Ada was proven to work. Why should they take something that they know works and replace it with something they know is worse? It doesn't make any sense to me. If they wanted to test out a new language like Rust or Go and it was worse, that's one thing, but they know C++ sucks. Everyone knows C++ sucks.

This is the UNIX "it doesn't matter" mantra all over again. "Doesn't matter" always means "sucks". When someone selling a car says "gas mileage doesn't matter" they're saying "the car's gas mileage sucks." Programming languages matter. If someone trying to get you to use a programming language says it doesn't matter, the language sucks.

>The F-35’s core software is written in C++ and runs on commercial off-the-shelf PowerPC architecture processors.

C++ is worse than Ada, but it's also worse than the languages that were previously used in flight software. If the programmers aren't smart enough or just don't care enough to learn Ada, Fortran, Cobol, or whatever, they shouldn't be working on this sort of thing anyway.

>Memory devices too slow, mission data software delayed

Are the memory devices too slow or does the software just suck? If they're using XML or some UNIX-inspired text bullshit, their memory won't go as far.

Why am I retraining myself in Ada?  Because since 1979 I
have been trying to write reliable code in C. (Definition:
reliable code never gives wrong answers without an explicit
apology.) Trying and failing. I have been frustrated to
the screaming point by trying to write code that could
survive (some) run-time errors in other people's code linked
with it. I'd look wistfully at BSD's three-argument signal
handlers, which at least offered the possibility of provide
hardware specific recovery code in #ifdefs, but grit my
teeth and struggle on having to write code that would work
in System V as well.

There are times when I feel that clocks are running faster
but the calendar is running backwards. My first serious
programming was done in Burroughs B6700 Extended Algol. I
got used to the idea that if the hardware can't give you the
right answer, it complains, and your ON OVERFLOW statement
has a chance to do something else. That saved my bacon more
than once.

When I met C, it was obviously pathetic compared with the
_real_ languages I'd used, but heck, it ran on a 16-bit
machine, and it was better than 'as'. When the VAX came
out, I was very pleased: "the interrupt on integer overflow
bit is _just_ what I want". Then I was very disappointed:
"the wretched C system _has_ a signal for integer overflow
but makes sure it never happens even when it ought to".

It would be a good thing if hardware designers would
remember that the ANSI C standard provides _two_ forms of
"integer" arithmetic: 'unsigned' arithmetic which must wrap
around, and 'signed' arithmetic which MAY TRAP (or wrap, or
make demons fly out of your nose). "Portable C
programmers", know that they CANNOT rely on integer
arithmetic _not_ trapping, and they know (if they have done
their homework) that there are commercially significant
machines where C integer overflow _is_ trapped, so they
would rather the Alpha trapped so that they could use the
Alpha as a porting base.

By not getting rid of reliable software that works by replacing it with unstable software with a billion useless features and then paying some contractors millions of dollars to ll contractors to make it.

My mother is a fed and they are doing this at her work, and they wonder why they are over budget. They literally dumb down the software she has to use so it can be ran on a smart phone. Why would you want to do that? The team behind are so soykaf that they can't even sort records in a way that's not alphabetical or numerical. I could implement that in less that 5 minutes. In fact, I could probably make the whole piece of software myself both faster and cheaper.

While it's a government contract that, therefore, does not have professional pajeets, all of the engineers aspire to be professional pajeets. By using sepples, the contractors are growing job skills using a language that is prevalent in industry. Of course, it is prevalent in industry because companies want to use a language that makes their local programmers fungible with pajeets, as pajeets are cheaper. The contractors view using sepples as career growth. There is also the ability to use sexy new technology: many open source projects use C or sepples, and using sepples makes integrating those projects into the code easier. Why should government contractors rewrite X in Ada, when X is an open-source C project? Who is going to maintain that Ada version?

I would talk to some Swedes for starters. The Gripen program runs at a fraction of the cost of the JSF, about 1/30 I think.

They integrate parts like radar from lots of different suppliers without much problem.

IIRC some engineer had the bright idea to make the software modular (I think the used "apps" to sell it to management). The company trusted the engineers and now they are doing pretty well.

As for the JSF, that is working as intended, since it's main purposes are to defraud taxpayers across the world and cripple air forces while doing so.

There are four problems with the F-35 program:

1. Too much stress is placed on one company, which can't do everything itself.

2. Too many missions for one platform. F-35 is supposed to replace: F-15E, F-16, F-18, A-6, A-10... and dozens of other aircraft in other services.

