Rutherford is a liquid-propellant rocket engine designed by aerospace company Rocket Lab [8] and manufactured in Long Beach, California. [9] The engine is used on the company's own rocket, Electron. It uses LOX (liquid oxygen) and RP-1 (refined kerosene) as its propellants and is the first flight-ready engine to use the electric-pump-fed cycle.
[35] [40] Later, Rocket Lab abandoned the plan to catch the stage with a helicopter, and will use ocean landing instead. One recovered Rutherford engine passed five full-duration hot fire tests and is declared ready to fly again. [41] Rocket Lab's 40th Electron mission successfully reused a refurbished Rutherford engine from a previous flight ...

Rocket Lab's Electron Rocket The Rutherford engine uses pumps driven by battery-powered electric motors rather than a gas generator , expander , or preburner . [ 107 ] The engine is fabricated largely by 3D printing , using electron beam melting , [ 108 ] whereby layers of metal powder are melted in a high vacuum by an electron beam. [ 109 ]

As of December 2020, the only rocket engines to use electric propellant pump systems are the Rutherford engine, [2] ten of which power the Electron rocket, [2] and the Delphin engine, five of which power the first stage of Astra Space's Rocket 3. [3] On 21 January 2018, Electron was the first electric pump-fed rocket to reach orbit. [4]
In June 2020, with a new Electron launch vehicle built every 18 days, Rocket Lab was planning to deliver monthly launches for the remainder of 2020 and into 2021, including the company's first launch from Wallops LC-2 in 2023 and a mission to the Moon for NASA aboard Electron and Rocket Lab's spacecraft bus platform Photon in 2022.

The same day, the Neutron page on Rocket Lab's website was updated specifying the thrust of the nine Archimedes engines used on the first stage as 5,960 kN (1,340,000 lbf) at sea level and a maximum thrust of 7,530 kN (1,690,000 lbf) and the upper stage's single vacuum optimized Archimedes at 1,110 kN (250,000 lbf).
