A simple question about skills

Here is a very simple question:

How can I achieve the skill "Fleet Tactics" ? I haven't found a
way to get it, it is not included in a cascade skill nor in
the skills tables.

P.S.: I only use the basic character generation ! Please tell me,
      if the skill is reachable only by the extended generation
      system.
