North Korean leader Kim Jong Un has instructed the factories manufacturing arms in his country to boost up the production for missile engines, artillery, and other weapons to increase the capacity as an important part of bolstering the country's defence capabilities. His instruction came as he visited multiple arms production facilities over several days amid Pyongyang's push to develop various strategic and conventional weapons, reported Reuters citing KCNA. 


Kim called for the mass production of "various kinds of cutting-edge strategic weapon engines... and thus make a great contribution to bringing about a revolution in developing new strategic weapons of our style," the agency said.


The North Korean leader's inspection which spanned from Thursday to Saturday included the production of engines for strategic cruise missiles and unmanned aerial vehicles, and shells for super large-calibre multiple-rocket launchers and transporter-erector-launchers, the KCNA stated. The launchers he inspected are normally used to fire ballistic missiles.
