Letara secures $16M to expand hybrid propulsion from satellite thrusters to large rocket systems

Funding and Expansion

Letara, a Sapporo-based startup specializing in hybrid propulsion systems, has secured ¥2.6 billion (~$16 million) in new funding. This investment will enable the company to broaden its focus from developing hybrid thrusters for small satellites to creating large rocket systems for the space, defense, and security sectors.

The funding round was co-led by Headline Asia, JIC Venture Growth Investment, and Incubate Fund, with additional participation from strategic investors including NES Corporation, Toyoda Gosei, and Frontier Innovations, an investment fund backed by JAXA.

Technological Approach

Letara's core technology involves a hybrid rocket design that separates solid fuel from the liquid oxidizer required for combustion. The company utilizes inexpensive and widely available materials like plastic and rubber as solid fuel.

Letara has developed a proprietary manufacturing process to mix, shape, and compress these materials, ensuring reliable ignition and consistent burning. This system aims to deliver more thrust with less waste compared to traditional hybrid rockets that often use paraffin wax.

Addressing Market Challenges

The company's expansion is driven by the goal of overcoming key limitations in hybrid propulsion, specifically generating sufficient thrust, maintaining performance, and controlling combustion. If successful, Letara could tap into a growing market; the global hybrid rocket propulsion market is projected to reach $2.6 billion by 2032, up from $848 million in 2024.
