Space launch capacity requires input Launch vehicle2 evidenceEstablished relation
Space launch capacity depends on Launch vehicle.
Mechanism
Every orbital launch flies a licensed launch vehicle; capacity is vehicles available times cadence.

Upstream: what it depends on
Launch vehicle requires input Aerospace alloys2 evidenceEstablished relation
Launch vehicle depends on Aerospace alloys.
Mechanism
Tanks and structures are aluminum-lithium alloy, stainless steel or composites chosen for strength at low mass.

Launch vehicle requires input Rocket engine2 evidenceEstablished relation
Launch vehicle depends on Rocket engine.
Mechanism
Thrust comes from the engines on each stage; a vehicle cannot fly without its full engine set.

Launch vehicle requires input Rocket propellant2 evidenceEstablished relation
Launch vehicle depends on Rocket propellant.
Mechanism
Thrust is propellant mass flow times exhaust velocity; the vehicle is mostly propellant by mass at liftoff.
