9th Bomb Squadron The 9th Bomb Squadron ( 9 BS ) is a squadron of the United States Air Force . It is assigned to the 7th Operations Group , Air Combat Command , stationed at Dyess Air Force Base , Texas . The squadron is equipped with the B - 1B Lancer bomber . Formed in June 1917 , the 9 BS is the oldest bomb squadron in the Air Force . During World War I , the squadron was the first American night reconnaissance squadron to be organized . Later , it served with the Army Air Service and Army Air Corps in the Inter - War period and then served in Australia , Egypt and India during World War II . A part of Strategic Air Command during the Cold War , today the squadron is engaged as part of the Global War on Terrorism . Overview . The 9th Bomb Squadron maintains combat readiness to deliver rapid , decisive airpower on a large scale in support of conventional warfare taskings . Squadron experts provide warfighting commanders with the best in maintenance support , operational aircrews and B - 1B aircraft . The squadron repairs , services , launches , recovers and inspects 15 B - 1B Lancer aircraft capable of sustained intercontinental missions and world - wide deployment / employment from forward operating locations . Heraldry . The 9th Bomb Squadron ' s patch features 3 spotlights aiming skyward , to represent the 3 major campaigns the 9th participated in during WWI . One spotlight shines vertically , while the other two cross each other . This forms an IX , which is the Roman Numeral for 9 . History . World War I . The 9th Bombardment Squadron began as the 9th Aero Squadron at Kelly Fiele , Texas on 14 June 1917 . World War I had begun in April of that year and the unit was targeted for overseas combat duty . Their first European stop was Winchester , England in December 1917 . Following the holidays the unit moved on to RFC Grantham , England to train for combat flying the Sopwith Scout . After eight months of intensive training , the unit moved to the Western Front in August 1918 . While in Colombey - les - Belles Airdrome , France , the 9th was assigned to the First Army Observation Group . Also , after arrival in France , the unit began flying a new aircraft ; the French Breguet 14 . That aircraft would be used extensively to perform the units mission , night reconnaissance . By specializing in night reconnaissance , the 9th gained the unique distinction of being the first in the Army Air Service to do so . However , their missions were not without danger . In one case , two of the 9th aircraft were engaged by seven enemy Fokkers . The 9ths aircraft not only shot down two German aircraft , but completed their photographic mission . As the war progressed the unit participated in many night missions and battles . Most famous of those battles were the Battle of Lorraine , Battle of St Michiel , and the Meuse - Argonne Offensive . For those , the unit earned their first battle streamers . After the war had drawn to a close , the unit was moved to Trier , Germany to serve as part of the occupation force under the Third Army on 5 December 1918 . In June 1919 , the unit was ordered back to the States where they were stationed at Mitchel Field , New York ; Park Field , Tennessee ; and at March Field , California . Inter - War period . While at March , the 9th was equipped with some surplus DeHavilland DH . 4 s and assigned to the Western Department in July 1919 flying border and fire patrols . With the establishment of a permanent Army Air Service , on 14 March 1921 , the 9th Aero Squadron was re - designated as the 9th Squadron ( Observation ) . Funding shortages , however led to the squadron ' s inactivation on 29 June 1922 . While inactivated , the 9th was re - designated twice . First , as the 9th Observation Squadron on 25 January 1923 and secondly as the 9th Bombardment Squadron on 24 March 1923 . On 1 April 1931 , the 9th was activated and assigned to the 7tb Bombardment Group at Hamilton Field , California , and equipped with Keystone Light Bombers . It was in 1932 that the unit had their now familiar squadron patch approved . Designed in black and silver with three piles representing the three World War I battles the squadron took part in forming the Roman numeral IX . While with the group , the 9th flew numerous training flights in a variety of airplanes . In 1935 the unit participated in a mass bomber formation , cross - country flight from March Field , California to MacDill Field , Florida . In the summer of 1939 , the 9th received its first B - 17B Flying Fortress . However the runway at Hamilton Field was not adequate for the B - 17 , and the larger planes forced the 7th Bombardment Group to move elsewhere . In 1939 the Group was designated as a " Heavy " bomb