The Republic of China Air Force (ROCAF) was formed by the Kuomintang after the establishment of the Aviation Ministry in 1920. As tensions mounted between China and Imperial Japan in the 1930s, a number of smaller Chinese warlord airforce men (including Guangdong Provincial Air Force) and equipment became integrated into the ROCAF in a centralized effort to counter Imperial Japanese military ambitions.

Operations
During the Second Sino-Japanese War (1937–1945), the ROCAF participated in attacks on Japanese warships on the eastern front and along the Yangtze river and interdiction and close-air support during the Battle of Shanghai in 1937. The initially Chinese frontline fighter aircraft were mainly Curtiss Hawk IIs, Hawk IIIs and Boeing P-26Cs. These engaged Japanese fighters in many major air battles beginning on 14 August 1937, when Imperial Japanese Navy warplanes raided Chienchiao airbase; "814" has thus become known as "Air Force Day". Chinese Boeing P-26/281 fighters engaged Japanese Mitsubishi A5M fighters in the world's first dogfight between all-metal monoplane fighters. A unique mission in April 1938 saw two Chinese Martin B-10 bombers fly a mission over Japan, dropping only anti-war leaflets over the Japanese cities of Nagasaki and Saga. It was a war of attrition for the Chinese pilots, as many of their most experienced ace fighter pilots, such as Lieutenant Liu Tsui-Kang and Colonel Kao Chih-Hang, were lost. Six months into the war, which is considered the beginning of World War II in Asia, the Chinese Air Force inventory of frontline American Hawk IIs and IIIss and P-26Cs were superseded by faster and better armed Polikarpov I-15s and I-16s as support from the Soviet Union grew and American support faded.

Through attrition and loss of their most experienced fighter pilots in the first half of the Second Sino-Japanese War, the Republic of China Air Force ultimately suffered irreversible losses in combat against the Japanese, and by the beginning of 1942 the ROCAF was practically annihilated by Japanese aircraft, particularly with the introduction of the Mitsubishi A6M Zero. The ROCAF was eventually supplemented with the establishment of the American Volunteer Group (known as the "Flying Tigers") with heavily armed and armored Curtiss P-40 Warhawks, and subsequently rebuilt each year following Imperial Japan's attack on Pearl Harbor with new aid and vigor from the United States.

The Sino-Japanese War started on 7 July 1937. At that time, Chinese sources estimated the Japanese could field approximately 600 aircraft (from a total of 1,530) against China's 230 combat aircraft. During the first phase up to 1939, aerial bombing of enemy bomber formations was tried with indifferent results, and leaflet-dropping raids carried out over Japanese cities.

The Japanese bombing raids were also fiercely contested, sometimes with significant Japanese losses. After suffering heavy losses in the Battle of Wuhan in October 1938, most air force units were withdrawn for reorganisation and training.

The ROC Air Force was reconstituted into seven Groups, one separate Squadron and four Volunteer Groups. In 1939, after the USSR concluded a non-aggression pact with Germany, the Soviet Volunteer Group was withdrawn. By the end of 1941, the air force had 364 operational aircraft. Up to 100 of these were P-40Bs operated by the American Volunteer Group.[1] U.S. replacement aircraft began to arrive in March 1942. They included A-29s, P-40s, P-43s,[2]

In 1944, the USAAF Fourteenth Air Force commenced joint operations in the China theatre.[citation needed] By this time the Chinese Air Force was mostly equipped with current operational aircraft types and was superior in all respects to the opposing Japanese air forces which remained.

Foreign aid
Soviet Union
From 1937 to the beginning of 1941, the Soviet Union served as the primary supplier to the ROCAF, and from October 1937 to January 1941, a total of 848 aircraft in 13 batches were ordered by the Chinese government and were supplied on credit, worth roughly 200 million dollars. In addition, there were 37 aircraft transferred to Chinese when Soviet force withdrew from China after the signing of Soviet–German Non-Aggression Pact. These aircraft included 563 fighters, including 252 I-152, 75 I-153, 132 I-16 Type 10, 75 I-16 Type 17 and rest being I-15 bis, which was not part of the purchase in the 13 batches. Also included were 322 bombers, including 179 SB-2M-100A, 100 SB-2M-103 24 DB-3, 6 TB-3 and 13 SB that were not part of the purchase in the 13 batches). Also included in the 13-batch purchase were 5 UT-1 trainers. However, of the 250–300 combat aircraft supplied annually, only a few dozen would survive through the end of the year.

