The quote comes from StarCraft, Blizzard's 1998 real time strategy game, where the Battlecruiser is the Terran faction's most powerful capital ship. Clicking to build one triggers this confirmation line from its captain, signalling the vessel is ready to deploy. Because Battlecruisers were expensive late game units, hearing the phrase meant a major force had arrived. The line stayed popular with strategy players and editors long after release, reused in gameplay videos, remixes, and reaction edits whenever something massive is about to launch.