3. It is introducing too many new concepts into a single airframe, including automated maintenance for fucks sake. Every aircraft designer worth his salt knows more than half of any new design has to be grounded in battle tested components, techniques, concepts...

4. It costs too much. As it is, in the present state, it should cost about $40 million. It doesn't have a functional gun, half the software is nonfunctional, the headset is nonfunctional, it can't fly above certain altitudes.... It costs $130 million, that's the cost of a frigate.

Easiest solution is delegation:

1. Let northrop grumman build a twin engine air superiority fighter F-25 for air force, RCS of 0.01m2

2. Let mcdonnell douglass build a twin engine multirole catobar F-30, RCS of 0.0005m2

3. Let lockheed martin work with mcdonnell douglass to build a single engine VTOL F-35 version for marines, RCS of 1m2

4. Let lockheed martin build a single engine multirole F-35 version for air force, RCS of 0.01m2

No it isn't, there's roughly same amount of fuel consumption.

Except the difference is that in Yak-141 the thrust is heated evenly, front thrust is sort of warm, and rear thrust is sort of warm, but neither is too hot. Whereas F-35 front thruster is 100% cold, it's literally a helicopter in the front, a ducted fan. Yet due to thermodynamics the rear jet is twice as hot, because all of the front fan's heat is still there, it's just being spewed by the rear jet.

End result? F-35B rear thruster is so hot it bores holes in aircraft carrier decks, so they needed to install ceramic heat absorbing pads from fucking SPACE SHUTTLE on every LHD where F-35 is supposed to land.

I know I'm just an armchair poster but if I could fix the F-35 program I'd do the following:

- completely scrap F-35B STOVL, if you want to hover use helos

- simplify F-35: scrap fancy helmet and scrap 360 deg view cameras

- redesign underside to be flat and able to hold more ordnance (8x AMRAAM would be nice)

- give it a strong forward looking IRST mostly for A2G

- give it more ammo for the gun

- rewrite all its software in Ada

- change wing config to delta like Mirage 2000 for extra fuel and increased loadout, because its handling is shit anyway might as well sacrifice it further (or hell, even YF-23 diamond config like pic related would be sexy)

That pic about Sanders is somewhat misleading. He hasn't pushed funding for the overall JSF program, and has actually castigated it as exceptionally wasteful on numerous occasions. Rather, Sanders merely says that while the juggernaut of the program rolls onward, requiring contractors to be built by and bases to be stationed at, that they be in Vermont rather than elsewhere.

If you scrap the helmet, you are going to have to make changes to the canopy to give better rearward vision. E.g. the mig 15s in the korean war were arguably better than the sabres but the sabres had better rearward vis so waxed some korean tail. With all these changes it is pretty much a shit f-22.

>With all these changes it is pretty much a shit f-22.

Exactly! Which is exactly what it was always meant to be, the faggometric STOVL meme notwithstanding: a smaller, cheaper, single engine, "multirole" version of the F-22, basically a shit F-22 that could be exported to the "allies".

A crappy little F-22 fully capable of destroying SAMs, helicopters, convoys and some buildings after the F-22 killed all enemy fighters. I mean the F-35 still is all those things but for a stupid high price tag. For its own good it needs to be simplified and cheapened, and I don't think this is a controversial opinion.

>If you scrap the helmet, you are going to have to make changes to the canopy to give better rearward vision.

IMHO this would only be a problem for the STOVL version, which would be scrapped anyway. I do admit the helmet looks pretty cool, but the F-22 deserves it more. F-22-MLU anyone? Might as well put all that hard-earned money to good use, Lockheed.

The thing that upsets me the most about the F-35 is the fact it is entirely reliant on stealth tech, the only card it has to play is that russia and china don't have the same stealth tech yet.

LOL, you carry more parts in your plane and you expect it to have the same efficiency? Why do you think Yak41 has 30% more volume than the F35 for the same range and half of the payload?

Also, the engine is not hot due to the fan, the fan might interfere in the consumption but not the exhaust temperature which is determined mainly by the compressor, the temperature of the exhaust is high even in F35A.

The exhaust is hot due to the supercruise capability, to achieve that the engine works at a higher compression rate and temperature as well as higher bypass. It doens't help either that it needs a larger thrust (diameter) due to the fat aerodynamic, which is a result of it's steath capability, increasing the surface area affected by the exhaust.

>>902848

>LOL, you carry more parts in your plane and you expect it to have the same efficiency?

I'm going to go with Yak 141 being more efficient.

Yak 141 has a range of 2100km, F-35 has a range of 1700km.

