The revolutionary site is associated with the undying Songun exploits of President Kim Il Sung who explored the untrodden path of building the Juche-oriented defence industry to create regular armed forces after the liberation of Korea.

After singling out army building as one of the three major tasks for building a new country he attached primary significance to the building of powerful defence industry. The first ordinance factory was built on debris in the place (the then Phyongchon-ri) after the liberation of the country under his leadership.

There is a mosaic depicting the President, leader Kim Jong Il and anti-Japanese war hero Kim Jong Suk in the revolutionary site. In June, Juche 38 (1949) the President visited the factory and fired a submachine-gun produced by workers by their own efforts and with indigenous technology and locally available materials. They were confident of the rosy future of Songun Korea.

He awarded submachine-guns of different types which had been presented by workers of the factory to anti-Japanese revolutionary fighters and had a photo taken with them. On display in the revolutionary site are the historic photo and other photos and historic relics used by the President when test-firing the submachine-gun.
