The Shipyard Screen contains a list of available Ships with pictures and descriptions. It will say after the ship's name the number of ships currently on the planet. The cost of the ship, as well as the amount of time it will take to build are shown under the description. You can build additional ships by entering the number of ships you want to build of each type and the pressing send at the bottom of the page.
Unlike buildings, and technologies, ships in production cannot be cancelled.
Defensive units and ships are both manufactured by the Shipyard and share the same production queue.

It will show a resource in Red if you do not have enough of that particular resource. It will also tell you how long you will have to wait at current mine production before you can build that unit.
