> One solution favored by Winter during his recent tenure was so-called agile software development. His vision for “continuous capability development and delivery” resembles DevOps, a popular method in the private sector for quickly testing and evaluating features for new products. Coders generate software upgrades or patches in a matter of days or weeks, pass them along to users to test and then push out the update more widely if the changes are successful.

Are the rest of the details of the article, about domains I don't personally understand, equally subtly inaccurate and misleading?

"Are the rest of the details of the article, about domains I don't personally understand, equally subtly inaccurate and misleading?"

I think that's the case for most things where people who are not complete subject matter experts write about something. A lot of our own conversations about things are probably quite inaccurate in a lot of details.

In this particular case the author may even have asked back but what is the author going to do if he/she gets fed inaccurate information? I think the only blatant inaccuracy is the reference to DevOps, otherwise the description of agile is pretty OK too me.

I hope people won't fall into the usual trap where some inaccuracies in some media leads them into reading much less accurate but more extreme media which is something you often see in politics.

Is it really that bad for a general readership? I'd like to see automated testing in there. And maybe incrementally improving products. But to someone who doesn't know and doesn't care about the details of software development, it seems to capture the basic gist.
danso 186 days ago [-]
Putting aside the accuracy of the NYT's definition, what's confusing to me is...why even mention "DevOps" in the first place, as if it were relevant elsewhere in the story, or as if it were something the general readership would know enough about to use as a point of reference (which I'm assuming they don't)?

Remove the reference to "DevOps", and you have a concise enough explanation of "so-called agile software development" and a cleaner paragraph overall:

> One solution favored by Winter during his recent tenure was agile development, a popular software engineering methodology used for quickly testing and evaluating features for new products.

(Since software teams in the U.S. government, such as 18F, also use agile dev these days, so it's not particularly relevant to point out its popularity in the "private sector")

ghaff 186 days ago [-]
Good point. As you suggest, the definition may or may not be "OK" but it certainly doesn't get into anything around how DevOps might be different from or go beyond agile. For a NYT audience, that's a pretty decent quick definition.

The article describes at length the thoughts of Lt. General Christopher Bogdan, who was in charge in 2014; Vice Admiral Mat Winter, who was in charge until this past July.

"Dysfunctional" is also misleading. The program has produced three operational variants, including the first ever supersonic STOVL aircraft. The US and Israel have both conducted F-35 airstrikes. That is a called a "functional" (if by no means perfect) aircraft development program.

It's also encouraging to see the F-35A price falling as expected...

The comment you point out reminds me of something Margaret Hamilton said:

Also, what became apparent with Apollo – though it is not how it worked – is that it is better to define your system up front to minimise errors, rather than producing a bunch of code that then has to be corrected with patches on patches.

So, in other words, it is better to do waterfall development?

Indeed, it sometimes probably is, and agile generally shouldn't mean you just make it up as you go along. But I think we've generally come to recognize that, at least in many cases, being more flexible and iterative.

This, to be clear, is not in any way a knock on the many people who developed software for Apollo. It was a type of project and set of technologies that made it difficult to be as iterative as, certainly, pure software projects are today.

mmmBacon 186 days ago [-]
I think her comment is specifically around software that is critical for human life support. She is advocating for design in such cases. I posted it because I would consider the SW for the F-35 to be in this category.

It’s worth questioning whether agile SW development that we do for websites, apps, etc... is good when human life hangs on the line.

TheOtherHobbes 186 days ago [-]
Clearly, there was never going to be any way to patch the Apollo Guidance Computer in the middle of a mission. Even if that weren't true, the development cycle was so long that iterative development was never a realistic option.

I suspect a project like the F-35 is a hybrid, with elements that are life-or-death mission critical and absolutely need to Just Work, and elements that allow for refinement - even refinement-by-failure in some cases.

Which just underlines how complex a project like this is. A distant descendant of the Apollo Guidance Computer code is likely just one of (at least) hundreds of equivalently complex routines and features in the F-35 codebase.

ghaff 186 days ago [-]

> There soon turned out to be an essential flaw in the grand plan for a single plane that could do everything. Design specifications demanded by one branch of the military would adversely impact the F-35’s performance in another area. “It turns out when you combine the requirements of the three services, what you end up with is the F-35, which is an aircraft that is in many ways suboptimal for what each of the services really want,” said Todd Harrison, an aerospace expert with the Center for Strategic and International Studies. “It is much more expensive than originally envisioned, and the three versions of the plane actually don’t have that much in common.”

And nobody was surprised.

I think the Navy and Air Force could have shared version with a lot in common. The Marines want VTOL and I understand that feature is important to the Marines. Unfortunately, the VTOL requirements have force compromises in the design. Without VTOL, I believe the Navy and Air Force would have ended up with a platform that was more acceptable then what they are getting.

I worked on the Comanche Helicopter program for a while, many years ago. The program was based on the same fundamental idea: create a helicopter that that could perform the roles of advanced armed reconnaissance and attack. The idea has a great deal of appeal. You could save on training pilots and maintenance crew. You could save on supply chain, and the cost of spare parts.

Unfortunately, coming up with a design that could effectively fill those roles was more than they could accomplish. Fortunately, the program was cancelled after spending ONLY $6.9 billion.

alkonaut 186 days ago [-]
The question isn’t whether the compromises are bad but whether 2 or 3 different programs with the same budget as this single program would have done better. That’s possible but not at all as clear as “the F-35 is expensive and technically a compromise between too many different goals”.
vikingcaffiene 186 days ago [-]
I've been following the development of this plane for a while now. I remember reading in a different article that the intention of this plane is to be a sort of everything to everyone type of thing. It's meant to replace a lot of other planes that are more fit to their specific purpose and has a ton of bells and whistles. Pilots hate it. I find that striking and it further validates some principles I've developed over the years. Namely, smaller units fit to purpose that compose together to make a larger whole will defeat a single unit designed to handle everything. It also validates that management cannot force a project to be successful no matter the stakes. At best you get a half assed final product delivered on time but untested and brittle.

