This paper presents a comprehensive strategy designed to support decision-making processes for the procurement of aeronautical products and the selection of suppliers, as required by the National Military Aviation Service in Colombia. The objectives of this study are threefold: (1) to characterize the relevant actors, characteristics of aeronautical products, applicable contractual processes, and external factors within the defense aeronautical ecosystem and its internal management systems; (2) to devise a systematic method for selecting aeronautical products for the Colombian Air Force, focusing on the potential development within the aeronautical industry; and (3) to establish a model for the selection of potential suppliers that aligns with the technical and operational requirements of state aviation. The results and discussions highlight the importance of prioritizing aeronautical products for aircraft with extended service periods, considering factors such as active production lines, operational performance indicators, and availability. Additionally, insights from interviews with technical experts underscore the importance of promoting growth within the Colombian aeronautical industry, particularly in the defence sector, by prioritizing less critical aeronautical products for local acquisition. Integrating feedback mechanisms, transparency, and long-term planning into procurement processes can enhance supplier relationships, promote strategic alignment, and drive sustainable development within the departmental aeronautical ecosystem.
