The University Würzburg Experimental Satellite 4 (UWE-4) is the most recent project within the UWE CubeSat family. This 1U (one unit) CubeSat will incorporate for the first time in the UWE program a propulsion system. The satellite is scheduled for launch on board a Soyuz-2 mission using a Fregat upper stage in December 2018.
