Reuse only pays if the vehicle was designed for the second flight before the first. Vector's structures carry 40% fatigue margin over a 25-flight life, the engines come off only at overhaul, and the legs are inspected where they stand. What lands on Tuesday is vertical on a transporter-erector the following Friday.
The result is a launch cadence that behaves like a schedule instead of a lottery — and a vehicle whose 32nd flight costs us less than its 2nd did.

Figures are Block 4, fully reusable configuration. Expending the booster adds roughly 22% to LEO mass and is priced accordingly — we would rather have the booster back.
