ITA / Instituto Aerotecnico
https://es.wikipedia.org/wiki/F%C3%A1brica_Argentina_de_Aviones

Activity: Airplane Manufacturing
Project: 1943
Completed: 1943

1943 President Ramirez reorganized the FMA into the Aerotechnical Institute, pouring more resources into it and focusing on developing the country’s aeronautical industry by centralizing all the companies related to the activity and including civilian companies in the process. New designs are made, specifically the FMA 21, a wholly metallic training plane. Though completed, it was never mass manufactured due to lack of materials.

1944-1955 The Institute keeps developing new models and techniques. After the end of WW2 specialists are hired and brought to work at Argentina. Among them are Kurk W. Tank, director of the Focke Wulf Flugzeugbau of Bremen, Professor Thalau, director of the Fieseler Aircraft Factory, along with their teams. Many other specialists would also flock to Argentina during these years. In the year 1947, the Pulqui I, designed by Emile Dewoitine becomes the first reaction plane made in South America. The same year, Kurt Tank starts working on a severely improved version that would become the Pulqui II. This plane first took flight in 1950. The plane could fly at 960km/2, had a 2.000km range and its maximum height was tapped at 15.000m. On 1953 Reimar Horten introduced the I.Ae.37 Delta Wing, a supersonic dual reactor fighter plane.

Altos Hornos Zapla S.A.

Activity: Mining, Foresting, Metallurgy
Projected: 1939
Completed: 1945

1939 A hunter interested in geology and minerals gathers soil samples from the Zapla forest in Jujuy and sends them to Buenos Aires for analysis. The place is found to have valuable deposits of hematite. The composition of the mineral is found to be very similar to the German hematite seen on Turingia. The percentage of iron on soil is low (40%) but the government decides to mine it anyway. While not particularly cost effective, it advances the country’s metallurgic industry.

1943 A power plant is established on the site. The DGFM oversees the project.

1945 The site begins operations. It attracts specialist from surrounding provinces and from Bolivia, raising Jujuy’s population considerably.

https://es.wikipedia.org/wiki/Bunge_%26_Born

Activity: Food Processing, international trade of grains and oilseeds.
Subsidiary of: Bunge & Born (Dutch Capitals)
Established: 1902

1902 The Bunge & Born company reinforces its industrialization efforts on Argentina by building a flour mill on Puerto Madero, Buenos Aires. The company monopolizes the market by buying wheat at high prices and then selling flour at low ones, thus ruining small and medium competitors. At the same time, in order to bypass custom taxes, the company expands to Uruguay and Brazil.

1910 By this time, the company is specialized in trading and exporting grains. It’s already one of the great players in the agricultural commodities market of the world. Together with Dreyfus & Weil they control 80% of the world’s market.

1914 The outbreak of the Great War gives the company a warning about the risks of being so specialized. The stagnation of the agricultural activity and deceleration of world trade advised against it.

1920 The company expands its activities to cotton, sunflowers, peanuts, soy, rice, yerba mate and vegetable oils. This allows it to enter the consumer goods market through several new subsidiaries.

1924 La Fabril S.A, specialized in cotton activities, is built.

1926 A vegetable oil factory is established on Resistencia, Chaco. GRAFA S.A. is built on Villa Pueyrredon (Buenos Aires), it makes bedsheets, blankets and covers at first at first, expanding to tablecloths, clothes and towels later. The Bunge & Born Holding opens its corporate building on Buenos Aires.

1926-1930 Albor S.A. (later Alba S.A.) is established. It’s the first paint factory of South America. During this time Bunge & Born expands in Brazil, creating the SANBRA (cotton concern) and SAMRIG (mills). It also holds actions on the SANFLU Holding. After the death of Eduoard Bugne on 1927, Alfredo Hirsch takes over the holding in Buenos Aires and gives it a clearly industrial profile.

https://es.wikipedia.org/wiki/Siam_Di_Tella

Activity: Commodities manufacturing, industrial machinery, automobiles.
Projected: 1910
Established: 1911

1911 Following a wide strike by bread makers in Buenos Aires in 1910, the city government passes a law that forces every bakery in the city to have a mechanical bread making machines. Di Tella, an 18-year-old immigrant from Italy, seizes the opportunity. He gets together with his friend Guido Allegrucci, a mechanic, and establish SIAM (Sociedad Industrial de Amasadoras Mecanicas). Their model is better than those imported, easily available and well-priced. They literally sell like hot-bread.

