He was greeted by Senior Vice Admiral Kim Myong Sik, KPA naval commander, Rear Admiral Jin Chol Su, commander of the KPA Large Combined Unit 597, Rear Admiral Nam Chon Hak, political commissar of the unit, and other commanding officers of the unit.

He looked round the room for the education in the revolutionary history and the room devoted to its history.

Watching with deep attention the precious historic mementoes and data on a series of visits paid by President Kim Il Sung and leader Kim Jong Il to the unit, he looked back with deep emotion on the immortal exploits they performed by setting up the units of submarines and developing them.

He underscored the need for the unit to let its seamen know well about its history so that they may devote their wisdom and enthusiasm to rounding off the combat preparations with the pride and self-esteem of serving at the post associated with the army leadership exploits of the President and Kim Jong Il.

After watching various indoor trainings including the drill for launching torpedoes at the underwater comprehensive training room, he went round the interior compartments of submarine No. 748 and personally guided the actual drill aboard it.

He set the course of the submarine to the captain and taught him a good method of navigation, instilled energy and courage to display the spirit of bold attack into its seamen.

He highly praised the seamen of submarine No. 748 for their successful training.

The Party Central Committee is attaching great importance to the combined units of submarines, he said, setting forth the tasks to be fulfilled to round off the combat preparations of the unit and remarkably bolster up the underwater operation capability of submarines and modernize and fortify bases.

He underlined the need to intensify the political and ideological education among seamen so that they may creditably discharge their mission as the death-defying corps of the sea devotedly defending the party and the revolution in operational waters of vast expanse sea far away from the country.

"It is imperative to organize high-intensity trainings to help the commanding officers raise the naval and underwater operation commanding ability on the basis of studying and rounding off various proposals under the simulated conditions of actual battles," he noted, adding:

"It is necessary for them to know well about the enemy, to be well informed of the operational waters in which they will operate, and direct efforts to working out reasonable combat proposals by foreseeing any possible circumstance.

The commanding officers and seamen should clearly see through the motives of the hateful enemies watching for a chance to invade our land and put spurs to combat preparations, thinking about battles only".

He went round a mess room of the unit and crewmen's quarters and rooms for education of submarine No. 730 to take warm care of their living.

He instructed commanding officers to provide the seamen with excellent material and cultural living conditions, always remembering the teachings given by the President and Kim Jong Il that supply service precisely means a political work. He took benevolent measures to improve the living of the crewmen of the submarines of the unit.

He gave pairs of binoculars and automatic rifles to the submarines Nos. 730 and 748 as gifts and had a photo session with their crewmen.

He was accompanied by KPA Vice Marshal Hwang Pyong So, director of the General Political Bureau of the KPA, and Army General Pyon In Son, first deputy chief of the KPA General Staff and director of its Operation Bureau.
