Foundation and relocation

The company was established in 1946 at the Novosibirsk Aircraft Production Association as the top-secret Soviet Research and Design Bureau No. 153 (OKB-153). It was headed by Oleg Antonov and specialised in turboprop military transport aircraft. The task was to create an agricultural aircraft CX-1 (An-2), the first flight of which occurred on 31 August 1947. The An-2 biplane was a major achievement of this period, with hundreds of these aircraft still operating as of 2013.^[6] In addition to this biplane and its modifications, a small series of gliders A-9 and A-10 were created and built in the pilot production in Novosibirsk. In 1952, the Bureau was relocated to Kyiv, a city with a rich aviation history and an aircraft-manufacturing infrastructure restored after the destruction caused by World War II.

First serial aircraft and expansion

The 1957 introduction of the An-10/An-12 family of mid-range turboprop aeroplanes began the successful production of thousands of these aircraft. Their use for both heavy combat and civilian purposes around the globe continues to the present; the An-10/An-12 were used most notably in the Vietnam War, the Soviet–Afghan War and the Chernobyl disaster relief megaoperation.

In 1959, the bureau began construction of the separate Flight Testing and Improvement Base in suburban Hostomel (now the Antonov Airport).

In 1965, the Antonov An-22 heavy military transport entered serial production to supplement the An-12 in major military and humanitarian airlifts by the Soviet Union. The model became the first Soviet wide-body aircraft, and it remains the world's largest turboprop-powered aircraft. Antonov designed and presented a nuclear-powered version of the An-22. It was never flight tested.

In 1966, after the major expansion in the Sviatoshyn neighbourhood of the city, the company was renamed to another disguise name: "Kyiv Mechanical Plant". Two independent aircraft production and repair facilities, under engineering supervision of the Antonov Bureau, also appeared in Kyiv during this period.

Prominence and Antonov's retirement

In the 1970s and early 1980s, the company established itself as the Soviet Union's main designer of military transport aircraft with dozens of new modifications in development and production. After Oleg Antonov's death in 1984, the company was officially renamed as the Research and Design Bureau named after O.K. Antonov (Russian: Опытно-конструкторское бюро имени О.К. Антонова) while continuing the use of "Kyiv Mechanical Plant" alias for some purposes.

Late Soviet-era: superlarge projects and first commercialisation

An-225 was the largest operative aircraft in the world.

In the late 1980s, the Antonov Bureau achieved global prominence after the introduction of its extra large aeroplanes. The An-124 "Ruslan" (1982) became the Soviet Union's mass-produced strategic airlifter under the leadership of Chief Designer Viktor Tolmachev. The Bureau enlarged the "Ruslan" design even more for the Soviet spaceplane programme logistics, creating the An-225 "Mriya" in 1985. "Mriya" was the world's largest and heaviest aeroplane.^[7]

The end of the Cold War and perestroika allowed the Antonov company's first step to commercialisation and foreign expansion. In 1989, the Antonov Airlines subsidiary was created for its own aircraft maintenance and cargo projects.

Expansion to free market

Since independence, Antonov has certified and marketed both Soviet-era and newly developed models for sale in new markets outside of the former soviet-sphere of influence. New models introduced to serial production and delivered to customers include the Antonov An-140, Antonov An-148 and Antonov An-158 regional airliners.

Among several modernisation projects, Antonov received orders for upgrading "hundreds" of its legendary An-2 utility planes still in operation in Azerbaijan, Cuba and Russia to the An-2-100 upgrade version.^[6]

In 2014, following the annexation of the Crimea by Russia, Ukraine cancelled contracts with Russia, leading to a significant income reduction in Ukraine's defense and aviation industries.^[8] However Ukraine has been slowly recovering the deficit from breaking ties with Russia by entering new markets such as the Persian Gulf region^[9][10] and expanding its presence in old ones such as India.^{[11][12][13][14][15]}

In July 2018, Antonov was able to secure a deal with Boeing in order to procure airplane parts which were no longer available due to breakdown of relations with Russia.^[16]

Production facilities' consolidation

During the Soviet period, not all Antonov-designed aircraft were manufactured by the company itself. This was a result of Soviet industrial strategy that split military production between different regions of the Soviet Union to minimise potential war loss risks. As a result, Antonov aeroplanes were often assembled by the specialist contract manufacturers.

In 2009, the once-independent "Aviant" aeroplane-assembling plant in Kyiv became part of Antonov, facilitating a full serial manufacturing cycle of the company. However, the old tradition of co-manufacturing with contractors is continued, both with Soviet-time partners and with new licensees like Iran's Iran Aircraft Manufacturing Industrial Company.^[17]

In 2014, the Antonov produced and delivered only two An-158 airplanes.^[18] This trend continued onto 2015, producing one An-148 and one An-158.^[19] Since 2016, no aircraft have been produced or delivered to clients.^[20]

In June 2016, Ukraine's major state-owned arms manufacturer Ukroboronprom announced the creation of the Ukrainian Aircraft Corporation within its structure, thereby combining all aircraft manufacturing enterprises, including the assets of Antonov into a single cluster, according to Ukroboronprom's press service.^[21]

On 19 July 2017, the Ukrainian government approved the liquidation of Antonov's assets.^[22][23] The State Concern "Antonov" (a business group, created in 2005 from the merger of several legally independent companies into a single economic entity under unified management) will be liquidated as a residual corporate entity. Antonov State Company, Kharkiv State Aviation Manufacturing Enterprise and Plant No.410 of Civil Aviation were transferred under the management of another state-owned concern Ukroboronprom in 2015. Antonov State Company continues to function as an enterprise.^[24]

On 31 March 2017, the first prototype of a new multifunctional cargo plane An-132 – a demonstration plane An-132D – took to the air from the runway of Sviatoshyn airfield. The An-132 development program had been implemented in the framework of a contract with a customer from Saudi Arabia.

On 24 February 2022, at the beginning of Russia's full-scale invasion in Ukraine, the first attacks were launched at Kyiv-Antonov-2 airfield, the site of Antonov's test flights and home base of the planes of Antonov Airlines. The planes An-26, An-74 and administrative premises were destroyed. The planes Аn-225 Mriya, Аn-12, Аn-22, Аn-28, Аn-132D and Аn-124-100-150, the hangars and other infrastructure were severely damaged.

The Security Service of Ukraine established that the former director general of Antonov Company Serhiy Bychkov had not provided access to the site for the National Guard in January and February 2022 and thus obstructed preparations for defence.^[25]

The investigators consider that Bychkov's negligence is the direct cause of the loss of Mriya, because the plane could have been sent to Germany long before February 24. In March 2023, Serhiy Bychkov was arrested, in April he faced formal suspicion in connection with the loss of An-225 Mriya and damages to Antonov amounting to ₴8.4 million.^[26][27][28]
