74-558: Over 4,000 Orendas of various marks were delivered during the 1950s. The Orenda design started in the summer of 1946 when the Royal Canadian Air Force (RCAF) placed an order with Avro Canada for a new night/all-weather fighter . To power the design, Avro decided to build their own engines. Avro had recently purchased Turbo Research , a former crown corporation set up in Leaside , Toronto , to develop jet engines. Turbo Research

Captains, lieutenants and second lieutenants are the junior level leaders in RCAF squadrons and headquarters. On 1 April 2015, the rank structure and insignia changed. The rank of private was replaced with that of aviator, represented with

296-616: A new environmental command called simply Air Command ( AIRCOM ; French: Commandement aérien ). Air Command reverted to its historic name of "Royal Canadian Air Force" in August 2011. The Royal Canadian Air Force has served in the Second World War , the Korean War , the Persian Gulf War , as well as several United Nations peacekeeping missions and NATO operations. As a NATO member,

370-414: A propeller for the rank insignia. The previously used term " leading aircraftman " was considered not to be gender neutral. The rank insignia were also changed: enlisted ranks were changed from gold to pearl-grey (silver) and officers rank braid was changed from gold to pearl-grey on black, similar to the pattern used before unification of Canada's armed forces in 1968. A revival of the former rank titles of

444-574: A public company. Nevertheless, NAA continued with new designs, including the T-28 Trojan trainer and attack aircraft, the F-82 Twin Mustang fighter, B-45 Tornado jet bomber, the FJ Fury fighter, AJ Savage , the revolutionary XB-70 Valkyrie Mach-3 strategic bomber , Shrike Commander , and T-39 Sabreliner business jet. The Columbus, Ohio division of North American Aviation was instrumental in

518-553: Is now part of Boeing . On December 6, 1928, Clement Melville Keys founded North American as a holding company that bought and sold interests in various airlines and aviation-related companies. However, the Air Mail Act of 1934 forced the breakup of such holding companies. North American became a manufacturing company, run by James H. "Dutch" Kindelberger , who had been recruited from Douglas Aircraft Company . NAA did retain ownership of Eastern Air Lines until 1938. In 1933,

As of 2020, the Royal Canadian Air Force consists of 12,074 Regular Force and 1,969 Primary Reserve personnel, supported by 1,518 civilians, and operates 258 manned aircraft and nine unmanned aerial vehicles . Lieutenant-General Eric Kenny

740-624: The GA-15 observation plane and the GA-16 trainer, followed by the O-47 and BT-9 , also called the GA-16. The BC-1 of 1937 was North American's first combat aircraft; it was based on the GA-16. In 1940, like other manufacturers, North American started gearing up for war, opening factories in Columbus, Ohio , Dallas, Texas , and Kansas City, Kansas . North American ranked eleventh among United States corporations in

814-700: The General Motors Corporation purchased a controlling interest in NAA, and merged it with the General Aviation Manufacturing Corporation , but retained the name North American Aviation. Kindelberger moved the company's operations from Dundalk, Maryland to Los Angeles, California , which allowed flying year-round, and decided to focus on training aircraft, on the theory that it would be easier than trying to compete with established companies on larger projects. NAA's first planes were

888-610: The North American Aerospace Defense Command (NORAD). The RCAF also provides all primary air resources to and is responsible for the National Search and Rescue Program . The RCAF traces its history to the Canadian Air Force , which was formed in 1920. The Canadian Air Force was granted royal sanction in 1924 by King George V to form the Royal Canadian Air Force. In 1968, the RCAF was amalgamated with

962-721: The P-47 Thunderbolts of the Air National Guard that were sent to investigate. In one incident at an airshow, all four engines were turned off by mistake, but the Orenda's quick start time allowed them to save the day. The aircraft ran up 500 hours by July 1954, when this portion of flight testing ended; it was destroyed in a hangar fire on 24 July 1956. The Orenda 2 was the first production model, passing its qualification tests in February 1952. This version showed additional cracking in

1036-503: The Royal Canadian Navy and the Canadian Army , as part of the unification of the Canadian Forces . Air units were split between several different commands: Air Defence Command (ADC; interceptors), Air Transport Command (ATC; airlift, search and rescue), Mobile Command (tactical fighters, helicopters), Maritime Command (anti-submarine warfare, maritime patrol), as well as Training Command (TC). In 1975, some commands (ADC, ATC, TC) were dissolved, and all air units were placed under

1110-597: The S-II second stage of the Saturn V . The fatal Apollo 1 fire in January 1967 was initially blamed on the company in the press, although a Congressional Hearing later ruled otherwise. In September, it merged with Rockwell-Standard, and the merged company became known as North American Rockwell . During this period the company continued its involvement with the Apollo program , building

1184-693: The SAGE radar stations within NORAD; Air Transport Command: provided strategic airlift for the NATO and UN peacekeeping missions; and Training Command . Aviation assets of the Royal Canadian Navy were combined with the RCAF Canadair CP-107 Argus long-range patrol aircraft under Maritime Command.

