Unmanned systems, anti-drone tech featured at South Korean arms expo

By:

SEOUL — Unmanned defense systems and advanced weapons to counter drone threats dominated an arms exhibition held outside of Seoul, South Korea, this week.

During the biennial DX Korea event, which ran Nov. 18-20, local defense companies showcased their cutting-edge unmanned and counter-drone technologies.

Hanwha Corporation, a leading developer of guided-missile technology and subsidiary of Hanwha Group, displayed its new family of laser weapons systems. The company unveiled two types of anti-drone laser weapons: one for installation on light tactical vehicles, and the other a laser-based anti-aircraft weapon gun in a container configuration. The latter, designated as Block I, can be modified to a Block II self-propelled system, but specifications were not disclosed.

Hanwha Corporation is a partner in an anti-drone laser weapons development project led by the government's Agency for Defense Development.

“The laser-based anti-aircraft weapon is a new concept of armament to shoot down small aerial targets, including drones and multi-copter with a light source laser,” the company said in a news release. “Prototypes of the laser weapon variants are under development jointly with the ADD.”

The company also displayed anti-jamming equipment that can be fitted in tactical guided missiles as well as on military vehicles and naval vessels.

Hanwha Systems — also an affiliate of Hanwha Group — displayed a mock-up of its personal air vehicle, Butterfly, under development with U.S. air taxi startup Overair. In partnership with Overair, Hanwha Systems plans to fully develop the electric vertical-takeoff-and-landing, or eVTOL, vehicle by 2040, with an eye toward military sales.

“With technologies to be accrued from the development of commercial eVTOL, we will push for developing a military variant capable of conducing multiple missions, including special operations, transport and assault,” the company said in a news release.

Meanwhile, Hyundai Rotem presented its HR-Sherpa unmanned ground vehicle designed to support infantry troops.

The six-wheel drive vehicle can move autonomously or via remote control to perform missions such as surveillance, medical support and chemical detection. It has a payload of 600 kilograms and a combat weight of 1,800 kilograms. It is equipped with airless tires and powered by a battery with an operating time of six hours when traveling at 5 kph.

LIG Nex1 showcased the third version of its Sea Sword unmanned surface vessel for riverside defense, following other naval variants.

The vessel adopts a high-speed monohull design and is constructed with fiber-reinforced plastic. Equipped with a diesel engine and a waterjet propulsion system, the boat can sail at a maximum speed of 40 knots and has an operational endurance of up to eight hours at 15 knots.

An indigenously developed autonomous navigation system enables the vessel to carry out surveillance and reconnaissance missions based on a preprogrammed route.

Hanwha group was ranked 32nd in Defense News' list of the top 100 defense companies in the world. LIG Nex1 was ranked 68th, while Hyundai Rotem was ranked 95th.

