Santa Ana Army Air Base (SAAAB) was an air base without planes, hangers or runways. It was a huge basic training camp where newly inducted soldiers, earmarked for the Army Air Forces, were given 9 weeks of basic training and then testing to determine if they were to be pilots, bombardiers, navigators, mechanics, etc. From SAAAB, they went on to other bases for training in their specialties. The base was dedicated in March 1942 and grew rapidly as the need for pilots and air crews sky-rocketed. Turnover was rapid so that by the end of the year 23,470 soldiers had passed through SAAAB. By the end of 1943 that number jumped to 57,895. In the Fall of 1942 SAAAB became an Overseas Replacement Depot (ORD) housing Army Air Forces personnel awaiting transportation overseas. In November of 1943 members of the Women's Air Service Pilots (WASP) began training at the base, followed shortly by members of the Women's Army Corp (WAC). In 1945 SAAAB became one of six Redistribution Centers in the country for airmen returning from overseas who were to be assigned state-side duty.
Being close to Hollywood and with such a large turnover of service personnel, the base attracted a lot of Hollywood celebrities who put on shows at the base.

In late 1945 Japanese aliens from the alien in ternment camps being returned to Japan by the Immigrations and Naturalization Service (INS) were housed here while awaiting transportation to Japan
SAAAB continued as a redistribution and separation center for a short time after the war. On March 31, 1946, the base was ofically deactivated. However, in 1956 elements of the 551st Antiaircraft Artillery Missile Battalion brought the Nike-Hercules system from Fort Bliss and temprarily installed and operated it at the old SAAAB site until their permanent installations (Site LA-88) in Chatsworth and atop Oak Mountain were completed.

In 1958 the base was declared surplus and soon afterwards the land was divided for many uses. In the postwar years private homes, apartments, two colleges, the Costa Mesa Air National Guard Station and the Orange County Fairground shared the land. Many of the base's original buildings remained in use for years by the colleges and the fair grounds.

History of Santa Ana Army Air Base (SAAAB)
By Justin M. Ruhge, Goleta Valley Historical Society
The SAAAB was one of three national training centers established on July 1940 to train pilots for the Army Air Corps. The original locations were at Maxwell Field, Montgomery, Alabama, Randolph Field, San Antonio, Texas and Moffett Field, Sunnyvale, California. These three Centers were to train a total of 7,000 pilots per year. However the national program was increased to 30,000 pilots per year in August of 1940. Many contract training schools were started to help fill this quota. In February 1941, the Army initiated three Air Corps Replacement Training Centers. These were induction centers for new recruits entering the Air Corps with no military experience. Each center was to provide for the classification and preflight instruction for pilots, navigators and bombardiers. The locations were to be at existing air corps facilities. This was the case except for the West Coast Air Corps Training Center at Moffett Field. The Navy wanted to use the field exclusively for it's lighter than air "blimp" base so the Army Air Corps had to look elsewhere for a new facility. A search of sites in southern California was conducted. The City Council of Santa Ana wanted the new center located near it so they arranged to lease a 409-acre site for $6,400 per year from M. H. Whittier Co. Ltd. with an option to buy at $500 per acre. The government could sublet from the city for $1 per year. In addition, the County agreed to lease five acres of land on the new Orange County Airport for use by Army planes for officers' commuting purposes. The Army selected the Santa Ana site on June 16, 1941. The City leased the land on August 21, 1941.

The Base, called an Air Corps Cadet Replacement Training Center, later renamed the Santa Ana Army Air Base, was planned to accommodate 2,500 to 3,000 cadets, 83 officers and 806 enlisted men, and to cost about $3,200,000 to construct.

The Base would not have a flying field as a part of its facilities. It would receive air cadets from civilian life and give them basic training prior to their advancement to one of the contract primary aviation schools for flight training. Arrangements were also made for a Special hangar at the Orange County Airport to accommodate officers' planes.

The master plan called for the construction of 145 buildings that would include: 79 barracks, 3 warehouses, quartermaster supply office, 4 school buildings, 10 administration buildings, 13 day rooms, 13 supply rooms, 4 cadet messes, 2 officers' quarters, a motor repair shop, post office, gasoline service station, utility buildings, theater, 2 recreation buildings, commissary buildings, chapels, dispatchers' office, officers' mess, fire station, guard house, two post exchanges, and a 151-bed hospital and all utilities. This would amount to a new city in the middle of bean and tomato fields.

