The actual performance of the Norden in combat was good some of the time, but rarely great, and often terrible. Several studies revealed that as few as 5 percent of Eighth Air Force bombs fell within 1,000 feet of the target and the average error for 500-pound bombs dropped in Europe was a whopping 1,673 feet.
Who invented precision bombing?
The term may have been coined by Norden’s Barth, who was among its most energetic popularizers. Norden was not alone in spreading the legend. Some Air Force bombardiers spoke proudly of tossing bombs into a 100-foot circle from four miles up.

“What did the Norden Bombsight do? It allowed you to bomb only those things which you absolutely needed and wanted to bomb.” The Norden, essentially an analog calculator, could adjust for air density, wind drift, the bombers airspeed and groundspeed while controlling the bombers’ final run on the target.

Early work. The Norden sight was designed by Carl Norden, a Dutch engineer educated in Switzerland who emigrated to the U.S. in 1904. In 1911, Norden joined Sperry Gyroscope to work on ship gyrostabilizers, and then moved to work directly for the U.S. Navy as a consultant.
