Aschelan V was a planet located near the Demilitarized Zone. It was the location of a Cardassian fuel depot.

In 2370, B'Elanna Torres reprogrammed the Cardassian missile Dreadnought to destroy the depot on Aschelan V. However, the missile again failed to reach its target, as one day after its launch it was swept into the Delta Quadrant by the Caretaker. There, it locked onto the similar planet Rakosa V, mistaking it to be Aschelan V. (VOY: "Dreadnought")
