Davis – Monthan Air Force Base Davis – Monthan Air Force Base ( DM AFB ) is a United States Air Force base located within the city limits , and approximately south - southeast of downtown , Tucson , Arizona . The host unit at Davis – Monthan is the 355th Fighter Wing ( 355 FW ) assigned to Twelfth Air Force , which is headquartered at DM and is part of Air Combat Command ( ACC ) . The 355 FW and various tenant units located on base provide A - 10 Thunderbolt II close air support ; OA - 10 forward air controllers ; air liaison officers ; EC - 130 command , control and communications warfare ; air control radar ; combat search and rescue ; and combat support forces to unified commanders . The 355 FW also provides initial and recurrency flying training to all U . S . Air Force A / OA - 10 and EC - 130 pilots and crews ; and is the ACC ' s executive agent for INF and START treaty compliance . Although under ACC , it is best known for its role as the location of the Air Force Materiel Command ' s 309th Aerospace Maintenance and Regeneration Group ( AMARG ) , better known as the sole aircraft boneyard for all excess military and government aircraft , as its location allows for preservation of the aircraft . Davis – Monthan AFB was established in 1925 as Davis - Monthan Landing Field , and is named in honor of World War I pilots Lieutenants Samuel H . Davis ( 1896 – 1921 ) and Oscar Monthan ( 1885 – 1924 ) , both Tucson natives . Overview . Davis – Monthan Air Force Base is a key ACC installation . The 355 FW is the host unit providing medical , logistical , mission support , and operational support to all assigned units . The wing ' s missions are to train A - 10 and OA - 10 pilots and to provide A - 10 and OA - 10 close support and forward air control to ground forces worldwide . One of the wing ' s tenant units , the 55th Electronic Combat Group , is tasked to provide command , control , and communications countermeasures in support of tactical forces with its EC - 130H aircraft and , employing the EC - 130E aircraft , provide airborne command , control , and communications capabilities for managing tactical air operations in war and other contingencies worldwide . Two other major tenants , the 563rd Rescue Group ( structured under the 23d Wing , Moody Air Force Base ) and 943rd Rescue Group , ( structured under the 920th Rescue Wing , Patrick Air Force Base ) , are tasked to provide combat search and rescue support worldwide . Although under ACC , it is best known for its role as the location of the Air Force Materiel Command ' s 309th Aerospace Maintenance and Regeneration Group ( AMARG ) , better known as the sole aircraft boneyard for all excess military and government aircraft . Davis - Monthan was selected due to its low humidity and hard , alkaline soil , which allows the aircraft to be naturally preserved for cannibalization or possible reuse . Wing units . The host wing at Davis - Monthan is the 355th Fighter Wing , which includes : Tenant units . The base provides additional active duty support to the 162d Fighter Wing ( 162 FW ) of the Arizona Air National Guard , located at nearby Tucson International Airport , which flies the F - 16C and F - 16D Fighting Falcon . Other military activities and federal agencies using the base include Navy Operational Support Center Tucson , a detachment of the Naval Air Systems Command , the Federal Aviation Administration , the U . S . Customs Service Air Service Branch , the U . S . Army Corps of Engineers , and the Federal Law Enforcement Training Center . Also located on base is the 25th Operational Weather Squadron 25 OWS . The squadron produces forecasts for the Western United States and is part of the 1st Weather Group ( 1 WXG ) headquartered at Offutt Air Force Base , Neb . The squadron also serves as a training hub for new weather professionals - both enlisted and officers . History . The base was named in honor of Lieutenants Samuel H . Davis and Oscar Monthan , two Tucsonans and World War I – era pilots who died in separate military aircraft accidents . Davis , who died in a Florida aircraft accident in 1921 , attended the University of Arizona prior to enlisting in the Army in 1917 . Monthan enlisted in the Army as a private in 1917 , was commissioned