Defense companies gain greater weight in Turkish industry
Turkish defense and aerospace companies increased their presence among the top-ranked firms in the Istanbul Chamber of Industry’s (ISO) 2025 list of Türkiye’s 500 Largest Industrial Enterprises, based on net sales from production.
The ISO 500 list showed broad representation of defense and aerospace companies, ranging from prime contractors and land vehicle manufacturers to ammunition producers, electronic systems providers, aviation engine manufacturers and specialized subcontractors.
The rise of the sector’s leading companies, including Turkish Aerospace Industries (TUSAŞ), ASELSAN, ROKETSAN and HAVELSAN, stood out in the ISO 500 ranking. The country’s major defense and aerospace firms strengthened their positions among the largest industrial enterprises through higher production volumes and net sales performance.
The ranking highlighted the growing weight of the defense industry within Turkish manufacturing, reflecting not only its technological development and export capabilities but also its increasing scale of production-based sales.
