  DARPA issues solicitation for moving-target recognition project

  Andrew Eversden WASHINGTON — The U.S. Defense Department's advanced research arm issued a broad agency announcement July 15 for technology that would use algorithms to identify moving military ground vehicles. The Moving Target Recognition program from the Defense Advanced Research Projects Agency's Strategic Technology Office is a “vital part” of DARPA's “Mosaic Warfare” vision, in which each weapon system is one “tile” in a large force package that overwhelms the adversary. For the program, DARPA is interested in algorithms and collection techniques that allow synthetic aperture radar, or SAR, sensors to “detect, geolocate, and image moving ground targets,” the announcement read. If the goals of the project are met, the MTR program will then work to develop automatic target recognition algorithms for the moving target images. “Emphasis is on military vehicle targets, including slow moving vehicles whose SAR signatures are superimposed on clutter,” the announcement noted. Test for moving target recognition will include airborne data collection experiments to test and evaluate the effectiveness of algorithms. Under the contract, performers will be required to provide the airborne radar sensors and flight services, while the government team will design experiments with moving ground vehicles. DARPA anticipates handing out multiple awards. The MTR program has two phases. Phase one will focus on SAR moving target detection, geolocation and imaging, according to the announcement. It has a performance period of two years and a six-month option. Phase two, which is solicited through the July 15 notice, will center on automatic target recognition. Second phase instructions will be provided to the phase one performers before the end of the phase one base period. No award amount was provided. The U.S. Army is also working through the challenges associated with advanced target recognition capabilities, such as ensuring that algorithms receive adequate and sufficient data to mature and learn. “If you're training an algorithm to recognize cats, you can get on the internet and pull up hundreds of thousands of pictures of cats,” Gen. Mike Murray, commander of Army Futures Command, said in June. “You can't do that for a T-72 [Russian tank]. You can get a bunch of pictures, but are they at the right angles, lighting conditions, vehicle sitting camouflaged to vehicle sitting open desert?” DARPA's mosaic warfare effort includes several other projects under the Strategic Technology Office, including one that would automate aerial dogfighting. The office is also developing two complementary systems that would identify combat systems in an area available for support missions and quickly plan their route to an area. https://www.c4isrnet.com/home/2020/07/21/darpa-issues-solicitation-for-moving-target-recognition-project/

  RFP Reveals Main Thrust Of U.S. Counter-Hypersonic Plan

  Steve Trimble The main thrust of the U.S. Missile Defense Agency's counter-hypersonic strategy has just been revealed. The Regional Glide Phase Weapon System (RGPWS) prototype project demonstrates an interception capability against a medium- or intermediate-range threat. The MDA revealed the existence of the program in a request for prototype proposals released to industry on Dec. 5. An industry day for the RGPWS prototype project is scheduled on Dec. 18 at an MDA facility on Redstone Arsenal, Alabama. The RGPWS shows the MDA is moving faster to field at least a prototype counter-hypersonic capability than previous efforts suggested. The MDA had previously defined a concept for a Hypersonic Defense Weapon System (HDWS). The agency selected 21 proposals from industry in September 2018 for concept definition studies. MDA then down selected to five concepts in late August and early September 2019 for a nine-month-long concept refinement phase. The selected proposals included four kinetic concepts based on existing boosters and one Raytheon-directed energy system. The RGPWS is a parallel effort by MDA to the HDWS. The companies selected for the HDWS concept refinement phase could submit separate proposals for RGPWS. But other companies that were rejected after the concept definition phase or did not participate in HDWS can participate in the RGPWS, says Tom Karako, director of the Missile Defense Project at the Center for Strategic and International Studies (CSIS), who was briefed on the program on Dec. 9. For example, Northrop Grumman's proposal was not down selected for the HDWS concept refinement phase, but it intends to compete for the RGPWS prototype project. “Northrop Grumman is engaged with MDA on Hypersonic Defense Regional Glide Phase Weapon System and will attend the upcoming industry day,” a spokesman says. Northrop has been developing kinetic and non-kinetic options for missile defense, including one concept in the latter category called the Terminal and Regional Electronic Attack Defense System. The acknowledgment of the RGPWS offers a limited glimpse into MDA's development strategy for the burgeoning counter-hypersonic capability. In July 2017, the agency first disclosed plans for funding a hypersonic defense demonstration. An item in the Selected Acquisition Reports for the Ballistic Missile Defense System added $508 million to the program's overall budget to pay for such a demonstration. In March 2019, the agency disclosed it would spend more than $600 million on hypersonic defense capabilities by the end of fiscal 2024. By emphasizing a “glide phase” weapon with a “regional” targeting area, the MDA also provided clues about the intent of the demonstration. It does not appear to be targeting an intercontinental ballistic missile with a nuclear hypersonic glide vehicle as the warhead, such as Russia's Avangard. It is more likely designed to target a hypersonic glide vehicle with regional range, Karako says. Options may include hypersonic glide vehicles on China's DF-17 and DF-21 missiles. “That's a good thing,” Karako says. “It's a smart move for MDA to start there.” Separately, the Defense Advanced Research Projects Agency continues to pursue the Glide Breaker program. It was revealed in July 2018 as a program with a particular interest in “component technologies that radically reduce risk for development and integration of an operational hard-kill system,” according to a DARPA solicitation document. But no further details about Glide Breaker have been released. https://aviationweek.com/defense/rfp-reveals-main-thrust-us-counter-hypersonic-plan

