    I am very aware of the dangers of "live steam"... however, a pipe is easier to repair than god knows what kind of electromagnetic whatever the fuck they embed under the decks.

    Something that I don't think a lot of people get about naval ships is that most of the maintenance happens at sea. They only send the ship in to a yard or dry dock if they have to and they try to limit what a ship goes into a dock for to things that can only be done in a dock.

    A steam catapult is much more likely to be repairable at sea than is an electromagnetic catapult. It will be easier to diagnose problems and easier to patch.

    What is more... I want you to think of most heavy industrial machinery. Most of it is driven with hydraulics and pneumatics.

    Also I'll just point out that in your case you're talking about exposed high voltage lines... which could be exposed to salt water on the decks... oh and the whole thing is fed by two nuclear reactors.

    I think you underestimate that bug zapper quality of the thing you're defending.

    I'll take my chances with live steam, thanks.

    The nature of the piston is more configurable than that.

    You can have multiple inlets for steam that trigger as the piston goes forward, thus causing an increase in the amount of steam as the piston expands. If configured properly, the stroke can be as uniform in force as anyone will notice.

    You'd probably be surprised what you can do with mechanical parts.

    keep in mind that the Apollo rockets were mostly mechanical. A lot of the things in them that we'd do today with mirco controllers, they did with valves and pressure regulators and such.

    There are advantages to doing it either way.

    The digital method is typically easier to set up and easier to configure if something needs to be calibrated.

    However, the more robust systems tend to be easier to maintain and harder to damage.

    In both military and industrial settings, you use a mixture of both systems. Things that need to be tweaked a lot are typically digital and electronic. Things that need to be really strong and really tough tend to be hydraulic or pneumatic.

    I'm not sure if their main boiler runs entirely on that. They could and recycle filtered water.

    However, when there were the big typhoons in east Asia that caused something of a survival problem for millions of people, the US dispatched a couple of its carriers to the region to provide clean drinking water.

    The carriers can produce huge amounts of clean drinking water and I believe they do have large desalination plants inside of them. Whether they must be used for the reactor or not is not known to me. But I do know they do have a significant desalination feature in those carriers. More than enough to supply steam to the catapult without thinking about it.

    Again, all nuclear reactors that we've ever designed work on the same principle that the old external combustion engines worked on... you have a boiler which is heated by some means... in this case it is heated with a reactor. And that heat is used to boil water, which creates pressure, which then is either fed into pistons or turbines to generate power.

    That is how they all work.

    So the reactor is boiling water. How pure that water is... is not known to me. I'd have to look at the schematics or do some research to figure that out.

    It doesn't matter though in this context because we're just talking about enough steam to drive the catapult. And really if you wanted to, you could recycle 100 percent of the water from that operation by having it expand into some expansion chamber rather than just venting. However, I don't see why anyone would care. The water loss is not going to be relevant to a nuclear carrier on the ocean. The damn thing can desalinate as much water as it wants.

    The problem with your argument is that perfect security in computers is actually possible... theoretically. Perfect defense in conventional military terms is not even theoretically possible.

    You control too many things in a network for the two situations to be analogous. They can't attack you unless they get into physical proximity of your systems or intrude through your firewalls.

    That's already a huge advantage. Think of that in terms of military defense.

    Imagine if the enemy could only attack you through one little mountain pass and no where else. All you have to cover was THAT entry way.

    Then consider you don't need to let just any jackoff through the pass. Instead, you can block anyone from entry except those you've determined to be authorized.

    Intrusions are thus a matter of determining who is authorized and who is not through your gate.

    There is no question of your supremacy at your gate. You can't be credibly assaulted.

    A hacker is more like a smuggler than an invading army.

    Now if we think of this like smuggling... can that be stopped?

    Well, they can only enter through that gate. They can't sneak in anywhere else unless your organization is far more incompetent than we need to worry about in this thought experiment.

    So how do you keep out or detect 100 percent of smugglers?

    1. You control the protocol of entry such that no one can enter unless they're very familiar with the system. Secret handshakes and the like. An insider could out your systems but unless they have that they'll reveal themselves.

    2. You segregate the data flows into types. This type of data goes here. This type of data goes there. Smugglers tend to get through by mislabeling things. This bag full of drugs is relabeled as coffee. But if you make it impossible for the box labeled coffee to go anywhere but the coffee warehouse than you restrict the distribution of the drugs once they get past the front gate.

    The point is if you set up your firewall rules properly it will be very hard for anyone to do anything. High security systems for example shouldn't be conducting all affairs over VPNs. This means someone trying to access the system without the codes and encryption for the VPN can't talk to that system at all. That is the secret handshake.

