Arlington, Va., December 4, 2019 - FLIR Systems, Inc. (NASDAQ: FLIR) announced that its Kobra™ robot has been chosen for the United States (U.S.) Army's Common Robotic System-Heavy (CRS-H) program. The five-year production contract to build upwards of 350 unmanned ground vehicles (UGVs) is worth up to $109 million. This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20191204005221/en/ The CRS-H program will give the Army a ‘program of record' to build and sustain a fleet of large UGVs for years to come. The CRS-H platform calls for a robot weighing up to 700 pounds. Army Explosive Ordnance Disposal (EOD) units will use the system to perform a range of missions, such as disarming vehicle-borne improvised explosive devices (VBIEDs), unexploded ordnance, or related heavy-duty tasks. A variety of sensors and payloads also can be added to the UGV to support other missions. “We are pleased to be selected for the U.S. Army's CRS-H program and deliver lifesaving robotic technology to our soldiers,” said Jim Cannon, president and CEO at FLIR. “This award exemplifies why we acquired Endeavor Robotics earlier this year — to capture strategic programs of record that enable us to integrate advanced solutions for the warfighter, give us the fuel to grow our business, and strengthen our position as a leader in unmanned systems.” Over several months and two rounds of testing, the Army compared the FLIR Kobra with other vendor systems. Entrants were evaluated on robot reliability, maneuverability, and usability, among other factors before Kobra was selected as the winner. Previously, in 2017 the Army chose FLIR's legacy business, Endeavor Robotics, as its medium-sized UGV provider through the Man Transportable Robotic System Increment II (MTRS Inc II) contract. FLIR is delivering its Centaur™ UGV under this on-going program. “Our CRS-H platform will give soldiers a powerful, extremely mobile, yet highly transportable UGV, ready to deploy at a moment's notice to keep them out of harm's way,” said David Ray, president of the Government and Defense Business Unit at FLIR. “This win is a testament to our employees who've designed such an advanced, multi-mission UGV. We look forward to working with the Army to get this robot into the field and deployed with our warfighters.” FLIR Kobra delivers unmatched strength, power, and payload support in an easy-to-operate robot package. Kobra has a lift capacity of 330 lbs. (150 kg.) and can stretch up to eleven-and-a-half feet to access hard-to-reach places. Ready for indoor and outdoor use, Kobra maintains mobility on tough terrain and can overcome obstacles such as jersey barriers. The award covers a five-year production period with shipments beginning in the second quarter of 2020. For more on FLIR Systems' Unmanned Ground Systems platforms, visit www.flir.com/UIS/UGS.

The U.S. Navy's F/A-18 and EA-18G fleets have experienced a dramatic turnaround. In 2017, less than half of the Navy's Boeing F/A-18 Super Hornets were able to fly. Now, 80% of its carrier-based fighters are ready for missions. The solution involved fixing a single component within the General Electric F414 engine. The Navy faulted constrained spending following the 2008 financial crisis and increased demand from the wars in the Middle East as reasons for the fleet's lack of readiness. More specifically, those conditions exacerbated an issue embedded in the military's vast supply chain. For 20 years, the Super Hornets and EA-18G Growlers have continually had electronic systems and new sensors added that placed greater and greater demand for power from its General Electric engine. That demand taxed a key component of the F414's electrical power generation system—its generator control unit (GCU), which keeps the generator output within a specified range. Initial attempts to address the GCU's issues through “component-level reliability improvements were not sustainable,” Navy spokeswoman Gulianna Dunn tells Aviation Week. Eventually, the GCU, already in short supply, failed to keep pace, causing a cascading effect on the availability of the carrier-based fighters. In the words of a Navy program official, the GCU was the “top platform degrader for all naval aviation.” When sequestration-era spending limits were imposed on the Pentagon in 2013, the entire military faced across-the-board funding cuts, including the operations and maintenance accounts. The Navy had to make tough choices about what bills it would pay and what to defer. At the same time, flight hours for the Super Hornet and Growler in the Middle East increased to meet the high operational tempos of Operation Enduring Freedom and Operation Inherent Resolve. As the Navy reduced aviation sustainment budgets, the program office did not have sufficient funding to purchase spare parts. From fiscal years 2013-16, the program office requested between $193.6-311.5 million and received between $85.2-136.3 million, according to a 2019 Defense Department Inspector General report. To compensate, Navy officials cannibalized aircraft to obtain the required spare parts. Maintainers removed working parts from an aircraft and installed them on a second jet to make that aircraft operational. A backlog of spare parts exacerbated fleet readiness and availability rates—an issue that affected the GCU acutely. New mission payloads created new types of electrical load, straining the aircraft's electronics, and wearing out the GCU at a faster rate. The second-generation (G2) and G3 GCU models that equipped the fleet could handle only about 150 flight hours. To increase reliability General Electric Aviation Systems, in consultation with the Navy, began working to redesign the GCU. A G3-to-G4 conversion kit could reach up to 532 flight hours. A G4 GCU was even better—sustaining 1,220 flight hours. Naval Air Systems Command (Navair) flight-tested the G4 in August 2015, and GE started production in mid-2016, Joe Krisciunas, general manager and president of GE Aviation Electrical Power Systems, tells Aviation Week. But the part was still only being manufactured at a minimal rate. The matter came to a head in October 2018, when then-Defense Secretary Jim Mattis set an 80% mission-capable readiness goal. At the time, only 260 F/A-18 and EA-18G aircraft were capable of flying missions—approximately 60%, far short of the mandate. In response, the Navy convened a Reliability Control Board (RCB) in 2019 to improve the F/A-18 and EA-18G mission-capable rate. The board pinpointed the main problem—insufficient production of the F414's GCU. The Navy had 200 of the units on back order. Navair worked with GE to ramp up GCU production, according to Lt. Cmdr. Jason Shaw, power and propulsion lead at the F/A-18 and EA-18G program office. The RCB determined GE was producing roughly six GCUs per month that would funnel into the program office, Boeing or Naval Supply Systems Command (Navsup). The program and Boeing had predictable delivery schedules, but Navsup would only receive GCUs that were produced beyond what the other two contracts required. “It created a hole on the supply shelf,” Shaw says. “When a jet would lose a GCU, there was no other one to replace it from supply.” The team brainstormed and decided GE would increase production to about 21 GCUs each month, while Navair would defer a contract for 320 GCU conversion kits to 2021. Pushing the contract would leave room for Navsup to acquire a more predictable delivery schedule. The company doubled its GCU production rate from 2018 to 2019, and almost doubled it again in 2020 to reach the 21 units per month rate, Krisciunas says. These courses of action resulted in zero GCU back orders by mid-June 2020. Additionally, the team is working with GE to resolve production issues related to GCU testing capacity. The plan is to purchase new, larger test stands and upgrade software on existing test equipment. This would allow the company to conduct more tests and further increase production. The test stand is a large electric motor that simulates the engine spinning the gearbox, and it has a pad that duplicates the GCU interface. A test stand costs approximately $1.5-2 million and typically takes 15-18 months to get up and running, Krisciunas says. Still, more improvements are being made: The program office is now assessing wiring issues that may have also contributed to low GCU reliability. The service awarded a $17 million contract to purchase additional software and cables for Automated Wiring Test Sets, which will allow aircraft mechanics to identify system faults. “The U.S. Navy is the only [Pentagon] military branch to have met and sustained the 80% readiness call that Mattis put out, and that is largely associated with resolving the issues with GCUs,” Shaw says. https://aviationweek.com/defense-space/aircraft-propulsion/how-one-component-improved-us-navy-fa-18-fleet-readiness
