The US navy's newest component, the Seabees, had the same ingrained attitudes and approaches but ended up at the forefront of change. In February 1942, the CNO, Admiral Harold Rainsford Stark, recommended African Americans for ratings in the construction trades. In April, the navy announced it would enlist African Americans in the Seabees. Even so, those men were put into segregated units, the 34th Naval Construction Battalions (NCBs). Both had White southern officers and Black enlisted. Both battalions experienced problems with this arrangement, which led to the replacement of the officers. In addition, many of the stevedore battalions (special construction battalions) were segregated. However, by war's end, many of those special construction battalions were the first fully integrated units in the US navy. The war's end also brought the decommissioning of every one of those units.
