Rocket Lab identifies carbon composite structures as critical bottleneck; Neutron uses world's largest flying carbon composite structure, requiring intensive ground testing at novel architecture
Peter Beck· Rocket Lab· Space· 2025-11-14· about Rocket Lab (RKLB)
“the vehicle itself is let's not forget is the world's largest flying carbon composite structure ever built... Every one of Neutron's major structures are tested on the ground to the levels that exceed what the rocket may see in flight”
Why it matters
Neutron's use of carbon composites at unprecedented scale creates supply chain risk and testing intensity. The novel 'Hungry Hippo' fairing and suspended second-stage architecture require custom composite layup and qualification.
Investment implication
Suppliers of advanced carbon composite materials, autoclave equipment, and structural testing systems (e.g., MTU Aerospace, Solvay, Hexcel, or specialized aerospace composites firms) face increased demand and quality requirements. This may constrain availability for other aerospace programs.
