Russia's Roscosmos Federal Space Agency secured a contract with France's Arianespace and British OneWeb global broadband Internet service to launch 672 satellites between 2017 and 2019.
"This contract is the biggest in the history of providing launch services. And the choice of Soyuz carrier rockets is evidence of the high competitiveness of Russian space launch technology," Roscosmos head Igor Komarov said.
The project provides for 21 space launches, with an option for five more if the contract is prolonged for another year afterwards. Arianespace praised the Soyuz carrier rockets for their ability to launch satellites into the polar orbit necessary for providing the service.
"The unique capability of being able to achieve near polar orbit from multiple launch sites using a common launcher along with its proven industrial production were instrumental in the Soyuz selection as a key resource to deploy the constellation on schedule," Arianespace said in a press release.
The launches are planned to take place at the Baikonur launch site in Kazakhstan, at Russia's new Vostochnyy cosmodrome and at the French Guiana Space Centre.
