**A missile startup that can't get circuit boards on time isn't really a missile startup.**

For a decade the hot defense startups built drones, satellites and autonomous boats. The new argument from a16z's American Dynamism team is that **the bottleneck has moved down a layer:** to the machine shops, circuit-board suppliers, copper mines and power plants those systems depend on. As one of them puts it:

> You don't have a defense industrial base without an industrial base

On the a16z show, partners Erin Price-Wright and Connor Love talk through the firm's 2026 American Dynamism 50 list. Its theme is its title: **production is deterrence.**

*In short: a country's ability to deter a war now depends on how fast it can make things, from raw materials to finished weapons. Founders are rebuilding that whole chain, and the payoff, the hosts argue, reaches well beyond defense.*

## 1\. Three pillars, one chain

- **Systems** are what gets fielded: Anduril's aircraft, Castelion's hypersonic missile, Saronic's autonomous boats.
- **Factories** build them at volume: Hadrian's automated machining, Senra's wire harnesses, Diode's circuit-board tools.
- **Inputs** keep the line moving: Mariana Minerals' Utah copper mine, General Matter's uranium enrichment, Base Power's home batteries.

Drawing it as one chain makes the point: **a weakness anywhere stops everything above it.**

But why should anyone outside defense care?

## 2\. Defense as the first customer

**The same factory and the same minerals feed cars, robots and toys.** The hosts' example is DJI. As they tell it, the Chinese company started with consumer drones, built a large production business, and the people behind it now lead in robots,

> because what is very similar to a drone motor is a robot actuator, which is the hardest part of building a robot.

Process knowledge moves between military and civilian work, and that "has always been how it works."

That makes defense a useful first buyer. A new US circuit-board fab needs expensive machines. If a defense customer pays for the first run, it helps cover the capex, and the line can then sell cheaper boards to everyone else. **In our reading, this is the episode's central economic idea:** government demand underwrites the first, most expensive version of a factory, and the commercial market benefits after that.

## 3\. Rebuilding every node

When no supplier base exists, **companies build it themselves,** as SpaceX and Tesla did. Mariana Minerals bought a copper mine to own the whole process from ore to refined metal. Own the chain, the hosts say, and "you can look at every single node from a first principles perspective," asking whether a hundred-year-old process is still right.

Hadrian, which runs automated precision-parts factories, shows there's **no silver bullet.** "It's actually 15 or 20 different things": quoting the part, taking the order, machining it, inspecting it, moving it.

**AI helps, within limits.** "AI cannot turn a wrench yet," one host says. Where it does help is the shift from low-mix, high-volume lines, which pay only when you make a lot of one thing, to **high-mix, low-volume work.** With the right software, technicians without college degrees can change what a line makes far more cheaply. Designing for manufacturing from day one does the rest.

And the supplier layer is starting to deliver:

- **Circuit boards:** one portfolio company used to order twice the boards it needed because half failed quality tests. With new suppliers it sees pass rates of "70, 80, 90%."
- **The grid:** a move from mechanical equipment installed in the 1970s and 1980s to power electronics and battery storage. Once that step change starts, "you're never going back," even if demand forecasts prove too high.

![Bar chart of circuit-board pass rates rising from about 50% to 70 to 90%, beside a loop: defense buys first, pays down capex, line scales, cheaper parts for all](https://storage.ghost.io/c/d7/93/d793216c-cf13-441f-bdae-4f3aef998c0e/content/images/2026/10/fig2-30.png)

## 4\. Founders, focus and money

**Many new founders are second-generation:** alumni of SpaceX, Anduril and Palantir who saw the gaps from inside. They sell to one another, like Y Combinator companies being each other's first customers: "that's how ecosystems get built."

**Focus matters.** Castelion, they say, spent two and a half to three years on its first hypersonic missile while others urged it to go multi-product. Doing one hard thing well builds the supply chain, process knowledge and customer trust that make the second and third easier.

**The money has followed.** More risk capital went into defense in the first half of 2026 than in all of 2025, they say, and the old "valley of death" between prototype and production contract is "starting to disappear." They see private markets following success, not a top-down plan.

Two warnings close the episode:

- **Physical things take years,** and the work is rough.
- **Bring communities along.** Amca, they note, partners with small machine shops instead of firing their managers.

On the chart of US versus Chinese power production, one host says closing the gap is "not a technology problem." It's a question of national will.

## Weighing it: what holds up

**Confirmed:**

- **The list:** the 2026 American Dynamism 50, titled "Production is Deterrence," was published on October 29, 2026, with the three pillars described; Amca, Hadrian, Castelion and Mariana Minerals are on it.
- **Mariana** bought a Utah copper mine and refinery, the former Lisbon Valley operation, in late 2025, and restarted it as Copper One in 2026.
- **Funding:** defense-tech startups raised about $12.3 billion in the first half of 2026, per the Financial Times and The Logic, above roughly $10 billion for all of 2025.
- **DJI** has moved into robotics: its ROMO robot vacuum reuses drone sensing technology.

**Overstated:** JPMorgan's "trillions." Its Security and Resiliency Initiative is a $1.5 trillion, ten-year plan to finance and facilitate, with $10 billion of the bank's own direct investment.

**Not checked:** the circuit-board pass rates (from one unnamed portfolio company), the Castelion timeline, and the claim that DJI built a large defense business and that its people now lead world robot production. Treat that as the hosts' reading.

**Interests:** a16z invests in many of the companies discussed, so this is partly a portfolio showcase.

## Long Talk Short

- a16z's 2026 American Dynamism 50 argues deterrence now depends on production capacity, not just better weapons.
- One chain: Systems, Factories, Inputs. A weak link anywhere stalls the systems on top.
- Defense can be the first buyer, paying down capex for factories that then serve cars, robots and consumer goods.
- Where suppliers don't exist, founders integrate vertically and rethink each step. There's no single silver bullet.
- Software makes high-mix, low-volume lines economic. "AI cannot turn a wrench yet."
- Defense startups raised more in the first half of 2026 than in all of 2025.

**The one thing to remember:** to judge any hardware company, look past the product to the boards, metals and power behind it. That's where the real bottleneck usually is.
