In a major strategic shift, the Pentagon is asking prime defense contractors to invest their own capital—billions of dollars—to expand munition production "on spec." This pushes immense financial risk onto publicly traded companies, a difficult ask given the government's historically cyclical and unreliable purchasing patterns.

Identifying the defense industrial base as "rotted out," Mock Industries is taking a bottom-up approach. Instead of just building platforms, it vertically integrates to produce high-performance subsystems (radars, engines) and sells them to other primes, aiming to fix the entire ecosystem.

The push to build defense systems in America reveals that critical sub-components, like rocket motors or high-powered amplifiers, are no longer manufactured domestically at scale. This forces new defense companies to vertically integrate and build their own factories, essentially rebuilding parts of the industrial base themselves.

The high cost of defending against advanced AI cyber threats could bankrupt small and medium-sized businesses in the defense industrial base. Their inability to afford next-generation security, like dedicated hardwired networks, threatens to cripple the military's supply chain for critical components.

While the US can assemble advanced drones, a significant national security risk lies in the supply chain for their basic components, many of which come from China. The strategic imperative is to "shift left" and onshore the manufacturing of these foundational parts to secure the entire defense industrial base, not just the final product.

The current conception of the defense industrial base focuses on large primes like L3 and General Atomics. However, 98% of US manufacturing is done by small businesses that are not integrated into the defense supply chain. A key investment would be creating a pathway to bring these smaller, agile companies into the fold.

Post-WWII, 94% of major weapons spending went to dual-purpose companies like Chrysler (missiles) and Ford (satellites). The modern defense industrial base, comprised of pure-play specialists, is a recent development that has reduced manufacturing scale, flexibility, and innovation.

Supply chain vulnerability isn't just about individual parts. The real test is whether a complex defense system, like a directed energy weapon, can be manufactured *entirely* from components sourced within the U.S. or from unshakeable allies. Currently, this is not possible, representing a critical security gap.

Over-reliance on bespoke, defense-only suppliers creates a fragile industrial base. The Department of Defense now champions a "commercial first" strategy, prioritizing designs with commercial applicability to build resilience, reduce costs, and avoid self-inflicted vulnerabilities from single-source dependencies.
