Falcon 9 rocket will deliver three-satellite SARah Constellation that will serve German Ministry of Defense

Hawthorne, CA – Space Exploration Technologies (SpaceX) will provide the launch services for Germany’s second-generation radar reconnaissance satellite system. The satellites, provided by OHB System AG and Astrium GmbH, will replace the current constellation and will be delivered to orbit by two Falcon 9 rockets in 2018 and 2019.

"SpaceX looks forward to working with OHB and Astrium, and we appreciate their confidence in SpaceX to reliably deliver these satellites to orbit,” said Gwynne Shotwell, SpaceX President and COO. “These missions are very meaningful for SpaceX as the first contracted for a European government.”

OHB will build two passive-antenna synthetic aperture radar (SAR) satellites, and Astrium GmbH will build a larger, phased-array-antenna satellite under contract for OHB. The three-satellite constellation will replace the current OHB-built five-satellite SAR-Lupe constellation.

The SARah 2/3 passive radar imaging satellites are being built for the German government by OHB as part of the three satellite SARah constellation, a follow-up to the SAR-Lupe radar sat constellation.  The SARah 1 satellite is being constructed by Airbus.  The SARah 2/3 satellites will mass about 1800kg.
