Russia’s Defense Ministry reported the successful launch of a Soyuz-2.1b medium-class carrier rocket from the Plesetsk Cosmodrome in the Arkhangelsk region on 13 September, according to Russian news agency Interfax.

The launch deployed two spacecraft into orbit: a military satellite serving Defense Ministry interests and the Mozhaets-6 educational-research apparatus. Space forces personnel from Russia’s Aerospace Forces conducted the operation.

“On 13 September 2025, from the Plesetsk Cosmodrome (Arkhangelsk region), a combat crew of the Aerospace Forces’ space troops conducted the launch of the medium-class Soyuz-2.1b carrier rocket with a spacecraft in the interests of the Defense Ministry of Russia and the educational-research spacecraft Mozhaets-6,” the ministry stated, according to the report.

The Mozhaets-6 satellite represents an academic project developed by a student at the Mozhaisky Military Space Academy. The Defense Ministry specified that the apparatus was “designed for working out astronavigation algorithms.”

The launch marks another deployment from Plesetsk, Russia’s primary military launch facility located approximately 800 kilometers north of Moscow. The Soyuz-2.1b rocket serves as a workhorse for Russian military and commercial satellite deployments.

No details were provided regarding the military spacecraft’s specific mission or operational parameters.
