On September 14, at 21:17:09 MSK, the launch of the Soyuz-2.1 b carrier rocket with the Fregat upper stage and 34 new spacecraft of the OneWeb satellite company was launched from the launch pad No. 6 of the launch pad No. 31 of the Baikonur Cosmodrome in the normal mode. This launch was already the tenth in the framework of the OneWeb joint program. This was reported by Roscosmos.

The sequential separation of nine groups of spacecraft (in the first — two, in the rest — four satellites) from the Russian upper stage was carried out in accordance with the program laid down by specialists of the Lavochkin Scientific and Production Association (part of the Roscosmos State Corporation). During the autonomous flight, eleven active sections were provided: three inclusions of the main propulsion system (the last one was for the purpose of delivering the upper stage to the "withdrawal orbit") and eight inclusions of the stabilization, orientation and launch propulsion system necessary for the safe separation of satellites.

Foreign customers of Glavkosmos (part of Roscosmos) have confirmed the fulfillment of contractual obligations. All devices are accepted for communication by the customer. Upon completion of the separation and separation of the spacecraft, the Fregat upper stage will be removed from Earth orbit, and the fireproof elements will be flooded in the uninhabited part of the Pacific Ocean.

The launch of the spacecraft was carried out by order of the European launch services provider Arianespace (OneWeb spacecraft launch operator) and Starsem under Glavkosmos contracts. It was carried out by the joint calculation of Roscosmos subsidiaries: the Progress Rocket and Space Center, the Lavochkin Scientific and Production Association, the Center for the Operation of Ground-based Space Infrastructure Facilities, Russian Space Systems, Glavkosmos, as well as foreign customers.

The Fregat upper stage ensures the effective performance of all tasks for launching one or several vehicles into working orbits or trajectories departing from the Earth. The entire process of removal is carried out autonomously, without interference from the Ground. The highest reliability and almost perfect accuracy of the launch provide the upper stage with undeniable competitive advantages in the global space launch market. This launch was the 100th for the Fregat upper stage.

OneWeb spacecraft are designed to create a space communication system that provides high-speed Internet access anywhere on Earth. Internet access via the OneWeb satellite system will be provided through 40 ground terminal stations that will be deployed on the Earth's surface.

OneWeb terminals will be autonomous, able to supply themselves with energy independently and well protected from the influence of adverse environmental factors. Each of them will be able to provide high-speed Internet access in its coverage area via Wi-Fi, LTE or 5G technologies. In addition, a licensed radio frequency range will be used or, where there is such a possibility, a public radio frequency range of Wi-Fi, LTE or 5G standards will be used.

The first OneWeb satellites were launched into orbit in February 2019 from the Guiana Space Center. In July 2021, the company announced that it plans to complete the deployment of a satellite constellation to provide global coverage by June 2022. According to OneWeb, the grouping in low Earth orbit will consist of 648 satellites.
