Donatu V

Donatu V, known in Klingonese as Dona'tu vagh, is the inhabited fifth planet in the Donatu system of the Beta Quadrant.

Ownership of Donatu V, as well as the rest of the surrounding region, was disputed between the United Federation of Planets and the Klingon Empire from the point of first contact, through the mid-2250s.

The Battle of Donatu V, one of the few battle fought between the Federation and the Klingons during their Cold War, was fought here in 2245. The battle was inconclusive.

In 2374, during the Dominion War, the Jem'Hadar destroyed three convoys destined for this planet.
