March 2, 2008 Like a lot of emerging science, the study of metamaterials is both amazingly cool and nearly impossible to understand without an advanced degree in physics or a long night on Wikipedia. It’s made Gizmag headlines before, with researchers claiming its unique structure, which has a negative refractive index, could be used to render objects invisible to the naked eye. Now scientists at Britannia Royal Navy College are working on a plan to use it to create the ultimate stealth vessel, according to a report in this month's edition of Physics World.  Read More

January 14, 2008 Lockheed Martin recently received final approval from the U.S. Navy to proceed with the integration and shipboard installation of the world’s first, fully-open architecture Aegis weapon system for a major surface warship. Aegis Open Architecture is a weapon system that can absorb frequent technology refreshes and upgrades in capabilities, both from new development and separate third party products.  Read More

Aegis Extended Range Missile

November 18, 2007 Raytheon's Standard Missile-3s have successfully intercepted and destroyed ballistic missiles outside the Earth’s atmosphere, the first time a Navy has ship demonstrated simultaneous engagements against such targets in space.  Read More

P-8A Poseidon anti-submarine aircraft

November 8, 2007 Boeing will have five P-8A Poseidon anti-submarine test planes completed by March 2009, with full production expected to commence in 2013. One hundred and twenty nine feet long aircraft with a 117 foot wingspan, the long-awaited replacement for the P-3 Orion will be incorporated into the US Navy and the Royal Australian Air Force. The Poseidon is a long-range anti-submarine plane like its predecessor, and will carry five torpedoes, four anti-ship missiles and two satellite guided bombs.  Read More

QinetiQ's Sentry - an unmanned surveillance vehicle on a jet-ski platform.

September 17, 2007 UK-based defense contractor QinetiQ is preparing to demonstrate the Sentry – an unmanned watercraft the size of a jet-ski that’s set up to perform remote-controlled patrol, reconnaissance and damage assessment missions. Its six hour mission endurance and control range of up to 16 nautical miles will make this stealthy vehicle a very practical security tool.  Read More

June 26, 2007 Both military and scientific missions stand to benefit from a new rapidly-deployable and autonomous mooring buoy system developed by Florida Atlantic University (FAU) and Lockheed Martin. Capable of being launched from air or sea, the system can self-moor in various bottom types - including sand, mud or rock - to depths of between 30 and 650 feet and has applications ranging from submarine detection to the collection of meteorological and oceanographic measurements.  Read More

Advanced Gun Systems aboard the Zumwalt Class Destroyer

June 21, 2007 The role of the Navy has changed with the U.S. "War on Terror" - it is seldom involved in direct naval battles and much more often relegated to support of invading (liberating?) land and air forces. Thus, munitions are being designed to suit. BAE Systems' Advanced Gun Systems (AGS) are currently under construction and will redefine the state of the art for naval firepower. The vertically loaded, pivoting gun towers will launch 155mm standard and guided munitions to a range of approximately 100 miles, with accuracy between 20 and 50 metres and at a rate of up to 12 rounds per minute.  Read More
