Flight 199 is the 55th Ariane 5 launch and the fifth in 2010. An ARIANE 5 ECA (Cryogenic Evolution type A), the most powerful version in the ARIANE 5 range, will be used for this flight.
Flight 199 is a commercial mission for Ariane 5. The L557 launcher is the first in the A5ECA family to be delivered by AIRBUS DEFENCE AND SPACE ST to Arianespace as part of the PB production batch. The PB production contract was signed in March 2009 to guarantee continuity of the launch service after completion of the PA batch comprising 25 A5ECA launchers, the last of which was launched on 26th November 2010. The PB production batch comprises 35 A5ECA launchers and covers the period from 2010 to 2015. L557 is consequently the thirtieth complete launcher to be delivered to Arianespace, integrated and checked out under AIRBUS DEFENCE AND SPACE responsibility in the Launcher Integration Building (BIL).
In a dual-payload configuration using the SYLDA 5 “A” system and a long pattern fairing (total height: 17 m), the launcher is the satellites HISPASAT 1E in the upper position and KOREASAT 6 in the lower position.
