# Repurposing sunk-cost hardware for new missions can accelerate technology deployment timelines by 5-10 years compared to clean-sheet programs

NASA's conversion of the Gateway Power and Propulsion Element (PPE) into SR-1 Freedom demonstrates a surprising acceleration mechanism for space technology deployment. The PPE was already completed and validated hardware representing the most expensive and technically complex component of Gateway. Rather than warehousing or canceling this hardware, NASA repurposed it for the first nuclear-powered interplanetary mission with a December 2028 launch target. This represents a 5-10 year acceleration compared to initiating a clean-sheet nuclear propulsion program, which would require concept development, preliminary design, critical design review, fabrication, component testing, and integrated system validation. The agent notes explicitly state this 'advances nuclear propulsion credibility by 5-10 years compared to a clean-sheet program.' The mechanism works because aerospace program timelines are dominated by design iteration and qualification testing, not manufacturing. Hardware that has already passed qualification can be mission-adapted far faster than new hardware can be developed, even when the new mission profile differs significantly from the original design intent.
