Naval aviation contributed importantly to UNC air operations from September 1952 to March 1953. On the first day of this period, three carriers staged the largest all-Navy Korean air strike to date, which simultaneously attacked an oil refinery at Aoji and other targets in the northeastern corner of Korea. Less than two weeks later, two carriers launched another assault in the same part of the country. The significance of these September strikes stemmed from the almost complete lack of enemy response. Apparently the Communists in this area had felt secure and protected, their territory being next to the Chinese border. In fact, their location close to the sanctuary had ruled out bombings proposed earlier. Strikes in this part of Korea were particularly suited to carrier planes of the Seventh Fleet, whose mobile airfields brought the targets within easy striking range along approaches that would not violate the Manchurian haven. Perhaps the greatest naval contribution to the air war were the Cherokee strikes, so named after the commander of the Seventh Fleet, Vice Admiral Joseph J. Clark, because of his Indian ancestry. This new type of deep air support attack, which came into use in October 1952, employed the maxim of mass delivery of ordnance. Usually, targets were immediately behind the enemy MLR but beyond the range of friendly artillery. In May 1952, when the rail interdiction program was being phased out and Admiral Clark’s pilots were faced with a decreasing number of prime industrial targets, the fleet commander had theorized that he could most effectually damage the enemy by bombing supply dumps, artillery positions, and reserve forces immediately to the rear of the Chinese MLR. As the admiral reasoned, the enemy could not fight the kind of war he was waging “and still have _all_ his forces, supplies, and equipment underground. _Some_ of his stocks of supplies had to be above ground, out of sight and out of range of our artillery.”[305] [305] Quoted in Cagle and Manson, _Sea War, Korea_, p. 461. Eighth Army welcomed the increased support that would result from the strikes, but FEAF expressed concern about the lack of top-level coordination. Admiral Clark had proposed that a EUSAK corps commander be allowed to authorize the attacks, which employed 24 to 36 aircraft. The Fifth Air Force initially maintained that it should control Cherokee strikes, just as it did the CAS missions. The matter was finally resolved in November.
