- For the ENT episode, see "Proving Ground".
A Proving ground, sometimes also referred to as testing ground, is a military location where personnel, weapons and similar technologies are tested.
In the 1940s, a proving ground was located in Nevada and was the site of the detonation of a nuclear weapon in 1947.
Quark, Odo, Rom and Nog later brought Quark's Treasure to the proving ground, where they flew into the nuclear explosion. (DS9: "Little Green Men")
Another Earth proving ground for nuclear weapons in the same era was located at the Bikini Atoll. (ENT: "Stratagem")
The Xindi maintained a proving ground in the Calindra system, where they tested a prototype for their superweapon in late 2153. (ENT: "Stratagem")
A region of space in the delta quadrant designated Subspace Munitions Range 434 was used for weapons tests by an unknown species in 2377. (VOY: "Human Error")
