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

By: Aaron Mehta Updated 3/20 at 6:45 PM EST with new comment from Bialos. WASHINGTON — The U.S. Defense Department has declared that defense contractors are “critical infrastructure” to national security, a designation that comes with an expectation to maintain a consistent, normal work schedule amid the outbreak of the new coronavirus, COVID-19. In a Friday memo to industry, Undersecretary of Defense for Acquisition and Sustainment Ellen Lord made it clear that she wants defense companies to continue to deliver their products and services to the Pentagon on time. “If you work in a critical infrastructure industry, as designated by the Department of Homeland Security, you have a special responsibility to maintain your normal work schedule,” Lord wrote. “We need your support and dedication in these trying times to ensure the security of this Nation. I understand that this national emergency presents a challenge and we are dedicated to working closely with you to ensure the safety of the workforce and accomplishments of the national security mission.” Lord also spelled out large swaths of the industrial base for which this order applies, including the aerospace sector; mechanical and software engineers; manufacturing/production workers; IT support; security staff; security personnel; intelligence support; aircraft and weapon systems mechanics and maintainers; suppliers of medical suppliers and pharmaceuticals; and critical transportation. Included in the designation are personnel working for companies as well as subcontractors who perform under contract for the department. Contractors who perform tasks such as providing office supplies, recreational support or lawn care are not considered essential. By designating the defense industry in such a way, companies involved may be able to get around state-directed shutdowns such as the one in New York right now. Similarly designated workers include, among many others, law enforcement, health care providers, water and power authorities, and IT support for emergency services — all of whom are still on duty in the current crisis. In the memo, Lord noted, companies involved should “follow guidelines from the Centers for Disease Control and Prevention as well as State and local government officials regarding strategies to limit disease spread.” Some companies have instituted work-from-home policies where applicable, although in cases such as production of defense equipment or work in secure facilities, that option appears unrealistic. Force of law? Things may not be as cut and dry as Lord's memo makes it seem, warned Jeff Bialos, a partner with the Eversheds-Sutherland law firm and former deputy under secretary of defense for industrial affairs. He notes that Lord's memo is based on guidance, put out the day before by the Department of Homeland Security, which does not carry with it the force of law to override decisions on work stoppage that may come from a state. “These are guidelines only. They do not have the force of effect of law,” Bialos warned. Bialos thinks the memo may be a useful tool for industry to turn to local governments that are eyeing a work shutdown and say they should be given an exemption. But should the local government decide not to grant that exemption, how much force the memo may have is unclear. “Thee's no slam dunk here. Everyone is struggling with these issues. And I think what this memo does is put another arrow in the quiver of a company that wants to keep doing business to meet defense needs. And it also is a document companies can provide to localities and states, and say ‘please give us an exemption.'” In a statement released late Friday, Lt. Col. Mike Andrews, a spokesman for Lord, said the undersecretary met today with Senate Armed Services Committee chairman Sen. Jim Inhofe, R-Ok., on the memo and other issues. Lord “remains committed to daily communication and collaboration with the defense industrial base, especially the defense industry trade associations. In addition, she'll be contacting several state Governors to discuss state-specific critical infrastructure and essential workforce efforts,” Andrews said, adding that a daily call between members of Lord's team and industry associations continues. Jerry McGinn, a longtime official at the department's Office of Manufacturing and Industrial Base Policy, said the move was the right one to make. “You're essentially trying to keep that workforce engaged and supporting that customer. This is trying to give DoD organizations flexibility to reduce contract disruptions, stop-work orders, and other actions that could impact the contractor workforce” said McGinn, now executive director of the Center for Government Contracting at George Mason University. “And that in general is a good thing. It's not something you want to do for six months, because then you might have trouble monitoring performance, but for this critical time it seems like a reasonable kind of thing to do.” https://www.defensenews.com/pentagon/2020/03/20/pentagon-declares-defense-contractors-critical-infrastructure-must-continue-work/
