Rocket "Proton-M" successfully launched from Baikonur
A Proton-M launch vehicle launched the Ekspress AMU3 and Ekspress AMU7 satellites from the Baikonur Cosmodrome in Kazakhstan, on 13 December 2021, at 12:07 UTC (17:07 local time, 15:07 MSK). The Ekspress AMU3 and Ekspress AMU7 spacecraft (Экспресс-АМУ3, Экспресс-АМУ7) are Russian telecommunications satellites.

582 seconds after the launch, the head unit (a bundle of the upper stage and two spacecraft) in the normal mode separated from the third stage of the carrier. For the flight of the "Proton-M" rocket, a typical route is used with highlighted areas of fall of detachable parts of a space rocket. This path provides an inclination of the reference orbit of 51.55 °.
Further launching of spacecraft into the target orbit with a minimum altitude of 18.7 thousand kilometers and a maximum of 52.8 thousand kilometers will be ensured by five starts of the main engine of the Breeze-M upper stage. The total duration of the launch from the launch of the launch vehicle to the separation of the first Express-AMU7 spacecraft will be 17 hours 50 minutes, for the second Express-AMU3 - 18 hours 7 minutes.
Ekspress AMU3 satellite
The Proton-M launch vehicle and the Briz-M upper stage have been developed and are serially manufactured by the State Research and Production Space Center named after M.V. Khrunichev (part of Roscosmos). Since 1965, 426 launches of various modifications of the Proton rocket have taken place. The use of the Breeze-M upper stage as part of the Proton-M rocket makes it possible to increase the payload mass delivered to the GSO up to 3.5 tons, and more than 6 tons into the transfer orbit. The first launch of the Proton-M - Breeze-M complex took place on April 7, 2001.
Ekspress AMU7 satellite
Spacecraft "Express-AMU3" and "Express-AMU7" are designed to provide a wide range of communication and broadcasting services in the territory of the Russian Federation, to provide fixed and mobile communications, to provide TV and radio broadcasting services, broadband high-speed access to information resources and other applications.
