Located in Port Hueneme, California, NCR-1 exercises command and control over subordinate Naval Construction Force units. During peacetime these are NMCB-18, NMCB-22 and NMCB-25.
NCR-1 was first authorized in July 1967 to exercise operational control and assist its subordinate units in achieving their mission. At the time of commissioning, NCR-1 was located Armed Forces Reserve Center, Los Alamitos, California, moving to its present location at Port Hueneme, California in September 1994.
In 2003, NCR-1 was activated to backfill for the THIRTIETH NCR when it went forward in support of OIF/OEF.
Again, in 2005, NCR-1 was activated in support of OIF/OEF. This time the Regiment combined with the THIRTIETH to form a "combined" Regiment; a first ever approach. This allowed the THIRTIETH to break its one year deployment to Iraq into two six-month rotations.
Main body was activated in June 2008 and subsequently sent to Al-Anbar Province, Iraq. However, when support was needed for USMC forces in Afghanistan, the NCR-1 responded with an immediate departure to Kandahar Airfield. There, they transformed the single-tent, Camp Natasha into the vastly populated and more functional Camp Leatherneck, from which several operations were launched by U.S. Forces.
