The document outlines a 1953 defense agreement between the United States and Spain in which the U.S. would supply war equipment to Spain to improve their naval and military forces and develop and utilize military areas and facilities in Spanish territory, while allowing the U.S. to prepare, improve, and station civil and military personnel in those areas to contribute to international peace and security against threats to the Western world. Under the agreement, the areas prepared for joint use would remain under Spanish command and jurisdiction.
