  The US Navy is seeking upgrades for the F-35 radar’s sea-search mode

  By: David B. Larter and Valerie Insinna WASHINGTON — The U.S. Navy wants more from the F-35 jet's radar, which in sea-search mode is limited to what is directly in front of the aircraft, according to documents exclusively obtained by Defense News. According to the documents, the radar, Northrop Grumman's AN/APG-81 active electronically scanned array radar, can either hone in on a sector based on a specific point on the ground, or work in what is commonly known as “snowplow mode,” which, as the name suggests, searches everything in front of the aircraft. The Navy wants to be able to scan a wider area when in sea-search mode, something that the radar is currently not set up for, according to officials who spoke to Defense News. Officials also said the problem is on track for a solution, but may not be implemented until as late as 2024 with the Block 4 upgrades, notably adding that a solution will not be in place before a full-rate production decision on the F-35 this year. Ultimately, giving the Navy what it wants will be a matter of boosting computing power and upgrading software, officials explained. The issue is listed as a category 1 deficiency, according to the documents, which further define the limitation as something that means “adequate performance [is] not attainable to accomplish the primary or alternate mission(s).” The issue dates back to 2012, according to the documents. In this scale, category 1 represents the most serious type of deficiency. It's unclear why the issue is listed as a deficiency. The system is working in accordance with design specifications, according to both the documents and a statement from a Lockheed Martin executive. “The F-35's current radar sea search function meets the enterprises' expressed required specification," said Greg Ulmer, Lockheed Martin's general manager of the company's F-35 program. “As we modernize the F-35, we are bringing enhanced search capabilities, which represent an increase from the original requirements, and we stand ready to integrate the upgrade in the future, based on customer priorities and direction.” In an interview with Defense News, the head of the Pentagon's F-35 program office, Vice Adm. Mat Winter, said the issue was being resolved by software and computing upgrades, and there would be no requirement for a new radar. “We're not mechanically scanning, we're electronically scanning,” Winter said. “And being able to accurately scan the maritime environment, it just takes increased computing power, and that's what we're doing. ... It's a software fix, and then an allocation of computing power.” Winter may be referring to a planned bundle of computer upgrades called Tech Refresh 3, where the jet will get more modern computing systems that will increase the jet's processing power and memory. According to one document obtained by Defense News, TR3 is a prerequisite for a future radar fix. Those TR3-equipped jets won't roll off the production line until 2023. Defense News submitted written questions to the Defense Department's F-35 program office concerning these and other deficiencies, but it did not respond by press time, despite multiple follow-ups over a period of months. A retired fighter pilot, who reviewed the documents for Defense News and agreed to speak on condition of anonymity, agreed with Winter's assessment that the fix was likely software-based. Early on in the F/A-18's APG-79 AESA radar, there were glitches in the operation, but software updates smoothed out the system. Fixing the APG-81 should follow a similar track as the aircraft progresses, the pilot explained. “As long as the array itself is technically sound, I suspect over time they'll be able to find ways to continue to build out capability through software updates,” the retired fighter pilot said. https://www.defensenews.com/smr/hidden-troubles-f35/2019/06/12/the-us-navy-is-seeking-upgrades-for-the-f-35-radars-sea-search-mode/

  US Army picks winners to build light and medium robotic combat vehicles

  By: Jen Judson WASHINGTON — The U.S. Army has picked winners to build base platforms for its light- and medium-class robotic combat vehicles, according to a service statement released Jan. 9. The Army's Combat Capabilities Development Command and the service's Next Generation Combat Vehicle Cross-Functional Team “intends” — pending successful negotiations — to award a contract to QinetiQ North America to build four RCV-light prototypes and another contract to Textron to build four RCV-medium prototypes, the release stated. Through a rapid contracting mechanism, the National Advanced Mobility Consortium is coordinating the Army's awards to industry, and the service expects to be officially under contract with both companies by mid-February, according to the statement. While it was anticipated the Army would award up to two contracts per category at the end of the second quarter this fiscal year, it appears the awards have come earlier and are both limited to one company. The prototypes, according to the statement, will be used to “determine the feasibility of integrating unmanned vehicles into ground combat operations. The Light and Medium RCVs will be used to conduct a company-level experiment at the end of 2021." Results from that effort, as well as a platoon-level experiment in March 2020 and several virtual experiments, will help the Army decide in 2023 how it wants to proceed with robots on the battlefield. “Robots have the potential to revolutionize the way we conduct ground combat operations,” Brig. Gen. Ross Coffman, director of the NGCV CFT, said in the statement. “Whether that's giving increased fire power to a dismounted patrol, breaching an enemy fighting position, or providing [chemical, biological, radiological, nuclear and explosive] reconnaissance, we envision these vehicles providing commanders more time and space for decisions and reducing risk to soldiers.” Out of a large pool of whitepaper submissions, a Textron and Howe & Howe team, a team of QinetiQ North America and Pratt & Miller, HDT Global, and Oshkosh were each issued a request for prototype proposals in the RCV-light competition in October 2019. Three teams were picked to move on in the RCV-medium competition in November 2019: General Dynamics Land Systems, QinetiQ North America, and the Textron and Howe & Howe team. It is noteworthy that the companies selected to build prototypes in each category are the only two companies to have offerings in both the light and medium competitions, demonstrating potentially that they are the only companies with the flexibility to build in both categories. At the Association of the U.S. Army's annual conference in October, Textron and Howe & Howe dramatically unveiled their RCV Ripsaw M5, which is based on the latter's deep history of building unmanned ground vehicles, but adds technology like scalable armor and suspension as well as mobility options to cope with the challenges expected in the future fight. FLIR Systems is also part of the team, contributing its advanced sensors. “Bringing together Howe & Howe, Textron Systems and FLIR Systems really represents a dream team,” Textron CEO Lisa Atherton said in a statement released at the show. “We formed this team based on our shared focus to serve this customer with disruptive ideas and proven experience, and we are dedicated to meeting and exceeding their requirements through the RCV program.” The team told Defense News before the AUSA conference that it planned to submit a version of Ripsaw both for the light and medium variant of the Army's robotic combat vehicle. The Qinetiq and Pratt & Miller team submitted a variant of the Expeditionary Modular Autonomous Vehicle tailored toward the Army's RCV-light requirements. The offering combines Qinetiq's modular open-architecture control systems with Pratt & Miller's advanced mobility platform. The Army is also examining the utility of an RCV-heavy variant but is using robotic M113 armored personnel carriers as surrogate platforms for evaluations. That effort will focus on manned-unmanned teaming in a robotic wingman formation, with a manned Bradley Infantry Fighting Vehicle serving as the platform for the robot's operators. https://www.defensenews.com/land/2020/01/09/army-picks-winners-to-build-light-and-medium-robotic-combat-vehicles/
