97-600: The museum officially opened on 12 September 2009. The museum states its mission as: The Jet Aircraft Museum (JAM) will acquire, preserve, maintain, display and fly jet aircraft of the Canadian Forces from the DeHavilland Vampire to present day and future aircraft. The museum has indicated its intention "JAM will strive to maintain four or more of each type as flying aircraft with a flight of four reflecting authentic Canadian Forces paint schemes." The museum has listed

194-508: A Joint Security Area at Panmunjom . The conflict caused more than 1 million military deaths and an estimated 2 to 3 million civilian deaths, a larger proportion of civilian deaths than in World War II or the Vietnam War . Alleged war crimes include the mass killing of suspected communists by Seoul and the torture and starvation of prisoners of war by Pyongyang. North Korea became one of

291-557: A future independent state. Due to political disagreements and influence from their backers, the zones formed their own governments in 1948. The DPRK was led by Kim Il Sung in Pyongyang , and the ROK by Syngman Rhee in Seoul ; both claimed to be the sole legitimate government of all of Korea and engaged in border clashes as internal unrest was fomented by communist groups in the south. On 25 June 1950,

388-501: A general attack across the 38th parallel, rather than a limited operation in Ongjin. Kim was concerned that South Korean agents had learned about the plans and that South Korean forces were strengthening their defenses. Stalin agreed to this change. While these preparations were underway in the North, there were clashes along the 38th parallel, especially at Kaesong and Ongjin, many initiated by

485-424: A maximum thrust of 28.9 kN (2,950 kgp / 6,500 lbf) thrust. During July 1950, the second prototype, 18102 , performed its first flight. On 5 April 1951, the second prototype was lost in an accident that killed test pilot Bruce Warren. According to aviation author James Dow, this loss resulted in the programme being placed on indefinite hold and questions raised over Avro Canada's competency. In response to

582-579: A national political constitution on 17 July and elected Syngman Rhee as president on 20 July. The Republic of Korea (South Korea) was established on 15 August 1948. In the Soviet-Korean Zone of Occupation, the Soviets agreed to the establishment of a communist government led by Kim Il Sung. The 1948 North Korean parliamentary elections took place in August. The Soviet Union withdrew its forces in 1948 and

679-534: A pair of Rolls-Royce Avon RA 3 turbojet engines. Both pre-production and production series aircraft were powered by the domestically-developed Avro Orenda engine instead. Flight testing proved the CF-100 to possess a relatively short takeoff run and a high climb rate, making it well suited to its role as an interceptor. On 18 December 1952, Squadron Leader Janusz Żurakowski , the Avro company chief development test pilot, took

776-598: A telegram. Mao accepted the decision made by Kim and Stalin to unify Korea but cautioned Kim over possible US intervention. Soviet generals with extensive combat experience from World War II were sent to North Korea as the Soviet Advisory Group. They completed plans for attack by May and called for a skirmish to be initiated in the Ongjin Peninsula on the west coast of Korea. The North Koreans would then launch an attack to capture Seoul and encircle and destroy

873-411: A two-seat fighter, to be crewed by a pilot and navigator, it would adopt two powerful engines along with a relatively advanced radar set and fire control system housed in its nose that would enable the aircraft to be operated in all-weather or night conditions. These requirements were formalized by a RCAF specification that was issued during 1946. According to RCAF Air Marshal Wilfred Curtis , there

Specifically, the service had identified a need for a new jet-powered interceptor /fighter aircraft that would be able to patrol the vast areas of Canada's north and operate in all weather conditions. Envisaged as

While there was hesitance by some in the US government to get involved, considerations about Japan fed into the decision to engage on behalf of South Korea. After the fall of China to the communists, US experts saw Japan as the region's counterweight to the Soviet Union and China. While there

1164-600: The Avro Canada CF-103 , an advanced derivative of the CF-100 that adopted a swept wing and was capable of transonic speeds, was in development, but was terminated. Further development of these concepts ultimately led to the Avro Canada CF-105 Arrow . During 1981, all of the remaining RCAF CF-100s were withdrawn from service, having been succeeded in the electronic warfare role by the CC-117 Falcon . Amid

The aircraft owned by the museum are: CF-100 Canuck The Avro Canada CF-100 Canuck (affectionately known as the "Clunk") is a Canadian twinjet interceptor / fighter designed and produced by aircraft manufacturer Avro Canada . It has

