The Timeline at a Glance

Breeder construction Q2 2027, breeder first tritium ~2030, burner test unit ~2032, commercial fleet ~2036 — the plan, not a promise.

The sequence

MetroVolt sits inside a two-machine program. The breeder is built first because it delivers value on fusion gain alone; the burner follows once the breeder has retired first construction and operations risk. The dates below are targets from the current plan.

• Q2 2027 — breeder (Hyperion) construction begins.
• ~2030 — breeder first-of-a-kind first tritium.
• ~2032 — burner test unit (MetroVolt / Aegis core).
• ~2036 — commercial burner fleet.

Why these gaps

The years between milestones are not idle. Breeder construction and early operation feed magnet, cryogenics, tritium-handling, and controls experience directly into the burner. The burner test unit is designed and long-lead hardware ordered while the breeder runs, so 2032 is a build-and-test date, not a start-from-scratch date.

No MetroVolt performance claim precedes its test unit. There is no hardware net-gain claim before the breeder’s first-of-a-kind milestone, and no commercial burner claim before the 2032 test unit reports.
