North Korea's Supreme Leader refuses to let his country's prize submarine being declared obsolete dampen his enthusiasm for it.
Kim Jong Un reportedly offered navigation tips and issued stern battle orders during a recent tour of a Romeo class submarine of the People's Navy.
North Korea's official news agency reported that the multi-talented leader "taught" the submarine's captain a "good method of navigation".
The vessels were produced for the Soviet Union for only four years before being succeeded by nuclear-powered submarines 53 years ago.
Every other navy in the world ditched the Romeo and its noisy and easily detectable diesel engine - except, of course, North Korea.
The country still boasts 20 Romeo class boats, comprising almost a third of its submarine fleet.