group and was moved to Fort Douglas , Utah on September 7 , 1940 to train with B - 17s . In January 1941 , the 9th moved along with the 7th Bombardment Group to Salt Lake City Airport , Utah . In February , the squadron was upgraded to the new B - 17D Fortress , which had much improved engines and improvements in the armament . With tensions increasing in the Philippine Islands and the threat of war with the Japanese Empire growing daily , the Army wanted to send these aircraft to the Philippine Department where they would join the newly created US Army Forces in the Far East . The thinking in Washington was that if Japan attacked the Philippines , the forces there would " hold out " as long as they could on their own until they could be reinforced from the United States . In October of that year the unit prepared to take part in an exercise with the group in the Pacific area . With the ground echelon setting sail on 13 November 1941 , the 9th made ready to fly into Hickam Field , Hawaii the following month on 7 December 1941 . The B - 17s had no ammunition so more fuel could be carried on the long flight to Hawaii , and to compensate for the additional fuel stored aft of the center of gravity , the armor had been removed from the crew positions and placed , along with the machine guns , forward in the fuselage to balance the weight of the aircraft . Upon reaching Hawaii , the squadron arrived in the midst of the Japanese attack on Pearl Harbor . Unarmed and unable to fight back , the 9th lost several aircraft to enemy and friendly fire . Others scattered and landed hastily wherever they could . World War II . After the Pearl Harbor Attack in December 1941 , the squadron aircraft that had not yet been deployed to Hawaii were sent to Muroc Army Air Field to help defend Southern California from a possible Japanese attack since in the hysteria of the moment the Japanese fleet was expected to show up off Santa Barbara at any time . From Muroc , the planes flew on Antisubmarine patrols off the California coast , 8 December - c . 12 December 1941 . Battle of Java . In early January the squadron moved out , first to Hickam Field , then along a long route to the Southwest Pacific via Christmas Island Airfield , Canton Island Airfield , Tontouta Airfield on Fiji , Plaine Des Gaiacs Airfield on New Caledonia then to RAAF Base Townsville in Queensland , Australia . Upon arrival in Australia , the B - 17Ds that they had ferried to Townsville were sent to other units in Australia . Instead , the 7th Bomb Group would receive new equipment and LB - 30 Liberator s were supplied to the Group . From Australia , it was decided to send the 7th Bomb Group to airfields on Java in the Netherlands East Indies to conduct raids on advancing Japanese ground forces and naval targets . The first of the personnel of the 9th Bomb Squadron reached Java on 10 January when 3 LB - 30 Liberators landed at Bandoeng Airport , then moved on the next day to Malang , where Fifth Bomber Command had established a headquarters . Newer B - 17E Flying Fortresses , equipped with a tail gunner were sent to the area from the United States . This involved the group performing a cross - country trip from Hamilton Field to MacDill Field in Tampa , Florida . From Florida , aircraft were flown south to Trinidad , then Belém , then to Natal on the easternmost tip of Brazil . Then a flight across the South Atlantic from the tip of Brazil across to Africa and landing at the British airdrome at Freetown , Sierra Leone . Then they headed inland and north to Kano , Nigeria , and across Africa to Khartoum , Sudan . At Khartoum all the crews were automatically given cholera inoculations , then the planes flew either up to Cairo before turning eastward , or else they were sent straight east across Arabia to Aden and then northeast to Karachi . Either at Cairo or Karachi the crews first learned that Java was their destination . It was the first indication they had had that the United States had been driven out of the Philippines . The last stop was at Colombo , on Ceylon . From there the B - 17 Fortresses went straight through to Java and landed at Bandoeng Airport , where they received orders to go on to Malang Airport . On Java , the planes arrived in flights of one , two or occasionally three planes . From Malang , the planes moved to Singosari Airfield near Surabaya , in northeast Java where the 9th operated from with the 22d Bombardment Squadron . Their very first mission had given them a violent introduction to the kind of fighting they might expect from the Japanese . On 16 January two B - 17Es and three LB - 30S took off together from Singosari to attack Japanese air and naval concentrations in the Bay of Manado located at Menado