  Integrated Hypersonic Plan Forms Amid Overlap Concerns

  WEST LAFAYETTE, Indiana—The U.S. Defense Department says data from an upcoming four-year test campaign covering 40 flights and three basic vehicle concepts will lay the foundation for a comprehensive hypersonic weapon road map that should allay growing congressional concerns over potential overlaps in costly weapons development capability. To a quarter of the tests, representing as many as 10 flights, will be focused on air-breathing scramjet-powered vehicles, says Mike White, assistant director for hypersonics at the Office of the Under Secretary of Defense for Research and Engineering. Speaking to Aerospace DAILY on the sidelines of the inaugural National Defense Industrial Association (NDIA) hypersonics capability conference at Purdue University here, White says test results from both boosted glide vehicle flights and powered missiles will form the basis for the integrated development plan. The overarching road map also will include the integration of a counter hypersonic development strategy, the preliminary steps toward which have been proposed by both the recently formed Space Development Agency (SDA) and the Missile Defense Agency. The SDA is studying a space-based distributed satellite architecture, while the latter has proposed a Hypersonic and Ballistic Tracking and Surveillance System (HBTSS). “Offensive and defensive coordination is my job,” White says. The bulk of the prototype tests will be conducted using the common hypersonic glide body (C-HGB). Developed by Sandia National Laboratories, the bi-conic re-entry vehicle has been adopted as the basis for near-term boosted glide weapons by the U.S. Air Force, Army and Navy, with only minor differences in each version planned to reflect the varying operational characteristics of each role. The Army, which plans to ground launch the Long-Range Hypersonic Weapon (LRHW) from transporter erector vehicles, is meanwhile making the first moves toward industrializing production of what up to now has been small batch manufacturing runs of experimental vehicles. The service has issued a solicitation for transition of the design and production capability of the initial prototype LRHW C-HGB variant out of Sandia into industry. A contract award is expected to be issued this month. Other versions of the C-HGB are in development for the Navy's vertically launched Intermediate Range Conventional Strike Weapon (IR-CPS), and the Air Force's Hypersonic Conventional Strike Weapon (HCSW). Underwater launch tests of the IR-CPS, which follows the successful Flight Experiment-1 test in October 2017, from the Pacific Missile Range Facility in Kauai, Hawaii, are due to run through 2024. The Air Force is scheduled to complete critical design review of the HCSW in 2020 prior to launch tests from a B-52. At least five other flight-test campaigns make up the remainder of the hectic four-year plan, three of which will be focused on the DARPA-led Tactical Boost Glide (TBG) vehicle and two proposed follow-on air-launched rapid response weapon (ARRW) vehicles in competitive development by Lockheed Martin and Raytheon. The balance are two air breathing vehicles, also in development by Lockheed/Aerojet Rocketdyne and Raytheon/Northrop Grumman, which will be evaluated under the Air Force's Hypersonic Air-Breathing Weapon Concept (HAWC) program. Despite the ongoing efforts to refine the hypersonic road map, the proliferation of prototype vehicle programs continues to cause concern in Congress. Warning that not all programs will receive the funding requested in the fiscal 2020 budget, Peter Visclosky, chairman of the House Appropriations Subcommittee on Defense, says some reductions are planned. Commenting at the NDIA event, he says, “Justifications in the budget for this effort receive the same scrutiny as every other program in the department and unfortunately certain aspects of that 2020 budget request were lacking.” Without identifying particular initiatives, Visclosky adds, “There were cuts to those specific programs where the justifications did not lead to a review. Each of the services impacted have been made aware of the issues that the committee has raised and the need to better define the strategy for the investment in these systems.” Visclosky also cautions that hypersonics, which is provisionally funded with a budget of $2.3 billion for fiscal 2020 and $10.5 billion over the period to 2024, also faces broader threats at a time of increased spending on other high-profile defense programs. “I am concerned about affordability in the future because this is a competitive process,” he said. “We have a nuclear modernization process that is underway and there is going to be a bulge in the federal budget. There is a new submarine and there is going to be a bulge in the budget. It is the same for the new [B-21] bomber under development and, while the Army doesn't have that ‘one' new program, collectively for the modernization program there is going to be one. “We need to make sure there is a concerted effort for commonality and collaboration to a common technical standard and system architecture. I think this will drive better affordability into the sustainment of the system,” he adds. https://aviationweek.com/defense/integrated-hypersonic-plan-forms-amid-overlap-concerns

