When did the U.S. start making refueling stops in Yemen?

The U.S. began making refueling stops in Yemen in 1999 as part of its efforts to support operations in the region, particularly in relation to maritime security and counterterrorism initiatives. This marked a strategic decision to enhance the U.S. military presence and operational capabilities in the Arabian Peninsula. The decision was influenced by the regional dynamics at that time, including the need for logistical support for military operations in nearby areas. Understanding the context of U.S. military engagements in the late 1990s, especially in connection with counterterrorism and the importance of strategic locations like Yemen for refueling and logistics, clarifies why 1999 is the correct answer.
