16th Air Expeditionary Wing The United States Air Force ' s 16th Air Expeditionary Wing ( 16 AEW ) was a provisional Air Expeditionary unit of the United States Air Forces in Europe from 1997 for the purpose of supporting US no - fly zone and other operations in the Balkans . It remained active until June 2003 , when it was replaced by the 401st Air Expeditionary Wing at Aviano . Units . The Wing was located at Aviano AB , Italy . It operated expeditionary sites at Camp Bondsteel , Kosovo ; Camp Able Sentry , Macedonia ; Sarajevo and Tuzla Air Base , Bosnia and Herzegovina ; Taszar Air Base , Hungary ; Zagreb , Croatia and Naval Air Station Sigonella and San Vito Air Station , Italy ; in addition to a contingency processing center at Rhein - Main AB , Germany . History . World War II . The unit was activated on 1 April 1944 at Dalhart AAF , Texas . Equipped with the Boeing B - 29B Superfortresses , the operational bomb squadrons were the 15th , 16th , 17th and 21st . The unit trained for combat initially at Dalhart , then moving to Fairmont AAF , Nebraska on 15 August 1944 . The B - 29B was a limited production aircraft , built solely by Bell - Atlanta . It had all but the tail defensive armament removed , since experience had shown that by 1944 the only significant Japanese fighter attacks were coming from the rear . The tail gun was aimed and fired automatically by the new AN / APG - 15B radar fire control system that detected the approaching enemy plane and made all the necessary calculations . The elimination of the turrets and the associated General Electric computerized gun system increased the top speed of the Superfortress to at and made the B - 29B suitable for fast , unescorted hit - and - run bombing raids and photographic missions . The 16th was assigned to Twentieth Air Force on 7 March 1945 and was deployed to Northwest Field , Guam as part of the 315th Bombardment Wing . Its B - 29s were marked with a Diamond - B tail code . The group entered combat on 16 June 1945 with a bombing raid against an airfield on Moen . Flew first mission against the Japanese home islands on 26 June 1945 and afterwards operated principally against the enemy ' s petroleum industry . Flying unescorted in the face of severe enemy attack , the 16th bombed the Maruzen Oil Refinery at Shimotsu on the night of 2 July ; the Mitsubishi refinery and Kawasaki oil installations at Kawasaki on the night of 12 – 13 July , and the coal liquefication plants at Ube on 22 – 23 July 1945 . The unit was awarded a Distinguished Unit Citation for the missions . There were several missions flown during the month of August and each resulted in the virtual destruction of an important Japanese petroleum refinery . The tactics of radar bombing from individual aircraft were used during attacks on the Mitsubishi - Hayama Petroleum Complex on the night of 1 – 2 August ; the Nippon Oil Refinery and Tank Farm at Amagasaki on 9 – 10 August , and the final target of the war for the 16th Group was the Nippon Oil Refinery at Tsuchizaki on 15 August 1945 . After the war the group dropped food and supplies to Allied prisoners gf war in Japan , Manchuria , and Korea , and participated in several show - of - force missions over Japan . The problem of dropping supplies to Prisoners of War was difficult . In the first place , most of the camps were small and hard to locate . Even more important was the great distance that had to be flown on some of the missions . Accurate information was lacking on several of the camps , especially those located in Manchuria and Korea . The Japanese had apparently shifted many of the prisoners around and closed down some of the concentration centers . Most of the supplies were dropped with the aid of a parachute but certain types of packages were permitted to fall free . The bombardier on each B - 29 had quite a problem in determining the exact moment of release . On 2 September , the 16th Group participated in the " Show of Force " mission over Tokyo which took place while the surrender terms were being signed on the battleship Missouri in Tokyo Bay . The mission was carefully planned as it represented the first attempt at formation flying that the organization had made since its arrival overseas . The aircraft flew over Tokyo Bay just as the surrender terms were signed and the men could watch the Missouri at the same time that they heard the broadcast of the ceremony over the radio . The B - 29s flew at approximately and could see clearly through a scattered undercast . The 16th Bombardment Group was inactivated on Guam on 15 April 1946 . From 1999 . The 16th Expeditionary Air Base Group was a redesignation of the 31st Air Base Squadron , assigned to Aviano Air Base , Italy in February 1999 . Its initial mission was a component of Operation Allied Force ( OAF ) , which was the NATO response to Serbian aggression against ethnic Albanian in Kosovo . In June 2003 the 401st Air Expeditionary Wing was reactivated at Aviano Air Base , Italy , replacing the 16th AEW , which inactivated to eliminate an overlap in heraldry with the 16th SOW at Hurlburt Field , Florida . The 16th AEW may have operated over Kosovo and elsewhere in southern Europe until 2005 – 2006 .