1358-470: The Cold War between the Soviet Union and US. Fighting ended in 1953 with an armistice but no peace treaty , leading to the ongoing Korean conflict characterized by phases of diplomacy and confrontation. After the end of World War II in 1945, Korea, which had been a Japanese colony for 35 years, was divided by the Soviet Union and the US into two occupation zones at the 38th parallel , with plans for

1455-516: The Cold War , the CF-100 was typically deployed at both NATO bases in Europe and in North America as part of North American Aerospace Defense Command (NORAD). In addition to the type's use by frontline squadrons , it was also supplied to operational training units and frequently used for other secondary duties, including aerial reconnaissance and electronic warfare roles. During the early 1950s,

1552-526: The Korean People's Army (KPA), equipped and trained by the Soviets, launched an invasion of the south. In the absence of the Soviet Union's representative, the UN Security Council denounced the attack and recommended member states to repel the invasion. UN forces comprised 21 countries, with the US providing around 90% of military personnel. Seoul was captured on 28 June, and by early August,

1649-697: The North Atlantic Treaty Organization (NATO), four CF-100 squadrons were based in Europe with 1 Air Division ; for some time, the CF-100 was the only NATO fighter that was capable of operating in zero visibility and poor weather conditions. Around the start of the Korean War in the early 1950s, the United States Air Force (USAF) found itself in urgent need of a jet-propelled, all-weather, interdiction / surveillance aircraft . This urgency

1746-660: The Republic of Korea Army (ROKA) and its allies were nearly defeated, holding onto only the Pusan Perimeter in the peninsula's southeast. On 15 September, UN forces landed at Inchon near Seoul, cutting off KPA troops and supply lines. UN forces broke out from the perimeter on 18 September, re-captured Seoul, and invaded North Korea in October, capturing Pyongyang and advancing towards the Yalu River —the border with China. On 19 October,

1843-654: The atomic bombing of Hiroshima . By 10 August, the Red Army had begun to occupy the north of Korea. On 10 August in Washington , US Colonels Dean Rusk and Charles H. Bonesteel III were assigned to divide Korea into Soviet and US occupation zones and proposed the 38th parallel as the dividing line. This was incorporated into the US General Order No. 1 , which responded to the Japanese surrender on 15 August. Explaining

1940-639: The 38th parallel and establishing English as the official language during military control. On 8 September, US Lieutenant General John R. Hodge arrived in Incheon to accept the Japanese surrender south of the 38th parallel. Appointed as military governor, Hodge directly controlled South Korea as head of the United States Army Military Government in Korea (USAMGIK 1945–48). In December 1945, Korea

2037-515: The 38th parallel. Armistice negotiations began in July 1951, but dragged on as the fighting became a war of attrition and the north suffered heavy damage from U.S. bombing . Combat ended on 27 July 1953 with the signing of the Korean Armistice Agreement , which allowed the exchange of prisoners and created a 4-kilometre (2.5 mi) wide Demilitarized Zone (DMZ) along the frontline, with

2134-588: The 53 aircraft that were delivered to the Belgian Air Force. Although originally designed for only 2,000 flight hours, it was found that the Canuck's airframe could serve for over 20,000 hours before needing to be withdrawn. The Belgian aircraft were either scrapped after storage or written off in crashes. Consequently, though the Canadian CF-100 would be replaced in its front line role by the faster CF-101 Voodoo ,

2231-594: The CF-100 Mk ;4 prototype up to Mach 1.10 in a dive from 14,000 m (45,000 ft), making the type the first straight-winged jet aircraft to achieve controlled supersonic flight. The CF-100 principally served with the Royal Canadian Air Force and Canadian Armed Forces ; it was also procured in small numbers by Belgium to equip the Belgian Air Component . Introduced during 1952 amid

2328-640: The CF-100 for the Belgian Air Force . Additional efforts were made to sell the Canuck to several other nations, including the United States , but no other export customers for the type would be secured. Dow reasoned that the Canuck's poor overseas sales performance caused officials to have little confidence for exporting other aircraft, including the CF-105 Arrow. During the type's production life, 692 CF-100s of different variants were manufactured, including

2425-423: The CF-100's development. At one stage Frost, along with Avro's Chief Aerodynamacist Jim Chamberlin , extensively reworked the original design of the fuselage. On 17 May 1949, in response to the programme's progress, an additional agreement was reached to produce ten pre-production fighters along with 30 Avro Orendas , an indigenously-developed turbojet engine. The CF-100 Mark 1 prototype, 18101 , emerged from

