The Sovereign-class employs sixteen phaser arrays at key locations throughout the ship's hull. Seven dorsal phaser arrays are located on the primary hull, one extending around the saucer section, giving it an oval appearance. Six smaller arrays cover the aft dorsal firing arcs and are located along the aft portion of the saucer section, above the main shuttlebay. Four ventral phaser arrays are located on the primary hull, extending around in nearly a half circle on both the starboard and port ventral sides of the saucer section. A single phaser array is located along the ventral section of the engineering hull, running perpendicular to the hull. Four line the trailing edges of the warp nacelle pylons (one dorsal and one ventral for each pylon).
