Raytheon’s Electro-optical Technology in the Defense of Our Nation Part 1 of 2 Electro-optical Technology Features T his issue of technology today is dedicated to electro-optical (EO), infrared (IR) and laser technology in which Raytheon has a long and storied history in supporting the defense of our nation. As one of the world’s largest manufacturers of EO/IR sensors and systems — having delivered over 43,000 forward-looking IR (FLIR) systems alone — we have a lot to be proud of, but our greatest accomplishment is the difference we have made to our warfighters. While speaking at the 2002 DARPA Systems and Technology Symposium, General Richard Myers, chairman of the Joint Chiefs of Staff, stated that there are three technologies that have changed the nature of modern warfare: night vision, precision strike and global positioning systems. Two of these capabilities are provided by Raytheon’s EO technology and systems. Since there is so much to show and tell about EO, we have split the information into two issues of technology today. This edition shows how Raytheon has and continues to bring EO technology to support the defense of our nation. Here, we feature EO technology, our current products, and the enabling technologies on which they are based. The next issue of technology today will review emerging threats and the programs and enabling technologies that we are developing to address them. Figure 1 captures the breadth and depth of technologies that have given the warfighter affordable night vision to detect targets 4 2005 ISSUE 1 Figure 1. EO enabling technologies from the ground, the air and space. Once these targets have been detected, Raytheon laser ranging technology helps locate exacting target positions for our precision strike weapons. Once launched, Raytheon seekers guide our missiles accurately to these targets through either passive sensor tracking or semi-active or active illumination by Raytheon laser designators. However, the nature of warfare is evolving. In response, Raytheon continues to develop capabilities to sustain our charter of bringing EO technology to protect the warfighters and defend our nation. • Alan Silver asilver@raytheon.com In this issue, you’ll read about EO products and technologies. The next issue of technology today will focus on how we apply these technologies to emerging threats against our nation.
World Leadership in FLIR Systems Raytheon’s experience in designing, developing and integrating forward-looking infrared (FLIR) systems and subsystems spans space, airborne and ground combat systems. Over the past 40 years, Raytheon has successfully developed and fielded navigation, surveillance and targeting systems on numerous domestic and international programs. During this period, we have produced and delivered more than 43,000 FLIR systems. As one of the world’s largest manufacturers of electro-optical (EO) systems, Raytheon is known for its expertise and quality in this area. Space and Airborne Sensors Information gained from sensors in the air and in space has become a fundamental component in planning and forecasting a wide range of civil, military and intelligence activities. For years, advanced visible, infrared (IR) and microwave sensors have contributed to our ability to predict patterns and effects of weather. Such data can be of great value in planning anything from a picnic to a military campaign. Information developed by sensors in space allows forecasters to predict — among many other things — soil moisture content and weather patterns. This information might affect the number of ants you could expect at your picnic, but if you're a tank commander, it can also help you determine whether the mud on the battlefield is going to be too thick to plan a successful attack. The ability to predict sandstorms and their duration has already proven to be an important factor in Operation Iraqi Freedom (OIF). Data from polar-orbiting and geostationary platforms has been used for decades to support battlefield operations. The next 10 years will see improved environmental data from a new suite of National Polarorbiting Operational Environmental Satellite System instruments, along with revolutionary improvements in Geostationary Operational Environmental Satellite System weather products, courtesy of the new Advanced Baseline Imager and the Hyperspectral Environmental Suite of sensors. Currently, threat sensors such as the Defense Support Program provide missile warning. Soon, however, these sensors will be replaced by constellations of much more acute sensors in the Space-Based Infrared High and the Space Tracking Surveillance Systems. These systems will provide the target identification and tracking capabilities necessary to support the United States’ multilayered national missile defense program. Of course, we don't have to travel as far as space to encounter sensors operating with great strategic effect above the earth. Consider three recent stars of the sky: the Predator and Global Hawk unmanned aerial vehicles and Advanced Targeting FLIR (ATFLIR). • Predator, carrying organic sensors developed by Raytheon, has been conducting intelligence, surveillance and reconnaissance (ISR) operations in support of Operation Enduring Freedom (OEF) in Afghanistan. Raytheon’s precision strike weapons are then employed to engage threats as soon as possible. • Global Hawk also carries Raytheon EO and IR, and performed extremely well in ISR missions in OIF. Although it flew only three percent of air-breathing imagery intelligence missions and five percent of high-altitude reconnaissance sorties, it nonetheless accounted for 55% of the time-sensitive targets generated to kill air defense equipment. Global Hawk’s sensors located 13 surface-to-air missile (SAM) batteries, 50 SAM launchers, 300 SAM canisters, 70 SAM transporters and more than 300 Iraqi tanks. • ATFLIR is providing the F/A-18 Super Hornet with precision engagement with excellent standoff range. Moderate Resolution Imaging Spectroradiometer The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the NASA Terra and Aqua satellites provides daily global information on atmospheric, land and ocean environmental dynamics. Daily Continued on page 6 Figure 1. In this MODIS image taken March 28, 2003, dust is pooled in the valleys closest to the coast, while a front stretches across hundreds of miles. Into the waters of the Persian Gulf (center), bright blue swirls of sediment pour in from rivers. In places the swirls appear tinged with green, which suggests some marine plant life could be present.
