Scheduled and dedicated launch service delivering cargo, satellites, and resupply payloads to low Earth orbit. From there our fleet of ships can forward that cargo to L4, Mars or anywhere in cislunar space.
LEO Cargo is Middleton Space's launch division — the workhorse that turns everything else the company does into a functioning supply chain. Our two-stage vehicles fly out of Gulf Coast Launch Complex and deliver commercial satellites, government payloads, and station resupply missions to low Earth orbit on a published, dependable manifest.
Every LEO Cargo vehicle is built at our L4 shipyard and rated for rapid reuse, which keeps launch cadence high and cost per kilogram falling year over year. Upper stages that reach orbit are recovered and refurbished at L4 rather than discarded, feeding directly into our Ship Building division's turnaround pipeline.

Book a slot on a scheduled LEO Cargo flight and split the cost of the ride with other smallsat and cubesat operators.
Recurring pressurized and unpressurized cargo runs to commercial and government orbital platforms.
Boosters and upper stages that reach orbit don't go to waste. Our Ship Building division inspects, refurbishes, and re-certifies flown hardware at the L4 Shipyard Facility, cutting the cost of every subsequent LEO Cargo flight.