in the Northern Celebes Islands , about 1 , 000 miles to the northeast . The attack force staged through an airfield on Kendari , spending the night of 16 January there , refueling and taking off in the early hours next morning . Two targets had been assigned : the B - 17s were to attack shipping in Menado Bay , while the LB - 30S bombed an airport in the vicinity . However , their orders were so unclear that the LB - 30 crews could not be sure where the airport was and they had to spend fifteen or twenty minutes searching before they finally found the field at Langoan , beside a lake , about 20 miles south of Menado . Almost in the instant that the last plane reported its bombs away , they were hit by five Zeros , and for six minutes the three LB - 30s were under fire . They managed to shoot down one of the Zeros before themselves escaping into the weather ; but two of the aircraft had been fatally hurt . In the meantime the two B - 17Es had arrived over Menado to find four transports out in the bay and two more at the docks . On their first run , because of inexperience , they got themselves so blinded by the sun that they could drop no bombs , and on the second one plane had six bombs hang in the racks ; yet as they withdrew the crews saw one of the transports capsize in the bay . Their returning course took them over the airport where the plane with the hung bombs managed to kick out two more on the runways , but the last four remained in the racks . Five minutes after this they were attacked by 15 enemy fighters . Two Messerschmitts , the rest Zeros made their passes from the rear or by diving under the bombers and pulling up behind to deliver their fire . The B - 17E Fortress tail gunners , not seen before by the enemy let them come up close . Then , for some minutes before the Japanese discovered what had been added , it beat any skeet shoot ever seen . Five Zeros and one Messerschmidt went down . There were wounded in both Fortresses , and they were forced to land at Kendari for medical aid , gas , and repairs . An hour later , while they were still at work on one of the B - 17 ' s engines , five Zeros swept in to strafe the field . One of the B - 17 ' s took off in the face of the attacking planes and successfully fought off the three that went after it . The other two Zeros shot up the airport and further damaged the B - 17 on the ground . The crew spent two more days endeavoring to repair his engines . Then , with Japanese ground troops approaching the field , they blew up the B - 17 and the crew was taken back to Malang by one of the 11th Squadron ' s LB - 30s While the B - 17s were being attacked at Kendari , the flight of three LB - 30S continued on course towards Malang . Two of the LB - 30s had to drop out , one landing at Makassar , where it had to be burned when it could not be repaired . The other LB - 30 was forced to crash - land on a streak of sandy beach on Greater Mesalembo Island . For nine days the crew waited there , with little but coconuts to live on and no proper shelter or medical care for their wounded , hoping that the wrecked plane would be spotted by a friendly aircraft . On the tenth day , they were picked up by a Navy PBY Catalina . Additional attacks against the Japanese were made but such attacks were on too small a scale to do more than delay the Japanese , to whom one or two transports were but minor losses . The effort to fulfill this program was out of all proportion to the final result ; and , as the Japanese continued their moves south though the Dutch East Indies towards Java . On 3 February , the Japanese counter - attacked by attacking Singosari Airfield where a dive - bombing and strafing attack caught the Fortresses on the field . There had been no warning and there was no defense except for that provided by some old World War I French 75S of the 131st Field Artillery . Five planes were destroyed on the ground . That was not yet the end of the day ' s black news . The 7th Group , running its first mission out of Jogjakarta Airfield that morning , had sent nine B - 17s up to Balikpapan . Eight came back . That made a total of six B - 17s lost for the day . From then on new replacement B - 17s coming in from the States via India and Africa were barely able to keep pace with the losses . The airdromes were never safe from enemy attack and being without adequate antiaircraft defenses , planes that could not get off on a combat mission early enough to evade the expected raids were sent away from the airfields at the first alarm to spend the day cruising aimlessly up and down off the south coast of Java 100 miles west of Malang , putting hour after hour on the engines and increasing the frustration of the crews . On the morning