  OMFV: Army Seeks Industry Advice On Bradley Replacement

  Having rebooted the Optionally Manned Fighting Vehicle program, the Army is now is asking industry input on how to achieve nine goals, from survivability to mobility to streamlined logistics. By SYDNEY J. FREEDBERG JR.on February 26, 2020 at 4:01 AM Two months ago, the Army cancelled its original solicitation to replace the M2 Bradley troop carrier after no company could meet the strict requirements. This afternoon, the Army officially asked for industry input on how to achieve nine broadly-defined “characteristics” for the future Optionally Manned Fighting Vehicle. “Feedback may be submitted in any form (concepts, information papers, technical papers, sketches, etc.),” says the announcement on SAM.gov. “The Army would like to obtain this initial feedback prior to 06 March 2020.” This call for suggestions on how to move forward comes just weeks after the Army issued a surprisingly apologetic survey asking industry what they did wrong the first time around. It's part of a newly humble approach in which the Army doesn't prescribe formal requirements up-front but instead lays out broad objectives and asks industry how best to achieve them. The chief of Army Futures Command, Gen. Mike Murray, gave reporters a preview of the nine characteristics three weeks ago, but the list announced today is much more detailed – though still leaving plenty of room for companies to brainstorm solutions. Our annotated highlights from the announcement – the emphasis is in the original: Background: The OMFV, as part of an Armored Brigade Combat Team (ABCT), will replace the Bradley to provide the capabilities required to defeat a future near-peer competitor's force. The Army is seeking a transformational increase in warfighting capability, not simply another incremental improvement over the current Bradley Fighting Vehicle. Concept of employment: As part of an ABCT, the OMFV will not fight alone, but rather as part of a section, platoon, and company of mechanized infantry.... “Near-peer competitor” is Pentagon jargon for “China or Russia” – chiefly Russia in this case, since the plains of Eastern Europe are a far more likely arena for armored warfare than Pacific islands. That the Army wants “transformational” improvements, not “incremental” ones, shows there's still some real ambition in the vision for this vehicle. At the same time, the OMFV will still fight “as part of an ABCT,” meaning the existing Armored Brigade Combat Team organization — not as part of some all-new organization with all-new equipment, as was once envisioned for the cancelled Future Combat Systems. Survivability. The OMFV must protect the crew and Soldiers from emerging threats and CBRN environments. The OMFV should reduce likelihood of detection by minimizing thermal, visual, and acoustic signatures. In other words, the vehicle needs to give the crew a chance of survival against cutting-edge anti-tank missiles, precision-guided artillery, attack drones and other such “emerging threats,” as chemical, biological, radiological, and nuclear contamination (CBRN). That does not mean the vehicle itself has to survive intact. The way this is worded, if a hit totals the OMFV but the soldiers inside can walk away, the Army will count that as a win. (The JLTV 4×4 truck takes this same approach to roadside bombs). So the OMFV doesn't necessarily have to have heavy armor protecting the entire vehicle. It could have a heavily armored crew compartment, light armor elsewhere, and an Active Protection System to intercept incoming threats. (The Russian T-14 Armata uses this combination). It also should avoid being spotted in the first place by eye, ear, or thermal sensor, which might favor designs with hybrid-electric motors that can switch from hot, noisy diesels to a battery-driven stealth mode. Mobility. The OMFV must have mobility that can keep pace with the Abrams in a combined arms fight through rural and urban terrain. That's the M1 Abrams main battle tank, which the existing M2 Bradley and M109 Paladin howitzer were also designed to keep up with. This is another aspect of that “concept of employment” that calls for the OMFV to slot into existing formations and work closely with existing vehicles. Note also the reference to “rural and urban terrain,” which will come up again: Traditionally the Army has avoided city fighting, but as urban sprawl covers ever more of the planet, technology and tactics have to adapt to brutal close-quarters combat. Growth. The OMFV must possess the growth margins and open architecture required for rapid upgrades and insertion of future technologies such as mission command systems, protection systems, and sensors. This characteristic is really where you get the potential for “transformational” improvements. The M2 Bradley was originally introduced in 1980 and, after 40 years of upgrades, it has very little margin left to handle additional weight or – even more important nowadays – power-hungry electronics. The Bradley's lack of room to grow