    Opportunity knocks: A look at the used helicopter market

    by Howard Slutsken If you're thinking of buying or selling a used helicopter, this might actually be a good time to do so. Maybe we're finally getting past our focus on the doldrums in the oil and gas sector, or it could be that the replacement cycle is catching up with older helicopters, with operators making the decision to upgrade their fleets. The helicopter market has always been very cyclical, and the perceived strength of the marketplace will often depend on the specific needs of a region — and the opinion of who you talk to. “The trend we're seeing in Canada is for hydroelectric powerline work, whether patrol or working on the towers, they're going with Cat A twin-engine aircraft,” said Steve Dettwiler, president of Maple Leaf Helicopters Canada, a brokerage service based in British Columbia. “Some operators are using the MD 902 Explorer, others the [Airbus] EC135. There are lots of [Airbus AS350] AStars available, but for Cat A [performance requirements], you'd have to go with an [Airbus] AS355NP TwinStar. “We're seeing the Bell LongRangers being sold off and replaced by the AS350 B2 and B3 series,” Dettwiler continued. “When it comes to the B3e [H125], most Canadian operators are interested in the ones that have dual hydraulics. For forest service work, there's the inclination to go to twin-engine on the Bell mediums.” Airbus machines are certainly in demand, and it might be a better financial and operational decision to search the used market rather than buy new, according to Jason Kmiecik, president of HeliValue$, producers of The Official Helicopter Blue Book. “The lights twins — EC135s, 145s — there's a big market for those,” he said. “In the U.S., Metro Aviation and Air Methods have pretty much grabbed everything [in terms of those types] that was for sale or is about to come online for sale. In today's market, you could buy two used aircraft, fully retrofit them with brand new interiors and avionics in both aircraft, and you're at about the price of one brand new aircraft. “There are plenty of transactions happening on those aircraft all over the place,” Kmiecik continued. “Some of them have actually started going up in value — the AStars and some of the newer 407s — because there's just starting to not be that many out there for sale.” Finding a deal But, as with any marketplace, there are bargains to be found. “There are some really good deals out there,” said Dettwiler. “As an example, we've got a Bell 212 for sale for $1.5 million, which is a good price for a 212. [The market] does go in cycles. Right now there are a lot of aircraft available for sale, which drives the prices down. You can get into a nice little JetRanger probably for $350,000 to $400,000.” There's also a bit of an underground marketplace where transactions happen quietly, with a handshake, explains Kmiecik. “You'll see the sales happen,” he said. “They were never listed online. They sell to the operator next door or somebody's buddy. The smaller, cheaper aircraft are garage transactions.” And speaking of those smaller machines, Kmiecik believes that the operators who still love Schweizer helicopters are going to be happy with the company's new owners, Schweizer RSG. “Their plans are to go full production again,” he said. “So I think there's going to be a comeback of Schweizer.” While Kevin Mawhinney, helicopter technical advisor at Jet Support Services, Inc. (JSSI), doesn't think much has changed in “the day-to-day, ins-and-outs of the industry,” he does see a trend developing in the “larger-medium” sector. “I think you're going to see more people move into this segment with machines that fill that niche,” he said. “For example, the [Leonardo] AW139 has really filled a need, and we're seeing a lot of interest in it.” He points to the multi-role capability of the AW139 as being a driver for new operators. “I think it fills a niche that no other machine was filling before.” Super Pumas airborne again And what about all of those Airbus H225 Super Pumas that have been languishing on helipads around the world? They're now in demand, according to Kmiecik — but for utility work, not offshore. “What we're seeing now is supply is actually shrinking,” he said. “Aircraft that were once for sale are now pulled off the market and are back to work with the original lessees or new people.” With the shift in deployment of Super Pumas from offshore work to utility missions, Kmiecik said that there's a bottleneck getting the parts that operators need to change the primary mission of their helicopters. “The 225 is becoming the utility machine, the go-to machine now,” he said. “The problem is the supply of utility parts with Airbus — cargo hooks and stuff like that. They can't get them in stock fast enough to ship out to the people who need them. There's aircraft waiting on the ground right now for parts so they can get out on a contract.” Kmiecik said that some operators have recognized the value in the 225 and have focused their acquisition strategy on the type. “It's a lot of aircraft with a lot of lifting for the price.” Dettwiler also knows of companies that targeted an opportunity by buying up inventory of specific types. “We sold 14 SA 315B Lamas in the past few years to a company in Scandinavia, who's basically stockpiling all the Lama inventory from around the world and supporting the existing Lama operators. But it's going to come to an end. Airbus would prefer to sell the H125/AS350 B3e,” he said. Operating costs Brandon Battles, vice-president, Conklin & de Decker, has been researching and analyzing helicopter operating costs for over 30 years. With his years of experience, Battles has seen the cyclical changes that the industry has faced. “I think we've all seen it through our careers - oil and gas is bad right now, but another operation that uses helicopters might be very strong,” he said. “The firefighting folks are probably having some pretty good years, from a business point of view. “I'm noticing now that it's not just the acquisition cost that's important anymore, it's also those operational costs that they'll be encountering over the long ownership of that aircraft,” he added. Kmiecik echoes that thought. “Pretty much everybody's complaint is to try to get operational costs cheaper for these aircraft, especially for the S-92,” he said. “It's a very expensive aircraft to operate, and with what they're making each month on their contracts, it's getting very tight to be able to make a profit at all on them.” While some of the focus on operational costs may be driven by corporate acquisitions and industry consolidation, Battles believes that operators at all levels have become more attuned to the business side of the equation, in some ways resulting from the economic downturn of 2008. He said that operators may have planned to acquire a helicopter and keep it for perhaps 10 years. After that, they may look to sell it to avoid major inspections or the required replacement of life-limited items or other significant maintenance. “They had a plan but when the economy changes and they can't sell the aircraft for as much as they planned, now they must continue to operate it and wrestle with some of the higher costs that are associated with an older aircraft,” said Battles. “Maybe because of that experience, people are considering the maintenance and operating costs more than they used to.” What's next? Kmiecik's analysis of the super-medium market suggests that machines like the Airbus H175, Leonardo AW189 and the upcoming Bell 525 are going to face challenges in making an impact on the market. “In general, the super-mediums haven't lived up to expectations that everybody thought was going to happen,” he explained. “And that's because the S-92 has dropped in value, so where it's actually cheaper to rent a S-92 than it is to buy a brand new super medium. “Capital is drying up in the space,” Kmiecik continued. “There's not many people that are willing to go out and buy a $15- to $35-million helicopter anymore for offshore when we've got so much supply still in the market right now that is sitting idle for sale.” And Kmiecik is pretty blunt in his assessment of what needs to happen in the oil sector to ensure that helicopter operators can continue to provide service. “I think over the next six months to a year, you're probably going to see some change in the attitude of the oil companies,” he said. “There has to be a change because they're forcing everybody into bankruptcy. I think that people are now telling them ‘no' on certain requirements that they're setting on tenders, like age requirements for aircraft. I think that they're going to have no choice but to start helping out the people who are keeping them in business.” https://www.skiesmag.com/features/opportunity-knocks-a-look-at-the-used-aircraft-market

