Supremacy concentrates risk that Nebula distributes

Supremacy concentrates political leadership, fleet support, hundreds of thousands of personnel, and docked warships in one enormous target. Its destruction becomes a strategic single point of failure rather than merely the loss of one combatant. A viable fleet would need several such support ships instead of one irreplaceable centerpiece, but building that class would also advertise hostile intent to the New Republic. A viewer compares the signal to Brazil suddenly building Yamato in 1910: the disproportionate scale would itself announce a strategic challenge. The Nebula class offers the contrasting design, with centerline and aft-firing batteries that provide coverage in several directions. Missiles, close-in weapons, fighters, and a manageable crew make the Nebula a more balanced and repeatable unit of fleet strength.
