The paper was signed at ADEX and aims to jointly make a simulator of a multi-guided K239 rocket launcher, taking into account its adaptation to the requirements of the Norwegian Army. Oslo is presently searching for fresh WWRs, and 1 of the options analysed is the South Korean strategy acquired by, for example, Poland a fewer years ago. The conclusion of this paper thus increases its chances, although this is just an introduction to work on the simulator itself.
