Hypersonic threats need an offense-defense mix

By: Melanie Marlowe

Next week, people from across the missile defense community will gather at an annual symposium in Huntsville, Alabama, to consider how to adapt U.S. missile defense efforts to the challenge of renewed competition with Russia and China. A centerpiece of their discussions will be the emergence of advanced hypersonic missile threats and what to do about them.

Over the past few years, the Pentagon has prioritized the development of offensive hypersonic strike weapons, with billions of dollars in contracts already awarded for each of the major military services to acquire hypersonic strike missiles of their own.

The counter-hypersonic mission, however, received surprisingly short shrift in recent defense budgets, with progress on hypersonic defense thus far piecemeal and halting. Some leading military officials charged with procuring hypersonic strike missiles have said that defending against hypersonic missiles is too hard, so we shouldn't even try.

That short-sighted approach is at odds with the vision of newly confirmed Secretary of Defense Mark Esper, who stated to Congress that he will advocate hypersonic missile defense, to include the development of new sensors, interceptors, and advanced command-and-control systems.

Public commentary on hypersonic threats has been somewhat hyperbolic. Yes, hypersonics are fast — five or more times the speed of sound — but that's slower than many ballistic missiles. Aerodynamic maneuver makes for a less predictable flight path, but this also means that atmospheric friction would remove the kind of decoys that might accompany a ballistic reentry vehicle. Whether a boosted glide vehicle, a scramjet cruise missile or a maneuverable quasi-ballistic missile, hypersonics pose a complex air defense challenge, but they are not invulnerable.

The strategic significance of hypersonics is nevertheless quite real. Today's Patriot, Terminal High Altitude Area Defense and Aegis defenses protect American carrier groups and ground forces against aerial and ballistic missile attack. Designed to go around or under those defenses, hypersonics are a more sophisticated means to hold forces at risk, and thereby undermine our broader defense goals and alliance system. Even if the United States catches up with the Chinese and Russians on hypersonic strike, our adversaries' ability to hold U.S. carriers and forward bases at risk will push back U.S. forces. They could certainly also be used to target the American homeland, but the more urgent threat is regional. Passive defense only goes so far — ships can only go so fast, and air bases cannot be moved. Active defenses must be part of a balanced strategy.

The first priority here is a space sensor layer. Unlike ballistic missiles, hypersonic missiles fly at lower and changing altitudes, are harder to see, and travel an uncertain flight path. Current early warning satellites can detect the launch of boost-glide vehicles but are unsuited to tracking them during the glide phase. Today's surface-based ballistic missile radars would only be able to spot a weapon once it crosses the horizon. Only space sensors can provide birth-to-death, fire-control quality tracks for hypersonic missiles.

Unfortunately, recent budget requests have been rather tepid in their commitment to space sensors. The administration's 2020 request virtually divested the program, and for the second year in a row the Missile Defense Agency listed the space sensor layer as its No. 1 unfunded priority. Thankfully, Congress seems to be in the process of restoring $108 million to return the program to the MDA to move out on development this year.

The second element of hypersonic defense is interceptors. Although existing interceptors may well be improved, Secretary Esper has affirmed that new interceptors will have to be developed that are better suited to the mission's stressing thermal and high-maneuver environment. The MDA's third-highest unfunded priority for 2020 — $720 million for hypersonic defense — seems unlikely to be restored this year, but should be restored in the 2021 budget. Directed-energy weapons could potentially target hypersonic threats in their cruise phase or jam them in their terminal phase, but the mission's complexity will almost certainly require both kinetic and nonkinetic effectors.

The most challenging element will be developing a command-and-control architecture that ties everything together. A long-range hypersonic glide vehicle of significant range could cross continents and multiple combatant commands. Even with better interceptors and an adequate sensor layer, information and fire-control solutions must be developed and rapidly passed to commanders. The Command and Control, Battle Management, and Communications network that supports the Ballistic Missile Defense System may be the foundation of such an architecture, but more dramatic upgrades will be required.

The advent of the hypersonic era is central to the efforts by Russia and China to counter U.S. power projection in the world. The Pentagon's recent focus on hypersonic strike is necessary but insufficient. It falls now to congressional leadership and those assembling the 2021 budget to rebalance it with a more appropriate mix of hypersonic strike and defense.

