An important consideration in the use of the LSD for transporting the barges between the atolis was the modification necessary for guch an operation, In order that the barges might be ioaded singly, a portion of the super deck had to be removed. A section of the deck was removed and stored at San Diego and two more sections were removed in the forward area, Following the movement of the barges, the two sections were replaced so that the LSD could continue with her other missions in inter-atoll transportation.
