The defence, security, aerospace, and aviation sectors operate within one of the most highly regulated and strategically sensitive legal environments in the world. Companies active in these industries must navigate complex national and international regulations concerning defence procurement, export controls, sanctions, government contracts, cybersecurity, data protection, aviation safety, foreign investment restrictions, compliance obligations, and national security investigations.

Bıçak Law Firm provides comprehensive legal and strategic advisory services to domestic and international clients operating in the defence, aerospace, aviation, security, and dual-use technology sectors. Since 2002, our firm has advised companies, executives, investors, manufacturers, contractors, suppliers, and technology providers on a broad range of legal, regulatory, compliance, and dispute-related matters arising within strategically sensitive industries. Our practice combines extensive experience in international trade compliance, criminal law, white-collar investigations, public procurement, cybersecurity, regulatory compliance, dispute resolution, and cross-border transactions. We assist clients in identifying, managing, and mitigating legal and operational risks associated with Türkiye’s rapidly evolving defence and security environment.

Türkiye’s geopolitical importance, NATO membership, expanding defence manufacturing capabilities, and increasing participation in international supply chains have created significant opportunities and legal complexities for companies engaged in defence and aerospace activities. Our firm supports clients in navigating these legal and commercial challenges while maintaining compliance with Turkish and international legal frameworks.
