A heavy-lift booster Ariane-5 of the European Space Agency successfully put into orbit two communication satellites on Sunday, French company Arianespace reported.
The rocket has been launched from the Kourou spaceport in French Guiana.
The new satellite SYRACUSE-4A weighing more than 3,8 tonnes is aimed to allow all of France's armed forces across the globe to communicate quickly and securely.
The French air and space force spokesman Colonel Stephane Spet said: ”The satellite is designed to resist military aggression from the ground and in space, as well as interference,"
The other satellite SES-17 with high capacity was created by the Luxembourg company SES S.A. The vehicle weight is 6,4 tonnes and it will provide communication coverage for the French aircraft in North and South America.
The experts said that the space satellites are protected against electromagnetic pulses which could come from a nuclear blast.
In March the French military conducted the first exercises to test its capacity to defend space vehicles. The military officials called them "first space tests for the French army and even a first in Europe".
