  Israel’s Rafael integrates artificial intelligence into Spice bombs

  By: Seth J. Frantzman and Kelsey D. Atherton Rafael Advanced Defense System's Spice bombs now have a new technological breakthrough as the Israeli company enables its Spice 250 with artificial intelligence alongside automatic target recognition to be used with scene-matching technology. The Spice 250, which can be deployed on quad racks under the wings of warplanes like the F-16, has a 75-kilogram warhead and a maximum range of 100 kilometers with its deployable wings. Its electro-optic scene-matching technology — which involves uploading terrain data onto the bomb and combining it with real-time electro-optic imagery — allows the weapon to work in GPS-denied environments. And the bomb can use this autonomous capability to navigate and correct its location, according to Gideon Weiss, Rafael's deputy general manager of marketing and business development at the company's air and C4I division. With its AI and “deep learning” technologies, the weapon has the ability to identity moving ground targets and distinguish them from other objects and terrain. This is based on 3D models uploaded to the bomb as well as algorithms. As the weapon identifies and homes in on its target, such as a convoy of vehicles, it separates the convoy of interest from other vehicles it has “learned” to ignore. “The deep-learning algorithm is indifferent to the actual data fed to it for modeling targets of interest and embedding their pertaining characteristics into the system," Weiss said. "However, the more the data used for modeling is representative of the target of interest, the more robust the recognition probability will be in real life.” Rafael has completed the development and testing phase of the Spice 250, including flight tests, which have “proven the robustness of the ATA and ATR, so it is mature for delivery,” Weiss said, using acronyms for automatic target acquisition and recognition. Asked if the ATR algorithm will select a secondary target if the computer cannot find the initial human-selected target, Weiss said: “This goes into the area of user-defined policies and rules of engagement, and it is up to the users to decide on how to apply the weapon, when and where to use it, and how to define target recognition probabilities and its eventuality.” Automatically selecting a secondary target may eventually become part of the upgrade profile for the munition, if customers express significant interest in the feature. With a two-way data link and a video-streaming capability, the bomb can be aborted or told to re-target up until a “few second before the weapon hits its target,” Weiss explained. That two-way data-link, enabled by the weapon's mounting on a Smart Quad Rack, or SQR, will enable future deep learning to be based on data extracted from earlier launches. Data recorded will include either live-streaming video or a burst of still images of the entire homing phase up until impact. “These are automatically and simultaneously recorded on the SQR — enabling two functions: (a) real-time and post-mission BDI (Bomb Damage Indication); (b) post-mission target data extraction for intel updates, etc.," Weiss said. "The ATR capability, including its deep learning updates, must be more agile than the enemy's ability to conceal and/or change its battlefield footprint, tactics, appearance or anything else which might impede the ATR from accurately recognizing and destroying targets.” The Spice family of weapons is operational with the Israeli Air Force and international customers. https://www.defensenews.com/artificial-intelligence/2019/06/17/israels-rafael-integrates-artificial-intelligence-into-spice-bombs/

  After Pacific tour, Navy’s No. 2 talks readiness, staying ahead of competition

  By CAITLIN DOORNBOS | STARS AND STRIPES YOKOSUKA NAVAL BASE, Japan — Vice Chief of Naval Operations Adm. Bill Moran heard right from the source how the Navy's largest foreign command is keeping up with readiness challenges, including a significant maintenance backlog and an ever-increasing competition landscape. Moran — the service's second-highest ranking officer — visited Navy bases in South Korea and Japan last week on a listening tour that he said brought helpful insight into on-the-ground operations in the Pacific. “We in Washington have our own views about things and it's largely programmatic in nature, budgetary in nature and some policy,” he told Stars and Stripes in an interview Thursday. “But to get feedback from sailors, commanding officers, chiefs and master chiefs in the fleet really helps us refine and make sure that we're supporting from Washington what they need [in the Pacific].” Readiness challenges At Yokosuka on Thursday, Moran spent time on the waterfront discussing ship maintenance. The base is home to U.S. Naval Ship Repair Facility Japan Regional Maintenance Center, which is working on what Moran called a “not insignificant” backlog. A request for exact numbers on that backlog went unanswered. The 7th Fleet is operating with fewer ships than it had planned after two of its guided-missile destroyers — the USS Fitzgerald and the USS John S. McCain — were severely damaged in separate fatal collisions at sea last year. While Yokosuka added an additional destroyer — the USS Milius — earlier this year, the fleet remains down two operational ships because Milius was originally intended to be an additional ship in support of Indo-Pacific operations, former Pacific Fleet commander Adm. Scott Swift told Stars and Stripes last year. Moran said the McCain, which is being repaired in Yokosuka, is expected to get out of drydock this fall and the Navy is aiming to have it underway in the spring. The Fitzgerald is undergoing maintenance in Pascagoula, Miss., and the service has said the goal is to return it to sea by 2020. Moran said ship maintenance “is a key critical element for overall fleet readiness.” “Everybody recognizes that we've got to do the maintenance that's built up over time. While that's important to everybody, no one likes to be in the yards,” Moran said. “There's a cost of doing that right now and we have to re-baseline the maintenance of our ships across the fleet, particularly [in the Pacific] because it is so active, it has been a very busy place for a long time.” On Sept. 12, Moran and Master Chief Petty Officer of the Navy Russell Smith toured Yokosuka's USS Blue Ridge, which has been undergoing maintenance for about two years. Crews first re-lit the boilers on the Navy's oldest commissioned operational ship in June, and Moran said the 7th Fleet's flagship is “about ready to go to sea.” “She's outfitted like an old ‘57 Chevy that we've took the engine out, took the dashboard out and put all modern capability in, and man, she sounds and she's going to run kind of nice,” Moran said. The Blue Ridge's staff moved back onto the ship this summer. Capt. Brett Crozier, the Blue Ridge's commander, said it was an honor to host Moran.