as a ground officer in 1918 , and later became a pilot . He was killed in a crash of a Martin bomber in Hawaii in 1924 . Origins . In 1919 , the Tucson Chamber of Commerce aviation committee established the nation ' s first municipally owned airfield at the current site of the Tucson Rodeo Grounds . The rapid increase in aviation activities meant a move in 1927 to the site which is now Davis – Monthan Air Force Base . After the City of Tucson acquired land southeast of town for a runway in 1925 , Charles Lindbergh , fresh from his nonstop crossing of the Atlantic Ocean , flew his " Spirit of St . Louis " to Tucson in 1927 to dedicate Davis - Monthan Field , then the largest municipal airport in the United States . Military presence at the field began when Sergeant Simpson relocated his fuel and service operation to the site on 6 October 1927 . He kept a log containing names of the field ' s customers , including Lindbergh , Amelia Earhart , Benjamin Foulois , and Jimmy Doolittle . Doolittle , awarded the Medal of Honor for his 1942 Tokyo raid , was the first military customer at the field on 9 October 1927 . The combination of civil and military operations worked well until the early 1940s , when military requirements began to require the relocation of civil aviation activities . World War II . Davis - Monthan Airport became Tucson Army Air Field in 1940 as the United States prepared for World War II . The first assigned U . S . Army Air Corps units were the 1st Bomb Wing , 41st Bomb Group , and 31st Air Base Group , activating on 30 April 1941 . In its military role , the base became known as Davis - Monthan Army Air Field on 3 December 1941 . Even before Pearl Harbor on 7 December 1941 , Air Corps leaders started to increasingly utilize the airfield , sending Boeing B - 29 Superfortress es and Consolidated B - 24 Liberator heavy bombers and Douglas B - 18 Bolo which were used both for training and observation missions . Several known bombardment groups trained at the base during the war : Training at the airfield came to a halt on 14 August 1945 , when the Japanese unconditionally surrendered . Davis - Monthan played a post - war role by housing German POW ' s from June 1945 to March 1946 . Postwar years . With the end of the war , operations at the base came to a virtual standstill . It was then the base was selected as a storage site for hundreds of decommissioned aircraft with the activation of the 4105th Army Air Force Unit . The 4105th oversaw the storage of excess B - 29s and C - 47 " Gooney Birds . " Tucson ' s dry climate and alkali soil made it an ideal location for aircraft storage and preservation , a mission that has continued to this day . The airfield also acted as a separation center , which brought the base populace to a high of 11 , 614 people in September 1945 . Cold War . The Cold War era was ushered in at Davis - Monthan in March 1946 , in the form of the 40th and 444th Bombardment Groups , both equipped with B - 29s . As part of the postwar austerity , these groups were inactivated , with the personnel and equipment being consolidated into the 43d Bombardment Group in October . On 11 January 1948 , with the establishment of the United States Air Force , the facility was renamed Davis – Monthan Air Force Base . On 30 June 1948 , the Air Force activated the 43rd Air Refueling Squadron , whose KB - 29Ms were newly equipped with aerial refueling equipment purchased from the British firm FRL . The 43rd ARS , along with the 509th ARS at Walker AFB , New Mexico , was the first dedicated air refueling unit in history . On 2 March 1949 , the " Lucky Lady II " , a B - 50A of the 43d Bombardment Wing , completed the first nonstop round - the - world flight , having covered in 94 hours and 1 minute ( 249 . 