Pros and cons
Pros:
- Precision-guided bomb allows for greater flexibility on where to release weapon
- Once locked-on and released, the aircraft can begin egressing from the area
- Bomb can continue tracking moving visual targets upon release
Cons:
- Large size means only a few can be carried by aircraft
- Limited effectiveness in night conditions, since it's TV-guided
- TV-guided camera views from the aircraft's frontal arc, requires pointing the aircraft at the general location of the enemy to begin targeting

The Walleye's genesis came about thanks to a TV-loving NAS China Lake engineer named Norman Kay. In his spare time, Kay enjoyed creating television sets, and in 1958, he developed a camera that could follow and trace moving items in a picture by using a "blip" that it could project. By using a piece of circuit-board, Kay had just created the first device capable of tracking moving objects by using the difference in contrast between said item and the background. Later refinements would follow, and with a team of fellow engineers including Jack Crawford, Dave Livingston, George Lewis, Larry Brown, Steve Brugler, Bob Cunningham and long-time friend William H. Woodworth, would engineer the bomb that would eventually become Walleye. Among other challenges that they faced and defeated were refining the bomb's trajectory, eliminating the use of vacuum tubes in order to both simplify production and to ensure that the bomb was capable of making the turns and twists needed by a guided weapon, and withstand the shock of carrier catapult takeoffs, and the dilemma of procuring funding- initially by wheedling funding away from the AIM-9 Sidewinder project, which was concurrent to the tv seeker's development. By 1963, the development of the bomb had become official, and after a period of competition between various firms, Martin-Marietta won the contract in 1966 for full-rate production.
The AGM-62 was engineered to have a link between the seeker and a small TV monitor in the launch aircraft's cockpit, which is what would be used to select the target for the seeker. In the words of one of the engineers- the seeker "wasn't smart enough" to know that "a bridge was a bridge", but it could use the contrast between the bridge and whatever surrounded it and home in on the patch of contrast differential. Proposed features for the first iteraton included a datalink, which would not be integrated on initial Walleye I variants. However, the camera could still be used to see where the bomb was going, which would be important for allowing fire-and-forget capability. Pilots could now drop a bomb and then immediately turn away from the target, monitoring the bomb's progress, and once the data-link ability was integrated, provide course corrections for the bomb.
Walleye I used a thousand-pound warhead from the Mark 83 1000 pound General-Purpose bomb, recently developed in the 1950s in response to the need for lower-drag bombs. The unit was initially powered by a heavy set of lithium-ion batteries, but these were soon replaced by a ram air turbine on the back of the bomb, giving it the distinctively large propellor, different from propellor-driven tail and nose fuzes on older GP bombs like the AN-M65A1 that its predecessors had used. Large, triangular fins driven by hydraulic actuators were attached onto the rear, allowing the bomb to move left and right, and stabilize on the target. The seeker was the first-ever fully solid-state TV camera in existence. The bomb was meant to incorporate a revolutionary new data-link feature to allow the pilot to aim and steer the bomb while in flight, but tihs feature was temporarily dropped due to time constraints. Later versions of the bomb would reincorporate this feature into the bomb, allowing mid-flight course corrections. The bombs would find great success in Vietnam, chalking up successful missions such as the final destruction of the infamous Thanh Hoa Bridge and several successful missions against power plants, including a raid that destroyed Hanoi's main source of power a mere two days after Ho Chi Minh's birthday. The bomb would continue to be used, including with the data-link upgrade, during the Gulf War in 1991, after which it was gradually retired from US Navy and Air Force service as newer warshots, such as the GBU-15, AGM-65, JDAM and improved Paveway Variants came into service, and improved targeting pods allowed for laser-guided bombs to be more easily guided onto target.
