Elta Systems, Hensoldt partner on system to consolidate submarine capabilities
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.”

Are the days of pulling pits at the rifle range coming to an end?
By: Shawn Snow As a shooter on rifle range qualification day, have you ever seen your target come up crooked, barely hanging onto the stand, and wonder, “What the heck are the Marines doing in the rifle pits?” Pulling pits at the rifle range might be most Marines' least favorite task. It requires constantly raising and lowering targets just to see them fall off the rickety stands, and quickly patching them up with pasties to give the shooter a clean canvas ... just to watch them fall off again. It's a frustrating, tedious task. There's the fact you have to rely on another Marine in the pit to accurately score your shots — and that one-point difference between the marksmen pizza box badge and sharpshooter can save a a lot of scorn before the next chance to qualify. There's the shooter who probably missed the target entirely during the last course of fire, leaving the scorer staring at the target for an eternity, seeking a nonexistent shot hole. There's always the Marine who shoots on the wrong target — those must just be bonus points to help a buddy who is about to fail on the range. The Corps' entire rifle range qualification process is rife with human error and inefficiencies that can impact Marines' scores on the range. Well, the Corps finally is looking to remedy this. In a request for information posted on the government's business opportunities portal, the Corps is in the hunt for an automatic scoring system for its ranges. In the posting the Corps said that the purpose of the new scoring system is to “reduce the amount of labor necessary to conduct KD [known distance] training/qualification. By eliminating the need for target operators in the pits, the labor overhead associated with KD training is greatly reduced.” “During marksmanship training the KDAS [known distance automated scoring] will be required to accurately show the shooter where they hit the target, to provide feedback that will assist the shooter in developing their shooting skills," the RFI stated. And the Corps is looking for a complete system that will streamline the scoring process and ease the rifle range qualification process. According to the RFI, the Corps wants new scoring platform display systems for coaches and shooters. For marksman coaches on the range, a new display unit will allow the coach to view and track the shots of four shooter lanes at once. Shooters will have a display unit that will let them track their individual shot placement and score as well. A single control system will be able to communicate wirelessly and control up to 100 targets at once, according to the RFI. That means no more Marines in the pits manually pulling targets up and down. The new scoring system is intended to reduce “the amount of time shooters need to spend on the range, freeing them up to perform other work,” the RFI reads. So maybe the days of showing up to the range at dawn also are coming to an end? Responses to the Corps' request for information regarding the new scoring system are due by Jan 11. https://www.marinecorpstimes.com/news/your-marine-corps/2018/12/18/are-the-days-of-pulling-pits-at-the-rifle-range-coming-to-an-end
