Blowing things up from far away

rail-guns-navy Everyone knows spaceships will have laser guns that go “pew, pew” and kill the fat guy in the x-wing.  But until then, we’ll have to make do with blowing the crap out of stuff at 220 miles with the most powerful rail gun ever.  The 32-megajoule Electric Laboratory Rail Gun (a name only a military bureaucrat could love) is four times more powerful than the previously-most-powerful rail gun, capable of accelerating steel slugs to Mach 7.

The scary thing is, this model is only half as powerful as the specifications given by the Navy – they want a 64 megajoule weapon.  BAE’s got a ways to go, the current model only lasts a few shots before blowing itself out of alignment.

Military exoskeleton prototype – mech-warriors in the offing

Sarcos robot exoskeleton It’s not quite the loader that Ripley uses to ass-kicking effect in Aliens, but it’s a (mechanically augmented) step in the right direction. A robotics startup called Sarcos has been demoing a prototype robotic exoskeleton that mimics the movements of its human operator while amplifying his (or her) strength. Don’t rush off to your local recruiting station just yet, though – Sarcos estimates a five year development process before the suit is ready to rock. There’s a video if you want to click through on the link, by the way. [Via OhGizmo!][Image lifted from linked article]

New fighter pilot helmet makes plane "invisible"

20071108_Testhelmet_600x400 Not invisible to other pilots: invisible to the pilot him (or her) self. (Via DefenseTech.)

Unlike modern fast jet aircraft the Joint Strike Fighter, which is planned to replace the famous Harrier, does not have a ‘traditional’ head-up display – instead the computerised symbology is displayed directly onto the pilot’s visors.

This Helmet Mounted Display System provides the pilot with cues for flying, navigating and fighting the aircraft. It will even superimpose infra-red imagery onto the visor which allows the pilot to ‘look through’ the cockpit floor at night and see the world below.

It’s being developed by Vision Systems International and Helmet Integrated Systems, and is currently being evaluated by defence scientists at Boscombe Down in Wiltshire.

As you can see from the photograph, it also makes anyone wearing it look wicked cool. Or maybe just wicked. (Photo from U.K. Ministry of Defence.)

Building a better bulletproof vest

The first bulletproof vest, made by the Polish inventor Jan Szczepanik. Bullets don’t just bounce off Superman, they don’t even slow him down. Real-life police and soldiers can’t say the same, even when they’re wearing a bulletproof jacket of Kevlar or something similar. Although bullets don’t penetrate–the bulletproof material spreads their force–the force is still tranmsitted to the tissue underneath the bulletproof shell, causing severe bruising or even organ damage.

Now engineers from the Centre for Advanced Materials Technology at the University of Sydney have found a way to use carbon nanotubes to not only stop bullets penetrating material but actually rebound their force, so bullets can be repelled with "minimum or no damage to the wearer of a bullet proof vest.” (Via Science Blog.)

If they can just nail the X-ray vision, super-strength and flying stuff, they can break out the red-and-blue tights. (Image from Wikimedia Commons.)

Video games make better soldiers

crows.jpgTraditionally, vehicle mounted weapon systems required the operator to be exposed, usually with his head and shoulders sticking out of the top of the vehicle. Obviously this presents an enticing target to the enemy. To overcome this deficiency the US military has developed CROWS (common remotely operated weapon stations). With CROWS, the gunner is inside the vehicle, and observes his surroundings using video cameras with night vision and telephoto capabilities. CROWS also has a laser rangefinder and a stabilization mechanism that allows more accurate fire while the vehicle is moving. But it turns out that the real reason CROWS has been successful is that today’s soldiers grew up playing video games, very similar to the CROWS experience:

Since many troops have years of experience with video games, they take to CROWS quickly, and very effectively. That’s one reason, not often talked about, for the success of CROWS. The guys operating these systems grew up playing video games. They developed skills in operating systems (video games) very similar to the CROWS controls. This was important, because viewing the world around the vehicle via a vidcam is not as enlightening (although a lot safer) than having your head and chest exposed to the elements, and any firepower the enemy sends your way. But experienced video gamers are skilled at whipping that screen view around, and picking up any signs of danger. The army even has a CROWS trainer built into its America’s Army online game.
