close to the Alaskan coast, but in international airspace. Two F-102s, dispatched from Galena, intercepted two Tupolev Tu-16E or F "Badger" jet bombers just at the edge of their effective range. It was also found that the F-102 proved unequal to the task of intercepting other Soviet reconnaissance aircraft due to their limited range. In March 1963, a Soviet reconnaissance bomber overflew Nunivak Island and the west coast of Alaska. Two F-102s were scrambled from King Salmon but the pilots had to be recalled because of low fuel when they were within 20 miles of the Soviet aircraft. This led to a serious debate about AAC's capabilities and the decision to replace the F-102s with the Convair F-106 Delta Dart from Air Defense Command. The first eight F-106s temporarily deployed from ADC arrived at King Salmon and Galena Airports in July 1963. In September, the F-106s succeeded in intercepting two TU-16s over the Bering Sea. Production, however, of the F-106 had ended in 1961, and Air Defense Command had none to send to Alaska. In late 1961, Kennedy's Secretary of Defense Robert S. McNamara spoke of reopening the F-106 production line to build another 36 aircraft. However, ADC had heard so much about the capabilities of the Navy's F4H-1 Phantom two-seat interceptor that it thought that it might be a better idea to purchase some F4H-1s rather than buy additional F-106s. Instead, ADC chose to begin rotational deployments of the F-106 to Elmendorf AFB and onto Galena and King Salmon for alert duty. That arrangement continued until 1970, when the F-4E Phantom II arrived at Elmendorf. Radar Surveillance Under Eleventh Air Force, a radar system was set up to warn of Japanese attacks which stretched from Point Barrow to Shemya, however it was dismantled after the end of the war. With the breakout of the Cold War, plans were made by Alaskan Air Command to establish a new system for air defense. Discussions ensued and several plans were proposed and modified, until in 1948 a plan was agreed on and funded by Congress in 1949 for ten radar sites for Alaska. Early-warning radars would be located at Elmendorf AFB, Ladd AFB, King Salmon and Gambrell on St. Lawrence Island. These radars would alert the interceptors of the 57th Fighter Group at Elmendorf, with radars north of the Alaska Range alerting the 449th Fighter Squadron at Ladd AFB. By 1950, planners
