A company based in Berkeley, CA, is developing lightweight, high-energy batteries that can use the surrounding air as a cathode. PolyPlus is partnering with a manufacturing firm to develop single-use lithium metal-air batteries for the government, and it expects these batteries to be on the market within a few years. The company also has rechargeable lithium metal-air batteries in the early stages of development that could eventually power electric vehicles that can go for longer in between charges.

Revolutionary Armour Unveiled at Defence Equipment Event
A ground-breaking armour system and a fleet of new armoured vehicles that will provide better protection to troops in Afghanistan were unveiled at the Defence Vehicle Dynamics (DVD) event yesterday, Wednesday 24 June 2009.
The revolutionary, textile-based TARIAN vehicle armour system will give lightweight protection against rocket-propelled grenades, in place of the current bar armour that is fitted to vehicles such as Mastiff and Ridgback.

Kongsberg Receives New Air Defence System Order for the US Army
KONGSBERG has as a partner of a Raytheon team, booked an order valued at MNOK 23 from fellow team member, the Boeing Company. The order approves the long-lead purchases, leading to low rate initial production of the MNOK 91 Surfaced Launched AMRAAM (SLAMRAAM) Program for the US Army. Full rate production is expected to start in 2012, at a value of approximately MNOK 500 for KONGSBERG, if all options are executed.

NGC and USAF Unveil Next-Gen of High-Flying Global Hawk
Northrop Grumman Corporation unveiled the next-generation of high-flying unmanned aircraft - the RQ-4 Block 40 Global Hawk - in a ceremony today at Northrop Grumman's Palmdale, Calif., manufacturing facility.
"This unveiling of the first of 15 Block 40 aircraft is a significant step to fielding Global Hawk to Grand Forks Air Force Base, North Dakota, in 2010 and reaffirms our excellent track record of delivering Global Hawks since low rate production began," said Duke Dufresne, sector vice president for Northrop Grumman Aerospace System's Strike and Surveillance Systems Division. "Carrying an advanced, all-weather multi-platform radar technology insertion program (MP-RTIP) sensor, the Block 40 aircraft will provide game-changing situational awareness for our warfighters with its unprecedented capability to detect, track and identify stationary and moving targets."

Fanless Computer features waterproof, rugged design
Stealth.com Inc. (Stealth Computer) a leading ISO 9001 manufacturer of industrial rugged computers and peripherals has released the new Model WPC-500F, a waterproof rugged, small footprint, fanless computer for environments where ordinary computer hardware won't survive.
The new Stealth WPC-500F is a rugged PC that is completely water-tight, surviving liquids, chemicals, dust and dirt intrusion, meeting IP67/NEMA 6 environmental specifications. Designed without cooling fans the internal CPU is cooled through advanced heat pipe technology. The rugged aluminum chassis also acts as a heat sink to dissipate internal heat and provide noise free operation.

Can America's Trains Go High-Speed?
The U.S. already has high-speed trains: the Acela Express has been carrying millions of riders between Washington, D.C., New York and Boston since 2000. It zips along at 150 miles per hour for relatively short distances—just over 25 miles per hour faster than conventional counterparts.
But compare it with high-speed trains in Europe and Asia that can reach speeds over 200 miles per hour on hundreds of miles of track. The problem is: tracks in the U.S. are not designed to support high-speed travel. Plus, any new express trains might have to share those lines with slower freight traffic.

NASA Tests Orion Seat Shock Absorbers
Engineers at NASA's Langley Research Center are using the Landing and Impact Research Facility to test the seat pallet that will protect astronauts in the planned Orion crew capsule from the shock of landing.
Requirements call for Orion to be able to parachute-land anywhere on Earth after returning from space, although the nominal spot would be in the Pacific Ocean off Catalina Island, Calif. To test the pallet and its "energy-absorbing struts," the 20,000-pound test article is dropped 18 feet onto a crushable honeycomb material designed to simulate different landing surfaces.

Lawmakers Fund Study Of Next Bomber
The decision by U.S. House defense overseers to authorize continued funding for Next Generation Bomber studies has buoyed the hopes of Senate bomber advocates, even though Defense Secretary Robert Gates wants to wait before spending more.
“We’re going to do everything we can to keep that program alive and keep it going,” said Sen. John Thune (S.D.), senior Republican on the Senate Armed Services airland subcommittee. Thune, whose state was a likely candidate for a long-range strike bomber base, has been a vocal critic of Gates’ plan to delay further research on the bomber. Gates has told lawmakers he wants to suspend related funding until after the Quadrennial Defense Review (QDR) and Nuclear Posture Review are completed.

NorthCom/NORAD Seeks Multirole Aircraft
The U.S. Air Force general in charge of U.S. Northern Command (NorthCom) says he needs multi-role aircraft to perform his varied missions, meaning the newest U.S. fighter is not necessarily the answer.
Those missions include maritime surveillance and air patrol and interdiction, Gen. Victor Renuart told Aviation Week after a speech last week on Capitol Hill. “Part of this air sovereignty mission is identification and non-kinetic enforcement. It’s diverting airplanes away. It’s identifying unknowns in our system. That doesn’t always require an F-22,” he said.

Chinese ASBM Development: Knowns and Unknowns
China wants to achieve the ability, or at minimum the appearance of the ability, to prevent a U.S. carrier strike group (CSG) from intervening in the event of a future Taiwan Strait crisis. China may be closer than ever to achieving this capability with land-based anti-ship homing ballistic missiles. There have been many Western reports that China is developing an anti-ship ballistic missile (ASBM). Increasingly, technical and operationally-focused discussions are found in a widening array of Chinese sources, some authoritative. These factors suggest that China may be close to fielding, testing, or employing an ASBM—a weapon that no other country possesses.

Russia Starts Tests for Strategic Nuke-Powered Sub
Russia's first submarine developed after the collapse of the Soviet Union, the strategic nuclear-powered Yury Dolgoruky, was launched on June 19 into the White Sea, where it will undergo 20 days of naval tests, the Russian government publication Rossiyskaya Gazeta reported June 23.
Yuri Dolgoruky is the first submarine of the Borei class (Project 955) that was being built for the Russian navy. Two more nuclear-powered submarines are being built at the Severodvinsk-based Sevmash plant where Dolgoruky was also produced.

Solar Impulse Is Revealed
An aircraft was unveiled Friday in Switzerland that aims to take off with one pilot aboard and fly day and night propelled only by solar energy, flying around the world without expending any fuel or expelling any pollution. The team led by Bertrand Piccard and Andre Borschberg believes the goal is unachievable "without pushing back the current technological limits in all fields."
