A759 Dupuy de Lôme - hosting MINREM

The Dupuy-de-Lôme was launched at the end of March 2004. It was placed at the disposal of the Military Intelligence Directorate (DRM) and armed by the French Navy in October 2005. The French Navy armed and implemented the new MINREM (joint naval electromagnetic research facility) in October 2005, for admission on July 1, 2006 Designed and optimized in order to meet intelligence needs from the sea, the Dupuy-de-Lôme is placed at the disposal of the military intelligence department (DRM), which defines its missions and exploits its production for the benefit of the various armies. Dupuy-de-Lôme is assigned to Brest on July 1, 2006.

Thales was selected by the French Defence Procurement Agency (DGA) on January 2002 as Prime contractor for the future French Joint SIGINT ship Dupuy de Lôme hosting the MINREM (Moyen Interarmées Navalisé de Renseignement d'origine Electro-Magnétique) payload. Thales Naval France and Compagnie Nationale de Navigation (CNN) are the Prime contractors, CNN through its Compagnie Maritime Nantaise subsidiary supplying the ship platform, and Thales Communications the complete Intelligence Collection payload (COMINT, ELINT, IT systems for Intelligence, and internal and Externalship communications). The Dupuy de Lôme was handed over to the DGA on 15 December 2005, and accepted by the French Navy on the same day.

Displacing over 3000 tons, the Dupuy de Lôme is 102 m long and features living and work areas designed for maximum crew and operators efficiency and comfort. The high level of system automation makes it possible to be operated with a limited crew of 30 members. The MINREM payload provides high-performance strategic Intelligence collection and analysis capacities with the integration of state-of-the-art COMINT and ELINT sensors, and real-time information system for the interception, monitoring, direction finding, signal analysis and recording of all radar and Radio-communications signals. The support services will ensure vessel availability meeting or exceeding 350 days per year.

The new MINREM payload will be a key asset of the France's Joint Forces'C3I system, performing Intelligence collection missions in all waters from peacetime to crisis and war time, operated by the France's Directorate of Military Intelligence (DRM). The MINREM payload is based on High sensitivity COMINT (XPLORER), Satellite and ELINT sensors providing precise and timely Intelligence information for detection, interception, location and identification of all Communication and Radar signals from HF to SHF frequency bands, including the most complex waveforms. THe Wideband signal acquisition and analysis (PAC) sensors are for listening-in and real-time or off-line signal analysis. A Comprehensive IT system for Intelligence collection and exploitation, providing interoperability with the French Intelligence chain. The Open system and sensors architecture will allow easy upgrades through technology insertion.

Thales added-value:

  • Thales' expertise in Prime-contractorship and system engineering
  • Strong program management ensuring the challenging delivery on time and in the budget constraints.
  • Innovative solutions for the demanding payload performances (wideband COM Direction Finding and Signal analysis sensors able to cope with most agile threats, state-of-the-art satellite interception solution, modern ELINT capacity)
  • Comprehensive shipboard internal and Externalcommunications system
  • Integrated Logistic Support

The support services will ensure vessel availability meeting or exceeding 350 days per year.

The operation and maintenance of the ship by a team reduced to 30 people are made possible by the application of innovative principles in the French Navy. An integrated system making it possible to reduce the driving team to a shift supervisor and a watchman, the absence of a machine shift making it possible to reduce the "energy-propulsion" service to a team of 7 people dedicated solely to maintenance. A computerized maintenance management system (CMMS) to lighten administrative tasks. taking into account in the design, good accessibility to the installations and adapted handling means allowing to reduce the time of maintenance operations. The activity rate of MINREM will be high (240 days) thanks to the arming of the ship by two crews. Its technical availability also (350 days / year) thanks to an innovative operational maintenance contract.

