    The US Navy has been testing its railguns, which fire shells at high velocity using electromagnets instead of explosive propellant, for years. Test footage emerged in 2012 showing off successful demonstration of the experimental weapon on land targets. But at long last, the military's new artillery piece is ready for live-fire testing in the field.

    The US Navy's latest toy, a railgun that can fire projectiles at seven times the speed of sound, maybe be deployed sooner than thought. The original plan was to test it on joint high-speed vessels (JHSVs) in 2016, but the Navy is reportedly building an operational unit that could be installed on the USS Lyndon. B. Johnson, according to the Associated Press. That ship, the last of three Zumwalt-class destroyers, would be an ideal candidate because its Rolls Royce turbine generators produce 78 megawatts, more than enough to power the electromagnetic weapon.

    Used to be that if you wanted to fire off a few high-velocity rounds with an electromagnetic railgun, you'd have to land a commission aboard the USS Ponce. That is, until YouTuber Ziggy Zee went ahead and built one from scratch -- no 3D printing required. The 250 pound device utilizes 56, 480-joule capacitors driven by a 400-volt power source to launch its aluminium projectiles with a staggering 27,000 joules of force.

    An ambitious maker has built a partly 3D-printed railgun that can fire aluminum or graphite projectiles at over 250 meters per second (560 mph). No, this isn't Quake, but it's no janky, all-plastic gun, either. The "handheld" weapon houses six capacitors that weigh 20 pounds and deliver over 1,800 joules of energy per shot. And it indeed works just like a full-sized railgun, using parallel electrodes to fire an "armature" bullet. The creator, David Wirth, added an Arduino Uno R3 to monitor charging levels, temperature and other factors, and tweaked the rails after he noticed "plasma damage."

  • Watch the Navy's electromagnetic railgun blow stuff up before it hits the high seas

    The Navy announced plans today to deploy an electromagnetic railgun that can do some epic damage. Set to go into testing on one of Navy's joint high speed vessels (JHSV) in 2016, the gun uses Lorentz Force to "rapidly accelerate and launch a projectile between two conductive rails." The result is a gun that can shoot a ton farther than a traditional weapon. Even better, it can maintain kinetic energy while it's in flight, making it so it doesn't need a lot of explosives on board to do some damage when it gets to the car, building, or other ship you're trying to blow up. The Navy's chief engineer, Rear Adm. Bryant Fuller says the gun will "allow us to effectively counter a wide-range of threats at a relatively low cost, while keeping our ships and sailors safer by removing the need to carry as many high-explosive weapons." JHSV's aren't used for combat, so the railguns will be on their way to some TBD boats soon. For now, you can see them in action in the official Navy video below.

    It's been just under three months since EVE Online's exploration-focused Odyssey expansion went live, bringing in a new hacking minigame and significantly buffing the underused tier 1 and tier 2 battleships. With a complete rebalancing all of the tech 1 sub-capital ships now complete, CCP has turned its attention to some of the oldest tech 2 ships in the game: Heavy Assault Ships and Command Ships. Developers have been testing out changes to these ships on the test server and hitting up players for feedback since Odyssey went live, and the results are finally ready to deploy. Odyssey 1.1 will go live in two days time on September 3rd and contains some pretty big changes that are sure to shake up the PvP landscape. Medium-sized long-range weapons have been buffed beyond all recognition, and a buff to active tanking may soon make it viable in PvP. Heavy Assault Ships and Command Ships have been beefed up, the Dominix is getting a small nerf following its absolute dominance in the Alliance Tournament, and the Nosferatu energy vampire module may be about to make a return to PvP setups. In this week's EVE Evolved, I analyse the upcoming Odyssey 1.1 patch and what the new ship balance changes mean for the average player.

  • Navy awards weaponized railgun manufacturing contract to BAE Systems

    Just over 18 months after making its video debut, the Navy's electromagnetic railgun has a manufacturer. BAE Systems -- known for e-ink-powered tank camouflage, autonomous spiderbots and machine-gun-mounted lasers -- won the government contract and hopes to have phase-two prototypes ready "as early as next year." While the current design is capable of firing one shot, the Office of Navy Research hopes for six to ten shots per minute. If that doesn't scare you, consider this: The pulse-driven projectiles travel at Mach 6 and can hit targets over 100 nautical miles away. Don't worry, it's not too late to rethink that career of sailing the high seas as a pirate and get to work on that accounting degree instead.