United States
While the USSR provided most of the military aircraft to Chiang Kai-shek in the late 1930s, many early Chinese aircraft were supplied by the American Curtiss Aeroplane and Motor Company. In 1937 the Hawk II and Hawk III biplanes comprised the backbone of Chinese fighter aviation. These were soon followed by the Hawk 75 monoplane. The demonstration model Hawk 75N, with non-retractable landing gear was purchased in 1938 and became the personal aircraft of the American advisor to the Aviation Committee, Claire Chennault who oversaw training and lobbied for the procurement of American aircraft.

The entry of the USA into the war with Japan at the end of 1941 led to the receipt of Lend-Lease equipment from the United States, including aircraft. American Lend-Lease aviation equipment had already begun to arrive in China as early as the middle of 1941, though that includes the first shipments before January 1942 which arrived under the guise of purchases. Including previously purchased American aircraft, US soon replaced USSR as the largest supplier for the Chinese Nationalist air force during the war (Including the Second Sino-Japanese War that actually broke out in 1931 when Japan invaded Manchuria).

Retraining on American aircraft occurred for the most part in India. (Karachi and other cities), where Chinese pilots were sent both as groups and as entire units. As early as the end of 1941 Chinese pilots, mainly recently graduated from flight schools, began to be sent to the US for longer training and mastery of American aircraft.

The first American P-43A fighters were received by the 4th Air Group (21st – 24th Squadrons) in March 1942. They retrained in Kunming, but for the new aircraft the pilots sequentially flew in small groups to India. On 24 April the deputy commander of the 24th Squadron, Wu Zhenhua, crashed on the flight to Kunming. On 12 May, Chen Lokun, the flight commander of the 24th Squadron was killed during a training flight, crashing into a tree during landing. In July for unclear reasons the P-43 of the 4th Air Group commander, Zheng Shaoyu, caught fire in the air and the pilot was killed. On 3 August 1942 during a training flight the deputy group commander Chen Sheng crashed. A similar series of crashes accompanied the mastery by the Chinese of almost every new machine. (It is notable that in Chinese sources the family names are given only of the perished commanders of various ranks, while the losses amongst the line pilots are hardly even noted.) Concluding their conversion to the P-43A in early August 1942, the group returned to Chengdu.

In February 1943, preparing for transition to the new American air equipment, the Chinese transferred to India the primary training groups from their flight schools. Only training for reconnaissance and photography continued to be carried out in China. In March 1945 the cadets completing primary training in India were sent to America to train further. By that time the number of cadets dispatched had reached 1224, of whom 384 managed to return to China and participate in combat. In all, from 1942 to 1945 420 training aircraft were sent from the US to China through India, including 20 AT-6, 8 AT-7, 15 AT-17, 150 PT-17, 127 PT-19, 70 PT-22, and 30 BT-13, and also 10 Beechcraft D-17 medical aircraft.

Domestic assembly
While the modified Hawk 75M with retractable landing gear was created specially for China, it was not widely used in the war against the Japanese, in spite of the fact that 30 aircraft, and 82 kits for assembly were delivered in the summer and autumn of 1938. It was planned to assemble the Hawk in a factory operated by the Central Aircraft Manufacturing Company, which had been evacuated from Hankou to Loiwing. The latter location, not far from the Burmese border on the eastern bank of the Ruiluqiang River in Yunnan Province, at that time seemed protected from Japanese attacks, but technical difficulties plagued the actual assembly of the Hawk 75 in that location. Although the Japanese had not bombed the factory, only eight machines were assembled by October 1940. The fate of the remaining kits is unknown.

Following the failure of Hawk 75 production, the CAMCO factory planned to organize assembly of the export version of the Curtiss-Wright CW-21 Demon, light fighter. Three aircraft and 32 sets of components were ordered from the USA. The factory at Loiwing worked until April 1942, when on account of Japanese attacks it had to be evacuated to Kunming, while its American personnel set up shop in India. From 1943 to 1946 the aircraft factory, which was dispersed in the ravines neighboring Kunming, assembled an experimental series of nine fighter monoplanes, probably from components of the Hawk 75M and 75A-5, and CW-21. To a degree they were similar to the American prototypes and their further fate is unknown. In western sources the first example figures under the designation Chu X-PO.

