Why Astra

Three things a program office needs, in one supplier.

[ SOVEREIGN & ITAR ]
Domestic supply chain

Every engine and vehicle is designed, built, tested, and manufactured on U.S. soil. Full ITAR compliance and supply-chain sovereignty for sensitive missions, with no foreign dependency.

[ RESPONSIVE ]
Tactically responsive access

Mobile, minimal-infrastructure launch designed for short-notice, on-demand deployment from austere or forward locations, in support of tactically responsive space.

[ MISSION ASSURANCE ]
Proven, qualified hardware

A 100% on-orbit propulsion record and disciplined, repeatable manufacturing built for scale, backed by qualification testing and configuration control.

Capabilities

What we bring to the mission.

Domestic manufacturing
In-house production in Alameda, CA, built to industrialize space-qualified hardware with traceability and repeatability.
Mission assurance
Category-class launch mission-assurance posture and a perfect on-orbit propulsion reliability record.
