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.

    Military/Commercial Avionics Outlook Strong, Deloitte Says

    By Frank Wolfe The military and commercial outlook for avionics sales is strong, according to the author of a new Deloitte report, the 2020 Global Aerospace and Defense Industry Outlook. "The outlook for the aerospace avionics market is positive with good growth expected over the next few years, primarily due to the strong aircraft order book," Robin Lineberger, the leader of Deloitte global aerospace and defense, wrote in an email to Avionics International. "Moreover, all the major global militaries are increasing their spending on acquiring advanced military aircraft, further driving the growth for avionics," Lineberger wrote. Such aircraft include the Japanese F-3 twin-engine stealth fighter by Mitsubishi to replace the country's single-engine Mitsubishi F-2 jets and to complement the country's Lockheed Martin F-35s; the European Future Combat Air System (FCAS); and the United States Air Force's sixth generation fighter. In June at the Paris Air Show, Dassault Aviation unveiled an FCAS mock up, as government and company officials signed an FCAS Industry Agreement on Demonstrator Programs. The latter accord covers the main components of FCAS: a new generation, manned fighter; support "remote carrier" drones; and an Air Combat Cloud to integrate sensors. FCAS is to replace Dassault's Rafale fighter and the Airbus/BAE Systems/Leonardo-built Eurofighter. During the unveiling of the mock up, French President Emmanuel Macron said that he favors German-French-Spanish cooperation on FCAS with the British, which are developing their own advanced fighter through the BAE Systems Tempest program. In early October, the Air Force officially stood up a new program executive office to lead Digital Century Series, which will look to rapidly develop and field new aircraft beginning with the service's sixth-generation fighter. Last week, Will Roper, the Air Force's service acquisition executive, said that the new Digital Century Series initiative will look to improve integration of emerging technologies by buying smaller quantities of new fighter jets, potentially from multiple companies at a time. “Demand for military equipment is on the rise as governments across the globe focus on military modernization, given increasing global security concerns,” according to the new Deloitte report. “The uncertainty and sustained complexity of the international security environment worldwide is likely to boost global defense spending over the next five years.” In 2020, global defense spending will reach around $1.9 trillion, driven mainly by the U.S. but also countries such as China, Russia and India, the 14-page report says. It adds that NATO members in Europe, under pressure from the U.S., are also increasing defense spending to hit a target of 2 percent of GDP, and tensions in the Middle East are also driving demand for defense equipment. By 2023, global defense spending is expected to be $2.1 trillion, Deloitte said. Commercial and general aviation avionics sales are also expected to grow. "Demand for new and advanced flight capabilities from airlines and small general aviation aircraft owners to make flight operations more efficient and safer will continue to drive demand for commercial avionics," Lineberger wrote in his email to Avionics International. "Moreover, significant investments will be made on avionics because of government-mandated upgrades, for instance, the mandates for Automatic Dependent Surveillance/Broadcast capability (ADS-B), Head-Up Displays (HUD) and Controller/Pilot Datalink Communications equipment (CPDLC). However, there are some challenges which include longer product development cycle that leads to increased development costs." Urban air mobility, electric propulsion and fully automated flight decks are technology trends to watch in years ahead, according to the Deloitte report. "Although commercial aircraft manufacturers are increasingly relying on automated flight controls, including automated cockpits, the commercial aerospace sector is aiming to transition to fully automated flight decks," Lineberger wrote in his email. "Such a transition will likely reduce the number of crew members in the cockpit, resulting in lower costs for airlines. Moreover, automated flight decks would also address the growing pilot shortage issue currently faced by the aviation industry, which will likely be accentuated in the future as the commercial aircraft fleet continues to grow." https://www.aviationtoday.com/2019/12/04/military-commercial-avionics-outlook-strong-deloitte-says/

    Bell 407GXi earns instrument flight rules certification

    Bell Textron Inc., a Textron Inc. company, announced the Federal Aviation Administration (FAA) has issued an instrument flight rules (IFR) supplemental type certificate (STC) for the Bell 407GXi. The certification is a requirement for the Navy Advanced Helicopter Training System competition, enabling the Bell 407GXi to replace the Bell TH-57 Sea Ranger as the U.S. Navy's training helicopter. Bell's replacement bid offers a unique combination of capability, ease of transition, and low sustainment costs, giving the best value to the Navy. Should the Bell 407GXi be selected for the U.S. Navy Advanced Helicopter Trainer program, the company plans to conduct final assembly of the aircraft in Ozark, Ala. “The team did a great job ensuring the Bell 407GXi achieved the FAA's IFR certification necessary to meet all of the Navy's requirements,” said Mitch Snyder, president and CEO. “Bell is an instrumental part of the Navy's training program and has been for more than 50 years, and we look forward to continuing the tradition for the next generation of naval aviators.” A Bell to Bell transition offers low-risk to the Navy by streamlining instructor pilot and maintainer transition training as well as using common support equipment and infrastructure. The 407 airframe has already proven capabilities as the platform for the MQ-8C Fire Scout for the U.S. Navy. Bell's customer service and support has established capability with cost-efficient and effective helicopter training solutions. Bell proves its mature production and sustainment support capability every day by supporting more than 1,600 Bell 407s globally. These aircraft have nearly 6 million flight hours across the fleet and are actively performing flight training as well as military and para-public missions helicopter mission-set. The 407GXi's Garmin G1000H NXi Flight Deck enhances situational awareness and reduces pilot workload by delivering easy-to-read information at a glance. The Bell 407GXi's new IFR capability will allow all-weather operations while continuing to provide multi-mission capability safely, reliably, and effectively. The Bell 407GXi offers the lowest direct operating costs of any IFR-capable helicopter produced today. Combined with its proven performance, reliability, and ease of transition, the Bell 407GXi is the best value aircraft for U.S. Navy helicopter training. https://www.skiesmag.com/press-releases/bell-407gxi-earns-instrument-flight-rules-certification/