Chapter III - From Flying to Aviation Cadets in World War II
The onset of World War II and
the mobilization of millions of
Americans reshaped the military services
and, over time, was the crucible that
proved the need for an independent air
force in the United States.61 As the
international crisis deepened, the Army
planned for ever-increasing numbers of
pilots and fundamentally changed the
flying cadet program. By 25 March
1941, almost nine months before the
American entry into World War II,
Congress authorized the production of
30,000 pilots annually, with over 100
training bases. The Army Aviation
Cadet Act, Public Law (PL) 97 signed
on 3 June 1941, created the grade of
“aviation cadet” as a substitute for the
grade of “flying cadet” established 22
years earlier. The law specified that
“male citizens of the United States may
enlist as aviation cadets, and enlisted
men in the Regular Army may be
appointed by the Secretary of War as
aviation cadets.” Cadets agreed to
accept commissions as second
lieutenants in the Air Corps Reserve and
serve three years on active duty upon
completion of training, unless released
from service by the War Department
earlier. At the end of the three-year
period, the officers would be promoted
to first lieutenant, again in the reserve.
Base pay remained $75, as it had been in
1919, with a ration allowance of $1 per
day. As under the previous legislation,
cadets in flying programs qualified for
flight pay; as a new perk, all aviation
cadets received a $150 uniform
allowance upon the successful
completion of training. Reserve officers
who were not offered commissions in
the Regular Army and released from
active duty were given a lump sum equal
to $500 for each complete year of
service. Another new benefit included
government life insurance in the amount
of $10,000 paid for by the government
during initial training. After
commissioning, the officers could
continue the coverage at their own
expense. Initially, the Army simply
discharged aviation cadets who washed
out of training. After 1 February 1942,
the War Department required aviation
cadets to enlist as privates in the Air
Corps. Thereafter, if a cadet was
eliminated from his training program, he
reverted to the rank of private and could
be reassigned according to the needs of
the service. In November 1942, the
active duty commitment was extended
so that enlistments lasted for the duration
of the war plus six months.62 The three
Air Corps Training Centers established
in 1940 were realigned under the newly
established Air Corps Flying Training
Command (ACFTC) in January 1942.

