Hadrian Raises $1.37B as 3D Printing Fuels Defense Manufacturing Scale

The Raise

Hadrian closed a $1.37 billion Series D equity round at a post-money valuation of $7.87 billion. The round was anchored by JPMorgan Chase's Strategic Investment Group and co-led by WCM Investment Management, Washington Harbour Partners, Valor Equity Partners, 137 Ventures, and Baillie Gifford. Other participants included Founders Fund, Andreessen Horowitz, CapitalG, Lux Capital, Altimeter, Apollo funds, T. Rowe Price funds, and 1789 Capital. That is a long list of serious names backing a manufacturing company.

The valuation is roughly five times where Hadrian stood after its $260 million Series C, which closed in mid-2025. Total lifetime funding is now close to $2 billion, according to PitchBook estimates. The pace of the increase reflects more than company performance alone. It reflects a broader shift in how the US defense establishment thinks about production capacity.

What Hadrian Actually Builds

Hadrian describes itself as a defense manufacturer, but the more precise description is a factory-builder for defense manufacturers. Its proprietary Opus software stack interprets legacy engineering designs, automates machining and inspection workflows, and coordinates robotic production cells. The stated goal is to reduce the time between a defense program receiving funding and parts reaching the field.

The company currently operates four factories. Factory 2 in Torrance, California handles precision components. Factory X, also in Torrance, is its R&D facility. Factory 3 in Mesa, Arizona is a 290,000-square-foot site focused on missile, jet, rocket, and munitions components. The Muscle Shoals, Alabama facility concentrates on submarine parts. Combined, the footprint approaches three million square feet.

Where 3D Printing Fits In

Additive manufacturing is embedded in Hadrian's production stack, though the company does not market itself primarily as a 3D printing story. Its factories combine CNC machining, robotics, and metal 3D printing to produce complex geometry that would be expensive or impossible to make through conventional tooling. The ability to go from a digital design file to a finished part without creating hard tooling is particularly valuable in low-volume, high-mix defense programs where demand forecasts shift as programs evolve.

The Series D funds are earmarked for new factory construction, expanded R&D, and additional production lines focused on munitions and autonomous systems. CEO Chris Power has said the company wants to move beyond precision parts to delivering complete mission-critical systems. That positioning puts Hadrian in direct competition with the traditional defense industrial base, which has struggled for years with long lead times, quality escapes, and workforce shortages.

The Bigger Picture

Hadrian's fundraising success is part of a broader wave of defense tech investment. The Trump administration has proposed a $1.5 trillion defense budget, and both the Pentagon and Congress have signaled that domestic production capacity is a national security priority. The US military's experience with supply chain disruptions during recent high-demand periods has accelerated interest in domestic, software-driven manufacturing.

The question is whether factory automation can actually close the gap between US defense spending and US defense production speed. Hadrian's valuation implies that investors believe it can. The next twelve months will show whether factory output matches the ambition behind the funding round.