45 mph ) . " Lucky Lady II " was refueled four times in the air by KB - 29 tankers of the 43d Air Refueling Squadron , which had made only one operational air refueling contact before the mission . For this outstanding flight , the " Lucky Lady II " ' s crew received the Mackay Trophy , given annually by the National Aeronautic Association for the outstanding flight of the year , and the Air Age Trophy , an Air Force Association award , given each year in recognition of significant contributions to the public understanding of the air age . In 1953 , the jet age came to Davis - Monthan when SAC units on the base converted to the new Boeing B - 47 Stratojet . The 303d Bombardment Wing , Medium , was initially established on 27 August 1951 , and activated at Davis - Monthan AFB on 4 September 1951 . The wing operated B - 29s until January 1952 , when it was equipped with KB - 29s . On 20 January 1953 , the 303d transitioned to the Boeing B - 47 Stratojet for its three bomb squadrons , while an additional air refueling squadron equipped with KC - 97s was assigned to the wing between 18 February 1953 , and 1 February 1956 . A standard SAC Alert Area ramp was constructed in the southeast corner of the base adjacent to the runway and the 303d assumed nuclear alert responsibilities was final conversion and checkout in the B - 47 was complete . In April 1953 the Air Defense Command ' s ( ADC ) 15th Fighter - Interceptor Squadron was activated with F - 86A Sabre s . A year later , the unit transitioned into F - 86Ds followed by a transition to F - 86Ls in the fall of 1957 . In the spring of 1959 the unit received Northrop F - 89J interceptors which it flew for only a year when it transitioned into McDonnell F - 101Bs . On 24 December 1964 , the 15th FIS was inactivated . In 1962 , the Strategic Air Command ' s 390th Strategic Missile Wing ( 390 SMW ) and its 18 Titan II ICBM sites around Tucson were activated . The 390 SMW was one of only three Titan II missile wings in SAC and represented the heaviest land - based missile and the largest single warhead ever fielded by U . S . strategic deterrent forces . In July 1963 , the 4028th Strategic Reconnaissance Weather Wing , equipped with U - 2 strategic reconnaissance aircraft , began flying global missions from Davis - Monthan . Following the Cuban Missile Crisis in 1963 , the 4080th Strategic Reconnaissance Wing at Laughlin AFB , Texas , relocated to the base and assumed responsibility for all U - 2 operations , emphasizing long - range strategic reconnaissance and intelligence collection . As a Strategic Air Command ( SAC ) unit , the 4080th was later redesignated the 100th Strategic Reconnaissance Wing and also acquired Lockheed DC - 130 Hercules aircraft for launch and control of Firebee reconnaissance drones that were the precursors of contemporary unmanned aerial systems . The DC - 130s and U - 2s remained at the Davis - Monthan until 1976 , when the 100 SRW was inactivated , its DC - 130s transferred to Tactical Air Command ' s 432d Tactical Drone Group , and its U - 2s transferred to SAC ' s 9th Strategic Reconnaissance Wing ( 9 SRW ) at Beale Air Force Base , California , where U - 2 Dragon Lady operations were consolidated with SR - 71 Blackbird operations . On 15 June 1964 , Davis - Monthan ' s 303d Bombardment Wing was inactivated as part of the retirement of the B - 47 Stratojet from active service . The year 1964 brought back the combat crew training mission of the World War II years with the 4453d Combat Crew Training Wing equipped with the Air Force ' s newest and most sophisticated fighter , the McDonnell Douglas F - 4 Phantom II . In July 1971 , the 355th Tactical Fighter Wing , flying the A - 7 Corsair II aircraft , was activated at the base and the previously assigned F - 4s were moved to Luke AFB , near Phoenix , Arizona . On 1 October 1976 , the base was transferred to Tactical Air Command ( TAC ) after 30 years under SAC . It was also that year the 355th Tactical Fighter Wing accepted the first A - 10 Thunderbolt II . Since 1979 , D - M has been the training location for pilots in the A - 10 ; the base was redesignated the 355th Tactical Training Wing on 1 September 1979 . The organization was later redesignated the 355th Fighter Wing since it includes operational , deployable A - 10 squadrons in addition to its CONUS training mission The 1980s brought several diverse missions to D - M . The headquarters charged with overseeing them was now the 836th Air Division , which was activated 1 January 1981 . The AD advised Air Force component commanders and land forces on A - 10 aircraft tactics , training , employment and readiness , and subordinate units participated in exercises such as Red Flag and Celtic Echo . The 41st Electronic