    Have we seen any of these systems get their VPNs breached? Nope. The systems breached weren't using VPNs.

    to say that we can't secure systems because bad security policies or absent security policies get breached is silly.

    You lock it down and they're not getting in.

    I could go through a long list of protocols that could be followed that would make these systems 100 percent hack proof.

    No. 100 percent. NSA proof. FSB proof. No one is getting in.

    The only thing I couldn't stop would be guys showing up to the data center with guns and shooting their way in. That is a security situation for someone else.

    But if your concern is keeping hackers out? 100 percent security is possible. Not 99.9. 100.

    The carriers are all nuclear which means they boil sea water to turn steam turbines.

    That means they have lots of steam. Stupid amounts of steam. Always.

    The EM system means you have high voltage lines running under the decks and I generally think the system is going to be more complicated and harder to repair/maintain than the steam version.

    Smoother acceleration? That also makes no sense. You can make a steam piston VERY smooth. As smooth as an electromagnetic whatever?... probably not but who cares... you won't be able to tell the difference. A machine measuring it might be able to tell. But a difference small enough that the dude getting thrown by the thing wouldn't notice is unlikely to be relevant to the airframe.

    I am all for using superior technology. I just think there is a bias sometimes to go with electronics on the assumption that they're always superior. Sometimes they're not. Pneumatics or hydraulics or steam in this case are contextually superior in given circumstances.

    We were hearing about them testing robots to go into a nuclear reactor in Japan. The robots all have complicated electronics and micro controllers. That's been shown repeatedly to not work. They radiation destroys the micro controllers.

    When it comes to big machines that push heavy things around, you find that such big industrial machines are hydraulic in most cases. They rely on pressure. There is a centralized compressor somewhere that drives pressure through tubes and pipes... and that pressure is controlled to move heavy stuff around.

    So here you have this big carrier with I believe two nuclear reactors in it... generating fuck tons of steam... and you're going to draw on the electrical grid of the ship instead of just drawing on the boiler directly?

    Why? I'm just not seeing it especially in a battle platform.

    What you want in a battle platform is something as robust and reliable as possible. A steam piston is more reliable than some electro magnetic whatever. That catapult goes down and the carrier is useless. Think about that. That is easily one of the most critical components of the entire carrier. Right up there with the flat deck on top in so far as utility. No catapult and most of the planes can't take off at all.

    Saying that you can't do this with finesse ignores that the most advanced robots these days actually make use of pneumatic actuators.

    I speak of public universities only. Private universities and corporations can do whatever they want. But if you're taking the public coin then the public has a right to insist on integrity. What private individuals want to do with their own money is their own business.

    Simply cutting the sophists off from public funding should largely solve the problem. That is where this fungus has grown. The corporations are too goal oriented to get side tracked by this sort of thing.

    The whole TPS report thing from office space was a consequence of someone that doesn't know how to code or understand the product trying to keep tabs on people that were creating that product or service.

    So they create artificial benchmarks and paper work and then judge the employees by how well they comply with the paperwork.

    The problem is that the paperwork is not actually anything the customer cares about. It has nothing to do with the product or service. It is an arbitrary management mechanism. And it is FINE if the manager doesn't need it. If the manager can judge your work without it, than the paperwork might make his job easier.

    What is more, every design decision has to be checked with every god damn branch of the military because they're all basically using a very similar platform.

    The F35 should have been like... five or six different planes. Each with their own design considerations, life expectancy in the fleet, and supply chain.

    The marines wanted something like the harrier jump jet. Boeing had something like that ready to go for a fraction of what the F35 cost. Give them that.

    The army doesn't care about vertical take off or landing. They're happy to build an airfield so long as it doesn't have to be perfect. They like big cargo planes and big bombers... so they're going to have access to big airfields. The army likes firepower where as the Marines prefer flexibility and some nimbleness.

    The Navy is all about pessimism and preparing for the worst. They like things to have back ups and back ups of back ups. And fail safes when the back ups fail. So they like their planes to have two engines for example. Because they don't trust that one of those engines might die for no reason and cause the plane to go into the drink. They also like range. That lets the carriers stay back and well out of harm's way. Vertical take off and landing are not required when you have Nimitz Class super carriers.

    And the airforce likes to paint shit black and go veroom veroom. Seriously though, they like speed, stealth, and fighters that turn on a literal dime. The number of engines, how much fire power it has, or whether it can land vertically isn't really important to them.

    Trying to combine all these objectives into a single airframe was dumb. And that's why the F35 was a disappointment.

    And to make matters worse, the F22 is absurdly expensive which is driving us to replace its role as much as possible with drones. That is our goal there. The F22 might be relegated to a forward drone commander. All that maneuverability will be pointless.