of February 8 nine B - 17s of the 7th Group took off on a mission against the airdrome at Kendari from which the Japanese were now launching most of their raids on Java . Almost immediately after taking off the formation was attacked by the Japanese . Three were shot down and the other six jettisoned their bombs and attempted to hide in the clouds . Only one of the nine planes dispatched that morning from Malang one that had returned early with engine trouble , came back undamaged . Nineteen men had been killed . On 15 February when the British surrendered at Singapore , the Japanese pincers closed on Java . A fleet of 41 transports originating at Jolo in the Philippines were heading straight down the Makassar Strait and , after a single stop at Balikpapan , moved out across the Java Sea . A second fleet , even larger , was coming down out of the China Sea around the western curve of Borneo against Batavia and Western Java . The men on the bomber fields in Java received the news of Singapore ' s surrender as forewarning of their own defeat . Attacks were flown against the fleets heading towards Java , but the Joint Army - Navy Assessment Commission credited the Army airplanes of all Allied Air forces in the theater with no more than three minesweepers , four passenger or cargo vessels , and one converted salvage vessel sunk , and a part in the sinking of two other cargo vessels . With the Japanese ground forces heading south , plans were made to evacuate the bombers back to Australia . Between the 20th and 23d Malang alone suffered twelve separate attacks , and in the four days following the disastrous 20th eight more planes were lost on the ground . On 24 February 24 six B - 17s attacked a Japanese convoy forming in the Makassar Strait for the final thrust across the Java Sea and again in the closing hours during the night of February 28 - March 1 , when six B - 17s and one LB - 30 bombed the same convoy as it moved towards the Java beaches . Their work was notable more as a gesture than for any worthwhile results and did nothing to halt or even delay the Japanese . To Fifth Bomber Command it became obvious that to continue operations on the present basis , without fighter protection and with their only three practicable airdromes under constant enemy observation , would mean the certain loss of all their planes . It was time to pull out and the remaining forces were withdrawn to Darwin , in the Northern Territory of Australia . India B - 17 operations . Re - equipped in Australia during February the unit prepared to move to a new secret station . Arriving in Karachi , India , on 12 March 1942 , they established headquarters at the Dirigible hangar seven miles east of Karachi and became one of the initial units of what became Tenth Air Force . Almost at once the 7th Bomb Group , already veterans of battle with the Japanese in Java , proceeded to hit the enemy which was at that time attempting to move into Burma . They also aided greatly in the delivery of troops to Burma and on their return trip bringing out evacuees . While this was being carried out , other members of the command were hastily constructing a permanent air base for the Group . Many of the buildings were constructed out of packing crates and other various discarded materials . The men at that time were stationed in tents located near the newly constructed headquarters . Major Cecil E . Combs , originally with the famed 19th Bomb Group , was assigned to the Group at this time and assumed command . During the latter part of March and early April , new crews with the B - 17 type airplanes arrived from the U . S . and although forward units of the Group stationed at Agra and Calcutta were already hitting the enemy , the training of these crews was undertaken to prepare them for the future air war against the Japanese in the China - Burma - India theater . Outstanding missions during this time consisted of bomber raids on Akyab , Rangoon and various other points in Burma . Losses were slight , though a number of crews failed to return , being destroyed in the air by Japanese Zeros . Middle East operations . On June 1942 , the German Afrika Korps advance in North Africa forced the British Eighth Army to retreat towards Egypt putting British Middle East Command at risk . The United States Army Air Forces ( USAAF ) had already planned for a buildup of American air power in the Middle East in January 1942 in response to a request from the British Chief of the Air Staff . In anticipation of the arrival of the American air groups , the War Department sent Maj . Gen . Lewis H . Brereton , commander of Tenth Air Force in India , to Cairo for temporary duty to assist the British . His orders instructed him to take as many