Orbital Reef

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).

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.

Ghost

A deployable-decelerator reentry vehicle for returning cargo from orbit, or from high altitude, to a precise landing site. Sierra pitches it as a pre-staged orbital supply node with a five-year on-orbit life and a 90-minute delivery to anywhere on Earth. Unveiled in April 2024. In May 2026 two Ghost vehicles were dropped from 35,000 ft and 68,500 ft at Dugway during U.S. Space Command's Apollo Nexus exercise, recovering a software-defined radio and liquid cargo. AFRL's REGAL study, awarded October 2024, is meant to scale the 150 kg payload class toward 5-10 tonnes.
