The Imperial Navy
Overview: The Imperial Navy is one of the armed forces employed by the Imperium. While the Imperial Guard is responsible for the Imperium's ground forces, The Imperial Navy is responsible for the fleets of warships that soar between the stars and planets in the Imperium as well as engaging threats both inside and outside the Imperium's borders. The Imperial Navy is split into several fleets. These fleets generally have the task of safeguarding the sector after which they are named, for example Battlefleet Gothic will be protecting the Gothic Sector. The fleets are usually made three distinct types of ships: battleships, cruisers and escorts. Battleships are huge ships, with enormous amounts of weapons and shields, and are usually the command position for the Admiral of the Fleet. Although very powerful, battleships are slow to maneuver. The majority of a fleet will be comprised of cruisers. Though not as powerful as a battleship, cruisers are much faster and can still deliver a deadly blow. There are several different types of cruiser, including those that are specialized towards destroying heavily armoured targets, and those that have large fighter bays along their sides. Escort ships are the smallest type of ship in the Imperial Navy star fleets. They can usually be seen traveling in squadrons of 3 to 5, though larger squadrons are not that uncommon. The main task of the escort ships is to draw fire away from the capital ships so that they can get into position quickly and safely.