1922 YPF, under the direction of General Mosconi, wants to expand and starts opening gas stations all over the country. Di Tella is friends with Mosconi and offers building fuel pumps for the company, Mosconi quickly accepts.

1928 SIAM has expanded to such an extent that Di Tella decides to centralize production (dispersed on several workshops) in a huge metallurgic and mechanical factory on Avellaneda.

1929 The great depression hits as the company was living its best moment.

1930 The military coup led by Uriburu takes over. Mosconi, aligned with Yrigoyen, resigns from YPF. The contract with SIAM is rescinded. Di Tella finds himself with a huge factory but no market for his products. Seeing this, he decides to try several new production lines oriented at the booming local market.

1932 The first commercial fridges are built.

1933 The first electric engines are built.

1935 One of the great icons of SIAM starts production, the SIAM Family Fridge, a product with advanced design and building techniques. It soon becomes a staple of every homestead in the country.

1937 The company starts building pumping mechanisms for YPF.

1941 The first big power transformers are built. At the same time, a wide variety of commodities and home appliances are built.

1947 The first deep well pumps are built. The company starts making welded steel tubing, API quality, up to 323.9mm in diameter. By now the company is the largest industrial conglomerate in Latin America.

1948 Di Tella passes at age 56.

1949-1955 Di Tella’s children take over the factory. Production lines expand to include many more commodities such as washing machines, televisions, motorbikes, utility trucks and automobiles under English license. By the end of this period Siam di Tella has more than 13 factories, over 9000 employees and 250 different products.

https://es.wikipedia.org/wiki/Somisa

Activity: Metallurgy
Projected:1946
Established:1960

1963 The plant is fully operational. It can produce 632.000 t/a of liquid steel, equivalent to 450.000 of sale products.

Note: General Savio, the ideologist for the plant and the National Metallurgy Plan, conceived the plant as early as 1941 with the creation of the DGFM and the discovery of iron on Jujuy and construction of the Altos Hornos Zapla mining site.

TAMET
http://www.razonyrevolucion.org/textos/revryr/prodetrab/ryr10-09-GrandeC.pdf

Activity: Metallurgy
Established: 1902

1902 The company is created as Rezzonico, Ottonnello & Cia, the result of a fusion of three different entities: a bolt factory, a mechanical workshop and a financing company, the latter being the one which put forth the idea.

1911 The factory moves to Avellaneda. It adds cast iron bolts and rivets to its production line. By now it has a foundry that can smell both iron and bronze, which can be used in building trains, on dockyards, refrigerating plants and others. The factory also produces iron and steel building materials that are used in Buenos Aires and Brazil. 710 people work in the factory.

1913 The American Special Agent for Foreign Trade recognizes the importance of the factory as one of three such endeavors in the entire country.

1922 A company from Luxemburg takes interests in the company and decides to invest in it, a representative takes a spot in the board of directors.

1925 The company buys the assets of Talleres San Martin Compania Mercantil y Rural S.A., along with its main brands. It was one of the largest companies in agricultural tools and machinery production.

1926 The company buys Compania Argentina de Hierros y Aceros Pedro Vasena e Hijos Ltda, putting an end to nearly 25 years of fierce competition between the companies and gaining access to an industrial complex capable of producing steel ingots, thus no longer depending on imported ones. TAMET becomes the largest metallurgic company of South America and an industrial colossus in the country.

1930 TAMET buys Reta y Chiaramonte, a small metallurgic company.

1930-1945 The company continues to expand and diversify. It would help build parts for the Nahuel, an Argentinian tank design.

Yacimientos Carboníferos Fiscales
https://es.wikipedia.org/wiki/Yacimientos_Carbon%C3%ADferos_Fiscales

Activity: Coal Mining
Projected: 1941
Established: 1958 (though it functioned as a subsidiary of YPF since 1943)

1941 With the advent of WW2 Argentina faces a severe shortage of coal, an imported product, which fuels electricity generation, trains, foundries and most industries. The quickest solution was conversion to fuel oil, wood or grains. In spite of this, the board of directors of YPF creates the Mineral Coal Division, which is put in charge of studying and mining this resource.

1943 The National Board of Energy is created. The mine on Rio Turbio (Santa Cruz) becomes operational. However, moving the mineral is extremely costly. In order to reduce costs a new railroad is built that connects the site with its shipping port.

