Pentagon accelerates defense modernization through startup partnerships and long-term contracts

We do not build enough, we do not go test enough
Castelion's CEO on what the Pentagon is finally correcting after decades of caution.

So the Pentagon is essentially saying it needs both the old guard and the new guard. Why not just pick one approach?

Mimi

Because they're solving different problems. Raytheon and Lockheed Martin can produce Tomahawks and Patriots in volume—proven systems that work in actual combat. But that takes time to scale up. Startups like Rocket Lab and Castelion can experiment and iterate faster, which matters for emerging capabilities like hypersonic weapons.

But here's what I want to know: has Castelion actually delivered a working Blackbeard hypersonic weapon yet, or is the Pentagon just funding the promise? The reporting says they have a "multi-year agreement to eventually field" it—that's conditional language.

Mimi

Right, it's conditional. They've met some performance targets, but the full production commitment depends on hitting future milestones. That's the startup model—you fund the risk.

Mark

And Rocket Lab has already received $2 billion. That's not exactly a scrappy startup anymore.

Mimi

No, but they're still moving faster than a traditional contractor would. They've done multiple launches of the Haste Launch Vehicle. The Pentagon sees that speed as valuable.

Luke

The question is whether speed without proven reliability is actually valuable in weapons systems. The reporting doesn't tell us whether these startup systems have been tested in combat or whether they've failed any critical tests.

Mark

So we're essentially watching an experiment unfold.

Mimi

Yes. The Pentagon has decided it needs to experiment. The Defense Innovation Unit's budget growing to nearly $1 billion annually shows this isn't a one-off—it's a structural shift.

Luke

And if the startups fail to deliver? The Pentagon still has those multi-year contracts with the primes locked in, so there's a safety net.

Mimi

Exactly. It's hedged. They're not abandoning proven systems; they're adding new bets on top of them.

  • The Pentagon is moving with unusual speed, locking in tens of billions in multi-year contracts — including $22.9B for Tomahawk missiles and $58.62B for Patriot systems — signaling a department that believes the window for preparation is narrowing.
  • Tripling Patriot missile production in a single year is not a routine procurement adjustment; it is an institutional alarm bell dressed in contract language.
  • The Defense Innovation Unit, now funded at nearly $1 billion annually, is the Pentagon's deliberate bet that commercial agility can be grafted onto military necessity — a structural disruption to how America has built weapons for decades.
  • Startups like Rocket Lab and Castelion are not waiting in line — they are already launching hypersonic test vehicles and securing half-billion-dollar contracts, moving at a tempo that legacy contractors were never designed to match.
  • Lessons absorbed from Ukraine's battlefield have hardened into policy: unconventional companies with out-of-the-box thinking are no longer a curiosity but a strategic requirement, according to lawmakers shaping the defense agenda.

In a season of strategic urgency, the American War Department has chosen not to choose between the old and the new — instead binding itself to both. Billion-dollar commitments to proven defense giants run alongside deliberate investments in startups whose greatest asset is the freedom to fail fast and learn faster. The Pentagon's dual wager reflects a civilization grappling with the pace of modern conflict: that neither tradition alone nor innovation alone is sufficient, and that the future of national security may depend on holding both in tension.

The Pentagon has arrived at an unusual conclusion: it needs to move in two directions at once. Over the past year, the War Department has committed enormous sums to the defense giants who have long anchored American military production, while simultaneously routing serious money and attention toward startups that promise to think and build differently.

The scale of the traditional contracts is striking. Raytheon secured $22.9 billion to produce Tomahawk missiles across seven years. Lockheed Martin received $58.62 billion for Patriot Missile Segment Enhancements — a system the Pentagon credits with proven combat performance. Northrop Grumman and Lockheed Martin together landed a $1 billion framework for THAAD components. Undersecretary Michael Duffey called these arrangements unprecedented, and the commitment to triple Patriot production year-over-year underscores just how urgently the department views the need for more weapons, delivered faster.

But the established contractors represent only half the strategy. The Defense Innovation Unit — tasked with pulling commercial technology and startup ingenuity into military applications — has grown to nearly $1 billion in annual funding, a signal that this is a sustained institutional shift rather than an experiment. The underlying logic is that large contractors excel at volume and complexity, while startups excel at speed, experimentation, and asking questions that entrenched hierarchies tend to suppress.

Rocket Lab, with over $2 billion in government awards, is now testing its Haste Launch Vehicle to accelerate hypersonic weapons development alongside the Defense Innovation Unit. Castelion, a newer entrant, is pursuing manufacturing speed through rapid prototyping — building, testing, finding problems, and correcting them in quick succession rather than perfecting designs on paper for years. The Pentagon has agreed to eventually field Castelion's Blackbeard Hypersonic Weapon if performance targets are met; the company has already secured $500 million in military contracts in eighteen months and announced $1 billion in new funding.

