Curtiss F11C/BF2C Goshawk

XF11C-2 Test Flight, November 4, 1932

Introduction
The Curtiss F11C Goshawk was a 1930’s biplane that served with the United States Navy. Though it only saw limited successes, it was part of a long line of Curtiss ‘Hawk’ aircraft, built by the Curtiss Aeroplane and Motor Company for the United States military.

Development
In April of 1932, when the Curtiss Company was planning the Model 35B, the United States Navy contracted with Curtiss for an improved version of the Model 34C, or F6C, as the F11C. Several changes were made, including the use of the 600hp Wright R-1510-98 radial engine, single-leg cantilever main undercarriage units, and a slight increase in interplane gap, metal covered control surfaces (as opposed to fabric), and an armament of two 7.62mm Browning machine guns and a hardpoint under the fuselage for a 474lb bomb or a drop tank.
Curtiss designed the aircraft, designated by the company as the Model 64 ‘Goshawk’, while the USN designated it XF11C-1. The aircraft was made of fabric-covered metal framing, and had the wing cell structure of the YP-23, and was delivered in September of 1932.
Before ordering the XF11C-1, the USN had bought a company-owned Model 64A demonstrator, with a Wright R-1820-78 Cyclone, slightly longer main undercarriage legs, and wheels that had low pressure tires, a tailwheel instead of a tailskid, fabric-covered tail control surfaces, and provision for underwing racks for light bombs in addition to the fuselage hardpoint. Flight trials of this XF11C-2 showed a need for some minor changes, and it was regarded as the prototype for the F11C-2, twenty-eight of these being ordered as fighter-bombers (or as the Navy would have it, bomber-fighters) on October 18, 1932. Deliveries began the following February, and were completed in May of 1933.
From March 1934 onwards, the aircraft was revised with a semi-enclosed cockpit and several other modifications before it was designated BFC-2 (BF standing for Bomber-Fighter). The last aircraft in the XF11C-2 contract was converted into the XF11C-3, with the more powerful Wright R-1820-80 engine, and a hand-cranked retractable landing gear.
XF11C-3 Test Flight

Operational History
The only USN units to operate the F11C were VF-1B and VB-6. VF-1B, the famous “High Hat Squadron” was assigned to the USS Saratoga. In March of 1934, when F11C’s were renamed BFC’s, they were renumbered as VB-2B, and subsequently as VB-3B, and used BFC-2’s until February of 1938. VB-6 never actually embarked on their carrier, the USS Enterprise, while using BFC aircraft.
The F11C produced several export versions, known as Hawk I, Hawk II, and Hawk III. The Hawk II, basically a modified XF11C-2, was fitted with a 710hp Wright R-1820F-3 Cyclone radial engine, and carried 94 gallons of fuel, while the Hawk I only carried 50 gallons. Both carried the same armament as the F11C-2. The Hawk II was exported in quantity to Turkey, the first customer who ordered 19 on August 30, 1932. Columbia ordered theirs in October of the same year, also receiving twenty-six versions with twin-floats. The Columbian’s used their Hawk II’s and float-equipped F11C-2’s in the Columbia-Peru War, 1932-33. Nine Hawk II’s were sold to Bolivia, three of which could change between wheels and floats. Four aircraft were sold to Chile, fifty-two to China, four to Cuba, two to Germany, and one to Norway. Twelve were also sold to Thailand, who also obtained a license and built fifty of them locally, designating them as Fighter Type 10.

Chiang Kai-shek

Introduction
Chiang Kai-shek was a political and military leader of China during the 20th Century. He is also known as Jiǎng Jièshí or Jiǎng Zhōngzhèng in Mandarin.
Chiang (since this name is Asian, the family name is said first) was an influential part of the Kuomintang, the Chinese Nationalist Party, and was a very close ally of Sun Yat-sen. He was the commandant of the KMT’s Whampoa Military Academy, and became the leader of the Kuomintang in 1925. He led the Northern Expedition, and eventually became China’s leader. He led China through the Second Sino-Japanese War, which was integrated into World War II and became the China-Burma-India Theater.
After the war, Chiang lost control of China, and lived in exile in Taiwan. Today, there are still mixed feelings towards him – some viewing him with disdain, while others view him as a hero. During the presidency of Chen Shui-bian (2000-2008), hundreds of his statues were taken down all over Taiwan.

