Neutron stage-1 tank fails during testing, pushing the debut to no earlier than Q4 2026
Rocket Lab's Neutron first-stage tank ruptured during a hydrostatic pressure qualification test on January 21, a setback that forces a delay of the rocket's first launch to Q4 2026. The carbon-composite tank failed during a routine structural test with no injuries or damage to the test facility.
- Test at Space Structures Complex in Middle River, Maryland; tank was tested to design limits.
- Another tank is already in production; Rocket Lab expects to provide updates during Q4 2025 earnings.
- First flight vehicle now targeted for Wallops Island pad in Q1 2026, with launch after qualification testing.
- Previous timeline: first launch late 2025; revised: no earlier than Q4 2026.
