The launch agreement was completed through SES’ affiliate company SES-SL. The first of these new launches will take place in 2015. SpaceX won a previous launch agreement with SES in March 2011 to place the SES-8 satellite into orbit in 2013.

   SES President and CEO Romain Bausch said all four Falcon missions would support the enhancement of SES’ global fleet of satellites.

   “SES was the first leading commercial satellite operator to place a launch contract with SpaceX and we eagerly await the launch of SES-8 in 2013,” Bausch said in a statement. “This new contract is testimony to our belief in SpaceX’s product and technical abilities. It also confirms SES’ priority for diversification of launch service providers and for securing timely access to space. We look forward to a long-term relationship with SpaceX.”

   “We’re very pleased to add these three additional launches to our agreement with SES,” SpaceX President Gwynne Shotwell said in a separate statement. “It’s a strong endorsement of our launch capabilities and continues an outstanding partnership between our companies.”