Through a series of mergers and sales, North American Aviation became part of North American Rockwell , which later became Rockwell International , and

1332-571: The US Navy and US Marine Corps for four decades. The Buckeye's name would be an acknowledgment to the state tree of Ohio , as well as the mascot of Ohio State University . The North American F-86 Sabre started out as a redesigned Fury and achieved fame shooting down MiGs in the Korean War . Over 9,000 F-86s were produced. Its successor, the North American F-100 Super Sabre , was also popular. Some 6,656 F-86s were produced in

1406-463: The Waconda . The Orenda was fairly conventional in layout, built in three main parts; compressor, combustion area, and turbine/exhaust. At the front was the compressor section, containing the ten-stage compressor housed in a tapering magnesium alloy shell. The shell was machined with grooves that held the stators. At the front of the compressor was an intake fairing with a prominent "nose cone" containing

1480-511: The X-15 , a rocket-powered aircraft that first flew in 1959. In 1959, North American built the first of several Little Joe boosters used to test the launch escape system for the Project Mercury spacecraft . In 1960, the new CEO Lee Atwood decided to focus on the space program , and the company became the prime contractor for the Apollo command and service module , a larger Little Joe II rocket to test Apollo's launch escape system, and

1554-546: The 2000s, AIRCOM was heavily involved in the Afghanistan War , transporting troops and assets to Kandahar. Later in the decade-long war, AIRCOM set up a purpose-specific air wing, Joint Task Force Afghanistan Air Wing, equipped with several CH-146 Griffon and CH-147 Chinook helicopters, CC-130 Hercules, CU-161 Sperwer and leased CU-170 Heron UAVs in support of the Canadian Forces and ISAF mission. The wing stood down on 18 August 2011. From 18 March to 1 November 2011,

The 32¢ stamps are perforated 12 x 12.5 and were printed by Ashton-Potter Limited. North American Aviation North American Aviation ( NAA ) was a major American aerospace manufacturer that designed and built several notable aircraft and spacecraft. Its products included

1850-636: The Columbus plant grew from 1,600 in 1950 to 18,000 in 1952. The cancellation of the F-107 and F-108 programs in the late 1950s, as well as the cancellation of the Navaho intercontinental cruise missile program, was a blow to North American from which it never fully recovered. Atomics International was a division of North American Aviation which began as the Atomic Energy Research Department at

1924-778: The Command and Service modules for all eleven missions. Within two years the new company also was studying concepts for the Space Shuttle , and won the orbiter contract in 1972. In 1973, the company changed its name again to Rockwell International and named its aircraft division North American Aircraft Operations. Rockwell International's defense and space divisions (including the North American Aviation divisions Autonetics and Rocketdyne) were sold to Boeing in December 1996. Initially called Boeing North American, these groups were integrated with Boeing's Defense division. Rocketdyne

1998-554: The Downey plant in 1948. In 1955, the department was renamed Atomics International and engaged principally in the early development of nuclear technology and nuclear reactors for both commercial and government applications. Atomics International was responsible for a number of accomplishments relating to nuclear energy: design, construction and operation of the first nuclear reactor in California (a small aqueous homogeneous reactor located at

2072-682: The F-35A. Following the 2015 Federal Election the Liberal Party , whose campaign had included a pledge to cancel the F-35 procurement, formed a new government and commenced an open competition to replace the existing CF-18 Hornet . On 28 March 2022, the Government of Canada announced that the competition had placed the F-35A first and planned to buy 88 of them. Under procurement rules, the government entered into negotiations with Lockheed Martin. On 9 January 2023,

As overall interest in nuclear power declined, Atomics International transitioned to non-nuclear energy-related projects such as coal gasification and gradually ceased designing and testing nuclear reactors. Atomics International