Meanwhile in the middle of all these preparations, on June 20, 1941 Army Regulation 95-5 changed the name of the Air Corps to the Army Air Forces.

The Orange County Airport was also selected as the site for the Headquarters Squadron originally located at Moffett Field. As a result, a dozen or more aircraft were located at Orange County Airport to serve as a sort of "taxi service" for the Army Air Force officials to permit them to contact various points of flying activity along the West Coast. Plans were also made to move the entire Army Air Force administrative offices at Moffett Field to the Santa Ana area.

To provide the basic staff for the SAAAB at Santa Ana, two squadrons, the Headquarters and Headquarters Squadron (Special) and the 554th School Squadron, were activated at Moffett Field on August 1, 1941. These two squadrons became the nucleus from which the SAAAB cadre would grow.

The construction contract for the 177 buildings at SAAAB was awarded to the Griffith Company on October 24, 1941 for $2 million. The work was to be completed in 120 calendar days.

New plans required that the SAAAB accommodate the training of 10,000 cadets per year.

The SAAAB was to be the starting point of the cadet's 35-week training course. During the first five weeks spent at the SAAAB the cadet would receive his uniforms, regulations and initial instruction in drill, military courtesy and other basic training. Upon leaving the SAAAB he would be assigned to a school for ten weeks of primary flight instruction, then on to a school for ten weeks of basic flight instruction and finally to an advanced flying field for 10 weeks. At the end of his 35 weeks of training the cadet was to be commissioned a second lieutenant in the Army Air Forces.

The first Commander of the Aviation Cadet Replacement Training Center at Santa Ana or later (SAAAB) was Major William A. Robertson who arrived on October 10, 1941. He was promoted to Colonel on March 1, 1941.

As a direct result of the December 7, 1941 attack on Pearl Harbor, the number of pilots to be trained was increased three-fold to 102,000. This new number placed pressure on the SAAAB to increase its facilities and as a result 924 acres were acquired by the U.S. Government next to the present site for the addition of barracks and other buildings.
The first set of buildings was completed on May 15, 1942; however, the officers and men began to move into the base on February 16, 1942. General Orders No. 14 made it official on March 3, 1942. The first group of 50 cadets arrived on February 20, 1942. On February 25, 1942 the Headquarters and Headquarters Squadron with its enlisted men and approximately 2,000 cadets arrived to begin training. By March there were 5,000 cadets on the base. Cadets lived in tents until the new barracks could be completed. Instruction began in March for a nine-week course. In May 1942 the base was organized into Wings, Groups and Squadrons. A wing consisted of ten squadrons, divided into two Groups. A squadron usually had about 180 men. This was broken into flights and then squads.

On May 13, 1942 the Air Base officially became known as the Santa Ana Army Air Base (SAAAB) by General Order No. 19.

In March 1942 the Army established separate classification centers for aircrew candidates. These were established near the preflight schools. The West Coast center was located at the SAAAB on June 15, 1942. Separate buildings were constructed for this center. The centers function was two-fold - to serve as a processing and classifying center and to create a reserve pool of classified students. At the centers, thousands of civilians came into the Army for aviation cadet training to receive a physical examination, inoculations and be quarantined for several weeks. During this period, cadets received uniforms, equipment, and indoctrination into the ways of military life. They were also tested and classified for aircrew training either as a pilot, navigator or bombardier. The typical cadet spent his first three weeks in the classification center. These three new centers replaced some of the earlier functions of the SAAAB and thus allowed more attention for the three training schools.

On October 30, 1942 the Santa Ana Branch School of Aviation Medicine was established at the SAAAB hospital to provide practical training for officers of the Medical Corps.
On June 11, 1942 General Order No. 11 changed the old Aviation Cadet structure to three Army Air Forces units. These were an Air Force Classification Center, an Army Air Forces Preflight School for Pilots and an Army Air Forces School for Bombardiers-Navigator.