2522-508: The CF-100. Five pre-production Mk 2 test aircraft (serial numbers 18103 - 18107 ) were produced, all fitted with Orenda 2 engines; one was fitted with dual controls and designated a Mk 2T trainer. According to pilot Jacqueline Cochran , the Orenda engine responded noticeably smoother than any of the British or American-built jet engines that she had previously flown. Initial teething issues with

2619-401: The Canuck continued to serve with 414 Squadron of the Canadian Forces, based at CFB North Bay , Ontario ; during its later years, the type was tasked with aerial reconnaissance , training and electronic warfare missions. It was finally withdrawn from service during 1981. After the CF-100 was retired, a number of aircraft still remain across Canada (and elsewhere) as static displays. During

2716-406: The Canuck was affectionately known as the "Clunk", the name has been attributed to the noise produced by the forward landing gear during retraction into its well after takeoff. Another common, less attractive, nickname was the "Lead Sled", a reference to its heavy controls and general lack of maneuverability, a nickname that was shared with a number of other 1950s aircraft. Others included CF-Zero,

2813-670: The Chinese People's Volunteer Army (PVA) crossed the Yalu and entered the war on the side of the north. UN forces retreated from North Korea in December, following the PVA's first and second offensive . Communist forces captured Seoul again in January 1951 before losing it to a UN counter-offensive two months later. After an abortive Chinese spring offensive , UN forces retook territory roughly up to

2910-687: The Chinese Civil War, while US forces remained stationed in South Korea. By spring 1950, he believed that the strategic situation had changed: PLA forces under Mao Zedong had secured final victory, US forces had withdrawn from Korea, and the Soviets had detonated their first nuclear bomb , breaking the US monopoly. As the US had not directly intervened to stop the communists in China, Stalin calculated they would be even less willing to fight in Korea, which had less strategic significance. The Soviets had cracked

3007-687: The Chinese PLA during the war. North Korea also provided the Chinese Communists in Manchuria with a safe refuge for non-combatants and communications with the rest of China. The North Korean contributions to the Chinese Communist victory were not forgotten after the creation of the People's Republic of China (PRC) in 1949. As a token of gratitude, between 50,000 and 70,000 Korean veterans who served in

While flown in the North American theatre, the CF-100 would typically retain a natural metal finish; however, those flying overseas were given a British-style disruptive camouflage scheme: dark sea gray and green on top, light sea gray on

3201-474: The North. On 28 June, Rhee ordered the massacre of suspected political opponents in his own country. In five days, the ROK, which had 95,000 troops on 25 June, was down to less than 22,000 troops. In early July, when US forces arrived, what was left of the ROK was placed under US operational command of the United Nations Command . The Truman administration was unprepared for the invasion. Korea

3298-622: The PLA were sent back along with their weapons, and they later played a significant role in the initial invasion of South Korea. China promised to support the North Koreans in the event of a war against South Korea. By 1948, a North Korea-backed insurgency had broken out in the southern half of the peninsula. This was exacerbated by the undeclared border war between the Koreas, which saw division-level engagements and thousands of deaths on both sides. The ROK

3395-547: The ROK had 98,000 soldiers (65,000 combat, 33,000 support), no tanks (they had been requested from the U.S. military, but requests were denied), and a 22-plane air force comprising 12 liaison-type and 10 AT-6 advanced-trainer airplanes. Large U.S. garrisons and air forces were in Japan, but only 200–300 U.S. troops were in Korea. At dawn on 25 June 1950, the KPA crossed the 38th parallel behind artillery fire. It justified its assault with

3492-524: The ROK. The final stage would involve destroying South Korean government remnants and capturing the rest of South Korea, including the ports. On 7 June 1950, Kim called for a Korea-wide election on 5–8 August 1950 and a consultative conference in Haeju on 15–17 June. On 11 June, the North sent three diplomats to the South as a peace overture, which Rhee rejected outright. On 21 June, Kim revised his war plan to involve

3589-519: The ROKA launched a three-pronged assault on the insurgents in South Cholla and Taegu . By March 1950, the ROKA claimed 5,621 guerrillas killed or captured and 1,066 small arms seized. This operation crippled the insurgency. Soon after, North Korea made final attempts to keep the uprising active, sending battalion-sized units of infiltrators under the commands of Kim Sang-ho and Kim Moo-hyon. The first battalion

