Looks like China just installed a railgun on a warship, beating the U.S. Navy to the punch

Pictures surfacing online appear to show a new weapon developed in China. The nation may have just installed a full-scale railgun on a warship, something even the United States Navy has yet to do.



Railguns use electromagnetic energy, rather than gunpowder, to sling a projectile. The concept has been incredibly appealing to militaries, as the weapon offers the speed and efficiency of a cannon, but with the range of a missile.

Photos shared on Twitter show that the Chinese Navy's Type 072III landing ship tank (LST) Haiyang Shan, #936, has a new turret installed on its bow, replacing the H/PJ76F 37mm anti-aircraft turret. There are also three shipping containers.

The turret spotted indicates the presence of a railgun. It's large, for one, with a barrel that measures 26-33 feet in length and 12 to 20 inches in diameter. That's 2-3 times the cannon caliber of conventional tube artillery barrels, which generally have a diameter-to-caliber ratio of 1.25:1. Alternatively, a 350-400mm naval mortar could explain the the barrel diameter and length, but such a large mortar would be hilariously unnecessary.

Due to weight issues, there is virtually no reason for a conventional cannon to have this kind of diameter-to-caliber ratio, and so the barrel's size likely accommodates magnetic rails to propel shells to hypersonic speeds. The shipping containers are another indicator; it's likely they contain some sort of power equipment, like generators or capacitors.

Its barrel length makes the Chinese railgun similar in size to the BAE 32 megajoule railgun built for U.S. Navy testing. The BAE system is designed to fire 22-pound projectiles at Mach 7 speeds to more than 100 miles.

How to save your text messages

For many of us, the humble text message remains an essential mode of communication. But while cloud-based services can back up our emails and social media posts when we lose an old phone or switch to a new one, our SMS (Short Message Service) and MMS (Multimedia Messaging Service) histories tend to disappear.

What Science Says About Arousal During Rape

Rape. Most of us don't like to talk about it. We don't like to think about it. But when we do think about it, or at least when I do, it is always violent. I am struggling and overpowered. I am screaming. And I am certainly not getting off. Although in the United States, where I live, rape survivors are now more common than smokers, I am not currently among the nearly 20% of women or 3% of men (or more) who are sexually assaulted in their lifetimes. I am not one of the 1 in 3 Native Americans who are raped. My mother has never felt the need to tell a doctor, as one Native American mother did, "I need to learn more about Plan B for when my daughter gets raped." And my lack of first-hand experience might be why my narrow definition of rape was completely wrong. Rape is not always violent. Some survivors surrender to protect themselves or their loved ones. Some are intoxicated, drugged, physically or mentally incapacitated, or in a position without powe
