Purchase a ship from a Shipyard. In order to use this function, a ship under your agent's ownership must be in a waypoint that has the Shipyard trait, and the Shipyard must sell the type of the desired ship.

Shipyards typically offer ship types, which are predefined templates of ships that have dedicated roles. A template comes with a preset of an engine, a reactor, and a frame. It may also include a few modules and mounts.
