Shock Wave Explosion

Defence Research and Development Canada (DRDC) has captured the shock wave of an explosives test at their experimental proving ground, a piece of land that measures over 470 square kilometers."The photo gives an unusually clear look at the shock wave that accompanies the explosion, distorting the view around the fireball as it travels outward," says iO9.

F-22 Raptor

Lockheed Martin's F-22 Raptor conducted its first flight in 1997, and is a single-seat, twin-engine, all weather stealth tactical fighter aircraft developed for the U.S. Air Force (USAF). It was initially designed primarily as an air superiority fighter, but has additional capabilities including ground attack, electronic warfare, and signals intelligence roles. While Lockheed Martin is the prime contractor, Boeing provides the wings, aft fuselage, avionics integration, and training systems. The flyaway cost for a single unit is $150-million, as of 2009.

B-2 Stealth Bomber

At $2.1-billion (fly away cost) per unit, the B-2 Spirit stealth bomber, developed and manufactured by Northrop Grumman, is basically a heavy strategic bomber that features low observable stealth technology designed for penetrating dense anti-aircraft defenses; it is able to deploy both conventional and thermonuclear weapons. It has a crew of two and can drop up to eighty 500 lb (230 kg)-class (Mk 82) JDAM Global Positioning System-guided bombs, or sixteen 2,400-pounds (1,100-kilograms) B83 nuclear bombs. The B-2 is the only known aircraft that can carry large air-to-surface standoff weapons in a stealth configuration. Continue reading for more.

Lockheed Martin Adam

Lockheed Martin's new 30-kilowatt fiber laser called Athena managed to burn through a truck manifold in seconds, despite being fired by a team from Lockheed Martin positioned more than a mile away. The system uses a technique known as spectral beam combining to blend multiple laser modules to create a single, powerful, high-quality beam. This is done for greater 'efficiency and lethality' than the multiple individual 10-kilowatt lasers used in other systems. Continue reading for two videos and more information.

SR-71 Factory

Here are some rarely seen pictures show how engineers in 1960s California secretly developed the SR-71 Blackbird for the US Air Force, currently still the fastest unclassified aircraft. These rarely seen once classified photos reveal how Lockheed built three types of Blackbird - A, B and C in Burbank, California. All of the SR-71 models were built by American aerospace company Lockheed under a 'black project'. The SR-71 Blackbird has held the world record for the fastest air-breathing manned aircraft with a record speed of 2,193.2mph, since July 28, 1976. To withstand the high temperatures generated by friction due to sustained Mach 3 flight in the upper atmosphere, the SR-71 required an array of specially developed materials including high temperature fuel, sealants, lubricants, wiring and other components.

Soft Armour

Soft Armour is no ordinary bulletproof wall, as it's filled with ceramic balls. While it sounds like nothing special, it's designed to stop bullets from penetrating and ricocheting the wall. According to its creators, "Saab's Soft Armour system offers protection against ballistic penetration up to NATO 7.62 mm AP ammunition (STANAG level III). The system is a box concept filled with hard ceramic balls. The system is especially designed to enhance survivability and can be fitted to any structure prior to missions, or even retrofitted to existing structures in operational theatre."

Lockheed Martin Experimental

For just $180000 USD, you could be the lucky owner of the HSV Sea Slice, an experimental United States Navy vessel, built by Lockheed Martin. Based on a variant of the SWATH hull design, known as "SLICE," Sea Slice is characterized by four teardrop-shaped submerged hulls - double the number seen on most previous designs. According to the US Navy, the design reduces waves and drag, which allows a SWATH vessel to "...operate at higher speeds while retaining their characteristic low motions in a seaway".

US Navy Railgun

For the first time in history, the US Navy will publicly demonstrate their crazy railgun at the Naval Future Force Science and Technology Expo in Washington D.C. on February 4. The U.S. Navy plans to integrate a railgun that has a range of over 160 km (100 mi) onto a ship by 2016. By that time the Navy expects to have a weapon that can fire multiple projectiles per minute. The hyper-velocity rounds weigh 10 kg (23 lb) and cost about $25,000 each. Continue reading for a video and more information.

F-35 Weapons

Lockheed Martin has just released a new picture showing the sleek F-35 Lightning II with all of the weapons it can use after being tested by the Systems Development and Demonstration Weapons Suite. According to Jalopnik, "This represents a baseline capability that will be expanded with other weapons once the jet is fully operational towards the end of the decade."

JSF Helmet

Did you know that the F-35 does not need to be physically pointing at its target for weapons to be successful? It uses sensors to track and target a nearby aircraft from any orientation and then provide the information to the pilot through their helmet for complete vision - also sends data to the seeker-head of a missile for accurate targeting. The helmet system replaces the display-suite-mounted head-up display used in earlier fighters. The F-35's systems provide the edge in the "observe, orient, decide, and act" OODA loop; stealth and advanced sensors aid in observation, automated target tracking helps in orientation, sensor fusion simplifies decision making, and the aircraft's controls allow the pilot to keep their focus on the targets, rather than the controls of their aircraft.
