===Retooling===
A shipyard has to have the appropriate equipment and supply chain to construct a ship and all of its components, and this is represented in Aurora by the Retooling cost. Each shipyard's slipways are geared toward production of one class of ships at a time, and retooling for a new project takes considerable time and resources. This can get very expensive if you change your tooling often.

Properly planning your fleet construction can save you time and costs. Note that it is possible that other ship classes can be built in the same shipyard without retooling. For a second class to qualify as eligible for construction, it must be possible to refit a ship of the primary class to that class for less than 20% of the primary ship class cost.

''See the "Priorities/Misc" (C#) or "DAC/Rank/Info" (VB6) tab in the [[Class Design]] window for eligible secondary classes.''

To begin Retooling, go to Shipyard Complex Activity, "Task Type" and select "Retool". The class selected for retooling is chosen from the adjacent ship class dropdown. Only classes that are small enough to fit within the shipyard's capacity can be selected. A brand new shipyard (one without a class assigned) may be retooled for free and no time, otherwise this task costs 0.5x of the ship class build cost plus 0.25x ship class build cost per slipway. So if a shipyard with two slipways wanted to start building a class that cost 800 BP, the cost to retool would be <code>800 x (0.5+0.25+0.25) = 800</code> BP. If there were four slipways, the cost would be <code>800 x (0.5+(0.25x4)) = 1200 BP</code>. Mineral use is based on the minerals used in the class.
