Firefly Aerospace lifted its Alpha rocket from Space Launch Complex 2 at Vandenberg Space Force Base at 5:50 p.m. PDT on March 11, 2026, achieving orbital insertion and deploying a Lockheed Martin technology demonstrator. The mission, dubbed “Stairway to Seven,” marked a clean return to flight for the small‑lift vehicle after a prior anomaly.
The launch validated several key Block II upgrades, including a new in‑house avionics suite and an enhanced thermal protection system. Alpha performed a stage‑two engine relight, confirming the reliability of the upgraded propulsion system. The current vehicle measures 96.7 feet in length; the Block II configuration slated for Flight 8 will extend the rocket to approximately 104 feet.
Firefly’s successful flight underscores its growing track record in responsive launch services and strengthens its position in the U.S. defense and commercial satellite markets, where timely deployment is critical. The mission also demonstrates the company’s ability to meet contractual obligations with Lockheed Martin, a key customer that represents a significant portion of Firefly’s launch revenue.
"Alpha Flight 7 was flawlessly executed with all mission requirements completed, further proving the resiliency, innovation, and passion of the Firefly team. Over the last several months, we took a hard look at our processes across engineering, production, test, integration, and operations and invested the time required to make a series of improvements to ensure a higher level of quality and reliability in every Alpha we deliver and launch as we move to our Block II upgrade," said CEO Jason Kim. "Flight 7 served as a critical opportunity to validate Alpha’s performance ahead of our Block II upgrade, and this team knocked it out of the park. I’m incredibly proud of the Firefly team for continuing to define perseverance. We have full confidence in our Alpha rocket, and we’re committed to continuous improvement as we roll out Block II. We want to thank Space Launch Delta 30 and our customers for their ongoing collaboration and support," added Vice President of Launch Adam Oakes.
Investors responded positively to the launch, reflecting confidence in Firefly’s reliability and its ability to secure future contracts in the defense and commercial satellite sectors.
