the monitor news The Journal of Electronic Defense | July 2009 USAF STAND-IN JAMMER PROGRESSES The US Air Force reported last month that Raytheon’s Miniature Air-Launched Decoy-Jammer (MALD-J) program had successfully completed its Preliminary Design Review milestone. MALD-J adds a radar-jamming payload to the basic MALD, a cruise missile-like, turbojet-powered, expendable maneuvering decoy with a range of 500 nautical miles. MALD is in low-rate production at Raytheon Missile Systems (Tucson, AZ) and is slated to become operational this fall. The service’s MALD program manager at Eglin AFB, FL, Ken Watson, said he had cleared the MALD-J program to proceed with final design activities and prepare for a Critical Design Review by early next year. MALD-J recently completed captive-carry testing, he said. Raytheon will conduct a free-flight demonstration later this year and begin engineering and manufacturing development in 2010. A production decision is planned in early 2011, Watson said. MALD-J will provide “stand-in” jamming close to enemy air defenses. Harry Schulte, vice president for air warfare systems at Raytheon Missile Systems (Tucson, AZ), told reporters at the Paris Air Show on June 15 that the UK is interested in acquiring the basic MALD vehicle, dubbed MALV. He said the US and UK governments had recently signed a technical assistance agreement for a MALD demonstration, and that Raytheon had been cleared to talk to British defense officials about the MALV. Under this agreement, the UK would integrate its own payloads into the MALV – G. Goodman 15 NEW US BACKPACK IED JAMMER Sierra Nevada Corp. (Sparks, NV) emerged last month as the winner of a three-company competition to manufacture new Joint Counter Radio-Controlled Improvised Explosive Device Electronic Warfare (JCREW) 3.1 dismounted backpack jammers for the US military services. Naval Sea Systems Command (NAVSEA) awarded the company an initial $36.5 million contract for 200 of its Thor III systems, with options for an additional 2,300 that could bring the contract’s cumulative value to $248.3 million. Sierra Nevada, ITT Advanced Engineering and Sciences (Annapolis Junction, MD) and Northrop Grumman Mission Systems (San Diego, CA) had each been awarded a contract in December 2007 to provide seven off-the-shelf JCREW 3.1 engineering prototypes for test and evaluation. (ITT, Northrop Grumman and SRCTec of Syracuse, NY, are competing for a separate five-year NAVSEA contract to supply up to 5,000 new JCREW 3.2 vehicle-mounted jammers.) The vast preponderance of the jamming systems that have been in use by US Army and Marine Corps units in Iraq and Afghanistan are vehicle-mounted. The US military has fielded far fewer man-portable counter-IED systems for dismounted soldiers, particularly due to the demanding size, weight and power requirements of those systems. They must be much smaller and lighter than vehicle-mounted systems, while including a battery pack for power and an antenna. They also must provide an effective level of jamming performance – as many watts as possible – without endangering the safety of the soldier carrying the system from the emitted radiation. Vehicle-mounted systems are less constrained by size and weight compared with dismounted systems, and they draw on the vehicle’s power instead of batteries to achieve greater jamming power and range. While man-portable systems are typically carried in a backpack, the first to be deployed in Iraq in August 2005 was actually a hand-held system called Warrior Blue, which resembled a “walkie-talkie” radio. Produced by northern California-based Tyco Electronics, the portable jammer was used by infantrymen on foot patrols or at checkpoints. However, the half-watt system quickly became obsolete, because it was designed to counter a low-power radio threat and insurgent bomb makers soon moved to more powerful radio triggers. The device also used eight lithium batteries, which required frequent replacement.
