Firehawk is targeting a defense-industrial bottleneck: its pages say conventional propellant mixing, casting and curing can take weeks, while its thermoplastic process produces feedstock in hours and its additive manufacturing cuts per-unit production times by more than 99%. Its $150M+ Series D is funding Lawton and Mississippi production capacity after a $60M Series C and Army/Air Force program traction, betting that scalable domestic propulsion production can replenish missile, rocket and artillery inventories faster.