planes as he could from India to Egypt . On 29 June 1942 , combat crews and ground men from the 9th Bomb Squadron departed from India for the Middle East for duty in that theater , to repulse the Nazis then attempting an offensive against the new invasion forces of the U . S . When these forces arrived from India , the U . S . Army Middle East Air Force ( USAMEAF ) was established and Brereton was named its commander . USAMEAF bomber forces consisted of nine B - 17Es and nineteen B - 24 Liberators formerly of the 9th Bombardment and 88th Reconnaissance Squadrons , 7th Bombardment Group . They would be organized into the 1st Provisional Bombardment Group on 20 July . It was the core of what would eventually become the 376th Bombardment Group , Ninth Air Force , which was transferred to RAF Abu Sueir , Egypt on 12 November . B - 17s would be flown on combat missions from RAF Lyddia and RAF El Fayid , Egypt , attacking the harbor at Tobruk , Libya seven times with day and night raids throughout July , continually raiding the harbor shipping and disrupting Axis storage areas . It is believed that the Fortresses were sent to the secret Gura Army Air Base , Eritrea ( Project 19 ) in August for depot - level maintenance , which was not possible at the British bases and had which been deferred since the beginning of the war in December . The B - 17Es would not engaged in combat again until mid - October , when raids on Tobruk began again on 12 October , and attacking a coastal road near Bardia , Libya on 20 October after a mission against Tobruk was cancelled due to cloud cover . They were also engaged in attacking harbor facilities and Axis naval targets on Crete and Benghazi , Libya through which Afrika Korps supplies were landed . The B - 17s made a final raid against installations at Sousse , Tunisia before being taken out of front - line service with the arrival of newer B - 24 and B - 25 units from the United States . Tenth Air Force operations . Re - equipped with B - 24D Liberator s the 9th was reassigned back to Tenth Air Force in India , where for the balance of the war , carried out long distance heavy bomb raids over Japanese targets primarily in Burma , Thailand and Indochina ; although also attacked Japanese targets in Southeastern China attacking airfields , fuel and supply dumps , locomotive works , railways , bridges , docks , warehouses , shipping , and troop concentrations in Burma and struck oil refineries in Thailand , power plants in China and enemy shipping in the Andaman Sea . Ceased bombing operations in late May 1945 and was attached to the Air Transport Command to haul gasoline from India over the Himalayas to China . Squadron demobilized in India , leaving B - 24s to Indian Colonial forces , inactivated as an administrative unit in the United States in early 1946 . Strategic Air Command . B - 29 Superfortress era . Nine months after the 9th was inactivated following World War II , it was re - activated and assigned to the 7th Bombardment Group at Fort Worth Army Airfield , Texas on 1 October 1946 . Training began in the B - 29 Superfortress in November 1946 under the standards established by Strategic Air Command . Throughout 1947 , the unit prepared its people for any combat eventuality that might arise training with assigned B - 29s in global bombardment operations . Within the United States SAC units flew many simulated attacks on major metropolitan areas . On 12 September 1947 , the 9th along with the group deployed to Giebelstadt AB , Germany . This flight was the largest bomber formation flown from Fort Worth AAF overseas to date . En - route the aircraft flew to Maine over Greenland , Iceland , Great Britain and landing in Germany on 13 September . During the unit ' s ten - day deployment , they participated in training operations over Europe and redeployed to Fort Worth Army Air Field on 23 September 1947 . On 2 November 1947 , the 9th participated in a 30 - day Far East Deployment and training exercise . However , the exercise was pushed back to 6 November and on that date the 9th deployed four B - 29s to NAS Barbers Point , Hawaii en route to Yokota AB , Japan . At Hawaii it was discovered that the fuel used in the Pacific was not compatible for the B - 29s . Based on that , the aircraft returned to Fort Worth Army Airfield on 8 November 1947 . In February 1948 , the 9th deployed to Germany for temporary duty in three flights , flying three different routes to Europe . The first flight of three B - 29s departed Carswell on 25 February by way of Westover AFB , Massachusetts ; Keflavik AB , Iceland ; and finally landing at Fürstenfeldbruck Air Base , Germany . The next flight departed on 26 February with four B - 29 aircraft by way of MacDill