2220-545: The P-51 into what many consider to be the best American fighter of the war. Labor troubles became a grave issue in 1941. During the 22 months from August 1939 to June 1941 Stalin and Hitler supported each other as war raged in Europe. In the U.S., local union officials opposed American aid to Britain's war against Germany. They called strikes in war industries that were supplying Lend Lease to Britain. The United Auto Workers (UAW) won

2294-516: The RCAF contract. Winnett Boyd started detailed design in autumn 1946, and a formal contract was received in April 1947. The only major change was the addition of a tenth compressor stage of stainless steel, and changing the third stage from aluminum to steel as well. The design work was completed on 15 January 1948, just prior to the first run of the Chinook on 17 March 1948. During the design Joseph Lucas of

2368-436: The RCAF did not occur, however, as such an extensive change was considered "too complicated and confusing". Instead, the current rank titles were retained (with the exception of aviator). The Royal Flying Corps , considered to be a predecessor of the RCAF, used rank titles similar to the existing rank titles of the RCAF. The badge of the Royal Canadian Air Force consists of: Roundels used from 1920 until 1945 were usually

2442-557: The RCAF established No. 1 Air Division RCAF consisting of four wings with three fighter squadrons each, based in France and West Germany. In 1950, the RCAF became involved with the transport of troops and supplies to the Korean War ; however, it did not provide RCAF combat units. Members of the RCAF served in USAF units as exchange officers and several flew in combat. Both auxiliary and regular air defence squadrons were run by Air Defence Command . At

2516-531: The RCAF was engaged in Operation Mobile , Canada's contribution to Operation Unified Protector in Libya. Seven CF-18 Hornet fighter aircraft and several other aircraft served under Task Force Libeccio as part of the military intervention. On 16 August 2011, the Government of Canada announced that the name "Air Command" was being changed to the air force's original historic name: Royal Canadian Air Force (along with

The resulting Sabre was both lighter and more powerful than its J47 powered counterparts, and went on to set a number of air speed records. Most notable among these was Jacqueline Cochran 's supersonic flight in the sole Sabre 3, which Canadair loaned to her for

2664-532: The UK was contracted to help with the combustion design, which led to a slight delay as they recommended using a longer combustion chamber than originally designed. The resulting TR-5 was named "Orenda", an Iroquois word meaning "Tribal Soul on the Right Path". Given the experience of the Chinook, and the fact that the two designs were similar in many ways, progress on the Orenda was rapid. Parts started arriving in 1948, and

2738-512: The USSR on June 22, the Communist activists suddenly became the strongest supporters of war production; they crushed wildcat strikes. Post-war, North American's employment dropped from a high of 91,000 to 5,000 in 1946. On V-J Day , North American had orders from the U.S. government for 8,000 aircraft. A few months later, that had dropped to 24. Two years later in 1948, General Motors divested NAA as

2812-488: The United States, the most produced postwar military aircraft in the West, as well as another 2,500 elsewhere. To accommodate its Sabre production, North American opened facilities in a former Curtiss-Wright plant in Columbus, Ohio . It also moved into a former Consolidated-Vultee Aircraft plant at Downey, California , and in 1948, built a new plant at Downey. By the end of 1952, North American sales topped $ 315 million. Employment at

2886-546: The air force began to rebuild. During the Second World War , the RCAF was a major contributor to the British Commonwealth Air Training Plan and was involved in operations in the United Kingdom , Europe, the north Atlantic, North Africa , southern Asia, and with home defence. Eight thousand, eight hundred and sixty-four Americans came north to volunteer for the RCAF and over 850 died in action. By

2960-522: The change of name of Maritime Command to Royal Canadian Navy and Land Force Command to Canadian Army). The change was made to better reflect Canada's military heritage and align Canada with other key Commonwealth countries whose military units use the royal designation. The RCAF adopted a new badge in 2013, which is similar to the pre-unification RCAF badge (although placed in the modern frame used for command badges). The Latin motto of Air Command – Sic itur ad astra  – which

3108-727: The early 1990s, Canada provided a detachment of CF-18 Hornets for the air defence mission in Operation Desert Shield . The force performed combat air patrols over operations in Kuwait and Iraq, undertook a number of air-to-ground bombing missions, and, on one occasion, attacked an Iraqi patrol boat in the Persian Gulf . In the late 1990s, Air Command's CF-18 Hornets took part in the Operation Allied Force in Yugoslavia , and in

