RMK-BRJ was an American construction consortium of four of the largest American companies, put together by the United States Navy during the Vietnam War to build critically needed infrastructure in South Vietnam so that the Americans could escalate the introduction of American combat troops and materiel into Vietnam. This construction contract, amounting to $1.9 billion (equivalent to $14 billion in 2017 dollars), completed a construction program deemed to be the largest in history up to that time.
