Launch Vehicle : Rocket Lab Electron.
https://en.wikipedia.org/wiki/Rocket_LabElectron is a two-stage launch vehicle which uses Rocket Lab's Rutherford liquid engines on both stages. The vehicle is capable of delivering payloads of 150 kg to a 500 km Sun-synchronous orbit, the target range for the growing small satellite market. The projected cost is less than US$5 million per launch.
The Rutherford engine uses pumps that are uniquely powered by battery-powered electric motors rather than a gas generator, expander, or preburner. The engine is also fabricated largely by 3D printing, via electron beam melting,[24] whereby layers of metal powder are melted in a high vacuum by an electron beam rather than a laser.
As of April 2016, the 22 kN (5,000 lbf) Rutherford engine for the second stage passed its firing tests. The first test flight took place on 25 May 2017 at 04:20 UTC from Mahia Peninsula in New Zealand's North Island. The rocket entered space but did not reach orbit.
