WASHINGTON - Firefly Aerospace is proudly announcing that it's building rockets at an all-time high, which is great, except for the small detail that actually launching them remains a bit of a bottleneck. In an Aug. 11 earnings call, executives boasted that production of its Alpha launch vehicle is at an 'all-time high' while development of its larger Eclipse vehicle proceeds apace, all to meet what they describe as overwhelming commercial and government demand for space access.
'I can't stress enough that the demand for launch capacity is amplified right now. We've never seen launch capacity so constrained,' said CEO Jason Kim, who apparently has never met a constraint he couldn't amplify. 'That not only helps the demand for Alpha, but also for Eclipse.'
The company is cranking out Alpha rockets, which can hoist up to one ton into low Earth orbit. 'We have so much hardware on the floor. The production is at an all-time high, so that gives us really, really high confidence that we're going to continue to pump out Alphas at rate,' Kim said. And indeed, the hardware is piling up like laundry - but the launches? Not so much.
Alpha has flown exactly seven times since September 2021, with the most recent mission in March, a return-to-flight effort after an April 2025 failure. That's a launch rate that would make a sloth proud. The company is also working on an upgraded Block 2 version, which stretches both stages and improves subsystems. In May, Kim said Flight 8 would be the first Block 2 launch, scheduled for 'late this summer.' Now, in this call, Flight 8 has slipped to the fourth quarter, and the company plans just one more launch after that this year, down from the two it projected in May.
As for 2027, Kim was characteristically vague: 'A majority of our manifest for 2027 has already been sold out,' he said, but declined to specify how many missions that actually means. 'We're not going to talk about guidance for 2027,' he added, because who needs transparency when you have confidence?
The launch lag has real consequences. In October 2024, Firefly won a contract from True Anomaly for three responsive launch missions, starting with the Space Force's Victus Haze. But True Anomaly's Jackal spacecraft ended up launching in May on a SpaceX rideshare instead. Kim said the contract remains in place, with the Alpha launch 'saved for a later date per the Space Force direction.' So the rocket is ready, but the mission will wait.
On the brighter side, Lockheed Martin extended its contract with Firefly on Aug. 11, allowing it to run through 2031, though it doesn't add to the previous maximum of 25 launches. That's 15 firm launches plus options for 10 more - a lot of hardware to sit on the floor.
Meanwhile, Eclipse, the medium-class vehicle developed with Northrop Grumman, is progressing. 'We're just heads down right now on our Eclipse program,' Kim said, including qualification of the Miranda engine. They recently fired it for 226 seconds in a mission-duty-cycle test. But when will Eclipse actually fly? 'No earlier than 2027,' Kim said, which in rocket time might as well be 'eventually.'
Kim emphasized that Eclipse 'is going to unlock a lot of launch capacity in the future,' but Northrop will handle marketing for government work, including on-ramping onto the Space Force's National Security Space Launch contract. 'We're just working toward our first launch, showing the capability because, at the end of the day, what matters most is delivering the payload to the mission orbit that we sign up for, and that's what we're focused on,' he said. Because, you know, actually launching is kind of the whole point.
