reduces the life of the vehicle. The vehicle cost is one of the biggest
costs of launch, eclipsed only by R&D; and this scheme quadruples it
per unit payload (ok. rather less, as there are economies of scale.)
I fail to understand this piece. Launching 4x as often means you launch 4x as much payload per unit time,
No, because a similar sized LAP can only carry 1/4 the payload; so you only launch as much payload per unit time.
In fact I found an expendable LAP can only carry 1/4 the payload of an expendable TSTO of the same size/GLOW/dry mass.) A reusable LAP would be even worse.
