Pentagon Ramps Up Hypersonic Weapons Production as Startups Cut Costs

The Pentagon is ramping up hypersonic weapons production as startups find ways to cut costs. A single Army Dark Eagle hypersonic missile could cost more than $40 million, while a Tomahawk costs about $2.6 million. That gap has pushed the Pentagon to look beyond its usual suppliers for cheaper and faster production. Traditional defense contractors have faced production pressures linked to shortages of critical components. Therefore, these newer companies are exploring alternative suppliers and manufacturing techniques to increase output. The goal is to deliver weapons faster without sacrificing performance, safety or quality. The Pentagon is betting that lower prices and higher volume can finally go hand in hand.

The push comes as Washington seeks to strengthen its weapons supply chains amid rising demand for missiles and rocket motors. The Pentagon is seeking faster weapons production as U.S. defense startups have challenged the traditional manufacturing methods. A new wave of defense startups is answering the call, using parts and methods borrowed from other industries like automotive electronics, oil and gas equipment, pharmaceutical technology and 3D printing. These approaches could help reduce costs and ease supply bottlenecks affecting missile production. However, startups must still prove they can manufacture reliable weapons at the scale the U.S. military requires.

Startups Tap Automotive Chips and Industrial Technology to Cut Missile Costs

Castelion, a California-based defense startup by former SpaceX engineers, is applying commercial technology to hypersonic missile manufacturing cutting production costs by using automotive processors, precision-machined oil and gas components. Its Blackbeard missile uses programmable chips built for driver-assistance systems and electric vehicles. CEO Bryon Hargis puts the missile’s price under $500,000, which he calls “incredibly cheap”. These parts can cost up to 90% less and arrive six times faster than comparable aerospace components. In May 2026, Castelion announced a Pentagon agreement targeting production of at least 500 Blackbeard hypersonic missiles annually, subject to testing and validation. The Navy ordered 50 early weapons for $23.4 million in June. A $90 million award came in August, and a September order worth up to $200 million followed.

Meanwhile, Anduril Industries is using pharmaceutical mixing technology to accelerate solid rocket motor production, they use drugmaking mixers to cut the propellant mixing time from hours to minutes. The company says the equipment increases production more than tenfold compared with its previous mixing systems. This approach could help address bottlenecks in manufacturing solid rocket motors. Other companies are using 3D printing to shorten production timelines. New Mexico-based X-Bow Systems specializes in solid rocket motors made through additive manufacturing techniques. Texas-based Firehawk Aerospace also uses 3D printing to manufacture rocket motors. These innovations aim to reduce costs and increase U.S. hypersonic weapons production. However, these technologies must still meet all the military standards for consistency, reliability and performance.

Hypersonic Weapons Offer Speed but Present Major Production Challenges

Hypersonic weapons travel at Mach 5 or faster, equivalent to at least five times the speed of sound (767 mph). Two major categories are hypersonic glide vehicles and hypersonic cruise missiles. Glide vehicles ride a rocket booster before gliding toward the target. Cruise missiles use air-breathing scramjet engines to hold their speed. Unlike ballistic missiles, both can steer in flight and stay lower in the atmosphere. Radar therefore spots them late, leaving defenders little time to respond. The Army’s Dark Eagle is designed to reach more than 1,725 miles. A strike could land in 15 to 30 minutes. The numbers show why the military wants them.

However, speed brings hard engineering problems. Extreme heat, propulsion and flight control demand long test campaigns. The Pentagon spent about $1.09 billion testing boost-glide systems from fiscal 2021 to 2025. Solid rocket motors also need slow curing and X-ray inspection. A Congressional Budget Office review found hypersonic missiles could cost about one-third more than comparable ballistic missiles. The U.S. military has also never used one in combat. Ultimately, the Pentagon’s push shows that hypersonic power now depends as much on affordable manufacturing as on speed. If startups hit their price and volume targets, the U.S. could field these weapons in far larger numbers.
