It was reported, that all the missions of the vessel lie in detection and analysis of the signals of all types including those received by the satellites.
It was noted that Dupuy de Lome has entered the Black Sea for intelligence operations multiple times – in 2006, 2010, 2014 and 2015. Radio- and electronic intelligence systems installed on the ship allow detection, direction finding and technical analysis of various sources within the range from 300 MHz to 90 MHz. Besides, the ship can intercept, find the direction and tap the signals of communications systems (including satellite) within the range from 30 kHz to 100 kHz. The equipment of the ship is able to intercept modern types of transmission including messages on e-mail and phone conversations.
The vessel was commissioned in April, 2006. It can travel at 16 knots. The crew consists of 30 sailors and 80 operators of intelligence equipment.
It should be noted that the French vessel will not participate in Sea Breeze – 2019. It will be interested in Russian vessels tracking USS Carney. To cut it short, this is wiretapping of a wiretap. Dupuy de Lome will monitor the active stage of drills.
