This achievement is for unlocking the Asera Takatora in the Class I section.
Found a little trick to help save some time unlocking all of the Level 1 class ships. WARNING, if attempting this method, this should be the first thing you do before diving it anything else!
Load up the game and start Career Mode. Pick the ship needed to unlock achievement. Once Achievement is unlocked, go into Manage Game & Addons. Delete saved data from EVERYWHERE (hence why this should be done first). Sometimes you have to delete data from everywhere a second time before it deletes. Deleting just local save does not work as the game automatically restores save from cloud without any option to cancel save.
Boot game back up, and rinse and repeat with other ships needed for achievements.