AFB , Florida ; Lajes Field , Azores to Fürstenfeldbruck AB . The last flight , consisting of the remaining three aircraft in the squadron left Carswell on 27 February and flew to Lajes Field then on to Fürstenfeldbruck . By 27 February , all 9th Bomb Squadron aircraft were in place for the 90 - day deployment . On 25 April the unit returned to Fort Worth Army Airfield after a very successful deployment in which the unit gained valuable training experience in Europe . B - 36 Peacekeeper era . On 1 July 1948 , the 9th received its first Convair B - 36A Peacemaker , the initial production version of the bomber , followed by a second B - 36 on 12 July . Flying the massive new bomber , the squadron prepared for a maximum effort flight in July over New York City to celebrate the opening of the New York City International Airport . The 7th Bombardment Wing was designated as the lead unit in the formation led by Major General Roger M . Ramey , Eighth Air Force commander . The 9th flew three B - 29s in that formation . During August 1948 , the 9th received two more B - 36As for a total of nine wing assigned B - 36s . On 17 December , four B - 36s from the 9th took part in a SAC maximum effort mission . A total of ten wing bombers flew missions to key cities in the United States . Those flights gave the American public their first look at the worlds largest bomber . By October 1948 , the wing possessed a total of 18 of the B - - 36A aircraft . Of those , the 9th Bombardment Squadron had five . On 19 November , the 9th transferred their final B - 29 to the 97th Bombardment Group at Biggs AFB , Texas . That transfer left the 9th an all B - 36 squadron . In January 1949 , the United States had a new President , Harry S . Truman , and the 9th participated in the B - 36 formation to commemorate the inauguration at Washington D . C . On 15 February the 9th , along with the wing , flew a sixteen ship formation commemorating air ' progress in an aerial review over Andrews Air Force Base , Maryland . That formation was the largest B - 36 formation to date of the worlds largest bomber . In August 1950 , the unit began participating in simulated bombing missions to Limestone AFB , Maine at the rate of one per day . Maximum training requirements would be met on the missions along with fighter exercises . The missions would consist of simulated radar bombing of St Louis , Missouri . The exercise was very successful and the aircraft recovered at Carswell on 24 August 1950 . In early 1950 , Convair began conversion of the B - 36As to the RB - 36A reconnaissance configuration , and in August , the squadron began receiving the twin - turbojet fitted B - 36D . In December 1950 the unit took part in flight to Ramey AFB , Puerto Rico . This was the first time wing B - 36s had landed in Puerto Rico . Next , the 9th along with the wing participated in a special training mission to the United Kingdom , landing at RAF Lakenheath . The purpose of the mission was to evaluate the B - 36D under simulated war plan conditions . This marked the first time that B - 36s had flown outside US territory . The flight carried out a simulated night radar bombing attack on Helgoland , on the West German coast . The aircraft returned to Carswell on 20 January In June 1951 three bomber crews were assigned to the Convair - operated Air Force Plant 4 at Fort Worth temporarily to participate in the B - 36F operational training program . As 1952 closed the 9th was transitioning into the B - 36F model . The 9th opened 1953 by deploying to RAF Fairford , United Kingdom as part of a unit simulated combat mission . Six B - 36F aircraft took part . All year the squadron was involved in stepped - up training missions throughout the world , when the squadron was deployed on a simulated combat mission to Nouasseur AB , French Morocco , North Africa , 7 – 14 October . This was the first time the wing and 9th deployed to North Africa . At the end of 1953 , the squadron began receiving upgraded B - 36H aircraft Throughout the early part of 1958 squadron B - 36 crews rotated to Castle AFB , California for B - 52 Stratofortress training . Also , the first B - 36s were retired to storage at Davis - Monthan AFB , Arizona starting in January . On 30 May the last wing B - 36 was retired . B - 52 Stratofortress era . Special research missions were flown by the 9th in the B - 52F from October 1959 to June 1960 with the AGM - 28 Hound Dog air - launched cruise missile , although the squadron never employed them on nuclear alert duty . Afterwards , the squadron supported SAC ' s Worldwide Airborne Alert Force from 1960 to 1965 . In June 1964 , the Air Staff approved the modification of 28 B - 52Fs under a project known as South Bay . They could