    Elta Systems, Hensoldt partner on system to consolidate submarine capabilities

    Seth J. Frantzman JERUSALEM — Israeli company Elta Systems has partnered with German firm Hensoldt to develop a single piece of technology for submarine masts that combines optics, communications and other sensors. The Integrated Communication and Surveillance, or ICS, system combines Hensoldt's optical surveillance optronics mast OMS 150 with Elta's expertise in signals intelligence and satellite communications payloads. Elta, a subsidiary of Israel Aerospace Industries, said the product will address the need to combine operational possibilities on one mast while maintaining the submarine's stealth capability. “The collaboration is part of Elta's new strategy, leveraging our advanced technological experience and know-how accumulated over decades of defense operations. This collaboration will bring value to our customers by offering a unique, cost-effective, compact and high-utility solution,” Elta CEO Yoav Tourgeman said. The ICS system combines optics, radar warning, and monitoring of GPS and communications with other vessels and units. “The data gathered in real time can provide the submarine's crew vital information regarding the enemy's exact location and current situation. It is equipped with a SATCOM and Laser system for secure communications,” according to an Elta statement. The system is being rolled out as part of the European maritime trade show Euronaval, which is being held virtually this year due to the coronavirus pandemic. Brent Sadler, a senior fellow for naval warfare and advanced technology at the Heritage Foundation think tank, said submarine forces are likely to grow in the coming years, which means "the market for periscopes is growing faster than in the recent past.” “So the trend is to reduce the number of masts you stick out of the water,” he added, "so if you have a periscope and need to do radio communications or listen for hostile radar, better to have that on one mast.” According to two sources involved with developing the ICS system at Elta, the new integration seeks to provide submariners with additional capabilities that complement a naval task force. The demand for submarines is increasing, and as they performing less missions strictly alone, the subsurface boats need more sensors and communications tools to work with other vessels as well as airborne and ground assets. Sadler points out that one of the challenges here is not only miniaturizing add-on payloads but also cooling the thermals because these additions and sensors add heat that can be detected. The traditional dilemma for submariners is performing missions successfully while reamining stealthy, according to Elta naval systems expert and retired Israeli Navy commander Shlomi Dor. “You need a communication mast, and adding an ISR capability with SATCOM on the same periscope — it's the only mast that keeps safety for submarine[s] ... and communicate[s] to task force and headquarters, whoever you need to be in touch with. This mast is a very robust solution that I think will contribute a lot for mission's sake all over the world.” The integration of the ICS system on the mast can be done in a refit without changes to existing submarine infrastructure, according to Elta. Michael Sela of Elta told Defense News that the system builds on mature and field-proven sensors, and uses the company's expertise in phased array SATCOM antennas and other technology. It is expected to be operational in the near future. Developments in periscope design, among other technological trends, will impact submarine designs, perhaps making them smaller with taller periscopes, Sadler said. An uptick in submarine purchases means increasing economies of scale that lead to the research and development behind new designs. But Sadler raised concerns about Elta's parent company, IAI, cooperating with China on civil aviation projects. The West, in particular the United States, has raised the alarm over China's involvement in the defense industrial base. That is also true for potential customers in Asia and Europe, where partnerships with China are being questioned more, he said. “The capability has a niche and fills market demand, [but] make sure that the China connection [is] addressed.” https://www.c4isrnet.com/industry/techwatch/2020/10/21/elta-systems-hensoldt-partner-on-system-to-consolidate-submarine-capabilities/

    Air Force looks to use fleet’s largest cargo plane for medical evacuations

    By WYATT OLSON | STARS AND STRIPES The Air Force is moving ahead to certify the cargo hold of its largest plane, the C-5M Super Galaxy, for use in medical evacuations for both casualties of war and victims of natural disasters. Nearly as long as a football field, the Super Galaxy has significantly more capacity than the C-17, the largest aircraft used by the Air Force for aeromedical evacuations in the cargo area. The Super Galaxy is certified for such evacuations using its passenger area, not its cargo hold. This month, the Air Force completed a two-year initiative to prepare, equip and test the Super Galaxy for the broader certification. Its cargo floor can accommodate 89 unstacked litters, twice as many as the C-17, which can fit 48 unstacked litters, according to a statement provided to Stars and Stripes by the Air Mobility Command. A C-130 can move only 15 patients on its cargo floor. A final proof-of-concept test for the Super Galaxy was recently successfully completed at Scott Air Force Base, Ill., and certification to support aeromedical evacuations could come as early as this summer. About 100 personnel were involved in the culminating test, with the C-5M and crew flying in from Travis Air Force Base, Calif. For the purposes of certification, the Super Galaxy was configured with a proprietary litter-stacking system that reduces the maximum number of stretchers its bare cargo area could hold. Under this configuration, the Super Galaxy “can safely move 244 ambulatory patients and has space for 40 litters,” Air Mobility Command said. The aeromedical evacuation squadron brought aboard its standard in-flight kits used for medical care, and a transportable galley and lavatory were also added. The Super Galaxy can carry a payload of nearly 135 tons, with enough cargo space to carry, say, two tanks, 16 Humvees and three Black Hawk helicopters. Without cargo, it has a range of 7,000 miles without the need for refueling. The Super Galaxy is an upgraded version of the legacy C-5, which was introduced in the 1960s. Its more powerful engines provide more thrust, shorter takeoffs and longer range.
