A603 Henri Poincaré
A 603 Henri Poincaré is a former Italian oil tanker redesigned building to become a Bâtiment d'Essais et de Mesures [ BEM - Test and Mesurements Ship]. The vessel received special facilities and was equipped with special equipment, when these alterations in BREST 2. (detection, transmission, telemetry, computing, weather).
Jules Henri Poincaré (1854—1912) was an influential French philosopher of science and mathematics, as well as a distinguished scientist and mathematician. In the foundations of mathematics he argued for conventionalism, against formalism, against logicism, and against Cantor’s treating his new infinite sets as being independent of human thinking. Poincaré stressed the essential role of intuition in a proper constructive foundation for mathematics. He believed that logic was a system of analytic truths, whereas arithmetic was synthetic and a priori, in Kant‘s sense of these terms. Mathematicians can use the methods of logic to check a proof, but they must use intuition to create a proof, he believed. He maintained that non-Euclidean geometries are just as legitimate as Euclidean geometry, because all geometries are conventions or “disguised” definitions.
Henri Poincaré was the only ship of this class and, until its disabling in the 1990s, was the flagship of Formation M, the French Navy's test and measurement group, which carried out various measurements and experiments in the interests of the Navy and other organizations like the military. and civilians. Its main task was to track the flight of sea and land-based ballistic missiles launched from launchers at the Landes test site or SSBN mines, as well as measure the parameters of their trajectory and other characteristics, especially at the final section and at the point of impact. When carrying out such launches, Poincaré also performed the functions of a control and safety ship, controlling the air and surface space in the test area, in particular in the zones of the fall and rise of warheads.
Poincaré was built as an Italian tanker and reconstructed in 1954-1967 to meet these challenges. In the 1979-1980s, a serious modernization of its radio-electronic equipment was carried out, which includes the Savoy and Gascoigne tracking radars, an automatic tracking station, astronomical navigation equipment, a cine-theodolite, infrared tracking systems, the Transit navigation system, satellite Syracuse communications system, meteorological and oceanographic equipment, data collection and processing system, and a subkeeping GAS. A helipad and a hangar for two SA 321 Super Frelon heavy transport helicopters or five Aluette-3 general-purpose light helicopters were equipped to resupply at sea and transport personnel.
It was put up for auction on October 7, 1992, being after the PA the 3rd largest vessel in the fleet, it (already) represented a good quantity of precious metals to be recovered: 23,590 Tons after recovery by the Navy of all that could still to serve. There were many buyers for sale, the biggest having bid in writing being a Greek, a Spaniard, a German, two Dutch, an English and Michel Guyot from Brest recovery. The auction started at 220 0000 F and rose very quickly, the Brestois let go after the proposal of an Englishman at 515 0000 F but in the end it was the Dutch Albert Dalmayer of the Damet marine company who won for a total price of 561 6000 F (all taxes included lol!). He sold it himself with a large profit thereafter to go for demolition.
At present, the "Poincaré" functions are performed by the "Monge" measuring complex ship, built in 1992.