Combat Squadron , equipped with the EC - 130H Compass Call aircraft , arrived on 1 July 1980 , and reported to the 552d Airborne Warning and Control Wing . In 1981 D - M welcomed the 868th Tactical Missile Training Group . The 868th was the only U . S . - based Ground Launched Cruise Missile ( GLCM ) unit and the source of the crews that staffed the forward deployed GLCM wings in NATO in 1982 . On 1 September 1982 , the headquarters of the 602nd Tactical Air Control Wing ( TAIRCW ) and its subordinate 23rd Tactical Air Support Squadron ( TASS ) , a unit responsible for the Air Force ' s tactical air control system west of the Mississippi River transferred from Bergstrom Air Force Base , Texas , and stood up at D - M , bringing 16 OA - 37B aircraft and numerous new personnel to the base . The 23rd TASS became the Air Force ' s first O / A - 10 squadron in 1988 , providing heavily armed airborne forward air control ( FAC ) capability for the first time . Unlike all other D - M aircraft at the time , the 23rd TASS fleet ' s tail flash read " NF " , for " Nail FAC " ; the squadron ' s radio call sign was " Nail . " In 1984 , as a result of the first series of Strategic Arms Reduction Treaties START I between the United States and the Soviet Union , SAC began to decommission its Titan II missile system . In 1982 , the 390 SMW began removing its 18 missiles and inactivating the associated sites in preparation for eventual demolition . In October 1981 , President Ronald Reagan announced that , as part of the strategic modernization program , Titan II systems were to be retired by 1 October 1987 . Deactivation began at Davis - Monthan on 1 October 1982 . During the operation , titled " Rivet Cap " , the missiles were removed and shipped to Norton AFB , California for refurbishment and storage . Explosive demolition began at the headworks of missile complex 570 - 7 on 30 November 1983 . In May 1984 , the 390 SMW ' s last Titan II at Davis - Monthan came off alert status . SAC subsequently inactivated the 390th Strategic Missile Wing on 30 June 1984 . One site under the 390 SMW , known both as Titan II Site 571 - 7 and as Air Force Facility Missile Site 8 , was initially decommissioned in 1982 . Located approximately south of Tucson in Sahuarita , Arizona , it was saved from demolition and turned over to the Arizona Aerospace Foundation , a nonprofit organization which also administers the Pima Air and Space Museum immediately south of Davis - Monthan . With a variety of items on loan from the National Museum of the United States Air Force , including an inert Titan II missile , Site 571 - 7 is now known as the Titan Missile Museum and is the sole remaining example of a Titan II missile site in existence . In 1994 , the site was declared a National Historic Landmark . Modern era . In the 1990s , the 355 TTW continued to train A - 10 crews for assignments to units in the United States , England , and Korea . During this period , the 602nd Tactical Air Control Wing deployed Airborne Forward Air Controllers in their OA - 10 aircraft to Operation Desert Storm , providing nearly 100 percent of this capability to the war . On 1 October 1991 , the 355 TTW was redesignated as the 355th Fighter Wing ( 355 FW ) in tune with the Air Force ' s Objective Wing philosophy . The 355th Fighter Wing was composed of the 355th Operations Group ( 355 OG ) , the 355th Maintenance Group ( 355 MG ) , the 355th Medical Group ( 355 MDG ) , and the 355th Mission Support Group ( 355 MSG ) . In May 1992 , the 41st and 43d Electronic Combat Squadron , flying EC - 130E Hercules Compass Call arrived . The aircraft carried an airborne battlefield command and control center capsule that provides continuous control of tactical air operations in the forward battle area and behind enemy lines . This capability added yet more strength to the wing ' s combat capability . The 43rd Electronic Combat Squadron " Bats " are part of the 55th Wing ( 55 WG ) at Offut AFB , Nebraska , but operate out of Davis - Monthan . In addition , the 42d Airborne Command and Control Squadron arrived from Keesler AFB , Mississippi on 19 July 1994 . On 1 May 1992 , senior Air Force leaders implemented the policy of one base , one wing , one boss . The 836 AD and 602 