L3Harris to build prototype satellite capable of tracking hypersonic weapons

WASHINGTON — The Missile Defense Agency awarded L3Harris Technologies a $121 million contract to build a prototype satellite capable of tracking hypersonic weapons, the agency announced Jan. 14.

Under the contract, L3Harris is tasked with building an on-orbit prototype demonstration for the agency's Hypersonic and Ballistic Tracking Space Sensor, a proliferated constellation in low Earth orbit that is capable of detecting and tracking hypersonic weapons.

The constellation is designed to fill the gap in the country's missile defense architecture created by hypersonic weapons, which are dimmer than traditional ballistic missiles, making them harder to see with the nation's infrared sensors based in geosynchronous orbit. In addition, they are able to maneuver around terrestrial sensors. With China and Russia developing these weapons, the Department of Defense is eager to develop a new constellation that can detect and track the threats anywhere in the world. And so is Congress — in December lawmakers set aside $130 million to fund the project.

The HBTSS design solves the hypersonic weapon problem by placing the sensor much closer to the Earth's surface in the lower orbit, making it easier to see the threat. But because the sensors are closer to the Earth, they have a far more limited field of view than the sensors in geosynchronous orbit. In order to achieve global coverage, the Missile Defense Agency wants a proliferated constellation made up of dozens of satellites on orbit.

L3Harris was one of four companies awarded $20 million contracts in 2019 to develop a prototype payload design and risk reduction demonstration for HBTSS, along with Northrop Grumman, Leidos and Raytheon Technologies. According to the initial contract announcements, work on those designs was due Oct. 31, 2020. With this most recent award, L3Harris has won the subsequent competition between the four companies to build the actual prototype.

The company has also been selected to build satellites for the Space Development Agency that will track hypersonic threats and feed data to HBTSS.

In October, L3Harris won a $193 million contract to build four of the agency's eight wide field of view (WFOV) satellites, with SpaceX building four more.

According to Space Development Agency leaders, their satellites will work in conjunction with HBTSS satellites to track hypersonic threats. The WFOV satellites will provide initial detection and tracing of the weapons, passing custody from satellite to satellite as the threats traverse the globe. Then, the WFOV satellites will pass custody to the medium field of view HBTSS satellites, which can provide targeting solutions with their more accurate sensors.

The WFOV satellites are scheduled for launch as early as September 2022. Work on the HBTSS prototype contract will be complete in July 2023.

    Reform efforts in South Korea create ecosystem for defense industry growth

    By: Mike Yeo MELBOURNE, Australia — South Korea has over the past decade become a defense industry powerhouse in its own right, and it's seeking to widen its reach, with progress in international markets in recent years marking the maturity of its defense articles. This year's Defense News Top 100 list of the biggest defense companies in the world features four South Korean businesses. They are Hanwha (ranked 32rd), Korea Aerospace Industries (55th), LIG Nex1 (68th) and Hyundai Rotem Company (95th), all of which made last year's list. Continued reform The strong performance of South Korean defense companies comes in the wake of a series of reforms over the past decade, with the latest designed to consolidate industrial gains and create momentum for growth. The defense industry reforms are part of President Moon Jae-in's Defense Reform 2.0 program announced in 2018 — a complement to efforts seeking to create a slimmer, yet more efficient South Korean military that is less reliant on foreign defense technology. The push for further self-reliance is most prominent in Korea Aerospace Industries' KF-X program. KAI is developing a next-generation fighter for the South Korean Air Force. Although an American GE F414 turbofan will power the aircraft, its avionics will primarily be indigenous. These include the active electronically scanned array radar under development by Hanwha and the country's Agency for Defense Development, with support and some components supplied by Israel's Elbit Systems. Defense Reform 2.0 also puts emphasis on defense industry investment, and it comes as little surprise that the domstic market still takes up the biggest share of the pie where sales are concerned, backed up by the steady growth in defense spending: South Korea's defense budget grew 20 percent from 2009 to 2017, reaching $43 billion. Export success The reform program also places an increased priority on defense exports. The country is already successful in this area, with research by the Stockholm International Peace Research Institute think tank showing the country was the 11th biggest arms supplier in the world in 2017, with sales totaling $5.5 billion. In a further indication of how much South Korea's industry has grown, SIPRI also noted in a 2018 report that the country's defense exports grew 94 percent in the 10 years prior, a growth figure only bettered by Turkey for the same period. This growth has been underpinned by two of the highest-profile South Korean defense exports in the past decade: the KAI T-50 Golden Eagle family of trainer and light combat aircraft, and the Hanwha K9 Thunder self-propelled howitzer. The T-50 was earmarked by the Air Force as its mainstay advanced trainer and light combat aircraft. Despite losing a number of trainer competitions, including in Poland, Singapore and the United States, the Golden Eagle has since scored a number of notable contracts for export. Compared to its rivals in the trainer market, such as the Leonardo M-346 and the Boeing T-7, the main draw of the T-50 family is its combat capability in the form of the TA-50 and FA-50 equipped with sophisticated combat capabilities in the form of radars and precision weapons employment capability. This makes the aircraft attractive to nations unable to afford a high-end trainer with a light attack capability, and the list of the type's customers bears this out, with Indonesia, Iraq, the Philippines and Thailand operating the type in their respective air forces. The Philippine Air Force used its FA-50PH fleet to attack Islamic State militants in the southern part of the country in 2018. Meanwhile, Hanwha's K9 Thunder has carved a niche for itself in the global market for self-propelled howitzers. The 52-caliber, 155mm system has been selected by a number of NATO nations, beating out the similar Panzerhaubitze 2000 by Germany's Rheinmetall in Estonia, Finland and Norway. Turkey is building the K9 under license as the T-155 Firtina. The system has also been selected for license production by India and Poland, and had previously been selected by Australia in the early part of the 2010s only to be canceled following budget issues caused by the global financial crisis. Hanwha is also one of two companies left in the running to supply the Australian Army with a new infantry fighting vehicle. The AS21 Redback, which is based on the K21 vehicle operated by the South Korean Army, is to take part in an evaluation program against the Rheinmetall KF41 Lynx to supply 450 vehicles to replace M113 armored personnel carriers. The evaluation will see three of each vehicle delivered to Australia for testing, with the first two Redbacks due to reach Australia at the end of August, having left South Korea by ship late last month. Post-pandemic support Like much the rest of the world, the COVID-19 pandemic has hit South Korea hard, though the worst appears to be over for the country. The local defense industry was forced to adjust financially and operationally, and it remains unclear how revenue will be hit by the events of 2020. The pandemic has claimed at least one sale for the South Korean defense industry, with Argentina, which had appeared set to be the next customer for the T-50 family, deciding in April to put off the acquisition indefinitely. The South American country is yet to sign a contract, despite choosing the aircraft for purchase in July 2019. However, the South Korean government is not waiting for foreign action. Defense Minister Jeong Kyeong-doo has unveiled plans for the country to spend more on locally produced defense articles, partly as a move to help curtail the effects of the pandemic. Jeong said during a mid-June meeting with industry CEOs that his ministry plans to adjust spending plans to continue its drive to spend more on indigenous products, and move delivery timelines to reflect the reality of schedule delays while also waiving penalties for late payments. He also plans to expand an existing strategy aimed at establishing “defense industry innovation clusters”; this move adds to the first one established in April with an initial government investment. As a result, more funding will be made available to industry and research institutes, and will be used to support regional collaboration in defense-related research and development as well as manufacturing. https://www.defensenews.com/top-100/2020/08/17/reform-efforts-in-south-korea-create-ecosystem-for-defense-industry-growth

