Aegis is the defense housing of the D-3He burner: the shorter central-cell configuration, sized to the fuel that will exist when it is built, and configured as a fixed-site generator for defense installations rather than a shipboard plant.
Aegis applies the burner's reference physics in a shorter central cell: same D-3He mirror, same closure gates, same direct-conversion train. Because length sets machine size at little cost to closure, the defense housing is simply a shorter cell than the data-center housing, carrying the same physics and the same helium-3 fuel dependency.
A fixed installation values resilient power that arrives without a fuel convoy. Aegis is pitched as installation energy against delivered-fuel logistics — a comparison that favors it — and never as a propulsion-cost argument, which it would lose.
