> So, the enemy jams comms or shoots down satellites, and a F-35 squadron deployed to a base on the other side of the world can't do maintenance? This makes it sound as if ALIS does maintenance. ALIS does not do the maintenance. Human beings still do the maintenance.

From the article it seems like they need to drive around with ALIS CD-ROMs to do maintenance..

Well, obviously, ALIS is not a robot with mechanical arms that do the physical work (although with its name, it wouldn't be surprising if some people expected "Alice" to do just that; and the personification is creepily reminiscent of 2001: A Space Odyssey). But from what I've read in these articles and part of that GAO report, it sounds like ALIS is part of the designed maintenance protocols. For example, Action Requests are entered into ALIS and uploaded to the contractor (!) who triages them (!) and collates data across multiple sites (noted in the GAO report are problems such as a software update preventing contractors from receiving ARs while the on-site personnel are waiting for an answer--eventually they call and ask, hey, what about those ARs? and the contractors respond, what ARs? because they didn't know they were failing). And technical manuals are accessible through ALIS instead of having to refer to paper manuals. Of course, these are all so vague and general that it's hard for laymen to figure out what it would mean in practice. The terms used in the GAO report for expected functionality are so non-specific that it seems nearly useless to even use them. Having said all that, the GAO report does mention (buried in the middle of a paragraph, not prominently like a major vulnerability should be) that ALIS can be used in an offline capacity: > DOD officials told us that they recognize this issue and, for short-term losses of connection, ALIS users are able to work offline. (page 17) But that doesn't sound very reassuring to me. In wartime, all sorts of bad things happen, and lost connectivity and communications should be at the top of the list of expectations. If maintenance is severely degraded and aircraft can't fly sorties at the needed rate, well, in a war....

AIUI, every component of the plane has a unique identity and status. It sounded to me like this involves digital signatures and all that. So presumably, manual maintenance without the proper bookkeeping would be viewed as tampering/sabotage, and the plane would refuse to operate.

  > manual maintenance without the proper bookkeeping would be viewed as tampering/sabotage, and the plane would refuse to operate. If that's true, it sounds like a solution is search of a requirement. IIRC, but I don't think the US military has had problems with tampering and sabotage of military jets.

    Sounds more like DRM than prevention of sabotage. Like in printer ink heads... "Attention! Counterfeit hydraulics system installed. F-35 disabled until genuine system purchased". This would stop people buying cheap F-35 spare parts from China on ebay and trying to save a couple of million dollars.

  Interesting speculation, but General Bogdan's assertion that you can operate an individual F-35 for "up to 30 days" without ALIS indicates otherwise.
  - CWuestefeld 10y ago
    I don't think that contradicts my understanding. If no maintenance was necessary in the 30 day period, then there wouldn't be anything to detect.

      A droll reply would be, "It's a fighter, maintenance is always necessary." But to give a real answer: If a jet sits for 30 days without any maintenance, then it's supposed to be preserved. This means all fuel is offloaded, all lubricants drained and then refilled and then drained again (leaving a film of clean lubricant over important parts), etc. Otherwise, you have to perform an engine run to keep the aircraft nominally flyable. Really, if you aren't flying, you are either doing maintenance to prepare to fly, fixing something, performing scheduled inspections, or performing modifications. So if the aircraft is operational, there is no such thing as a 30 day period without maintenance. Without ALIS, you just do all of this via the old paper processes for a while.
