How One Component Improved U.S. Navy F/A-18 Fleet Readiness
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.

Textron Aviation Defense announces $70.2M U.S. Air Force contract award for two Beechcraft AT-6 Wolverine aircraft, training and support services
Wichita, Kan. March 16, 2020 – Textron Aviation Defense LLC, a Textron Inc. (NYSE:TXT) company, today announced the finalization of a $70.2 million Other Transaction Authority (OTA) with the U.S. Air Force Life Cycle Management Center to equip the U.S. Air Force with two Beechcraft AT-6 Wolverine aircraft, pilot training, engineering services and up to four years of contractor support for maintenance and spares. The work in support of this OTA, which includes activities in support of military type certification, will take place in Wichita, Kansas. “Textron Aviation Defense is proud to equip the U.S. Air Force with the multi-role Beechcraft AT-6 Wolverine,” said Brett Pierson, vice president of Defense Strategy and Sales. “The AT-6 is a vital element of the National Defense Strategy to build ally and partner capacity, capability and interoperability — and does so at a fraction of the cost of other combat aircraft. We're eager to deliver the aircraft to the Air Force in support of Air Combat Command's (ACC) development of operational tactics and standards for exportable, tactical networks that improve interoperability with international partners.” This acquisition enables the U.S. Air Force to leverage a commercial off-the-shelf, non-developmental integrated weapons system to equip a multi-national coalition with a common system that meets a wide array of training and operational requirements. An affordable solution, the AT-6 cost per flying hour is less than $1,000 and its small maintenance footprint — as demonstrated during both phases of the Light Attack experiment — underscore the aircraft's cost-effectiveness, deployability and sustainability. “Our focus is on how a light attack aircraft can help our allies and partners as they confront violent extremism and conduct operations within their borders,” said Air Force Chief of Staff Gen. David L. Goldfein in a U.S. Air Force press release published upon the issuance of the request for proposal. “Continuing this experiment, using the authorities Congress has provided, gives us the opportunity to put a small number of aircraft through the paces and work with partner nations on ways in which smaller, affordable aircraft like these can support their air forces.” ACC will experiment with the AT-6 to further examine the ways in which a common architecture and intelligence-sharing network will connect platforms, sensors and weapons and deliver a digital network for light attack aircraft. “It's rewarding to equip U.S. and partner nations with an affordable, easy to maintain and highly effective tactical aircraft in this era of constrained military budgets,” Pierson added. “The U.S. Air Force and Navy flew the AT-6 during the Light Attack experiment, putting its combat-proven A-10 mission computer, Wescam MX-15 EO/IR sensor, Airborne Extensible Relay Over-Horizon Network (AERONet) and other capabilities to work, employing a substantial amount of ordnance, demonstrating aircrew re-fueling and re-arming at the Forward Arming and Refueling Point (FARP) and conducting other activities in support of experiment objectives. The AT-6 met all of the experiment's standards and proved itself as a high performance, austere field-capable aircraft that delivers unparalleled mission capability, deployability and sustainability.” About the Beechcraft AT-6 Wolverine The Beechcraft AT-6 Wolverine multi-role turboprop delivers the greatest level of mission configurability, the most advanced ISR technology and the utmost deployability and sustainability.
