Two questions: 1. How practical is that thing in terms of energy requirements, maintenance, etc. 2. How is it superior to conventional ordnance? Is it the answer to a Buck Rogers question that really doesn't need answering? I mean, it's cool and all, but isn't it bazillions of dollars when we already have guns? See how silly that sounds now? As for cost, there is no way this is in any way more cost effective than missiles or even conventional guns. Sure the ammo might be *relatively* cheap (but I'm sure they will still find a way to make each slug cost $10,000) but the gun itself probably costs a hundred times what a missile cell or naval gun does. Is it cool? Heck ya it is, but in this era of hyperaccurate precision guided munitions what problem is this going to solve? What question is this the answer to? |

Hyper velocity projectiles will cause significant damage. Not having to store a lot of high explosives for your HE rounds or missiles is a plus for safety. How many missiles can you store? How many rail gun projectiles can you store instead? Probably a considerable amount more. It's like carrying a crew served .50cal with limited ammo (heavy) vs. A .556 with 300+ rounds per person. Way more ammo can be carried. Also what are the other ships that you are assigned with? Say this goes on a particular destroyer. You have other destroyers and cruisers in the group that also have sea to air, sea to land, and sea to sea missile systems. The range is incredible on these as is the speed. Given the speed and size of the projectile, you will really tax the enemy's radar systems. Im guessing they'll see an in coming missile long before they pick up this projectile. It's also moving so fast that it will be difficult to counter. Thinking out loud ... ... It's as if now the ship can become the sniper running hard target interdiction missions. They can take out heavily fortified and defended radar emplacements that perhaps our F35's and F22's can't penetrate. |

We spend money now so 50 years from now a doe-eyed FC can click a button and kill a couple thousand Chinese guys inside a tin can before they even realize it. While the same ole "don't underestimate the republican guard" guys are typing away on their keyboards. We have reached a precipice in warfare when we WANT our enemy's to have armored divisions, fighter wings, navy's just so we can force a checkers player into playing chess... then we proceed to ruthlessly destroy them.
By the time China has completed it's trials and amassed a couple of copy cat aircraft carriers we will have to ability slap holes into their hulls from 200 miles way before any radar system even so much as squawks a warning. Operationally they will have learned nothing and technologically since its mostly stolen shit they will not have advanced to a "near-peer" status. Rail guns are going to be the new best thing in surface warfare much to the dismay of our enemy's. Well be having a discussion about stolen railgun tech from _____ country in about 100 years as well Money well spent |

Sounds awesome but how effective will it be. I'm assuming these fast rounds will not be guided and the idea is long range so how accurate will they be? Naval bombardment of inland cities from international waters with cheap munitions. America! Given most of the world's population lives within 300 miles of a coastline, I don't think it's possible to overstate the impact of a future generation battleship mounting large railguns that could do sustained naval bombardment of targets ~300 miles inland with a projectile that can't be intercepted like a fighter or missile can. Could be a game changer for BMD too. Quoted:

That was a major selling point - getting the energetics off ships. Another plus is you basically at least double your magazine capacity because you no longer have to carry separate powder charges. Safety comes into play because you can't get a round cooking off in a hot gun. Believe me, a misfire in a hot gun is an asshole puckering event! A capacitor that big exploding would be "exciting" though... View Quote The about the amount of energy needed in a capacitor to DELIVER that amount of energy to a projectile. I am beginning to think that LOVA is a hell of a lot safer. |

Neat. Can someone explain the muzzle report? Is it just a reaction from heat with the atmosphere? I was under the impression an inert slug was accelerated with magnets, so there wouldn't be some chemical reaction on that end. ETA: Beat by a few minutes. View Quote |

View Quote Lets say they get 100 mile ranges. The German/Polish border is only 290 miles across. Theoretically you would only need 2 batteries of these and you can kill anything the USSR could have thrown over. Compare that with the number of conventional artillery we would need. Right now we drop bombs that cost $26,000 from $178,000,000 aircraft. Plus fuel cost. Plus maintenance cost. OR, we shoot some $500 Tungsten slugs at them from 100 miles away. |

