# Lunar ISRU at TRL 3-4 creates a 7-12 year gap before operational propellant production making the surface-first architecture vulnerable to development delays with no backup propellant mechanism
Current lunar ISRU water extraction technology sits at TRL 3-4 with demonstrated flow rates of 0.1 kg/hr water vapor. To support meaningful propellant production for refueling lunar vehicles (tens of tons per year), ISRU must scale by 3-4 orders of magnitude from current demo rates. The standard TRL progression from TRL 3-4 to TRL 9 (operational production) typically requires 7-12 years for deep tech with no direct terrestrial analog. This timeline is consistent with Project Ignition's Phase 2 (2029-2032) targeting operational ISRU beginning, but notably no specific kg/hr production targets are published. The architectural risk is amplified by the cancellation of the three-tier Gateway architecture: the previous design included an orbital propellant depot as a bridge mechanism, but the current surface-first path has no fallback propellant source if ISRU development slips. Phase 1 MoonFall hoppers (2027-2030) are designed for prospecting, not extraction. Phase 2 human presence relies on Earth-sourced supplies plus early ISRU experiments. Full operational ISRU capability may not arrive until Phase 3 or later, meaning the surface-first architecture operates without self-sufficiency for 10-15 years while depending entirely on Earth supply chains.
