In a side bet on "green power," the U.S. Army has awarded a $1.8 million contract to develop hydrogen filling stations for military vehicles, hoping it pays off with reduced fossil-fuel consumption and increased efficiency.

At first glance, this may appear to be a throwaway investment for the Army. Hydrogen fuel requires such a large amount of energy to separate it from water and to compress or liquefy before it's delivered to the user, that it has been criticized as neither sustainable nor an economic alternative to fossil fuels.

However the contractor, Proton Energy Systems … Read more

The University of Wisconsin-Madison and a Wausau, Wis., company have come up with a 37-inch, bullet and bomb-proof Humvee tire based on a polymeric web so cool looking there's no need for hub caps.

Resilient Technologies and Wisconsin-Madison's Polymer Engineering Center are creating a "non-pneumatic tire" (no air required) that will support the weight of add-on armor, survive an IED attack, and still make a 50 mph getaway. It's basically a round honeycomb wrapped with a thick, black tread.

The military wants an alternative to the current Humvee "run flat" tires, which despite … Read more

It's back. TechX Challenge, the Singapore death-bot battle, has spit out six finalists who are competing for the S$1 million prize and a chance to further this city state's vision of an army on autopilot.

The competition is sponsored by Singapore's Defence Science and Technology Agency (DSTA). The stated objective is to develop an indigenous defense capability for Singapore, but a breakthrough in autonomous, unmanned ground vehicle technology wouldn't hurt weapons sales either.

Experience and resources for the teams that weathered the May semi-finals run the gamut from bootstrap amateurs to international collaborations backed by … Read more

This golf cart-sized, cheetah-spotted buggy could be bad news for those guys who make a living driving up and down the fence lines of Podunk facilities around the country while drinking bad coffee.

The Guardium UGV (unmanned ground system) employs state-of-the-art technologies and any number of payloads to guard places like airports, energy plants and military bases-24/7, rain or shine and without the need for 7-11 pit stops.

A joint venture between G-NUIS Unmanned Ground Systems, Israel Aerospace Industries (IAI) and Elbit Systems Ltd., the Guardium is an all terrain vehicle that takes care of itself.

It uses autonomous … Read more

Another entrant in the race to produce a ducted-fan-propelled, vertical-take-off-and-landing UAV, the planned "humvee of the air" will morph to different missions and reach targets three times faster than helicopters, according to the manufacturer.

The official name of the vehicle is VTOL-Swift Tactical Aerial Resource, or V-STAR. With a cruising speed of 288 knots, a 650-mile range and a 400-pound payload, the V-STAR promises to be a "breakthrough solution for frontline military logistics," according to Broomfield, Colo.-based Frontline Aerospace. The aircraft would use a Rolls-Royce gas turbine with counter-rotating blades and "diamond-box-wing" design … Read more

All the king's horses include this "Stallion," a 4x4-wheeled, all-welded armored scout car with optional 50-caliber weapon station designed and built by the King Abdullah II Design and Development Bureau (KADDB) in Amman Jordan.

The cozy three-seater was designed to be used by peacekeepers, "internal security," and what looks like divot repair out on the Bisharat back nine.

KADDB was established by Royal Decree in 1999 to supply "independent, high-quality, scientific, and technical services" to the Jordanian armed forces and to help the nation in creating a sustainable industrial base along the way.… Read more

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

Check out the schnoz on this one. D?sseldorf based Rheinmetall advertises its Gefas (Gesch?tztes Fahrzeugsystem) as the "safest, most future-proof system of its kind anywhere."

The conceptual model shown here was configured for convoy protection. Some options include a high-powered, electromagnetic, counter-IED system, an automated weapons station controlled from safely inside the vehicle, electro-optical sensor systems with downstream image processing for detecting and tracking moving targets, a 12-meter tactical radar, laser-optical sensors for detecting enemy optics, and an "instantaneously activated" smokescreen.

Gefas replaces standard steering and braking with a hybrid-electric Renk "drive … Read more

Despite the pickup truck and cow catcher styling, the prototype of the military's new Joint Light Tactical Vehicle (JLTV) from Oshkosh Truck and Northrop Grumman promises better maneuverability, survivability, and payload capacity over the HMMWV it's designed to replace.

The U.S. Army and Marine Corps want something that comes armor-equipped, fuel-efficient, and air-droppable. It also wants a vehicle that can run on two flats and endure sustained small-arms fire. But most of all, performance must "exceed" that of the HMMWV, better known as the Humvee--which means it has to be more mine-resistant and ambush-proof than … Read more
