  Interservice rivalries: A force for good

  By: Susanna V. Blume and Molly Parrish It's no secret that the military services fight hard to protect their shares of the defense budget. Just last week, Chief of Naval Operations Adm. Michael Gilday made his case for a greater share of the defense budget. Army Secretary Ryan McCarthy quickly answered, making the same claim on behalf of his service. What if the Department of Defense were able to use these rivalries as a force for good? The secretary of defense should pit the services against each other in a healthy competition for solutions to real operational challenges. The reward? More funding in their budgets to implement the best solutions. It is by now old news that the 2018 National Defense Strategy solidified a shift in priorities from long-term counterinsurgency and stabilization operations in the Middle East to strategic competition with China and Russia. This shift represents a significant change in what the country will require of the joint force in the future. As a result, to fully embrace this shift in priorities, it follows that the services must accept additional risk in some areas in order to invest in the capabilities required to sustain U.S. military advantage over aspiring great powers. In other words, in order to implement the NDS, the DoD must shift resources. But shifting resource around with the defense budget is really hard. For the most part, defense budgets are built from the bottom up, with each program having strong institutional champions, regardless of how relevant that program is to the current strategy. In this environment, it's difficult to take money away from something to give it to something else. The result is budgets that largely reflect the status quo. While the DoD should of course avoid capricious and destabilizing swings in funding for defense programs, there are times when deliberate, strategy-driven shifts in resources are necessary. To make it a little easier to move money around the DoD in these cases, we recommend in our latest report that the secretary of defense harness interservice rivalry as a force for good. The secretary should give the services specific operational challenges to solve at the outset of the budget cycle, and reward the service or services with the best solutions at the end of the cycle with the funds to implement them. The DoD competition would start at the beginning of the budget cycle, with the operational challenge given alongside the usual strategic, planning and fiscal guidance. Over the course of the budget cycle, the services would each work to come up with solutions to the operational challenges posed by the secretary. During program review, the services would present their solutions to defense leadership. The service or services with the best solution to the secretary's challenges would then receive the funds to implement them. To fund this competition, the secretary would have to hold back some resources at the start of the process, effectively giving less to each of the services to begin with. This decision will be extremely unpopular with the services, but it will also ensure that the secretary has easily accessible funding available to him or her at the end of program review with which to ensure that the services are implementing his or her top priorities. The idea of spurring innovation through competition is not new. The DoD already uses competitions to drive innovative solutions to a wide variety of technical challenges. Take the Defense Advanced Research Projects Agency's Launch Challenge, which aims to improve resiliency in space by tasking participants to “launch payloads to orbit on extremely short notice.” DARPA will give the team who is able to complete both launches a prize of $10 million to continue their work. In addition, this past September, the DoD's Joint Artificial intelligence Center, along with the National Security Innovation Network, hosted a Hackathon at the University of Michigan. Participants came from both academia and the commercial industry to find artificial intelligence-enabled solutions. The hackers were given a specific problem and then tasked with finding a solution. The winners of the Hackathon are rewarded with — surprise — money! The services like money just as much as the average citizen, and the Department of Defense needs to take this concept and use these persistent and unavoidable interservice rivalries as a force for good. A healthy competition between the services, incentivized by funding, could be the next step toward implementing and addressing the challenges inherent in implementing the National Defense Strategy. https://www.defensenews.com/opinion/commentary/2020/01/21/interservice-rivalries-a-force-for-good/

  Navy Hires Boeing To Develop A Very Fast And Long-Range Strike Missile Demonstrator

