France launches first Syracuse IV telecommunications satellite.

An Ariane 5 rocket launched from the Guiana Space Centre placed France's new Syracuse 4A military telecommunications satellite in low orbit on 22 October.

The first of three Syracuse IV satellites designed by Airbus and Thales will become operational in nine months, seven months after it reaches geostationary orbit propelled by its Safran electric motor (the consumption of which is six times lower than a conventional motor) and two months of testing. Test centres of the Direction Générale de l'Armement , the French defence procurement agency, carried out stress tests to prepare for the vibration of the launch.

Syracuse IV produces a throughput three times higher (1.5 Gbit/sec) than Syracuse III by operating in two bands: X and Ka. Three satellites are to be placed in orbit: the second in 2022 and the third on an unknown date.

Over 400 new-generation ground stations are also to be delivered. Among the new systems connected will be the Phénix Multi Role Tanker Transport, Scorpion armoured vehicles, and the new Suffren nuclear attack submarine.

The total cost of the Syracuse IV programme is EUR3.6 billion (nearly USD4.2 billion).
