Is the $400 Billion F-35's 'Brain' Broken? (cnn.com)
Zachary Cohen, reporting for CNN News: Almost 2,500 of the world's most advanced warplanes, with a total price tag of $400 billion, and they may not have a "brain" in the bunch? That's the fear of federal watchdogs who say problems with the F-35 Joint Strike Fighter's complex logistics software system could lead to a grounding of the entire fleet, not to mention future cost increases and schedule delays. Documenting risks to the F-35's Autonomic Logistics Information System, which Department of Defense officials have described as the "brains" of the fifth-generation fighter, an April 14 Government Accountability Office report says a failure "could take the entire fleet offline," (PDF) in part, due to the lack of a backup system. The report also outlines concerns related to the lack of testing done to ensure the software will work properly by the time the Air Force plans to declare its version of the aircraft ready for deployment this August and the Navy reaches that milestone in 2018. The Marine Corps declared the first squadron of its F-35 variant ready for combat in July 2015, with the intention of upgrading and resolving the software issues before its first planned deployment in 2017.
Amazing how that isn't clear to everyone by now.
as the Common Affordable Lightweight Fighter. I sometimes wonder about back in the days when fighter jets were being cranked out from the factories like Toyota cranking out Corollas. There was a time of where it took multiple flights to take out a target (most attacks on bridges fail along with a lot of friendly fire incidents), a time of Aces, test pilots that can list zillions of different aircraft to their resume, etc. These days just a few drones are needed. There was an article about new grads from USAF basic pilot school and waiting list for positions like F16 squadrons were lengthly. Some signed up immediately for drone piloting, one said though they don't get to fly the "real thing" but you don't want to be in the horse calvary when the tank comes along.

Estimated to cost approximately $16.7 billion over the aircraft's 56-year lifespan, the logistics software system is considered one of the three major components that make up the F-35, along with the airframe and engine.
Unlike the airframe and engine, however, the software is not built into the plane itself. Instead, it runs on ground computers to support operations, mission planning, maintenance and sustainability.
So...
1. Unlike when you take your car to the shop, they won't be able to have the plane tell them what's wrong.
2. If CSC updates the servers and breaks it (like the usually do to ours), there are no backups.
The "Brain" is actually the pilot and the software that displays threats, targets and kills them is apparently working correctly.
When Fascism comes to America, it will call itself Anti-Fascism, and tell you to give up your guns.

Actually you were more right the first time when saying the problem was created by Congress. It isn't the industry's fault at all and certainly isn't the CEO's faults. Congress said thou shalt build one plane to rule them all. One plane to find them, one plane to bring them all in and in the darkness bind them.
The industry is simply bidding on the contracts that Congress is making. And in this case, then dealing with all the feature creep that Congress has caused by telling the Air Force, Navy, and Marines that they all need to use this one plane to replace all their existing needs.... There was a reason we had specialized planes for specialized purposes. A plane that is carrying several tons of bombs will not do so well when having to dog fight against other planes. A plane that has VTOL capability will have a lot of space taken up by all the extra power plant requirements needed for having enough thrust to lift straight off the ground and/or hover for landing. A plane that has short, foldable wings to be able to fit more onto an aircraft carrier will have more structural drawbacks than airframes that do not have foldable wings.
It is all the feature creep to make a single plane that does everything which is the problem. Don't blame the industry. The industry didn't invent these requirements. Someone who has zero technical ability said to someone else wouldn't it be great if all our planes were the same because then we could save on maintenance and training costs because it is all the same platform, and a bunch of other people which no technical ability looked at the numbers for projected cost savings over the lifetime of the airplanes and said yes, that would save money. But none of those people looked at the technical challenges and costs involved in engineering a single plane that could do everything that 5-6 existing planes do when they said replace all those existing planes with just a single one which does all the same roles that those other planes could do, only better...
We were all warned a long time ago that MS products sucked, remember the Magic 8 Ball said, "Outlook not so good"
Autonomic Logistics Information System (ALIS) is the 'maintenance' software system, stuff like parts inventories, maintenance and airframe systems status, scheduling, blah.
Unnecessarily complex. It does not do targeting, battle communications, flight control, or pilot extension, something that is described as handled by 'sensor fusion software'. However, it is issuing false alarms for radar system capability, which occurs during flight, including combat. This impacts the pilot...
Also, the parts management system misorders parts, which seems inexcusable. Your Chevy dealer does better, by all accounts.
Since 2014 this software has been described as having so many problems and being so complex that "it needs to be treated “like its own weapon system.”"
Maintainers have said 80 percent of issues identified by ALIS are "false positives."
And then this tidbit:
"The ALIS system is currently computer racks totaling about 1,000 pounds, and was too big to be used during carrier testing. The program is developing a deployable, two-man portable version of the system that will be ready in July."
Woot. I thought 70s era systems were big.
Sheesh.
deleting the extra space after periods so i can stay relevant, yeah.
Aren't you the guy who was arguing with me a year or so ago about what a great plane this is, while I said it was a giant turd squeezed out onto the taxpayers of the USA and its clients?
The argument ended, if I recall correctly, when you vanished in the wake of a story that one of these pathetic trailer queens burned down to the landing gear while sitting on a runway, and they had to ground the whole fleet.
I've calculated my velocity with such exquisite precision that I have no idea where I am.
These F-35 FUD writers are getting desperate.
They call it the "brains" of the plane. It isn't. The brains are the sensor fusion computers. This is the Autonomic Logistics Information System. Key word: Logistics. It's a maintenance system. They say the whole program is a failure because the fancy maintenance system could ground the fleet. Except most of the USAF flies just fine without this type of system. Oh, and the problem isn't that it doesn't work, it is working. It's that it hasn't been thoroughly tested. Why? Because it's still in testing. Then they complain that there is no backup system if it doesn't work.
So they cry that the program is too expensive. Then cry some more because there is no redundant replacement for a non-critical system. Of course if there were a backup system they would be complaining that the program spent millions on duplicated efforts. It's just stupid.
