This thesis analyzes the process used to transfer U.S. Navy Perry class frigates to Turkey and issues raised during this transfer process. Up to the final step, this transfer was representative of most U.S. military equipment transfers. The relations between allied countries depend heavily on the mutual support they provide to each other. Strong relations create strong mutual support, or vice versa. Although the FMS/FML process is a very effective process for ship transfers, political issues must never be underestimated. As the Cold War came to an end, the mutual threat had changed, affecting alliances and rephrasing the causes of their existence. The effect of this change has caused more domestic oriented policies to predominate within a country's political system. Although this policy change didn't cause procedural changes in regulations and rules, the application of the decisions given and approved by the highest executive and legislative branch authorities are now more subjective and seem unpredictable. Long term and continuous repetition of this behavior could cause negative impact on alliance.
