The space ruled by the Imperium is divided into five fleet zones known as the Segmentae Majoris. The galaxy is such a vast place that it would be unmanageable without this system.

帝国统治的空域被分为五个舰队区域，称为主要星域。银河系是一个如此广阔的地方，如果没有这个系统，它将无法管理。

Overview 概述

Each Segmentum has its own Imperial Navy and Merchant Fleets, as well as a Segmentum Fortress or Segmentum Naval Base that forms the base of fleet operations within the Segmentum. The Segmentum fleet commanders are known as the Lord High Admirals. The Segmentum Fortress is controlled directly by a high-ranking official of the Administratum known as the Master of the Segmentum.

每个星域都有自己的帝国海军和商船舰队，以及一个星域堡垒或星域海军基地，构成星域内舰队行动的基地。星域舰队指挥官被称为领主至高海军上将。星域堡垒由一位被称为星域之主的内务部高级官员直接控制。

Although intended for purposes of fleet administration and shipping controls, the Segmentae have evolved into administrative divisions of the Adeptus Terra.

虽然星域旨在用于舰船管理和航运控制，但它已经演变为中央政务部的行政部门。
