The lurker bomb that can hover for ten hours... and then strike its target in the space of a minute

By Peter Almond

A revolutionary missile that can stalk a target until the perfect moment to strike is being developed by the Ministry of Defence for use against the Taliban in Afghanistan.

The so-called lurker bomb will also be able to shadow British troops for up to ten hours or 100 miles, ready to take out enemy targets with surgical precision at a minute’s notice.

The 12ft weapon – officially named Fire Shadow and made in Britain by leading missile manufacturer MBDA – will be operated by the Royal Artillery.

It made its first test flight in Wales earlier this year and is expected to be operational by 2010.

One of the biggest problems facing British troops in Afghanistan is Taliban ambushes. The insurgents often escape before a counter-attack can be launched because they know the Afghan terrain well, it takes time for air support to arrive, and the British are reluctant to use existing powerful missiles for fear of causing collateral damage such as killing civilians or flattening homes.

Fire Shadow’s ability to ‘stooge’ above the troops means it can be guided to a target within seconds. And its deadly precision requires only a small warhead of 50lb, compared with the RAF’s smallest bomb of 500lb.

The Army wants to be able to fire salvos of Fire Shadows, having several in the air at once to hit multiple targets. The missiles, also known as ‘loitering munitions’, are expected to replace some RAF patrols.

Fire Shadow can be guided to its target by troops on the ground with lasers, by operators in aircraft or helicopters, or by the Army’s new Watchkeeper surveillance drone.

Lurker bomb: The 12ft Fire Shadow missile can be launched up to 100 miles away from its target

Once airborne, however, Fire Shadow is unable to return to base. If it is not used in action, it is brought down in a controlled crash after it runs out of fuel.

Akram Ghulam, head of loitering munitions at MBDA in Stevenage, Hertfordshire, said: ‘I can see these being used where small, surgically precise effects will have greater utility than an artillery shell or a bomb.’

MBDA leads the Fire Shadow development team, which cost the MoD £74million in its first year. It includes British firms Qinetiq, Thales and Roxcel, and several smaller and academic organisations.

The concept of a lurker bomb is the cornerstone of the MoD’s Indirect-Fire Precision Attack project. Fire Shadow is one of six projects that include an artillery shell that can electronically ‘sense’ its target, a new anti-aircraft missile for the Royal Navy, and advanced guidance for the new Guided Multiple Launch Rocket System (GMLRS).

The first GMLRS batteries have already been in action in Afghanistan’s Helmand area where British troops are operating. Nicknamed the 70km sniper – the rocket’s maximum range – about 250 precision-guided rockets have been fired so far this year, according to an MoD spokesman. At £60,000 a rocket that works out at £15million, a cost that the MoD is well aware of as it seeks to develop Fire Shadow.

‘We need to get Fire Shadow’s price to around that, which is a big challenge,’ said an industry source.

Sticky Substance Could Turn You Into Spider-Man

Peter Parker needed a radioactive spider bite to be able to climb walls. And Mohinder Suresh joined the wall-climber club after downing his superpower formula, and we all know that doesn’t end well. So, rather than have us expose ourselves to unpredictable mutations, a pair of researchers have developed a material that will let you let you stick to the ceiling without the unfortunate side effects.

Liming Dai of the University of Dayton and Zhong Lin Wang of the Georgia Institute of Technology reported that they have developed a super Post-It material that can come unstuck with a deliberate tug, but is 10 times stickier than the feet of some geckos and lizards:

Liming Dai and Zhong Lin Wang said that they developed their artificial setae by growing nested carbon nanotubes on a silicon wafer. The researchers controlled the growth process to make a forest of vertical nanotube trunks turning into a canopy of tangled ends on top. The curly entangled mess acted like natural spatulae: when pressed against a surface, they had a large contact area and hence a strong hold.

The group tested the new material for stickiness on surfaces ranging from Teflon to sandpaper. It was found that when attached to a glass surface, a single square centimetre of it could support 1600g when pulled roughly parallel to the surface, three times better than the best artificial competitor.

No word yet as to whether the researchers have tested it by attempting to scale a skyscraper.

Navy charters kite-powered cargo ship to deliver equipment

Posted by Mark Rutherford


For the first time, the US Navy is using a new breed of sailing ship to deliver military equipment, a move that can potentially reduce fuel costs by 20 to 30 percent, or roughly $1,600 a day per ship, according to the ship's owners.

The Navy's Military Sealift Command (MSC) has chartered the "kite-assisted", fuel-saving 400 foot, MV Beluga to deliver Air Force and Army cargo to from Europe to the US.

The MV Beluga uses a paraglider-shaped, SkySails-System, which supplements its conventional, internal combustion engines. The sail is basically a huge, computer-controlled kite that soars 100 to 300 yards into the air, using the wind to tow the ship at the end of a long tear-proof, synthetic rope.

The SkySails System is operated by the crew from a workstation on the bridge. All the steering and flight path adjustments are done automatically. "Emergency actions" are taken care of with a "push of a button." But the SkySail is only deployed offshore, outside the three-mile zone and traffic separation areas--just in case.

Unlike conventional sails, the kite has no superstructures that can get in the way of loading and unloading dockside, or scrape the bottom side of bridges as it sails under. The kite folds up, and can be stowed in an area the size of a telephone booth, according to developer SkySails GmbH & Co. KG of Hamburg, Germany. And, the SkySail can "generate two to three times more power per square meter sail area than conventional sails," according to the company. The environmental benefits have yet to calculated.

Though wind power was not a factor in awarding the contract, the shipping company was likely "able to capitalize on fuel savings to make its offer more competitive," according to MSC. "MSC values innovation that leads to cost savings," said Captain Nick Holman, of Sealift Logistics Command Europe.
