The weapons control and torpedo compartment of Enterprise NX-01, the domain of Lieutenant Malcolm Reed, where the ship's torpedoes were loaded and its phase cannons controlled.
The armoury is the weapons centre of Enterprise NX-01 and the usual post of its tactical officer, Malcolm Reed, when he is not on the bridge. It is a two-level compartment with torpedo launch tubes, racks of spatial torpedoes and consoles for targeting.
The room is central to Silent Enemy, in which Reed and Tucker hurry to build and install the ship's phase cannons there after an attack by an unknown enemy, and nearly overload the ship in testing them. During the 2153 refit the armoury takes on photonic torpedoes, and in the third season the MACOs train alongside Reed's security staff.
It is also where Reed runs his drills and where his meticulous, security-minded character is most often shown, in episodes such as Singularity and Minefield.
