Raytheon's JLENS completes Demonstration Test One

TEWKSBURY, Mass., Feb. 17, 2012. Raytheon Company's (NYSE: RTN) Joint Land Attack Cruise Missile Defense Elevated Netted Sensor System (JLENS) recently completed Demonstration Test 1 (DT-1), proving its ability to track targets and integrate with fire control and tactical data link systems.

A series of demonstration tests were conducted at the Utah Training and Test Range from early November to mid-December 2011. The test included tracking moving ground and surface water targets.

The JLENS system communicates with targeting data over command and control systems, such as Link-16, and interfaces with combat identification support systems such as IFF (Identify Friend or Foe), to discriminate between friendly and hostile aircraft and missiles.

Providing a joint service capability, the JLENS system consists of two tethered 74-meter aerostats. One aerostat elevates a surveillance radar to 10,000 feet, providing coverage out for hundreds of miles over land and sea. The other aerostat elevates a fire-control radar. Each of the aerostat platforms has the capability to integrate other communications and sensor systems.

During live-fire tests later this year, JLENS will be tested on its ability to detect airborne threats and transmit targeting data to surface-based air and missile defense systems that will engage test targets. In the meantime, testing continues in Utah and at White Sands Missile Range, N.M.

Evolution of the American soldier

The American soldier has come a long way since the beginning of the Republic 237 years ago. While uniforms for early soldiers were based on cost and utility, soldiers' clothing eventually considered ballistic protection, increasing storage space, protection from poison gas and other contaminants.
