Firehawk Raises $150M+ Series D for U.S. Propulsion Capacity

General Dynamics Ordnance and Tactical Systems is putting a specialist propellant manufacturer inside a larger artillery business. Its partnership with Firehawk Defense brings the Texas company’s manufacturing process together with the prime contractor’s metal-parts and munitions-integration capabilities, giving Firehawk a commercial route from material science into ammunition supply.

Firehawk announced a Series D of more than $150M on October 28, 2026, at a post-money valuation above $1.4B. Advent and Rochefort Asset Management led the financing, which will fund manufacturing and integration expansion, additional R&D sites and headcount. For the Dallas-based propulsion company, the capital supports an industrial growth assignment: develop more capacity while its products advance through the customer programs that could eventually use it.

What Firehawk’s Series D finances

The new capital is directed toward Firehawk’s production facility in Lawton, Oklahoma, and its integration facility in Crawford, Mississippi. Those are different stages of the same business. Making propellant, building a motor and integrating a complete rocket each leave the company with a different relationship to the eventual customer, along with another set of operating responsibilities.

Firehawk’s current facility description identifies the Great Plains Arsenal in Lawton as a 320-acre energetics site, with capacity of up to 3.1M pounds of propellant annually at full-rate production. The Mississippi campus is presented as an integration operation that can support 40,000 tactical rocket systems annually, with a ramp to 120,000 at full rate. These are company-stated capacity figures; they describe the scale being built rather than a record of accepted shipments.

The financing brings Advent International and Rochefort Asset Management into the next expansion phase as co-leads. Firehawk also said new and existing investors and strategic partners participated, without naming the rest of the Series D roster. The size of an individual investor’s contribution and a complete lifetime financing total were not disclosed in the announcement.

DevCuration’s coverage of Re:Build’s U.S. manufacturing expansion follows a related industrial question: how capital supports the journey from engineering a product to producing it. Firehawk brings that question into propulsion, where the prospective buyer also has a say in the evidence a supplier must produce.

A process designed around the production schedule

Firehawk describes a thermoplastic process that makes energetic feedstock in hours and allows that material to be stored before it is shaped into application-specific propellant grains. Compression molding, extrusion and 3D printing are among the forming methods. The useful commercial idea is flexibility between producing the material and committing it to a particular application.

That distinction matters when discussing manufacturing speed. The hours-long claim concerns feedstock production, one stage within a much larger system of fabrication, assembly, testing and customer acceptance. A buyer’s replenishment schedule ultimately depends on the output of that whole chain. Firehawk’s funding gives the company more resources to connect the stages in facilities it is expanding.

Founder and CEO Will Edwards leads the business, with Dominic Jezierski listed as CTO in Firehawk’s leadership material. A historical company announcement identifies Ronald Jones and Steve Edwards alongside Will Edwards as co-founders. The company’s development from propulsion technology toward manufacturing and integration makes organizational depth relevant: the work now includes turning an engineering method into repeatable industrial operations across sites.

The company’s engineering story therefore travels with its operating story. Adding equipment and staff changes how much of that process Firehawk can carry inside its own organization.

The prime contractor relationship has a defined scope

General Dynamics Ordnance and Tactical Systems announced the teaming agreement on May 4, 2026. It covers development and production of next-generation 155mm base bleed motors and establishes an exclusive arrangement focused on Direct Commercial Sales opportunities. That specific scope gives a clearer picture of the business than a loose reference to a defense partnership.

GDOTS described Firehawk’s contribution as thermoplastic propellant formulations and molding capabilities, combined with its own metal-parts production and munitions-integration experience. The division of work connects a specialist manufacturing process to an established ammunition supplier. For an industrial startup, that route can place the product inside a customer offering whose other components and integration work already belong to a larger organization.

The relationship also changes what scale means for Firehawk. A process improvement has to remain useful after it crosses the boundary between the specialist supplier and the prime contractor. Read in that context, the Series D finances more than another stretch of product development: it supports the manufacturing organization behind a particular commercial handoff. Investors are backing the capacity to participate in that handoff repeatedly as the companies pursue the opportunities covered by their agreement.

An Army program puts numbers on supplier development

The U.S. Army’s August 5 account of its Hydra-70 awards names Firehawk alongside iRocket, Nammo Perry and Albers. Each vendor is to deliver 24 prototype Hydra-70 M151 High Explosive rockets and a modernized technical data package within 18 months. The stated goals include additional production sources, competitive pricing and improved manufacturability, with follow-on agreements planned after successful prototype demonstrations.

Firehawk separately reported six successful Hydra-70 live fires in August, using rockets built at its Crawford facility. The company said the testing collected flight data ahead of inspection and acceptance milestones. That puts the test in its proper place within supplier development, where useful early data can support the work still required by a government program.

Other defense manufacturers are attracting capital for production as well, including Castelion’s hypersonic manufacturing expansion. Those companies address different products; the shared topic is the industrial capacity behind the defense system.

The financing follows a $60M Series C that closed in September 2025, according to Firehawk’s latest announcement. The new investment now joins a much more concrete set of obligations: expand the facilities, grow the team, support the prime relationship and deliver the Army prototype package. Firehawk’s factory planning and its customers’ qualification calendars are becoming parts of the same operating conversation, with propulsion capacity taking shape through the work those customers can evaluate.
