The problem first crystallized for Cooper McBride somewhere between shipping his six-thousandth battery pack to low Earth orbit and watching defense contractors accept year-long waits for similar hardware. At SpaceX, where he'd helped power thousands of Starlink satellites, three weeks meant iterating through a design cycle. In the broader aerospace industry, three weeks barely covered the initial paperwork.
McBride and his SpaceX colleague Lucas Maddox decided that gap wasn't about physics or safety—it was inertia wearing the costume of careful engineering.
Their answer is Kyten Technologies, a Seattle startup that just emerged from Y Combinator with an audacious promise: custom aerospace battery packs, fully qualified, in 21 days. One week to design. One to validate through automated testing. One more to reach production volumes in the thousands of units annually. It's the kind of timeline that makes legacy suppliers wince, and which the founders insist the U.S. defense industrial base desperately needs as it races to field tens of thousands of drones, submarines, and satellites.
Whether aerospace's regulatory thicket will allow such speed remains an open question. But Kyten is betting that software-defined manufacturing and brute-force automation can finally drag battery supply chains into something resembling the startup century.
When Starlink Speed Meets Defense Timelines
The pitch hinges on a central conviction: most aerospace battery delays aren't technically necessary. They're structural.
Traditional Tier 1 suppliers stretch design and qualification across six to twelve months, then tack on another half-year or more to ramp production. Kyten's founders argue that model made sense when programs moved slowly and volumes stayed modest. Now, with the Pentagon pushing "attritable" autonomous systems by the thousands and congressional restrictions kicking Chinese battery makers out of U.S. supply chains, the old pace looks less like prudence and more like paralysis.
Kyten's answer involves adaptive battery pack architecture—think modular building blocks that accommodate custom geometries without starting from scratch each time. The company says it can handle any cell chemistry, any form factor. Wire-bonded or welded interconnects. Integrated battery management systems tailored to customer protocols. Thermal controls. All of it routed through what Kyten describes as an in-house automated qualification setup designed to compress months of certification into days.
That's the theory, anyway. The startup hasn't yet named customers, disclosed which specific certifications it targets (UN 38.3 for transport? DO-160 for avionics? MIL-STD-810? Naval or space standards?), or detailed its factory footprint. According to its late-January 2026 Y Combinator launch, Kyten is actively hunting early adopters. Production capacity exists, the founders say. Proving it under real-world aerospace certification regimes comes next.
The SpaceX Playbook, Applied
McBride's resume reads like a tour through high-rate hardware. Electrical engineering degree, focus on power electronics. Stints at Tesla, then SpaceX, where he led hardware testing at Starlink and later built the test organization at Shield AI. Maddox followed a parallel track: urgent test and manufacturing challenges at Starlink, co-founder of the University of Washington's solar car team, electrical engineering with a power systems bent.
Together, they claim responsibility for more than 6,000 battery packs now circling Earth in low orbit. Six years at Starlink embedded a particular worldview—that rapid iteration and high-volume production aren't luxuries reserved for consumer electronics. They're necessities, even in aerospace, if you're willing to rethink the process.
The pair frames existing battery supply chains as an "existential risk" to U.S. programs, language that carries more than a little Silicon Valley swagger. But it also taps into genuine anxiety rippling through the defense sector.
Kyten raised a $500,000 convertible note in mid-February 2026, per CB Insights, days before its public launch. The team remains just the two founders. Small, focused, and convinced they've seen the future at SpaceX.
A Market Under Pressure
The timing is deliberate. Multiple forces are squeezing aerospace battery supply chains simultaneously, creating an opening Kyten hopes to exploit.
The Pentagon's Replicator initiative, announced in 2024, aims to deploy "multiple thousands" of autonomous systems by August 2025. That's a lot of batteries, and fast. The FY2024 National Defense Authorization Act, meanwhile, began phasing out DoD procurement from Chinese manufacturers—CATL, BYD, and others—with compliance deadlines rolling into 2027. A December 2025 FCC ban on new sales of foreign-made drones from companies like DJI has further accelerated the push toward domestic suppliers.
Kyten's pitch invokes all of it, claiming American manufacturers are scrambling to build more than 100,000 autonomous air, sea, and space vehicles. The number appears in the company's own materials without external sourcing, so it's unclear whether that reflects firm Pentagon orders or aspirational industry math. But the directional pressure is real.
Recent contract activity tells the story in dollars: Amprius landed a repeat $3.5 million UAV battery order in 2025. Lyten dedicated lithium-sulfur capacity to defense and satellite customers. EaglePicher and Ultralife continue pulling down multimillion-dollar DoD and Defense Logistics Agency awards.
There's demand. The question is whether Kyten can meet it on its own compressed schedule.
The Volume Versus Customization Problem
Kyten isn't entering a vacuum. EaglePicher has been a defense battery mainstay for decades, recently expanding facilities and holding ongoing USAF contracts. Ultralife won 2025 DLA awards and showcased subsea packs at DSEI. Packet Digital builds custom UAS batteries, including packs for Anduril's Ghost VTOL. CRG Defense markets U.S.-made cells positioned as supply chain alternatives to foreign manufacturers. MaxAmps assembles LiPo and Li-ion packs domestically for UAV customers it says include Lockheed Martin and NASA.
Then there are the advanced chemistry entrants: Amprius ships high-energy silicon anode cells for UAVs. Lyten opened orders for lithium-sulfur batteries aimed at drones and satellites under an explicit national security banner.
What Kyten offers—what it has to offer to justify its existence—is speed at custom scale. That's a harder trick than it sounds.
LinkedIn commentary on the Y Combinator launch surfaced a tension worth noting: Starlink's production prowess came from iterating a single product at extraordinary volume. Kyten is promising to apply that manufacturing discipline to bespoke, one-off designs across wildly different platforms. Drones aren't satellites aren't submarines. Qualification for each varies. So do thermal profiles, vibration specs, and safety regimes.
Can automated testing really compress that complexity into a week? Or will real-world certification requirements force Kyten to quietly stretch timelines until "three weeks" becomes shorthand for "faster than the other guys, but not actually three weeks"?
What Hasn't Been Said
Kyten's launch materials emphasize turnkey design, in-house qualification labs, and capacity for thousands of units per year per product. The company supports "fully custom geometry," integrated battery management, resettable fusing, thermal controls, and engineered transport cases.
What it hasn't disclosed: facility square footage. Production line specs. Named customers. The full scope of its qualification capabilities.
For now, the founders are taking meetings. Email: [email protected]. Pilots will presumably follow, and those early contracts will reveal whether three weeks was a realistic goal or startup bravado meeting aerospace reality.
The defense industrial base has absorbed countless promises of disruption over the past decade. Some delivered. Many didn't. Kyten's founders are betting that a factory optimized for speed—and staffed by engineers who've already proven they can ship thousands of packs to orbit—can carve out a niche in a market that suddenly has political urgency and procurement dollars behind it.
Their thesis is simple, maybe too simple: aerospace battery supply chains are slow not because they have to be, but because no one's forced them to move faster. Whether qualification timelines bend to that logic, or whether Kyten ends up learning hard lessons about why aerospace moves the way it does, will determine if this bet reshapes the market or becomes a footnote about underestimating bureaucracy.
Either way, the industry is watching. And the clock, as Kyten would tell you, is already running.
