This supplement expands the Traveller roleplaying game with options for naval characters, whether serving aboard frontline warships or operating independently on aging freighters. It adds naval career paths and character-creation choices for military service. A revised starship-construction system supports the design of capital ships, fighters, and other vessels, with extensive options for weapons emplacements and additional systems. It also expands the rules for space combat and fleet operations.
