Y-500 class
From Memory Alpha, the free Star Trek reference
The Y-500 class freighter was a vessel that was used during the 21st century. It was equipped with life pods. Y-500 class freighters were in service by 2088 and retired several decades prior to 2151. (ENT: "Strange New World")
It is unclear if the Y-500 class was a predecessor or successor to either the DY-500 class or the Y class.
