Firefly Aerospace suffered a setback on its road to resuming launches with its Alpha rocket.<\/p>\n

During acceptance testing at its facility in Briggs, Texas, on Monday, the booster designated for Alpha Flight 7 \u201cexperienced an event that resulted in a loss of the stage,\u201d the company said in a statement.<\/p>\n

A spokesperson for Firefly said this acceptance test was taking place prior to the company shipping the booster to Vandenberg Space Force Base ahead of conducting a final static fire test and preparing for launch.<\/p>\n

A week before the incident, during the company\u2019s second quarter earnings call<\/strong> on Sept. 22, CEO Jason Kim said he expected Firefly to resume launches in the \u201ccoming weeks\u201d following a pause stemming from an in-flight anomaly seen during Alpha Flight 6<\/strong> back in April.<\/p>\n

\u201cWe received our [Federal Aviation Administration] Return to Flight determination at the end of August. We expect to launch Flight 7 in the coming weeks,\u201d Kim said during the call in response to Jeffries<\/strong> analyst Shelia Kahyaoglu. \u201cIf you saw our slides in the Alpha slide, you can see that Flight 7 is in a mature state, right next to Flight 8 in a mature state.<\/p>\n

\u201cAnd so we keep increasing our production capacity and we\u2019re building ahead as well for 2026. So we\u2019re working closely with the range and our customer, Lockheed Martin, to share more details on the mission and payload soon. But above all, safety and quality are the highest importance.\u201d<\/p>\n

An investigation<\/strong> into Alpha Flight 6 with oversight from the FAA and in parallel with an independent review board determined that the April anomaly was due to \u201cplume-induced flow separation intensified heat on the leeward side reducing structural margins, causing the booster to rupture from stage separation induced loads.\u201d<\/p>\n

Firefly noted in a statement last month that it would \u201cincrease the thermal protection system thickness on Stage 1 and reduce angle of attack during key phases of the flight,\u201d which it said had been implemented as of issuing that statement on Aug. 26.<\/p>\n

In response to questions from Morgan Stanley analyst Kristine Liwag during the earnings call, Kim said the corrective actions didn\u2019t require a change to the design of Alpha.<\/p>\n

\u201cThere is no change to the design. It\u2019s just adding more layers of the thermal protection system to the bottom of the first stage, and it\u2019s negligible in terms of mass,\u201d Kim said. \u201cThe second part of that question is, how does this change the angle of attack? We can control that at different phase, critical phases of the flight profile. And so that is something that we can plan for and can control as well.\u201d<\/p>\n

Alpha Flight 6 and Flight 7 are both part of a multi-launch contract between Firefly and Lockheed Martin, which would be up to 25 missions. The payload for Flight 7 hadn\u2019t been announced before the anomaly occurred.<\/p>\n