Later, in July 1943, the ACFTC would
become the Army Air Forces Training
Command, responsible for both flying
training and technical training
programs.63
PL 97 did not set age or
education qualifications, but the Army
would adjust its requirements throughout
the war according to its manpower
needs. Less restrictive qualifications
would allow more aviation cadets to
enter training, more restrictive
qualifications slowed the training
pipeline. Almost immediately following
the outbreak of World War II, the Army
Air Forces (AAF), established in June
1941, dropped the requirement that
aircrew trainees (pilots, navigators, and
bombardiers) had to have college
experience. Strict educational
qualifications, however, remained
throughout the war for those aviation
cadets entering ground duty programs.
In a 28 July 1941 memorandum,
officials outlined three general classes,
or tracks, for aviation cadets: “aviation
cadet (pilot and bombardier),” “aviation
cadet (navigator, non-pilot, flying),” and
“aviation cadet (ground duty, as
meteorologist and engineer).” Officials
believed that each of the training
programs would be of approximately the
same duration. In actual practice, by the
fall of 1941 the aviation cadet ground
duty courses varied in length from 10
weeks to 9 months, while pilot training
lasted about 7 ½ months. While there
had been sentiment to withhold the
commissions of the ground program
graduates until they had completed the
same length of service as pilot trainees,
the Secretary of War ruled that aviation
cadets should be commissioned upon the
completion of their training programs,
regardless of length.64
Recruiting brochures spelled out
application procedures and outlined
training programs. Aviation Cadet
Training for the Army Air Forces,
published in April 1943, for example,
emphasized the urgency of the
requirement—“Our nation’s future
depends upon command of the air. The
future of freedom and liberty
everywhere is in the hands of our
youth.” Men between the age of 18 and 
33
26 could apply for aircrew positions, and
those as young as 17 could apply with
the consent of their parents. The April
1943 publication spelled out the need for
meteorologists, noting that those up to
age 30 could apply.65
By the end of World War II,
nearly 200,000 men had been trained as
Army pilots, along with 100,000
bombardiers and navigators, and another
20,000 ground duty officers.
Unfortunately, the historical record does
not accurately detail how many of these
were aviation cadets. The AAF’s
Statistical Control Division did,
however, provide a quarterly total of
aviation cadets in training through
World War II. In December 1941, only
17,614 cadets were in training, 16,733 of
them in flying training programs and the
rest in ground duty training. By the end
of the next year, this had ballooned to
94,003 aviation cadets in training,
89,973 in flying programs and 4,030 in
ground duty programs. The highest
quarterly total, 114,336, was reached in
December 1943, with over 109,000 of
those aviation cadets in aircrew training
programs. By December 1944, the
training drawdown was well underway
and 38,929 cadets were in training, only
133 of whom were in ground duty
programs. To manage the cadet
programs, the Office of the Chief of the
Air Corps established a Flying Cadet
Section early in 1940, renamed the
Aviation Cadet Section with the passage
of PL 97. Subsequently, the
Headquarters of the Army Air Forces
absorbed the Aviation Cadet Branch.66
Aircrew Qualification – The
Classification Battery
To meet the ever-growing need for pilots
and aircrew, in January 1942, the AAF
abandoned the requirement that cadets in
the flying programs had to have two
years of college experience. Aviation
Cadet Examining Boards administered a
three-part battery of tests, in addition to
a rigid physical examination, to help
identify those who might make the best
pilots, navigators, and bombardiers. The
first part of what was being called the
“classification battery” was the Aviation
Cadet Qualifying Exam (ACQE).
Designed to measure the candidate’s
comprehension, judgment, math skills,
mechanical ability, alertness, and
leadership qualities, the ACQE replaced
the education test used in earlier years to
measure the candidate’s general
knowledge and intellectual skills.
Instead of being used to judge
educational qualifications for those who
did not possess the required school
transcripts, the ACQE better predicted
qualification for aircrew training and
duty as an air force officer. A
psychomotor test measured eye-hand
coordination, reflexes, ability to perform
under pressure, and visual acuity.
Finally, the candidates underwent an
interview with a trained psychologist.

Stanines
After completing all three of the
tests, officials scored the results on a
nine-point scale. Called a standard nine,
or “stanine,” this composite score
evaluated physical, psychomotor, and
psychological attributes in an attempt to
best match those entering the
comprehensive training programs to the
needs of the service. Initially, pilots and
bombardiers required only the lowest
stanine, 1, to qualify; in December 1942,
air force officials raised this to 3. While
pilot candidates only needed a low
stanine score, reflecting the enormous
need for aviation cadets to enter pilot
training, navigator candidates typically
required the highest stanine scores.
Initially, navigator candidates needed a 5
stanine to qualify for training, and
officials raised this to 7 in November
1943. Bombardier candidates needed a
6 stanine by mid-July 1943 to qualify for
training. In February 1944, AAF
officials had pretty much leveled the
stanines for the aircrew training
programs. At that time, navigator
candidates needed to score 6,
bombardiers and pilots 5, to qualify for
training. Students who had high stanines
typically graduated at higher rates than
those with lower scores. A faculty board
at the training centers also considered
the trainees’ personal preferences in
making the assignments. However,
because 97 percent of the cadets wanted
to be pilots, the classification procedure
first took into consideration the type of
aircrew training needed by the service,
then the stanine score, and finally
individual preferences.67
As spelled out in the Aviation
Cadet Manual of 1942, those who would
train as fighter pilots had to be between
64” and 69” tall, while other pilots could
be as tall as 76”. Navigators and
bombardiers had to measure between
60” and 76” in height. The allowable
weight was adjusted for height and
weight, but no one who weighed more
than 160 would be accepted into fighter
pilot training and no one over 200 would
be accepted into any of the aircrew
programs. In July 1943, AAF officials
relaxed the physical qualifications for
aircrew members somewhat. Instead of
requiring 20/20 vision, for example,
20/30 was acceptable so long as it was
correctible to 20/20. In addition to
eliminating the requirement for two
