Ghost

Dream Chaser

A reusable lifting-body spaceplane that launches vertically (Vulcan Centaur, folding wings inside a 5 m fairing) and lands on a conventional runway at less than 1.5 g. The cargo configuration can carry 5,000 kg pressurized and 500 kg unpressurized, with an expendable Shooting Star module adding cargo, power, and disposal. First vehicle Tenacity is planned for a late-2026 free-flyer from Kennedy to Vandenberg rather than an ISS docking. A crewed version remains a later product.

LIFE habitat

Large Integrated Flexible Environment, an inflatable softgoods habitat that launches packed in a 5 m fairing and inflates on orbit to a three-story, ~285 m3 pressurized volume - about one-third of the ISS in a single launch. Built from high-strength webbings and fabric with an air barrier, restraint layer, and MMOD/MLI blanket. Full-scale ultimate burst-pressure tests at NASA Marshall in 2023-2024 are the main structural qualification evidence. LIFE is Sierra's habitation contribution to Orbital Reef and is also offered as a standalone module family (including smaller LIFE 10 configurations).

Orbital Reef

Commercial mixed-use station in LEO co-led with Blue Origin, with Boeing, Redwire, and others as partners. Sierra provides LIFE habitats, node modules, and Dream Chaser transport; Blue Origin provides core infrastructure, power/thermal mast, and New Glenn launch. NASA posted CLDC solicitation 80JSC027R0004 on Oct. 9, 2026. As of Oct. 28, 2026, neither Sierra Space nor Blue Origin has said Orbital Reef will be proposed. A stated plan to compete would not be an award.

Eclipse satellite buses

A three-class satellite bus line - Horizon (proliferated LEO, missile warning/tracking), Velocity (high-delta-V, RPOD, refuellable), and Titan - used as the production chassis for Sierra's SDA Tracking Layer work. Horizon is the bus for both the 18 Tranche 2 vehicles (structures complete) and the 18 AMDT3 Golden Dome satellites.

New Glenn

Blue Origin

Heavy-lift orbital launch vehicle with a reusable first stage, designed for commercial, civil, and national security missions.

New Shepard

Blue Origin

Suborbital launch vehicle for space tourism and research, capable of fully autonomous vertical landing and reuse.

BE-4 Engine

Blue Origin

Liquid oxygen/liquefied natural gas (methane) rocket engine - the first American-made oxygen-rich staged combustion engine. Powers New Glenn and ULA Vulcan Centaur.

Blue Moon

Blue Origin

Lunar landing system family with a cargo-focused Mark 1 variant and a crew-capable Mark 2 variant being developed for NASA's Artemis program.
