The Dupuy de Lôme (A759), named after the 19th century engineer Henri Dupuy de Lôme, is a ship designed for the collection of signals and communications beyond enemy lines, which entered the service of the French Navy in April 2006. In contrast to the Bougainville, the ship that she replaced, the Dupuy de Lôme was specifically designed for sea intelligence, pursuant to the MINREM project (Moyen Interarmées Naval de Recherche ElectroMagnétique, "Joint Naval Resources for Electromagnetic Research").


The Dupuy de Lôme was designed and built by Royal Niestern Sander shipyards in Delfzijl, The Netherlands with yardnumber 816. The Thales Group|Thales Naval France has designed the electromagnetic intellegence part of the vessel. She provides a 350-day-operational availability a year, out of which 240 can be spent at sea. The ship is operated by two Navy crews, each composed of 33 sailors and 33 technicians, and an optional complement of up to 38 specialists, depending on the mission. The specialised personnel operates under the Direction du renseignement militaire.


On 21 June 2015, Dupuy de Lôme entered the Black Sea along with USS Laboon (DDG-58) as part of NATO's presence missions following the Annexation of Crimea by the Russian Federation.[1]
