What makes this work "fun"?

Really hard engineering pushing the limits of physics and materials science is fun, killing people is not.

Do you genuinely see the same virtue in the engineering of a bridge and the engineering of a cruise missile?

I agree on at least the first half of your statement. Although I'm not sure I'd say 'delusional' as much as - I don't know? - Jingoistic? Bombastic? I feel like I should be playing Command and Conquer to that sound track. At the end of the day, these are killing machines that are being designed to take human lives, and it does feel more than a bit inappropriate.

A friend overlaid an EDM track (Flux Pavilion if I recall) on the original test fire videos from several years ago when the prototype was located at the Virginia test site. I enjoyed the short piece of creative they remixed in the same way I enjoyed the Iron Man franchise.

So it's fine to stockpile chemical weapons as long as we don't use them because they're just a tool?

I listened to it and agree it sounds very childish. Better would have been to have some intelligent narration, the story in a nutshell. How much energy is required for a railgun? What uses do they have that cannot be done with conventional artillery? what were some of the major challenges faced by the R&D team? All of that could have been explained in the audio track that was instead used for crappy Michael Bay actio…

One of the problems with existing Navy "gun ships" is that explosive ordinance can be a hazard to sailors and has to be handled very carefully. Additionally, it has to be stored very carefully. One of the things a railgun hypothetically allows is launching non-explosive inert projectiles. What happen when you launch a big hunk of steel at something 200 miles away travelling Mach 6? Another huge benefit is the speed a…

I’m very ignorant about weapons technology. When you say anti-air does that imply some kind of homing technology in the projectiles?

I find the physics of rail guns pretty fascinating. For something nominally invented in world war 1 (1918) which is now "only a few years" away from possible deployment. We are talking literally a 100 years later. We went from powered flight to flying in orbit in less time, think about that.

Is it a compelling weapons concept? Of course it is, you don't need explosives to shoot things that is pretty huge. Are wars bad? Of course they are.

That said, the concept has been around for a hundred years, so people are going to work on making a practical weapon out of it. Which means that at some point its going to be a component of a military action. And not having one of your own, will change the calculus of what you can and cannot do.

Am I supposed to celebrate the spending of untold billions on an unnecessary weapon of death while my Bridges and roads crumble, my health care system sucks and absolutely nothing is being done about, or to prepare for, climate change?? I'm not impressed

> Am I supposed to celebrate the spending of untold billions on an unnecessary weapon of death ....

It'd be wonderful if it were indeed unnecessary. But the human species evolved in an environment where it was adaptive to seek power and dominance. Many individuals, groups, and nations still engage in that quest — even though in time it could lead to a very bad outcome (and might explain the Fermi Paradox [0]).

We could, of course, accept that others will achieve superior weaponry and that in due course we'll surrender to them. That doesn't sound so appealing. Unfortunately, the only practicable alternative, at least for now, appears to be to continue to compete in the arms race. It'd doubly unfortunate because there are so many more-constructive things that we'd prefer to spend the money on — if we had the choice.

EDIT: An analogy: I live in Houston, very near the Texas Gulf Coast. It'd be great if we didn't have to spend so much money on hurricane- and flood preparation; it's easy to think of better uses for that money. But if we didn't spend the money on hurricane- and flood prep, then we'd risk losing much of what we do have, to forces over which we have no control (at least not in the near term).

I am not foolish enough to predict the future, nor what said future will demand of us. Two nuclear weapons ended World War 2. Seconded guessing hard decisions is a privilege of existing in the future after those decisions were made, a privilege that one might not otherwise have had.

Do you feel better about using a nuclear weapon over a chemical weapon? Why or why not? Once death is assured, we’re just arguing time and the experience.

War in general is terrible and merciless, and should be avoided at all costs. I can be a pacifist but still want to pull out all of the stops when the devil comes knocking.

As usual, I find the music in all of the linked videos delusional, as if this high-tech killing machine was created to astonish patriotic five-year-olds. For the sake of analogy, someone should overlay the same music to the engineering of a-bombs and gas chambers.

To my ears, the track of the first video sounds like a royalty free copycat of Hans Zimmer's Pirate of the Caribbean soundtrack.

In the context of a new canon to be installed on the Navy's ships I think it fits pretty well. It does not sound nationalistic or over the top to me.

The other videos are on personal channels so they are inconsequential.

Jingoistic is exactly the word that came to mind as I watched the video.

Perhaps it is the appropriate word here. However, I think it undermines the bigger picture. Many of these weapon showcases are made at the behest of weapon companies, the items of which are sold to the highest bidders.

See Vice's coverage of SOFEX on Youtube for a good showcase of delusion.

It's not like the technology behind railguns hasn't been stable and ready to use for decades now. It's just that, until the more recent invention of ancillary technologies like supercapacitors, it's been so costly to fire them that there was no logical place for them on the battlefield, so we never bothered to operationalize them.

We've been stockpiling nukes for a half-century, and only ever used two. I would contend that the two which were used were a net benefit in terms of what it would have cost (in both American and Japanese lives) to invade the islands.

Of course, the threat is only good if the nation doing the threatening is willing to use it, so the merits of stockpiling are still arguable. With that said, they were something of a tool for a while. It has been argued that Wilson lacked foresight due to his decision to drop nukes, but what would you have done? Would you have been willing to condemn a half-million young American men to die, given the choice?

It's the classic argument, debated since the time of Pericles: is a javelin gone astray responsible for a death?
