Revenue model

1. Radiation-as-a-Service (RaaS): Fuse generates near-term revenue by providing radiation effects testing services to government and commercial customers using its fusion radiation source (FAETON). Customers book 'shots' on the machine to test defense platforms, space hardware, semiconductors, and materials for survivability in radiation environments. Pricing is quote-based given the bespoke nature of each test campaign.
2. Government Defense Contracts: Fuse Federal Enterprise LLC secures contracts with U.S. government agencies for radiation testing and nuclear effects evaluation supporting national defense programs. Major awards include selection for the MDA SHIELD IDIQ program (ceiling $151B) supporting the Golden Dome missile defense initiative, and AFWERX SBIR contracts with the U.S. Air Force.
3. Public-Private Partnership R&D: Fuse partners with U.S. Government through CRADA agreements (Sandia National Labs, Los Alamos National Lab) to develop next-generation pulsed power technologies. These partnerships involve shared funding and resource contributions toward mutual national security and fusion commercialization objectives.

Core offering

Fuse designs, builds, and operates proprietary pulsed power fusion generators (TITAN, FAETON) and provides Radiation-as-a-Service (RaaS) for nuclear effects and radiation survivability testing to U.S. defense agencies, commercial aerospace and space companies, semiconductor manufacturers, and energy companies. The company also advances MagLIF-based fusion energy toward commercial deployment, with a wholly-owned subsidiary (Fuse Federal Enterprise, LLC) focused on U.S. Government customers.

Product overview

Fuse is a nuclear fusion company developing pulsed power generators and fusion radiation sources for both commercial fusion energy and near-term nuclear effects testing revenue. The product portfolio centers on three generations of pulsed power machines: TITAN (1 TW Impedance Matched Marx Generator), Z-STAR (15 TW MagLIF generator linking 16 TITANs), and APEIRON I (500+ TW fusion pilot plant). Complementing these are FAETON and FAETON-X dense plasma focus devices that generate neutrons for radiation testing services. The ICECAP facility combines FAETON-X DPF with Flash X-Ray sources for comprehensive radiation effects survivability testing. Fuse Federal, the company's government subsidiary, commercializes these capabilities for defense and national security customers through Radiation-as-a-Service (RaaS) offerings.

Products and services

• TITAN TITAN is a 1 TW Impedance Matched Marx Generator (IMG) - the world's first high-energy, high-power IMG. It serves as the essential MagLIF building block and fusion energy driver, consisting of over 40,000 parts, 20,000 liters of oil, 640 liters of deionized water, weighing approximately 22 tons. It delivers peak power of 1 TW with 90% energy efficiency and is used to demonstrate the IMG-based pulsed power architecture for fusion energy and radiation effects testing.
• FAETON FAETON is a dense plasma focus (DPF) fusion radiation source - the first-of-its-kind fusion generator licensed for neutrons in the U.S. Rated at 100 GW power, it generates 1+ trillion neutrons per shot, supporting radiation effects testing for defense, space, and commercial customers.
• ICECAP ICECAP is a combined radiation testing facility that pairs FAETON-X dense plasma focus neutron source with a Flash X-Ray (FXR) source and a FOSS Model 812 Co-60 irradiator. It offers combined-environment survivability testing for defense, space, and semiconductor customers. Accepting bookings for radiation effects survivability testing.
• Radiation-as-a-Service (RaaS) Radiation-as-a-Service is Fuse's near-term revenue offering providing nuclear effects and radiation survivability testing to U.S. defense agencies, commercial aerospace and space companies, semiconductor manufacturers, and Fortune 500 energy companies. Customers book 'shots' on FAETON and ICECAP machines to test defense platforms, space hardware, semiconductors, and materials for survivability in radiation environments. Same-day data turnaround is enabled through automated data acquisition.
• Fuse Federal Enterprise, LLC Fuse Federal Enterprise, LLC is a wholly-owned subsidiary of Fuse Energy Technologies Corporation focused on U.S. Government customers. It provides radiation services to U.S. government agencies supporting critical defense and energy initiatives, including radiation effects testing for national security applications. Engages in SBIR, AFWERX, and IDIQ contract vehicles (including selection for the $151 billion MDA SHIELD IDIQ program).

Partnerships

Four partnerships are on record, tiered flagship and core.

• Missile Defense Agency (MDA)flagshipStrategic or Co-development Partner · 2 February 2026Fuse Federal Enterprise LLC was selected for the Missile Defense Agency's $151 billion SHIELD IDIQ program supporting the Department of War's Golden Dome initiative. Fuse Federal's radiation testing capabilities accelerate performance validation and strengthen system resilience for contested defense applications in the $151B ceiling program. This represents Fuse's largest announced government contract opportunity.
• Los Alamos National Laboratory (LANL)coreStrategic or Co-development Partner · 16 July 2025Fuse signed a CRADA with Los Alamos National Laboratory to advance pulsed power technologies for fusion energy and national security. The partnership combines LANL's 80-year experience in high-energy density physics, plasma theory, computational modeling, and materials science with Fuse's novel pulsed power and z-pinch systems. LANL evaluates Fuse's current and future hardware designs and cooperatively develops target designs tested by both LANL and Fuse plasma, radiation, and energy experts. This supports NNSA's stockpile stewardship mission and advances commercial fusion.
• Fifth Gait TechnologiescoreStrategic or Co-development Partner · 8 April 2025Fifth Gait Technologies completed a rigorous 140+ shot test campaign on Fuse's FAETON fusion radiation source, validating FAETON's performance at consistently 2.5×10^10 neutrons with a maximum yield of 8×10^10 neutrons. Fifth Gait served as a key testing validator, demonstrating FAETON's viability for national security and space applications. Results submitted to a top-tier scientific journal for peer-review.
• Sandia National LaboratoriescoreStrategic or Co-development Partner · 23 July 2024Fuse Federal signed a CRADA with Sandia National Laboratories to accelerate development of next-generation pulsed power technologies critical for U.S. nuclear deterrent safety and reliability, as well as fusion energy advancement. The collaboration leverages Sandia's expertise in high-energy density physics and Fuse's novel IMG approach. Fuse's TITAN is inspired by Sandia's Z Machine. Dr. Daniel Sinars, Director of the Pulsed Power Sciences Center at Sandia, commented on the partnership.
