Kleos Space S. A announced the Kleos Patrol Mission (KSF2) satellites, planned to launch in January 2022, have been remanifested to launch on the SpaceX Transporter-4 mission scheduled for April 2022. Kleos is partnering with launch services provider Spaceflight Inc. to deploy its Patrol Mission (KSF2) satellites to a sun synchronous orbit. Originally scheduled for the SpaceX Transporter-3 mission in January 2022, Kleos' Patrol Mission launch was postponed when the Spaceflight orbital transfer vehicle tasked with launching and deploying Kleos' satellites experienced technical issues.

Spaceflight quickly identified an alternative launch option. Kleos' fourth satellite cluster, the Observer Mission (KSF3), is unaffected by the Patrol Mission delay and remains on track to launch in mid-2022.
