Then the Zenith end of SKKO would be soft docked to Nauka and bolted down. The three passive payload adapters and the one active payload adapter (i.e. active remote sensing payload like [[Mir|MIR]] [[Priroda]]'s [[Priroda#Travers Synthetic Aperture Radar|Travers Synthetic Aperture Radar]]) would then be outfitted. The SKKO was derived from the setup used on the Priroda module.<ref>{{Cite web |last=Roscosmos |title=MLM-U Structure diagram |url=https://everydayastronaut.com/wp-content/uploads/Prelaunch-Preview/Roscosmos/Rendering_Nauka_incuding_components_attached_post_Nauka_Docking-768x370.jpg |website=Everydayastronaut.com}}</ref> SKKO will be launched inside the Progress spacecraft and transferred to a temporary storage location inside one of the station modules.
