1].
