back to article Software troubles delay F-35 fighter jet deliveries ... again

Deliveries of Lockheed Martin's F-35 fighter jets to the US military are being delayed again and despite all the metal, software is the culprit.  Lockheed held its fourth quarter earnings call yesterday, with president and CEO Jim Taiclet blaming the delays on software associated with Technology Refresh 3 (TR-3), a key …

          As defense systems have become more coplex and expensive, governments have been forced to abandon traditional procurement approaches, such as developing competing designs to the point where they can be tested and evaluated. But by selecting and relying on one proposal, they leave themselves without any fall-back choices and can only move forward in the hope that things will get sorted out. And the vendors know this - one implication being that having a successful paper proposal is more important than actually being able to deliver on their promises. In fact, as long as things don't get to the point where they are obviously hopeless, the vendor stands to benefit from poor performance.

            "as long as things don't get to the point where they are obviously hopeless"

            Sometimes seems that things do get that far!

            I agree that the cost of building such planes and other large bits of military hardware is far beyond the scale where a company could build a couple of prototypes on the hope they will get picked. If you go back to the power WW2 era the various US and even UK aircraft manufacturers were turning out planes without any pre-orders.

            Having worked on DoD projects I always got the feeling that the specs were made by the higher ups with little or no input from those who would actually be using the thing. The new US air tanker is a classic where the refuelling boom operator has to work via a camera rather than a window and the camera is B&W, can't cope with glare, has a poor dynamic range, poor depth perception (it is 3D with a set of special goggles to view the screen) and generally rather crap. Thankfully the cost of replacement with a better colour system is being taken on by the supplier and not the US govt. You'd think this would be a system they'd test endlessly on an older tanker before building the new ones.

          The USN's lost what balls it had back in the day, when it took over Brewster Aeronautical Corps

          and shuttered it in the end.

          But of course, if the USN were to take over Lockheed-(whatever), it'd face a massive turf fight with the USM and the USAF over how to best mismanage the manufacturer, in a manner befitting the current best practices mismanagement guide/s Lockheed is currently using.

        No car on the planet gets the TLC that any aircraft gets in its' lifetime [with the exception of F!, NASCAR etc] , and I can tell you from experience that an F-35 gets an incredible amount of maintenance for each flying hour.

            What air force? The non-existent air force that we refuse to help replenish despite blood promises to do so that they're using to wipe the floor with Russia anyway?

            By the end of the first year of the war, Ukraine's air force as considerably bigger than what they started the war with. Mostly with lots of spare parts, and quite a few spare jets, from Eastern Europe. That allowed Ukraine to re-activate some of their own old jets, as well as keep others going - and then there were a decent number of, I think, Polish and Slovak ones as well.

            What we didn't do, was plan for a long war. That Ukraine would have to transition away from any complex kit that needs spares or ammo provided by Russia. It's easy enough to make Russian calibre 152mm artillery shells - but not so easy to get reloads for S300 surface-to-air missile systems or air-to-air missiles compatible with old Soviet fighters.

            There's been a lot "MacGyver-ing" going on though. Storm Shadow cruise missiles and HARM anti-radar missiles onto the SU24. But only the older stuff, without the modern ability to transmit mid-course guidance and target changes.

            Given some of Ukraine's recent successes - I do wonder if we've bodged some decent long-range air-to-air solution? Or have they just sneaked Patriot batteries right up to the front lines, for a brief few long-range kills, before moving them back to safety again?

            There's also a Franken-SAM project, to get Western missiles onto the old Soviet launchers Ukraine has. Because NATO is mostly pretty poorly provided with SAMs - relying on getting air superiority instead. So the US have managed to get Sea Sparrow onto Ukrainian Buk mobile short range SAM launchers. The UK have built a mobile launcher from scratch to fire ASRAAM - and US are doing something similar with Sidewinder - so a radar launcher truck firing an air-launched infra-red missile.

            F-16 is on the way now. Too late, like everything else. But I don't think the politicians were really wanting to believe in a years long war. Bit like the start really, where most people refused to believe Russia would do something so stupid, and so disbelieved US and UK warnings - despite the massive (and un-precendented) mobilisation of Russian forces. Similarly I just don't think politicians could believe that Russia would do something as stupid as to keep the war going for two years, when it was clear from week 4 that they'd already lost.

          The Russians haven't been able to obtain air superiority over the actual battlefield, despite having more and newer aircraft.

      Re: The F-35 engine

      I thought they'd already released the engine upgrades, last year. Although it's actually an upgrade to the engines electrical generators.

      There's also a plan to upgrade the engines in future, but that's a different thing. To both give more whoosh and more electrical power.

      Modern Western planners seem to be wanting to add huge amounts of power generation to both their ships and aircraft. Partly in hopes of future laser weapons. But also because modern radars can also be used for offensive electronic warfare. Which is horribly power-hungry. Plus if electronic warfare is more prevalent, you need more power to your radars to burn through it.

      The problem is that the older the aircraft, the more of these upgrades you're going to have to retrofit to get up to Block 4, hence the more expensive.

