Electron is a two-stage, partially reusable orbital launch vehicle developed by Rocket Lab, an American aerospace company with a wholly owned New Zealand subsidiary.[14][15] Electron services the commercial small satellite launch market.[16] It's the third most launched small-lift launch vehicle in history. Its Rutherford engines are the first electric-pump-fed engine to power an orbital-class rocket.[17] Electron is often flown with a kickstage or Rocket Lab's Photon spacecraft. Although the rocket was designed to be expendable, Rocket Lab has recovered the first stage twice and is working towards the capability of reusing the booster.[18] The Flight 26 (F26) booster has featured the first helicopter catch recovery attempt. Rocket Lab has, however, abandoned the idea of catching Electron.

In December 2016, Electron completed flight qualification. The first rocket was launched on 25 May 2017,[19] reaching space but not achieving orbit due to a glitch in communication equipment on the ground.[20][21] During its second flight on 21 January 2018, Electron reached orbit and deployed three CubeSats.[22] The first commercial launch of Electron, and the third launch overall, occurred on 11 November 2018.[23] Since then, Electron has launched successfully 46 times, with an additional 4 failures, for a grand total of 50 launches.
