U.S. Air Force General John M. Loh addresses the guests at the 13th Lockheed Technology Symposium held at the National Press Club in Washington, D.C. The theme of his address is that the Lockheed F-22 Advanced Tactical Fighter is critical in maintaining U.S. air superiority. As he points out, in the Gulf War we learned that the technology we had invested in for the last 20 years paid off. But we cannot stand still. It is essential that we continue to refine stealth technology and deploy enhanced capabilities in future weapon systems.

The technical challenge to evade radar began soon after radar was invented. One of the Lockheed F-117 Stealth Fighter's designers, Alan Brown, discusses the effects of shape, materials, and aerial maneuvers, among other factors, on an airplane's radar cross section -the key to measuring its vulnerability to hostile radar.

Helping explain why the F- 117 has a multi-faceted shape and the F-22 a smooth-surfaced one, a Lockheed senior R&D engineer, Dr. Vaughn Cable, describes the impact that improving computer technology has had on aircraft design capability. The ability to predict the radar cross section of vehicles has actually tracked closely with the evolution of the computer.

The Lockheed F- 117 program manager, Paul Martin, retraces the development of the "Have Blue" low-observable technology demonstrator aircraft of the late 1970s, the F- 117 development and production, and its success in Operation Desert Storm. Operational since 1983, the F-117 is being kept at the technology forefront through a planned weapon system improvement program

The special assignments director, systems engineering at Lockheed-Sanders, Gary Way, discusses the changing role of electronic warfare for stealth aircraft. Onboard sensors, including countermeasures, mission planning, and threat-warning systems, provide the pilot crystal-clear awareness of anything that could be either a threat or a target.

The Lockheed F-22 program manager, AI Pruden, describes how the Lockheed-Boeing-General Dynamics team met or exceeded all the Air Force requirements for the next-generation air-superiority fighter. From the beginning, the plan was to build a prototype that represented very high aerodynamic fidelity with the production aircraft, reducing the risk for engineering and manufacturing development and providing a high level of confidence to the Air Force.
