collecting rare fighters, maybe spoiler

[vahadar]

So far in my game i'm able (since day1) to purchase the Trident and Hrimthurs T, i'm still waiting to see the Gunslinger on Charon market. I've redocked many time there but still only the 2 first ship available. I guess they must be some trigger later in game to unlock the last 2.
My pilots are now aces but i dont have them displayed yet, i am just after the precursor mssion in the storyline.