An interesting angle which is underreported in my view is who is responsible for extremely expensive new military aircrafts: (former) pilots, who are now High-Ranking officers. No pilot has any interest in giving up flying and switching to drones/remote aircraft which are clearly the future. My bet would be that the first country which bets 100% on autonomous aircraft will probably be China, where there will be less opposition to such a move. The western countries will follow and the F35 will most likely be the last "big" non-autonomous program (excluding aircraft for special roles).

On an unrelated note: I submitted this article 4 days ago without any discussion [1], does anyone know what the time frame for resubmission on HN nowadays is?

The future is drones and so many in the air force know it. Not sure why they haven't bet fully on it. I guess there are no dog fighter drones yet but the first time a supermanuverable <10m drone destroys a 100m manned fighter well it is all over.
thunderbird120 186 days ago [-]
Supermanuverable <10m autonomous aircraft that have destroyed modern fighters already exist. They're called missiles.

Modern fighter aircraft are expensive because they are relatively large and crammed with tones of expensive avionics and sensors. Increasingly, the quality of your sensors and your ability to evade detection are more and more important while maneuverability is less important because of said missiles. Better sensors are larger and require more power to operate necessitating a larger aircraft. Also, the number of Gs an aircraft can pull is limited by both human survivability and airframe strength. This means as the size of the aircraft increases the max number of Gs it can pull will decrease. Missiles can pull 50 Gs. Even if you remove the human, no aircraft large enough to carry the necessary sensors, fuel, and weapons to be combat effective will reach even 1/3 of that because it would rip the wings off.

It's great to see this in the Fighter-Jet programmed mostly with C++, instead of Ada. I've read of rather queer flaws, such as that one mentioned involving the helmets. To its credit, C++ programmers are cheaper and more numerous, so you get what you pay for.

It seems 3 new separate aircraft would have been much better and cheaper.

It's true that the F35 seems a little beefy, compared to other aircrafts.

A single engine is quite bad for survivability.

While I can admit that vertical liftoff can be an asset if you want to respond quickly to an attack without building airstrips every 50km, it's hard to really justify building so many aircrafts with a airframe shape that allows VTOL. VTOL is a tough compromise on aircraft.

Having an aircraft that can play several roles is not a good idea. Regrouping roles is a good idea, but regrouping them all into only one is really not a good engineering decision.

That's like deciding to design a pen-lighter-laser-pointer-usb-drive-knife-screwdriver into a single device. It sounds cool, but in the end, it's better to see what can go together and what should not.

Unless the F35 has a next gen radar which allows it to see enemy aircrafts from farther, it will be bad at dogfights.

Car companies develop platforms on which they build many different models. For example in VW cars you can find exactly the same parts in Golf, Touran, Passat, Tiguan and many other models.

All these 3 separate plains probably could share 90% of parts, software, avionics, that VR helmet, etc. Having fewer constraints it would also simplify the plane body design.

Just image car engineers are asked to design one car to replace off-road, city and van cars. Even Elon Musk did not come up with that idea.

True (not as bad as it once was), but is a lot cheaper over the life of the program. They were trying to get a next generation F-16 to go with the next generation F-15 (the F-22), and that didn't happen.

From my research it looks like the same is true in civilian aviation. Statistically twin engines are more dangerous.

redis_mlc 185 days ago [-]
Single-engine fighters are ok for the Air Force, who fly high over land. Twins are preferred by the Navy and Marines, who either fly over water, or down low and get shot at, or both.

The civil link you provided refers to "light twins" (ie. underpowered and used in GA) used in training and EMS. Not applicable to airliners, which can safely take off on one engine.

Something to think about: all of my former twin instructors have been killed flying light twins.

Four-engine airliners are actually preferred for oceanic routes for safety, but regulators now allow twins (ETOPS), for cost reasons.

It's really not. To put it mildly, the report that that article draws from has been subject to some criticism over the years. To put it less mildly, if you link it in any community that follows military aviation closely they will probably make fun of you[1].

Performance is generally better than F-16s in real wold scenarios due to the more powerful F135 engine and the internal weapons bay which means carried weapons don't cause additional drag as they would if carried on pylons. That second point is extremely significant. The aerodynamic effects of hanging a bunch of stuff of your wings is pretty major, especially at supersonic speeds.

Here's a few pilots commenting on differences between the F35 and other aircraft they've flown[2].



TheOtherHobbes 186 days ago [-]
The enemy isn't a pilot flying something like an F-16, the enemy is a hypothetical low-cost high-maneuverability remotely controlled drone fighter which isn't limited by human tolerance for G-forces.

Or even a linked drone swarm.

On that basis, the F-35 will be obsolete against the other superpowers by around 2035 at the latest.

thunderbird120 186 days ago [-]
See my reply to the other person making that kind of claim

To expand upon that, manned aircraft aren't going away anytime soon because electronic warfare is a thing and until drones are capable of human level decision making you need a human in the loop. Drones will augment the F35's capability but against a near peer adversary you're going to need a manned aircraft at the center of every drone swarm. Especially if you're taking about small drones as those will be lacking the high powered radar which will be crucial in such engagements.

I’m not very familiar with the details of what’s needed tecnically for ”optionally manned”. Maybe it’s extremely complex and expensive. My guess would be that it’s not extremely complex or expensive.

And those fighters were never designed initially to be unmanned, that’s just a hack.
