WASHIGTON — Five former Maritime Administration officials have called on Congress to fund the construction of new sealift vessels instead of pushing the plan to buy and convert used ships on the open market.
In a letter to the chairs of the House and Senate Appropriations committees, officials from both Republican and Democrat administrations said replacing the nation's organic surge sealift fleet, which has an average hull life of 44 years, is essential to maintaining the ability to send troops and materiel overseas on short notice.
The letter, signed by former MARAD Administrator Clyde Hart, as well as four other former MARAD attorneys and policy chiefs, called for Congress to build new ships to spur shipbuilding in the United States and to cut down on maintenance hassles that could spell delays in a crisis.
“First, the new ships would be immediately operational,” the letter said, “and the Maritime Administration won't have to spend precious time finding long-obsolete parts, therein delay surge capacity. Second, building ships in the United States creates jobs, spurs spending and strengthens the U.S. shipbuilding industry.”
The letter comes in the wake of findings from last year's turbo activation that only about 40 percent of the sealift fleet would be ready to surge in a crisis, and that the force would be “challenged to be immediately ready for a large-scale inter-theater force deployment,” which is its entire raison d'etre.
The sealift fleet is composed of 26 Military Sealift Command pre-positioning ships, 46 ships in the Ready Reserve Force and 15 command-owned roll-on/roll-off surge force ships. Many of the roll-on/roll-off ships are steam-operated, and the obsolete equipment is causing significant personnel issues in the pool of qualified civilian mariners needed to operate them.
The White House's Office of Management and Budget favors a “buy used” policy for the sealift fleet, which is rapidly aging out.
The Army in 2018 sent a warning to the House Armed Services Committee in an information paper regarding the nation's surge sealift capacity — which would be responsible for transporting up to 90 percent of Army and Marine Corps equipment in the event of a major war. The Army said the capacity would fall below its requirement by 2024.
“Without proactive recapitalization of the Organic Surge Sealift Fleet, the Army will face unacceptable risk in force projection capability beginning in 2024,” the document said, adding that the advanced age of the current fleet adds further risk to the equation.
“By 2034, 70% of the organic fleet will be over 60 years old — well past its economic useful life; further degrading the Army's ability to deploy forces,” the document read.

Nine teams hailing from four continents gathered in Idaho Springs, Colorado, the week of April 5-11, 2019, to test autonomous air and ground systems for navigating the dark, dangerous, dirty, and unpredictable underground domain. The SubT Integration Exercise, known as STIX, took place at the Colorado School of Mines' Edgar Experimental Mine. The event provided a shakeout opportunity for competitors in advance of the Tunnel Circuit in August, the first of three subdomains that teams will tackle in DARPA's Subterranean Challenge. The teams were divided into three groups. Each group had one day to experiment with their various systems during multiple runs in the mine, followed by a second day in which each team attempted a one-hour mock, scored run. Teams could earn points by accurately locating, identifying, and reporting artifacts placed within the tunnels. Artifacts included thermal manikins, backpacks, fire extinguishers, cell phones, and cordless drills – all inspired by objects an end user such as a warfighter or first responder might encounter. The mine environment presented teams with low light, high dust, metal rails, and irregular terrain. The DARPA team added to the complexity with a theatrical smoke machine, which mimicked real smoke a warfighter or first responder could contend with in an emergency response scenario, for example. “It was amazing to see the progression from day one into day two for each team as they explored the tunnels of the mine and began to understand just how complex and unknown these underground environments can be,” said Timothy Chung, program manager for the Subterranean Challenge in DARPA's Tactical Technology Office. “It's not just about testing whether there's enough light or if robots can drive a few meters. It's about how all that has to come together in a difficult environment and the teams are experiencing the challenge of integration in addition to technology development.” The competitors at STIX included a mix of DARPA-funded and self-funded teams: CERBERUS University of Nevada, Reno ETH Zurich, Switzerland Sierra Nevada Corporation University of California, Berkeley Flyability, Switzerland CoStar: Collaborative SubTerranean Autonomous Resilient Robots Jet Propulsion Laboratory California Institute of Technology Massachusetts Institute of Technology KAIST, South Korea CRETISE: Collaborative Robot Exploration and Teaming In Subterranean Environments Endeavor Robotics Neya Systems CSIRO Data 61 Commonwealth Scientific and Industrial Research Organisation, Australia Emesent, Australia Georgia Institute of Technology CTU-CRAS Czech Technical University in Prague, Czech Republic Université Laval, Canada Explorer Carnegie Mellon University Oregon State University MARBLE: Multi-agent Autonomy with Radar-Based Localization for Exploration University of Colorado, Boulder University of Colorado, Denver Scientific Systems Company, Inc. PLUTO: Pennsylvania Laboratory for Underground Tunnel Operations University of Pennsylvania Exyn Technologies Ghost Robotics Robotika Robotika.cz, Czech Republic Czech University of Life Science, Czech Republic Following the Tunnel Circuit, teams will compete in the Urban Circuit, which will focus on underground urban environments such as mass transit and municipal infrastructure; and the Cave Circuit, which will focus on naturally occurring cave networks. Locations for the circuit events have not been announced. Qualification is ongoing for the circuit events. Requirements can be found in the SubT Qualification Guide available on the Resources Page. Teams interested in joining either the virtual or systems tracks can still register and are encouraged to join the SubT Community Forum to exchange ideas, explore teaming opportunities, and receive updates on the Challenge.

Par Nathalie Guibert De nombreuses applications de l'IA deviennent possibles gr'ce aux gigantesques quantités de données accumulées par les armées modernes, analyse la journaliste du « Monde » Nathalie Guibert. Analyse. Pour les armées modernes, « l'intelligence artificielle (IA) se présente comme la voie principale de la supériorité tactique » et elle est devenue « un enjeu de défense prioritaire pour les puissances militaires du XXIe siècle ». Dans une étude que publie l'Institut français des relations internationales (IFRI) sur cette nouvelle révolution, un ancien pilote de l'armée de l'air, Jean-Christophe Noël, évoque un « humanisme militaire » menacé. Il n'est pas certain, selon lui, que les robots pourront toujours, en accord avec le « modèle de l'équipier fidèle », rester « étroitement associé(s) à un homme en charge d'un système d'armes comme un avion de chasse, un blindé ou un navire ». Les applications militaires de l'IA deviennent accessibles et semblent sans limites. Elles sont rendues possibles par les gigantesques quantités de données (images, sons, etc.) désormais accumulées – un Rafale produit plusieurs téraoctets de données par heure de vol, et chacun des trois satellites d'observation français successeurs d'Helios 2 permettra de produire, à partir de 2019, cent fois plus d'informations que l'ensemble de ceux utilisés aujourd'hui par les armées. De plus, les algorithmes acquièrent la capacité nouvelle d'apprendre seuls selon les situations qu'ils rencontrent. Préparation au combat par la simulation, renseignement, ciblage, optimisation du soldat... La course a démarré. « Hyperwar » Le département de la défense américain a lancé près de 600 projets intégrant l'IA, un domaine où il vient d'annoncer 2 milliards de dollars (1,7 milliard d'euros) d'investissement dans les cinq prochaines années. « Une IA surnommée ALPHA, qui fit ses classes en affrontant des programmes informatiques de combats aériens de l'Air Force Research Lab, a systématiquement triomphé d'un pilote de chasse chevronné en octobre 2015 »,rappelle l'expert de l'IFRI.
