F-35A Lightning IIs are the first single engine fighters capable of performing rapid crew swaps, in which a pilot takes off, flies a mission and lands to refuel while another pilot takes over the cockpit of the same jet.
During wartime, crew swaps allow a steady stream of rested and capable fighter pilots to rotate into the fight. And while the crew swaps could help cut down on maintenance work, problems with the F-35′s next-generation maintenance software reportedly linger.
“Other aircraft like bombers, tankers, helicopters, and twin engine fighters have been doing ‘hot crew swaps’ for some time. Until now, it hasn’t been safe to do with a single engine fighter, but the F-35’s maintenance-friendly design provided Airmen here an opportunity to develop this capability,” Col. Michael Miles, 388th Maintenance Group commander, said in an ACC news release.
“Flying more sorties with less down-time proves the capability of the F-35 to fly sustained combat operations,” Maj. Caleb Guthmann, the 388th Fighter Wing’s director of staff and an F-35 pilot, said in the release. “It gives us more time in the air to target bad guys and protect friendlies.”
Rapid crew swaps will potentially reduce the time it takes to generate a new sortie by up to two hours, according to 1st Lt. Ryan Naluai, assistant officer in charge of the 421st Aircraft Maintenance Unit.
“The jet’s systems report on the health of the aircraft as it is flying and after it lands. So, under these conditions, we can confidently put it back up in the air again immediately without doing a full post-operation inspection,” Naluai said in the release. “It’s a testament to the reliability of the F-35 and the proficiency of our maintainers.”
Three full F-35 squadrons are eventually planned to fly out of Hill AFB, according to the ACC release. The rapid crew swaps will help during peacetime, as the Air Force works to condense sorties into shorter periods of time, keeping the flightline moving.
The F-35 program oscillates between good and bad news. The crew swaps are the positive end of the spectrum, while news that the Autonomic Logistics Information System, or ALIS, is still not working as intended sits on the negative end.
ALIS is the F-35′s next-generation software designed to detail maintenance issues on the jet. Maintainers plug the ALIS into the aircraft to diagnose performance issues and streamline the process of identifying replacement parts.
While the system has been advertised as a game-changer in aviation maintenance, “it does not yet perform as intended,” the Pentagon’s operational and live fire test office said in its 2018 report.
Among the complaints: “Users must employ numerous workarounds due to data and functionality deficiencies. Most capabilities function as intended only with a high level of manual effort by ALIS administrators and maintenance personnel,” the report reads. “Manual workarounds are often needed to complete tasks designed to be automated.”
That report also criticized the accuracy of the internal 25mm gun “as installed in the F-35A, to be unacceptable.”
Air Force Chief of Staff Gen. Dave Goldfein was unconcerned when asked about the cannon’s accuracy by reporters.
“Given what we built the F-35 to do, I’m not sure the gun is what we should focus on,” Goldfein said at a Brookings Institute event in February. “When we talk about fifth-generation, stealth is actually only a small part of that. … It’s about information fusion."
