U.N.S.S. Courageous (DY-500)
In 2022, the U.N.S.S. Courageous, a DY-500 class vessel under the command of Captain Fitzsimmons Wallabee, became the worst tragedy in the then-65-year history of space flight when a solar flare penetrated a flaw in the ship's shielding, sending the vessel on an uncontrolled course into interstellar space. The incident led to a design upgrade and new safety standards for all forthcoming ships.
