On 25 November 2025, at 16:42 MSK (13:42 UTC) crews of the Air and Space Forces conducted a successful launch of an Angara 1.2 launcher from the launch pad 1 of the launch complex 35 of the Plesetsk test site. The ministry of defense published the video of the launch.

The launcher and its AM boost stage delivered into orbit three satellites, which are likely to be designated Cosmos-2597, Cosmos-2598, and Cosmos-2599. The satellites received international designations 2025-273A, 2025-273B, and 2025-273C and NORAD numbers 66647, 66648, and 66649 respectively. After maneuvers the satellites were deployed in nearly circular orbits with altitude of about 1500 km and inclination of 82.5 degrees.

The satellites are believed to be Rodnik communication satellites. Previous launch of three Rodnik satellites took place in March 2025.