3686-481: The South Korean interior intensified; persistent operations, paired with worsening weather, denied the guerrillas sanctuary and wore away their fighting strength. North Korea responded by sending more troops to link up with insurgents and build more partisan cadres; North Korean infiltrators had reached 3,000 soldiers in 12 units by the start of 1950, but all were destroyed or scattered by the ROKA. On 1 October 1949,

3783-470: The South from 5,000 to 1,000. However, Kim Il Sung believed widespread uprisings had weakened the South Korean military and that a North Korean invasion would be welcomed by much of the South Korean population. Kim began seeking Stalin's support for an invasion in March 1949, traveling to Moscow to persuade him. Stalin initially did not think the time was right for a war in Korea. PLA forces were still embroiled in

3880-435: The South, armed by the U.S. military with mostly small arms, but no heavy weaponry. Several generals, such as Lee Kwon-mu , were PLA veterans born to ethnic Koreans in China. While older histories of the conflict often referred to these ethnic Korean PLA veterans as being sent from northern Korea to fight in the Chinese Civil War before being sent back, recent Chinese archival sources studied by Kim Donggill indicate that this

3977-693: The South. The ROK was being trained by the US Korean Military Advisory Group (KMAG). On the eve of the war, KMAG commander General William Lynn Roberts voiced utmost confidence in the ROK and boasted that any North Korean invasion would merely provide "target practice". For his part, Syngman Rhee repeatedly expressed his desire to conquer the North, including when US diplomat John Foster Dulles visited Korea on 18 June. Though some South Korean and US intelligence officers predicted an attack, similar predictions had been made before and nothing had happened. The Central Intelligence Agency noted

4074-720: The Soviet Union would not move against US forces in Korea. The Truman administration believed it could intervene in Korea without undermining its commitments elsewhere. On 25 June 1950, the United Nations Security Council unanimously condemned the North Korean invasion of South Korea with Resolution 82 . The Soviet Union, a veto-wielding power , had boycotted Council meetings since January 1950, protesting Taiwan 's occupation of China's permanent seat . The Security Council, on 27 June 1950, published Resolution 83 recommending member states provide military assistance to

4171-741: The UK, and the US decided that "in due course, Korea shall become free and independent". At the Tehran Conference in 1943 and the Yalta Conference in February 1945, the Soviet Union promised to join its allies in the Pacific War within three months of the victory in Europe . Germany officially surrendered on 8 May 1945, and the USSR declared war on Japan and invaded Manchuria on 8 August 1945, two days after

4268-657: The US in 1949. With the end of the war with Japan , the Chinese Civil War resumed in earnest between the Communists and the Nationalist -led government. While the Communists were struggling for supremacy in Manchuria, they were supported by the North Korean government with matériel and manpower. According to Chinese sources, the North Koreans donated 2,000 railway cars worth of supplies while thousands of Koreans served in

4365-615: The USAMGIK declared martial law . Citing the inability of the Joint Commission to make progress, the US government decided to hold an election under UN auspices to create an independent Korea. The Soviet authorities and Korean communists refused to cooperate on the grounds it would not be fair, and many South Korean politicians boycotted it. The 1948 South Korean general election was held in May. The resultant South Korean government promulgated

4462-426: The Zilch, and the Beast, all references to an aircraft many pilots considered less glamorous than RCAF day fighters like the Canadair Sabre . Operationally, many CF-100s functioned under the US–Canadian North American Air Defense Command (NORAD), which protected North American airspace from Soviet intruders, particularly the threat posed by nuclear-armed bombers . Additionally, between 1956 and 1962, as part of

4559-420: The area to that end. The Truman administration still refrained from committing troops on the ground, because advisers believed the North Koreans could be stopped by air and naval power alone. The Truman administration was uncertain whether the attack was a ploy by the Soviet Union, or just a test of US resolve. The decision to commit ground troops became viable when a communiqué was received on 27 June indicating

4656-428: The area". As Rusk's comments indicate, the US doubted whether the Soviets would agree. Joseph Stalin , however, maintained his wartime policy of cooperation, and on 16 August, the Red Army halted at the 38th parallel for three weeks to await the arrival of US forces. On 7 September 1945, General Douglas MacArthur issued Proclamation No. 1 to the people of Korea, announcing US military control over Korea south of

