The outcome of the Fifth Frontier War will be decided by the clash of battle fleets and the capture of worlds, but fleets do not operate in isolation. Escorts, scouts, logistics ships and raiders all play their part. It may be that a heroic convoy defence or a daring raid could tip the balance of a fleet engagement. A crucial mote of intelligence gained or interruption of communications might provide an opportunity to win a decisive victory or avoid crushing defeat.

War Fleets of the Fifth Frontier War presents the doctrines of the Third Imperium and Zhodani Consulate and details warships from both sides of the conflict, from battleships to covert operations vessels and third-line warships of the Imperial Colonial Fleet. With deckplans and notes on variants, roles and deployment, any of these ships can be the focus of adventure.
