Le gouvernement a annoncé le 3 novembre le lancement de la réalisation du système de lutte anti-mines futur (ou SLAM-F). Thales a déjà construit un prototype dans le cadre de ce programme d'armement innovant.

Le système de lutte anti-mines futur (ou SLAM-F) se précise. Mardi 3 novembre, le gouvernement a officialisé “le lancement en réalisation” du programme d'armement. Dès 2022, la Marine nationale s'équipera de drones sous-marins et de surface pour affronter la guerre des mines.

À quoi va servir le SLAM-F ?

“Le SLAM-F remplacera à terme tous les moyens actuels de guerre des mines (chasseurs de mines tripartites, b'timents remorqueurs de sonars, b'timents bases de plongeurs démineurs)”, rappelle le ministère des Armées dans un communiqué. Concrètement, il permettra aux forces françaises de neutraliser des mines à distance à l'aide de drones, afin de ne plus exposer des plongeurs ou des marins.

“Ce système nous permettra de détecter des objets de la taille d'une carte bleue – c'est 30 fois plus petit qu'avec nos moyens actuels. Notre capacité de détection et de neutralisation ira jusqu'à 300 mètres de fond, contre seulement une centaine de mètres avec nos moyens actuels", détaillait la ministre des Armées, Florence Parly, lors d'un discours en mai.

Les drones démineurs du programme auront notamment pour mission d'assurer la sécurité d'unités stratégiques de l'armée française : celle des sous-marins nucléaires lanceurs d'engins (SNLE), piliers de la dissuasion nucléaire, ou encore celle du porte-avions Charles de Gaulle. Le ministère des Armées mentionne aussi des usages pour protéger l'accès aux ports français, soutenir le déploiement d'une force d'action navale, sécuriser l'évacuation de ressortissants français ou participer à la prévention de crises.

Un programme d'armement à plusieurs étages

Comme le système de combat aérien du futur (SCAF), le SLAM-F comportera plusieurs volets. Au coeur de cette architecture, on retrouve des systèmes de drones capables d'être opérés depuis la terre ferme ou depuis un navire militaire dédié. La France et le Royaume-Uni collaborent depuis 2012 sur ce volet baptisé MMCM (pour “Maritime mines counter measures”).

En 2015, le groupe français de défense Thales avait été désigné chef de fil industriel de ce volet. “L'étude de définition et la réalisation des prototypes du système de drones ont été confiés à Thales, dont la société Études et constructions aéronautiques [ECA, filiale du groupe Gorgé] sera le principal sous-traitant français”, confirme le ministère des Armées dans son communiqué.

Thales avait déjà testé un chasseur de mines ultra-moderne en 2019 en collaboration avec la Marine nationale. Le groupe français fait figure de champion dans ce domaine. "Plus de 30 marines dans le monde sont équipées de sonars de guerre des mines Thales", soulignait Florence Parly en mai.

Des livraisons prévues jusqu'en 2030

Le SLAM-F contient trois autres volets : des b'timents de guerre des mines (BGDM) dédiés à la conduite et à la mise en oeuvre des drones, des b'timents bases de plongeurs démineurs nouvelle génération (BBPD NG) et enfin un système d'exploitation des données de guerre des mines (SEDGM).

Dans son communiqué, le ministère ne nomme pas d'autres entreprises participant à ce projet. “L'organisation industrielle de SLAM-F sera progressivement définie lors de l'attribution des marchés afférents aux différents volets du programme”, indique simplement le gouvernement.

Le calendrier du SLAM-F prévoit la livraison de huit systèmes de drones anti-mines à partir de 2022. À l'horizon 2030, quatre à six BGDM devraient compléter les flottes françaises avec cinq BBPD NG.

