<p><a href="https://www.linkedin.com/in/will-edwards/"><u>Will Edwards</u></a>, CEO &amp; Co-founder of <a href="https://firehawkaerospace.com/"><u>Firehawk</u></a> walked around defense conferences with what was essentially Lego plastic demonstrating it could become rocket fuel. Everyone laughed until Firehawk proved thermoplastic works as a binder for 3D-printable solid propellant, cutting production from 60 days to 6 hours. The breakthrough came from a failed pivot: they tried selling hybrid rocket engines to disrupt the supply chain, but learned the military won&#39;t swap proven systems for new architectures. Success required replicating solid motors exactly, just manufactured differently. </p><p>Will also explains why missile startups without propellant production will fail and why comparing defense manufacturing to SpaceX misses the point: primes already produce thousands of complex systems annually, they&#39;re just constrained by cast-and-cure physics, not capability. </p><p><strong>Topics discussed:</strong></p><ul><li><p>Using thermoplastic binders to 3D print solid rocket propellant, cutting production time from 60 days to 6 hours</p></li><li><p>Why hybrid rocket engine disruption failed and success required replicating solid motors with different manufacturing physics instead</p></li><li><p>How traditional cast-and-cure propellant production constrains scale through 5,000-pound batches requiring hundreds of molds before curing</p></li><li><p>Why missile startups without propellant production capacity will fail competing against Northrop and L3Harris manufacturing queues</p></li><li><p>Debunking SpaceX comparisons in defense: primes already produce thousands of systems annually, constrained by physics not capability</p></li><li><p>Scaling from thermoplastic fuel experiments to 200,000 base bleeds annually and 10,000 rockets monthly by 2028</p></li><li><p>Designing only for systems requiring 300,000+ units annually to ensure meaningful defense production impact at scale</p></li><li><p>Building distributed propellant manufacturing in Europe and Indo-Pacific regions to match Ukraine artillery consumption rates  </p></li></ul>
