Collect 10 Ships
To unlock this achievement, you need to have collected 10 spaceships cumulatively, regardless of whether you currently own all of them or have sold some. Once you've acquired and interacted with a total of 10 spaceships over the course of your gameplay, you will meet the requirements for this achievement.
To unlock the Fleet Command achievement you need to acquire 10 spaceships. The good news is you don’t have to own all 10 simultaneously, and even sold or stolen ships count towards your total.
From the story and four Faction Questlines, you will automatically acquire three ships:
You will likely buy a fourth ship during the storyline, because you will need a ship with a 21 Lightyears Jump Distance to complete a story objective, and none of the above ships meet that requirement.
After securing quest-related ships, you'll need to acquire an additional six to seven ships.
Use the approximately 1,000,000 Credits earned from the Story and Faction Questlines to buy more ships from Ship Service Merchants located at the landing pads of all major cities.
Opt for the most affordable ones, priced around 100,000 credits each, to ensure you can purchase the number you need.
Feel free to sell ships you no longer want to Ship Service Technicians, who will offer 20% of the original purchase price. Remember, sold ships still contribute to your 10-ship total.
In case of a cash crunch, stealing ships is a valid option. Unregistered stolen ships count towards the achievement, providing an alternative method for completing your collection.
