CycloKinetics, a newly launched U.S. defense propulsion company, has entered the aerospace market with a portfolio of advanced drop-in fuels designed for military aircraft, missiles, and rockets. The company said its fuels already operate across Army, Navy, and Air Force platforms after more than 15 years of work with the U.S. military.

The launch formalizes a dedicated defense-focused structure for the business as aerospace companies push for longer range, higher endurance, and more efficient propulsion systems. CycloKinetics positions its fuels as direct replacements for existing military and aerospace propellants without requiring major engine redesigns.

High-energy fuel systems

CycloKinetics develops high-energy propellants engineered to improve range, payload capacity, thermal performance, and endurance across defense and aerospace platforms. The company says its fuels integrate with current propulsion systems while delivering measurable performance gains in demanding operating environments.

“Building superior fuels has been our business for 15 years, and that work has earned us the trust of leading airlines and every branch of the U.S. military. Creating CycloKinetics as a dedicated defense entity is the logical outcome of that history; we now have the scale and operational depth to warrant the same structure,” said Mukund Karanjikar, CEO and founder of CycloKinetics.

The company’s flagship aviation fuel, CycloJP, serves as a replacement for Jet A, JP-5, JP-8, and JPTS fuels used across military and commercial aircraft. CycloKinetics says the fuel delivers higher energy density and stronger thermal stability than conventional aerospace fuels.

The company designed CycloJP for high-speed and high-altitude operations where temperature swings and engine stress can limit performance. CycloKinetics says the fuel maintains stability in extreme cold while supporting more efficient operation during long-duration missions.

The fuel also targets unmanned aircraft systems that require extended endurance and higher operational ceilings. Longer range and reduced fuel consumption remain critical priorities for surveillance and reconnaissance platforms operating in contested regions.

CycloRP focuses on launch vehicles and reusable rocket systems. The fuel acts as a replacement for RP-1 and RP-2 liquid rocket propellants widely used in the space industry.

CycloKinetics says CycloRP offers higher volumetric and gravimetric energy density, allowing rockets to carry heavier payloads without major propulsion changes. The company also claims the fuel produces cleaner combustion with lower soot formation inside engines.

Reduced soot buildup could help reusable launch providers lower maintenance demands and improve engine lifespan between launches. The company says cleaner-burning fuels may also support faster refurbishment cycles for reusable rockets.

CK-10 targets missile propulsion as a replacement for JP-10 fuel used in advanced weapons systems. CycloKinetics says the fuel improves combustion performance and increases energy density, helping missiles travel farther while improving standoff capability.

“Across defense and space, propulsion is no longer a background variable but a primary driver of mission capability,” Karanjikar said.

Indo-Pacific range focus

CycloKinetics linked its fuel development efforts to growing U.S. military concerns in the Indo-Pacific, where distance and logistics continue shaping operational planning. The company released a whitepaper arguing that advanced propellants could play a major role in sustaining American air superiority.

The company said higher energy density fuels could reduce reliance on mid-air refueling while extending aircraft range and mission endurance. CycloKinetics also emphasized domestic and distributed fuel production to reduce supply chain vulnerabilities during future conflicts.

“In the strategic competition with China, the ability to sustain and extend U.S. air superiority will depend on aircraft and munitions as well as the largely unseen forces, such as advanced propellants, that power them,” Karanjikar said.

He added that advanced fuels can reduce logistical vulnerabilities while improving operational reach for U.S. forces operating in contested environments.
