What This Means:
Starlab’s 2029 launch timeline rests on a supply chain that is now in active production — but the architecture beneath it carries concentration risks that program managers, investors, and competing contractors have not yet mapped. Vivace Corporation holds the single-source contract for Starlab’s primary structure, Leidos owns the only assembly, integration, and testing (AI&T) slot in the United States, and Airbus is the sole European design and engineering authority. Before NASA decides the fate of its Commercial Low Earth Orbit Destinations (CLD) Phase 2 award — a decision now in open flux as of May 2026 — executives with exposure to this supply chain should know where the single-thread dependencies sit.
The Signal That Started This
On February 23, 2026, Starlab Space LLC announced it had completed its Commercial Critical Design Review (CCDR) with NASA in attendance — the 28th milestone on the NASA Space Act Agreement, and the program’s definitive pivot from drawing board to production floor. The CCDR was not a press release milestone. It was a contractual gate: completing it positions Starlab to qualify for a milestone payment from NASA under the CLD program and formally transitions the program from design to manufacturing and systems integration.
That transition has teeth. Vivace Corporation, a New Orleans-based manufacturer, was already under contract before the CCDR closed. It had been tapped in September 2025 to build Starlab’s primary aluminum structure, one of the largest single spaceflight structures developed for launch in the commercial station era. By February 2026, Vivace had begun active production at NASA’s Michoud Assembly Facility (MAF), the same Louisiana facility that built the core stage for the Space Launch System’s Artemis II mission. The hardware clock is running.
The Supply Chain Map
Starlab’s architecture is a deliberate “best-of-class” assembly of proven aerospace integrators. That strategy creates a specific risk profile worth naming by tier.
Primary Structure — Vivace Corporation (Single Source)
Vivace holds the contract to manufacture Starlab’s primary aluminum structure at Michoud. There is no publicly disclosed backup manufacturer for this component. Based on publicly available disclosures, no alternative U.S. facility has been identified with equivalent capability and active clearance for a structure of this scale — though the existence of non-public contingency planning cannot be ruled out. Vivace’s production timeline is the critical path for every downstream integration milestone.
Assembly, Integration, and Testing — Leidos (Single Source, Alabama)
In November 2025, Starlab named Leidos as its primary AI&T provider. Leidos will assemble and integrate all station components, conduct environmental and performance testing, and provide safety and mission assurance — all at a single Alabama facility. There is no second AI&T source disclosed. Leidos also brings Dynetics, its defense-and-space subsidiary, into the integration architecture. The concentration of assembly authority in a single contractor at a single site is a program-execution dependency that carries no disclosed redundancy.
European Design and Engineering — Airbus Defense and Space (Exclusive Partner)
Airbus is not a minority stakeholder in Starlab’s design. It is the exclusive provider of technical design and engineering services for the station and co-owner of Starlab Space GmbH, the European subsidiary based in Bremen, Germany. The Bremen co-location places Starlab adjacent to Airbus’s International Space Station (ISS) Columbus Module infrastructure and the European Service Module team for NASA’s Orion spacecraft. For European Space Agency customers — and for any program that depends on European technical inputs — Airbus is the sole gateway.
