Summary
Sentinel-3B launched on an Eurockot Launch Services Rokot/Briz-KM from 133/3 (133L), Plesetsk Cosmodrome, Russian Federation on April 25, 2018. It was Eurockot Launch Services's 14th launch, 1st this year and humanity's 5,745th orbital launch attempt. It was the 28th Rokot/Briz-KM flight and the 1st this year. The payload was bound for Sun-Synchronous Orbit (SSO). Sentinel-3B, one of 2 catalogued objects, reached a 802 × 819 km orbit inclined 98.6°. 2 objects from this launch are catalogued, one of them a payload.

About this launch
Sentinel-3B is the second in a constellation of earth observation satellites developed by ESA to provide near real time data for the Global Monitoring for Environment and Security Program. Sentinel-3B contains a temperature scanner, colour instrument and altimeter for monitoring the sea and land. The satellite focuses on providing accurate data about the oceans and in addition also provides information about wildfires and vegetation.
