The Dupuy de Lôme was designed by Thales Naval France on civilian standards. 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. File:Dupuy de Lome-IMG 9491.jpg|Dupuy de Lôme moored in Brest harbour in 2011