Stanislas Charles Henri Dupuy de Lome was born at the Castle of Soye Ploemeur near Lorient, Morbihan October 15, 1816 and died in Paris on 1 st February 1885, is a marine engineer and French politician. After graduating from École Polytechnique, he went to England to study the latest improvements in naval construction. In 1844 he published a plea in favor of metal construction, Memoir on the construction of iron buildings. He is the author of many inventions in the field of naval construction: he built the first high-speed steamship in the world, the Napoleon , launched in 1850. Then he built the first oceanic war battleship,The Glory (1858-59). During the war of 1870, he ensured the construction of balloons during the siege of Paris. At the end of his life, he studied the construction of the first truly operational submarine, the Gymnote. He was elected member of the Academy of Sciences in 1866. He was deputy for Morbihan from 1869 to 1870 and irremovable senator from 1877 to 1885.

Two other naval vessels have already borne the name of Dupuy de Lôme.

An armored cruiser (1890 - 1910), started in Lorient on July 4, 1888, and floated on October 27, 1890. It was present on June 20, 1895, with the Hoche and the Surcouf during the inauguration of the canal de Kiel. In 1897, he joined the Baltic naval division to replace the Bruix damaged. He was integrated into the North squadron from January to October 1898. We find him in Kronstadt in May 1902, where he bears the mark of the President of the Republic Emile Loubet. After a big refit in Brest, he made a stay in Morocco, and arrived September 14, 1909 in Lorient from Tangier. It was then placed in normal reserve on 22, then in special reserve on 9 November. Decommissioned on February 1, 1910, she was no longer used thereafter. On July 11, 1911, it was acquired by the Peruvian Navy. From August 23, 1911 to April 1912, a period of work took place. In May 1912, the Peruvian government asked to delay delivery. On September 19, 1912, passed under the Peruvian flag and he was renamed Commander Elias Aguirre.

But will never be delivered, however, following the entry into the war. In October 1914, the Peruvian crew was disembarked (he returned to Peru by the Peruvian cargo ship Urumba ), the ammunition was unloaded and the cruiser brought to the bottom of the port of Lorient where it remained unused, but resumed its baptismal name. The guns were landed in 1915 and sent to Ruelle for transformation for the benefit of the land artillery. After the war, he was left deprived of his weapons and his approvals at the bottom of the citadel of Port Louis, sometimes returning when there was room to anchor in the harbor of Pan-Mané.

In 1918, it was sold to the Belgian government. She then left Lorient, under the Belgian flag, on August 30, 1918 for Bordeaux where she was transformed into a freighter from August 1918 to December 1919. He left Bordeaux on December 27, 1919, under the name of Péruvier , and set sail for Cardiff where she took 4,000 tonnes of hard coal for Brazil. On June 5, 1920, she was damaged, with fire on board, in Pernambouco. On October 26, 1920, she returned to Europe towed by the Gasconnier (4,186 miles to cover, ie 35 days at 5 knots). It was permanently canceled in 1922.

(Characteristics: 6400 t; 14000 hp; 114 x 15.7 x 7.9 m; Plans de Bussy; In steel; 20 Chaudières du Temple; 3 propellers; 480 h; II.194 + VI .164 + 12).

A deep sea submarine (1916 - 1935), laid down in Toulon on September 1, 1913 (Q105), she was floated on September 9, 1915, and entered service on July 22, 1916. She had a sister-ship, the Sané. On March 31, 1917, while he was part of the Moroccan naval division based in Gibraltar, he opened fire on an indigenous gathering at Wadi Arksis. In June of the same year, he was attacked by mistake and damaged by an English star in the middle of the strait. Redesigned in 1923 at the forges and shipyards of the Mediterranean at La Seyne-sur-Mer (despite protests from the DCAN which expected to have the market), it was soon after classified as a 1st class submarine (July 2, 1924). In March 1930, he joined Cherbourg to be put in a state of conservation, assigned to the 1st ESM. Sentenced on July 29, 1935, she was definitively removed from the fleet lists on August 27, 1935. Her hull was sold for demolition in Toulon on August 6, 1938.
