Obsolete weapons in modern militaries

Purpose This article examines the concept of weapon obsolescence in modern militaries, challenging the prevailing notion that newer weapons are inherently superior. It aims to establish a comprehensive classification of obsolete weapons, considering factors beyond purely technological causes of obsolescence. Design/methodology/approach The study adopts a two-step methodology. First, it develops a classification of weapon obsolescence based on nature, origin and intentionality of causes. Second, it proposes a matrix for the potential use of different categories of obsolete weapons, considering their technological features and intended operational roles. Findings The research reveals that obsolescence is not solely determined by age or technological advancement. Weapons often deemed obsolete can still play crucial roles in modern warfare, and their continued use may represent a deliberate strategic choice rather than simply a necessity. Research limitations/implications The study focuses exclusively on physical assets, specifically heavy and light weapons, and does not consider other military inventory items such as software or communication equipment. Practical implications The findings suggest that obsolete weapons can, under certain conditions, be effectively employed, with significant implications for defence strategies, particularly for states unable to afford newer armaments. Originality/value This article contributes to the discourse by providing a structured framework for understanding and employing obsolete weapons. It moves beyond the traditional logistics-oriented perspective, incorporating historical, legal and practical dimensions of obsolescence.