The first class of 2,601 cadets graduated on July 1, 1942. By the end of 1942 the annual rate of graduates from the Pilot School was over 45,000. To carry out this program, the Air Force had recruited a faculty of over 250 well-trained and experienced high school, college and university teachers who later became officers in the Air Corps.

The Sunday review was the only regular ceremony. The "E" flag was awarded to the squadron that excelled in marching and good conduct.

The Base Newspaper was begun July 2, 1942 and dubbed The Cadet. It was published by the Cadet Press of Anaheim, which also published the weekly Anaheim Gazette.

In March 1943 the Women's Army Corps (WAC) was established at SAAAB. Special barracks were constructed for them on the edge of the property.

The proficiency level of the cadets was improved by the introduction of the College Training Program in January 1943. By the end of 1943, some 41,216 college students had been sent to the SAAAB.

The Base reached its maximum strength by the fall of 1943, with a population of some 26,000 servicemen.

The SAAAB graduated 23,479 cadets in 1942 and 57,895 in 1943. In September 1943, the SAAAB began to train Chinese Air Force officers. In September 1943 the SAAAB hospital was authorized to serve as one of seven convalescent centers in the Army Air Forces. The mission of the convalescent center was to provide medical service and rehabilitation for all Army Air Forces personnel transferred from General Hospitals and other sources.

The hospital convalescent patients published their own newspaper called the Wardbird.

Preflight training at the SAAAB peaked in the latter part of 1943. Pilot class 44D, the largest, completed training in October 1943. By then, the Army Air Forces had enough aircrews for the foreseeable future.

On May 31, 1944 aircrew classification ceased at the SAAAB, only about two years since a began. The Pilot School closed on May 22, 1944. It had received 73,923 cadets and graduated 70,464 for flying schools. By the end of 1944 most pilot training schools were being closed by the Army Air Forces.

On November 1, 1944 the SAAAB was turned over to the Army Air Forces Personnel Distribution Command with General Arthur E. Easterbrook in command. At the time it had 800 buildings on the Base. Most of the remaining cadets were sent to San Antonio, Texas. From its inception until this transfer the SAAAB Classification Center had received 149, 425 men. Of that total, 82,252 were classified as pilots, 21, 842 as bombardiers and 14,230 as navigators. Classification eliminated 28,388 to ground crew and 188 to radio operator school. At its close 2,525 remained unclassified.

Convalescent Hospital activities were increased.

A new base newspaper published in magazine size and called the Crossroads, became a replacement for The Cadet.

In July 1945, 563 German prisoners-of-war from the Garden Grove POW Camp were assigned to the SAAAB.

May 7, 1945 V-E day was the close of the fighting in Europe. Suddenly SAAAB's role changed 180 degrees and it worked around the clock to become a separation center. By November 1945 81,000 combat veterans had been returned to private life.

Finally on March 13, 1946 the Army deactivated the SAAAB. On May 4, 1946 the title to the SAAAB passed from the Army to the War Assets Administration. In the ensuing years some of the buildings on the base were sold and moved piecemeal, others became part of colleges. In 1953 the City of Costa Mesa was incorporated. In June 1955, the former SAAAB property was annexed to the City. For a period of time in the mid-1950s a portion of the Base served as a Nike guided missile training base. The three-battery missile compound had been made operational in January 1956. Two years later, in June 1958, the Air National Guard received a five-acre parcel of land and the remaining 260 acres, including the five-acre air base water facility, was declared surplus and turned over to the GSA. On June 29, 1979, a plaque was dedicated to "all pilots, bombardiers and navigators who trained here that contributed to an early victory in World War II". This plaque was placed on the Air National Guard base, which is the last active duty post on the original location of the SAAAB.

The SAAAB property eventually became the center of the City of Costa Mesa.

