28th Operations Group The 28th Operations Group ( 28 OG ) is the flying component of the United States Air Force 28th Bomb Wing , stationed at Ellsworth Air Force Base , South Dakota . The 28 OG controls two B - 1B Lancer bomb squadrons , and provides combat - ready aircrews to project global power anytime in support of the Combatant Commander ' s objectives . The group carries the lineage and history of the World War II 28th Bombardment Group , which was one of the primary units assigned to Eleventh Air Force during the Aleutian Campaign . The group helped force the withdrawal of Japanese ships that attacked Dutch Harbor in June 1942 , and flew missions against Kiska until the Japanese evacuated that island in August 1943 . In the postwar era , the 28th Bombardment Group was one of the first USAAF units assigned to the Strategic Air Command on 4 August 1946 , prior to the establishment of the United States Air Force . The group being activated as a redesignation of the 449th Bombardment Group due to the Air Force ' s policy of retaining only low - numbered groups on active duty after the war . The group was inactivated in 1952 when the parent wing adopted the Tri - Deputate organization and assigned all of the groups squadrons directly to the wing . Reactivated as the 28th Operations Group in 1991 when the 28th Bomb Wing adopted the USAF Objective organization plan . Units . The 34th and the 37th Bomb Squadrons carry the legacy of the 1942 Doolittle Raid ers . The raiders were drawn from the 95th , 34th , 37th Bombardment Squadrons and the 89th Reconnaissance Squadron of the 17th Bombardment Group . History . World War II .

The group helped force the withdrawal of Japanese ships that attacked Dutch Harbor in June 1942 , flew missions against occupied Kiska until the Japanese evacuated that island in August 1943 , bombed and strafed enemy shipping , harbor facilities , canneries , fisheries , and military installations in the Kurils , and flew photographic reconnaissance missions . Earned a Distinguished Unit Citation for attacks on the Kurils that caused Japan to divert some of her air power to that northern area , weakening Japanese opposition to Allied forces to the south , April 1944 – August 1945 . Flew its last World War II bombing mission on 13 August 1945 , but continued reconnaissance operations in the Kurils into September 1945 . Inactivated in October 1945 , but activated a few months later in Nebraska . Received B - 29 Superfortress es and personnel from inactivated 449th Bombardment Group . Reassigned to Elmendorf AAF , Alaska for six months of post - war arctic operations in Alaska . Cold War . On 3 May 1947 , the group and its subordinate units relocated to Rapid City Army Air Field ( later Ellsworth AFB ) and awaited the activation of the new headquarters to which they would soon be assigned : the 28th Bombardment Wing . The 28th Bomb Wing was established on 28 July 1947 under the Hobson Plan , which was designed to streamline the peacetime forces after World War II . The wing existed only on paper until 15 August 1947 when SAC organized it under the 15th Air Force . Upon its activation , the wing included the 28 Bombardment Group ( Heavy ) , 28th Airdrome Group ( now Support Group ) , 28th Maintenance and Supply Group ( Now Logistics Group ) , 28th Station Medical Group , and the 612th Army Air Forces Band . On 12 July 1948 , in its first of many name changes , SAC activated the organization as the 28th Bombardment Wing , Medium . Just one week later , the wing deployed the entire 28th Bombardment Group and its 77th , 717th , and 718th Bombardment Squadrons ( BS ) to England for a 90 day B - 29 show - of - force mission during the Soviet blockade of Berlin . The wing flew the B - 29 until 1950 and maintained proficiency in heavy global bombardment . Shortly after additional runway improvements , in July 1949 , the 28 BMW began conversion from B - 29s to the RB - 36 Peacemaker . In April 1950 the Air Staff reassigned the base from 15th Air Force to 8th Air Force . With the change in aircraft also came a modified mission : global strategic reconnaissance with bombardment as a secondary tasking . The wing ’ s name changed again in April 1950 , this time to the 28th Strategic Reconnaissance Wing , Heavy . Meanwhile intermediate command assignments changed from the 15th to the 8th Air Force . In May 1951 the wing flew a record setting B - 36 training mission lasting 41 hours without refueling . In June 1952 , SAC inactivated the old 28th BG and assigned its squadrons directly under the 28 BW as part of the Tri - Deputate Organization .
