The localization ratio is one of the most important indicators reflecting a country’s ability to produce defense systems using its own resources and technologies. It represents the proportion of subsystems, software, electronic components, and critical parts developed domestically within defense projects. Beyond being a technical metric, the localization ratio is also a symbol of economic resilience and strategic power. As this ratio increases, dependency on foreign suppliers decreases, ensuring continuity, security, and operational reliability in defense systems. From this perspective, the localization ratio stands out as a fundamental criterion determining the sustainability of the defense industry.

From a more technical standpoint, the localization ratio is directly linked to R&D investments, the strength of the domestic supplier ecosystem, engineering capabilities, and technological infrastructure. Producing key elements such as engines, software, sensors, communication systems, and weapon components locally significantly raises the overall localization level of a defense platform. This increase not only provides cost advantages but also removes export restrictions and enhances competitiveness in global markets. Projects with a high localization ratio transform the defense industry into a high value-added production hub, delivering long-term strategic and economic benefits to the national economy.
