Frank Bladin [SEP] World War II
On 17 June, under the command of Group Captain Clive Caldwell, No. 1 Fighter Wing recorded NWA's most successful interception to date, claiming fourteen Japanese raiders destroyed and ten damaged, for the loss of two Spitfires. The 380th Bombardment Group USAAF, consisting of four squadrons of Liberators, came under Bladin's control the same month, enhancing NWA's strategic strike capability. When Bladin handed over North-Western Area to Air Vice Marshal Adrian Cole in July 1943, the latter reported that his new command was "well organised, keen and in good shape".
