Soyuz-2-1v launches classified payload

Military personnel in Plesetsk opened the 2024 Russian orbital launch campaigns with the liftoff of a Soyuz-2-1v rocket on February 9 carrying a payload for the Ministry of Defense. It was the 12th mission of the light-weight Soyuz variant since its introduction in 2013.

According to the official statement of the Russian Ministry of Defense a Soyuz-2-1v rocket lifted off on Feb. 9, 2024, at 10:03 Moscow Time, from Plesetsk carrying spacecraft for the Ministry of Defense. Unusually, the liftoff took place exactly at the same time as the previous launch of the Soyuz-2-1v rocket on Dec. 27, 2023.

Standard reports distributed by the state-controlled media also said that the spacecraft had been successfully inserted into its planned orbit and that it had been taken under control by ground assets of the Russian Air and Space Forces, VKS. The spacecraft maintained stable communications with ground control and its systems functioned nominally, according to the military. In the meantime, Roskosmos identified the new satellite as Kosmos-2575.

Based on the notifications to the air and sea traffic issued by the Russian authorities ahead of the launch, it appeared that the rocket ascended along the usual ground track required to reach orbit with an inclination of around 97 degrees toward the Equator.

Within hours of the Russian launch, the US Space Force published orbital elements for two objects originated on Feb. 9, 2024:

Orbital period
91.64 minutes
96.76 degrees
348.8 kilometers
361.1 kilometers
91.60 minutes
97.76 degrees
348.3 kilometers
357.8 kilometers

As expected, the orbit of the newly launched satellite appeared to be similar to that of a spacecraft orbited on Dec. 27, 2023.
