The squadron was equipped with F - 47D Thunderbolt s and was assigned to the 112th Fighter Group . Air Defense . The 146th Fighter Squadron ' s mission was air defense over Pittsburgh and western Pennsylvania . Not activated during the Korean War , the squadron retired its F - 47s in 1951 was re - equipped with long - distance F - 51H Mustang interceptors , due to the lack of jets which were being used in Korea . After the Korean War ended , originally it was planned to convert the 146th FBS from its propeller - driven F - 51Hs to F - 86A Sabre jet daylight interceptors , but after receiving four Sabres , the squadron began to receive new F - 84F Thunderstreak s in October 1954 . In December 1957 , the 146th replaced their F - 84Fs with all - weather F - 86D Sabre Interceptors . Beginning in 1960 , Air Defense Command upgraded the 112th Fighter Interceptor Group to the supersonic F - 102A Delta Dagger interceptor . Squadron pilots stood runway alert for 24 hours a day , seven days a week at the Greater Pittsburgh Airport ready to scramble regardless of the weather conditions to intercept any unidentified aircraft approaching southward from the Canadian border or toward the United States from the Atlantic Coast , their F - 102A Delta Daggers fully armed with two heat seeking missiles and four radar guided missiles as well as 2 . 75 inch rockets . Tactical Air Command . With air defense becoming less critical , in 1975 the 146th ended its air defense mission , receiving its first A - 7D Corsair II aircraft and was reassigned to the Tactical Air Command . The principal mission of the squadron became the destruction of ground targets in support of ground forces . The A - 7Ds were initially received from the 354th and 355th Tactical Fighter Wing s , which were being upgraded with new A - 10A Thunderbolt II aircraft . Beginning in 1976 and 1977 , new A - 7Ds were received directly from the manufacturer , and in 1980 , the squadron received some A - 7K two - seat trainers . Air Refueling . By the end of the 1980s the A - 7Ds were being retired from the Air Force inventory , and in 1991 the 146th traded in its ground support fighters and the 112th was transferred to Strategic Air Command , becoming a KC - 135 Stratotanker air refueling squadron . The 146th has continued this mission into the present - day . The tankers were operated jointly with the 147th ARS at Pittsburgh , its parent unit , the 171st Air Refueling Wing , had become an air refueling organization in October 1972 . Strategic Air Command was inactivated in June 1992 and the 112th ARG became a part of the Air Combat Command ( ACC ) . On 1 October 1993 , with both the 112th Air Refueling Group and the 171st Air Refueling Wing at Pittsburgh , the two tanker units were consolidated with the 146th Air Refueling Squadron being reassigned to the 171st Operations Group and once again reuniting with the 147th under the same group . The 112th Air Refueling Group was inactivated . With the consolidation , The 171st ARW consisted of 16 aircraft assigned to two squadrons , making it one of only three Super Tanker Wings within the Air National Guard . Post Cold War era . In May 1999 , the 171st activated over 500 members and fourteen aircraft to Budapest , Hungary and Frankfurt , Germany , in support of Operation Allied Force deterring ethnic aggression in Yugoslavia . The 146th became part of the 171st Expeditionary Operations Group that flew 411 sorties and refueled 2 , 157 receivers . All members returned home by the beginning of July 1999 . In November 2000 , the 171st deployed 228 personnel to Istres AB , France in support of Operation Joint Forge , a NATO - led stabilization mission in Bosnia - Herzegovina . During this deployment the crews flew 51 sorties in seven of our KC - 135s , and offloaded 1 . 4 million pounds of fuel . Global War on Terrorism . the 171st found itself among the first units called to duty almost immediately after the 9 / 11 terrorist attacks in New York City , Washington D . C . and in its own backyard in southwestern Pennsylvania on September 11 , 2001 with the hijacking and crash of United Airlines Flight 93 . At the time , almost all of the Wing ' s aircraft were in a stand - down mode , while nearly all of its assigned aircraft were being converted to with the new Pacer - Crag cockpit and navigation upgrade . Within minutes of the first aircraft crashes , the 171st Air Refueling Wing was airborne with its only flyable KC - 135E . Its mission was to provide aerial refueling to the fuel - thirsty jet fighter aircraft that were providing Combat Air Patrol s ( CAPs ) over the skies of the eastern United States as part of Operation Noble Eagle ( ONE ) . On the ground back in Pittsburgh , the maintainers and aircrews made more aircraft airworthy and then keeping them flying . Almost seamlessly , the 171st went into a wartime footing . Within 24 hours after the first attacks , the 171st was flying round - the - clock CAPs support sorties with eight Fully Mission Capable KC - 135s . Before the continuous CAP missions were ended in early 2002 , more than 13 , 000 combat missions were flown over U . S . soil . During the first decade of the 2000s , the 171st was engaged in combat operations in supporting Operation Enduring Freedom , Operation Noble Eagle , Operation Iraqi Freedom , deployed to Guam , participated in the Hurricane Katrina Relief Effort , supported numerous Raven assignments , supported our AEF cycles and other missions . In an effort to support the international response to the unrest in Libya and enforcement of United Nations Security Council Resolution 1973 of a no - fly zone over Libya , the 313th Air Expeditionary Wing , with the 171st as the lead unit , was stood up in March 2011 by a blend of active duty , guard and reserve airmen . A total of 1500 sorties , 11000 flying hours , and 70 million pounds of fuel transferred aircraft from more than ten countries was accomplished by this citizen - airmen volunteer milita force . Initially , the operation for the no - fly zone was called Operation Odyssey Dawn . As it transitioned to a full - fledged , NATO - led effort , it became Operation Unified Protector . OUP officially ended Oct . 31 , 2011 .
