Page 40 - 2020 Defence White Paper

North Korea is estimated to have secured war supplies that could last one to three
months during wartime. It is estimated that there are more than 300 munitions
factories in North Korea, including more than 100 civilian factories designed for
transformation into armament factories in a short span of time during wartime,
which are equipped with a wartime mobilization system enabling the factories
to produce military supplies rapidly during contingencies. Major military supply
production and storage facilities are believed to have been fortified underground
to ensure wartime survivability, with the ability to produce major weapons and
ammunition except combat mission aircraft. However, it is assessed that North
Korea is facing difficulties in fostering its military industry and maintaining war
sustainability in a steadfast manner as energy and raw material shortages intensify
due to the prolonged international sanctions against North Korea.
