The exposure is concentrated at Tier 3 and beyond in product value chains, where it is hardest to see and most difficult to remediate.
Since 2022, more than 849,000 commercial space industrial base imports have included exposure to components sourced from Chinese suppliers at Tier 3 or further upstream, Altana’s AI-powered illumination reveals. An additional 15,000 imports over the same period included exposure to Russian-origin components in their product value chains.
2026 has been called “the year of the space supply chain,” with unprecedented pressure from commercial mega-constellations and Department of War (DoW) programs competing for the same specialized components. And the space industrial base’s growing reliance on commercial companies — from launch providers to satellite operators to scores of smaller manufacturers — introduces supply chains that were built for commercial speed and cost efficiency, not for the kind of multi-tier visibility and adversarial screening that national security demands.

Adversarial exposure concentrates in the most critical space components

Altana’s analysis of 299 contractors, sub-contractors, and major suppliers in the U.S. commercial space industrial base reveals that adversarial manufacturing exposure is not distributed evenly across space supply chains. It is disproportionately concentrated in the components that are most essential and hardest to replace.
The upstream Chinese and Russian exposure uncovered by the analysis clusters around three categories of space-critical goods, which require specialized manufacturing and critical minerals over which China holds a global chokepoint.

Radiation-hardened electronics and semiconductor parts that enable high-frequency radar, satellite communication, signal processing, and spacecraft control, and are among the most specialized and sensitive components in the space supply chain. The affected parts include microcontrollers, integrated circuits, reprogrammable chips, printed circuit board assemblies, and electric accumulators. These components must withstand the extreme radiation environment of space, and the specialized manufacturing required to produce them is concentrated in a small number of global facilities with upstream ties to Chinese manufacturing.
Articles of vulcanized rubber engineered to withstand the extreme cold and heat of space, which are vital for vacuum stability, temperature resistance, and vibration dampening during launch and orbital operations. Affected parts include seals and gaskets that maintain pressure integrity in spacecraft systems, and protective coatings and adhesives that shield components from thermal cycling and radiation degradation.
Articles of iron, steel, and aluminum, including structural components like aluminum ducts and fasteners, as well as screws, bolts, nuts, and rivets. Space-grade metal components must meet exacting specifications for weight, strength, corrosion resistance, and performance under extreme conditions. Component-based tariffs on steel and aluminum content, combined with the adversarial upstream exposure identified in the analysis, could create compounding compliance and cost challenges for space contractors.

Taiwan semiconductor dependence adds a second axis of space industrial base vulnerability

The analysis also uncovers a parallel adversarial dependence: significant reliance on Taiwanese manufacturing for the advanced semiconductors that power space systems.
Since 2022, 26.8% of the commercial space industrial base’s semiconductor-related imports are from or have upstream exposure to manufacturers in Taiwan within the three most immediate production tiers, Altana’s analysis reveals.

This exposure is concentrated in the most advanced semiconductor products — radiation-hardened logic chips that control spacecraft, operate scientific instruments, manage power systems, and transmit data from Earth and deep space observations. Taiwan’s dominance in advanced semiconductor fabrication means that the most capable, space-qualified chips often trace back to Taiwanese foundries, even when the immediate supplier is based in the U.S. or another allied nation.
The geopolitical implications are stark. A Chinese ground invasion of Taiwan — a scenario that defense planners increasingly model — would not only disrupt the global semiconductor supply chain but would specifically compromise the production of the most advanced components that space systems depend on. Unlike commodity electronics, radiation-hardened space-grade semiconductors cannot be quickly sourced from alternative suppliers. Production requires specialized fabrication processes, extensive qualification testing, and years-long certification cycles.
For the space industrial base, the Taiwan dependence represents a different kind of vulnerability than adversarial manufacturing in China or Russia. Adversarial exposure creates compliance and security risks that can be mitigated by identifying and replacing upstream suppliers. Taiwan dependence creates a concentration and fragility risk — a single geopolitical event could simultaneously disrupt supply for hundreds of space programs, with no near-term alternative.
Space contractors and the DoW are asking:
  • Which specific programs and product lines have the highest concentration of Taiwan-sourced semiconductor content?
  • What is the current lead time to qualify alternative sources for radiation-hardened components, and how does that compare to the timeline of a potential geopolitical disruption?
  • Can the space industrial base and DoW partner to identify, in advance, which programs would be most impacted by a simultaneous disruption to adversarial and Taiwanese supply chains — and develop contingency plans for the most critical capabilities?

Scaling readiness and wargaming defense value chains with Altana

Defense agencies are already working to answer these questions and strengthen partnerships with industry by partnering with Altana to build a common operating platform for real-time collaboration between the DoW and the defense industrial base. This establishes a shared source of truth for the supply chains behind critical defense capabilities.
defense industrial base work
This effort to scale readiness and bolster national defense supply chain security is built on three capabilities:
  1. Illuminating the multi-tier defense supply chain network: Space contractors trace their multi-tier product value chains from finished systems back to raw material origins. Altana’s AI uncovers hidden relationships, dependencies, and risks — including upstream adversarial exposure that traditional supply chain tools miss. As relationships and risks evolve, the network updates dynamically, replacing static, point-in-time assessments with continuous monitoring.
  2. Facilitating collaboration between government and industry to strengthen supply chains: Defense contractors share verified supply chain data with the defense agency for evaluation. The defense agency assesses resilience and collaborates directly with companies to mitigate vulnerabilities — identifying alternative suppliers, flagging single points of failure, and ensuring that critical programs aren’t dependent on adversarial inputs. This public-private collaboration replaces fragmented, siloed efforts with a shared, collaborative picture.
  3. Stress-testing and wargaming to test readiness: Defense agencies use Altana to simulate the impact of conflicts and disruptions on defense supply chains — from an invasion of Taiwan to Russian aggression in Eastern Europe to the sudden loss of a critical sub-tier supplier. These exercises assess direct and cascading effects, such as dependencies, chokepoints, and geographic concentrations, allowing defense agencies and their commercial partners to mitigate vulnerabilities before they compromise operations.
