  • The Walleye was the first of a family of precision-guided munitions designed to hit targets with minimal collateral damage. This “smart bomb” had no propulsion system, but it could be maneuvered via a television assisted guidance system during its glide from an aircraft to the target. As a pilot dove towards a target, a television camera in the nose of the bomb transmitted images to a monitor in the cockpit. Once the pilot acquired a sharp image of the target on his screen, he designated an aim point and released the bomb, which would continue flying toward the designated target on its own. The bomb was a true fire-and-forget system because once launched, the plane could immediately turn away from the aim point. The Walleye maneuvered itself using four large fins. Later versions employed an extended range data link that let pilots keep flying the weapon after its release, and even change aim points during flight. The idea of a TV guided bomb came out of discussions between an eclectic group of civilian engineers at the Naval Ordnance Test Center (later the Naval Weapons Center) at China Lake, California. One of the engineers, Norman Kay, built televisions in his home as a hobby. Kay built an iconoscope camera in 1958 that could do a “funny thing,” recalled fellow project engineer William H. Woodworth. “It occurred to him that he could build a little circuit into there that would put a little blip in the picture, and he could make the little blip track things that would move in the picture.” The two engineers, soon joined by Dave Livingston, Jack Crawford, George Lewis, Larry Brown, Steve Brugler, Bob (Sam) Cunningham and several others, decided to research the idea further and quickly secured some seed money from the Navy to advance the concept. Adopting some technology from the AIM-9 Sidewinder air-to-air missile project and developing other components from scratch, the group developed the bomb in just four years. Among other revolutionary breakthroughs, the group developed the world’s first solid-state television camera with no vacuum tubes and the first zero-input-impedance amplifier. The team worked at nights and on weekends to keep the project on track and convince the Navy of its worth. Woodworth was the electronics expert and went so far as to take a year off from work and attend graduate school at his own expense to gain some additional theoretical knowledge needed for the project. Woodworth and Steve Brugler breadboarded the original tracking circuitry. Brugler then did the detailed analysis and design of the tracker for initial production. Larry Brown worked tirelessly to analyze the bomb’s flight traits, using an analog-computing instrument. Jack Crawford had an amazing “intuitive feel for physical phenomenon,” and could envision many of the flying traits of the bomb before it had even been built.