Representative Michael McCaul, pointing to Ukraine as a proving ground for unconventional approaches, argued that startups bring exactly the creativity and speed the defense industrial base now requires. The large contractors will continue building the major platforms, he suggested, but those systems move slowly — and the threats are not waiting.

What the Pentagon has effectively decided is that the risk of not integrating startup agility into its industrial base now outweighs the risk of trying. Whether companies like Rocket Lab and Castelion can deliver advanced systems at the reliability and scale the military demands remains an open question — but the department has clearly concluded it cannot afford to leave that question unanswered.

The Pentagon is betting that speed and fresh thinking can reshape how America builds weapons. Over the past year, the War Department has committed to an unusual dual strategy: locking in massive, multi-year contracts with the defense giants who have proven they can deliver established systems at scale, while simultaneously opening doors to startups and smaller firms that promise to move faster and think differently about what's possible.

The numbers tell the story of a department in a hurry. A $22.9 billion agreement with Raytheon secures Tomahawk missile production through a seven-year window. Lockheed Martin landed a $58.62 billion contract for Patriot Missile Segment Enhancements—a system the Pentagon credits with unmatched performance in actual combat. Northrop Grumman and Lockheed Martin together received a $1 billion framework for THAAD components. These are not typical procurement arrangements. Michael Duffey, the Undersecretary of War for Acquisitions and Sustainment, called them "unprecedented deals." For Patriot systems alone, the Pentagon has committed to tripling production compared to the previous year, a dramatic acceleration that signals how seriously the department views the need for more weapons, faster.

But the long-term contracts with established contractors tell only half the story. The War Department has also been channeling resources into the Defense Innovation Unit, a division tasked with bringing commercial technology and startup ideas into military applications. The unit's budget has grown to nearly $1 billion annually in recent years—a substantial commitment that reflects a deliberate shift in how the Pentagon thinks about staying ahead. The logic is straightforward: the large defense contractors excel at building complex, proven systems in volume. Startups excel at moving quickly, experimenting without fear, and asking questions that established hierarchies might never ask.

Rocket Lab, founded in 2006, exemplifies this new relationship. The company has received more than $2 billion in government contract awards and is now working with the Defense Innovation Unit to test its Haste Launch Vehicle, designed to accelerate hypersonic weapons development. Brian Rogers, the company's Vice President of Global Launch Services, described the partnership as a climb up the ladder: "We've moved up the food chain, and now we are amongst the preeminent missile and missile defense test programs in the United States." The company has already conducted multiple launches and has more planned, testing various technological applications.

Castelion, a defense technology startup, is pursuing a different angle: manufacturing speed. The company's co-founder and CEO, Bryon Hargis, argues that the defense industry has abandoned practices that worked during the Apollo program—the willingness to build something, test it, find the problems, and fix them in rapid succession rather than spending years perfecting designs on paper. "We believe that it's much faster if you just go out and build the object you're trying to build into inner manufacturing, and then you find all of the problems in that process, and you correct them," Hargis said. The Pentagon has responded with a multi-year agreement to eventually field Castelion's Blackbeard Hypersonic Weapon, contingent on the company meeting performance targets. Castelion has already secured $500 million in military contracts over the past 18 months and announced $1 billion in new funding.

Representative Michael McCaul of Texas, speaking to the broader strategic shift, framed startups as essential to the Pentagon's future. He pointed to lessons from Ukraine, where smaller companies and unconventional approaches proved their value in real conflict. "The startups have this ability of innovation to move at a faster speed and a more innovative technology, more creativity in the process, out-of-the-box thinking that we desperately need for our defense industrial base," McCaul said. The large contractors will continue to build the aircraft carriers and major platforms, he suggested, but those systems move slowly. Startups move differently.

What emerges from these contracts and partnerships is a Pentagon that has concluded it needs both stability and speed—the proven capacity of Raytheon, Lockheed Martin, and Northrop Grumman to deliver weapons systems that work, paired with the agility and experimental mindset of companies like Rocket Lab and Castelion. The Defense Innovation Unit's expanding budget suggests this is not a temporary experiment but a sustained commitment to reshaping the defense industrial base. Whether startups can deliver on hypersonic weapons and other advanced systems at the scale and reliability the Pentagon demands remains to be seen, but the department has clearly decided the risk of not trying is greater than the risk of trying.

These are unprecedented deals. Nobody's been able to deliver the quality and the performance that Tomahawk and the Patriot provide for our war fight.
