Rocket Lab delays first Neutron launch
Posted: Sun, Mar 1, 2026, 12:03 PM ET (1703 GMT)
Rocket Lab is pushing back the first launch of its Neutron rocket to late this year. The company said in an earnings call Thursday that the rupture of a propellant tank during testing last month will delay the first flight of the rocket to at least the fourth quarter of the year. Rocket Lab said a manufacturing defect in the composite tank caused it to rupture during a hydrostatic pressure test, noting that the company had expected the tank to pass the tests. The company is producing a replacement tank using a new automated system rather than the hand-laid process used for the first tank, and is also making minor design changes to the tank. Before the test failure Rocket Lab expected to have the first vehicle on the pad this quarter but had not set a launch date. Rocket Lab added in the call that it continues to see strong demand for its Electron small launch vehicle, including a contract with BlackSky for four launches