has driven the Army to try replacing it three times already: the original OMFV requirements cancelled this year; the Ground Combat Vehicle cancelled in 2014; and the Future Combat Systems cancelled in 2009. Hopefully, fourth time's the charm. Lethality. The OMFV-equipped platoons must defeat future near-peer soldiers, infantry fighting vehicles, helicopters, small unmanned aerial systems, and tanks as part of a Combined Arms Team in rural and urban terrain. This is a more ambitious hit list than the Bradley, which sports machineguns for killing infantry, a 25 mm autocannon to destroy light armored vehicles, and the obsolescent TOW missile for taking on heavy tanks. The Pentagon is increasingly worried about small drones, which ISIS terrorists have used as flying IEDs and Russian artillery has used as spotters for barrages. With Russia and China developing increasingly sophisticated anti-aircraft systems, there's also a concern that US fighters may not be able to keep enemy attack helicopters at bay, forcing ground forces to handle that threat themselves. These aerial targets require more sophisticated tracking systems, and drones may be best dealt with by electronic jamming or lasers rather than bullets. Weight. The OMFV must traverse 80% of Main Supply Routes (MSRs), national highways, and bridges in pacing threat countries, and reduce the cost of logistics and maintenance. Designs must allow for future growth in components and component weights without overall growth of vehicle weight through modularity and innovation. Weight is the issue that has bedeviled Bradley replacements for two decades. The FCS vehicles, optimized for air transport, were too light to carry adequate armor; GCV was too heavy; and the original OMFV couldn't meet its air transport requirements and its protection requirements at the same time. With most bridges in Eastern Europe unable to safely take weights over 50 tons, too much heavy armor can cripple your mobility. Logistics. The OMFV must reduce the logistical burden on ABCTs and must be equipped with advanced diagnostic and prognostic capabilities. Advanced manufacturing and other innovative techniques should be included in the design that reduce the time and cost of vehicle repairs. There are two big factors that make a vehicle hard to keep supplied and in working order. One is weight – heavier vehicles burn more fuel – and the other is complexity. High-tech is usually high-maintenance. The US military is hopeful that AI-driven predictive maintenance can detect and head off impending breakdowns, and that 3D printing can produce at least some spare parts on demand without a long supply line. Transportability. The OMFV must be worldwide deployable by standard inter- and intra-theater sea, waterway, air, rail, and road modes of transportation. The original OMFV requirement very specifically called for two of the vehicles to fit on a single Air Force C-17 jet transport, which proved undoable with the weight of armor desired. This time, the Army isn't specifying any particular aircraft. In practice, armored vehicles are almost always shipped by sea and, where possible, stockpiled on allied soil well before a crisis erupts. On land, since tracked vehicles aren't designed to drive hundreds of miles by road, they're usually deployed to the battle zone by train or tractor-trailer, both of which have their own weight limits. Manning. The OMFV should operate with the minimal number of crew members required to fight and win. The OMFV should allow commanders to choose between manned or remote operation based on the tactical situation. This is the objective that gave the OMFV its name: Optionally Manned Fighting Vehicle. Now, since it's a Bradley replacement, the OMFV is supposed to be a troop carrier – specifically, the heavily armed and armored kind known as an Infantry Fighting Vehicle – so by definition it needs to carry people. But the Army is intensely interested in having the option to run it by remote control, or maybe even autonomously, to (for example) scout out especially dangerous areas or carry casualties back to an aid post without pulling healthy soldiers out of the fighting line. Training. The OMFV should contain embedded training capabilities that are compatible with the Synthetic Training Environment (STE). STE is the Army's total overhaul of its training simulators, drawing on commercial gaming technology to develop an array of virtual and augmented reality systems using a common database of real-world terrain. Instead of having to use a simulator in a warehouse somewhere, the Army wants troops to be able to run virtual scenarios on the same vehicles they'll actually fight with. All these characteristics are intertwined – and after its past troubles, the Army is acutely aware that maximizing one, such as protection, may compromise another, such as transportability. That's another thing the service wants feedback on, the announcement says: “The Army is interested in industry partners' ability to meet the desired characteristics and what trades” – that is, trade-offs – “may be necessary.” https://breakingdefense.com/2020/02/omfv-army-seeks-industry-advice-on-bradley-replacement
