The Pentagon is racing against inflation for military might

By: Aaron Mehta

WASHINGTON — In 2017, the top two officials at the Pentagon — then-Defense Secretary Jim Mattis and then-Chairman of the Joint Chiefs of Staff Gen. Joe Dunford — testified to Congress that the defense budget needs to have 3-5 percent annual growth over inflation each year through 2023 to ensure America's military success.

Dunford, speaking to the Senate Armed Services Committee in June 2017, went as far as to say: “We know now that continued growth in the base budget of at least 3 percent above inflation is the floor necessary to preserve just the competitive advantage we have today, and we can't assume our adversaries will remain still."

Three years later, as the Trump administration prepares to unveil its fiscal 2021 budget request on Feb. 10, such growth appears impossible. The budget is expected to be largely flat, as a two-year budget deal reached last summer calls for $740 billion in defense spending in the next fiscal year, up just $2 billion from the enacted FY20 amount.

“The 3-5 percent goal was reasonable enough and absolutely needed,” said Mackenzie Eaglen, a budget analyst with the American Enterprise Institute. “But it is not happening. The defense top line for 2021 is negative real growth, aka declining.”

Susanna Blume, a defense analyst with the Center for a New American Security, said that certain parts of the defense budget, particularly maintenance and personnel costs, grow faster than the rate of inflation. “That's what's behind these comments about requiring a certain amount of real budget growth in order to sustain the joint force as it is today,” she said.

But there is a wild card, according to Ellen Lord, the Defense Department's top acquisition official: a series of reform efforts led by now-Defense Secretary Mark Esper, which so far have accounted for $5 billion in savings.

“We're getting more and more efficient. That is obviously what Secretary Esper is focused on with his defensewide review, that we are cutting out administrative tasks and a variety of portions of programs to make sure we return those savings to our critical modernization efforts such as [artificial intelligence], hypersonics and so forth,” Lord said during a Jan. 31 news conference at the Pentagon. “We are always having to look very carefully at our budgets and make sure we triage them to focus on the critical few. So we're always concerned, but we're always going to work it.”

How much of that expected growth gap can be filled by Esper's efficiency drive is difficult to pin down. Blume said its “certainly possible that efficiencies could make up some of that gap,” but whether the work that has been done now and is planned in the near term will be enough “are questions we don't have answers to today.”

Added Eaglen: “Efficiencies alone will not get the Pentagon its 3-5 percent growth in actual dollars to reinvest. The defensewide review only yielded $5 billion, and the way it works with these drills is that the money doesn't necessarily move from pot A to pot B as a result."

“But that doesn't mean it is not worth doing. Any money amount is helpful. And the exercise is also about getting the bureaucracy to shift its time, tasks and attention to great power competition as much as it's about shifting funds into higher priorities that support the strategy,” Eaglen said.

If one of the Pentagon's big bets work out, that could be a real game-changer, Blume said. Those bets include efforts to replace a Defense Logistics Agency warehouse using a 3D printer as well as attempts by the Air Force to rapidly develop, prototype and produce fleets of planes. If one of them goes well, Blume said, “you can potentially start to bend some of those cost curves.”

New Materials Architectures Sought to Cool Hypersonic Vehicles
Hypersonic vehicles fly through the atmosphere at incredibly high speeds, creating intense friction with the surrounding air as they travel at Mach 5 or above – five times faster than sound travels. Developing structures that can withstand furnace-like temperatures at such high speeds is a technical challenge, especially for leading edges that bear the brunt of the heat. To address this thermal challenge, DARPA recently announced its Materials Architectures and Characterization for Hypersonics (MACH) program. The MACH program seeks to develop and demonstrate new design and material solutions for sharp, shape-stable, cooled leading edges for hypersonic vehicles. A Proposers Day describing the program will take place January 22, 2019 in Arlington, Virginia: https://go.usa.gov/xEcEy. “For decades people have studied cooling the hot leading edges of hypersonic vehicles but haven't been able to demonstrate practical concepts in flight,” said Bill Carter, program manager in DARPA's Defense Sciences Office. “The key is developing scalable materials architectures that enable mass transport to spread and reject heat. In recent years we've seen advances in thermal engineering and manufacturing that could enable the design and fabrication of very complex architectures not possible in the past. If successful, we could see a breakthrough in mitigating aerothermal effects at the leading edge that would enhance hypersonic performance.” The MACH program will comprise two technical areas. The first area aims to develop and mature fully integrated passive thermal management system to cool leading edges based on scalable net-shape manufacturing and advanced thermal design. The second technical area will focus on next-generation hypersonic materials research, applying modern high-fidelity computation capabilities to develop new passive and active thermal management concepts, coatings and materials for future cooled hypersonic leading edge applications. Both technical areas will be described in a Broad Agency Announcement solicitation expected in mid-January 2019 on DARPA's FedBizOpps page here: http://go.usa.gov/Dom. The MACH program seeks expertise in thermal engineering and design, advanced computational materials development, architected materials design, fabrication and testing (including net shape fabrication of high temperature metals, ceramics and their composites), hypersonic leading-edge design and performance, and advanced thermal protection systems.

