The Premise

The pad is the constraint. So remove the pad.

Orbital launch has always been tied to a handful of fixed, expensive sites. Bee-SL applies the Cretus premise to orbital access: design for the logistics that already exist.

A conventional transport aircraft carries the vehicle to altitude and releases it. The runway becomes the launch site, and the aircraft becomes the first stage.

Mission Profile

Runway to orbit, in four moves.

The aircraft does the work a first stage normally does: it lifts the vehicle clear of the dense lower atmosphere, then lets go.

Released at altitude, the bundled vehicle ignites and climbs on its own.

Payload Delivery

The final stage does the delicate work.

Once the spent cores fall away, the Bee-SL upper stage coasts to its target orbit. The fairing opens, the payload clears the stage, and the satellite is set free.

Fairing separation

The nose fairing splits away and exposes the payload above the atmosphere.

Deployment

The satellite separates from the stage and begins its mission.

Ignition

The same core, bundled and lit.

Bee-SL does not need a bespoke engine program. It is built from the same Bee cores as Bee-MX, bundled into one vehicle and fired together.
