Flight VA255 – SES-17 / SYRACUSE 4A | Ariane 5 Launch | Arianespace

For its 11th launch of the year, the second using Ariane 5, Arianespace orbited two geostationary satellites: SES-17, a telecommunications satellite operated by SES, and SYRACUSE 4A, a telecommunications satellite developed for the French Ministry of the Armed Forces. Thales Alenia Space manufactured both.

For its 111th launch, Ariane 5 executed the highest performing flight by any launcher to geostationary transfer orbit: with two payloads on board, SES-17 and SYRACUSE 4A, with a total mass of 10264 kg, Ariane 5 achieves a world record for injection into this orbit. This launch also included a 1.5 m extension placed under the long fairing in order to adapt it to the specific needs of its two passengers.
