It was Russian Space Forces's 157th launch, 5th this year and humanity's 7,374th orbital launch attempt. It was the 26th Soyuz 2.1b Fregat flight and the 1st this year. The payload was bound for Medium Earth Orbit (MEO). Its tracked orbit, from September 3, 2026, was 19,157 × 19,180 km inclined 64.8°.

Glonass-K are the third generation of satellite design for GLONASS satellite navigation system. GLONASS is a Russian space-based navigation system comparable to the similar GPS and Galileo systems. This generation improves on accuracy, power consumption and design life. Each satellite is unpressurized and weighs 935 kg, and has an operational lifetime of 10 years.
