Firehawk Defense Closes $150 Million Series D at $1.4 Billion Valuation to Mass Produce Rocket Motors

For most of the last two decades, the American solid rocket motor industry has rested on a very small number of suppliers. Two legacy prime contractors, L3Harris and Northrop Grumman, dominate the production of the energetic materials that power everything from shoulder-fired rockets to intercontinental ballistic missiles, an arrangement that made sense in peacetime but has looked increasingly fragile as demand for tactical munitions surged.

That demand has been driven by sustained artillery and rocket expenditure in Ukraine and the Middle East. Stockpiles held by the United States and its allies have been drawn down, and replenishment orders now stretch across Europe, the Middle East and the Indo-Pacific, according to Rochefort Asset Management. The result is a procurement environment in which volume, speed and a second or third source of supply matter as much as technical sophistication.

Into that gap has stepped Firehawk Defense, a Dallas-based propulsion and energetics manufacturer that launched in 2019 as a builder of hybrid rocket engines powered by 3D-printed fuel and has since expanded into solid propellant, artillery motors and complete rocket systems. The company argues that the incumbent industrial base was built for a different era: optimized for large strategic motors, produced slowly, in modest numbers and at high unit cost.

Firehawk's alternative is a continuous thermoplastic process. Instead of mixing and curing propellant over a period of weeks, the company molds propellant into the solid fuel cores of motors within hours. That single change underpins an ambitious production plan, and it is the reason investors have now priced the startup alongside far more established names in the defense sector.

Key Facts

Firehawk Defense said on October 28, 2026, that it closed an oversubscribed Series D of more than $150 million at a valuation above $1.4 billion. Reuters reported on October 28 that the round was co-led by private equity firm Advent International and Kyle Bass' Rochefort Asset Management, with new and existing investors and strategic partners also taking part.

The raise was upsized. Defence Blog reported on October 29 that the Dallas Morning News put Firehawk's original target at $100 million. Rochefort said in its own release on October 29 that it co-led the financing alongside Advent, and that the firm operates under a license from the U.S. Department of War's Office of Strategic Capital. The step up in valuation is steep. Firehawk raised a $60 million Series C in September 2025 at a valuation of $290 million, and Tectonic Defense reported on October 28 that the new round represents a large jump from that mark, roughly a fivefold increase in headline value in about a year. Earlier backers include 1789 Capital, the venture capital firm backed by Donald Trump Jr.

Production plans are concrete. Firehawk expects to produce more than 100,000 artillery motors in 2027 under a commercial agreement with General Dynamics Ordnance and Tactical Systems, starting with sales to allied nations while it runs a 12 to 18 month qualification process for the U.S. Army. By the end of 2027, it expects to be the largest producer of artillery motors in the United States and the third largest producer of rocket propellant by weight in the country.

The capital funds two sites. The 320-acre Great Plains Arsenal in Lawton, Oklahoma, broke ground in April and is expected to commission in early 2027, producing 740,000 pounds of thermoplastic propellant a year with installed capacity scalable beyond 3.1 million pounds. The company has said the site will produce roughly 3 million pounds of propellant annually by the end of next year. In Crawford, Mississippi, a facility of more than 600 acres is already operational and can integrate about 40,000 small-diameter rockets a year, with a stated goal of roughly 120,000 at full-rate production.

The company has grown from 22 employees in 2022 to 150 today, and its customers include the U.S. Army, the U.S. Air Force and major defense contractors. In August 2026 it fired six Hydra-70 rockets at Yuma Proving Ground in Arizona and all six worked as intended, a six-for-six result that followed a U.S. Army Other Transaction Authority award. The Army has also selected Firehawk as one of four new companies to build Hydra-70 rockets.

Analysis

What this really means is that the binding constraint in Western munitions production has moved. For years the bottleneck was understood as factory floor space and machine tools. Firehawk's pitch suggests the real constraint was process chemistry: the weeks-long mix and cure cycle that legacy manufacturers inherited from a Cold War production model and never had a commercial reason to abandon.

The company's technical claim is a compression from a 60-day process down to six hours, as chief executive Will Edwards described it to Tectonic Defense. If that claim holds at scale, the economics of solid rocket motor production change in two ways at once. Working capital tied up in curing inventory falls, and the marginal cost of adding volume drops, because a continuous line can be run harder without a proportional increase in floor space or headcount.

Firehawk has also chosen its market segment deliberately. It is focused strictly on high-volume, small-diameter munitions under 13 inches: 155mm artillery base-bleed motors, rocket-assisted take-off motors and 2.75-inch Hydra-70 rockets. That is terrain the primes have largely left alone. Aerojet Rocketdyne and Northrop Grumman concentrate on larger rockets, Edwards told D CEO Magazine, which leaves room to manufacture smaller systems at high volumes and lower costs.

The strategic logic is visible in the products themselves. Base-bleed motors attach to the base of standard artillery shells and burn a small amount of propellant to cut aerodynamic drag, extending range by up to 30 percent according to Reuters, or up to 35 percent by the company's own account. The Hydra-70, an unguided rocket, is increasingly paired with laser-guidance kits to serve as a low-cost interceptor against aerial drones, a role that has become far more valuable since 2022.

Why It Matters

The bigger picture here is a deliberate attempt to recreate competition in a market that had quietly consolidated. The Pentagon has spent years warning that a two-supplier base for solid rocket motors is a single point of failure, and that warning became operational reality when demand for artillery and rocket motors outran what the existing handful of suppliers could deliver. Firehawk is not merely adding capacity. It is trying to insert a third and fourth source into programs that were designed around incumbents, and it is doing so with private capital rather than through the traditional cost-plus contracting route.

Artillery remains central to that argument. Edwards told Tectonic Defense that Europe fired 16 million rounds in about 18 months, and that drones notwithstanding, artillery is still needed on the battlefield. Base-bleed motors are one of the cheapest ways to add range to shells already in inventory, which makes them attractive to allied governments buying for volume rather than for prestige. Annual U.S. Army procurement of Hydra-70 rockets has run in excess of 330,000 units, a figure that shows how much of this market is driven by consumable, repeat orders rather than by a handful of large programs.

There are limits worth naming. Firehawk has not disclosed how many Hydra-70 rockets or rocket motors it has delivered to the U.S. military, nor when the Oklahoma plant will reach full-rate production. Its Army qualification path still runs 12 to 18 months, which means the near-term revenue case rests on allied sales through General Dynamics rather than on American orders, and a qualified second source is only useful to the Pentagon once qualification actually closes.

Next Up

Execution now becomes the story. The Great Plains Arsenal must commission on schedule in early 2027, climb to low-rate production by mid-2027, and then scale toward tens of thousands of motors a month by late next year. The Crawford site must convert its 40,000-rocket capacity into steady output while the company works toward 10,000 rockets a month and an eventual 120,000 a year.

Edwards has said Firehawk will do over nine figures in revenue next year, and that in ten years it will be one of the core pillars of the defense industrial base. Those are the numbers and the timeline against which the $1.4 billion valuation will be judged, and they are now the company's problem to prove rather than its investors'.
