BERN, Switzerland, February 1, 2013

Sea Launch AG announced today that approximately 40 seconds after liftoff of the launch of the Intelsat 27 spacecraft, all telemetry was lost indicating a loss of mission. The spacecraft, built by Boeing Satellite Systems was launched on a Zenit-3SL launch vehicle from the equator on the ocean-based Odyssey launch platform, positioned at 154 degrees West longitude.

Sea Launch will establish a Failure Review Oversight Board to determine the root cause of the incident and will provide additional information, as it becomes available, on the Sea Launch website at: www.sea-launch.com