  130 House members want 24 percent more F-35s procured in FY21

  By: Aaron Mehta WASHINGTON — One hundred thirty members of the House of Representatives are asking key defense committees in Congress to increase the number of F-35 Joint Strike Fighters by 24 percent over the number requested by the Pentagon in fiscal 2021. “Our adversaries continue to advance surface-to-air missile systems and develop their own stealth fighters,” read the letter, released Wednesday. “It is essential that we continue to increase production of our nation's only 5th generation stealth fighter in order to ensure the United States maintains air dominance and to further reduce overall program costs.” The letter, addressed to the chairs of the Senate and House Armed Services committees and Appropriations Defense subcommittees, is authored by Reps. John Larson, D-Conn.; Marc. Veasey, D-Texas; Martha Roby, R-Ala.; and Michael Turner, R-Ohio — the four leaders of the bipartisan F-35 caucus. Last year, the four also joined forces to write a similar request, which garnered 103 signatories. The Defense Department's budget request asks for 79 F-35s, including 48 of the F-35A model used by the Air Force, 10 F-35Bs used by the Marines and 21 F-35C models used by the Navy. In the letter, the congressmen note that number is 19 less jets than Congress appropriated in FY20. However, that number creates “a capability gap that 4th Generation, or legacy, aircraft cannot fulfill,” the letter warned. “To reach the minimum 50% ratio of 5th Generation and 4th Generation fighters in the timeframe required to meet the threat, the U.S. must acquire F-35s in much larger quantities.” Instead, the members want a 24 percent increase in fighters procurement, going up to 98 total, including 12 more F-35As, two more F-35Bs and 26 more F-35Cs. Those numbers match the fighter increase listed by the Air Force in its unfunded requirements document sent to Congress earlier this year; the Navy requested only five more F-35C variants, while the Marines did not request more. The letter was first reported by Politico. In addition to the increase in planes bought, the members are seeking additional funding for “spare parts and depot level repair capability to meet the required availability rates and accelerate the stand-up of mandated, organic government repair capabilities.” Additionally, investments are sought for the program dedicated to the jet's reliability, maintainability and improvement, as well as a “long-term, outcome-based sustainment contract” that would guarantee performance metrics at a fixed price. The members then request the committees fully fund the budget request for the continuous capability development and delivery (C2D2) modernization effort and use existing funds to accelerate integration of the Joint Air-to-Surface Standoff Missile onto the jet. Earlier this year, the Pentagon's independent weapons tester called the current schedule for C2D2 “high risk” and said the program office is struggling to stay on schedule. “C2D2 is critical to meeting the evolving threat in the mid-2020s and into the 2030s. Full funding is needed for the delivery of new weapons and critical capabilities necessary to keep the F-35 ahead of our adversaries,” the members wrote. https://www.defensenews.com/congress/2020/03/19/130-house-members-want-24-percent-more-f-35s-procured-in-fy21/
