A Proton rocket which was intended to launch the JCSAT-11 satellite into a geostationary transfer orbit lifted off and successfully completed its first stage burn, but the second stage failed leading to loss of the rocket and satellite.

The launch vehicle was a Proton M booster with a Breeze M upper stage. More than 300 Proton rockets have been launched, all from the Baikonur Cosmodrome in Kazakhstan. Following the launch failure, Kazakhstan suspended the launch of Proton rockets from Baikonur, Interfax news agency reported.

JSAT Corporation immediately placed an order with Lockheed Martin, the satellite manufacturer, for an identical replacement satellite based on the A2100AX design.