Early Life
Chiang Kai-shek was born on October 31, 1887, to a middle-class family living in Xikou, in the Zhejiang Province. He attended a private school at the age of six, and learned the Chinese classics. Chiang’s grandfather died when he was eight, and his father died when he was 9, leaving the family in poverty. Because of this, he adored his mother all the more.
In China, fatherless families had a harder time fitting in to society, and often had people take advantage of them. Chiang often had to tolerate anger and suffering, but his enthusiasm for learning was kindled. He learned many of the Chinese classics between the ages of ten and sixteen. When he was seventeen, he attended a modern school, and then entered the school at Ningbo to learn current events and western law. While there, he became interested in the revolutionary acts of one Sun Yat-sen. This interest would change his life forever.
Since the fighting between warlords in China left the country destabilized and in much debt, Chiang decided on a military career. He started at the Baoding Military Academy in 1906, and in 1907 he went to the Tokyo Shibu Gakko, an Imperial Japanese Army Academy Preparatory School. During this time, he became a supporter of Sun Yat-sen, the leader of the Tongmenghui (the precursor of the Kuomintang).

In 1911, Chiang returned to China and joined in the Wuhan Uprising to overthrow the Qing dynasty, leading the regiment that captured Shanghai. Several sources state that his first personal act of violence happened about this time, when he either instigated or performed an assassination of a member of the Revolutionary Alliance who opposed Sun Yat-sen and Chen Qimei. Chiang returned to Japan after the counter-revolution.
In 1917, when Sun Yat-sen established the Kuomintang in Guangzhou, Chiang served as a military aide. Soon Sun Yat-sen was exiled into Shanghai until he retook Guangzhou with help from mercenaries in 1920. However, the governor of the Guangdong province, Chen Jiongming, came upon a disagreement with Sun, wanting to establish a federalist system in Guangdong. On June 16, 1923, Chen launched an attempted assassination of Sun Yat-sen by shelling his residence. Sun and his wife, Soong Ching-ling, had a narrow escape from machine-gun fire, and were rescued by gunboats commanded by Chiang Kai-shek. This earned Chiang Sun’s trust. Sun finally secured Guangzhou in early 1924, again with help from mercenaries from Yunnan.
In 1924, Sun Yat-sen and China traveled to the Soviet Union to learn military strategy. While there, Chiang met with Leon Trotsky and other Soviet leaders, but concluded that Communism was not good for China. Upon Chiang’s return, he was appointed as the commandant of the new Whampoa Military Academy at Guangzhou. After Sun Yat-sen died on March 12, 1925, Chiang’s became the leader of the KMT after a conflict with Wang Ching-wei.