Imagine this:
1. An old classic battleship whose main guns are now rail guns! Nuclear powered of course, and the multiple guns allow time to reload and capacitor recharge for a near continuous firing regimine. 2. A CWIS....but as a rail gun! (Of course given they have multiple banks of capacitors set up to discharge and recharge in a sequence that allows the high rate of firing. May have to decrease power a little to adapt). A cwis rail gun. Wow, now take that CWIs and use it for FOB defense. Now consider that the CWIS uses a special radar tracking and targeting system. We will have to upgrade that as well to keep up. The side benefit is this may help better track and identify the fast movers (We're developing hypersonic jets and missles. China and Russia both have hypersonic missiles. This better radar would then help defend our ships better in the Pacific...) Just a few wild examples. But the point is this: often times when you are developing a new technology, many other technologies are affected in a way that requires them to be improved as well. So in my thought scenario, not only do you get a rail gun, but better radar systems, better energy storage systems, better offensive and defensive weapons, tip the balance in your favor (much like the nuclear deterrent strategy). As per radar, ships radar could improve but would still be limited by the 200 or 300 miles projectile range. Without an internal guidance system in the projectile to accurately fire beyond visual range (see F35's and F22's bvr capabilities), we would still have to depend on the AWACS system and other eyes in the sky to locate targets and be impact spotters. To fully take advantage of this technology, you will by necessity have to improve other technologies as well. |

Why not have a sacrificial rail layer that gets replaced after every few rounds? It could be fed into a channel and the new material be stored in a magazine to the rear. Fire a few shots, then before the rail gets completely melted and distorted, have some drive motors pull and eject the rails out the front, then new ones feed from the rear. Im sure they've thought of this though. View Quote Also, I too am always stunned at the innovation haters. Just imagine what this can do to a ship. Like say a Chinese aircraft carrier. From outside of ASM range. Throw a kickass radar on it, and you have the capability to very realistically shoot down an ICBM. Envision what an APFSDS does to a tank, and try to picture what a smaller version can do to a tank. Without the radioactive sludge produced, and no danger of your tank's magazine cooking off if you get hit. Aerial bombardment, right now in cities, the US hamstrings itself due to fear of collateral damage created by the blast radius of an aerial bomb. Fire this bastard down from the sky and you'll hit a building with absolute precision and enough force to crumble it without destroying anything the politicians care about. Figure out the power problem and you can turn it into a rapid fire CAS system. Launching satellites, space combat. This is a revolutionary technology in its early stages. |

23 mile range for surface bombardment. $500 7# steel slug hitting like a 1000# bomb at Mach 7. The idea is to put it on figures and destroyers for shallower waters for surface support or closer range fucking things up. Still a hell of a lot safer than a full magazine of shells if something goes wrong or they take a hit. Then again, fuck if I know what will happen if caps that big pop off. View Quote |

Already discussed above, but it's lasers:
The AN/SEQ-3 Laser Weapon System or XN-1 LaWS[1] is a directed-energy weapon developed by the United States Navy. The weapon was installed on USS Ponce for field testing in 2014. In December 2014, the United States Navy reported that the LaWS system worked perfectly, and that the commander of the Ponce is authorized to use the system as a defensive weapon.
... ... In September 2014, the LaWS was declared an operational asset, so the ship commander has permission to use it for self-defense. Humans are not a target of the weapon under stipulations of the Convention on Certain Conventional Weapons, but targets do include UAVs, helicopters, and fast patrol craft. Rules of engagement have been developed for its use, but details have not been released. The Navy has released video of the LaWS on deployment disabling a ScanEagle UAV, detonating a rocket propelled grenade, and burning out the engine of a rigid hull inflatable boat. Officials said it is working beyond expectations. http://www.defense-aerospace.com/articles-view/feature/5/159975/2015-ushers-in-era-of-laser-weapons.html More info here |
