Rocket Lab Reports Neutron Stage 1 Tank Rupture During Qualification Testing

Rocket Lab Corporation, a global leader in launch services and space systems, has announced an update regarding the development of its Neutron rocket.

As the Company pushes Neutron to the limits and beyond to qualify its systems and structures for launch, qualification testing of the Stage 1 tank overnight resulted in a rupture during a hydrostatic pressure trial. Testing failures are not uncommon during qualification testing. We intentionally test structures to their limits to validate structural integrity and safety margins, ensuring that the robust requirements for a successful launch can be comfortably met.

There was no significant damage to the test structure or facilities. The next Stage 1 tank is already in production, and Neutron’s development campaign continues while the team assesses today’s test outcome.

The team is reviewing the Stage 1 test data, which will determine the extent of the impact on Neutron’s launch schedule. The Company intends to provide an update on the Neutron schedule during its 2025 Q4 earnings call in February.