    Air Force gets new stopgap system for GPS 3 satellites

    By: Nathan Strout The U.S. Air Force's first next-generation GPS satellite launched in December and the second GPS III satellite is slated to liftoff in July. But there Air Force has a problem: The ground system currently in use isn't fully capable of controlling GPS III satellites. Worse, a new ground system that can, formally known as the next-generation operational control system (OCX), is five years behind schedule and won't be delivered until June 2021 at the earliest, according to the Government Accountability Office. Enter the GPS III Contingency Operations (COps) software—a critical stop gap measure that will update the current ground control system and allow it to access some of the more advanced features of the GPS III satellites until the next-generation operational control system is ready. On July 11, primary contractor Lockheed Martin announced that it had delivered the COps upgrade to the Air Force. “Positioning, navigation and timing is a critical mission for our nation and COps will allow the Air Force to gain early access to its new GPS III satellites,” said Johnathon Caldwell, Lockheed Martin's vice president for Navigation Systems. “We just finished final qualification testing and delivery on COps, and it will be integrated and installed on the [Architecture Evolution Plan Operational Control System] over the summer. We look forward to the Air Force ‘flying' a GPS constellation on the COps OCS which includes the new GPS III satellites, later this year.” The new GPS III satellites are built to be more robust and accurate than their predecessors and come with advanced features such as the ability to use M-Code, an encrypted GPS signal for use by the military. The COps upgrade will allow the current ground system to control the GPS III satellites as well as the legacy GPS satellites. It will also allow the current system to access M-code Early Use, an encrypted GPS signal with improved anti-jamming and anti-spoofing capabilities, beginning in 2020. The Air Force contracted with Lockheed Martin to deliver the patch in 2016, the same year that the OCX program triggered a Nunn-McCurdy cost breach—a type of violation caused by significant cost growth that requires a program to be shut down unless the Department of Defense intervenes and approves a new cost estimate. The $6.2 billion OCX program is already five years behind schedule, and a May 21 Government Accountability Office report warned that the OCX program could be delayed even further. In addition, the Air Force has acknowledged that delays are possible during the seven-month testing period following delivery. Raytheon, the primary contractor behind OCX, rejected the GAO report, claiming that its findings were inaccurate. https://www.c4isrnet.com/battlefield-tech/c2-comms/2019/06/11/air-force-gets-new-stopgap-system-for-gps-3-satellites/