GA-ASI Conducts Japan Coast Guard Validation Flights
General Atomics Aeronautical Systems, Inc. (GA-ASI) announced that it will partner with Asia Air Survey (AAS) to hold a series of validation flights for the Japan Coast Guard (JCG) featuring GA-ASI's SeaGuardian beginning in mid-September. The purpose of the flights is to validate the wide-area maritime surveillance capabilities of RPAS for carrying out JCG's missions, including search and rescue, disaster response, and maritime law enforcement. The flights are expected to run for approximately two months and will include support from the Japan Maritime Self Defense Force (JMSDF) at its Hachinohe base in Aomori Prefecture. According to the JCG, the flight validation will be conducted in accordance with “The Policy on Strengthening the Maritime Security Systems,” using Unmanned Aerial Vehicles to perform maritime wide-area surveillance using new technology. “We're pleased to support the JCG's goals of validating SeaGuardian's maritime surveillance performance,” said Linden Blue, CEO, GA-ASI. “We know there is a need in Japan and worldwide for affordable, long-endurance airborne surveillance in the maritime domain.” The SeaGuardian system will feature a multi-mode maritime surface-search radar with Inverse Synthetic Aperture Radar (ISAR) imaging mode, an Automatic Identification System (AIS) receiver, and High-Definition – Full-Motion Video sensor equipped with optical and infrared cameras. This sensor suite enables real-time detection and identification of surface vessels over thousands of square nautical miles. The featured Raytheon SeaVue surface-search radar system provides automatic tracking of maritime targets and correlation of AIS transmitters with radar tracks. https://www.uasvision.com/2020/07/09/ga-asi-conducts-japan-coast-guard-validation-flights/

First European-Built F-35 For The Netherlands Presented
Being Built For Lockheed Martin By Leonardo Company The first F-35 (009), which will be based in the Netherlands from this fall, was officially presented recently in Cameri, Italy. There, the Italian company Leonardo is building the new fighter plane for manufacturer Lockheed Martin. The Italian aircraft manufacturer has a production line for wings and a final assembly line on which it assembles complete aircraft. State Secretary Barbara Visser and her colleague Mona Keijzer from Economic Affairs and Climate were present at the ceremony. "With the F-35 and later also the MQ-9 Reaper, the Air Force will get the nicest things that others are looking forward to. And it will be a wonderful year for Leeuwarden," Visser said. "In just 49 days, on 31 October, the Air Force will receive this aircraft there. It is fantastic that we work together in Europe to build the aircraft, but also to later maintain it." "A perfect example of how national security and economic affairs go together", Keijzer said. "The F-35 brings prosperity to the Netherlands in defense, economic growth and business innovation." Aircraft "009" will remain in Italy for a few more weeks, including for some test flights. "We accept the aircraft, and will then transfer it to the Air Force as quickly as possible. The less it remains with us, the sooner the user can get started with it," said Director Defense Equipment Organization, Vice Admiral Arie Jan de Waard. In Cameri, Leonardo is building the F-35A for both its own air force and 29 units for the Netherlands. With the distribution of the largest contracts some 10 years ago, it was agreed that Italy would be assembling the aircraft while The Netherlands does the engine maintenance of at least the Italian and Dutch F-35s. That happens at the Woensdrecht Logistics Center, where the European storage location for parts of the F-35 is also located. In Cameri the four main components of an F-35 are assembled. Leonardo itself builds one of those components, the wing section. Part of these is used for the on-sire final assembly process, but the vast majority goes to the Lockheed Martin factory in the United States. There, they are used to assemble aircraft for America, Australia, Denmark, Norway and South Korea, to name a few. For the Netherlands, other F-35s are currently on the production line in Italy at various stages. The next one, the F-010, is expected to also come to the Netherlands this year. The delivery of the final aircraft is now scheduled for mid-2023; The Netherlands will then have 37 aircraft. http://www.aero-news.net/getmorefromann.cfm?do=main.textpost&id=f92e55c3-7e8e-4b56-9a0d-64e829ad8c50
