Description: The history of creation of operations research methods discussed from late XVII to first half of XIX century. First operations research problems are shown to have appeared from needs od armed forces, particularly, navies. Connection is shown between the results of warfare modeling with actual progress of sea battles. Solution methods of emerging operations research problems are studied in connection with the level of mathematical education. Effect of probabilistic methods on the complexity of problems to be solved is presented as well as their importance for national defensibility.
