Powering Mithril Defense's Mission Through Supply Chain Resilience

Mithril Defense partners with Sustainment to source faster, surface US-based supplier alternatives, and build an auditable, NDAA-compliant supply chain at mission speed.

Mithril Defense recently partnered with Sustainment to design and operate a US-centric, NDAA-compliant supply chain that accelerates time-to-market while reducing unit cost. By leaning on Sustainment's platformand Customer Success team, Mithril rapidly identifies best-fit US supplier alternatives, increases RFQ velocity, and expands sourcing coverage across its entire supply chain.

About Mithril Defense

Mithril Defense is what the new American defense industrial base looks like. Founded in 2023 in Austin, Texas by technology entrepreneur Justin Marston and Bill King, a retired Navy SEAL command master chief, the company designs, develops, and manufactures small FPV drone systems for close-quarters and exterior missions, flown by a team drawn from former JSOC and SWAT operators and professional FPV pilots.

What sets Mithril apart is how seriously it takes the supply chain as a weapon system. The company designs and manufactures its core electronics in the United States, including Arkenstone, its NDAA-compliant flight computer, and builds through a vetted network of domestic manufacturing partners. That discipline is earning notice: Mithril was selected as a Phase II qualifier in the Drone Dominance Program alongside the Defense Innovation Unit, and its Campus Guardian Angel rapid-response service, recently covered by CBS News, feeds real-world operational experience directly back into its defense systems.

The challenge: compliance can't slow the mission

For an emerging defense company, NDAA compliance isn't paperwork, it's award eligibility. Every component sourced from a restricted origin is a risk to fielding, and every requirement shift can send a team back into weeks of supplier searching. Doing that with a lean operations team, at production scale, on program timelines, is where most build plans stall.

The solution: a supply chain designed, not inherited

Working with the Sustainment platform and Customer Success team, Mithril is establishing a scalable, secure, and auditable supply chain architecture that meets the demands of defense-grade production while improving cost transparency, supplier optionality, and manufacturing resilience. When requirements shift, the team surfaces qualified US-based alternatives in days rather than weeks, keeps bid velocity high, and maintains the audit trail that compliance reviews demand, without slowing the build.

"Sustainment has become a true force multiplier for Mithril. Their platform and team allow us to source faster, find US-based alternatives we didn't know existed, and keep our build plan moving even when requirements shift. This partnership is accelerating our path to fielding a fully NDAA-compliant system."

The results

Faster supplier identification. Best-fit US-based supplier alternatives surfaced rapidly, including options the team didn't know existed.

Higher bid velocity. More bids, from more qualified suppliers, with sourcing coverage expanded across the entire supply chain.

NDAA-compliant architecture. A stronger, auditable, defense-grade supply chain that supports compliant fielding.

Resilience is the mission

Mithril's story is the reindustrialization thesis in miniature: a defense company that treats its supply chain as core to the weapon system, built on American suppliers, with compliance designed in rather than bolted on. Sustainment's role is to make that architecture fast, so that doing it right never means doing it slow.
