Navy Electromagnetic Railgun

The Office of Naval Research (ONR) recently demonstrated the Navy's electromagnetic railgun initial rep-rate fires of multi-shot salvos at the Naval Surface Warfare Center Dahlgren Division. This revolutionary weapon relies on a massive electrical pulse, rather than gunpowder or other chemical propellants, to launch projectiles at distances over 100 nautical miles - and at speeds that exceed Mach 6. "They've extended the launcher core life from tens of shots' core life when program started to something that's now been fired over 400 times and...we anticipate barrels will be able to do over 1,000 shots," said Dr. Tom Beutner, head of Naval Air Warfare and Weapons for ONR.

Navy Laser Weapon

Developed by the US Navy, the AN/SEQ-3 Laser Weapon System or XN-1 LaWS is basically a directed-energy weapon designed to be used against low-end asymmetric threats. Scalable power levels allow it to be used on low-power to dazzle a person's eye to non-lethally make them turn away from a threatening posture, and increase to 30 thousand watts (30 kW) to fry sensors, burn out motors, and detonate explosive materials. Against a vital point on small UAVs, one can be shot down in as little as two seconds. When facing small boats, the laser would target a craft's motor to disable it and make it "dead in the water," then repeating this against others in rapid succession, requiring only a few seconds of firing per boat.

F-35 Gun Pod


The US Marine Corps' F-35B just made history by firing its gun pod while flying for the first time. This weapon straps onto the belly of the aircraft, and enables the fighter the option to sacrifice a little stealth, drag, and range for 220-rounds of 25 mm firepower - a big upgrade from the 20 mm guns that current US fighter jets carry. One caveat: though F-35 can fire its gun while flying, the software update needed to properly aim the gun remains elusive, but should be coming later this year.

Nerf Mass Effect


When is a NERF gun not just a toy? When The Hacksmith gets his hands on one of them. To be more specific, it shoots red hot ferrocerium, which explodes on impact into a cloud of sparkling shrapnel in excess of 3000° C. How does it work? It's basically an air gun that shoots a custom over the barrel ferrocerium dart, heated by a 1000W induction coil until it is glowing red. The key to not getting burned is a string from the trigger to trip the quick release valve. Click here to view the first image in today's viral picture gallery.

Blitzer Railgun

General Atomics Blitzer system is the world's first weaponized railgun planned for production. It basically launches a streamlined discarding sabot round designed by Boeing's Phantom Works at 1,600 m/s (5,200 ft/s) - approximately Mach 5 - with accelerations exceeding 60,000 gn. In one of the latest tests, the projectile was able to travel an additional 4.3-miles downrange after penetrating a 1/8 inch thick steel plate. The company is aiming for mass production by 2019, pending funding, as the project is thus far self-funded. Click here to view the first image in today's viral picture gallery.

Fedor Terminator Robot

Officially called a "cyber cosmonaut," the 6-foot-tall FEDOR robot has also been given the nickname of "Terminator" after demonstrating that it can shoot a gun using both of its hands. "The robot of the F.E.D.O.R. platform showed skills of firing using both arms. Currently the work on fine motor skills and decision algorithms is underway. This thing can work without a space suit, live not only in a crew vehicle, but even outside it," said deputy premier Dmitry Rogozin.

Navy Railgun

The U.S. Navy plans to integrate a railgun that has a range of over 160 km (100 mi) onto a ship by 2017, and this weapon will utilize components largely in common with those developed and demonstrated at Dahlgren. The hyper-velocity rounds weigh 10 kg (23 lb), are 18 in (460 mm), and are fired at Mach 7. The railgun was originally scheduled for testing at sea on the USNS Trenton this year, but plans for that have been pushed back to late 2017, or early 2018.
