SYRACUSE 4A

Syracuse 4A and 4B are designed to carry Ka- and X-band payloads.

SYRACUSE 4A will support NATO and European-led operations and connect French armed forces deployed at sea, in the air, and on the ground.

Syracuse 4A is built on the all-electric Spacebus NEO platform and features cyber-defense and data encryption technologies supplied by Thales.

SYRACUSE 4A and SYRACUSE 4B manage X-band and Ka-band resources to provide increased operational flexibility across their coverage area.

Thales Alenia Space is responsible for SYRACUSE 4A, which is based on the 100% electric SpaceBus Neo platform, and for the two payloads.

SYRACUSE 4B embarks the same payload as SYRACUSE 4A, with SYRACUSE 4A’s payload built by Thales Alenia Space and key components provided by Airbus.

SYRACUSE 4A is designed with X- and Ka-band payloads and a design life of 15 years.

SYRACUSE 4A was launched on 23 October 2021 as a passenger on Ariane 5 mission VA255 alongside SES-17.

The two VA255 payload masses were provided as 6,411 kilograms for SES-17 and 3,852 kilograms for SYRACUSE 4A.

Ariane 5 mission VA255 launched two geostationary-transfer-orbit satellites, SES-17 and SYRACUSE 4A.

SYRACUSE 4A uses multiple Safran PPS®5000 electric thrusters for in-orbit propulsion.

SYRACUSE 4A is a French military communications satellite manufactured by Thales Alenia Space for the Direction Générale de l'Armement (DGA).

SYRACUSE 4A has a reported mass of 3,852 kilograms.

Ariane 5 successfully launched a mission on 2021-10-23 placing the SES-17 communications satellite for SES and the Syracuse 4A communications satellite for France’s military into geostationary transfer orbit.
