In 2366, in an alternate timeline, USS Enterprise-D weakened the deflector shields of an attacking Klingon K'vort-class warship by using dispersal pattern Sierra. The dispersal pattern involved launching five photon torpedoes simultaneously. The torpedoes spread out mid-flight and struck the target nearly simultaneously from multiple angles. (TNG: "Yesterday's Enterprise" ) In 2372, USS Voyager used dispersal pattern Sierra when firing photon torpedoes at a Kazon carrier vessel. (VOY: "Basics, Part I")