3182-430: The effort. Canadair built 1,815 Sabres in total, 937 of these equipped with Orendas. Several examples, notably one at Boeing , serving into the 1970s. The engine was so successful that the Gas Turbine Division was renamed Orenda Engines when Hawker Siddeley reorganized their Canadian operations in 1955. By 1953 the Orenda was planned to have been joined by an engine in the 10,000 lbf (44 kN) thrust range,

UAW negotiators demanded the starting pay be raised from 50 cents an hour to 75 cents, plus a 10 cents raise for the 11,000 current employees. The national union had made a no-strike pledge but suddenly a wildcat strike by the local on June 5 closed

3330-427: The end of the war, the RCAF had become the fourth largest Allied air force. During World War II the RCAF was headquartered at a six-storey office building at 20-23 Lincoln's Inn Fields (built 1937), London. A commemorative plaque can be found on the outside of the building. After the war, the RCAF reduced its strength. Because of the rising Soviet threat to the security of Europe, Canada joined NATO in 1949, and

3404-501: The exclusive development and production of the A-5 Vigilante , an advanced high speed attack aircraft that saw significant use as a naval reconnaissance aircraft during the Vietnam War , the OV-10 Bronco , the first aircraft specifically designed for forward air control (FAC), and counter-insurgency (COIN) duties, and the T-2 Buckeye Naval trainer, which would serve from the late 1950s until 2008 and be flown in training by virtually every Naval Aviator and Naval Flight Officer in

3478-451: The first engine was completed and run for the first time on 8 February 1949. Avro was so confident of the design that they invited high-ranking officials from the RCAF and Canadian government to witness this very first test, which went off without a hitch after fixing a minor electrical problem. Within two months the engine had already passed 100 hours of running time, and on 10 May had reached its design thrust of 6,000 lbf (27 kN). At

3552-426: The first nine stages, and a steel disk bolted onto the end carrying the tenth. The central casing held the power shaft and was made from magnesium alloy. Around it were the six flame cans . The turbine was made of solid Inconel blades attached to an austenitic steel hub. The blades were air cooled by bleeding off compressed air from the fifth compressor stage and piping it to the turbine face, the six pipes lying between

3626-434: The flame cans. The exhaust section consisted of welded steel sheeting.

3700-451: The force maintained a presence in Europe during the second half of the 20th century. The Canadian Air Force (CAF) was established in 1920 as the successor to a short-lived two-squadron Canadian Air Force that was formed during the First World War in Europe. Wing Commander John Scott Williams was tasked in 1921 with organizing the CAF, handing command over later the same year to Air Marshal Lindsay Gordon . The new Canadian Air Force

3774-421: The front main bearing. Four guide vanes held the cone in place, with two power takeoff shafts running inside two of them to power the top- and bottom-mounted accessories section (fuel pumps, oil pumps). The nose cone also held the electric starter motor, which acted as a generator once the engine was up and running. The engines used on the CF-100 also contained a uniquely Canadian invention, two prominent winglets at

3848-513: The government of Canada officially ordered 88 F-35As. On 19 December 2023 the Government of Canada announced that a contract was signed for 11 MQ-9B drones, 219 Hellfire missiles , and 12 Mk82 500-pound bombs in a deal worth $ 2.49 billion CAD. The drones are expected to be first delivered in 2028 with full operation expected in 2033. The drones are to be stationed in 14 Wing Greenwood , N.S. with 55 personnel and with 25 personnel at 19 Wing Comox , B.C. and in Ottawa with 160 staff to control

3922-417: The more powerful compressor. The 11 would be the primary production version for the CF-100, powering the Mk.4A and all future versions, with over 1,000 engines produced. While work on the CF-100 continued the RCAF also started looking at a new day fighter , eventually selecting the Sabre. A single Sabre 3 was built with the Orenda 4 engine, with performance similar to the US models. Production then turned to

3996-476: The ninth stage, and had to be strengthened like the earlier model. Even before being qualified, the engine had been fitted to the Avro CF-100 and flown on 20 June 1952, with a squadron of pre-production Mk.2 aircraft entering RCAF service on 17 October. The Orenda 3 was similar, but had a number of modifications to allow it to be mounted in the Sabre in place of the J47. One example was produced and sent to North American Aviation . The first real production model

4070-401: The past decade. Transport aircraft have been leased as required. Despite RCAF marking all aircraft have civilian registration numbers. The Canadian CF-35 is a proposed variant that would differ from the F-35A through the addition of a drogue parachute and may include an F-35B/C-style refuelling probe. In 2012, it was revealed that the CF-35 would employ the same boom refuelling system as