Leadership of China
In 1926, Chiang launched the Northern Expedition, leading the KMT into Shanghai and Nanjing. He cooperated with the Communists, and received aid from Russia. However, in 1927, Chiang reversed Sun Yat-sen’s policy, and started to fight against the Chinese Communist Party, starting a civil war. On April 12, 1927, Chiang instigated the purging of thousands of suspected Communists and dissidents from Shanghai, and had them massacred. This happened all over China. There were 12,000 people killed in Shanghai alone. These killings drove most of the Communists into the countryside, where the Kuomintang was less powerful. Chiang eventually defeated the CCP, and forced them on the “Long March” to Shensi, in North-West China. By the end of 1927, he served as the head of the Kuomintang and became Generalissimo of all the Chinese Nationalist forces, and his power was virtually unlimited.
Chiang established the Nationalist Government in Nanjing. He carried out major financial reforms, improved the education system, and improved the roads and transportation system. In 1934, he established the New Life Movement, promoting the traditional Confucian values. This was to combat Communist ideology.
After the Japanese invaded Manchuria, Chiang resigned as the Chairman of the National Government, but returned shortly thereafter. He attempted to avoid an all-out war with Japan, but this was not a very popular policy. While attempting to destroy the Communists in 1932, the Japanese advanced on Shanghai and bombarded Nanjing. This disrupted his offensive against the Communists, who were led by Mao Zedong.
In December of 1936, Chiang flew to Xi’an to coordinate a major assault on the Chinese Communist Party’s forces which had retreated to Yan’an. However, his allied commander Zhang Xueliang, who had controlled Manchuria and lost it to the Japanese, disagreed with Chiang about fighting the Communists. On December 12, Zhang and several other collaborators kidnapped Chiang Kai-shek for two weeks to force him to make a “Second United Front” with the Communists against Japan, which Chiang had to accept. After Chiang’s release, Zhang Xueliang was placed under house arrest, and the other generals that assisted in the kidnapping were executed. Chiang kept his side of the agreement to ally with the Communists, but this treaty disintegrated in 1941 when some of Chiang’s troops clashed with CCP troops.
The Second Sino-Japanese War broke out in July of 1937, and in August of that year Chiang sent 600,000 of his best-trained and equipped men to defend Shanghai. They suffered over 200,000 casualties. Though it was a military defeat, Chiang showed the Japanese that they could not capture China, as they claimed, in three months. But still the Japanese pressed inland. In December, Nanjing fell, and Chiang was forced to move the government to Wuhan. When Wuhan fell, the government was moved to Chongqing. He moved his army to the hinterlands so as to bog down the Japanese in the Chinese interior.
Chiang Kai-shek, Soong May-ling (wife), Joseph Stilwell
After the attack on Pearl Harbor in 1941, the Sino-Japanese war merged into the greater conflict of World War II, and Chiang’s international prestige increased. China received financial aid from the United States. General Joseph Stilwell was sent over, and he became the head of the allied forces in the China-Burma-India Theater. Stilwell was very critical of Chiang, arguing that he was an inept leader and ignorant of the fundamentals of modern warfare. Stilwell was accused of being pro-Communist, and was recalled to the US in October of 1944.
Chiang Kai-shek with Franklin D Roosevelt and Winston Churchill in Cairo
During World War II, FDR privately made it clear that he did not want the French to retake French Indochina (modern-day Vietnam, Cambodia, and Laos). When Chiang was offered control of Indochina, Chiang refused. When the war ended, 200,000 Chinese troops under General Lu Han were sent to Indo-China to accept the surrender of the Japanese there. They remained until 1946, when the French returned. The Chinese used the VNQDD, the Vietnamese branch of the KMT, to increase their influence in Indochina, and pressure their opposition. Chiang threatened war with France in response to the French maneuvering their forces against Ho Chi Minh, which forced the French to choose peace. In February of 1946, Chiang forced the French to surrender all of their concessions in China, and renounce the extraterritorial privileges in exchange for the Chinese withdrawing from northern Indochina and allowing the French to reoccupy. The French agreed, and Chiang withdrew his troops in March of 1946.
But Chiang still had a disagreement with the Communists. The United States encouraged peace talks between Chiang and Mao Zedong in Chongqing, but they gave very limited aid to the Nationalists throughout 1946 and 1948. An alleged infiltration of the US government by Chinese communists may have helped in the suspension of aid.

While several political difficulties within the KMT went on, the Communists were pushing into China. In early December of 1949, the Communists laid siege to Chengdu, the last KMT-controlled city on the Chinese mainland. Chiang directed the defense from the Chengdu Military Academy. Before the Communists broke in, Chiang was evacuated to Taiwan, never to return.

In Exile
In Taiwan, Chiang established a dictatorship. He continued to promise to re-conquer China, and landed Chinese guerillas on the Chinese coast. He published his autobiography, Summing Up At Seventy, in 1957.
Chiang Kai-shek in Taiwan, 1966
Chiang’s international position was weakened in 1971 when the United Nations expelled his regime, and accepted the Communists as the government of China. Chiang Kai-shek died on April 5, 1971, in a hospital in Taiwan. A month of mourning was declared, and the Chinese composer Hwang Yau-tai wrote the Chiang Kai-shek Memorial Song. Mainland Chinese newspapers gave the brief headline, “Chiang Kai-shek Has Died”.
Chiang Kai-shek was succeeded as President by Vice President Yen Chia-kan, and as KMT party leader by his son, Chiang Ching-kuo, who retired Chiang Kai-shek’s title of Director General, and instead assumed the position of Chairman. Chiang Ching-kuo became the President after Yen’s term ended three years later.

