Key Points Manufacturing Readiness Levels (MRLs) are a DoD-developed framework that measures how ready a technology or system is to move from concept into full-rate production — on a scale of 1 to 10. MRLs 1–3 establish the manufacturing concept. MRLs 4–6 build and validate the process. MRLs 7–10 prove and sustain production at scale. MRL and TRL are related but distinct: a technology can be proven while the manufacturing process to build it reliably at scale remains immature. Misalignment between the two is one of the most common sources of program delay. Each MRL maps to a DoD acquisition milestone: Milestone A, B, and C each carry target MRL thresholds that programs must meet to advance. Modus Advanced supports programs across the MRL spectrum , from early prototyping through full-rate production, with the engineering depth and vertical integration to prove it. Why Manufacturing Readiness Levels Exist A system can work perfectly in a lab and still fail in production. That's the problem Manufacturing Readiness Levels were designed to solve.
