Slow, but rugged, Curiosity's computer was built for Mars

The electronic brain controlling NASA's Curiosity Mars rover has far less horsepower than the microchips typically found in a modern smart phone.

But the RAD750 PowerPC microprocessor built into the rover's redundant flight computers has one enormous advantage: It was engineered to be virtually impervious to high-energy cosmic rays that would quickly cripple an iPhone or laptop computer.

The radiation-hardened single-card computers, built by BAE Systems in Manassas, Va., are designed to withstand charged ions and protons in interplanetary space or on the surface of Mars that can physically damage integrated circuits or trigger so-called "bit flips&… Read more

Navy tests railgun that can shoot up to 100 miles

The U.S. Navy says it has tested one of two prototypes of its futuristic electromagnetic railgun, a weapon that could fire a 5-inch projectile up to 100 miles, yet which requires no explosives to fire.

The Office of Naval Research is evaluating competing railguns--one from BAE Systems, and one from General Atomics. Yesterday, ONR announced it has completed a successful test of BAE's model, and the Navy is expected to test-fire General Atomics' offering sometime in April.

"The firing at Naval Surface Warfare Center Dahlgren Division...kicks off a two-month-ling test series by [ONR] to evaluate the … Read more

Heading into battle? Don your invisibility cloak

Defense supplier BAE Systems is outfitting tanks, warships, and helicopters with an "invisibility cloak" that can help them escape detection by infrared and other surveillance technology frequencies.

Known as Adaptiv, the invisibility cloak is made up of a durable layer of large, hexagonal "pixels" that can change temperature very quickly. Cameras mounted in the vehicle detect its surroundings and tell the pixels to match and blend into the background, even while they're in motion. When viewed in the infrared spectrum, the vehicles can't be detected.

The pixels can also be used to change a … Read more

Boeing building lasers for Navy machine guns

Boeing is formally joining an effort to give directed-energy capabilities to U.S. Navy machine guns through a BAE Systems effort to develop the Mk 38 Mod 2 Tactical Laser System.

The technology will unite a solid-state, high-energy laser weapon module with BAE's Mk 38 Mod 2 gun system. It will add adjustable levels of laser energy to counter threats such as small boats and UAVs.

"This is revolutionary--to combine kinetic and directed energy weapons capability into one system," says Boeing spokesperson Elizabeth Merida. "Adding the laser system provides extremely precise targeting ability."

The tie-up … Read more

Unmanned stealth plane may pick its own targets

Britain's Ministry of Defence recently unveiled an unmanned stealth attack aircraft that redefines "autopilot"--it's designed to fly halfway around the world and choose its own targets without human intervention, according to a report in The Globe and Mail.

Named after the Celtic god of thunder, the Taranis is designed to fly much farther than conventional drones, which typically support troops or carry out air strikes in a limited area. Controlled by ground-based human operators, Taranis is supposed to be able to hit targets on other continents; it's unclear when the target-picking AI skills would … Read more

GAO calls rush to field F-35 strike-fighter not 'prudent'

The Department of Defense's $1 trillion-plus plan to build and deliver multiple versions of the Joint Strike Force (JSF) aircraft to multiple customers is behind schedule, over budget, and upside down, according to a report from the Government Accounting Office (PDF).

Upside down because the military is accelerating procurement of operational aircraft before it has even taken delivery of test units, according to the non-partisan GAO.

"Procuring large numbers of production jets while still working to deliver test jets and mature manufacturing processes does not seem prudent," the report states.

The JSF program, personified by the F-35 … Read more

Scientists open door to low-cost titanium

Scientists at Oak Ridge National Laboratory (ORNL) are using low-cost titanium powders to develop lightweight, corrosion-resistant, bulletproof alloys for military vehicles and what they hope to be other military and commercial applications.

The latest project is a titanium door for the next-generation Joint Light Tactical Vehicle, which is meant to replace the Humvee and other front-line conveyances.

"By using a titanium alloy for the door, BAE Systems was able to reduce the weight of its vehicle yet at the same time decrease the threat of armor-piercing rounds," said Bill Peter, a researcher in ORNL's Materials Science and … Read more

Rail gun uses kinetic energy to deliver Mach 5 wallop

The U.S. Navy is installing an electro-magnetic laboratory rail gun at its Surface Warfare Center in Dahlgren, Va., bringing it one step closer to developing a ship-mounted version of this futuristic cannon.

The 32-megajoule weapon appears to be the largest rail gun ever built, according to defense contractor BAE Systems. A joule is what's needed to produce one watt of energy for one second.

It uses a magnetic "rail" instead of a chemical propellant like gunpowder to heave projectiles at Mach 7 for what could be up to 220 miles down range--that's 10 times farther … Read more

It's a car, it's a UAV, no - it's UUV

As we see here, there is absolutely no reason why your pool cleaner shouldn't match your car. Too bad British defence giant BAE Systems has other plans for the Talisman -like minesweeping.

Drawing on stealth, aerospace and race car design, BAE developed this unmanned underwater vehicle (UUV) in hopes of following up on its success with the unmanned aerial variety. After years of wind tunnel and open-ocean testing the carbon fiber hulled Talisman M is ready for action in water up to 490 feet. "Vectorable" thruster pods allow it to hover and turn on a dime. It … Read more
