CI-Nuclear Propulsion Engine (CI-NPE)
Compact fusion-fission reactor: Mars in 3 months, meltdown-proof, submarine-quiet.
Executive Summary
Nuclear Propulsion Engine (NPE) is the next-generation nuclear thermal propulsion for aerospace and naval applications—replacing chemical rockets and steam-loop nuclear systems with a compact fusion-fission reactor delivering continuous thrust, 8x energy density improvement, and radical size reduction. Purpose-built for the Eagle-S ELV, Space Eagle space-plane, advanced maritime (H-SES) and submarine propulsion.
The Problem
Chemical propulsion has reached its performance ceiling—limiting deep-space missions to 6+ months to Mars and constraining payload fractions. Current nuclear concepts rely on steam-loop architectures generating detectable acoustic signatures in naval use and severe weight penalties in aerospace. The U.S. Navy’s 101 reactor-powered vessels face a shrinking vendor base and aging technology with no next-generation replacement program.
The Solution
CI’s compact modular reactor eliminates the steam loop entirely, directly coupling nuclear energy to electrical propulsion at one neutron per 17.6 MeV—8x more energetically favorable than conventional designs. Continuous thrust vectoring replaces pulsed cycles, reducing airframe stress. Driver circuits mount outside the reactor footprint, enabling modular integration in submarines, missiles, and spacecraft. Mars transit drops from 6+ months to approximately 3 months.
Market Opportunity
The global space propulsion market reached $13.4B in 2025, projected to exceed $20B by 2030 at 11.9% CAGR. Aerospace and defense propulsion is valued at $285B, growing to $394B by 2030. NASA and DARPA have prioritized nuclear thermal propulsion for crewed Mars missions. The Navy’s 30-year shipbuilding plan and Columbia-class program represent $100B+ in modernization demand.
Strategic Advantages
Fusion-fission design eliminates meltdown risk and toxic off-gas production. Direct energy conversion removes the noise, weight, and failure-mode constraints of steam-loop systems. Platform-agnostic modular architecture. Technology assessed by DARPA and Lockheed Martin Skunk Works as “far advanced compared to any national lab or defense contractor R&D.”
Execution Readiness
Core plasma technology (CLA-2004) under development with parallel laser integration track. Seven incorporated technologies are mature; size reduction achievable over 4-year R&D program. Naval application aligned with Virginia-class and Columbia-class timelines. Aerospace integration planned for NC-9’s Eagle-S and Space Eagle programs.
