1992: Amphibious Construction Battalion 1 arrived at Mogadishu as part of the Naval Support Element in Somalia. Within a short time ACB 1 unloaded five of the U.S. Marines’ Maritime Pre-positioning Force ships, refurbished the port, and provided fuel and water for military forces in Somalia.
Naval Mobile Construction Battalion 1 and 40 began deploying to Somalia on 10 December. Within 30 days both battalion main bodies had arrived. The 30th Naval Construction Regiment (Operational) was activated to provide command and control for the two deployed battalions. By the end of December, Seabees from NMCB 1 were convoying personnel and equipment to Baledogle, Bardera, and Baidoa to effect airfield repairs and improvements and construct base camp facilities for the deploying U.N. coalition forces. The Seabees arrived in Baledogle on 31 December and joined forces with Marines from Marine Support Wing Squadron 372 to establish landing and staging areas for CH-53 helicopters and a taxiway and turnaround pad for C-130 aircraft. The Seabees used 240,000 square feet of AM2 metal matting to construct the facility.
Near Bardera, Seabees from NMCB 1 restored a water source to a refugee camp by installing a new pump on the bank of the Jubba River. Seabees from NMCB 40 completed Operation “Clean Sweep” in Mogadishu, which consisted of removing debris (trash and car hulks) from critical areas of the city. They also prepared a site for a 300-bed Army evacuation hospital and installed 90,000 square feet of airfield at the Mogadishu airport. NMCB 40 participated in the amphibious landing at the Portof Kismayo. They quickly completed repairs to the Kismayo airfield, which allowed the rapid deployment of follow-on coalition forces to that city. Finally, the Seabees provided construction support for President George Bush’s visit to Somalia on 1 January. In addition to their tasking in support of the coalition forces, the Seabees carried out numerous civic action projects in support of the Somali people during the course of Operation “Restore Hope.”