4753-417: The border, starting in May 1949. Border clashes between South and North continued on 4 August 1949, when thousands of North Korean troops attacked South Korean troops occupying territory north of the 38th parallel. The 2nd and 18th ROK Infantry Regiments repulsed attacks in Kuksa-bong, and KPA troops were "completely routed". Border incidents decreased by the start of 1950. Meanwhile, counterinsurgencies in

4850-443: The border, these guerrillas launched an offensive in September aimed at undermining the South Korean government and preparing the country for the KPA's arrival in force. This offensive failed. However, the guerrillas were now entrenched in the Taebaek-san region of the North Gyeongsang Province and the border areas of the Gangwon Province . While the insurgency was ongoing, the ROKA and KPA engaged in battalion-sized battles along

4947-516: The bottom. During his Avro Canada years, the Chief Development Pilot, S/L Żurakowski , continued to fly as an aerobatic display pilot, with spectacular results, especially at the 1955 Farnborough Airshow where he displayed the CF-100 in a "falling-leaf." He was acclaimed again as the "Great Żura" by many aviation and industry observers who could not believe a large, all-weather fighter could be put through its paces so spectacularly. His performance has been credited with Belgium 's decision to purchase

5044-487: The choice of the 38th parallel, Rusk observed, "Even though it was further north than could be realistically reached by U. S. [ sic ] forces in the event of Soviet disagreement ... we felt it important to include the capital of Korea in the area of responsibility of American troops". He noted that he was "faced with the scarcity of U.S. forces immediately available and time and space factors which would make it difficult to reach very far north before Soviet troops could enter

5141-434: The claim ROK troops attacked first and that the KPA were aiming to arrest and execute the "bandit traitor Syngman Rhee". Fighting began on the strategic Ongjin Peninsula in the west. There were initial South Korean claims that the 17th Regiment had counterattacked at Haeju; some scholars argue the claimed counterattack was instead the instigating attack, and therefore that the South Koreans may have fired first. However,

Darling, which had previously conducted tests at Namao Air Base , Alberta , were part of the climatic detachment of Central Experimental and Proving Establishment ; testing commenced during the following month. In March 1956, a batch of four CF-100 Canucks were dispatched to Eglin AFB to conduct comparative armament trials, where

5335-466: The codes used by the US to communicate with their embassy in Moscow , and reading dispatches convinced Stalin that Korea did not have the importance to the US that would warrant a nuclear confrontation. Stalin began a more aggressive strategy in Asia based on these developments, including promising economic and military aid to China through the Sino-Soviet Treaty of Friendship, Alliance and Mutual Assistance . In April 1950, Stalin permitted Kim to attack

In the fall of 1949, two PLA divisions composed mainly of Korean-Chinese troops (the 164th and 166th ) entered North Korea, followed by smaller units throughout the rest of 1949. The reinforcement of the KPA with PLA veterans continued into 1950, with the 156th Division and several other units of

Work was initially overseen by Edgar Atkin, Avro Canada's Chief Engineer; a key contributor to the programme was ex- de Havilland aircraft designer John Frost , who was appointed chief design engineer for military projects and thus responsible for

5626-406: The country. The Provisional Government of the Republic of Korea was founded in 1919 in Nationalist China . It failed to achieve international recognition, failed to unite the nationalist groups, and had a fractious relationship with its US-based founding president, Syngman Rhee . From 1919 to 1925 and beyond, Korean communists led internal and external warfare against the Japanese. In China,

5820-419: The distinction of being the only Canadian-designed fighter to enter mass production . Work commenced in October 1946 in response to a Royal Canadian Air Force (RCAF) specification calling for a new jet-powered interceptor/fighter aircraft suitable for long-distance patrol missions and all-weather operations. On 19 January 1950, the CF-100 Mark 1 prototype, 18101 , conducted its maiden flight , powered by

Along with Mark O'Neill, she says this accelerated Kim's war preparations. Chen Jian argues Mao never seriously challenged Kim's plans and Kim had every reason to inform Stalin that he had obtained Mao's support. Citing more recent scholarship, Zhao Suisheng contends Mao did not approve of Kim's war proposal and requested verification from Stalin, who did so via

On 19 January 1950, the CF-100 prototype flew its maiden flight with Gloster Aircraft Company Chief Test Pilot Squadron Leader Bill Waterton (on loan from Gloster, then also part of the Hawker Siddeley group) at the controls. The Mark 1 was powered by a pair of Rolls-Royce Avon RA 3 turbojet engines, each capable of generating

