The workers of the complex have faithfully upheld the Workers' Party of Korea's (WPK) line of building an independent national economy by displaying the revolutionary spirit of self-reliance and fortitude in every annals of the revolution.

In the period of the great Chollima upswing, they manufactured an 8-m vertical lathe and a 3,000 ton-press without any advanced technology and experience to show the mettle of the Korean working class. In the 1960s, too, they performed fresh miracles and feats, cherishing in their mind the deep trust of President Kim Il Sung who put forward them in the van of the great revolutionary upsurge.

Chairman Kim Jong Il visited the complex in Juche 56 (1967) and assigned its workers to an honorable task of decisively increasing the production of new goods to implement the Party's line of simultaneously carrying on the economic construction and the defence upbuilding. The workers over-fulfilled their huge yearly plan ahead of schedule on all indices until early October of that year by giving full play to the spirit of self-reliance and fortitude and then manufactured in one year a 6,000 ton-press which is of weighty significance in the economic construction and defence upbuilding.

In the 1970s and 1980s, they made 20-m lathe, 18-m vertical lathe, 70-m closed double-housing planer, 10,000-ton press, large drilling machine, large hydro-power generating equipment, etc., greatly contributing to the development of the country's self-supporting industry.

In the 2000s, they produced modern new-type compressors by their own efforts and technology in less than one year, striking the world with wonder.

The workers of new generation at the Ryongsong Machine Complex are now fully displaying their revolutionary zeal in the struggle to carry out the new five-year plan set forth by the 8th WPK Congress as the preceding generations did, always upholding the Party with loyalty.
