Kick Stage

Kick Stage

An optional apogee kick stage that can execute multiple burns to place numerous payloads into different, circularized orbits. It opens up significantly more orbital options, particularly for rideshare customers that have traditionally been limited to the primary payload’s designated orbit. Powered by Rocket Lab's 3D printed liquid propellant Curie engine capable of 120N of thrust and multiple burns.

Second Stage

Second Stage

Electron's second stage is powered by a variant of the Rutherford Engine providing improved performance in vacuum conditions.

Total Thrust 22 kN (5,000 lbf)

ISP 333 sec

Carbon Composite Materials

Carbon Composite Materials

Electron makes use of advanced carbon composite materials for a strong and lightweight flight structure.

Through an extensive research program, Rocket Lab has developed carbon composite tanks that are compatible with liquid oxygen, providing impressive weight savings.

Custom Cryogenic Valves and Helium Pressurization Systems

Custom cryogenic valves and helium pressurization systems were developed by Rocket Lab for ultimate efficiency and reliability.



Rocket Lab excels at producing high-performance miniature avionics and flight computer systems. The computing nodes make use of state-of-the-art FPGA architecture, allowing massive customization of function while retaining hardware commonality.