DARPA wants commanding robots to work like a video game
By: Kelsey D. Atherton In a fake city in Mississippi, DARPA is training robots for war. In December 2019, at a camp southeast of Hattiesburg, hundreds of robots gathered to scout an urban environment, and then convert that scouting data into useful information for humans. Conducted at Camp Shelby Joint Forces Training Center, the exercise was the third test of DARPA's OFFensive Swarm-Enable Tactics (OFFSET) program. OFFSET is explicitly about robots assisting humans in fighting in urban areas, with many robots working together at the behents of a small group of infantry to provide greater situational awareness than a human team could achieve on its own. The real-time nature of the information is vital to the vision of OFFSET. It is one thing to operate from existing maps, and another entirely to operate from recently mapped space, with continuing situational awareness of possible threats and other movement through the space. Dating back to at least 2017, OFFSET is in part an iterative process, with contractors competing for and receiving awards for various ‘sprints,' or narrower short-turnaround developments in coding capabilities. Many of these capabilities involve translating innovations from real-time strategy video games into real life, like dragging-and-dropping groups units to give them commands. For the exercise at Camp Shelby, the swarms involved both ground and flying robots. These machines were tasked with finding specific items of interest located in buildings at Camp Shelby's Combined Arms Collective training Facility. To assist the robots in the field experiment, organized seeded the environment with AprilTags. These tags, which are similar to QR codes but trade complexity of data stored for simplicity and robustness in being read at difference, were used to mark the sites of interest, as well as hazards to avoid. In practical use, hazards seldom if ever arrive with barcodes explicitly labeling themselves as hazards, but for training the AprilTags provide a useful scaffolding while the robots coordinate in other ways. “As the swarm relayed information acquired from the tags,” wrote DAPRA, “human swarm tacticians adaptively employed various swarm tactics their teams had developed to isolate and secure the building(s) containing the identified items.” That information is relayed in various ways, from updated live maps on computer screens to floating maps displayed in real time in augmented reality headsets. As foreshadowed by countless works of cyberpunk fiction, these “human swarm tacticians” interfaced with both the real world and a virtual representation of that world at once. Commanding robots to move in real space by manipulating objects in a virtual environment, itself generated by robots exploring and scouting the real space, blurs the distinction between artificial and real environments. That these moves were guided by gesture and haptic feedback only further underscores how deeply linked commanding robots can be to augmented reality. The gesture and haptic feedback command systems were built through sprinter contracts by Charles River Analytics, Inc., Case Western University, and Northwestern University, with an emphasis on novel interaction for human-swarm teaming. Another development, which would be as at home in the real-time strategy game series Starcraft as it is in a DARPA OFFSET exercise, is the operational management of swarm tactics from Carnegie Mellon University and Soar Technology. Their developments allowed the swarm to search and map a building on its own, and to automate resource allocation in the process of accomplishing tasks. For now, the heart of the swarm is as a scouting organism built to provide information to human operators. https://www.c4isrnet.com/unmanned/2020/02/11/darpa-wants-commanding-robots-to-work-like-a-video-game

Norway’s defense minister: Ensuring collective defense and deterrence in the northernmost corner of Europe
By: Frank Bakke-Jensen A serious security crisis in the northernmost corner of Europe would affect all of NATO. That is why the alliance just conducted the largest full-scale military exercise in decades— in Norway. In October and November, some 50,000 soldiers from 31 countries were engaged in a major exercise designed to test our ability to operate together in crisis or war. Around 65 ships, 250 aircraft and as many as 10,000 vehicles took part. Exercise Trident Juncture 2018 demonstrated NATO's revitalized focus on collective defense of its member states and the geopolitical importance of Europe's northern flank. Trident Juncture 2015 took place in the Mediterranean region. This year's Trident Juncture was a unique opportunity for NATO and our partners Sweden and Finland to test and further develop our ability to operate together in the north. Norway's rugged terrain, intricate coastline and demanding climate represent challenges in and of themselves to the war fighter, making this one of the reasons why it is so important to train here. Not just because it makes us better at defending ourselves, but also because it strengthens the bond between our countries and sends a strong signal to anyone who may want to use military power to force our will. The fact that 31 countries contributed to the exercise proves that we, as an alliance, stand together. Even more importantly, the exercise demonstrated our will and determination to come to each other's aid, should it ever be necessary. With Trident Juncture 2018, we have shown in a very visible way that we will come to the aid of any member nation, should any of us need it. We see no military threat against Norway today. However, we have seen a more assertive Russia with both the will and the ability to use military power to achieve political goals. Cyberattacks and disinformation are fueling political polarization in both Europe and the United States, which in turn is challenging democratic institutions and our ability to compromise. International terrorism is changing how we think about security; migration has emerged as perhaps the No. 1 dividing force; and climate change is affecting all of these issues in ways we cannot fully predict. As members of a successful alliance, we all share a common responsibility to maintain peace and stability in our neighborhoods — from the north to the south. Democracy, rule of law, freedom of speech and freedom of religion, as well as a rules-based world order, are at the heart of our nations. All 29 allies participated in exercise Trident Juncture. All 29 allies stand together in our 360-degree approach to security. And all 29 allies share the burdens of collective defense and deterrence. These are the fundamental values that make us capable of reacting to a rapidly changing security environment. We are firm believers in dialogue, transparency and a predictable world order based on international law and binding agreements. Unfortunately, we see that these values are increasingly challenged. That is why it is necessary to have a credible military capability. While Denmark, Norway and Iceland are members of NATO, Sweden and Finland are not. By including Sweden and Finland in a NATO exercise, we improve our ability to act together as neighbors. The Nordic contribution to Exercise Trident Juncture was substantial, with over 13,000 soldiers and a large number of civilian personnel. In a fine example of Nordic cooperation, army elements from Finland operated as part of a Swedish brigade, and Danish helicopters supported the Norwegian brigade. NATO and partner forces from Finland and Sweden used military bases and airfields in all the Nordic countries, with the strategically important Iceland serving as a central hub, gateway and staging area for deployment and sustainment of allied forces across the north Atlantic. From a Norwegian perspective, Trident Juncture 18 has been a success. For the first time in decades, the whole alliance came together in the High North to test reinforcement plans and to demonstrate that we are committed to collective defense. In addition, the sea lanes across the Atlantic are once again seen as vital. Being a host nation, with all it entails, is a daunting task for a small nation like Norway. With this exercise, we were able to test our abilities to receive and accommodate allied forces. All units were in position, with their equipment, on time. All supplies were delivered as planned. The infrastructure was satisfactory. In addition, we were able to put our total defense concept to the test. More than 50 other Norwegian actors — governmental as well as nongovernmental — were involved. Seen with Norwegian eyes, Exercise Trident Juncture 18 has contributed to continued stability in the High North. Frank Bakke-Jensen is Norway's defense minister. https://www.defensenews.com/outlook/2018/12/10/norways-defense-minister-ensuring-collective-defense-and-deterrence-in-the-northernmost-corner-of-europe/

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/
