Firehawk targets a defense-industrial bottleneck: legacy propellant casting and curing can take up to two months, while its additive and thermoplastic process is described as reducing per-unit production time by more than 99% and enabling production in hours. Its more-than-$150M Series D, led by Advent and Rochefort Asset Management, is funding the Lawton production and Crawford integration facilities as the company scales output for U.S. and allied munitions supply chains.
