Directrix - Galactic Patrol Z9M9Z - GFHQ

Designed to be the Command and Control ship for the entire Galactic Patrol this gigantic tear-drop ship was technically the Z9M9Z, socially referred to as the Directrix and ordinarily performing as Grand Fleet Headquarters (GFHQ)

This ship possessed no armaments but had every defensive system then known to the Galactic Patrol.

Central to it's role as Grand Fleet Headquarters was a holographic tank over 200 meters in diameter that modeled the entire galaxy as well as the location and status of over a million combat units. Over 200 Rigellians were used, because of their inate sense of perception, to track individual fleets.

It was first employed in the englobement and destruction of the Boskone Galactic Director Jalte base in a globular cluster outside of the Milky Way.
