1994: The main effort in Cuba was Operation "Sea Signal" during which Joint Task Force 160 constructed facilities to improve the quality of life of Cuban migrants at Guantanamo. By order of the 2nd Naval Construction Brigade, the 22nd Naval Construction Regiment (Forward Element) deployed to Guantanamo with Naval Mobile Construction Battalion 4 and an air detachment from Naval Mobile Construction Battalion 7. As directed by the U.S. Atlantic Command, the senior leadership of the 22nd Naval Construction Regiment (Forward Element) met with engineers from the Naval Facilities Engineering Command's Atlantic Division to develop preliminary designs for the $35 million Quality of Life Improvement Program for 20,000 Cuban migrants.
The original plan called for the construction of 37 migrant villages arranged in 11 village clusters at two locations: Radio Range and McCalla Field, approximately seven miles apart. Migrant riots in Panama led to a decision to return 7,000 refugees to Guantanamo Bay; this resulted in both an accelerated construction schedule and an enlargement of project scope for the Seabees. A detachment from the Air Force's 820th Red Horse construction unit was mobilized from Nellis Air Force Base to assist the Seabees. When the project concluded the two tent cities constructed were capable of housing almost 20,000 people. This multi-national, joint-service work-force completed an astonishing 100,000 man-days of construction effort in a harsh environment while scheduling their construction projects around the migrants and their daily operations.