          Re: The F-35 engine

          You're thinking of an AM radio broadcast antenna. These aircraft don't use that. Easy to confuse. And to save you the typing, just because it has Active in the name, doesn't mean that it's a sonar ping that everyone can detect and get a fix on. That's kinda the point. A short extremely directional scan here, another one on a different frequency there (all of the components able to do something different all at once) and it's stupidly hard to detect or even understand what you are seeing if you do. There are also other advantages that if put to use means that somehow the stealth factor has already been obviated so turn it all the way up and start cooking things.

    Magnificent men in flying machine

    Don't the Chinese already have working software on their version of the F-35?

    1. I ain't Spartacus Gold badge

      Re: Magnificent men in flying machine

      It's impossible to know. They're not telling, because they have no democratic oversight.

      I've seen suggestions that their engines are incredibly under-powered - but again, it's hard to know because the people in the West who might know aren't telling. And that's assuming they do know.

      However it idiotic to assume that if they want to create systems this complicated they won't also have these kinds of problems. So if they're not having software problems, it's probably because their software is pretty basic and not capable of all the shiny things F-35 can do when it's working properly.

      Clearly the F-35 software is a mares nest though. It clearly needs to be more modular, so it can be upgraded in little bits, rather than massive upgrades of everything all at once. Hopefully a lesson that can be slowly retro-fitted to F-35 and kept in mind with new programs like GCAP.

      If you look at the "spiral development" model in missiles that the European defence industry has got going now, it's deeply impressive. With continuous, incremental upgrades to systems that are also cheaper becausue they often have common parts. It's also often true of Navies. We need some of this in our aircraft industry. The days of an aircraft being scrapped after 15 years are long gone, and types seem to hang around for decades now. There are B-52s built in the early 70s (when I was also built) that are planned to still be flying in the 2070s - after I've been scrapped... Rolls Royce are building them new engines at the moment. They'll probably be on their umpteenth set of avionics and electronics already.

      1. Wellyboot Silver badge

        Re: Magnificent men in flying machine

        The big problem with F35 is that it was planned to replace both mainstream jets as well as niche specialist roles and supply state of the art stealth in a single type in large numbers to offset multiple sets of development costs (political meddling anyone). Unfortunately the only useful mission overlap between the older aircraft is that they drop bombs, The A10/F16/F117 fly home to nice big airfield (USAF), the F18/A6 fly home to a carrier (USN & USMC) and Harriers fly home to where the USMC have built a temporary airfield behind the front line (mud marines really like having Harrier support nearby, the A10 can also operate from roads but the USAF like their comfort).

        It comes as no real surprise to many aircraft engineering types that the F35 being (mostly) superior to all older types actually needs two different sets of wings and two different fuselage designs to do this. The Navy model (F35C) has much bigger wings to allow carrier operations and the VSTOL (F35B) has a completely different fuselage (both compared to the F35A Air force version), but they are all the same from the pilot forward and share avionics.

        The upshot is that the Swiss army knife of aircraft will cost far more overall & take longer to develop than the set of assorted blades it’s meant to replace.

          They designed three variants, for three different branches, claiming SYNERGIES. Last I heard about 30% of components are common to all three. The design of the plane is a long list of compromises. As in let's compromise the mission!

        >They're not telling, because they have no democratic oversight.

        Like all advanced weapon systems the details (good and bad) are secret. So even with our 'democratic oversight' -- aka "Congressional committees sniping at contractors because of cost overruns" the real details are only going to be known to a carefully vetted set of insiders.

        I don't know where the money goes but given that massive cost overruns and schedule slips are the norm, not the exception, I'd guess its just business as usual. But since these planes are primarily going to be used to attack weaker neighbors, preferably ones who can't easily shoot back (or retaliate), then their actual performance isn't that important.

      In fairness to the F-35 (ugh, I can't believe I typed that), the requirements heaped upon it are somewhat mind-boggling and recall the spoof MoD document calling for flying unicorns in Charles Stross's novela "Equoid." The F-35 is required to have variants which:

      * Can provide air interception

      * Can provide close air support

      * Can land on aircraft carriers

      * Have STOVL capability

      * Are stealthy

      * Are supersonic

      * Have super advanced avionics and flight control systems

      * Have giant fairy wings and embody the magic of friendship (okay, this one I made up)

      No it isn't. F-35As are down to somewhere below $80m each nowadays. That's less than a Typhoon and similar money (or less than) a SAAB Gripen.

      Now the F-35 has massively higher maintenance costs, and is still a new system - so if you buy one this year, you'll need to fork out to upgrade the computers and the software to Block 4. And if you bought one before last year, you also need to fork out for upgrades to the electrical generators in the engines and various other bits.

      But they're also stealthy and have massive advantages in "sensor fusion" and communications and intelligence gathering. Which is why they're probably best used in a mix with other aircraft.

      Everything's secret. So it's impossible to know how good they really are. However F-35 has won all the recent competitions against F/A-18 Super-Hornet, Typhoon, Rafale and Gripen. That ought to say quite a lot. The only countries who could afford it that haven't bought it, either weren't allowed to or were making rival products. Even there, Germany, Italy and the UK have bought a mix of Eurofighter and F-35.

    For real though, anyone who's paid more than surface attention to the F-35 program has to realize that it's fantastic value.

    Sure, it's fun to break out the total lifetime program cost, and divide it by number of airframes and pretend each airframe costs that.
