We printed this propellant less than 24 hours ago. We fired it today. Every motor tested at Firehawk is powered by propellant produced entirely in-house. In 2026, we will scale production to more than one million pounds per year.
In less than seven weeks, we designed, fabricated, and successfully static-fired a tactical RATO motor using our 3D-printed propellant.
Curious what chemical wizardry makes it possible to fire 24 hrs after casting. I’m assuming you’re bumping up the catalyst since you can get away with a shorter pot life when 3D printing propellant? I’d be shocked if inline mixing would work (think those 2 part epoxy guns). Probably would also need to tinker with curative as well. How does this impact cold strain mechanicals and aging over a 10-20 year service life?
Will Edwards - Really impressive! A lot of talk about scaling production capacity at speed. Great example of Firehawk actually doing it. Congrats to you and the team.
you badasses - Firehawk
Will Edwards amazing stuff!! Really thrilled for you and Firehawk!!
Absolutely incredible what is happening at Firehawk! Keep pushing !
Print Monday.Fire Friday.That's the cycle time the rest of the industrial base hasn't figured out yet.Great work to the team, Will!
Impressive to see something go from paper to a working prototype in just under two months!
Let's go Will! This is awesome! Congratulations!!
Speed, scale, and execution, are a beautiful combination. Congratulations!
Congratulations! This is where the defense industrial base conversation gets very real and exactly the kind of shift the industrial base needs. What stands out is not just the speed from print to fire, but what it signals operationally. In-house propellant production, rapid test cycles, and a path to scaled capacity all point to the same issue...defense manufacturing advantage is increasingly about how fast teams can move from capability to repeatable production. This is a meaningful shift! Excited to see what you do next.
