USS Niagara Falls (AFS-3)
USS Niagara FallsM/h3>
VERTREP vessel - vertical replenishment. Two helocopters on board can vertically replenish two vessels simultaneously. We also were vert-repped by her sister ship - the USS Mars. Very, very fast method.
Notice the giant helicopter pad and hangers aft. The helicopter currently on the pad, and what will work with SEBAGO, is a Sikorsky CH-46.