  The Navy will use the new high-speed demonstrator to help refine its requirements for future stand-off anti-ship and land-attack missiles. oeing has received a contract to help develop a ramjet-powered high-speed missile demonstrator for the U.S. Navy. The company says that the design will aid the service in identifying requirements for future air-launched missiles, possibly ones able to reach hypersonic speeds, that its F/A-18E/F Super Hornets and other combat aircraft within its carrier air wings will be able to employ against targets on land or at sea. The company's Defense, Space & Security division announced that the Naval Air Warfare Center Weapons Division (NAWCWD), part of Naval Air Systems Command (NAVAIR), had awarded it this contract, worth approximately $30 million, on Oct. 20, 2020. The work will be conducted under what is officially called the Supersonic Propulsion Enabled Advanced Ramjet (SPEAR) program. The goal is to conduct the first flight of the demonstrator in late 2022. "We have a talented team of engineers to meet the challenging technical demands and schedule timeline that the SPEAR program requires," Steve Mercer, the Program Manager at Boeing for the SPEAR effort, said in a statement. "We look forward to working with Navy experts to advance technologies for the Navy's future capabilities." It's not entirely clear what kind of missile demonstrator the Navy is looking for exactly for the SPEAR program. The acronym includes the word "supersonic," but Boeing's press release cites its prior work on the X-51A Waverider, an experimental air-breathing hypersonic vehicle that featured a scramjet engine. Hypersonic speed is generally defined as anything above Mach 5. At the same time, Boeing also highlighted its work on "the Variable Flow Ducted Rocket propulsion system under the Triple Target Terminator program in 2014." The Triple Target Terminator program, or T-3, which the Defense Advanced Research Projects Agency (DARPA) led, explored concepts for very-long-range air-launched missiles that would be able to engage hostile aircraft, cruise missiles, and air defense threats on the ground, hence the name. A Variable Flow Ducted Rocket propulsion system is a kind of rocket ramjet, a relatively well-established concept at its core, in which gas produced by burning a source of solid fuel is mixed with compressed air fed into a combustion chamber via a duct or air intake to produce thrust. Advanced designs that allow for varying the flow of gas into the combustion chamber make it possible to throttle the thrust and adjust the speed of the vehicle the ramjet is powering. With this in mind, it's worth noting that NAWCWD issued a request for information regarding "Solid Fuel Ramjet Propulsion Manufacture/Test" in March, though it is unclear if that contracting notice is related in any way to SPEAR. In addition, Boeing's press release says that it will "co-develop" the SPEAR demonstrator, but it's unclear if this means another company is involved in the effort or that the Navy's own engineers and scientists will be directly assisting with the work. The website of the Naval Aviation Systems Consortium (NASC) lists a contract award to the company relating to the SPEAR program on Aug. 31, valued at just over $32 million, but for the demonstrator's airframe only. NASC "has been formed to support the technology needs of the Naval Air Warfare Centers (NAWCs) and the Naval Air Systems Command (NAVAIR) through the use of Other Transaction (OT) Authority," according to the site. There is no mention of this award in the Pentagon's daily contracting announcement for Aug. 31, which is supposed to include any deal valued at more than $7 million. The SPEAR contract that Boeing has just announced also does not appear in today's notice, so it's unclear when the Navy formally awarded these two contracts and whether or not they are, in fact, the same one. The War Zone has already reached out to Boeing for more information about its involvement in the SPEAR effort. Whatever the company's role in the project is or isn't, the press release certainly indicates that it will be a stepping stone to the development of future anti-ship and land-attack missiles that will be integrated onto aircraft in the Navy's carrier air wings. This includes the services F/A-18E/F Super Hornets, another Boeing product, a significant number of which eventually slated to go through the Block III upgrade program, which will add a host of advanced features that you can read about in more detail in this past War Zone piece. At the same time, the clear indication is that any operational weapons that follow-on from the SPEAR effort could be added to the arsenal of the service's F-35C Joint Strike Fighters, as well. An F/A-18E Super Hornet, at left, and an F-35C Joint Strike Fighter, at right, share space on the flight deck of the Nimitz class aircraft carrier USS Abraham Lincoln during tests in 2018. "The contract award comes after the Department of Defense requested information from the defense industry to help the Navy determine technical requirements of future carrier-based land and sea strike weapons systems," Boeing's press release said. "The SPEAR flight demonstrator will provide the F/A-18 Super Hornet and carrier strike group with significant improvements in range and survivability against advanced threat defensive systems," Mercer, the firm's SPEAR program manager, added. Very-long-range, high-speed strike weapons could be very valuable for the Navy's carrier air wings, especially as potential near-peer adversaries, such as China and Russia, continue to develop and field increasingly longer-range and otherwise more capable surface-to-air missile systems and associated radars and other sensors. Aircraft carriers and their associated strike groups and air wings are also increasingly at risk from various anti-access and area-denial capabilities, further underscoring the need for weapons with greater range and that are able to prosecute targets faster to help ensure their survival. At present, the primary air-launched stand-off anti-ship and land-attack missiles available to them are the AGM-84D Harpoon anti-ship cruise missile, the AGM-84H/K Standoff Land Attack Missile-Expanded Response (SLAM-ER), and the AGM-158C Long Range Anti-Ship Missile (LRASM), all of which are subsonic. The service is in the process of developing the AGM-88G Advanced Anti-Radiation Guided Missile-Extended Range (AARGM-ER), which will have at some surface strike capabilities and will also serve as the basis for a Stand-in Attack Weapon (SiAW) for the U.S. Air Force. However, the exact speed and range of this weapon are unclear. The Navy is also developing a powered cruise missile derivative of its AGM-154 Joint Stand-Off Weapon (JSOW) glide bomb. Boeing's SPEAR announcement comes as the U.S. military as a whole is pursuing a wide array of new hypersonic strike weapons, including unpowered boost-glide vehicles and air-breathing missiles. The Air Force is working toward its own "Expendable Hypersonic Multi-Mission Air-Breathing Demonstrator" as part of a program called Mayhem, which is linked to work on advanced turbine-based combined cycle engines. That service is also working closely with DARPA on the Hypersonic Air-breathing Weapon Concept (HAWC) project and its own Hypersonic Attack Cruise Missile (HACM) effort. Lockheed Martin, which is leading the development of the HAWC missile, has proposed a follow-on design for use by the Navy in the past. In August, the Air Force had said it was looking at designs from Boeing, as well as Lockheed Martin and Raytheon, to meet a requirement for "a solid-rocket boosted, air-breathing, hypersonic conventional cruise missile, air-launched from existing fighter/bomber aircraft." It's not clear if that announcement was related to HACM or not, but the following month, Boeing released a computer-generated promotional video featuring a B-1 bomber firing what the company described as a notional hypersonic missile. The company has subsequently released a more detailed still rendering featuring this conceptual missile that, at least visually, appears to be an air-breathing design. All told, it's hardly surprising that the Navy is also in the process of pursuing its own high-speed strike missiles to arm its carrier aircraft. There's no reason to believe that the weapons that emerge from SPEAR won't be suitable for integration onto land-based platforms, such as the service's P-8A Poseidon maritime patrol aircraft, as well. Whatever SPEAR's final design looks like, it's an important step forward for the Navy in providing this capability to its combat aircraft fleets in the future. https://www.thedrive.com/the-war-zone/37170/navy-hires-boeing-to-develop-a-very-fast-and-long-range-strike-missile-demonstrator
