  DOD budget pushing house cleaning pivot to leading-edge technologies: out with the old and in with the new

  Budget has $9.8 billion for cyber security and cyber warfare; $3.2 billion for hypersonics; and $800 million for artificial intelligence (AI) research. THE MIL & AERO COMMENTARY – The 2021 U.S. Department of Defense (DOD) budget proposal is out, and it looks like several years of consistent growth driven by the Trump Administration may be leveling off. A closer look, however, may indicate a pivot to new leading-edge technologies and away from legacy systems. DOD leaders in their fiscal 2021 budget request to Congress, which was released last month, are asking for $705.4 billion, which is down about 1 percent from this year's level of $712.6 billion. Before you conclude that the Pentagon budget has turned flat, however, take a look at where the money's going. First, the bad news: procurement. This is where big-ticket items like aircraft, combat vehicles, and ships get funding. The DOD's procurement budget request for 2021 is $136.9 billion, down nearly 7 percent from this year's level of $147.1 billion. Contained in the DOD budget for procurement, moreover, are aggressive cuts to legacy weapons systems. The U.S. Air Force, for example, will retire 24 RQ-4 Block 20 and Block 30 Global Hawk Battlefield Airborne Communications Node (BACN) unmanned aerial vehicles (UAVs) and Block 30 multi-intelligence aircraft UAVs next year.

The U.S. Army plans to eliminate 13 programs involving munitions, fires, protection, sustainment, mobility, mission command, and cyber programs that no longer are priorities. Additional cuts are expected. Next year the Navy plans no additional purchases of P-8A Poseidon maritime patrol aircraft; the MQ-4 Triton long-range maritime patrol UAV; or the MQ-25 Stingray UAV. The counterweight to these procurement cuts, however, is in the DOD's budget for research, development, test, and evaluation (RDT&E). As procurement spending is going down, the research budget is headed in the other direction. The Pentagon is asking for $106.6 billion, which is up about 1 percent from this year's research budget of $106.6 billion. Revealing is money is going. The DOD next year plans to spend $9.8 billion for cyber security and cyber warfare -- up 81 percent from $5.4 billion this year; $3.2 billion for hypersonics; $1.5 billion for military microelectronics and 5G networking; and $800 million for artificial intelligence (AI) research. Related: The new era of high-power electromagnetic weapons The Pentagon hypersonics budget will pay for research and development initiatives to develop the Army Long-Range Hypersonic Weapon; Navy Conventional Prompt Strike (CPS); and Air Force Advanced Rapid Response Weapon (ARRW). Research money also would include $1.1 billion for the Navy's next-generation frigate; $4.4 billion for the future Columbia-class ballistic missile submarine; and $464 million for two Large Unmanned Surface Vessels. The U.S. Defense Advanced Research Projects Agency (DARPA) is asking for $3.6 billion in 2021, a 3 percent increase from the $3.5 billion the agency received this year. DARPA has asked for $322.7 million for electronics research in 2021 -- a 1.7 increase from the 317.2 million the agency received this year. For sensors research, DARPA is asking for $200.2 million in 2021 -- a 26 percent increase over the $158.9 million the agency received this year. Related: Military researchers host industry day briefings for artificial intelligence (AI) and machine learning So, in short, it sounds like out with the old, and in with the new at the Pentagon. Four Navy cruisers that are at least 30 years ago are heading for retirement. Large, slow, and vulnerable Global Hawk UAVs are to be taken out of service, and Army programs no longer relevant amid today's global threats will be taken off the board. At the same time, enabling technologies considered crucial for today's military needs are on the upswing: hypersonic munitions and aircraft, cyber security and cyber warfare, 5G networking, and artificial intelligence. Perhaps the DOD has been due for a house cleaning like this for a while. Getting rid of obsolescent weapons systems makes sense because they're past the point of diminishing returns. Pumping more money into technologies for tomorrow's battlefield makes sense, too. These kinds of realignments are painful, yet essential. https://www.militaryaerospace.com/defense-executive/article/14168362/dod-budget-leadingedge-technologies-research

  DARPA Awards Contracts for Autonomous ‘Sea Train’

