At the dawn of 2402, Constellation Squadron ventured through the Barzan Wormhole to explore the depths of the Delta Quadrant and deepen diplomatic relationships with its denizens.  Led by the Constitution III-class explorer Constellation, Constellation Squadron was comprised of the Defiant-class escort, Meridian, the Dunderstadt-class fast cruiser scout, Minerva, and the Sutherland-class research cruiser, Almagest.

By April 2402, Constellation Squadron began scouting the Nacene Reach, where the USS Voyager encountered some of its fiercest antagonists during its voyage home in the 2370s.  Captain Taes received a one-way subspace message through a microwormhole, using Project Pathfinder technology.  The message from Fourth Fleet Command advised of subspace Blackouts inhibiting warp travel and long-range communication & sensors in seemingly random patches and zones all over the Alpha and Beta Quadrant.  And now, an army of the Vaadwaur Supremacy have pounced out of Underspace to attack and invade every civilization across both quadrants, including the Federation.

The orders for Constellation Squadron are to build alliances for the goal of repelling the Vaadwaur.  And Constellation isn’t alone in the Delta Quadrant.  Odyssey Squadron has received the same orders too.
