The Pentagon Is Powerful, But It Is Struggling To Kill The F-35’s Software Bugs

Here’s What You Need To Remember: While the F-35 continues to be an advanced fighter jet, there are times when it is clear that upgrading an old war bird like the B-52 is often a lot easier than working out the bugs in what should be a state-of-the-art fighter jet.

Introduced in the 1950s, the B-52 Stratofortress has remained in service thanks in part to the numerous upgrades it has received over the years. In fact, because it was introduced before the days of advanced computers, the B-52 has actually been at times much easier to update than more modern aircraft.

By contrast, the U.S. military’s highly advanced F-35 Joint Strike Fighter, which was developed with the latest and greatest aviation computer systems and software, has had no shortage of problems and bugs to work out, while upgrades have been anything but easy.

ALIS In:

Since its introduction, the F-35s ground-based ALIS logistical system, intended to streamline reporting and implement predictive maintenance, has for years remained buggy to the point of “dysfunctionality” – requiring constant manual inputs and workarounds when automated systems failed to do what they were supposed to do.

The problem with software has been so great that earlier this year, the U.S. Government Accountability Office (GAO) even warned that the F-35 Joint Strike Fighter program, despite producing more aircraft and at negotiated lower prices in 2019, is not meeting the standards that the aircraft’s customers might have expected.

The good news is that the F-35’s next tech upgrade could address many of the issues, but the bad news is that it could also just add billions more to the cost of the aircraft Ars Technica reported this week.

Third Time’s the Charm:

The Tech Refresh 3 program for the fifth-generation stealth fighter will include an upgrade of the jet’s core processor and memory as well as replacement of its Panoramic Cockpit Display. Other “improvements” will include a radar upgrade along with some hardware tweaks to the hardware for the weapons-handling.

As reported, the vast proportion of the upcoming updates will be in software – but that has also continued to be an Achilles’ heel of the F-35 program, in part because the updates have been delayed and often result in new issues including software conflicts that then need to be worked out.

Intelligence Aerospace also reported that the Pentagon’s goal to update the fighter’s software every six months via a Continuous Capability Development and Delivery (C2D2) program has also been unable to keep pace with the new increments of capability as planned. One serious issue has been that software changes, which have been intended to introduce a new capability or to fix a deficiency, has in fact tended to introduced stability problems and has even adversely affected other functionality.

Software Fixes:

If the new Tech Refresh 3 works as planned it could give new capabilities to the advanced stealth fighter. The software upgrades are mission-focused, and that includes new software that is meant to improve the aircraft’s electronic warfare capabilities and also allow the F-35 to expand its weapon load-out options, improve its electronic warfare capabilities, while the software upgrade should also add more safety for the pilot.

If the Tech Refresh 3 goes off as planned it could bring that new capability to the F-35 and address some of the larger issues. But it won’t solve every problem, notably the F-35’s Automated Logistics Sustainment System (ALIS), which has also reportedly been the source of frustration at the Department of Defense (DoD).

ALIS was developed as the fleet management backbone for the F-35, which could ensure an integrated interface to maintenance, supply chain and sustainment information. ALIS in theory could be the single management tool supporting all F-35 operations.

It also has had its own software problems, Ars Technica reported, and even worse problems caused by errors in the digital logs – the Electronic Equipment Logs – have resulted in the delivery of parts that were not ready to be installed, leading to hundreds of millions of dollars in additional costs.

Lockheed Marin is also reportedly continuing to work on fixes to the ALIS, but the DoD is now working to replace the system entirely with a cloud-based, jointly developed system, which has the colorful name Operational Data Integrated Network (ODIN). Add into that the GAO has already expressed concerns over ODIN however, citing a lack of clarity about the goals of the redesign of the fighter’s logical system.

While the F-35 continues to be an advanced fighter jet, there are times when it is clear that upgrading an old war bird like the B-52 is often a lot easier than working out the bugs in what should be a state-of-the-art fighter jet.
