Time-limited - Uncommon ships - put on sale from time to time.Ships have different availability for various reasons, set by CIG: To purchase ships using real currency, see: Pledge Store Availability The third option includes access to Star Citizen with the ship purchase. The second option replaces a ship that is currently on an account with a more expensive ship while charging only the difference in value between the two ships. The first option results in a ship being added to an existing RSI account, but it does not give access to Star Citizen (this makes it most useful for existing backers).
Pledge ships can be bought as standalone purchases, as ship upgrades, or with game packages. These purchases help fund the development of Star Citizen and Squadron 42. Ships purchased with cash are called ' Pledges' and are permanently attached to your Star Citizen account. Ships in Star Citizen may be purchased either with in-game currency ( aUEC) or with real cash.