4144-472: The plant that produced a fourth of the fighters. The UAW national leader Richard Frankensteen flew in but was unable to get the workers to return. So Washington intervened. With the approval of national CIO leadership, President Franklin Roosevelt on June 8 sent in the California national guard to reopen the plant with bayonets. Strikers were told to return immediately or be drafted into the US Army. They sullenly complied. However, when Germany suddenly invaded

Flight testing started with a converted Avro Lancaster , FM209 , one of the many Mk.10's built at the Victory Aircraft (now Avro) plants during the war. The two outboard Merlin engines were replaced with the Orendas, and the new aircraft took to the sky on 10 July. Avro test pilots flight tested the aircraft across Lake Ontario to the Buffalo, New York area, where they were able to easily outperform

4292-485: The same as Royal Air Force roundels although not all variations were used and colours were matched to locally available paints. On 5 July 1940, the RCAF was authorized to introduce the maple leaf into the roundel in place of the red centre. However, a large amount of RCAF planes still continued to use the RAF roundel until 1945 since their aircraft, including those built in Canada all came through RAF channels. On 9 November 1984, Canada Post issued "Air Force" as part of

4366-491: The same time, the Pinetree Line , the Mid-Canada Line and the DEW Line radar stations, largely operated by the RCAF, were built across Canada because of the growing Soviet nuclear threat. In 1957, Canada and the United States created the joint North American Air Defense Command (NORAD). Coastal defence and peacekeeping also became priorities during the 1950s and 1960s. In 1968, the Royal Canadian Navy , Royal Canadian Air Force and Canadian Army were amalgamated to form

4588-508: The value of wartime production contracts. North American's follow-on to the BT-9 was the T-6 Texan trainer, of which 17,000 were built, making it the most widely used trainer ever. The twin-engine B-25 Mitchell bomber achieved fame in the Doolittle Raid and was used in all combat theaters of operation. The P-51 Mustang was initially produced for Britain as an alternative to the Curtiss P-40 Warhawk , which North American had declined to produce under licence. The derivative A-36 Mustang

Many CAF members also worked with the Air Board's Civil Operations Branch on operations that included forestry , surveying and anti-smuggling patrols. In 1923, the CAF became responsible for all flying operations in Canada, including civil aviation. In 1924, the Canadian Air Force,

4810-439: Was carried out with a set of metal rings in the intake to avoid ingesting foreign objects. After repairing the damage the engine returned to testing, now joined by two further examples of the Orenda 1 . Together they passed a total of 2,000 hours by 10 February 1950. By this point a problem with fatigue cracks in the seventh and eighth stages had become apparent, which required them to be redesigned and made much thicker. This solved

4884-435: Was developed as a ground attack aircraft and dive bomber. This was done, in part, to keep the airframe in production as the US Army Air Corps had not yet decided to purchase the type as a fighter. A suggestion by the RAF that North American switch the P-51's powerplant from its original Allison engine to the Rolls-Royce Merlin engine may have been one of the most significant events in World War II aviation, as it transformed

5254-438: Was in the midst of designing their first engine, the 3,000 lbf (13 kN) TR.4 Chinook , which could easily be scaled up for the new fighter design. It was decided to continue working on the Chinook to gain experience even though they had no intention of producing it. As work on the Chinook continued, Avro's newly christened Gas Turbine Division started work on the larger 6,000 lbf (27 kN) thrust design needed for

This division furnished engines for the Redstone , Jupiter , Thor , Delta , and Atlas missiles, and for NASA 's Saturn family of launch vehicles . North American designed and built the airframe for

5402-514: Was the Orenda 8 , which was the powerplant of the CF-100 Mk.3. This model was first flown in September 1952 and entered service in 1953. This was soon followed by the Orenda 9 powered Mk.4 that flew on 11 October 1952, and then by the rocket-armed Mk.4A with the 7,400 lbf (33 kN) Orenda 11 . The Orenda 11 demanded higher airflow through the engine, and featured a second turbine stage to power

5476-588: Was the motto of the Canadian Air Force when first formed after the First World War (before it became the Royal Canadian Air Force in 1924) was retained. Though traditional insignia for the RCAF was restored in 2015, there has been no restoration of the traditional uniforms or rank structure of the historical service (apart from a rank of "aviator", which replaced that of "private" in 2015).