F-35 has 6 tonnes internal fuel, Yak-141 has 4 tonnes internal fuel.

Per ton of fuel Yak 141 is traveling 525km while F-35 is traveling 283km, 1.85:1

F-35 engines are 30 years newer, so it isn't the power plants problem. The reason for Yak being almost 2x more efficient is entirely due to aerodynamics!

By the way a newer version of the Yak plane with more modern engines and 6t fuel called Yak-201, has a range of 4300km.

>Also, the engine is not hot due to the fan, the fan might interfere in the consumption but not the exhaust temperature which is determined mainly by the compressor, the temperature of the exhaust is high even in F35A.

Do you not know how thermodynamics works? To convert the chemical energy of fuel into work requires to burn it, which has waste heat.

In Yak-141 two separate engines are burning fuel, for two separate thrusters, ergo their waste heat per unit thrust is separated into two as well.

In F-35 one single engine is burning fuel, for two separate thrusters, ergo the heat per unit thrust is focused on a single exhaust.

Lockheed being full of engineers like you is whats causing your problem.

Exact opposite problem in the case of the MIC, it's military officers (especially generals/admirals) "retiring" into the boards of contractors, getting "consultant" gigs with contractors, and even straight-up kickbacks from contractors. Simplest fix aside from massively slashing post-Cold War military spending from $1.3T/year to something saner for nuclear deterrence and multilateral peacekeeping like $400B/year is to ban the revolving door between military and contractors, as well as eliminating no-bid contracts.

It's supposed to be a generation ahead of F-16, that generally means being better. It's not better. F-35 is slower, less agile, it has a shittier radar, no cannon, and carries fewer weapons. In performance terms it is equivalent to a F-101 or F-102, which are from the 1950s. The sensors are similar in coverage, range and power to what was fielded in 1978.

The stealth is inferior to F-117, which was a jet designed in the 1980, shot down over Serbia in the '90s using missiles from the '60s. This was back when no one knew anything about stealth and it was still a huge paradigm shift. World has had 30 years to get used to stealth, find techniques to defeat it, and put weapons in service that can counter it.

Bottom line:

F-35 performance is 60 years out of date.

F-35 sensors are 40 years out of date

F-35 stealth is 35 years out of date

The fact that its wrapped into a cool looking wrapper is beside the point.

>>903603

Yeah except that's a strawman, this isn't what I said

>the more fuel you add, the higher the temperature of the combustion/exhaust

The more energy you generate per engine, the higher the temperature should be. A Yak rear engine is only generating enough thrust to lift the rear section, two smaller engines lift the front part of the aircraft. A F-35's single engine is generating enough thrust to lift the entire aircraft. Ergo the exhaust temperature is focused. Here I drew a diagram for you.

It's not a strawman, you simply haven't understood what you were implying and is still making the same mistake in your explanation.

Energy and temperature are not the same thing, the more energy generated doesn't necessarily means the temperature is higher.

If you burn 1 centillion tons of paper in a huge campfire, you will produce tremendous energy that will spread heat across the whole planet's atmosphere for hundreds of years but it won't get hotter and hotter until you have a campfire hotter than the sun, you'll simply get a huge fire at 451F, which is the burning point of paper, it can't burn hotter than it's own burning point and heat transfer can only happen from hot to cold so there's nowhere in that campfire that could get any hotter than 451F.

For something to burn what matters is the temperature. No matter how much energy you throw at something, it can only burn if it reaches it's burning temperature and to do that it needs something at a higher temperature to transfer heat to it.

The F35 burns things because it's exhaust it's hotter, it's not the amount of fuel, it's not amount of the energy generated by the engine, it's not the position of the engine, it's simply the temperature.

Let me give you an example, a GE9X turbofan of 400kN burns a tremendous amount of fuel and generates an outstanding amount of energy yet you could stand at some yards away from it's exhaust and not be burned alive, which is what would happen if you did the same to a J85 turbojet with just 15kN.

>Energy and temperature are not the same thing, the more energy generated doesn't necessarily means the temperature is higher.

Nigger we didn't invent a 225% more effective way to burn hydrocarbons for the F-35. Both R-79V-300 and P&W F135 are turbofans with six compressor stages. Both burn jet fuel with relatively same properties.

J85 is a turbojet, a different type of engine, with 8 compressor stages, which causes insane heat concentration. GE9X has only two compressor stages which is why it is cooler, and it's a high bypass turbofan which differs wildly from a low bypass turbofan.

You know fuck all about jet engines and what is causing the problem in F135.