    In each of my MMOs, I know my weapons intimately. In Star Trek Online, it's a plasma railgun that spits glowy death at 5,000 shots a minute. In Lord of the Rings Online, it's a legendary spear that I've named Metroid. In Guild Wars 2, it's a ferocious flamethrower that's laid waste to most of the civilized world. Burn, baby, burn! Sometimes we're constrained by class and available drops to what weapons we equip, but chances are that you've had a favorite or two in there. Maybe it was a weapon that had a cool design or proc'd a neat effect when used. Perhaps it's something that took you a lot of effort to acquire or create. Or it could just be a weapon that completely gels with your personality. Open up the door to your armory -- and heart -- and sound off about your favorite weapon! Every morning, the Massively bloggers probe the minds of their readers with deep, thought-provoking questions about that most serious of topics: massively online gaming.

    You're about to watch a test firing of BAE's experimental railgun demonstrating why the technology isn't science fiction anymore. Load an aluminum projectile into the 12-meter barrel and one million amps will hypersonically propel it toward the target. The conflagration you'll witness is due to the metal slug burning off in the charged air. In April, General Atomics will supply its own prototype so the military can identify which one is closer to making its way aboard the battleships of the 2020's. Anyway, now you can go watch the video fully aware of what's going on, try not to sit there with your mouth open.

  • US Navy ship-mounted railgun closer to reality, Raytheon and others to make it happen

    Ah, the railgun. Previously a flight of fancy fit only for wars in works of science fiction, the ultimate in electromagnetic weaponry is one step closer to becoming a reality for the US Navy. We've seen the system working well in the lab, but Raytheon has just gotten $10 million to create the pulse-forming network needed to get a railgun flinging projectiles off the deck of a Naval warship. Making such a network isn't easy, as it must store massive amounts of energy in a small enough package that it can be "used in a modular and versatile way for multiple platforms" -- so that some day, even dinghies will have 33-megajoule stopping power on board. In addition to Raytheon's pulse-forming framework project, the Navy has already tasked BAE and General Atomics to design tactical technologies that'll get future railguns firing up to ten rounds per minute. When can we expect to see such kinetic weapons on the high seas? The goal is 2025, but naturally, finances and politics will dictate its date of deployment, so keep your fingers crossed it's sooner, rather than later.

  • EVE Evolved: Fitting the Caldari Naga

    While EVE Online's recent Crucible expansion brought us over a hundred small features, balance tweaks, and graphical updates, its headline feature was undoubtedly the four new tier 3 battlecruisers. It's been several years since a new combat ship was added to EVE, and combat had begun to get a little stale. Most of EVE's ships follow a logical design progression, with larger ships having more tank and higher damage output. CCP turned that concept on its head with the new tier 3 battlecruisers, which deal battleship-class damage but have both the agility and paper-thin tank of a tech 1 cruiser. The Caldari Naga is the very definition of a glass cannon, able to output more damage than a Megathron or Rokh but at the cost of having practically no tank. It can be sniper-fit to deal around 650 DPS at ranges of 100-130km, blaster-fit to output a raw 1,500 DPS at ranges below 10km, or even set up to fight effectively with blasters outside web range. Its high top speed and cruiser-like agility add new gameplay options to existing sniper and heavy damage-dealer fleet roles, providing battleship-class damage for roaming cruiser gangs. It's a potential game-changer for nullsec alliances engaging in hit-and-run style warfare, but as with all new ships it can be difficult to figure out an effective ship fitting. In this week's EVE Evolved, I explore three solid fittings for the Naga designed to fill common PvP roles.

  • EVE Evolved: Gallente and hybrid balance

    It's been another week filled with announcements and positive news for EVE Online, with CCP showing off EVE's new nebulae and revealing the Amarr and Caldari tier 3 battlecruisers. For Gallente pilots, no news was celebrated more than the rebalancing of hybrid weapons and ships that specialise in their use. Short-range blasters can technically deliver the highest damage output of any turret, but their extremely short optimal range means they deal a smaller fraction of their maximum damage in most fights than other ships. Blaster ships have to spend valuable travel time closing into weapons range, and once up close, targets are hard to track. Although railguns were designed by the Caldari, they're hybrid weapons just like blasters, and so they are the long-range weapon of choice for Gallente sniping and mission-running ships. They have good range and tracking speed but have always suffered from slightly worse damage output and alpha strike than beam lasers and artillery cannons of the same size. Countless suggestions for fixes to blasters and railguns have appeared on the forum over the years, but until now they've remained unchanged. As a Gallente pilot and avid Thorax and Dominix fan, I'm very excited by the hybrid balance changes coming this winter. In this week's EVE Evolved, I take a break from the new player experience experiment to take a look at the impact of the upcoming hybrid balance patch and why the announced changes are needed.