6111-429: The final years of the Second World War , officials in Canada had concluded both that the development of a self-sufficient indigenous military aviation industry would be of considerable national value and that the new field of jet propulsion held considerable promise. As early as July 1944, Canada had commenced work on its own turbojet engine programme, producing the experimental Avro Canada Chinook powerplant. During

By mid-1950, between 50,000 and 70,000 former PLA troops had entered North Korea, forming a significant part of the KPA's strength on the eve of the war's beginning. The combat veterans and equipment from China, the tanks, artillery, and aircraft supplied by the Soviets, and rigorous training increased North Korea's military superiority over

Insurgency reignited in the spring of 1949 when attacks by guerrillas in the mountainous regions (buttressed by army defectors and North Korean agents) increased. Insurgent activity peaked in late 1949 as the ROKA engaged so-called People's Guerrilla Units. Organized and armed by the North Korean government, and backed by 2,400 KPA commandos who had infiltrated through

Stalin made it clear Soviet forces would not openly engage in combat, to avoid a direct war with the US Kim met with Mao in May 1950 and differing historical interpretations of the meeting have been put forward. According to Barbara Barnouin and Yu Changgeng, Mao agreed to support Kim despite concerns of American intervention, as China desperately needed

The bridge was detonated while 4,000 refugees were crossing it, and hundreds were killed. Destroying the bridge trapped many ROK units north of the river. In spite of such desperate measures, Seoul fell that same day. Some South Korean National Assemblymen remained in Seoul when it fell, and 48 subsequently pledged allegiance to

The Mk 4B version was furnished with more powerful Orenda 11s. Five versions, or marks , were produced. The high-altitude Mk 5 was the final variant, production of which commenced during 1955. This model featured a 1.06 m (3 ft 6 in)-longer wingtip and enlarged tailplane, along with removal of

A decade later, after defeating Imperial Russia in the Russo-Japanese War , Japan made the Korean Empire its protectorate with the Eulsa Treaty in 1905, then annexed it with the Japan–Korea Treaty of 1910 . The Korean Empire fell, and Korea was directly ruled by Japan between 1910–45. Many Korean nationalists fled

6790-684: The insurgent war and border clashes. The first socialist uprising occurred without direct North Korean participation, though the guerrillas still professed support for the northern government. Beginning in April 1948 on Jeju Island , the campaign saw arrests and repression by the South Korean government in the fight against the South Korean Labor Party, resulting in 30,000 violent deaths, among them 14,373 civilians, of whom ~2,000 were killed by rebels and ~12,000 by ROK security forces. The Yeosu–Suncheon rebellion overlapped with it, as several thousand army defectors waving red flags massacred right-leaning families. This resulted in another brutal suppression by

6887-439: The invasion force, the North had 114 fighters, 78 bombers, 105 T-34-85 tanks, and some 30,000 soldiers stationed in reserve in North Korea. Although each navy consisted of only several small warships, the North and South Korean navies fought in the war as seaborne artillery for their armies. In contrast, the South Korean population was estimated at 20 million, but its army was unprepared and ill-equipped. As of 25 June 1950,

6984-511: The late 1940s and early 1950s, events such as the Korean War and Soviet atomic bomb project had contributed to the rising international tensions of what would become known as the Cold War ; the Canadian Government decided to respond by greatly increasing defense expenditure. The Royal Canadian Air Force (RCAF) was a major recipient of the expanded budget, reaching 46.6% of overall defense expenditure during FY 1951–1952, some of which

7081-755: The late 1950s, an advanced supersonic interceptor, CF-105 Arrow along with the sophisticated Orenda Iroquois engine, was under development by Avro Canada as an intended successor to the CF-100. However, during 1959, work on the CF-105 was terminated following a controversial decision by the Canadian government.

7178-401: The locally developed Orenda powerplant instead, the first of which flying during June 1951. As a result of delays encountered in the development of the Orenda, its selection unavoidably impacted the CF-100 programme's timetable as well. Dissatisfied with the pace of development, Cabinet Minister C. D. Howe informed Avro to suspend work on all other projects and focus its efforts on completing

7275-443: The loss and issues encountered, Avro Canada dismissed several members of the design team and established a special working group to rectify a major structural design error identified. To address the latter, a straightforward modification was developed that could be easily retrofitted into the pre-production aircraft. While both prototypes had been powered by Avon engines, the subsequent pre-production and production series aircraft used

