What is the role of the Directorate of Defense Trade Controls (DDTC)?

The Directorate of Defense Trade Controls (DDTC) plays a crucial role in managing defense trade by implementing and enforcing the Arms Export Control Act (AECA) and the International Traffic in Arms Regulations (ITAR). This responsibility includes overseeing the registration of companies and individuals involved in the export of defense-related goods and services to ensure compliance with U.S. national security and foreign policy interests.

By managing defense trade controls, the DDTC ensures that sensitive technology and military equipment do not end up in the hands of unauthorized parties, thereby protecting national security. This central function aligns with the critical need for stringent oversight in defense exports to mitigate risks associated with these transactions.

The other options do not pertain to the purpose or functions of the DDTC. For example, overseeing commercial aircraft safety and regulating domestic transportation systems fall under different agencies focused on transportation safety rather than defense trade. Similarly, coordinating international trade policies is broader and not specifically tied to the defense trade, which the DDTC is focused on.
