If By Sea

Keeping your boat's bottom shipshape

The U.S. Navy may have developed a solution to hull-dwelling barnacles and slime--a "foul" problem that has plagued sailors and their ships since Noah launched the ark.

The Office of Naval Research (ONR) has developed what looks like a combination pressure washer/minisub called the Hull Bio-inspired Underwater Grooming, or Hull BUG. It's designed to prevent or suppress the growth and build-up of nuisance marine growths such as barnacles--also known as biofouling (PDF).

This could be a major breakthrough. High-performance warships and submarines rely on a clean hull for speedy acceleration and hydroacoustic stealth--things that crustaceans … Read more

Avoid sinking feeling with bulletproof lifejacket

Here's a must-have accessory for any soiree off Somalia, the ArmourFloat personal flotation device.

Not only does the Armour Float Ballistic Vest keep even an unconscious wearer afloat, but its new lightweight, hard-plate armor is designed to defeat most assault rifle threats--with no negative effect on the vest's buoyancy, according to Armour of America, a division of Arotech Corporation.

This Underwriters Laboratory-certified PFD is approved by the US Coast Guard, and the Coasties use it as well, according to AoA.

The hardy preserver comes with reflective tape on the shoulders, an emergency strobe light pocket, ammo clip pockets, … Read more

World awaits ballistic-missile takedown over Asia

Does a "Star Wars" missile defense work? We may soon find out, if the rocket launch planned by North Korea starts to veer anywhere near Japan, instead of disappearing harmlessly into the stratosphere, as is hoped.

Japan says it will station the destroyers Kongo and Chokai in the Sea of Japan off North Korea. Both vessels will be armed with SM-3 ballistic-missile defense systems, in case the rocket malfunctions or wanders close to any of its islands, according to the Japanese Kyodo news agency.

"If it is capable of reaching Japan, then it goes without saying that … Read more

Royal Navy goes with 'Windows for Subs'

Bucking the open-source trend, the British Royal Navy has developed a modified version of Microsoft Windows XP and has begun installing it on its fleet of nuclear submarines.

The new Submarine Command System Next Generation (SMCS NG) employs standard multifunction consoles with double LCD screens, linked with "commercial grade" cables and software to internal Ethernet local area networks (LANs) aboard each sub.

Ever thrifty, the spit-and-baling-wire Brits went with Windows in part because it was cheaper to maintain. The use of commercial off-the-shelf technology is expected to save the U.K. taxpayers up to $32 million over the … Read more

Submersible airplane, another DARPA 'must have'

The Defense Advanced Research Projects Agency's (DARPA) Strategic Technology Office is looking for a submersible aircraft design and invites you to come up with a concept.

Performance requirements call for an aircraft that can cover 1,850km by air or 185km by sea, or 22km underwater in eight hours or less. And this is not some miniature pool hopper; DARPA wants it to be able to carry a crew of eight and a 2,000lb payload.

Speculation on design suggests an old-school snorkel to provide air supply for the power plant while your flying fish is in submerged mode, … Read more

Rugged notebook from the house of salt and fog

It happens every time. The mainsail cover is off, and it's freshening nicely. Then the boss calls begging you to get online and placate one of her key accounts. Luckily, she's seen fit to spring for the fully salt/fog-certified B300 ruggedized notebook.

What distinguishes this rugged, watertight, vibration- and drop-shock resistant PC--besides the sealed ports and connector cover--is the finish. According to manufacturer Getac, it protects everything from hinges to the keyboard to the electrical innards from salty corrosion, thus allowing you to telecommute from deck to dune.

The B300 was recently certified under standards set by … Read more

Anti-swimmer system bad news for frogmen

You can't really say you have a private beach until you've installed a SM 2000 Underwater Surveillance System by Kongsberg to keep out the riffraff.

The system is designed to protect commercial piers, government and military vessels, cruise ships, terminals, and other high-value assets, but it'll work just as well for your hideaway surf break. You know it's good if the oil sheiks buy it. Kongsberg installed an integrated system at a "High-Value Seaside resort" in the United Arab Emirates; the exact location is classified.

The U.S. Coast Guard just picked up $2 … Read more

Robo-fish may monitor future oil spills

Propelled by a servo-actuated two-link tails and flapping pectoral fins, a new breed of robofish programmed to swim in schools may soon be used to track oil spills or wildlife such as whales, according to researchers at the University of Washington in Seattle.

By mimicking a fish's natural propulsion mechanics these "autonomous fin-actuated underwater vehicles" are able to swim in any direction, make tight turns, and even go backwards, researchers say. The university is testing three of the vehicles in an indoor freshwater tank equipped with a four-camera tracking system to supplement data collected by onboard sensors.… Read more

Military awards contract for next-generation tactical radio system

The Pentagon has awarded defense heavyweight Lockheed Martin the contract for next-stage development of the Joint Tactical Radio System (JTRS), a new-generation radio technology that will replace dozens of legacy systems throughout the U.S. military (PDF).

Initial design and development costs for this phase, called Airborne Maritime and Fixed Station, will run $800 million to $1.2 billion, with a potential $10 billion more for full production later. Boeing and Lockheed Martin worked on separate preliminary designs for the new programmable, tactical radio system, but only Lockheed nailed the contract.

The Department of Defense initiated the JTRS program in … Read more

Navy buttons-up new working uniform

Here's the new Navy enlisted, BDU-style uniform as displayed at the Defense Logistic Agency exhibit booth, Armed Forces Communications and Electronics Association West 2008 (AFCEA) conference in sunny San Diego, CA.

The new Navy Working Uniform (NWU) will include several cold weather options, such as a unisex pullover sweater, a fleece jacket, and a parka. It comes in three camo patterns, the main one being the blue/gray variant you see here, with woodland and desert digital palette for those going ashore.

The permanent press, 50/50 nylon and cotton blend NWU will replace seven different styles of currentRead more
