Rocket Lab's Neutron Rocket Suffers Fuel Tank Rupture During Test

Rocket Lab's Neutron rocket stage ruptured during a hydrostatic pressure test in Wallops, Virginia, on Jan. 21.

The incident marks a setback for the company's ambitions to compete in the commercial launch market. The test, conducted to validate structural integrity and safety margins, resulted in a total loss of the stage but caused no serious damage to facilities or surrounding structures.

"We intentionally test structures to their limits to validate structural integrity and safety margins to ensure the robust requirements for a successful launch can be comfortably met," the company stated.

The rupture occurred during a non-destructive testing protocol, indicating the failure was unintentional. The debut launch, originally targeted for Q1 2026, now faces an uncertain timeline.

Rocket Lab plans to update investors on the Neutron schedule during its February 2025 Q4 earnings call.

The rocket is designed to carry 28,700 pounds (13,000 kg) to low Earth orbit and features reusable first-stage ocean barge landings. The company has not disclosed specific technical details about the rupture or immediate corrective measures.
