  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/

  Lockheed unveils pared-down F-35 trainer with same software capability but a 90% reduced footprint

  Lockheed Martin spent its own money developing this LITE trainer over the last 18 months after hearing signals from F-35 customers that they needed more training capacity for less cost.

  Fully autonomous ‘mobile intelligent entities’ coming to the battlefields of the future

  By: Kelsey Atherton WASHINGTON — A killer robot by any other name is far more palatable to the general public. That may be part of the logic behind the Army Research Laboratory Chief Scientist Alexander Kott's decision to refer to thinking and moving machines on the battlefield as “mobile intelligent entities.” Kott pitched the term, along with the new ARL concept of fully autonomous maneuver, at the 2nd Annual Defense News Conference yesterday, in an panel on artificial intelligence that kept circling back to underlying questions of great power competition. “Fully autonomous maneuver is an ambitious, heretical terminology,” Kott said. “Fully autonomous is more than just mobility, it's about decision making.” If there is a canon against which this autonomy seems heretical, it is likely the international community's recent conference and negotiations over how, exactly, to permit or restrict lethal autonomous weapon systems. The most recent meeting of the Group of Governmental Experts on Lethal Autonomous Weapons Systems took place last week in Geneva, Switzerland and concluded with a draft of recommendations on Aug. 31st. This diplomatic process, and the potential verdict of international law, could check or halt the development of AI-enabled weapons, especially ones where machines select and attack targets without human interventions. That's the principle objection raised by humanitarian groups like the Campaign to Stop Killer Robots, as well as the nations that called for a preemptive ban on such autonomous weapons. Kott understands the ethical concern, drawing an analogy to the moral concerns and tradeoffs in developing self driving cars. “All know about self driving cars, all the angst, the issue of mobility... take all this concern and multiply it by orders of magnitude and now you have the issues of mobility on the battlefield,” said Kott. “Mobile intelligent entities on the battlefield have to deal with a much more unstructured, much less orderly environment than what self-driving cars have to do. This is a dramatically different world of urban rubble and broken vehicles, and all kind of dangers, in which we are putting a lot of effort.” Full article: https://www.defensenews.com/smr/defense-news-conference/2018/09/06/fully-autonomous-maneuver-coming-to-the-battlefields-of-the-future
