The project management will lie with <a href=\"https:\/\/www.defensenews.com\/smr\/euronaval\/2020\/10\/22\/naval-group-will-repair-french-perle-nuclear-sub-damaged-by-fire\/\" target=_blank>Naval Group<\/a> and TechnicAtome, the latter being the prime contractor for the nuclear boiler room.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Thales announced it signed a memorandum of understanding with the DGA for the development of a complete sonar suite for the boats \u201cbased on disruptive technologies that represent a significant break from the systems in service today.\u201d The company will provide new-generation flank arrays and bow-mounted sonars; a towed linear array based on optical technology; as well as intercept arrays, echo sounder technology and underwater telephones. The company said the new sonar suite will be incrementally deployed, with the first versions installed on the current SNLEs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Parly said the new submarines will be \u201cslightly longer and heavier\u201d than the current Le Triomphant class, which first sailed in 1995 and will continue to do so until 2050. She added that the vessels will \u201chear better and defend themselves better whilst at the same time being more silent: They will not make more noise than a school of shrimp.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Parly noted that given the extreme length of this program, France will \u201cmaintain a margin for evolutions [in the design], indispensable to take account of technological breakthroughs that we cannot forecast today \u2014 I\u2019m thinking notably of cyber defense, improvements in acoustic stealth and the development of better-performing sensors.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Parly announced the launch of the program at the DGA\u2019s hydrodynamic technologies center at Val-de-Reuil where all the French Navy\u2019s submarines have been designed and evaluated over the past 60 years, and where work on this third generation of SNLEs has already been underway for more than a decade.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cFifteen million hours have already been spent on development studies, and a further 20 million will be necessary for each submarine,\u201d she said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">She partly credited the program existence with the hydrodynamic technologies center\u2019s 2017 acquisition of computer technology know-how.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The minister also noted that in a few weeks the DGA will celebrate its 60th anniversary. \u201cThe world has undergone deep changes since 1961,\u201d she said, \u201cbut if the ways of making war are no longer the same, those of keeping the peace remain. As the president confirmed [in February 2020], nuclear deterrence is and remains the keystone of our security and the guarantee of our vital interests.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">She noted that 2021 also marks the 50th anniversary of the permanent patrols of France\u2019s nuclear-powered ballistic missile submarines, a mission she likened to \u201ca rocket launch pad, a real underwater Kourou [the space base in French Guiana] with 16 rockets ready to go, all integrated into a combat submarine propelled by a nuclear power station.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What&#8217;s quieter than a school of shrimp?
