The Russian Defense Ministry announced the launch April 7, and U.S. military tracking data later confirmed the mission placed a single payload into orbit. (...)

The Lotos S1 satellites are built by KB Arsenal, a Russian military contractor in Saint Petersburg, in partnership with TsSKB Progress. According to the manufacturer, the Lotos S1 satellites weigh around 13,000 pounds (6,000 kilograms) fully fueled at launch.
The Lotos satellites are part of Russia’s Liana military intelligence network, working in tandem with Pion-NKS satellites capable of collecting radar images of ships. The Lotos satellites host antennas to intercept radio signals that can be used to find the positions of military vehicles, including naval vessels.
Russia’s Liana electronic intelligence program is a successor to Russia’s Cold War-era Tselina, US-A, and US-P military satellites. The first Lotos test satellite launched in 2009, and five operational Lotos S1 satellites have launched since 2014.