    Federal contractors face great uncertainty as coronavirus spreads

    Andrew Eversden To stop the spread of the new coronavirus, federal agencies could shutter facilities. States and localities are already issuing shelter-in-place orders. And with obscure rules surrounding telework for federal contractors as well as the potential for supply chain disruptions and employee infections, there could be a new level of unpredictability for the contractor community. “There's both a little bit of stability and a fair amount of uncertainty,” said Alan Chvotkin, executive vice president and counsel at the Professional Services Council, an interest group representing more than 400 government contractors. “Things that were normal yesterday are not normal today. Behaviors that were planned for over the last couple days have been changed as government missions are changing,” he added. In the near term, schedules laid out in contracts will likely experience delays and costs may increase due to disruptions caused by COVID-19, said Jonathan Aronie, head of law firm Sheppard Mullin's government contracts practice group. These disruptions could be caused by employees not coming into work, or their suppliers' employees not working. President Donald Trump said March 18 that he's willing to use the Defense Production Act to force companies to manufacture goods the government needs to fight the virus, like ventilators or masks. These orders become “rated,” essentially allowing the government to skip to the front of the line. That poses other challenges. “While some companies are going to have problems that are slowing them down, other companies are going to have the problems associated with an influx of new orders,” Aronie said. Aronie warned of a complex web of orders that companies could have to fulfill, pulling businesses in different directions. For example, he said, companies could get an order from a hospital, an order from a state government with a preexisting contract, and then a rated order from the federal government as well as agencies without rated authorities — potentially overwhelming and confusing manufacturers. “Somehow you're going to have to make sense of this all,” Aronie said. Effects of telework Across the government, federal employees eligible for telework have generally been allowed to do so. But contractors haven't always followed the same rules. Not allowing contractors to telework could have significant ramifications, experts warned. Many contractors are required by their contracts to work in government facilities. But to stop the spread of COVID-19, access to these facilities could be limited or completely shut off. This conundrum leaves contractors with questions for the government. “Are there going to be access issues? Are contractors going to be asked in some cases to work from home where previously they were going into a government facility? What does that mean from a performance perspective? What does that mean from a cost perspective? How do you work that out with the government?” said Roger Waldron, president of the Coalition for Government Procurement. “These are some of the thing people are thinking about.” On March 20, the Office of Management and Budget's deputy director for management, Margaret Weichert, released a memo urging agencies to “maximize telework for contractor employees.” But, as reported by Federal News Network, Weichert's memo did not mandate telework for federal contractors, leaving industry frustrated. Several interest groups that represent government contractors called on congressional leaders and the White House to allow contractors to work from home. PSC wrote a letter to OMB on March 18 warning that not issuing guidance regarding extending telework flexibility to contractors could lead to layoffs. “The duration of this is a huge uncertainty, if it does get worse before it gets better, if folks are really unable to perform the kind of work that need to be done at some government locations, that'll have some impact on people,” Chvotkin told Federal Times. Over the last few days, several states such as California and New York have begun following shutdown orders that could leave contractors in tenuous positions. A Justice Department memo from March 20 also directed U.S. attorneys general to tell state and local officials that federal employees must be allowed to travel and commute, “even when travel restrictions are in place.” This action didn't mention contractors either. State governments are going to have to “recognize that exceptions are going to be essential and some federal missions are just going to be so important to continue on that they'll have to accommodate them,” Chvotkin said. How does this compare to the government shutdown? This is the second consecutive year that contractors have faced challenges due to a crisis; last year's was the record 35-day government shutdown. Some aspects of the 2019 shutdown and the coronavirus crisis are the same. For example, Aronie said, both increase delays and incur higher costs on contractors. The big difference is that some companies will receive more work, instead of less. Another significant difference is that employees, both from the federal government and contractors, are still working — many federal employees from home. This increase in telework has increased agencies' demands for IT infrastructure as they work to accommodate the rise in telework. Last week, the White House requested several billion dollars for agencies to improve their IT infrastructure. Under the COVID-19 pandemic, the uncertainty is greater than during a government shutdown, experts said, because the ending was solely in the hands of the government. “Even in the shutdown ... everybody recognized that it was going to end sooner or later. It was under both the congressional and presidential control to bring an end to it — not so here,” Chvotkin said. “There's nobody who can just decree that the coronavirus has been cured.” https://www.federaltimes.com/govcon/contracting/2020/03/24/federal-contractors-face-great-uncertainty-as-coronavirus-spreads
