Neither choice is accurate. The figure was the displacement of the target ship, usually as identified (with varying degrees of accuracy) using the ONI-208-J recognition manual.



To answer the question in the first post, which I don't think was addressed, yes, US boats would sometimes rearm and refuel, often referred to as 'double barrelled' patrols.
