Syracuse 4A



The 8,492-pound (3,852-kilogram) Syracuse 4A spacecraft, also built by Thales Alenia Space, will provide communications services for the French military. The satellite will relay secure communications between French military aircraft, armored ground vehicles, and naval vessels, including submarines.

The Syracuse 4 program replaces the Syracuse 3 generation, which comprises two French satellites launched in 2005 and 2006, and a joint spacecraft with Italy that went into orbit in 2015. The Syracuse satellites provide relay services for French military forces deployed and on the move in areas outside the each of terrestrial communications.