TAIRCW inactivated while the 41 ECS and 43 ECS came under control of the 355 FW . With the mission diversified , the 355th Fighter Wing was redesignated as the 355th Wing ( 355 WG ) . Following Operation Desert Storm , the 355 WG supported Operation Southern Watch during deployments to Al Jaber , Kuwait , in 1997 by deploying 24 A - 10s , in 1998 by deploying 16 A - 10s , and in 1999 by deploying 14 A - 10s — all to ensure compliance of the 33rd parallel southern no - fly zone . The flight and mysterious crash of Captain Craig D . Button took off from Davis – Monthan Air Force Base on 12 April 1997 . Global War on Terrorism . The attacks on 11 September 2001 , led to the initiation of three ongoing missions : Operation Enduring Freedom ( OEF ) , Operation Iraqi Freedom ( OIF ) , and Operation Noble Eagle ( ONE ) . After the execution of Operation Enduring Freedom , eight A - 10s from the 355 WG were called to Bagram Air Base , Afghanistan , to fly close air support missions supporting multinational ground forces . In September 2002 , the 48th , 55th , and the 79th Rescue Squadron ' s ( RQS ) transferred under control of the 355 WG , equipped with HC - 130 aircraft and HH - 60 helicopters . At the same time , the 41st and 43d Electronic Combat Squadrons were realigned under the control of the 55th Electronic Combat Group ( 55 ECG ) . While personnel and aircraft remained on Davis - Monthan AFB , operational control of the 55 ECG was assumed by the 55th Wing at Offutt AFB , Nebraska . Another major wing realignment occurred on 1 October 2003 , with the activation of the 563rd Rescue Group ( 563 RQG ) on Davis - Monthan AFB . Control of the 48th , 55th , and 79th Rescue Squadrons ( RQS ) was passed to the new group with the 23rd Wing ( 23 WG ) at Moody Air Force Base , Georgia assuming operational command of the unit . In 2003 and 2005 , the 354th Fighter Squadron ( 354 FS ) " Bulldogs " deployed on five - month deployments to Bagram Air Base in Afghanistan . During these deployments , they provided 24 - hour presence to reassure the Afghan population as it struggled with its emergent democracy , and provided key support during national elections . While the 2003 deployment saw limited action , the Bulldogs employed over 22 , 000 rounds of 30 mm during 130 troops - in - contact situations during the 2005 deployment . Returning to Afghanistan in April 2007 for another six - month deployment , the 345th again provided 24 - hour presence and Close Air Support expertise to coalition forces in support of Operation Enduring Freedom . During this period , insurgent activity level was the highest recorded to date in OEF . The Bulldogs employed an unprecedented number of munitions during this deployment — over 150 , 000 rounds of 30 mm in support of over 400 troops - in - contact situations . Another major change occurred on 26 April 2007 . With only A - 10 fighter aircraft assigned , the 355th Wing was redesignated once again as the 355th Fighter Wing ( 355 FW ) . Also in 2007 , the 214th Reconnaissance Group ( 214 RG ) , an Arizona Air National Guard unit , was activated . Today , the 355 FW is composed of four groups : the 355th Operations Group ( 355 OG ) , the 355th Maintenance Group ( 355 MG ) , the 355th Mission Support Group ( 355 MSG ) , and the 355th Medical Group ( 355 MDG ) . Together , along with their tenant organizations , they make up the 6 , 000 Airmen and 1 , 700 civilian personnel at Davis - Monthan AFB . On Friday , 16 September 2011 , the Base was placed on lockdown ; news agencies reported shots may have been fired , possibly with injuries ( the military spokesperson later said this was not the case , the base was simply on alert because an armed individual walked on to and was holed up in a building on the base ) . An ambulance had been called , but that was coincidental - a case of bad timing - as it was meant for a woman that had gone into labor . The military spokesperson , Technical Sergeant Russ Martin , stated that in fact there were no injuries or shots fired . No one is allowed on or off the Base ; all students were accounted for . Because of the lockdown , there was a single point of entry at the Base . Later , the lockdown was ended ; the situation apparently was peacefully resolved .
