526th Intercontinental Ballistic Missile Systems Group The 526th Intercontinental Ballistic Missile Systems Group ( 526 ICBMG ) is an inactive United States Air Force ( USAF ) unit . It was last located at Hill AFB , Utah , where it was inactivated in 2010 . The group was first activated during World War II to conduct anti - submarine warfare in the Caribbean and off the Atlantic seaboard of Georgia and Florida . It was again active during the Cold War as an Atlas missile wing . Its final period of active service was as a systems and sustainment organization for USAF missile systems . History . World War II . The 526th ICBMG was first activated in 1942 as the 26th Antisubmarine Wing , a command organization for Army Air Forces Antisubmarine Command units in the Caribbean and South Atlantic . Its area of jurisdiction ranged from the Georgia / Florida border along the Atlantic Coast outward to approximately 100 miles eastward from coastline to the entire Gulf of Mexico , and Caribbean Sea from the Florida Straits south to the Venezuela coast . As the Army Air Forces turned responsibility for anti - submarine warfare over to the United States Navy in 1943 , the wing was transferred to First Air Force and disbanded while its squadrons were transferred and redesignated bombardment squadrons . Cold War . The 706th Strategic Missile Wing ( 706 SMW ) was established on 13 February 1958 at Francis E . Warren AFB , Wyoming . Preparation for intercontinental ballistic missile operations at F . E . Warren began on 15 January 1958 when Air Research and Development Command established the Strategic Missile Wing ( Provisional ) . On 1 February , Strategic Air Command took over F . E . Warren from Air Training Command and replaced the provisional wing with its Major Command controlled ( MAJCON ) 4320th Strategic Wing ( Missile ) . The 4320th was a support organization , and was assigned the 389th Air Base Group to act as the host for units at F . E . Warren . The 706th replaced the 4320th almost immediately , assuming control of the 389th . Two operational squadrons were activated later that year ; the 564th and 565th Strategic Missile Squadron s ( SMS ) . It accepted its first two SM - 65 Atlas missile complexes in August 1960 , gaining initial operational capability . The same year a third operational squadron , the 549th Strategic Missile Squadron was assigned The 706th SMW was replaced by the 389th Strategic Missile Wing ( ICBM - Atlas ) and inactivated on 1 July 1961 . The 389th assumed the 706th mission , equipment and personnel , except for th 549th SMS , which moved to Offutt AFB , Nebraska . Logistics Unit . The next iteration of the Wing was as the 526th Special Operations Wing . In 2007 , the wing was reduced to a group , and was made subordinate to the 508th Aerospace Sustainment Wing . The ICBM System Program Office ( SPO ) develops , acquires , and supports silo - based ICBMs and provides program direction and logistics support as the single face to the customer . The SPO is responsible for acquisition , systems engineering and depot repair support ; manages equipment spares ; provides storage and transportation ; and , accomplishes modifications and equipment replacement to maintain silo - based ICBM systems . The ICBM Prime Integration Contract ( PIC ) Program Management Office , LM ( 3 ) , is charged with day - to - day execution and management of the PIC . The office is accountable to the System Program Director ( SPD ) for cost , schedule , and technical performance of the ICBM prime contractor . LM ( 3 ) supports the other SPO divisions by working with LMK - P to translate requirements for engineering services and / or modification / replacement programs into the necessary contracting actions .