The Santa Ana Army Air Base consisted of 1336.102 acres. This was made up of 909.453 acres acquired in fee, by Condemnation and purchase, 420.74 acres acquired by lease 5.771 acres acquired by easement and 0.138 acres acquired by license.
The Army Air Corps used the land as a pilot training facility between March 1942 and October 1944, when it became a redistribution center and convalescent hospital. The base was
built to serve 20,000 personnel. Finally, before it closed in March 1946, it was a discharge station for soldiers returning from the Pacific.
By quitclaim deed dated 8 April 1943, 0.417 acres were conveyed to Albert M. & Rose D. Mungia. On 31 March 1946 the site was declared inactive. On 4 May 1946, title to the site
(1335.685 acres) was passed from the Army to the War Assets Administration (W.A.A.). The former site was sold to various entities Orange Coast College, 32nd Agricultural & Southern California Bible College. The site currently consists of many residential and retail tracts with approximately 2,800 owners.
The site, at present, contains the Orange County Fairgrounds, Costa Mesa City Hall, Orange Coast College, Pacific Amphitheater, Southern California Bible College, Air National
Guard Station and several residential and retail tracts. Some of the original buildings were renovated and are being used by the present owners. The seven tanks are concentrated in a 5 acre area of land owned by the College. The lease was terminated when the fee land was conveyed to the College.

Production Rocket Engine Annex
SITE NAME: Production Rocket Engine Annex, also called Costa Mesa Air Force Plant.

SITE HISTORY: Production Rocket Engine Annex (Costa Mesa AFP) was located on a portion of the land previously occupied by Santa Ana Army Air Base. During World War II, a parcel of land was leased to the Government for construction of the base. In 1946 the Base was declared surplus and the land was purchased by the General Services Administration (GSA) by fee title in 1951. In 1954 a portion (408.66 acres) of the base was transferred by the GSA to the Air Force for the development of the Costa Mesa AFP. The plan for Costa Mesa AFP was to produce rocket engines by North American Aviation for the Air Force. The plant was never built and the parcel was declared surplus in 1956 and transferred to GSA for disposal. In 1960, GSA quitclaimed 49.50 acres to the City of Costa Mesa, 69.90 acres to Newport-Harbor Union High School District, 249.19 acres to the Macco corporation, 20 acres to Costa Mesa Union School District, 1.62 acres to Archdiocese of Los Angeles, and 9.44 acres to the State of California Division of Highways (Caltrans). The remaining 9.01 acres of unimproved land was transferred to the Santa Ana Air National Guard Station.

Currently, the City of Costa Mesa operates and maintains its 49.50 acres which had been developed into TeWinkle Memorial Park.Macco Corporation subdivided its 249.19 acres into single family housing tracts and sold the housing units to private parties. The corporation is no longer in business. The St. John's Church and its grade school operates on the 1.62 acres of property quitclaimed to the Archdiocese of Los Angeles. The school had acquired additional land to make the complex approximately 10 acres parcel. The two school districts are now merged to form Newport-Mesa Unified School District. The Costa Mesa High School and Junior High School and Presidio Elementary School occupy the combined 89.90 acres of the District's property.

Currently, Davis Adult Center leased the Costa Mesa Junior High School facilities from the District. Similarly, Coastline Regional Occupational Program Corp., a non-profit educational facility, leased the Presidio Elementary School building from the District. The Costa Mesa Air National Guard and the right of way of the State Highway 55 (Costa Mesa Freeway) occupy the remainder of the original Costa Mesa AFP property.

Costa Mesa Air National Guard Station
News Article: Air National Guard shuts down: The 222nd Combat Communications Squadron is to move to base north of Sacramento.

COSTA MESA – A formal flag transfer ceremony marked the end of an era Sunday at the California Air National Guard station in Costa Mesa.

One hundred men, women and alumni of the post founded in 1964 gathered for one last reunion as the 222nd Combat Communications Squadron prepares for a move to Beale Air Force Base north of Sacramento.

While the fate of the 8-acre parcel remains unclear as the Army Reserve, National Guard and city of Costa Mesa jockey for position over the prime real estate, veterans reminisced about the many missions accomplished and friendships forged by the “triple deuce.”

Costa Mesa Mayor Alan Mansoor thanked the squadron for providing “a feeling of ongoing patriotism in our community.

UPDATE: The Costa Mesa ANG Station has been transfered to the Army and was redesignated as the Costa Mesa Army Reserve Center and serves as the Headquarters, 311th Sustainment Command (Expeditionary) as well as smaller Army Reserve units.
