Operation Sea Signal was a United States Military humanitarian operation in the Caribbean in response to an influx of Cuban and Haitian migrants attempting to gain asylum in the United States. As a result, the migrants became refugees at Guantanamo Bay Naval Base. The operation took place from August 1994 to February 1996 under Joint Task Force 160. The task force processed over 50,000 refugees as part of the operation. The U.S. Coast Guard and U.S. Navy rescued refugees from the sea and other migrants attempted to cross the landmine field that then separated the U.S. and Cuban military areas. Soldiers, Airmen, and Marines provided refugee camp security at Guantanamo Bay, and ship security on board the Coast Guard cutters. This mass exodus led to the U.S. immigration implementation of the Wet Feet Dry Feet Policy. The mass Cuban exodus of 1994 was similar to the Mariel boat lift in 1980.
As economic, political, and social problems continued in Cuba many citizens were looking to the United States for better opportunities. These problems led to several demonstration across Cuba in early 1994. In response to anti-government demonstrations in Havana on August 5, 1994, Fidel Castro threatened to allow a mass exodus to the United States. A few days later Castro ordered his security forces not to interfere with anyone trying to leave. Almost immediately a wave of boat people known as Balseros, set out in home made rafts, boats, and inner-tubes to try to reach the United States. These devices were hastily made, overcrowded, and lacked enough food and water for the trip. The United States Military set out to help save the lives of the Balseros, and provide safety and security for them at the U.S. military base at Guantanamo Bay. Upon finding the Balseros they were rescued and boarded unto U.S. Navy, and U.S. Coast Guard vessels. Many of the boat people were already suffering from heat injuries, and many had no food or fresh water. Several young boys and girls under the age of 10 were found floating alone on inner-tubes. The children talked of their mothers or fathers being taken by sharks during the voyage. Several refugees died during the journey and numerous rafts were found completely empty or broken into several pieces. Many of the boats that had engines were out of fuel and were floating in the current.
Early in the operation migrants were being transported to Key West, Florida. However, as the exodus did not abate, preparations began to quickly accommodate the large influx of migrants to the base at Guantanamo. Military dependents were sent back to the United States not only for security, but also to help alleviate the water shortages that would plague the base during the course of the Operation. Tent cities were constructed by military personnel at several sites across the windward side of the base, including Camp Alpha, Camp Bravo. Camp Golf, and Camp X-Ray. The base golf course and the McCalla airfield on the windward side were also reutilized as refugee holding camps. First established for Operation Sea Signal, notably Camp X-Ray, were reopened after the September 11 terrorist attacks to form the basis of the Guantanamo Bay detention camp.
