ENThe aim of this study is to characterize the Lithuanian indigenous defense industry (IDI) and introduce an Interconnectivity Map framework as a tool to determine the strengths of interrelations among the components of the ‘Iron Triangle.’ According to the results, the Lithuanian IDI is small, mostly privately-owned, and composed of Tier 2/Tier 3 producers. The Lithuanian government is currently not focusing on the IDI as it is not contributing significantly to state economics. An Interconnectivity Map framework was applied for the Lithuanian case study. The outcome suggests that the Interconnectivity Map is a useful tool for further analyses of the Iron Triangle.