1945 The National Board of Solid Fuel Minerals is created.

1947 Rio Turbio Site 2 becomes operational.

1950 Rio Turbio Site 3 becomes operational. A depuration plant is built and a new railway line begins construction between Rio Turbio and Rio Gallegos. That same year material is already being moved between these two places, but coal had to be loaded right on the beach as Rio Gallegos had no port yet. Due to the harsh weather in the Patagonia, all construction efforts had to be done during the warm months of the year.

1951-1956 The Railway Ferro Industrial “Eva Peron” is inaugurated. A wooden dock is built on Rio Gallegos which is later expanded and improved.

1958 Y.C.F is created by presidential decree, replacing the Mineral Coal Division of YPF, which had handled the sites until then.

YPF
https://es.wikipedia.org/wiki/YPF

Activity: Oil extraction, refining and distribution.
Projected: 1907
Established: 1922

1922 Enrique Mosconi is named general director of YPF, his focus being increasing production and development of new technologies related to oil extraction. Argentina becomes the second country in the world with a state owned Oil Company after the Soviet Union.

1923-1932 President Yrioyen agrees with Mosconi’s plan to give YPF complete monopoly over petrol in the country. While there’s also participation from international companies like Shell and Esso, YPF’s production is vastly superior to them. On 1923 the first kerosene dispenser is inaugurated in Buenos Aires, six more are built in the following months. Soon after the first fuel dispenser, built by SIAM, is built.

1933 New oil wells are discovered on Tranquitas, Salta, near the border with Bolivia and Paraguay.

1938 The YPF Administrative Building is built on Buenos Aires.

1939-1954 Argentina focuses on expanding YPF in order to achieve self-sufficiency. Production is increased by 50% in the span of six years, reaching almost 85% of crude extraction. Foreign capitals are invited to the country in order to further promote quick industrialization. YPF and Drilexco (American Company) sign a contract to prospect over 40 new wells. On 1954 a new contract is signed with Standard Oil to expand operations in the southern regions of the country, this endeavor would demand an investment of 13.500.000 dollars in 4 years.

Arsenal Esteban de Luca
Several Sources, no wiki.

Activity: Arsenal, assembly of arms and vehicles.
Established: 1917 (1885)

1943-1945 Designs and builds the first argentinian tank, “Nahuel”. The design took three months while the first prototype was ready a year after. The Nahuel was very similar to the M4 Sherman, though with superior armor and overall quality.

Note: Sadly, I haven’t been able to find much more precise information. There are several pages around the web though so I believe it’s safe to say it deserves a spot.

Direccion General de Fabricaciones Militares (DGFM)
https://es.wikipedia.org/wiki/Fabricaciones_Militares

Activity: Weapon manufacturing and development.
Projected: 1938
Established: 1941

1938 The military factory of gunpowder and explosives of Villa Maria is built (it’d start production in 1942 along with the eter, gunpowder and nitrocellulose plants).

1939-1940 The Rio Tercero military industrial complex begins construction. Only 4% of it’s production would be used by the army, the rest is absorbed by the private sector.

1941 The DGFM is created under General Savio, starting production on over half a dozen factories. It also partners with private companies to create mixed companies in the mining, chemical and metallurgic areas.

1942 The Military Factory of Toluene is built on Campana, Buenos Aires, giving birth to the country’s petrochemical industry.

1943 The Toluene factory begins production and provides local industries with TNT, solvents and thinners.

1945-19XX After the end of WW2 Argentina uses the DGFM to expand its heavy industry. The country recruits engineers and scientists from Germany, Austria and Poland. On 1947 DGFM sets the ground for the creation of SOMISA, though several problems delayed its creation all the way to 1961.

Ford Argentina
https://en.wikipedia.org/wiki/Ford_Motor_Argentina#History

Activity: Vehicle manufacturer
Subsidiary of: FORD (USA capitals)
Established: 1913

1913 Ford enters the Argentinian market.

1917 The first assembly plant is built on Buenos Aires, it becames the first of Latin America.

1922 A stamping assembly plant is built on La Boca, Buenos Aires. Ford products are marketed through a net composed of 285 dealers. Later that year the rising demand makes the company hire more workers, reaching over 1.500.

1939 The outbreak of WW2 brings a cease to vehicle and components imports. Plant activity is limited to finishing units with the available materials. Lack of supplies forces the activity to cease. During this time Ford manufactures batteries and attends its clients with the sale of spare parts and accessories made in local repair shops.
