Siberia ( seye-BEER-ee-; Russian: , tr. Sibir', IPA: [sbir] (listen)) is an extensive geographical region, constituting all of North Asia, from the Ural Mountains in the west to the Pacific Ocean in the east. It has been a part of Russia since the latter half of the 16th century, after the Russians conquered lands east of the Ural Mountains. Siberia is vast and sparsely populated, covering an area of over 13.1 million square kilometres (5,100,000 sq mi), but home to merely one-fifth of Russia's population. Novosibirsk and Omsk are the largest cities in the region.
Because Siberia is a geographic and historic region and not a political entity, there is no single precise definition of its territorial borders. Traditionally, Siberia extends eastwards from the Ural Mountains to the Pacific Ocean, and includes most of the drainage basin of the Arctic Ocean. The river Yenisey divides Siberia into two parts, Western and Eastern. Siberia stretches southwards from the Arctic Ocean to the hills of north-central Kazakhstan and to the northern parts of Mongolia and China. The central part of Siberia (West and East Siberian economic regions) was considered the core part of the region in the Soviet Union. Beyond the core, Siberia's western part includes some territories of the Ural region, and the far eastern part has been historically called the Russian Far East.Siberia is known worldwide primarily for its long, harsh winters, with a January average of 25 C (13 F). It is geographically situated in Asia; however, having been colonized and incorporated into Russia, it is culturally and politically a part of Europe. European cultural influences, specifically Russian, predominate throughout the region, due to it having had Russian emigration from Europe since the 16th century, forming the Siberian Russian sub-ethnic group. Over 85% of the region's population is of European descent.
The Antonov An-124 Ruslan (Russian: Антонов Ан-124 Руслан, lit. 'Ruslan'; NATO reporting name: Condor) is a large, strategic airlift, four-engined aircraft that was designed in the 1980s by the Antonov design bureau in the Ukrainian SSR, then part of the Soviet Union (USSR). The An-124 is the world's 2nd heaviest gross weight production cargo airplane and heaviest operating cargo aircraft, behind the destroyed one-off Antonov An-225 Mriya (a greatly enlarged design based on the An-124) and the Boeing 747-8. The An-124 remains the largest military transport aircraft in service. The lead designer of the An-124 (and the An-225) was Viktor Tolmachev.During development it was known as Izdeliye 400 (Product #400) in house, and An-40 in the West. First flown in 1982, civil certification was issued on 30 December 1992. In July 2013, 26 An-124s were in commercial service with 10 on order.In August 2014, it was reported that plans to resume joint production of the Antonov An-124 had been shelved due to the ongoing political tensions between Russia and Ukraine. The sole remaining production facility is Russia's Aviastar-SP in Ulyanovsk. The various operators of the An-124 are in discussions with respect to the continuing airworthiness certification of the individual An-124 planes. The original designer of the An-124 is responsible for managing the certification process for its own products, but the Russia-Ukraine conflicts are making this process difficult to manage. In 2019, there were 26 An-124s in commercial service.
