Kleos Space S.A. confirmed its Observer Mission (KSF3) satellites is manifested to launch on the Transporter-6 SpaceX mission NET October 2022. The Observer Mission satellites will be deployed into a Sun Synchronous orbit from Cape Canaveral Space Force Station in Florida. Spaceflight Inc. contracted the launch and integration services from ISILAUNCH on behalf of Kleos.

Equipped with AIS, VHF, and X-Band payloads, the four satellites will expand Kleos' data collection capability by up to an additional 119 million km² per day. They also enable Kleos to increase its average daily revisit rate over the 15-degree latitude area of interest to around five times a day. As a Spaceflight Inc. customer, Kleos' KSF3 mission was originally booked for a mid-2022 launch, but was moved to SpaceX's Transporter-6 mission and will deploy from an ISILAUNCH integrated port after Spaceflight encountered a vibration issue with their original deployment method.
