The Electron was manufactured by Rocket Lab with the first launch on 2017-05-25. Electron has 37 successful launches and 4 failed launches with a total of 41 launches. Electron is a two-stage orbital expendable launch vehicle (with an optional third stage) developed by the American aerospace company Rocket Lab. Electron is a small-lift launch vehicle designed to launch small satellites and cubesats to sun-synchronous orbit and low earth orbit. The Electron is the first orbital class rocket to use electric-pump-fed engines, powered by the 9 Rutherford engines on the first stage. It is also used as a suborbital testbed (called HASTE) for hypersonics research.
