The IAF has landed its Antonov-32 transport aircraft at the Pakyong Airport in Sikkim only four months after Prime Minister Narendra Modi inaugurated the airfield. Pakyong is one of the highest airfields in India and is located around 60km from the India-China border. India has been ramping up infrastructure along the nearly 4,000km border with China. The effort is supposed to boost the mobility of troops and materials in the region. The Antonov-32 is a twin-engine, turboprop military transport aircraft, designed and manufactured by Antonov Design Bureau of Ukraine.