  • US Navy's electromagnetic railgun hits testing milestone: 1,000 shots fired

    If there's one thing you want your multi-million dollar electromagnetic railgun to be, it's reliable, and the US Navy announced today that it's reached a key milestone towards that goal. It's now successfully fired its prototype gun 1,000 times, which translates to as many as 15 shots per week. In recent years, those tests have generally been conducted at a 1.5 megajoule launch energy, which the Navy puts into perspective by noting that "a one-ton vehicle moving at 100 mph has approximately one megajoule of kinetic energy." Eventually, the Navy hopes to install even more advanced and far more powerful railgun weapons systems on ships, although the project's future remains a bit up in the air given some recent funding battles in the US Senate.

  • Details of EVE's long-awaited hybrid balance patch revealed

    Balancing combat in a PvP-centric game like EVE Online is a tricky business. In a sandbox universe that pits fleets of hundreds of ships against each other in a struggle for territorial dominance, balance changes can alter the PvP landscape. Unfortunately, hybrid weapons have always received the short end of the stick in balancing efforts, leaving Gallente turret ships like the Deimos and Megathron behind their Amarr and Minmatar counterparts. In a new devblog, CCP Tallest adds a major Hybrid weapon rework to the growing list of long-awaited features finally making an appearance in EVE's coming winter expansion. Blasters will be receiving some much-needed CPU and powergrid reductions, a 30% reduction on capacitor usage and a huge 20% bonus to tracking speed. Railguns receive the same CPU, powergrid and capacitor reduction as blasters, in addition to a straight 10% damage increase. All ships typically fit with blasters will also be getting speed bonuses to help them get into blaster range, and tech II ammo for all turrets is due for an update.

  • Navy's prototype rail gun projectile hits mach 7 at 33 megajoules, our hearts skip a beat (video)

    Rail guns play a major part in nearly every fanciful battle of the future, whether it be giant robots fighting for control of the Inner Sphere or the last remaining member of Noble Team holding off the Covenant invasion for as long as possible. They're the stuff of geeky dreams, and thanks to the US Navy they're closer to deployment than ever. Three years ago our sea-borne force managed an 8 megajoule blast, now its researchers have more than quadrupled that: 33 megajoules accelerating a projectile using magnets. That power means speeds of Mach 7 for the slug and a current range of 100 miles, though the hope is for at least double that by the time these things start finding themselves mounted on the decks of battleships in 2025. At that point they'll reduce the need for rooms full of powder charges and the associated dangers that come along with explosive shells, but will instead need to make way for what looks to be a warehouse full of capacitors. There's a video of the thing in action below, and you'll be sorry if you miss it. [Thanks, Jacob L.]

  • Navy develops 8-Megajoule railgun, Nukem bows down

    The mere mention of the word brings back visions of the original first-person-shooters to grace our now-antiquated machines, and now the US Navy is getting real personal with a realized version of the pixelated railgun we all love and adore. Presumably ripped straight from the (admittedly lacking) storyline of Quake, an 8-Megajoule railgun has been officially created, fired, and deemed worthy of flanking our naval ships, which should strike fear in the hearts of anyone wishing us harm. The gun was showcased this week at the Naval Surface Warfare Center at Dahlgren, Virginia, and utilizes massive quantities of electricity rather than gunpowder to propel "nonexplosive projectiles at incredible speeds." The weapon is powerful enough to equal the damage inflicted by a Tomahawk cruise missile, and the device's project director compared the impact to hitting a solid object "going 380 miles-per-hour in a Ford Taurus." Moreover, the railgun touts a 200 to 250 nautical-mile range, compared to the 15 nautical-mile range that current five-inch guns sport now. Interestingly, the weapon should "only" cost around $1,000 per shot once loaded onboard, which is chump change compared to the cool million that vanishes each time a cruise missile is deployed, and if everything goes as planned, we'll be seeing a 32-Megajoule prototype in June, with a 64-Megajoule rendition adorning our ships by 2020.[Via Slashdot]
