The 20TH Naval Construction Regiment was recommissioned April 17, 1966, at the Naval Construction Battalion Center in Gulfport, nearly two decades after it’s decommissioning at the end of World War II. The Regiment was re-established to support the buildup of the Naval Construction Force (NCF) incident to the United States' involvement in Vietnam. On January 9, 2003, the command became the 20TH Seabee Readiness Group (20SRG) to better reflect it’s unique mission in the NCF.
The mission of 20TH Seabee Readiness Group, under the direction of 1ST Naval Construction Division (1NCD), is to exercise Administrative and Tactical Control of homeported active Naval Mobile Construction Battalions (NMCBs) and provide military and technical training for both active and reserve units of 1NCD. The command also ensures maximum effectiveness and operational readiness of all Atlantic Fleet (LANTFLT) units of the NCF.
Through training conducted at both CBC Gulfport, Camp Shelby and Eglin AFB, 20SRG provides these units the highest possible state of readiness to provide responsive engineering support to the Navy, Marine Corps, and other forces in military operations; to construct and maintain base facilities; to repair battle damaged facilities; to conduct defensive operations as required; and to meet disaster preparedness and recovery missions. 20SRG also serves as the personnel receiving and processing activity for all deployed LANTFLT NMCBs.