carry 24 750 - pound bombs externally . The bombs were carried on external pylons installed underneath each wing inboard of the inner engine pods . These pylons had originally been designed to carry the Hound Dog cruise missile . From May to November 1965 , the unit deployed to Andersen AFB , Guam in support of Operation Arc Light missions . The squadron first attacked suspected Viet Cong enclaves at Ben Cat , 40 miles north of Saigon , South Vietnam , on 18 June , the operation being supported by KC - 135A Stratotankers stationed at Kadena AB , Okinawa . Prior to the mission , the crews were briefed that a minimum of 2000 - 3000 ( possibly as high as 6000 or more ) North Vietnamese regular army troops were encamped in the target area . To ensure security , it was planned that the raid would be carried out in complete radio silence from beginning to end . The raid did not start off well , as on the way to the target , two B - 52Fs collided in midair during a refueling operation and 8 crew members were killed . An investigation later blamed the cause for the mid - air collision on a combination of poor staff planning , extremely unusual and unique weather conditions , forbidden radio communications and an untested air refueling operation . The next day , the press back in the United States generally derided the raid as being an expensive and costly failure , and it was claimed that only one water buffalo was killed and only 100 pounds of rice were destroyed . However , it seems that the results of the raid were a lot more effective than the press had led people to believe . All of the bombs were dropped into the correct target box , except for one string of bombs which had missed the area completely because of a radar failure . After about a week , US Army teams began to enter the area and reported almost total destruction of all life in the area . Additional missions were cancelled and did not resume until July . There was initially some skepticism about the usefulness of a high - altitude radar bomb drop against guerrilla forces . Nevertheless , within a few months there was universal acceptance of the power of the B - 52 raids as a new type of artillery . By November 1965 , the B - 52s were able to support the 1st Air Cavalry Division in mopping up operations near Pleiku . The unit returned to Carswell in December 1965 to joyful families in time for the holidays . In a reduction of B - 52 units for budgetary reasons , the 9th was inactivated on 25 June 1968 . Several of the B - 52s were retired , others were sent to the 93d Bombardment Wing , Castle AFB , California . FB - 111 era . On 2 July 1968 , the 340th Bombardment Group ( Medium ) was activated at Carswell AFB , Texas . Although it was given the designation of a bomb group , the 340th was organized and functioned as a SAC Wing . Its operational squadron was the 4007th Combat Crew Training Squadron ( CCTS ) . The 340th BMG was given the primary mission of conducting initial qualification training for General Dynamics FB - 111A aircrew members . The FB - 111A was the all - weather strategic bombing version of the F - 111 strike aircraft , intended as an interim successor to the B - 52 Stratofortress and B - 58 Hustler of the Strategic Air Command . Due to the delayed delivery of FB - 111A from General Dynamics , the Group ' s training mission suffered . Delivery of the first a / c , 67 - 7193 , took place in late September 1969 , followed by the second FB - 111A on October 25 . These two planes were powered by TF30 - P - 12A engines . Problems with the Mark IIB avionics slowed further deliveries , with the Air Force not accepting its next FB - 111A until 23 June 1969 . On 8 October 1969 , the 7th FB - 111A entered service with the 4007th Combat Crew Training Squadron . Even though the FB - 111A was officially declared operational , it had yet to reach the combat forces . After reaching operational capability , the 4007th CCTS relocated to Plattsburgh AFB , New York and became part of the 380th Strategic Aerospace Wing in an administrative re - assignment , with its personnel and equipment reassigned to the re - activated 9th Bombardment Squadron ( Medium ) , becoming the first SAC operational bomb squadron to fly the FB - 111A . The crash of a F - 111 at Nellis AFB in December 1969 caused the grounding of all F and FB - 111A a / c . The Group flew T - 33 Shooting Star trainers until flying activities with the FB resumed in June 1970 and delivery of " FB " resumed on 25 July 1970 . By the end of September , the unit possessed 20 FB - 111A assigned aircraft . In January 1971 , the FB - 111A achieved initial operational capability with the 509th Bomb Wing ( 393d and 715th Squadrons ) based at Pease AFB , New Hampshire .