7372-504: The machine guns. The proposed Mk 6 was to have mounted Sparrow II missiles and been powered by afterburning Orenda 11IR engines; this was intended to be adopted as an "interim" fighter prior to the introduction of the more advanced Avro Canada CF-105 Arrow , which was then under development. An advanced derivative of the CF-100 was the CF-103 , which was equipped with a swept wing and projected to be capable of transonic speeds; this

7469-429: The most heavily bombed countries in history, and virtually all of Korea's major cities were destroyed. No peace treaty has been signed, making the war a frozen conflict . In South Korea, the war is usually referred to as the "625 War" ( 6·25 전쟁 ; 六二五戰爭 ), the "625 Upheaval" ( 6·25 동란 ; 六二五動亂 ; yugio dongnan ), or simply "625", reflecting the date of its commencement on 25 June. In North Korea,

7566-541: The nationalist National Revolutionary Army and the communist People's Liberation Army (PLA) helped organize Korean refugees against the Japanese military, which had also occupied parts of China. The Nationalist-backed Koreans, led by Yi Pom-Sok , fought in the Burma campaign (1941-45). The communists, led by, among others, Kim Il Sung , fought the Japanese in Korea and Manchuria . At the Cairo Conference in 1943, China,

7663-509: The operation was conducted under the auspices of the UN. It has been sometimes referred to in the English-speaking world as "The Forgotten War" or "The Unknown War" because of the lack of public attention it received during and afterward, relative to the global scale of World War II, which preceded it, and the subsequent angst of the Vietnam War , which succeeded it. Imperial Japan diminished

7760-538: The pre-production aircraft were soon resolved. The first production version, designated Mk 3 , made its first flight during October 1952. The Mk 3 incorporated the APG-33 radar and was armed with eight .50 caliber Browning M3 machine guns. The Mk 3CT and Mk 3DT were again dual control versions supplied to operational training units. During mid-January 1955, a CF-100 arrived at Eglin AFB , Florida , for cold-weather tests in

7857-490: The report that contained the Haeju claim contained errors and outright falsehoods. KPA forces attacked all along the 38th parallel within an hour. The KPA had a combined arms force including tanks supported by heavy artillery. The ROK had no tanks, anti-tank weapons, or heavy artillery. The South Koreans committed their forces in a piecemeal fashion, and these were routed in a few days. On 27 June, Rhee evacuated Seoul with some of

7954-494: The southward movement by the KPA but assessed this as a "defensive measure" and concluded an invasion was "unlikely". On 23 June UN observers inspected the border and did not detect that war was imminent. Chinese involvement was extensive from the beginning, building on previous collaboration between the Chinese and Korean communists during the Chinese Civil War. Throughout 1949 and 1950, the Soviets continued arming North Korea. After

8051-479: The term " Chosŏn War" ( Chinese : 朝鮮戰爭 ; pinyin : Cháoxiǎn Zhànzhēng ) is sometimes used unofficially. The term " Hán (Korean) War" ( Chinese : 韓戰 ; pinyin : Hán Zhàn ) is most used in Taiwan (Republic of China), Hong Kong and Macau . In the US, the war was initially described by President Harry S. Truman as a " police action " as the US never formally declared war on its opponents, and

8148-502: The type was flown by several United States Air Force (USAF) crews. The operational suitability tests, dubbed Project Banana Belt , were carried out by the 3241st Test Group (Interceptor) of the APGC's Air Force Operational Test Center , in conjunction with a project team belonging to the RCAF. During September 1950, the RCAF placed an initial production order for 124 Mk 3 aircraft, the first of which entering service in 1953. This model

8245-557: The war is officially referred to as the Fatherland Liberation War ( Choguk haebang chŏnjaeng ) or the " Chosŏn [Korean] War" ( 조선전쟁 ; Chosŏn chŏnjaeng ). In mainland China, the segment of the war after the intervention of the People's Volunteer Army is commonly and officially known as the "Resisting America and Assisting Korea War" ( Chinese : 抗美援朝战争 ; pinyin : Kàngměi Yuáncháo Zhànzhēng ), although

8342-547: Was administered by a US–Soviet Union Joint Commission , as agreed at the Moscow Conference , to grant independence after a five-year trusteeship. Waiting five years for independence was unpopular among Koreans, and riots broke out. To contain them, the USAMGIK banned strikes on 8 December and outlawed the PRK Revolutionary Government and People's Committees on 12 December. Following further civilian unrest,