    Securing the final frontier: Digital twins, satellites and cybersecurity

    Kevin Coggins The United States and our allies are increasingly dependent on unfettered access to space. However, it has become abundantly clear that our space systems have significant cybersecurity vulnerabilities that our adversaries are eager to exploit. Earlier this year, William Akoto wrote about the growing constellations of satellites operated by private industry, led by SpaceX, Blue Origin and others: “If hackers were to take control of these satellites, the consequences could be dire. On the mundane end of scale, hackers could simply shut satellites down, denying access to their services. Hackers could also jam or spoof the signals from satellites, creating havoc for critical infrastructure. This includes electric grids, water networks and transportation systems.” Space Policy Directive 5, recently issued by the White House, notes that “cybersecurity principles and practices that apply to terrestrial systems also apply to space systems” and that we must integrate these principles and practices into every phase of the space system life cycle. SPD-5 is charting the right course toward assuring our cybersecurity in the space domain. This article highlights the unique vulnerabilities of space systems and how innovative solutions like “digital twins” can help us protect systems in orbit today and design more secure ones for the future. Cyberattacks on space systems — comprised of satellites, ground control stations, and user terminals (e.g., GPS receivers) — are appealing to nation-states, criminal groups, hackers and other bad actors. It's a tremendous opportunity to breach data and disrupt operations in a low-risk way with a low cost of execution. The different components that make up space systems each come with their own set of cyber vulnerabilities, the ground segment in particular. Some space systems were built with speed to market rather than cybersecurity in mind. In contrast, for traditional defense-focused space systems, a slower design and development process has introduced vulnerabilities as well. Space systems operating today may have taken a full 20 years to go from paper to launch and lack the capabilities to recognize or respond to today's cyberthreats. Space systems are increasingly interconnected — a malicious attack can easily spread from a single point of vulnerability in a ground station to the satellites. Cybersecurity in space systems has struggled to keep pace with the rapid evolution of threat actors and exploits. Given these challenges, how can organizations with space systems stay ahead of cyberthreats and protect their missions and users? The older approach of paper-based assessments has significant limitations, like the inability to duplicate reactions to all possible scenarios. At the other end of the spectrum, full-scale replicas are expensive and time-consuming to build. In the middle is the “digital twin” concept — a virtual mirror model that synchronizes a physical object with a cyber representation. With this approach, organizations can test a satellite in different scenarios to identify vulnerabilities and develop protection strategies, even before the satellite is built. One specific project that demonstrated digital twins' strengths and capabilities: testing Air Force GPS space systems for vulnerabilities after the passage of Section 1647 of the 2016 National Defense Authorization Act. Starting with a model-based system engineering review of thousands of pages of design documents, we built a digital replica of critical GPS Block IIR satellite components launched between 1987 and 2004 that ran on a single laptop with lightweight applications. Our digital twin created the foundation for a flexible cyber test bed — a suite of scalable software applications to demonstrate and validate cyber vulnerabilities and protection strategies as the system is designed or modified. The test bed can connect with assets beyond the network to generate data, provide war-gaming support and explore attack scenarios. We need this flexibility and functionality for future space system protection. The next generation of satellites will encounter more extreme service conditions and increased, simultaneous cyberattack vectors over longer periods of time. To respond to these challenges, these space systems will need increasingly complex designs, and with such complexity comes potentially greater vulnerability to cyberattacks and threats. Digital twins and model-based system engineering approaches can strengthen security throughout the acquisition and sustainment phases. Use them to: Develop system requirements and analyze design trades. Create test scenarios for requirements clarification and reference systems. Simulate threats, anomalies and impacts without risk to critical infrastructure. Assess the impact of new threats or operational scenarios on an on-orbit system design. What can space system acquisition professionals, developers and operators learn here? Digital twins offer an innovative approach that can streamline and strengthen the testing and design process of our space assets. They can also provide insights on as-built systems and enable the buydown of risks across the space system life cycle, enabling affordability across the entire system life cycle. Now is the time to leverage their capabilities, to ensure that the space infrastructure so vital to our security and American way of life has the protection it requires. https://www.c4isrnet.com/opinion/2020/11/02/securing-the-final-frontier-digital-twins-satellites-and-cybersecurity/
