You get a CV by leveling your crew. Up at the top of the main page under "Game Info" There's a heading called "Ship Tree. It will tell you what ship is available at what level and the path you must take to get to that ship.
It will also give you basic details about the various ships. It's ok to be new, even the people who are rude to you were noobs once. some of them not so very long ago.
That being said however, reading is your friend.
