Dual-Unit & Fleet Siting

Two or more separated Aegis units at one installation deliver redundancy and let capacity grow in steps.

More than one, deliberately

Given the availability gate, the smallest resilient Aegis deployment is two units, and larger installations site a small fleet. Multiple units provide the N+1 margin, allow one unit to be maintained while the others carry load, and let generation scale with the installation's mission over time.

Separation and layout

Units are separated so that a single external event or internal fault cannot take more than one. Separation is physical (distance, protective structure) and functional (independent cooling, control, and fuel handling). The distribution bus is arranged so that any unit can feed any critical load path, avoiding a single tie that would undo the redundancy.

• Minimum resilient deployment: two units
• Physical + functional separation between units
• Bus arranged so any unit can serve any critical feeder
• Capacity added in unit-sized steps as mission grows

Phased growth

Fleet siting supports phased capacity: an installation can begin with the units it needs and add more without redesigning the microgrid. Each added unit improves both capacity and the redundancy ratio, so continuity strengthens as the site grows.

The staging is bounded by the program timeline — a test burner around 2032, commercial units around 2036 — so early fleets are small and grow as the design matures and the helium-3 supply chain scales. Because each unit forms and shares the bus by local droop control, a two- or three-unit site keeps running through the loss of any one machine with no operator intervention, which is the behaviour that turns a set of moderately available units into a continuously available installation.
