They possessed a special advantage in this role, as their size permitted two or three LSTs to go simultaneously alongside an anchored battleship or cruiser to accomplish replenishment more rapidly than standard ammunition ships.
De havde en særlig fordel i denne rolle, da deres størrelse gjorde det muligt for to eller tre LSTer samtidig at lægge til ved et forankret slagskib eller krydser, så opsuppleringen kunne ske hurtigere end med almindelige ammunitionsskibe.