Kawasaki Ki-10 "Perry"

Kawasaki Ki-10-I "Perry"

Introduction
The Kawasaki Ki-10 (or the Army Type 95 Fighter) was the best and last biplane fighter to serve in the Imperial Japanese Army. It was very maneuverable, and had a big influence on newer monoplane designs. It was built by the Kawasaki Kokuki Kogyo KK, and saw combat in Manchuria and China. The Allied code-name was “Perry”.

Design and Development
The Ki-10 was designed by Takeo Doi, who was the chief designer for Kawasaki. The design was made in response to a requirement issued by the IJA for a new fighter, which was to be equal in performance to that of the Hawker Fury and Boeing P-26 Peashooter. Kawasaki’s first design, an inverted gull-wing monoplane designated Ki-5, was rejected due to a lack of maneuverability. The IJA then ordered Kawasaki to design a high-performance biplane, leading to the design by Takeo Doi.
The Ki-10 was entered into a competition with the Nakajima Ki-11. Powered by a Kawasaki Ha-9-IIa and driving a two-bladed wooden propeller, the Nakajima design was faster. However, the Ki-10 won in maneuverability hands down, and it was accepted over the Ki-11.
The Ki-10 was a sesquiplane (wings of different lengths) design, the wings being braced by struts, and the ailerons only on the upper set of wings. The structure was all-metal and covered with fabric. The armament consisted of two 7.7mm Type 89 machine guns, which were synchronized to fire through the propeller. To increase the speed on the production aircraft, a three-bladed, metal propeller was used, along with flush-head rivets. Production of the Ki-10 began in 1935.
Several variants of the Ki-10 were made. The first production model was the Ki-10-I. Three hundred Ki-10-I’s were built between December 1935 and October 1937. In an attempt to clean up the Ki-10-I, a new version designated Ki-10-I Kai was produced from April till October 1936. This model had a new, low-drag, cantilever undercarriage installed. It also moved the radiator back to a new position between the undercarriage legs. The same engine was used, but the top speed was increased by 12.5mph.
The Ki-10-II was developed while the Ki-10-I was produced. It boasted a longer fuselage and larger wings, and was noticeably more stable. It was ordered into production as the Army Type 95 Model 2. 280 were built between June 1937 and December of 1938. Two Ki-10-II Kai’s were produced by converting two Ki-10-II’s to Ki-10-I Kai’s. They differed in the engine, the Ki-10-II Kai having the Kawasaki Ha-9-IIb, capable of short bursts of 950hp at 12,470ft.

Operational History
The Ki-10 was deployed in Formosa, Korea, Manchuria, and in the beginning campaigns of the Second Sino-Japanese War. An excellent dogfighter, it proved to be capable of taking on many aircraft employed in the Chinese Air Force. But by the time of the Nomonhan Incident with the Soviets (the Battles of Khalkhin Gol), it was largely obsolete.
At the beginning of World War II in the Pacific, the Ki-10 was moved back to training and second-line missions. It was returned to front-line services in January and February 1942, flying short-range patrol and reconnaissance missions in Japan and China. American Intelligence mistakenly believed that it was still in front-line service, and gave it the code-name “Perry”. However, the type was encountered only occasionally over China.

Ki-10-II: Army Fighter Type 95-2; an improved production version of the Ki-10-II prototype, 280 built between June 1937 and December 1938.
Ki-10-I KAI: Prototype Ki-10-I with modifications to the engine and radiator, one built in October of 1936.
Ki-10-II KAI: Prototype – a modification of the Ki-10-II with an 850hp Kawasaki Ha-9-IIb engine; two built in November of 1937.
