Postwar analysis placed the overall accuracy of daylight precision attacks with the Norden at about the same level as radar bombing efforts.
The 8th Air Force put 31.8% of its bombs within 300 meters (1,000 ft) from an average altitude of 6,400 meters (21,000 ft),
the 15th Air Force averaged 30.78% from 6,200 meters (20,500 ft), and
the 20th Air Force against Japan averaged 31% from 5,000 meters (16,500 ft).
Unable to obtain the Norden, the RAF continued development of their own designs. Having moved to night bombing, where visual accuracy was difficult under even the best conditions, they introduced the much simpler Mark XIV bomb sight. This was designed not for accuracy above all, but ease of use in operational conditions. In testing in 1944, it was found to offer a CEP of 270 meters (890 ft), about what the Norden was offering at that time. This led to a debate within the RAF whether to use their own tachometric design, the Stabilized Automatic Bomb Sight, or use the Mk. XIV on future bombers. The Mk. XIV ultimately served into the 1960s while the SABS faded from service as the Lancaster and Lincoln bombers fitted with it were retired.
