Elektro-L4 was launched into orbit in 2011 using a Zenit-3F launch vehicle. In late 2015 a second satellite, Elektro-L 2, was launched from the Zenit-3F launch vehicle. The Elektro-L 3 launch, which was rescheduled from 2018, was launched in December 2019 using the Proton-M rocket Block-DM-03. At 165.8° east longitude, it operates. The fourth satellite, Elektro-L 4, was supposed to be launched in 2021, but it was postponed until 2023.