  11/2/2020 By Connie Lee The Defense Advanced Research Projects Agency has awarded contracts for its Sea Train program, which seeks to enable autonomous vessels to perform long-range transit operations. In September, Applied Physical Sciences Corp., Gibbs & Cox Maritime Solutions and Mar Technologies were chosen for the program, which will include two 18-month phases. The contract awards' total potential values were $31.2 million, $30.4 million and $28.5 million, respectively. Through the effort, DARPA wants “to provide some operational flexibility for medium-sized unmanned surface vessels,” said Andrew Nuss, a program manager within the agency's tactical technology office. Each company is “developing a unique approach to be able to address the goals of the Sea Train program.” Unmanned surface vessels are generally limited in operational range, typically 3,500 to 4,000 nautical miles, he said in an interview. However, DARPA hopes to extend that to about 14,000 nautical miles under the Sea Train program. Usually unmanned surface vessels must undergo multiple refuelings to go farther distances, he noted. “It's sort of a vicious cycle at that point, where you're constantly chasing efficiencies and whatnot,” he said. However, a Sea Train platform — which is expected to be 40 meters long and carry a 35-ton payload — could give an operational commander “the flexibility to deploy these highly capable medium-sized unmanned surface vessels from many different locations without having to rely on ... refueling operations.” DARPA plans to extend the range of USVs more efficiently by creating a “train” in which four autonomous vessels are physically connected until they reach their destination. The platforms would then detach, conduct their individual operations and then reconnect before returning to their starting point, Nuss said. Unmanned boats must overcome resistance and friction from waves as they move, but attaching the platforms may help increase their efficiency and allow them to travel longer distances, he said. “By physically connecting multiple vessels together, and extending the length of that interconnected system, we could move — in our case — four vessels with ... approximately the same efficiency of a single vessel,” Nuss said. The medium-sized platforms were picked for proof of concept, but the idea could be applied to smaller vessels or manned systems as well, he noted. https://www.nationaldefensemagazine.org/articles/2020/11/2/darpa-awards-contracts-for-autonomous-sea-train

  The next GPS payload will be fully digital

  By: Nathan Strout The navigation payload for the next iteration of GPS satellites has passed its critical design review, contractor L3Harris announced Feb. 11. According to the company, which is designing and building the system, the new payload will provide a more powerful, reliable and flexible GPS signal than previous satellites.The GPS IIIF satellites will follow the first 10 GPS III satellites—the first of which is already on orbit and operational. The Air Force plans to eventually build 22 GPS IIIF satellites. While the GPS III satellites use a 70 percent digital Mission Data Unit, the one in the new GPS IIIF payload will be fully digital. According to L3Harris, the new system will “provide more powerful signals and ensure flawless atomic clock operations.” “The digital payload is flexible enough to adapt to advances in GPS technology and future warfighter mission needs,” said Ed Zoiss, president of L3Harris' space and airborne systems. “Proceeding to the next stage in the GPS IIIF navigation payload development process moves the program closer to supporting evolving Air Force mission requirements.” With the critical design review complete, L3Harris can move forward with final development, test and delivery. The company has contributed navigation technology to every GPS satellite in orbit. While L3Harris is designing the navigation payload, Lockheed Martin is the prime contractor for GPS IIIF. The Air Force awarded Lockheed Martin more than $1.3 billion to build the first two GPS IIIF satellites in 2018. Critical design review for the platform is expected in March 2020, according to Space Force budget documents released Feb. 10. Once that is complete and the program passes Milestone C in the third quarter of FY2020, the Space Force will begin procuring additional GPS IIIF satellites with annual contract options. Delivery of the first GPS IIIF satellite is expected in 2026. Among their advanced features, GPS IIIF satellites will boast regional military protection capabilities, which allow them to deliver regionally-limited high-power M-Code signals. It will also include new laser retro-reflector arrays that can provide on orbit position determination. Furthermore, the GPS IIIF satellites are being designed to potentially incorporate technology from Navigation Technology Satellite 3, an Air Force Research Laboratory space vehicle that will be used to test a variety of position, navigation and timing technologies. L3 Harris is the prime contractor on that program, which recently passed its preliminary design review. https://www.c4isrnet.com/battlefield-tech/space/2020/02/12/the-next-gps-payload-will-be-fully-digital/