8439-414: Was almost entirely trained and focused on counterinsurgency, rather than conventional warfare. They were equipped and advised by a force of a few hundred American officers, who were successful in helping the ROKA to subdue guerrillas and hold its own against North Korean military (Korean People's Army, KPA) forces along the 38th parallel. Approximately 8,000 South Korean soldiers and police officers died in

8536-532: Was an armed conflict on the Korean Peninsula fought between North Korea (Democratic People's Republic of Korea; DPRK) and South Korea (Republic of Korea; ROK) and their allies. North Korea was supported by the People's Republic of China and the Soviet Union , while South Korea was supported by the United Nations Command (UNC) led by the United States . The conflict was thus the first major proxy war of

8633-404: Was armed with eight .50 caliber machine guns. The definitive rocket-armed Mk 4A was based on the prototype Mk 4 (a modified Mk 3), which first flew on 11 October 1952. The nose housed the much larger APG-40 radar , while the wings were equipped with wingtip pods, each containing up to 29 Mk 4/Mk 40 "Mighty Mouse" folding-fin aerial rocket , to be used in addition to

8730-467: Was built in mock-up form during 1951, but was considered obsolete even before the CF-100's demonstrated ability to exceed the speed of sound in a dive. On 18 December 1952, Squadron Leader Janusz Żurakowski , the Avro company chief development test pilot, took the CF-100 Mk 4 prototype to Mach 1.0 in a dive from 9,100 m (30,000 ft), becoming the first straight-winged jet aircraft to achieve controlled supersonic flight. Amongst RCAF pilots,

8827-493: Was no US policy dealing with South Korea directly as a national interest, its proximity to Japan increased its importance. Said Kim: "The recognition that the security of Japan required a non-hostile Korea led directly to President Truman's decision to intervene ... The essential point ... is that the American response to the North Korean attack stemmed from considerations of U.S. policy toward Japan." Another consideration

8924-422: Was no existing aircraft that could satisfy the specification, nor was there any suitable aircraft already in development elsewhere, thus it was deemed necessary for Canada to develop such a fighter itself. On 3 November 1945, an agreement was struck to develop a prototype jet-powered fighter on behalf of the RCAF; on 13 October 1946, the issuing of government contracts to aircraft manufacturer Avro Canada enabled

9021-401: Was not included in the strategic Asian Defense Perimeter outlined by United States Secretary of State Dean Acheson . Military strategists were more concerned with the security of Europe against the Soviet Union than that of East Asia . The administration was worried a war in Korea could quickly escalate without American intervention. Diplomat John Foster Dulles stated: "To sit by while Korea

9118-770: Was not the case. Rather, the soldiers were indigenous to China, as part of China's longstanding ethnic Korean community, and were recruited to the PLA in the same way as any other Chinese citizen. According to the first official census in 1949, the population of North Korea numbered 9,620,000, and by mid-1950, North Korean forces numbered between 150,000 and 200,000 troops, organized into 10 infantry divisions, one tank division, and one air force division, with 210 fighter planes and 280 tanks, who captured scheduled objectives and territory, among them Kaesong, Chuncheon , Uijeongbu , and Ongjin. Their forces included 274 T-34-85 tanks, 200 artillery pieces, 110 attack bombers, 150 Yak fighter planes, and 35 reconnaissance aircraft. In addition to

9215-498: Was reduced to a single man over the course of engagements by the ROKA 8th Division . The second was annihilated by a two-battalion hammer-and-anvil maneuver by units of the ROKA 6th Division , resulting in a toll of 584 KPA guerrillas (480 killed, 104 captured) and 69 ROKA troops killed, plus 184 wounded. By the spring of 1950, guerrilla activity had mostly subsided; the border, too, was calm. By 1949, South Korean and US military actions had reduced indigenous communist guerrillas in

9312-632: Was so great that the USAF was willing to consider two foreign designs: the CF-100 and the English Electric Canberra . Following an evaluation, the CF-100 was rejected due to its insufficient range and payload capabilities; the rival English Electric design was selected and developed into the Martin B-57 Canberra . At its peak, the CF-100 served with nine RCAF squadrons in the mid-1950s. Four of these squadrons were deployed to Europe under

9409-644: Was the Soviet reaction if the US intervened. The Truman administration was fearful a Korean war was a diversionary assault that would escalate to a general war in Europe once the US committed in Korea. At the same time, "[t]here was no suggestion from anyone that the United Nations or the United States could back away from [the conflict]". Yugoslavia —a possible Soviet target because of the Tito-Stalin split —was vital to