    Marines want a better way do force-on-force tactical shooting training

    After decades of using laser-type devices for shooting simulations and force-on-force tactical warfighting, the Marine Corps is asking for a new way to do fake shooting. A recent request for information is asking the commercial industry to bring ideas to the Corps that would help it make simulated shooting more realistic for up to a battalion-size force and improve current systems. Some versions of those systems have been in operation since Nintendo's Duck Hunt video game was considered high-tech shooting and laser tag advertisements dominated Saturday morning cartoons. This won't hit every Marine Corps installation but many will have it. Based on the RFI, the systems would be employed “to provide turnkey instrumented exercises with After Action Review (AAR) at 29 Palms, Camp Lejeune, Camp Pendleton, MCB Hawaii, MCB Okinawa or MCB Quantico within 3 weeks of notice, as well as support additional exercises upon request at Camp Fuji, Japan, Marine Corps Mountain Warfare Center, MCB Yuma, and specified reserve locations.” And the Marines are not doing this alone. They will be leveraging the Army's Live Training Engagement Component software. That's a tactical training framework so that simulations can be on the same standards and work jointly with other services and potentially foreign partners. One of the key cross functional teams that the Army formed last year included simulated training environment work. The goal is to incorporate better simulations for training at all levels, beginning in the design and procurement of future weapons and other equipment systems. The Corps wants a system that would be able to simulate all weapons and vehicles typically seen in a battalion, which would include at least: M4/M16; M9 or sidearm, the M27 Infantry Automatic Weapon; hand grenades; rocket propelled grenades; Light Anti-Tank Weapon; 60mm mortars; 81mm mortars; Claymore antipersonnel mine; Mk-19 grenade launcher; Russian machine gun; AK-47 variants; M41 TOW; Javelin missile and the Carl Gustaf recoilless rifle. It would distinguish between a hit, wound or miss and record information for after-action reviews. Marine Corps Times first reported news of this initiative last year following an interview with then-program manager for Training Systems at Marine Corps Systems Command, Col. Walt Yates. At the time, Yates described some of the shortfalls of using lasers when gauging accuracy and real-world effects. “A laser is at the speed of light, and the bullet is not,” he said. Yates previously said that though the current shooting systems are a generational change from old MILES, or multiple integrated laser engagement system, lasers have fundamental flaws for realistic battle scenarios. For example, laser-based systems shoot line-of-sight, making arcing weapons such as mortars and grenade launchers more difficult to simulate. Lasers can also be deflected by light concealment such as tree leaves and thin walls. And the number of troops and shooting ranges will change with new systems. The first generation ITESS accommodated 120 Marines and opposition forces, the second generation expanded to 1,500 with a communication radius of 5 to 8 km. The third seeks to track up to 2,500 Marines, making it capable of battalion on battalion exercises envisioned by the commandant, Yates said in the November interview. A new simulator must act more like a real bullet, requiring Marines to lead their moving targets, fire rifles on semi, burst and fully automatic modes and ensure the bullet travels in the realistic path, which is not perfectly line of sight, he said. https://www.marinecorpstimes.com/news/your-marine-corps/2018/06/04/marines-want-a-better-way-do-force-on-force-tactical-shooting-training/
